Abstract
Description
[0001] Technical Topics
[0002] The present invention relates to the field of measurement and detection technology, and in particular to a detection method, a measuring device and a data processing device for environmental equipment. Background Art
[0003] Environmental equipment is a device used to provide environmental physical quantities in a specific environmental space. It is widely used in measurement, medicine, food and other fields. Environmental physical quantities have spatial properties and are usually manifested as a "field", such as temperature field, temperature and humidity field, temperature and pressure field, pressure and humidity field, etc.
[0004] In order to verify the working performance of the environmental equipment, it is necessary to test the environmental equipment, including testing the "field" formed by the aforementioned environmental physical quantities. Specifically, first, according to the indicators of the "field", multiple test points that can describe the "field" are determined, and each measuring probe is arranged at each test point, so that the measurement results of each measuring probe can reflect the "field" as comprehensively as possible. Secondly, the environmental equipment is controlled to provide environmental physical quantities. At this time, a target environmental value is usually set, and the environmental equipment is configured to provide environmental physical quantities that reach the target environmental value. Thirdly, when the environmental physical quantity reaches the target environmental value, each measuring probe measures at the same time, and this measurement process may last for a period of time. Finally, the data of each measuring probe is integrated to form a data group describing the "field". By processing it, the overall and average conditions of the "field" can be obtained, as well as the changes in the "field", so as to fully express the actual situation of the "field". By comparing the actual situation with the target environmental value and the nominal situation, the environmental equipment can be evaluated, calibrated, and verified.
[0005] The above process has a problem, that is, when processing the detection data, how to determine the corresponding relationship between the measurement probe and the point to be measured.
[0006] The prior art mainly solves the above-mentioned problem through manual configuration. One of the solutions is to pre-store the correspondence between the measuring probe and the point to be measured, and then arrange the measuring probe at the point to be measured according to the pre-stored relationship. The second solution is to arrange the measuring probe at the point to be measured, and then record the arrangement. Obviously, whether it is solution one or solution two, since the record of the correspondence relationship and the actual arrangement are separated, there is a risk of human error or wrong arrangement, which leads to the final test result being inconsistent with the actual result, directly affecting the credibility of the test result.

For those skilled in the art, the present application can be fully understood without the description of these details, and it can also be understood that these details are based on non-creative deformation of the prior art, obvious changes, replacement of conventional technical means, etc.
[0030] In the description of this embodiment, unless otherwise expressly stated or those skilled in the art can determine meaninglessly based on relevant representations: the word "comprising" does not exclude other units or steps; the singular does not exclude the plural; expressions such as "first XX", "second XX", etc. do not limit the number or select the order, but are used to distinguish different functional individuals in the same type of objects. At the same time, this distinction is mainly functional and does not include the distinction between specific entities. Those skilled in the art can understand that if the first, second, etc. individuals can only solve the technical problem independently of each other, then the first, second, etc. in the scheme represent different specific entities. If some or all of the first, second, etc. individuals can be used as a specific entity and can also solve the technical problem, then the scheme described in this embodiment includes this situation and should also fall within the scope of protection intended by this application; multiple structures, components, and units can be implemented as a whole when feasible, and a single structure, component, and unit can be implemented by multiple specific entities when feasible.
[0031] This embodiment provides the main feasible solutions and the improved solutions of the main feasible solutions. It can be understood that the main feasible solutions can solve technical problems independently, and combined with the improved solutions can better solve technical problems or solve new technical problems. The combination of some improved solutions can better solve technical problems or solve new technical problems. The feasible methods of these combinations are all within the scope of the content disclosed in this embodiment.
[0032] This embodiment provides a detection method for detecting environmental equipment, which can be used to verify, calibrate, test, inspect, test or other similar operations on the environmental equipment, wherein the environmental equipment is used to provide environmental physical quantities in the environmental space, and the environmental physical quantity is at least one of temperature, pressure and humidity.
[0033] Generally, environmental equipment provides an environmental physical quantity field, which may overlap with the environmental space or may be smaller than the environmental space. That is, during the working process, not only the environmental physical quantity at a certain point affects the working performance of the environmental equipment, but also affects the working performance of the environmental equipment within a certain space. For example, for a temperature field device, the main focus is on its center position. At the same time, attention is also paid to whether the temperature field of the temperature field device near the center position is uniform, or whether it changes as required. Generally, in order to ensure performance, environmental equipment places the environmental space in a closed or semi-closed chamber inside it, but it does not rule out that in some cases, some environmental equipment provides environmental physical quantities in an open laboratory or other space. In this case, the environmental space is located outside the environmental equipment. It can be understood that in either case, the environmental physical quantity and environmental space can be determined based on basic information such as the factory design and manufacturing indicators of the environmental equipment.
[0034] S1, determining at least two locations to be measured, where the locations to be measured are distributed in the environmental space.
[0035] The position to be tested can be determined according to the purpose of the test. Generally, unless there is a structure in the environmental space to form a restriction on the position to be tested, the position to be tested is not a fixed position in the environmental space before the purpose of the test is determined. It is understandable that in the best case, if an environmental physical quantity field is to be fully described, when selecting and determining the position to be tested, not only the key position should be considered, but also some other positions that can characterize the change of environmental physical quantity with space. At the same time, it is understandable that the higher the distribution density of the position to be tested, the more precise the measurement of the change of environmental physical quantity with space.
[0036] S2, determining at least two measuring devices, the measuring devices comprising environmental sensors, the environmental sensors being used to measure environmental physical quantities, arranging the measuring devices at positions to be measured, so that at least two measuring devices correspond to at least two positions to be measured one by one.
[0037] Based on the number of positions to be measured and the information on environmental physical quantities, the measuring device can be determined. Generally speaking, based on the number of positions to be measured and the information on environmental physical quantities, it can be determined how many positions to be measured need to be detected and what the environmental physical quantities to be detected at these positions to be measured are. Furthermore, based on the purpose of detection, the accuracy of the measuring device also needs to be considered, that is, the accuracy of the measuring device should generally be equal to or higher than the accuracy of the environmental equipment, so that the measurement results generated by the measuring device are sufficiently reliable for the environmental equipment.
[0038] In order to achieve the purpose of measuring environmental physical quantities, the measuring device needs to be configured with at least one environmental sensor. In some cases, it is understandable that if there are two environmental physical quantities that need to be measured at a certain position to be measured, for example, in a temperature and humidity field, it may be necessary to measure the temperature and humidity of the center position at the same time. In some cases, a temperature measuring device and a humidity measuring device can be selected and arranged at the position to be measured at the same time. In other cases, a measuring device with both a temperature sensor and a humidity sensor can also be selected. These operations have no effect on the implementation plan.
[0039] After selecting and determining the measuring device, it is necessary to place the measuring device at the position to be measured. Generally speaking, the measuring device placed at the position to be measured should be a measuring device that can perform the measurement task. For example, the temperature probe should be placed at the position to be measured for measuring temperature, and the humidity probe should be placed at the position to be measured for measuring humidity. In some cases, if a probe has the ability to measure two or more environmental physical quantities, but only one of them is used during the measurement process, then the probe can be regarded as a probe with a single measurement capability.
[0040] For the example described above, if you want to measure a temperature and humidity field, you know that you need to measure 9 temperature test positions and 1 humidity test position, then you can determine 9 temperature probes and 1 humidity probe that meet the detection requirements (the temperature probe and humidity probe at this time can be equivalent to the aforementioned measuring devices). At this time, there is no one-to-one correspondence between each measuring device and the test position. The 9 temperature probes are respectively arranged at the 9 temperature test positions, and the 1 humidity probe is arranged at the humidity test position. At this time, a one-to-one correspondence between each measuring device and each test position is formed.
[0041] S3, when the measuring device is located at the position to be measured, the environmental equipment is controlled to provide environmental physical quantities, the measuring device measures the environmental physical quantities, and environmental measurement information corresponding to the measuring device is generated.
