[0002] With the continuous popularization of industrialization, the application of transmission tracks for transporting objects is becoming more and more widespread. In the field of medical equipment, when performing sample testing or reagent processing, the transmission track transports the test tube rack loaded with reagents or samples to the target position. In this process, the detection signal of the photoelectric sensor is usually used to determine whether the test tube rack is in place and control the speed of the motor rotation of the transmission track. In actual application, due to the limitation of the installation space of the transmission track, diffuse reflection photoelectric sensors are generally used. For low-sensitivity photoelectric sensors, they cannot identify test tube racks with low reflectivity such as black, while high-sensitivity photoelectric sensors are easily interfered by the 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 band, causing the photoelectric sensor to have false sensing problems and make wrong judgments. Summary of the invention

DETAILED DESCRIPTION

[0035] The following will describe the implementation methods of the present invention in detail in combination with the accompanying drawings and embodiments, 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, rather than 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 only 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 in 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 protection scope of the present invention.

[0036] The technical solution of the present invention is described in detail below through the accompanying drawings and specific embodiments: See also 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.

[0037] 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 and received by the detection member after being sent to the transmission track, and 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 implementations, the sensing component can sense the target object on the transmission track.

[0038] 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.

[0039] Taking the case of a diffuse reflection photoelectric sensor as the sensing component, the transmitter and the detector are arranged on the same side of the transmission track. The transmitter emits detection light toward the transmission track. From the top 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 the scattering angle irradiates the target object on the transmission track, the detection light has a diffuse reflection effect on the surface of the target object, and a part of the reflected detection light is detected by the detection component 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 that can sense the target object. When the target object arrives at 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.

[0040] In an expandable manner, 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 element's receiving accuracy of the detection medium.

[0041] 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, all of which are within the scope of the present invention.

[0042] In the prior art, in order to achieve accurate transportation of the target object on the transmission track, two or more sensing components may be set in the transportation direction. In this case, there may be mis-sensing between the sensing components, resulting in wrong judgment. Figure 2In the embodiment, when two sensing components appear on the same side of the transmission track, the first emitting element 24a of the first sensing component 24 sends a first detection light toward the transmission track, and the emission area of ​​the first detection light is area c, and the receiving area of ​​the detection light of the first detection component 24b is area d. The second emitting element 25a of the second sensing component 25 sends a second detection light toward the transmission track, and the emission area of ​​the second detection light is area f, and the receiving area of ​​the detection light of the second detection component 25b is area e. In this case, area c and area d form a first detection area g for detecting the target object at a mutually overlapping position, and area e and area f form a second detection area h for detecting the target object at a mutually overlapping position. When the target object is in the first detection area g, the first sensing component 24 can be triggered, and when it is in the second detection area h, the second sensing component 25 can be 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 the far end 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 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 is no target object in 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.

[0043] 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.

[0044] Therefore, the present invention further proposes a transmission detection method, which is applied to the above-mentioned transmission device.

[0045] 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. Fig.10 , the transmission detection method includes: S100, controlling the transmitting element to intermittently transmit the detection medium toward the transmission track with a preset time as a cycle, wherein the transmitting element transmits the detection medium within a specified time period within the cycle range.

[0046] When controlling the transmitter to transmit the detection medium, the transmission cycle of the transmitter is fixed to give the detection medium a detection cycle, so that when the detection medium is received, the detection medium is identified based on the detection cycle. The specified time period within the cycle range is used to give the detection medium emitted by the sensing component a specified label within the cycle range, and the detection component determines whether the received detection medium is the detection medium emitted by the transmitter of the sensing component based on the specified time period.

[0047] by Figure 3 For example, the detection medium emitted is light. Figure 4 When controlling the transmitter to emit the detection medium, the transmitter is controlled by high and low level signals. When the signal transmitted to the transmitter is a high level signal, the transmitter is controlled to emit the detection medium. When the signal transmitted to the transmitter is a low level signal, the transmitter is controlled to cancel the emission of the detection medium. Therefore, within the range of cycle T, after the start time t1 of the low level signal, the signal of the transmitter is controlled to be a high level signal in the specified time period t2, and the duration of controlling the transmitter to emit the detection medium is t2. After the specified time period t2 ends, the low level signal state is restored until the end of the cycle T. Therefore, due to the different arrangement and duration of the low level signal and the high level signal in the cycle T, the resulting detection medium has different manifestations in the cycle T, and because the time interval between the emission and reception of light is very short and negligible, the emission cycle of the transmitter and the reception cycle of the detection element should be synchronized. On this basis, it can be judged according to the design changes of the specified time period in the cycle.

