Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a transmission detection method, a transmission track control method, and a transmission track control device. Background Art

[0002] With the increasing prevalence of industrialization, the use of transport tracks for transporting objects is becoming increasingly widespread. In the medical equipment field, during sample testing or reagent processing, transport tracks transport test tube racks loaded with reagents or samples to their target locations. This process typically uses detection signals from photoelectric sensors to determine if the test tube racks are in place and to control the speed of the transport track's motor. In actual applications, due to space limitations for transport track installation, diffuse reflection photoelectric sensors are generally used. Low-sensitivity photoelectric sensors cannot detect test tube racks with low reflectivity, such as black, while high-sensitivity photoelectric sensors are easily interfered with by surrounding photoelectric signals of the same frequency.

[0003] In the prior art, when selecting a photoelectric sensor with high sensitivity, in addition to the photoelectric interference from other photoelectric sensors, it is also susceptible to interference from outside the system, such as natural light or other sudden light signals mixed with the same wavelength, causing the photoelectric sensor to have false sensing problems and make incorrect judgments. Summary of the Invention

[0073] The following will describe the implementation methods of the present invention in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. It should be noted that these specific descriptions are only for ordinary technicians in this field to understand the present invention more easily and clearly, and are not a restrictive interpretation of the present invention; for example, the first and second mentioned in the embodiments of the present invention do not constitute a limitation thereto, but are merely for expressing the serial numbers of multiple identical or similar devices and mechanisms. Ordinary technicians in this field can also readjust these serial numbers for the convenience of expression or in the process of arranging technical solutions; and alternative solutions are described for some mechanisms in different embodiments, and these alternatives can also be applied to other identical or similar devices and mechanisms; and as long as there is no conflict, the various embodiments of the present invention and the various features in each embodiment can be combined with each other, and the technical solutions formed are all within the scope of protection of the present invention.

[0074] The technical solution of the present invention is described in detail below through the accompanying drawings and specific embodiments:

[0075] See Figure 3 The present invention first proposes a conveying device, including a transmission track 10 and a sensing component 20 arranged on the transmission track 10. The transmission track 10 is used to transmit a target object 30, wherein the target object 30 includes but is not limited to a bracket, a cabinet, a packaging box, etc., which can be selected according to the usage scenario. The sensing component 20 includes a transmitting component for transmitting a detection medium toward the transmission track 10 and a detecting component for receiving the detection medium. When the detection medium arrives on the transmission track 10, the transmission direction will be changed due to the influence of the target object 30 on the transmission track 10, resulting in the detection component being able to receive or fail to receive the detection medium.

[0076] In one embodiment, when there is no target object on the transmission track, the detection medium cannot be received by the detection member after being sent to the transmission track because the transmission trajectory deviates from the detection member. When there is a target object on the transmission track, the detection medium is affected by the target object and changes the transmission direction to the detection member, and is detected by the detection member. In another opposite embodiment, when there is no target object on the transmission track, the detection medium can be directly transmitted to the detection member after being sent to the transmission track and received by the detection member. When there is a target object on the transmission track, the detection medium deviates from the receiving direction of the detection member due to the influence of the target object, so that the detection member cannot receive the detection medium. Through the above two embodiments, the sensing component can sense the target object on the transmission track.

[0077] In a specific implementation, the detection medium may preferably be light, and the emitting element is used to emit the detection light toward the target position of the transmission track. After the target object contacts the detection light, the detection light changes the optical path by reflection or refraction, so that the detection light is transmitted through the detection element and thus received by the detection element.

[0078] Taking the example of a diffuse reflection photoelectric sensor as an example, the transmitter and detector are placed on the same side of the transmission track. The transmitter emits detection light toward the transmission track. From a bird's-eye view of the transmission track, the emission range of the detection light has a certain scattering angle on the transmission track. When the detection light within this scattering angle illuminates a target object on the transmission track, the detection light is diffusely reflected from the surface of the target object. A portion of the reflected detection light is detected by the detector and converted into a corresponding electrical signal, thereby sensing the presence of a target object on the transmission track. Figure 1 The emitting element 21 and the detecting element 22 are installed on the same component. The scattering angle of the detection light emitted by the emitting element 21 is a, and the scattered light receiving angle of the detecting element 22 is b. The overlapping area in the extension direction of a and b is the detection area 23 where the target object can be sensed. When the target object reaches the position corresponding to the detection area 23, part of the detection light reflected by the target object will be transmitted to the detecting element 22, thereby being detected by the detection light.

[0079] Alternatively, an optical element capable of reflecting detection light may be provided on the target object. When the target object reaches the target position, the optical element is used to reflect the detection light to the detection element, thereby improving the detection accuracy of the detection element for the detection medium.

[0080] In addition to light, the detection medium may also be sound such as ultrasound or other media that can be used for detection. The fluctuation of the medium can be converted into a detection signal recognized by the device, which is within the scope of the present invention.