[0042] In the preparation stage, generally, each measuring device is arranged in each position to be measured, so that the measuring device and the position to be measured correspond one to one, that is, each position to be measured has a corresponding measuring device for measurement. After completing the preparation stage, the detection stage can be entered. In the detection stage, generally, a target environmental value is given. The so-called target environmental value refers to one or a group of target values. The environmental physical quantity in the environmental equipment will tend to change in the direction of the target value until it reaches the target value. After that, based on this target environmental value, the environmental equipment is controlled. The control of the environmental equipment can be achieved by the control capability inside the environmental equipment, or by means of an external control module. The environmental equipment begins to generate environmental physical quantities in the environmental space, and correspondingly, each measuring device begins to measure the environmental physical quantities. In theory, if each measuring device can measure the environmental physical quantity independently, but in a better case, each measuring device measures the environmental physical quantity synchronously. The synchronization mentioned here includes, firstly, each measuring device performs measurement at the same time, rather than measuring in sequence, and secondly, each measuring device is configured with the same acquisition frequency (this configuration can be realized in combination with an external data processing device), so that the number of measurement data collected by each measuring device is the same. It should be noted that in some cases, due to design, manufacturing and other issues, the synchronization process may be implemented only in part of the detection process. At the same time, there may be deviations in the synchronization between different measuring devices. As long as they meet the detection requirements and the above description of synchronization, they will still be regarded as a synchronized state. After measuring, each measuring device generates environmental measurement information respectively. The so-called environmental measurement information is generally embodied as a group of measurement data. According to different acquisition time and acquisition frequency, the group of measurement data may be one or more. The measurement data collected by the measuring device forms a natural correspondence with it, that is, the environmental measurement information corresponds to the measuring device. Further, different measuring devices correspond to the environmental measurement information generated by them.
[0043] S4, measure and obtain the relative position between at least two measuring devices, and process to obtain a device distribution model, wherein the device distribution model includes information about the position of a first device, and the information about the position of the first device describes the relative position relationship between the first measuring device and other measuring devices when the measuring device is located at the position to be measured, and the first measuring device is one of the at least two measuring devices. It can be understood that the information about the position of the first device is different from the information about the position of the other devices, and this difference is at least reflected in one of the relative distance and the relative direction, specifically, either reflected in the difference in relative distance, or reflected in the difference in relative direction, or reflected in the difference in relative distance and relative direction.
[0044] The measurement and acquisition here may be completed by one detection action, or may be achieved by a combination of two or more detection actions. The purpose of this combined operation is to obtain the relative position between each measuring device. Specifically, the method of measuring and obtaining the relative position between at least two measuring devices can be a direct ranging method or an indirect positioning method. For example, in the direct ranging method, mutually adapted communication ranging modules are provided in the measuring device. Based on the communication ranging module, when there are two measuring devices, the relative distance can be obtained through communication ranging. For another example, in the direct ranging method, through other ranging schemes of the prior art, when there are three or more measuring devices, the relative distance between each measuring device can be obtained through communication ranging. For another example, in the indirect ranging method, each measuring device is moved from the same pre-placed position to each position to be measured, and the moving distance is recorded, and the moving direction can also be recorded. Then the position of each measuring device relative to the reference position can be obtained, and then the position conversion is performed based on the pre-placed position to obtain the relative position between each measuring device. Another example is the indirect distance measurement method, which moves each measuring device from different pre-placed positions to each position to be measured. Unlike the previous example, when the position conversion is performed based on the pre-placed position, the relative position between each pre-placed position should also be added. In this way, the relative position between each measuring device can be obtained. Another example is the comprehensive distance measurement method, which can partially use the direct distance measurement method and partially use the indirect distance measurement method in the process of measuring and acquiring the same relative position, or both the direct distance measurement method and the indirect distance measurement method are used. It can be understood that the direct distance measurement method is more dependent on the ability of the distance measurement module, and the indirect distance measurement method needs to consider the pre-placed position. The combination of the two is more suitable for different work scenarios.
[0045] After obtaining the relative positions of the various measuring devices, they are processed to obtain a device distribution model. In some cases, this operation can also be directly incorporated into the previous measurement and acquisition process. It can be understood that one of the key elements of the device distribution model is the relative positions of the various measuring devices.
[0046] The device distribution model, as the name implies, is a model stored in a computer or other storage device, which describes the distribution of measuring devices. More specifically, the device distribution model mainly describes the distribution of measuring devices through the relative position relationship between the measuring devices.
[0047] The device distribution model includes at least the information of the first device location. If there are more, it can include the information of two or more device locations. The information of the first device location, as the name implies, describes the first device location. To further define the first device location, firstly, whether it is the first measuring device or the first device location, it can be a measuring device and device location with specific detection significance, or it can be any measuring device and device location. Secondly, the device location describes the relative position relationship between the measuring device and other measuring devices. When there are only two measuring devices, the device location describes a relative position relationship. In some cases, if there are three or more measuring devices, the device location will be a set of data. For example, if there are also a second measuring device and a third measuring device, the information of the first device location includes the relative position relationship between the first measuring device and the second measuring device, and also includes the relative position relationship between the first measuring device and the third measuring device. Generally, the relative position relationship is expressed by relative distance and / or relative direction. For example, P1={P 12 ,P 13 ,……,P 1n}, P 12 =(D 12 ,L 12 ), where P1 represents the information of the location of the first device, P 12 represents the relative position relationship between the first measuring device and the second measuring device, P 13 represents the relative position relationship between the first measuring device and the third measuring device, D 12 represents the relative direction of the first measuring device and the second measuring device, L 12 It represents the relative distance between the first measuring device and the second measuring device, and so on. Again, the first device position or similar device positions are not a collection of relative position relationships at any time, but the device positions during the detection process. Combined with the previous description, it can be seen that during the detection process, each measuring device is located at the position to be measured.
[0048] S5, obtaining information of at least two positions to be measured, and processing to obtain a distribution model to be measured, wherein the distribution model to be measured includes information of a first position to be measured, and the information of the first position to be measured describes the relative position relationship between the first position to be measured and other positions to be measured, and the first position to be measured is one of the at least two positions to be measured. It can be understood that the information of the first position to be measured is different from the information of the other positions to be measured, and this difference is at least reflected in at least one of the relative distance and the relative direction, specifically, either reflected in the relative distance, or reflected in the relative direction, or reflected in the relative distance and the relative direction.
[0049] The information of at least two locations to be tested is obtained, including direct and indirect methods. Direct acquisition, as the name implies, is to directly obtain the information of the location to be tested, including the location of the location to be tested in the environmental space. Indirect acquisition, the information obtained is the information of the environmental space or environmental equipment. After the information is processed according to preset rules, the information of the location to be tested is obtained. For example, the computer pre-stores the spatial distribution model of each environmental equipment and also pre-stores the detection rules. The detection rules provide one or more combinations of locations to be tested. During the working process, according to the specific situation of the environmental equipment to be tested, the appropriate spatial distribution model and combination of locations to be tested are selected to obtain the information of each location to be tested.
[0050] The distribution model to be measured, as the name implies, is a model used to describe the distribution of the positions to be measured. In the present embodiment, the distribution model to be measured describes the distribution through relative position relationships. Specifically, the distribution model to be measured includes at least the information of the first position to be measured, and if there are more, it may include the information of other positions to be measured. Similar to the first measuring device in S4, the first position to be measured may be a position to be measured with a specific detection significance, or it may be any position to be measured. At the same time, the information of the first position to be measured is also composed of one or more relative position relationships. For example, if there are also a second position to be measured and a third position to be measured, then the information of the first position to be measured can be expressed as p1={p 12 ,p 13 ,……},p 12 =(d 12 ,l 12 ), where p1 represents the information of the first position to be measured, p 12 represents the relative position relationship between the first position to be measured and the second position to be measured, p 13 represents the relative position relationship between the first position to be measured and the third position to be measured, d 12 Indicates the relative direction between the first position to be measured and the second position to be measured, l 12 It represents the relative distance between the first position to be measured and the second position to be measured, and the others can be deduced by analogy.
[0051] S6, compare the device distribution model with the distribution model to be tested, and if the information of the first device position is the same as the information of the first position to be tested, determine the corresponding relationship between the first measuring device and the first position to be tested, and process the environmental measurement information of the first measuring device accordingly to generate a test result. There are many ways to compare, which can be determined or selected according to the specific composition and form of the device distribution model and the distribution model to be tested, the purpose of detection, etc.