[0048] S200, when the sensing component detects that there is a target object at a corresponding detection position on the transmission track, first detection information of the target object obtained by the detection component according to the detection medium is obtained.

[0049] When the target object is transmitted to the corresponding detection position on the transmission track, the detection medium emitted by the transmitting element will be affected by the target object, and thus sensed by the detecting element, and it is known that the target object exists at the detection position. It should be noted that the detection of the presence of the target object at the detection position by the sensing component refers to the triggering state of the sensing component. Even if the target object does not exist at the corresponding detection position, if the sensing component is in the triggering state of detecting the target object, it also falls within the above premise. For example, during the implementation process, the detection light will be reflected by the surface of the target object, and the detection element receives the reflected detection light and triggers the sensing element to detect the sensing state of the target object. Therefore, the triggering state when the sensing element detects the presence of the target object at the corresponding detection position on the transmission track is the detection element receiving the detection light, regardless of whether the detection light is received by the detection light due to reflection of the target object or due to other factors. For another example, the sensing element is in a triggered state by setting up a sensor for triggering or in other ways, which is also within the scope of implementation of the present method.

[0050] Under the above conditions, the first detection information of the target object obtained by the detection part based on the detection medium is the detection information fed back by the detection part based on the received detection medium, and the detection information includes the receiving period and receiving time of the received detection medium. Continuing with the above detection light as the detection medium as an embodiment, the detection part receives the detection medium and puts the sensing component in a triggering state as the starting moment, and starts to obtain the first moment when the detection part receives the detection medium and the second moment when the detection medium is not received, and converts the first moment into a corresponding high-level signal and the second moment into a low-level signal, thereby obtaining a timetable that can feed back the detection information of the detection part, and the internal processor of the device obtains the first detection information of the target object detected by the detection part according to the timetable. Of course, the first detection information of the target object obtained by the detection part based on the detection medium can also be obtained through other conversion methods, such as converting the detection medium into an electrical signal or other signal different from the above so that the internal processor of the device can know it, which is not limited here.

[0051] S300, confirming the validity of the first detection information according to the first preset information including the preset time and the specified time period.

[0052] The first preset information can be preset in advance in the storage unit of the device for implementing the transmission detection method, and is called when the transmitter emits the detection medium. The device controls the transmitter to intermittently emit the detection medium toward the transmission track with a preset time as a period. The first preset information can also be input into the device through external input. The input method can include input ports such as WiFi, wired network, USB, etc. The input device can include an external controller, an external terminal and other external devices. The device controls the transmitter to emit the detection medium based on the input first preset information. When the first detection information about the target object is obtained by the detection component later, the first preset information is used to verify the validity of the first detection information to determine whether the first detection information corresponds to the relevant characteristics of the detection medium emitted by the transmitter. If not, it means 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 is interference information. If the first detection information is confirmed to be valid, it means 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, so it is necessary to further verify the validity of the detection.

[0053] S400, when the first detection information is confirmed to be valid, the emitting element emits the detection medium in a confirmation period different from the specified period within the cycle, and obtains second detection information on the target object obtained by the detection element based on the detection medium within the specified time.

[0054] When further verifying the validity of the detection, the emission information of the emitter is changed, and the validity is verified for the second time based on the second detection information obtained by the detection element after the change. Specifically, when the first detection information is confirmed to be valid, the cycle of the emitter emitting the detection medium is kept the same, and the time of the emitter emitting the detection medium within the cycle is changed, and the time is changed to a confirmed period different from the specified period.

[0055] Combined with the above Figure 3 For an example, see Figure 4, within the range of cycle T, after the start time t3 of the low-level signal, the signal of the transmitter is controlled to be a high-level signal during the confirmation period, and the transmitter is controlled to continuously transmit the detection medium for a duration of t4. After the duration t4 ends, the low-level signal state is restored until the end of the cycle T, wherein the difference between the confirmation period and the specified period may be a different arrangement position within the range of cycle T, or a different duration, or may be caused by the above two situations. Among them, the difference in the arrangement position of the confirmation period and the specified period within the range of cycle T means that, calculated from the start time of the cycle, the starting position of the duration t2 in the specified period is different from the starting position of the duration t4 of the confirmation period, thereby causing the transmitter to start emitting the detection medium at a different start time within the cycle, so that if the detection medium received by the detection member is the detection medium emitted by the transmitter of the same sensing component, the starting time of the detection medium received by the detection member is different from the starting time of the first verification. Different duration means that after the transmitter starts to emit the detection medium, the duration t2 in the specified time period is different from the duration t4 in the confirmation time period, so that if the detection medium received by the detector is the detection medium emitted by the transmitter of the same sensing component, the duration of the detection medium received by the detector will be different from the duration during the first verification.