[0081] In the prior art, in order to achieve accurate transportation of the target object on the transport track, two or more sensing components may be set in the transport direction. In this case, there may be mis-sensing between the sensing components, resulting in wrong judgment. Figure 2 In the example, when two sensing components appear on the same side of a transmission track, the first emitting element 24a of the first sensing component 24 emits a first detection light toward the transmission track. The emission area of ​​the first detection light is region c, and the receiving area of ​​the detection light by the first detecting element 24b is region d. The second emitting element 25a of the second sensing component 25 emits a second detection light toward the transmission track. The emission area of ​​the second detection light is region f, and the receiving area of ​​the detection light by the second detecting element 25b is region e. In this case, regions c and d overlap to form a first detection region g for detecting target objects, and regions e and f overlap to form a second detection region h for detecting target objects. When a target object is in the first detection region g, the first sensing component 24 is triggered, and when it is in the second detection region h, the second sensing component 25 is triggered. However, it is worth noting in this case that if there is no target object in the first detection area g and the second detection area h, or if part of the first detection light continues to be transmitted along the original emission path after passing through the first detection area g, there is an overlapping area k between the emission area c of the first detection light and the receiving area e of the second detection element 25b at a far position away from the first detection area g and the second detection area h. When there is an object in the overlapping area k, at least part of the first detection light may be reflected along the area e, so that the first detection light is detected by the second detection element 25b. At this time, the first sensing component 24 and the second sensing component 25 may detect the target object at the same time, but the target object is only in the first detection area g, or there may be no target object in both the first detection area g and the second detection area h, but the detection light triggers the second sensing component 25, resulting in a sensing error problem.

[0082] In addition to the problem of sensing errors caused by the above reasons, there may also be the problem that the detection results of the detection element are affected by other light in the environment. Especially for application scenarios with rich detection media, the detection signal detected by the detection element based on the detection medium may also be affected by other detection media other than the non-emitting element.

[0083] Therefore, the present invention further proposes a transmission detection method, which is applied to the above-mentioned transmission device.

[0084] The transmission detection method includes a detection calibration process for the sensing component on the transmission track, which is used to identify whether the detection information of the sensing component is accurate. Figure 10 , the transmission detection method includes:

[0085] S100, controlling the emitting member to emit the detection medium intermittently towards the transmission track in a preset period, wherein the emitting member emits the detection medium in a specified period within the period.

[0086] In the process of controlling the emitting member to emit the detection medium, the emitting period of the emitting member is fixed to give the detection medium a detection period, so that the detection member can identify the detection medium based on the detection period when receiving the detection medium. The specified period within the period is used to give the detection medium emitted by the sensing member a specified label within the period, and the detection member can determine whether the received detection medium is the detection medium emitted by the emitting member of the sensing member according to the specified period.

[0087] In the process of controlling the emitting member to emit the detection medium, the emitting period of the emitting member is fixed to give the detection medium a detection period, so that the detection member can identify the detection medium based on the detection period when receiving the detection medium. The specified period within the period is used to give the detection medium emitted by the sensing member a specified label within the period, and the detection member can determine whether the received detection medium is the detection medium emitted by the emitting member of the sensing member according to the specified period. Figure 3 For example, the detection medium emitted by the emitting member is light, as shown in FIG. 2. Figure 4 In the process of controlling the emitting member to emit the detection medium, the emitting period of the emitting member is fixed to give the detection medium a detection period, so that the detection member can identify the detection medium based on the detection period when receiving the detection medium. The specified period within the period is used to give the detection medium emitted by the sensing member a specified label within the period, and the detection member can determine whether the received detection medium is the detection medium emitted by the emitting member of the sensing member according to the specified period.

[0088] S200, when the sensing member detects that the target object exists in the corresponding detection position on the transmission track, obtaining the first detection information of the target object obtained by the detection member based on the detection medium.

[0089] When the target object is transported to the corresponding detection position on the transport track, the detection medium emitted by the emitter is affected by the target object, and the detection member senses the detection medium, thereby obtaining that the target object exists at the detection position. It should be noted that the sensing member detects the target object at the detection position refers to the triggering state of the sensing member. Even if the corresponding detection position does not exist the target object, if the sensing member is in the triggering state of detecting the target object, it also belongs to the above-mentioned premise. For example, in the implementation process, the detection light is reflected by the surface of the target object, and the detection member receives the reflected detection light to trigger the sensing member to detect the target object. Thus, the triggering state of the sensing member detecting the target object at the corresponding detection position on the transport track is that the detection member receives the detection light, regardless of whether the detection light is received by the detection light due to the reflection of the target object or due to other factors. For another example, the sensing member is in the triggering state by another sensor or in other ways, which is also within the implementation range of the method.