[0052] For example, in one case, the accuracy of the temperature field center or other similar key points is particularly concerned. Correspondingly, a measuring device with higher accuracy is selected as the first measuring device. The device distribution model only includes the information of the first device position, and the distribution model to be measured only includes the information of the first position to be measured. Then the so-called comparison is to directly compare the information of the first device position with the distribution model to be measured. According to the comparison result, it can be judged that if the information of the first device position is the same as the information of the first position to be measured, it can be considered that the first device position and the first position to be measured are the same. If they are different, it means that the first measuring device is not arranged at the first position to be measured, and there is a problem with the current measurement result, which needs to be re-measured. It should be noted that the same here is not the same in the strict sense, but the same within the error tolerance range, including completely the same, basically the same, similar and equivalent. Based on this, it can be determined that the environmental measurement information generated by the first measuring device describes the first position to be measured, and the environmental measurement information generated by the first measuring device is processed, and the deviation value, fluctuation and other parameters are calculated. The result is compared with the allowable deviation, allowable fluctuation, etc., so as to detect the environmental equipment.
[0053] For example, in another case, what needs to be detected is a field with a center. At this time, the parameters to be considered include the change gradient of the field physical quantity, and this change gradient is expressed by the deviation between the center and the surroundings. Correspondingly, the device distribution model includes the information of each device position, and the distribution model to be measured only includes the information of the first position to be measured. At this time, the comparison includes comparing the information of the first position to be measured with the information of each device position one by one. Since the information of each device position is different, the information of the first position to be measured can find the information of the unique device position that is the same as the corresponding one, that is, the information of the first device position. After determining the correspondence between the two, it is no longer necessary to distinguish which position to be measured other measuring devices are in, but directly calculate the detection data such as the center temperature and the change gradient to generate the detection result.
[0054] For another example, in another case, through data analysis, it is found that the data obtained by a certain measuring device is abnormal, and it is necessary to determine the measured position with the actual direction abnormality. Correspondingly, the measured distribution model includes information of each measured position, and the device distribution model includes information of the device position corresponding to the abnormal point measurement device, that is, the information of the first device position. At this time, the comparison includes comparing the information of the first device position with the information of each measured position one by one. Since the information of each measured position is different, the information of the first device position can find the information of the unique device position that corresponds to it, that is, the information of the first measured position, and determine the first measured position accordingly. After determining the correspondence between the two, the situation of the normal area, the situation of the abnormal area, etc. can be given to generate the detection result.
[0055] For another example, in another case, it is necessary to determine the correspondence between each measuring device and the position to be measured. Correspondingly, the distribution model to be measured includes information of each position to be measured, and the device distribution model includes information of each device position. At this time, the comparison includes comparing the information of each position to be measured with the information of each device position, wherein it may occur that the information of the first position to be measured is compared with the information of other device positions, and / or the information of other positions to be measured is compared with the information of the first device position. Since the information of the two sides of the comparison does not match, the comparison object is replaced to continue a new comparison. It may also occur that the information of the first position to be measured is compared with the information of the first device position. Since the information of the two sides matches, the correspondence is saved, and at the same time, it is determined that the two sides of the correspondence no longer participate in the comparison, and a new comparison object is replaced to continue a new comparison. This cycle is repeated until each position to be measured has a device position corresponding to it. According to the obtained correspondence, it can be determined that each environmental measurement information from the measuring device describes the environmental conditions of which position to be measured, and the detection result can be generated based on this.
[0056] There are other examples, which are not listed one by one.
[0057] It can be understood that S1-S6 do not represent a sequential relationship. Specifically, all or part of S2 may occur before, after, or simultaneously with S1, S3 occurs after S2 and S1, all or part of S4 may occur simultaneously with S2, or between S2 and S3, or simultaneously with S3, or later than S3, all or part of S5 may occur simultaneously with S1, or after S1, or before, simultaneously with, or after S2, S3, and S4, and S6 occurs after S4 and S5.
[0058] It can be understood that all or part of the steps in S1-S6 can be divided into two or more sub-steps. For these sub-steps, the sub-steps after division may not be executed continuously, but one sub-step is executed first, then another step, and then another sub-step is executed. For example, at least two measuring devices can be determined first, then at least two positions to be measured can be determined, and then the measuring devices can be arranged at the positions to be measured.
[0059] It is understandable that when faced with the technical problem of how to determine at what position a measuring device is located, the general solution is to identify the position of the measuring device in the environmental space, either manually or by using a camera recognition, ranging or other schemes, that is, directly identify at what position the measuring device is located, and establish a corresponding relationship between the measuring device and the position to be measured. Different from the aforementioned general solution, the solution of this embodiment uses such a detection process situation, during the detection process, there is a one-to-one correspondence between the measuring device and the position to be measured in space, when there are two or more measuring devices and the position to be measured, the relative position relationship between different measuring devices is at least partially different, and the relative position relationship between different positions to be measured is at least partially different. Based on the aforementioned detection process situation, this embodiment determines the information of one or a group of device positions through the relative position relationship between the measuring devices, and then compares the information of the device position with the information of the position to be measured. This comparison can obtain a unique result, and achieve the purpose of determining the corresponding relationship between the measuring device and the position to be measured.
[0060] The aforementioned technical solution of this embodiment can be improved or optimized to produce the following improved examples.
[0061] Improvement example 1, measuring the relative position between the at least two measuring devices, including: determining a reference position, the reference position is located outside the environmental space; the measuring device moves between the reference position and the position to be measured, the measuring device passes through the reference position and the position to be measured, measures and generates device displacement information, the device displacement information is used to describe the moving distance and moving direction of the measuring device; based on the device displacement information of at least two measuring devices and the information of the reference position, the relative position between the at least two measuring devices is obtained.
[0062] Based on the above-mentioned improvement example 1, this embodiment provides a method for measuring the relative positions between various measuring devices.
[0063] S4.1, the reference position must be determined. The reference position here can be determined specifically or in conjunction with the implementation of other means. Similar to the determination of the position to be measured and the determination of the measuring device, the determination includes but is not limited to selection, objective formation or other methods. The technical result of this action is that once determined, it will not change during the current detection process. In the next detection process, the content determined last time can be directly used or re-determined.
[0064] Generally, in the best case, only one reference position is determined, that is, all measuring devices share the same reference position. In other cases, it is not convenient to use one reference position due to the large distribution of the site, so at least some of the measuring devices can correspond to other reference positions. In this case, there are two or more reference positions. However, no matter how many reference positions there are, the reference position itself is in a determined state and cannot change during the detection process.
[0065] S4.2, after determining the reference position, the measuring device can be moved and the displacement can be measured at the same time. In a preferred case, the movement of the measuring device is accompanied by at least one of the following two operations. First, in the preparation stage of the detection process, the measuring device needs to be arranged at the position to be measured. In this process, the measuring device can be placed at the reference position first and then moved from the reference position to the position to be measured. It can also be placed at another position first and pass through the reference position in the process of moving to the position to be measured. Second, in the end stage of the detection process, the main operation of the detection is basically completed and the measuring device needs to be withdrawn from the position to be measured. In this process, the measuring device can move from the position to be measured to the recovery position as the reference position, or from the position to be measured to other recovery positions, and pass through the reference position in the process of moving to other recovery positions. It can be understood that the movement of the aforementioned measuring device is not limited to the movement in the above two preferred cases.
[0066] During the movement, the displacement information of the measuring device is measured to obtain the device displacement information. The so-called displacement information and device displacement information both include displacement distance and displacement direction, so as to describe the displacement trajectory of the measuring device. Since the measuring device moves between the reference position and the position to be measured, and passes through the reference position and the position to be measured during the movement, after the displacement trajectory is calculated, one end of the displacement trajectory is the reference position and the other end is the position to be measured. As mentioned above, since the reference position is determined, the position to be measured is also determined along with the determination of the reference position and the displacement trajectory.
[0067] It should be noted that, since there are multiple measuring devices, the aforementioned S4.1 and S4.2 may be performed alternately, and S4.2 may be divided into multiple sub-steps, for example, determining the reference position of the first measuring device, moving and measuring the moving trajectory of the first measuring device, and then determining the reference position of the second measuring device, and moving and measuring the moving trajectory of the second measuring device.
[0068] S4.3. After executing the above-mentioned processes of S4.1 and S4.2 for each of the measuring devices, multiple groups of device displacement information can be obtained, and each group of device displacement information corresponds to a measuring device. For example, by calculating the displacement information of the first device, the actual layout position of the first measuring device (which is a position to be measured, but it is not yet possible to determine which position to be measured it is) and the relative position (relative distance and relative direction) of the reference position can be obtained; by calculating the displacement information of the second device, the actual layout position of the second measuring device and the relative position of the reference position can be obtained.