[0056] In addition to the above two methods, the confirmation period can also be distinguished from the specified period by utilizing the number of times the transmitter emits the detection medium within a cycle. For example, the specified period is the detection medium emission time once, and the confirmation period is the detection medium emission time twice, etc., which can also achieve the above effect.

[0057] S500: Confirm the validity of the second detection information according to the second preset information including the preset time and the confirmation period.

[0058] After the mode of emitting the detection medium by the emitting element within the cycle is changed to be controlled by the confirmation period, a second validity confirmation of this detection calibration process is performed for the second detection information obtained by the detection element to confirm that the detection information detected by the detection element is valid information rather than interference information.

[0059] Similar to the first preset information, the second preset information can also be preset in advance in the storage unit of the device for implementing the transmission detection method, and is called when the transmitter emits the detection medium. The device controls the transmitter to intermittently emit the detection medium toward the transmission track with a preset time as a cycle. It can also be input into the device through external input. The input method may include WiFi, wired network, USB and other input ports, etc. The input device may include an external controller, an external terminal and other external devices, etc. The device controls the transmitter to emit the detection medium based on the input second preset information. In this embodiment, the second preset information is used to control the transmitter to emit the detection medium in the original cycle with the preset time as the cycle time to confirm the period. When confirming the validity, the second detection information obtained is verified according to the second preset information to determine whether the cycle of the detection medium detected by the detection element is the cycle of the preset time, and whether the performance of the detection medium in the cycle meets the corresponding characteristics in the second preset information. In this embodiment, the specified period is changed while retaining the preset time as the cycle to maintain the consistency of the output cycle of the transmitter, and it is also beneficial for the subsequent device to set multiple sensing components to control the overall control of the target object on the transmission track.

[0060] S600, when the second detection information is confirmed to be valid, confirm that the target object is transmitted to the detection position of the sensing component.

[0061] Combined with the description in the aforementioned S500, when the second detection information is confirmed to be valid, it means that after changing the emission mode of the emission component to the detection medium, 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.

[0062] In one embodiment, controlling the emission element to intermittently emit the detection medium toward the transmission track with a preset time as a period includes: 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.

[0063] In this embodiment, the transmitting element transmits the detection medium only once in a cycle, see Figure 4 , the starting time of the first emission of the detection medium by the emitter is k1, after the duration t2 of the continuous emission of the medium ends, the emitter stops emitting the detection medium, and after the interval t5, the emitter re-emits the detection medium and the starting time is k2, and then continues to emit again after the interval t5 for the duration t2, and repeats this process. At this time, the time interval between the two adjacent starting times k1 and k2 of the emission of the detection medium by the emitter is the preset time, which is the cycle time T, T=t2+t5.

[0064] Expandably, according to the description of the previous embodiment, when the starting time 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 time k1 and detected for a duration t2. If the time when the transmitter first emits the detection medium 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 time within the cycle is different.

[0065] The transmitter within the cycle range emits the detection medium during the confirmation period, including: When the emitting element starts to emit the detection medium, the interval time between the start time and the end time of the emitting element emitting the detection medium within the cycle range is the designated time.

[0066] Within the cycle range, the interval between the start time and the end time of the launch of the detection medium by the launcher is the specified time. Figure 4 In the embodiment, it is shown as duration t4. If the detection medium detects the target object, under theoretical conditions, the receiving duration of the detection medium detected by the detection element is the same as the transmitting duration of the transmitting element, that is, duration t4.

[0067] The sensing components detect the presence of target objects on the transport track including: When the detection element captures the detection medium, it is determined that there is a target object on the transmission track.

[0068] 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 described in the previous embodiment, since the detection medium is adopted 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 of the transmission track, so that the sensing component is in a triggered state, thereby tracking the detection information and further judging and verifying the validity of the detection result.