[0090] Under the above conditions, the first detection information of the target object obtained by the detection member according to the detection medium is the detection information fed back by the detection member based on the received detection medium, which includes the receiving period, receiving time and the like of the received detection medium. Taking the above detection light as the detection medium as an example, the detection member is in the triggering state when it receives the detection medium as the starting time, and the first time when it receives the detection medium and the second time when it does not receive the detection medium are obtained. The first time is converted into a corresponding high-level signal, and the second time is converted into a low-level signal, thereby obtaining a time table capable of feeding back the detection information of the detection member. The internal processor of the device obtains the first detection information of the target object detected by the detection member according to the time table. Of course, the first detection information of the target object obtained by the detection member according to the detection medium can also be obtained by other conversion methods, such as converting the detection medium into different electrical signals or other signals to make the internal processor of the device obtain, which is not limited herein.

[0091] S300, validity of the first detection information is confirmed according to the first preset information containing the preset time and the specified period.

[0092] The first preset information can be pre-set in a storage unit of a device for implementing the present transmission detection method and called upon when the transmitter emits the detection medium. The device controls the transmitter to intermittently emit the detection medium toward the transmission track at a preset time period. The first preset information can also be input into the device via an external input method, such as a WiFi, wired network, USB input port, or the like. The input device can include an external controller, an external terminal, or other external device. The device controls the transmitter to emit the detection medium based on the input first preset information. Subsequently, when the detection component obtains first detection information about the target object, the first preset information is used to verify the validity of the first detection information to determine whether it corresponds to the relevant characteristics of the detection medium emitted by the transmitter. If it does not correspond, it indicates that the detection medium received in the first detection information of the detection component is not the detection medium emitted from the transmitter, and the first detection information of the detection component is invalid and constitutes interference information. If the first detection information is confirmed to be valid, it indicates that the first detection information converted by the received detection medium corresponds to the detection medium emitted by the transmitter, but it cannot be determined whether the detection medium is the detection medium emitted by the transmitter in the same sensing component. Therefore, further verification of the detection validity is required.

[0093] S400 , when the first detection information is confirmed to be valid, the transmitting element transmits the detection medium at a confirmation period different from the specified period within the cycle, and obtains second detection information of the target object obtained by the detecting element based on the detection medium within the specified time.

[0094] To further verify the validity of the test, the transmitter's emission information is modified, and after the modification, the validity is verified a second time based on the second detection information obtained by the detection element. Specifically, after the first detection information is confirmed to be valid, the transmitter maintains the same cycle for emitting the detection medium, but modifies the time within the cycle at which the transmitter emits the detection medium to a confirmed period that is different from the specified period.

[0095] Combined with the above Figure 3 For an example, see Figure 4In the period T, after the start time t3 of the low level signal, the signal of the confirmation period control emitter is high level signal, the time of the control emitter continuously emitting the detection medium is the duration t4, after the end of the duration t4, the low level signal state is restored until the end of the period T, wherein the difference between the confirmation period and the specified period can be different arrangement positions in the period T, or different durations, or different caused by the above two cases. Wherein the arrangement positions of the confirmation period and the specified period in the period T are different, which means that from the start time of the period, the start position of the duration t2 in the specified period is different from the start position of the duration t4 in the confirmation period, so that the start time of the emitter emitting the detection medium in the period is different, so that if the detection medium received by the detection piece is the detection medium emitted by the emitter of the same sensing member, the start time of the detection medium received by the detection piece is different from the start time of the first verification. The duration is different, which means that after the emitter starts to emit the detection medium, the duration t2 in the specified period is different from the duration t4 in the confirmation period, so that if the detection medium received by the detection piece is the detection medium emitted by the emitter of the same sensing member, the duration of the detection medium received by the detection piece is different from the duration of the first verification.

[0096] In addition to the above two ways, the number of times of emitting the detection medium by the emitter in the period can be used to distinguish the confirmation period from the specified period, for example, the specified period is one detection medium emission time, and the confirmation period is two detection medium emission times, and the above effects can also be achieved.

[0097] S500, according to the second preset information containing the preset time and the confirmation period, the validity of the second detection information is confirmed.

[0098] After changing the way of emitting the detection medium by the emitter in the period to the confirmation period control, the second detection information obtained by the detection piece is subjected to the second validity confirmation of the present detection calibration process, and the detection information detected by the detection piece is confirmed to be valid information rather than interference information.

[0099] Similar to the first preset information, the second preset information can also be pre-set in a storage unit of the device used to implement the present transmission detection method and invoked when the transmitter emits the detection medium. The device controls the transmitter to intermittently emit the detection medium toward the transmission track at a preset time period. The second preset information can also be input into the device via an external input method, such as a WiFi, wired network, USB input port, or an external controller, or other external device. The device controls the transmitter to emit the detection medium based on the input second preset information. In this embodiment, the second preset information controls the transmitter to emit the detection medium for a confirmation period within an original period, where the preset time period is the cycle time. During validation, the acquired second detection information is verified against the second preset information to determine whether the cycle of the detection medium detected by the transmitter corresponds to the preset time period and whether the detection medium's behavior within the cycle meets the corresponding characteristics specified in the second preset information. This embodiment maintains the preset time period while modifying the specified time period to maintain consistency in the transmitter's output cycle. This also facilitates the subsequent use of multiple sensing components in the device for overall control of the target object on the transmission track.