[0069] Furthermore, combined with the information of the reference position, if the reference position is the same position, then the above calculation results can obtain the actual layout position of each measuring device and the relative position of the same reference position, and the relative position between each measuring device can be determined to achieve the purpose of measurement and acquisition. If the reference position is two or more positions, for example, the first measuring device corresponds to the first reference position, and the second measuring device corresponds to the second reference position, then when processing, the relative position of the first reference position and the second reference position must be introduced first (usually included in the reference position information), and the device displacement information of each measuring device must be converted into the same reference system. Subsequently, it can be processed according to the operation of the same reference position, and the purpose of measurement and acquisition can be achieved.
[0070] For further improvement, there may be Improvement Example 2, which can be combined with the present embodiment and Improvement Example 1 thereof, wherein the measuring device includes a displacement sensor, and the displacement sensor is used to measure the relative displacement of the measuring device; before generating environmental measurement information, the measuring device is arranged at a reference position and the device displacement information is started to be recorded, and / or, after generating environmental measurement information, the measuring device is arranged at a reference position and the device displacement information is stopped to be recorded. In some cases, Improvement Example 2 is a further improvement on the process of determining the reference position in Improvement Example 1.
[0071] Specifically, in order to measure the displacement information of the device, the measuring device includes not only an environmental sensor but also a displacement sensor. Therefore, the displacement sensor and the measuring device are integrated, and the displacement sensor can be used to measure the relative displacement of the measuring device.
[0072] In a preferred solution, in order to help determine the reference position, at least one of the following two operations may be used:
[0073] One of the operations is that before the environmental measurement information is generated, that is, before the detection process, the measuring device has not yet been arranged at the position to be measured. At this time, the measuring device is first arranged at the reference position and the device displacement information is started to be recorded. If this is done, the starting recording point of the device displacement information corresponds to the reference position. It can be understood that as long as the recording point to be measured when the measuring device reaches the position to be measured is found and the data between the starting recording point and the recording point to be measured is processed, the device displacement information and the relative position relationship expressed by it can be obtained;
[0074] The second operation is, after the environmental measurement information is generated, that is, the main detection process has been completed, and the measuring device has not been disassembled but is located at the position to be measured, at this time, the measuring device is arranged at the reference position and the device displacement information is stopped. If this is done, the end recording point of the device displacement information corresponds to the reference position. It can be understood that by combining the data between the recording point to be measured and the end recording point for processing, the device position information and the relative position relationship it expresses can be obtained.
[0075] It is understandable that the above two solutions can complete the work independently, and after being combined, they can complete the work better.
[0076] The combined situation is explained as follows: if the starting recording point corresponding to the reference position and the ending recording point corresponding to the reference position are determined respectively according to the aforementioned operation one and operation two, subsequently, the measuring device continues to collect the device displacement information. At this time, the device displacement information may include four key points, the first key point, the starting recording point, the second key point, the first recording point to be measured, the third key point, the second recording point to be measured, and the fourth key point, the ending recording point; in the first displacement recording stage, between the starting recording point and the first recording point to be measured, since the measuring device is in the process of moving, it can be found that the device displacement information will be reflected in the corresponding period of time as a change in relative distance or It is a non-zero value, and / or the relative direction changes. In the second displacement recording stage, between the first recording point to be measured and the second recording point to be measured, since the measuring device is stable at the position to be measured for measurement, it can be found that the device displacement information will be reflected in the corresponding time period as the relative position remains unchanged (remains zero), and the relative direction remains unchanged. In the third displacement recording stage, between the second recording point to be measured and the end recording point shore, since the measuring device is in the process of moving, it can be found that the device displacement information will be reflected in the corresponding time period as the relative distance changes or is a non-zero value, and / or the relative direction changes. The above judgment can be determined by using a computer to complete the processing with a smaller amount of calculation.
[0077] It can be found that, firstly, by using one of the first displacement recording stage and the third displacement recording stage, the relative position information between the corresponding position to be measured and the reference position can be calculated. Secondly, by using the second displacement recording stage, the credibility of the environmental measurement information collection process can be verified. For example, it is determined whether the collection time of the environmental measurement information is included in the second displacement recording stage. If it is partially or completely not included, it indicates that the environmental measurement information was not located at the position to be measured when it was collected, and the data credibility is questionable. For another example, the stability of the device displacement information in the second displacement recording stage is checked. Based on this, it is determined whether the measuring device has vibrated, rotated, etc. during the continuous collection of environmental measurement information. Further, it can be determined in combination with the environmental measurement information at the corresponding moment whether such vibration or rotation has an impact on the environmental measurement information. Based on this, the data credibility of the environmental measurement information is evaluated.
[0078] A further improvement that can be combined with this embodiment and Improvement Example 1 and Improvement Example 2 is Improvement Example 3.
[0079] In improved example three, a data processing device is also involved in the detection method of this embodiment, which is used to process environmental measurement information and device displacement information, and a near-field communication channel is established between the data processing device and the measuring device; based on the near-field communication channel, the data processing device sends a start measurement instruction to the measuring device, so that the measuring device starts to record the device displacement information, and the data processing device is configured to determine the starting recording position of the device displacement information as the reference position, and / or, based on the near-field communication channel, the data processing device reads the environmental measurement information and device displacement information from the measuring device, and the data processing device is configured to determine the ending recording position of the device displacement information as the reference position.
[0080] Specifically, this embodiment provides a data processing device that is matched with a measuring device to implement a detection solution.
[0081] The data processing device can be a host computer, a test host, a data logger or other equipment with data processing and storage capabilities, which can perform data processing. Basically, after the measuring device collects environmental measurement information and device displacement information, it will be transmitted to the data processing device. The data processing device processes it, obtains the test results, and generates a test report.
[0082] The data processing device of this embodiment has a host near-field communication module, and correspondingly, the measuring device has a device near-field communication module. The host near-field communication module and the device near-field communication module are compatible and can establish a near-field communication channel.
[0083] The measuring device is an immersion measuring device, which comprises a device storage module and a device processing module. The device processing module is respectively connected to an environmental sensor, a displacement sensor, a device storage module and a device near field communication module.
[0084] For example, the first measuring device participates in the detection process. In the initialization state, the first measuring device is in a power-saving silent state. In this state, the first measuring device does not perform measurement to save resources. First, the first measuring device is activated and the first measuring device is placed close to the near-field communication position of the data processing device. When the two are close enough, a near-field communication channel is established, and the data processing device sends a measurement instruction to the first measuring device. The measurement instruction is transmitted to the first measuring device through the near-field communication channel. The first measuring device starts to measure, including starting to measure environmental data and displacement data, and storing the environmental data and displacement data in the device storage module. At this time, the first measuring device is in an activated state; thereafter, the first measuring device is moved to the first position to be measured and detachably fixed. During the movement, the first measuring device continues to measure environmental data and displacement data; then, Start the environmental equipment, and the first measuring device continues to measure; then, when the preset collection time is reached, stop the environmental equipment, take the first measuring device out of the environmental space, and approach the near-field communication position of the data processing device again. During this process, the first measuring device is still storing and measuring. When the two are close enough, a near-field communication channel is established, and the data processing device sends a read and stop working instruction to the first measuring device. Based on the read instruction, the first measuring device transfers the environmental data and displacement data stored in the device storage module to the data processing device. After the transfer is completed, the uploaded data in the device storage module is deleted, and the first measuring device returns to the power saving state; then, at this time, the data processing device obtains a set of environmental data and a set of displacement data. It can be found that this set of environmental data contains the aforementioned environmental measurement information, and this set of displacement data contains the aforementioned device displacement information.
[0085] Since the distance of near-field communication is very short and the data processing device generally processes a stable and motionless state, when the data processing device and the first measuring device establish a near-field communication channel for the first time, not only the measurement instruction is transmitted, but also the reference position (i.e., the near-field communication position of the data processing device) is determined based on the instruction. When the data processing device and the first measuring device establish a near-field communication channel for the second time, not only the transmission of environmental data and displacement data is completed, but also the reference position is determined based on the connection.