[0069] In a specific embodiment, receiving an electrical signal from the detection element is used as a capture condition to determine the presence of a target object on the transmission track. When the detection element receives the detection light as a detection medium, the detection light converts the optical signal into an electrical signal under the action of the photoelectric converter. When the device detects a change in the electrical signal, it indicates that the detection element has captured the detection light, and the subsequent detection information of the detection element is obtained according to the subsequent change state of the electrical signal.

[0070] In step S300 of another embodiment, the first detection information includes the capture results of the detection medium captured by the detection member within a plurality of consecutive cycles after the sensing component detects the target object on the transmission track.

[0071] The continuous multiple cycles are two or more than two. In the capture result of the first detection information, not only the detection medium is captured in each cycle of the continuous multiple cycles, but also the capture information of the detection element in each cycle. The continuous number of cycles can be reasonably designed according to the actual situation. The first detection information starts from the first cycle when the detection medium is captured. If the target number of cycles is not reached later, there is a cycle in the middle where the detection medium is not captured or the detection medium capture result is not up to standard, then the first detection information does not meet the requirements, and the detection element is kept monitoring the detection medium, and the detection information is continued to be obtained. For example, the target number is set to 3. If the detection medium is captured in the first cycle and the capture result meets the requirements, the detection medium cannot be captured in the second cycle or the third cycle, or the capture result is not up to standard, then it can be determined that the detection information does not meet the requirements, and when the detection medium is captured again and the capture result meets the requirements in the cycle, the detection medium is captured as the first cycle to continue monitoring. If the detection medium is captured in three consecutive cycles and the capture result meets the requirements, then the first detection information is determined to be valid.

[0072] Specifically, confirming the validity of the first detection information according to the first preset information including the preset time and the specified time period includes: S310, starting from the first cycle after the sensing component detects the target object on the transmission track, determining whether the capture result of the detection component on the detection medium in each cycle is valid; S320, if the capture result of the detection element on the detection medium is valid within a continuous preset number of cycles, then the first detection information is determined to be valid; S330: If not, determine that the first detection information is interference information.

[0073] The first detection information includes relevant capture information about the captured detection medium in each cycle, wherein the capture results of the detection medium captured by the detection element in multiple consecutive cycles after the detection component detects the presence of a target object on the transmission track from the sensing component include the duration of the detection medium captured by the detection element within the cycle range, and based on the duration being compared with the specified time period in the first preset information used to control the emission of the detection medium by the emission element, it is verified whether the capture result within the cycle range corresponds to the detection medium emitted by the emission element.

[0074] Therefore, it is judged whether the capture result of the detection element on the detection medium in each cycle is valid, including: Determine whether the difference between the duration of the detection medium captured in each cycle and the specified time period is within a valid range; If so, the capture result within the cycle is determined to be valid; If not, it is determined that the capture result within the cycle is invalid.

[0075] The difference is the allowable range of detection error of the detection component. The first threshold value within the effective range is TX1. If the difference △T is within the effective 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.

[0076] In step S500 of another embodiment, the second detection information includes a capture result of the detection medium captured by the detection element within a period after a switching moment, and the switching moment is a moment when the detection element emits the detection medium at a confirmation period different from a specified period within the period.

[0077] 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 by the emission element during the confirmation period. Therefore, the duration of the detection medium emitted by the emission element after the switching moment is also within the last cycle.

[0078] Specifically, confirming the validity of the second detection information according to the second preset information including the preset time and the confirmation period includes: In a period within a specified time after the switching moment, judging whether the capture result of the detection medium by the detection member in the period is valid, wherein the period within a specified time after the switching moment is the last period when the first detection information is valid; If so, it is determined that the second detection information is valid; If not, it is determined that the second detection information is interference information.

[0079] See also Figure 4 , the second detection information is also obtained by the detection element, and the duration of the detection medium is obtained in the preset time of the last cycle of the first detection information immediately after the transmitter switches the transmission mode, wherein the confirmation period t4 is located later than the designated period t2 in the last cycle T range, and the switching moment k3 is set between the designated period t2 and the confirmation period t4, so after the switching moment, the designated period t2 and the confirmation period t4 can be detected by the detection element in the same cycle, that is, the last cycle T, and the designated period t2 is captured in the first detection information, and the confirmation period t4 is captured in the second detection information. Therefore, according to the comparison of 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.