[0100] S600: When the second detection information is confirmed to be valid, confirm that the target object is in place at the detection position of the sensing component.

[0101] Combined with the description in the aforementioned S500, when the second detection information is confirmed to be valid, it means that after the emission method of the transmitter to the detection medium is changed, the detection information obtained by the detection component based on the received detection medium also changes accordingly, which fully verifies the accuracy of the sensing component in detecting the target object and improves the reliability of the detection.

[0102] In one embodiment, controlling the emission element to intermittently emit the detection medium toward the transmission track at a preset time period includes:

[0103] The interval between the start times of the emission of the detection medium from two adjacent sides of the emission element is controlled to be a preset time.

[0104] In this embodiment, the transmitter emits the detection medium only once in a cycle. Figure 4 The transmitter first emits the detection medium at time k1. After the duration t2 of continuous emission of the detection medium ends, the transmitter stops emitting the detection medium and, after an interval t5, starts emitting the detection medium again with the starting time k2. It then continues emitting the detection medium for duration t2 and after an interval t5, it repeats this process. The time interval between two adjacent starting times k1 and k2 of the transmitter emitting the detection medium is the preset time, which is the cycle time T, where T = t2 + t5.

[0105] Expandably, according to the description of the previous embodiment, when the starting moment of the first emission of the detection medium by the transmitter is determined to be k1, if the detection medium detected by the detection element is the detection medium emitted by the transmitter, then the detection medium can be received at the starting moment k1 and the duration t2 can be detected accordingly. If the moment of the first emission of the detection medium by the transmitter within the cycle is k3 which is different from k1, then the time when the detection element receives the detection medium within the original cycle time T should be correspondingly moved forward or backward by the interval between k1 and k3, that is, the position of the starting moment within the cycle is different.

[0106] The transmitter emits the detection medium during the confirmation period within the period, including:

[0107] When the emitting element starts to emit the detection medium, the interval between the start time and the end time of the emitting element emitting the detection medium within the period range is the designated time.

[0108] Within the cycle range, the interval between the start and end time of the launch of the detection medium by the launcher is the specified time. Figure 4 In the embodiment, the duration is t4. If the detection medium detects the target object, under theoretical conditions, the duration of the detection medium received by the detection element that detects the target object is the same as the duration of the emission of the emission element, that is, the duration t4.

[0109] The sensing components detect the presence of target objects on the transport track including:

[0110] When the detection element captures the detection medium, it is determined that a target object exists on the transmission track.

[0111] In this embodiment, a method of capturing a detection medium is adopted to determine whether the sensing component detects the presence of a target object on the transmission track. As has been described in the above embodiment, since the detection medium is used to detect the target object in this method, when the detection component captures the detection medium, it indicates that the target object may be located at the target position on the transmission track, causing the sensing component to be in a triggered state, thereby tracking the detection information and further judging and verifying the validity of the detection results.

[0112] In one embodiment, the presence of a target object on the transport track is determined by receiving an electrical signal from a detection element. When the detection element receives detection light, which serves as a detection medium, the detection light is converted into an electrical signal by a photoelectric converter. A change in the electrical signal indicates that the detection element has captured the detection light. Subsequent changes in the electrical signal are then used to determine subsequent detection information.

[0113] In step S300 of another embodiment, the first detection information includes capture results of the detection member capturing the detection medium in a plurality of continuous periods after the target object is detected on the transmission track from the sensing member.

[0114] The plurality of continuous periods is two or more, and in the capture results of the first detection information, not only does each period of the plurality of continuous periods capture the detection medium, but also the capture information of the detection member in each period. The number of continuous periods can be reasonably designed according to actual conditions, and the first detection information starts from the first period in which the detection medium is captured. If there is a period in which the detection medium is not captured or the capture result of the detection medium does not meet the requirements in the subsequent target number of periods, the first detection information does not meet the requirements, and the detection member continues to monitor the detection medium and obtain detection information. For example, if the target number is set to 3, if the detection medium is captured in the first period and the capture result meets the requirements, and the detection medium cannot be captured or the capture result does not meet the requirements in the second or third period, it can be determined that the detection information does not meet the requirements, and the detection medium is captured again in the subsequent period. The period in which the capture result meets the requirements is taken as the first period for continuous monitoring. If the detection medium is captured in the three continuous periods and the capture result meets the requirements, it is determined that the first detection information is valid.

[0115] Specifically, the validity of the first detection information is confirmed according to first preset information including a preset time and a specified period, and the first detection information includes capture information of the detection medium in each period after the target object is detected on the transmission track from the sensing member.

[0116] S310, starting from the first period after the target object is detected on the transmission track from the sensing member, it is determined whether the capture result of the detection member capturing the detection medium in each period is valid;

[0117] S320, if the capture result of the detection member capturing the detection medium in the continuous preset number of periods is valid, it is determined that the first detection information is valid;

[0118] S330, if not, the first detection information is determined to be interference information.