[0086] It can be understood that the aforementioned first measuring device is a non-specific measuring device, and each measuring device can implement measurement and data transmission according to this process.
[0087] Based on the aforementioned improvement example three, preferably, there may be an improvement example four. In this embodiment, based on the start measurement instruction, the environmental sensor starts measuring and generates environmental data, and at the same time, the displacement sensor starts measuring and generates displacement data; the data processing device reads the environmental measurement information and the device displacement information from the measuring device, including that the data processing device obtains the environmental data and the displacement data from the measuring device; the data processing device processes the displacement data and determines the moving state of the measuring device, and accordingly divides the displacement data into middle displacement data in a non-displacement state, front displacement data in a displacement state, and rear displacement data in a displacement state; based on the front displacement data, the relative position relationship from the reference position to the position to be measured is obtained; based on the rear displacement data, the relative position relationship from the position to be measured to the reference position is obtained; based on the recording time of the middle displacement data, the environmental data of the corresponding time is determined, which is used to determine the environmental measurement information.
[0088] The above-mentioned Improvement Example 3 and Improvement Example 4 solve the following technical problem: in the process of preparing and conducting the test, it is expected not to increase or avoid increasing human instructions as much as possible, but to use objective data for evaluation or judgment. This results in that it is not expected to issue human instructions to determine the reference position and the position to be tested. This requires collecting environmental data and displacement data as comprehensively as possible. This as comprehensive collection as possible will result in the environmental data containing not only the required environmental measurement information but also other environmental data, and the displacement data containing not only the required device displacement information but also other displacement data. This embodiment aims to solve this problem through an improved solution.
[0089] When the data processing device and the first measuring device establish the near-field communication channel for the first time, the first measuring device starts measuring. When the data processing device and the first measuring device establish the near-field communication channel for the second time, the first measuring device uploads the measurement data, which is equivalent to completing the measurement. The environmental data and the displacement data are synchronously collected data, and the starting time and the ending time of the two are the same. Theoretically, if there is environmental data at a moment, there is at least one displacement data corresponding to it. If there is displacement data at a moment, there is also at least one environmental data corresponding to it.
[0090] After obtaining the environmental data and displacement data, the data processing equipment must process the two in a coordinated manner to achieve the purpose of resolution.
[0091] Specifically, by analyzing the collection process of environmental data and displacement data, it can be found that the displacement data can be composed of three parts. The first part is the front displacement data with displacement state, the second part is the middle displacement data without displacement state, and the third part is the rear displacement data with displacement state. Therefore, the displacement data of each segment can be split by distinguishing the displacement state. A typical method is, first of all, how to judge whether there is relative displacement. It can be judged by comparing the two indicators of relative distance and relative direction. If there is no change in relative distance and relative direction, it can be determined that there is no relative displacement. Otherwise, there is relative displacement. After that, the collection time of environmental measurement information can be obtained from the detection task, such as 30 minutes, and whether there is such a period without relative displacement in the entire displacement data. If so, judge the other moments before and after this period when the relative position is zero, then these moments can form a continuous time period. During this time period, there is no relative displacement, which is the aforementioned middle displacement data. Based on the middle displacement data, processing can be performed, including determining the environmental data corresponding to the acquisition time, calculating the rate of change (derivative) of the environmental data within this acquisition time, and determining the stable interval of the environmental data. The stable interval of the environmental data is the environmental measurement information. If the stable interval of the environmental data exceeds the environmental measurement information, data with the same acquisition time as the environmental measurement information can be selected from the stable interval of the environmental data as the environmental measurement information. After determining the middle displacement data, the displacement data before it is the front displacement data, and the front displacement data is calculated to obtain relative position information. This relative position information indicates the relative position information of the reference position and the position to be measured. After determining the middle displacement data, the displacement data after it is the rear displacement data, and the rear displacement data is calculated to obtain relative position information. This relative position information indicates the relative position information of the position to be measured and the reference position. It can be understood that when the reference position is determined, the relative position information of the front displacement data and the relative position information of the rear displacement data are opposite in relative direction and have the same relative distance.
[0092] There is an improvement example 5 that is a combination of any one of the improvements in the above-mentioned improvement example 1, improvement example 2, improvement example 3 and improvement example 4. Based on improvement example 5, this embodiment provides a specific method for calculating the information of the position of the first device, including establishing a coordinate system with the reference position as a reference coordinate point; determining the first coordinate of the first measuring device in the coordinate system based on the device displacement information of the first measuring device; determining other coordinates of the other measuring devices in the coordinate system based on the device displacement information of the other measuring devices; and determining the information of the position of the first device based on the first coordinate and the other coordinates.
[0093] For example, the first measuring device includes a linear acceleration sensor and an angular velocity sensor. Based on the linear acceleration sensor, the linear acceleration f1 at each moment can be obtained. Based on the angular velocity sensor, the angle ω1 at each moment can be obtained. After obtaining the displacement information of the first device, a three-angle rectangular coordinate system of xyz can be set, and the following formula 1 is obtained:
[0094]
[0095] If the starting time of the device displacement information is the reference position and the ending time is the position to be measured, then in Formula 1, x1 represents the coordinate of the first measuring device on the x-axis when it is arranged at the position to be measured, and cosθ 1xi represents the angle between the angle ω1 and the x-axis at the i-th moment, f 1i represents the linear acceleration f1 at the i-th moment, Δt represents the linear acceleration or the acceleration acquisition time interval, y1 represents the coordinate of the first measuring device on the y-axis when it is arranged at the position to be measured, cosβ 1yi represents the angle between the angle ω1 and the y-axis at the i-th moment, z1 represents the coordinate of the first measuring device on the y-axis when it is arranged at the position to be measured, and cosγ 1zi Represents the angle between the angle ω1 and the z-axis at the i-th moment. Finally, the coordinates (x1, y1, z1) of the first measuring device at the position to be measured with the reference position as the origin can be obtained.
[0096] If the detection also includes a second measuring device, the displacement information of the second device can be calculated in the above manner to obtain the coordinates (x2, y2, z2) of the second measuring device at its position to be measured. Similarly, the coordinates (x2, y2, z2) of the nth measuring device at its position to be measured represented by the displacement information of other devices can be obtained. n ,y n ,z n ).
[0097] Subsequently, according to (x1, y1, z1) and (x n ,y n ,z n ) can be calculated as follows:
[0098]
[0099] In formula 2, l 1n represents the relative distance between the nth measuring device and the first measuring device, A 1xy represents the relative angle projection between the nth measuring device and the first measuring device in the xy plane, A 1xz represents the relative angle projection between the nth measuring device and the first measuring device in the xz plane, A 1yzRepresents the relative angle projection between the nth measuring device and the first measuring device in the yz plane.
[0100] As above, we get P 1n = {l 1n ,A 1xy ,A 1xz ,A 1yz}, where P 1n represents the relative position relationship between the first measuring device and the nth measuring device. Further, by analogy, it can be obtained that P1={P 12 ,P 13 ...P 1n}, P1 represents the information of the position of the first device, which is the set of relative position relationships between the first measuring device and each measuring device. When there are only two measuring devices, P1 = P 12 .
[0101] The above is only an implementation scheme of a rectangular coordinate system. Generally, a spherical coordinate system can also be used, which will not be described again here.
[0102] Correspondingly, the information of the position to be measured can be obtained, p i ={p i1 ,p i2 …… ij}, i≠j, p i represents the information of the i-th position to be measured, p ij Indicates the relative position relationship between the i-th position to be measured and the j-th position to be measured.
[0103] P1 and p i It should be noted that, in the actual detection process, the corresponding relationship between the position to be measured and the measuring device is not known in advance. Therefore, when comparing, P1 and p i Whether the elements in are the same is not affected by the order of the elements, that is, as long as P1 = p i , it indicates that the first measuring device is located at the i-th position to be measured.
[0104] The present embodiment and any one of its Improvement Example 1, Improvement Example 2, Improvement Example 3, Improvement Example 4 and Improvement Example 5 may be improved in combination to provide Improvement Example 6, which determines at least three of the positions to be measured and, correspondingly, determines at least three of the measuring devices.