[0119] In the first detection information, the capture information of the detection medium in each period is included, and the capture result of the detection medium captured by the detection member in the plurality of continuous periods after the target object is detected on the transmission track from the sensing member includes the duration of the detection medium captured by the detection member in the period range. According to the duration and the specified period in the first preset information for controlling the emission of the detection medium by the emission member, it is verified whether the capture result in the period range corresponds to the detection medium emitted by the emission member.

[0120] Therefore, it is determined whether the capture result of the detection member capturing the detection medium in each period is valid, including:

[0121] determining whether a difference between a duration of the detection medium captured in each cycle and the specified time period is within a valid range;

[0122] If so, the capture result within the cycle is determined to be valid;

[0123] If not, it is determined that the capture result within the cycle is invalid.

[0124] The difference is the allowable range of detection error of the detection component. The first threshold value within the valid range is TX1. If the difference △T is within the valid range, that is, △T≤TX1, it means that the capture result within this period is valid. If not, it means that the capture result is invalid, and the first detection information can be further judged as interference information.

[0125] In step S500 of another embodiment, the second detection information includes a capture result of the detection medium captured by the detection element in a period after the switching moment, and the switching moment is the moment when the detection element emits the detection medium in a confirmation period different from the specified period in the period.

[0126] The capture result of the second detection information includes the capture information of the detection medium by the detection element in the last cycle of the first detection information. Because in the last cycle, after confirming that the first detection information is valid, the detection medium is immediately controlled to be emitted by the emission element according to the confirmation period. Therefore, the duration of the detection medium emitted by the emission element after the switching moment is also within the range of the last cycle.

[0127] Specifically, confirming the validity of the second detection information according to the second preset information including the preset time and the confirmation period includes:

[0128] In a period within a specified time after the switching moment, determining whether the result of the detection element capturing the detection medium within the period is valid, wherein the period within the specified time after the switching moment is the last period in which the first detection information is valid;

[0129] If so, it is determined that the second detection information is valid;

[0130] If not, it is determined that the second detection information is interference information.

[0131] See Figure 4The second detection information is also obtained by the detection element. It is the duration of the detection medium obtained during the preset time immediately following the last cycle of the first detection information after the transmitter switches its transmission mode. The confirmation period t4 is located later than the designated period t2 within the last cycle T. The switching time k3 is set between the designated period t2 and the confirmation period t4. Therefore, after the switching time, the designated period t2 and the confirmation period t4 can be detected by the detection element in the same cycle, i.e., the last cycle T. The designated period t2 is captured in the first detection information, and the confirmation period t4 is captured in the second detection information. Therefore, by comparing the duration of the confirmation period in the second detection information with the confirmation period in the second preset information used to control the transmitter to emit the detection medium, it is verified whether the capture result within the cycle range corresponds to the detection medium emitted by the transmitter.

[0132] Therefore, determining whether the detection element's capture result of the detection medium is valid includes:

[0133] determining whether the difference between the duration of the captured detection medium and the confirmation period is within a valid range;

[0134] If so, the capture result is determined to be valid;

[0135] If not, the capture result is determined to be invalid.

[0136] This difference is the permissible range of detection error for the detection component, and the second threshold within the valid range is TX2. If the difference ΔT is within the valid range, that is, ΔT ≤ TX2, the capture result within this period is valid. If not, the capture result is invalid, and the first detection information can be further determined to be interference information. In this embodiment, the second threshold is set to the same value as the first threshold, but it can also be set to a different value depending on the actual situation, and this is not limited here.

[0137] In addition, a similar method as the first detection information can be used to determine whether the capture results in each of a plurality of consecutive cycles meet the requirements. The plurality of consecutive cycles can be two or more. The capture results of the second detection information include not only whether the detection medium is captured in each of the plurality of consecutive cycles, but also the capture information of the detection element in each cycle. The number of consecutive cycles can be reasonably designed based on actual conditions. The second detection information begins with the first cycle after the switching moment. If the target number of subsequent cycles is not reached and there is a cycle in which the detection medium is not captured or the capture result of the detection medium does not meet the requirements, then the second detection information does not meet the requirements and is determined to be interference information.

[0138] It should be noted that when judging whether the capture result in each cycle is valid, the cycle within the specified time after the switching moment is a cycle continuous with the last cycle when the first detection information is valid, that is, the first cycle of the first capture detection medium after the switching moment should be connected to the last cycle when the first detection information is valid. If the capture result of the detection medium in the first cycle does not meet the requirements, the second detection information can be directly judged as interference information. The validity verification condition is that when the first detection information is judged to be valid, the calibration process of the transmitter emitting the detection medium at a confirmation period different from the specified period is immediately executed within the cycle, so that the detection element verifies the relevant characteristics of the detection medium emitted by the transmitter after the switching moment in the first cycle after the last cycle of the first detection information. This can effectively ensure the validity of the verification and avoid the problem of calibration error caused by the switching moment not being continuous with the valid first detection information.

[0139] See Figure 11 In a third aspect, the present invention further proposes a transmission track control method, which is applied to a conveying device comprising at least two sensing components and includes the transmission detection method proposed in the embodiment of the second aspect of the present invention, wherein the transmission track control method includes:

[0140] S1, controls the transmission track to transmit the target object along the specified transmission path;

[0141] S2, performing a detection calibration process for each sensing component on a designated transmission path of a target object, wherein the period of emission of the detection medium by the emitting element in each sensing component is synchronized, but the duration of the designated time period during which the emitting element of each sensing component emits the detection medium within the period range is different;

[0142] S3, when it is confirmed that the target object is transferred to the detection position of the last sensing component on the designated transfer path, the transfer process of the target object on the designated transfer path is completed.

[0143] This method is applied to the multi-segment operation control process of the target object on the transmission track, and the transmission of the target object is controlled by multiple sensing components. At least one sensing component is set on each section of the transmission track to control the transmission, reversal or stop of the target object.

[0144] During the control process of the transmission track control method, the start signal for transmitting the target object can be initiated by an operation panel or an internal control program, and a transmission signal is sent to the controller of the transmission track to enable the transmission track to transmit the target object. During the transmission process of the target object, step S200 is executed. While the target object is being transmitted, a detection calibration process of each sensing component is performed to ensure the effectiveness of the sensing component detection and to confirm the effective transmission of the target object on the transmission track.

[0145] In this embodiment, the detection medium emitted by each sensing component is synchronized in periodicity and easy to implement. The emitted detection medium is distinguished by the different durations of specified time periods within the periodic range. Therefore, during the respective detection calibration processes of each sensing component, if the duration of the first detection information obtained is different from the corresponding specified time period, it means that the received detection medium is an interference signal, which may be the detection medium emitted by the emitting element of another sensing component, or some other interference signal.

[0146] This embodiment can be set to the following control mode. During the control process of the transmission track control method, if the detection calibration process of the sensing component on a certain section fails, the target object is prevented from entering the next section. The sensing components on each section detect the target object through the validity detection calibration process until the target object passes the validity calibration detection process at the detection position of the last sensing component on the specified transmission path, indicating that the transmission process of the target object on the specified transmission path has been completed.

[0147] In one embodiment, the designated time periods of the induction components on the designated transmission path are staggered and do not overlap within the cycle range. That is, within the same cycle range, the designated time periods of the induction components do not have overlapping parts, and are arranged alternately or adjacently in the cycle. Figure 9 The embodiment shown in is illustrated, the designated time periods of the five sensing components are respectively the first time period, the second time period, the third time period, the fourth time period and the fifth time period, and these five time periods are arranged in sequence in a cycle, so that when the detection component captures the detection medium, it can judge whether the detection medium corresponds to the detection medium of the emission component of the same sensing component based on the appearance time of the designated time period of the original sensing component within the cycle; if the emission moment of the emission component is inconsistent with the capture moment of the detection component or the difference is large, it can be judged in advance that the captured detection medium is not the detection medium emitted by the matching emission component.

[0148] It can be further extended to ensure that the time periods and the specified time periods are staggered and do not overlap within the cycle range. Figure 9 The length of the confirmation period is different from the length of each specified period, and the arrangement position in the cycle is also different. Therefore, the sensing component has the dual characteristics of different capture time and duration after switching to the confirmation period. The device can effectively identify the emitted detection medium after it is captured by the detection component.

[0149] In addition, the transmission track control method further includes:

[0150] S4, after each sensing component completes the detection calibration process of its corresponding detection position, when the sensing component detects that the target object leaves its corresponding detection position, it waits for a specific time and then controls the emitting element of the sensing component to stop emitting the detection medium.

[0151] This configuration can reduce resource waste caused by the continuous operation of the sensing component. The specific waiting time is set to prevent the target object from completely leaving the road section. If the target object is redetected within the specific time, the sensing component is controlled to continue detection until the target object leaves, or a detection error is executed. The sensing component can detect that the target object has left its corresponding detection position based on whether the detection member of the sensing component receives the detection medium. If the detection member no longer receives the detection medium, it indicates that the target object has left. Alternatively, if the detection information of the detection medium received by the detection member does not meet the validity verification of the first detection information, it indicates that the target object has left.

[0152] In some embodiments, the transmission track control method uses pulse signals to control the transmitters of each sensing component to emit a detection medium at corresponding designated time periods within a cycle range. The pulse widths corresponding to the detection medium emission at each designated time period within the cycle range are different, and the pulse bands corresponding to the detection medium emission are staggered. The pulse signal method is easy to control, and can achieve transmission and reception of the detection medium using only high and low voltage levels, which is simple and effective.

[0153] See also Figure 6 The transport track is used to transport the carriage. When the detection position of at least two sensing components is the same as the detection position, and the carriage is at the detection position, each sensing component performs a detection and calibration process on the transport track in order of priority. The detection position refers to the position at which the target object can be simultaneously detected by at least two sensing components due to its own length, width, or height, that is, the detection position of the at least two sensing components coincides with the detection position. In this case, the detection and calibration process of each of the at least two sensing components needs to be performed according to the priority to avoid affecting the detection and calibration process of the sensing component of the higher priority object due to the early execution of the detection and calibration process of the lower priority object, resulting in detection errors.