[0105] In a preferred case of this embodiment, there are three or more positions to be measured, and correspondingly, there are three or more measuring devices. The advantage is that when there are three or more positions to be measured, the key position to be measured (for example, the position to be measured in the center) can often be distinguished from other positions to be measured only by the relative distance relationship, and the same is true for the device position corresponding to the measuring device. At this time, in some cases, only the relative distance between the measuring devices can be measured, and when comparing the information of the first position to be measured with the information of the first device position, only the information of the relative distance can be compared, thereby using less resources and measurement costs to achieve the purpose of solving the technical problem. In some cases, even in combination with the measurement of relative direction, with the help of the characteristics of the relative distance itself, a more reliable judgment can be provided, for example, to judge whether the measuring device is accurately arranged at the position to be measured, or whether there is a deviation in the arrangement.

[0112] The host processing module 110 is signal-connected to the host storage module 120, the first host communication module 141, the second host communication module 142, the host display module 150 and the host input module 160 respectively. Based on the input instruction of the host input module 160, the host processing module 110 retrieves and executes the temperature detection program from the host storage module 120, and projects the interface part of the temperature detection program to the host display module 150 for the user to view.

[0113] It should be noted that the above description is only a hardware architecture form of the test host 100. In some cases, some components in the above description may be integrated together, and some components may be split and integrated into other components. For example, the second host communication module 142 may be directly integrated into the host processing module 110, or a part of the second host communication module 142 is integrated into the host processing module 110, and the other part forms an antenna or a similar structure. It can be understood that these deformations, changes, etc. do not deviate from the expected scope of this embodiment, and do not contribute to the technical problems to be solved by this embodiment. They should belong to equivalent features or equivalent solutions that can be obtained based on this embodiment.
[0114] The data collector 200 can be regarded as the data processing device in the aforementioned embodiment, or as the measuring device in the aforementioned embodiment, or as a partial combination of the aforementioned data processing device and the measuring device, including an acquisition processing module 210, an acquisition storage module 220, an acquisition power supply module 230, an acquisition communication module 240, and an acquisition measurement channel 250, wherein the acquisition measurement channel 250 may include one or more channel interfaces for connecting to the measuring device in the aforementioned embodiment to obtain measurement signals. The acquisition and processing module 210 is configured with a signal processing unit and a digital processing unit. Depending on the measurement signal, if the measurement signal is a digital signal, it can be directly transmitted to the digital processing unit of the acquisition and processing module 210 for processing. If the measurement signal is an analog signal, it is first processed by the signal processing unit and then transmitted to the digital processing unit of the acquisition and processing module 210. The acquisition and processing module 210 and the acquisition and storage module 220 are electrically connected. On the one hand, the acquisition and processing module 210 processes the obtained measurement signal, converts it into measurement data, and stores it in the acquisition and storage module 220. On the other hand, when necessary, the measurement data can also be read from the acquisition and storage module 220 and transmitted to the outside. On the other hand, the acquisition and storage module 220 can also be powered based on the electrical connection. The acquisition communication module 240 is used to communicate with the test host 100. In this example, a data transmission channel is established between the acquisition communication module 240 and the second host communication module 142. Based on the data transmission channel, the measurement data collected by the data collector 200 can be transferred to the test host 100, and the test task can also be issued to the data collector 200 through the test host 100, so that the data collector 200 performs the corresponding measurement process. In some other cases, the acquisition communication module 240 can also establish a data transmission channel with the first host communication module 141. It can be understood that the data transmission channel can be established by direct connection or by means of a network and other communication equipment. The purpose of the acquisition communication module 240 is to realize the communication connection between the data collector 200 and the test host 100. Various wired, wireless communications or other means to achieve this purpose can be regarded as equivalent features or equivalent solutions of this embodiment. The acquisition power supply module 230 is electrically connected to the acquisition processing module 210 and the acquisition communication module 240 respectively, and is used to power the electrical devices in the data collector 200.
[0115] The measuring device has two types: separate and combined. These two types can solve technical problems individually or in combination. To facilitate explanation, this embodiment uses a combined solution for explanation. It can be understood that by splitting some contents in the combined solution, a solution to the technical problem independently can be obtained.
[0116] The temperature sensor may be a thermal resistor, a thermocouple, etc., or other types of sensors with temperature measurement capabilities. It is understandable that a suitable temperature sensor can be selected based on the range, measurement accuracy, etc., and will not be elaborated here.
[0117] The first temperature probe 310 and the first displacement probe 320 are combined to form the aforementioned measuring device in this embodiment.
[0118] The first temperature probe 310 includes a temperature sensor 312. The measuring end of the temperature sensor 312 is located at the measuring end of the first temperature probe 310. The signal end of the temperature sensor 312 is connected to the first probe signal end 311 of the first temperature probe 310. The first probe signal end 311 can output a measurement signal. In the working state, the first probe signal end 311 is connected to the acquisition and measurement channel 250 of the data collector 200.
[0119] The first displacement probe 320 includes an angular velocity sensor 322 and a linear acceleration sensor 323, wherein the angular velocity sensor 322 can measure the angular velocity, and according to the angular velocity information, the information characterizing the angular posture of the first displacement probe 320 can be obtained, and the linear acceleration sensor 323 can measure the linear acceleration, and according to the linear acceleration information, the time processing can be performed to obtain the information characterizing the linear velocity of the first displacement probe 320. It can be understood that, by combining the angular posture and linear velocity information, the displacement information indicating the first displacement probe 320 in a certain very small time period can be obtained, and the motion trajectory of the first displacement probe 320 in the integration time can be obtained by time integration, and then the relative displacement of the first displacement probe 320 can be calculated, including the relative distance and relative direction at two moments. In the working state, the first displacement probe 320 is fixed on the first temperature probe 310, so that the two are structurally integrated, and when the first temperature probe 310 is moved, the first displacement probe 320 also moves the same displacement. In order to transmit the measurement information of the first displacement probe 320 to the outside, the first displacement probe 320 also includes a second probe signal terminal 321. In the working state, the second probe signal terminal 321 is connected to the acquisition and measurement channel 250 of the data collector 200. It can be understood that according to different signal types, the first probe signal terminal 311 and the second probe signal terminal 321 may use the same channel interface or different channel interfaces.
[0120] The second immersive probe 400 includes a temperature sensor 410, an angular velocity sensor 420, a linear acceleration sensor 430, a probe power module 440, a probe processing module 450 and a probe communication module 460, wherein the probe processing module 450 is provided with a power distribution circuit, a storage element and a signal processing element, and the probe processing module 450 is electrically connected to the temperature sensor 410, the angular velocity sensor 420, the linear acceleration sensor 430, the probe power module 440 and the probe communication module 460, respectively. Based on this electrical connection, on the one hand, information signal interaction is realized, and on the other hand, power supply and distribution are realized.
[0121] The detection method of this embodiment is implemented based on the aforementioned test host 100, data recorder 200, first temperature probe 310, first displacement probe 320 and second immersion probe 400. For the convenience of description, the following detection process can generally be used as a part of the detection method. The object to be detected is a temperature box to be detected, and the temperature box to be detected includes a constant temperature chamber 510. Under the working state, the constant temperature chamber 510 can provide a uniform temperature field of a specific temperature (for example, 80°C). In this embodiment, in order to describe the temperature conditions in the constant temperature chamber 510, 9 positions to be measured can be used for description. Specifically, they are the central position to be measured 520 at the center of the constant temperature chamber 510, the first corner position to be measured 521 at the upper left front corner of the constant temperature chamber 510, the second corner position to be measured 522 at the upper right front corner of the constant temperature chamber 510, and the third corner position to be measured 523 at the upper left rear corner of the constant temperature chamber 510. The measuring position 523 is a measuring position 524 at the upper right rear corner of the constant temperature chamber 510, the first measuring position 525 at the lower left front corner of the constant temperature chamber 510, the second measuring position 526 at the lower right front corner of the constant temperature chamber 510, the third measuring position 527 at the lower left rear corner of the constant temperature chamber 510, and the fourth measuring position 528 at the lower right rear corner of the constant temperature chamber 510. The average temperature of each measuring position 520 can be used to evaluate the temperature control accuracy of the constant temperature chamber 510, and the temperature difference of each measuring position 520 can be used to evaluate the temperature control uniformity of the constant temperature chamber 510. Generally, the temperature difference between the center measuring position 520 and the corner measuring position (521-528) can be used to evaluate the temperature gradient of the constant temperature chamber 510, and the temperature difference between different corner measuring positions (521-528) can be used to evaluate the temperature field offset program of the constant temperature chamber 510.