[0154] The detection and calibration process of each sensing component on the transmission track is performed in order of priority, including:

[0155] When there is only one carriage on the transport track, the sensing component at the front end of the transport direction has a higher priority than the sensing component at the rear end of the transport direction, and the detection and calibration process of the sensing components on the transport track is performed in sequence;

[0156] When the transmission track has multiple brackets, each sensing component performs the detection and calibration process of the sensing component on the transmission track in sequence along the transmission direction.

[0157] When there is a bracket on the transmission track, the detection and calibration process of the sensing component at the front end of the transmission direction should be performed first. This is because during the detection process of the sensing component, the bracket may be continuously moving on the transmission track. If the detection and calibration process is performed first with the sensing component at the rear end, it may leave the detection range of the sensing component in advance during the detection and calibration process, and affect the subsequent detection and calibration process of the sensing component in the subsequent process, resulting in the inability to complete the detection and calibration process. Therefore, the priority of the detection and calibration process of the sensing component is set. When the sensing component at the front end senses the target object, the detection and calibration process can be performed first to effectively confirm whether the bracket is in the detection position.

[0158] Similarly, when there are multiple brackets on the transmission track, the detection and calibration process of the sensing component at the front end of the transmission direction should also be performed first. If the detection and calibration process is performed first with the sensing component at the rear end, it is possible that the bracket will leave the detection range of the sensing component early during the detection and calibration process, and the subsequent bracket will enter the detection position of the sensing component, thereby affecting the detection and calibration process of the sensing component, and may affect the subsequent detection and approval process of the sensing component in the subsequent process. Therefore, the priority of the sensing component in executing the detection and calibration process is set. When the sensing component at the front end senses the target object, the detection and calibration process can be performed first to effectively confirm whether the bracket is in the detection position.

[0159] In addition, according to the priority, the position of the designated time period of each sensing component within the cycle range is also sorted according to the priority, that is, the designated time period of the sensing component with high priority is located at the front end, and the detection medium can be preferentially emitted at the beginning of the cycle to detect the target object, and in the subsequent detection process, the detection results of the sensing component with high priority are given priority to ensure the orderly operation of the transmission track.

[0160] The following describes the operation of a single bracket on a single track, a single bracket across tracks, and multiple brackets across tracks as examples.

[0161] Single carriage single track operation

[0162] See Figure 3 and Figure 5 The transmission track 10 has a transmission section, in which an induction component 20 is arranged. The emitting component of the induction component 20 emits high and low level signals with a period of TS according to the received pulse information, wherein the pulse width of the high level in the period TS is T1, and the period of the corresponding emitting component emitting the detection medium is TS, and the specified time period of emitting the detection medium in the period TS is T1.

[0163] Then, in the detection calibration process of the sensing member 20, when the sensing member 20 detects the target object 30 in the first detection information validity confirmation, it is determined whether the detection information fed back by the detection member receiving the detection medium is a period TS and a pulse width T1. If the detection information fed back by the detection medium is detected to have a pulse width within the effective range in the continuous M periods, i.e., T1-TX1≤L1≤T1+TX1, L1 being the actual detection value, it is determined that the first detection information detected by the detection member is valid, otherwise the first detection information is an interference signal. Figure 3

[0164] Then, in the subsequent second detection information validity confirmation, after it is determined that the first detection information is a valid signal, the pulse width is switched to TK, and the control of the emitting member is controlled to emit the detection medium for a duration of the confirmation period TK. In the specified time Tn thereafter, when the detection member captures the pulse width converted by the detection medium within the effective range, i.e., TK-TX2≤LK≤TK+TX2, LK being the actual detection value, it is determined that the second detection information of the sensing member 20 for the tray 31 is valid information.

[0165] After it is determined that the second detection information is valid information according to the sensing member 20, the transmission track 10 is controlled to stop transmitting the tray 31, and the tray 31 is transmitted to the position. In this embodiment, the transmission track 10 can be driven by a motor, and the motor is controlled to stop or transmit the transmission track 10.

[0166] Single-tray cross-track operation

[0167] Referring to Figure 6 and Figure 7 , the transmission track has two transmission sections, the first sensing member 24 is arranged in the first transmission section 11, and the second sensing member 25 and the third sensing member 26 are arranged in the second transmission section 12. When a single tray 31 is transmitted on the transmission track, due to the length of the tray 31 itself, there is a possibility that the first sensing member 24 and the second sensing member 25 work at the same time, i.e., the signals emitted by the first sensing member 24 and the second sensing member 25 can detect the tray 31 at the same time, while the remaining sensing members do not detect the tray 31. In this case, the priority of the second sensing member 25 to be reached is higher than that of the second sensing member 24 to be left, and the priority of the third sensing member 26 is set to be the lowest because it is not in the working state of sensing the tray 31, so the detection calibration process of the second sensing member 25 is preferentially performed.