[0122] One of the detection processes, such as Figure 3 Shown, including
[0123] T1. Prepare a measuring device to meet the basic requirements of the test. According to the general requirements for the same type of environmental equipment, prepare at least one first temperature probe 310, at least one first displacement probe 320, and at least one second immersion probe 400. It can be understood that the combination of one first temperature probe 310 and one first displacement probe 320 is equivalent to one second immersion probe 400, and it is necessary to prepare a probe combination that meets the requirements of 9 positions to be tested, that is, a measuring device equivalent to 9 second immersion probes 400.
[0124] T2. Initialize the configuration of the measuring device, including T2.1, T2.2 and T2.3.
[0125] T2.1. Setting the reference position. In this embodiment, in order to facilitate calculation, the same reference position processing method is adopted. Specifically, the vicinity of the first host communication module 141 of the test host 100 is set as the reference position. This setting does not need to be input into the test host 100 or other devices.
[0126] T2.2. Initialize the configuration of the first temperature probe 310 and the first displacement probe 320 so that they start measuring and specify the reference position in their measurement information. Specifically, the first temperature probe 310 and the first displacement probe 320 are fixed to each other so that they become a pair; the first temperature probe 310 and the first displacement probe 320 are respectively connected to the acquisition and measurement channel 250 of the data logger 200; after the connection and establishment of the communication channel are completed, the first temperature probe 310 and the first displacement probe 320 are first placed near the first host communication module 141, and the data logger 200 obtains a startup instruction. This instruction can be set directly in the data logger, or it can be issued and transmitted to the data logger 200 through the measurement host 100. Based on the startup instruction, the data logger 200 starts to collect and measure the acquisition and measurement channel 250.
[0127] In order to more accurately determine the first temperature probe 310 and the first displacement probe 320, the following design can be adopted. After receiving the start-up instruction, the data collector 200 first determines whether there is a collection and measurement channel with a confirmed probe connection status. If so, the collection and measurement channel with a confirmed probe connection status does not participate in the pairing comparison process. Secondly, the pairing comparison process is entered. In one case, reading is performed from each collection and measurement channel 250 with an undetermined probe connection status to see whether there is readable information that is different from the vacant state. Generally speaking, after the probe is connected to the collection and measurement channel 250, if it is a probe in a duplex communication mode or a digital communication mode, the probe information can be directly read. If it is an analog signal probe, the signal fed back to the collection and measurement channel 250 is in the form of a path rather than a break, so that there is an obvious difference between being connected and being vacant. In this case, the difference The readable information in the vacant state can directly determine the newly added probe connected to the acquisition and measurement channel 250. In another case, only the start node is recorded, and the measurement is started for all acquisition and measurement channels 250 with readable data. It can be understood that the above two methods can realize the initialization configuration of the first temperature probe 310 and the first displacement probe 320. After the initialization configuration is completed, the data collector 100 synchronously measures the acquisition and measurement channel 250 where the first temperature probe 310 and the first displacement probe 320 are located, and stores the measurement data to the acquisition storage module 220. This group of data includes a group of temperature data, a group of angular velocity data and a group of linear acceleration data. The starting acquisition time of the three is the same, wherein the starting acquisition position of the angular velocity data and the linear acceleration data corresponds to the aforementioned reference position, i.e., near the first host communication module 141.
[0128] T2.3. Initialize and configure the second immersive probe 400 to start measuring, and specify the reference position in its measurement information. Specifically, the second immersive probe 400 is placed near the first host communication module 141, the probe communication module 460 establishes a near field communication connection with the first host communication module 141, the probe processing module 450 obtains a start instruction, based on the start instruction, the temperature sensor 410, the angular velocity sensor 420, and the linear acceleration sensor 430 start measuring synchronously, and the probe processing module 450 processes and stores the measurement data.
[0129] It can be understood that since the communication range of the near-field communication connection is small and the relative distances and relative directions between the positions to be measured vary greatly, even if near-field communication is established near different adjacent positions of the first host communication module 141, the starting position corresponding to the measurement data recorded by the probe processing module 450 can be used as the reference position, which is the same as the first temperature probe 310 and the first displacement probe 320.
[0130] T3, such as Figure 4 As shown, the first temperature probe 310, the first position probe 320 and the second immersion probe 400 are respectively arranged from the reference position 530 to the corresponding positions to be measured.
[0131] For example, the seventh corner position to be measured 527 is selected, which is one of the nine positions to be measured. In some cases, it can also be other positions to be measured. Then, a combination of a first temperature probe 310 and a first position probe 320 is arranged at the position to be measured. During this operation, combined with the above description, it can be known that the first temperature probe 310 and the first position probe 320 are moved from the reference position 530 to the seventh corner position to be measured 527, and the reference position 530 is determined by the first host communication module 141 of the test host 100. Therefore, a first movement trajectory 541 corresponding to the first temperature probe 310 and the first position probe 320 can be obtained. The first position probe 320 will measure the first movement trajectory 541. The starting end of the first movement trajectory 541 is the reference position 530, and the ending end is the seventh corner position to be measured 527. As a result of this operation, a corresponding relationship between the first temperature probe 310, the first position probe 320 and the seventh corner position to be measured 527 is established at the physical level.
[0132] For another example, a second immersive probe 400 is selected, and then the second immersive probe 400 is arranged at one of the nine positions to be measured, such as the first angle position to be measured 521. Similarly, during this operation, the second immersive probe 400 completes the recording of the second movement trajectory 542. The starting end of the second movement trajectory 542 is the reference position 530, and the ending end is the first angle position to be measured 521. As a result of the operation, a corresponding relationship between the second immersive probe 400 and the first angle position to be measured 521 is established at the physical level.
[0133] After completing the arrangement of all the first temperature probes 310, the first position probes 320, the second immersive probes 400 and the positions to be measured, it can be found that each position to be measured corresponds to either a combination of a first temperature probe 310 and a first position probe 320, or corresponds to a second immersive probe 400, forming a one-to-one correspondence in entity, and the movement trajectory to achieve this correspondence is recorded.
[0134] T4, start the temperature box to be inspected, set the target temperature value (usually also the temperature that needs to be detected), and the temperature box to be inspected begins to control the temperature. When the temperature field temperature provided by the temperature box to be inspected reaches the target temperature value, it lasts for a period of time. During the above process, the first temperature probe 310, the first position probe 320, and the second immersion probe 400 are continuously measuring.
[0135] T5. When the detection conditions of T4 are met, for example, the temperature chamber under inspection has been at the target temperature value for 30 minutes, and sufficient measurement data has been collected, the temperature chamber under inspection is turned off. If high or low temperature is involved, appropriate reverse temperature control can be used to quickly make the ambient temperature in the temperature chamber under inspection reach the daily temperature (20℃-30℃) or nearby.
[0136] T6. The first temperature probe 310, the first position probe 320 and the second immersion probe 400 are taken out of the temperature chamber to be tested, and the test host 100 obtains the data measured by them, namely, the temperature data and displacement data corresponding to each position to be tested.
[0137] Taking the first temperature probe 310 and the first position probe 320 as an example, at the aforementioned time T5, if it is determined that the acquisition task has been completed, since the first temperature probe 310 and the first position probe 320 have been continuously transmitting the measurement data to the data recorder 200, and the data recorder 200 is outside the constant temperature chamber 510, a data channel can be established between the test host 100 and the data recorder 200, and the test host 100 obtains the measurement data from the data recorder 200. It can be understood that corresponding to the same position to be tested, the test host can obtain 1 set of temperature data, 1 set of angular velocity data and 1 set of linear acceleration data. In the best case, the three are synchronously collected. In some cases, there may be deviations due to problems such as acquisition frequency and clock error. In other words, obtaining the measurement data may be carried out at the same time as T5 or later, and taking out the first temperature probe 310 and the first position probe 320 can be carried out at a later time.
[0138] Taking the second immersive probe 400 as an example, after completing T5, the second immersive probe 400 is taken out, and preferably moved to the vicinity of the first host communication module 141. At this time, the second immersive probe 400 and the test host 100 establish a communication connection, and the test host 100 can read the measurement data from the second immersive probe 400. It can be understood that each second immersive probe 400 corresponds to one position to be measured, and thus a corresponding set of temperature data, a set of angular velocity data and a set of linear acceleration data can be obtained.