[0168] ​Before the bracket 31 reaches the second sensing component 25, the emitting element of the second sensing component 25 emits high and low level signals with a period of TS according to the received pulse information, wherein the pulse width of the high level within the period TS is T2, and the period for the corresponding emitting element to emit the detection medium is TS, and the specified time period for emitting the detection medium within the period TS is T2.

[0169] When confirming the validity of the first detection information, when the sensing component detects the bracket 31, it is determined whether the detection information fed back by the detection medium received by the detection component has a period TS and a pulse width T2. If the pulse width of the detection information fed back by the detection medium is detected to be within the valid range within M consecutive periods, that is, T2-TX1≤L2≤T2+TX1, and L2 is the actual detection value, then the first detection information detected by the detection component is determined to be valid; otherwise, the first detection information is an interference signal.

[0170] When the validity of the second detection information is subsequently confirmed, after the first detection information is judged to be a valid signal, the control pulse width is switched to TK, and the duration of the control emission element to emit the detection medium within the cycle is the confirmation period TK. Within the specified time Tn thereafter, when the pulse width converted by the detection element capturing the detection medium is within the valid range, that is, TK-TX2≤LK≤TK+TX2, LK is the actual detection value, then the first detection information of the sensing component for the bracket 31 is judged to be valid information.

[0171] When the second detection information sensed by the second sensing component 25 is valid, the transmission track is controlled to decelerate and pass through the second sensing component 25 at a reduced speed.

[0172] After completing the detection calibration process of the second sensing component 25, the detection calibration process of the first sensing component 24 is executed. The pulse width of the first sensing component 24 is T1 and the period is TS. If the first sensing component 24 detects that the bracket 31 has left its detection position, it maintains the detection position for a specific time T0, and then controls the emission element of the first sensing component 24 to stop emitting the detection medium.

[0173] Thereafter, during the detection and calibration process of the third sensing component 26 , the pulse width of the third sensing component 26 is T3 and the period is TS. When the detection information of the third sensing component is determined to be valid during the detection and calibration process, the transmission track is controlled to stop running and it is determined that the bracket 31 has been transferred to its proper position.

[0174] Multiple brackets running across tracks

[0175] See Figure 8 and Figure 9, there are three transmission sections on the transmission track, the first transmission section 11 is provided with a first sensing component 24, the second transmission section 12 is provided with a second sensing component 25 and a third sensing component 26, and the third transmission section 13 is provided with a fourth sensing component 27 and a fifth sensing component 28. When the bracket 31 is present on the first transmission section 11, the second transmission section 12 and the third transmission section 13 at the same time, there is a possibility that the five sensing components will work at the same time. At this time, the priority of the detection and calibration process of the five sensing components is judged in turn, that is, the sensing components are sorted according to the order in which they detect the bracket 31. Figure 9 , the second sensing member 25 > the third sensing member 26 > the fourth sensing member 27 > the fifth sensing member 28 > the first sensing member 24, that is, the second sensing member 25, the third sensing member 26, the fourth sensing member 27 and the fifth sensing member 28 will detect the bracket 31 first in sequence, and because the bracket 31 is not in the detection position of the first sensing member 24, the priority of the first sensing member 24 is set to the lowest.

[0176] Therefore, before the detection medium is detected, each sensing component is controlled to emit the detection medium according to the pulse information with a period of TS and pulse widths of T1, T2, T3, T4, and T5 respectively, where T1, T2, T3, T4, and T5 are not the same, which are equivalent to the ID numbers of the first sensing component 24, the second sensing component 25, the third sensing component 26, the fourth sensing component 27, and the fifth sensing component 28, and their respective detection and calibration processes are performed in order of priority until the bracket 31 is transferred to its place.

[0177] The first sensing member 24 can be configured as a first in-position sensing member, the second sensing member 25 as a deceleration sensing member, the third sensing member 26 as a second in-position sensing member, the fourth sensing member 27 as a deceleration sensing member, and the fifth sensing member 28 as a third in-position sensing member. Furthermore, multiple sensing members can be provided, each of which performs a corresponding action when it detects that the carriage 31 has arrived at a corresponding transfer position, thereby achieving orderly control of the entire conveying device.

[0178] In the fourth respect, see Figure 12 The present invention provides a transmission track control device 40, which is applied to the transmission device of the first embodiment, including:

[0180] The execution unit 42 is used to control the transmission path to transmit the target object and control the transmitting element of each sensing component to emit the detection medium;

[0181] The processing unit 43 is used to control the execution unit so that the emitting component of the sensing component intermittently emits the detection medium toward the transmission track at a preset time period, confirm whether the target object is transmitted to the detection position corresponding to the sensing component based on the first preset information and the second preset information and the first detection information and the second detection information obtained by the detection unit, and control the execution unit to stop transmission or execute the next action command based on the confirmation result.