[0139] T7. The test host 100 can process the relative position information of the position to be tested, each group of angular velocity data and linear acceleration data to obtain the corresponding relationship between the first position probe 320 / the second immersion probe 400 and the position to be tested, and then determine the corresponding relationship between the temperature data and the position to be tested.
[0140] Before executing step T7, although at the physical level, there is a one-to-one correspondence between the first position probe 320 / the second immersive probe 400 and the position to be tested, the test host 100 is unaware of this correspondence. At this time, it is known that the first position probe 320 / the second immersive probe 400 corresponds to a position to be tested, but it is not certain which specific position to be tested the first position probe 320 / the second immersive probe 400 corresponds to.
[0141] T7.1. Calculate the relative position relationship between the first position probes 320 and the second immersion probes 400.
[0142] For a set of angular velocity data and linear acceleration data, calculations are performed. Based on the angular velocity data, its relative direction at each moment can be obtained, and based on the linear acceleration data, its acceleration information at each moment can be obtained. By combining the two, the position change information of the first position probe 320 / the second immersive probe 400 in a certain direction at each moment can be obtained. By combining the position change information at each moment, the total position change information of the first position probe 320 / the second immersive probe 400 can be obtained.
[0143] For angular velocity data and linear acceleration data, first, establish a reference coordinate system, such as a three-dimensional spherical coordinate system, with the reference position as the origin. According to the working principle of the gyroscope, the angle value at each moment can be obtained through its angular velocity data. and θ(t), where represents the azimuth in spherical coordinates, θ(t) represents the elevation in spherical coordinates, and the acceleration value σ(t) at each moment can be obtained based on the linear acceleration data. Taking a set of angular velocity data and linear acceleration data as an example, the velocity change can be obtained as shown in the following formula 3.
[0144]
[0145] In formula 3, represents the azimuth value at each moment, σ i Represents the acceleration value at each moment, represents the elevation angle value at each moment, Δt represents the time interval, and based on the calculation of formula 3, we can get some moments: That is, it indicates that the first position probe 320 / the second immersive probe 400 has not moved at this moment. Furthermore, if it lasts for a period of time, it indicates that the first position probe 320 / the second immersive probe 400 is stable at a certain position. Based on this method, a set of angular velocity data and linear acceleration data are processed to obtain a position stable time period. If there is only one set of position stable time period, the position stable time period corresponds to the first position probe 320 / the second immersive probe 400 being stable at the position to be measured, that is, step T4. If there are two or more sets of position stable time periods, the set with the longest duration is determined as the position stable time period. Subsequently, the position stable time period can be called the middle section, the section before the position stable time period is called the front section, and the section after the position stable time period is called the back section.
[0146] The angular velocity data and linear acceleration data corresponding to the front end are processed as shown in Formula 4.
[0147]
[0148] It can be obtained that when the first position probe 320 / the second immersion probe 400 is stable at the position to be measured, its relative position (spherical coordinates) relative to the reference position, in Formula 4, Φ represents the relative azimuth, Θ represents the relative elevation, and R represents the distance to the reference position.
[0149] Each group of angular velocity data and linear acceleration data is processed as above, that is, the position stabilization time period is determined first, then the front end is determined, and then the angular velocity data and linear acceleration data corresponding to the front end are processed to obtain its relative position relative to the reference position.
[0150] For subsequent further processing, the first set of angular velocity data and linear acceleration data, and the second set of angular velocity data and linear acceleration data are used to calculate the relative positions between different groups. The first set of angular velocity data and linear acceleration data are derived from one of the first position probes 320 / second immersion probes 400 of the aforementioned total of 9 groups, and the second set of angular velocity data and linear acceleration data are derived from another of the first position probes 320 / second immersion probes 400 of the aforementioned total of 9 groups. Using Formula 3 and Formula 4, data Φ1, Θ1, and R1 representing the relative position of the first group and the reference position can be obtained, and data Φ2, Θ2, and R2 representing the second group and the reference position can be obtained. After further processing, the relative position P between the first group and the second group can be obtained. 12 The data is as follows: Formula 5.
[0151]
[0152] Furthermore, based on the above formula 5, the relative position data between the first group and other groups can also be obtained, and finally integrated to obtain the information of the first device position. The so-called first device position information refers to the relative position between the first group and other groups when each first position probe 320 / second immersion probe 400 is located at the position to be measured. It is a set of relative position data between groups, P1={P 12 ,P 13 ,……,P 1n}, and so on for the others.
[0153] It can be understood that this part and the previous part of this embodiment respectively use a three-dimensional rectangular coordinate system and a spherical coordinate system for processing and analysis. The choice of the two coordinate systems needs to be considered based on the actual data collection situation, processing configuration, etc. Generally, the three-dimensional rectangular coordinate system has a relatively small amount of processing for the original data, and a relatively large demand for the calculation of the relative position. The spherical coordinate system has a relatively large amount of conversion processing for the original data, and a relatively small demand for the calculation of the relative position.
[0154] T7.2. Calculate the corresponding relationship between each position to be measured, and then determine the corresponding relationship between the temperature data and the position to be measured.
[0155] With reference to the description in the foregoing embodiment, a distribution model to be tested can be established to describe the distribution of the positions to be tested. Specifically, the distribution model to be tested can include p1, p2, ..., p9, which are used to express the relative position relationship of the first position to be tested, the relative position relationship of the second position to be tested, ..., the relative position relationship of the ninth position to be tested. Further, taking the relative position relationship of the first position to be tested as an example, it can be expressed as p1 = {p 12 ,p 13 ,……}, In the formula, p 12 represents the relative position relationship between the first position to be measured and the second position to be measured, p 13 represents the relative position relationship between the first position to be measured and the third position to be measured, φ 12 represents the azimuth difference between the first position to be measured and the second position to be measured, represents the elevation deviation between the first position to be measured and the second position to be measured, r 12 Indicates the relative distance deviation between the first position to be measured and the second position to be measured.
[0156] Subsequently, by comparing P1 to P9 and p1 to p9, the corresponding relationship between them can be determined. It can be understood that if the first device position corresponds to the first position to be measured, then P1 = p1.
[0157] T8. On the basis of T7, when the correspondence between the first position probe 320 / the second immersion probe 400 and the position to be measured is determined, the correspondence between the temperature data and the position to be measured can be determined. For example, for the first position probe 320, the temperature data collected by the first temperature probe 310 fixed to it is the temperature data of the corresponding position to be measured. For another example, for the second immersion probe 400, the temperature data collected by it is the temperature data of the corresponding position to be measured.
[0158] T9. Processing the temperature data can generate detection data for detecting the temperature box being inspected.
[0159] In some cases, after the aforementioned temperature data is obtained, the detection data is not generated directly, but a first screening is performed according to the aforementioned position stable time period to screen out the temperature data outside the position stable time period.
[0160] In some cases, the temperature data that has been screened once is screened again. The screening method includes first determining the temperature data corresponding to the position to be tested at the center of the temperature field, and retrieving the control status of the entire detection process from the test host 100, including the preset temperature collection time. This is a preset parameter, which usually exists in the detection process. For example, the detection requires collecting 30 minutes of stable temperature field data. Then, at the test host 100, the time distribution of the entire detection process includes temperature control and heating time (for example, 2 hours), stability judgment time (for example, 1 hour), preset temperature collection time 30 minutes, and end time (for example, 30 minutes to 1.5 hours). Combined with the above description, it can be seen that the test host 100 obtains When measuring data, the test host 100 can compare the reference time with the data collector 200 or the first temperature probe 310 or the second immersive probe 400, so as to unify the control time of the test host 100 for the detection process and the measurement data on the same time basis. In this case, it is further possible to check whether the screened temperature data is within the preset temperature acquisition time range. If so, the temperature data within the preset temperature acquisition time is processed, which is the environmental measurement information mentioned above in this embodiment. If not, it indicates that there is a problem with the measurement data, that is, the position stability interval and the preset temperature acquisition time do not match, and it is necessary to re-check the detection situation, analyze the cause of the problem, and re-test.
[0161] The above description is only a preferred embodiment of the present application. For those skilled in the art, the present application may have various modifications and changes. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