[0080] Therefore, judging whether the capture result of the detection element on the detection medium is valid includes: Determining whether the difference between the duration of the captured detection medium and the confirmation period is within a valid range; If so, the capture result is judged to be valid; If not, the capture result is judged to be invalid.

[0081] The difference is the detection error allowable range of the detection element, and the second threshold value within the effective range is TX2. If the difference △T is within the effective range, that is, △T≤TX2, 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. Among them, the second threshold value is set to be the same as the first threshold value in this embodiment, and of course it can also be set to a different value according to the actual situation, which is not limited here.

[0082] In addition, a method similar to the first detection information can be used to determine whether the capture results in each of the multiple consecutive cycles meet the requirements. The multiple consecutive cycles are two or more. In the capture results of the second detection information, not only the detection medium is captured in each of the multiple consecutive cycles, but also the capture information of the detection element in each cycle. The number of consecutive cycles can be reasonably designed according to actual conditions. The second detection information starts from the first cycle after the switching moment. If the target number of cycles is not reached, there is a cycle in the middle that does not capture the detection medium or the capture result of the detection medium does not meet the standard, then the second detection information does not meet the requirements and is judged as interference information.

[0083] 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 with 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. Here, 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 in the cycle with a confirmation period different from the specified period is immediately executed, so that the detection element immediately 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, which 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.

[0084] See also Fig.11In a third aspect, the present invention further proposes a transmission track control method, which is applied to a transmission device including 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: S1, controlling the transmission track to transmit the target object along the specified transmission path; S2, executing a detection calibration process of each sensing component on a specified transmission path of the target object, wherein the period of the detection medium emitted by the emitting element in each sensing component is synchronized, but the duration of the specified time period of the detection medium emitted by the emitting element of each sensing component within the period range is different; 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.

[0085] The method is applied in 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.

[0086] During the control process of the transmission track control method, the start signal for transmitting the target object can be initiated by the operation panel or the internal control program, and the 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, the detection and calibration process of each sensing component is performed to ensure the effectiveness of the detection of the sensing component and to confirm the effective transmission of the target object on the transmission track.

[0087] In the present embodiment, the detection medium emitted by each sensing component is periodically synchronized and easy to implement. The emitted detection medium is distinguished by the different durations of specified time periods within the cycle range. Therefore, during the detection calibration process 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 transmitting part of another sensing component, or some other interference signals.

[0088] The present embodiment may be configured as follows: 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.

[0089] 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. Fig. 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 components within the cycle; if the emission moment of the emission component is inconsistent with the capture moment of the detection component or is far apart, it can be judged in advance that the captured detection medium is not the detection medium emitted by the matching emission component.

[0090] It can be further extended to confirm that the time period and each specified time period are staggered and do not overlap within the cycle range. Fig. 9 The duration of the confirmation period is different from the duration 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 being captured by the detection component.

[0091] In addition, the transmission track control method further comprises: S4, after each sensing component has completed the detection calibration process of its corresponding detection position, when the sensing component detects that the target object leaves its corresponding detection position, it controls the emitting component of the sensing component to stop emitting the detection medium after waiting for a specific time.

[0092] Such a setting can reduce the waste of resources caused by the continuous operation of the sensing component. The specific waiting time is set to prevent the situation where the target object has not completely left the road section. If the target object is detected again within the specific time, the sensing component is controlled to continue the detection so that the target object leaves, or a detection error is performed. The sensing component detects that the target object has left its corresponding detection position, which can be confirmed based on whether the detection component of the sensing component receives the detection medium. If the detection component no longer receives the detection medium, it means that the target object has left, or if the detection information of the detection medium received by the detection component does not meet the validity verification of the first detection information, it means that the target object has left.

[0093] In some embodiments, the transmission track control method uses a pulse signal to control the emitting element of each sensing component to emit the detection medium at each corresponding designated time period within the cycle range, and the pulse width corresponding to the emission of the detection medium in each designated time period within the cycle range is different and the pulse bands corresponding to the emission of the detection medium are staggered. The pulse signal method is easy to control, and the emission and reception of the detection medium can be realized by only using high level and low level methods, which is simple and effective.

[0094] See also Figure 6 , the transmission track is used to transmit the bracket. When the detection position of at least two sensing components is the same as the detection position, and the bracket is located at the detection position, each sensing component performs the detection calibration process of the sensing component on the transmission track in the order of priority. The detection position refers to the position where the target object can be detected by at least two sensing components at the same time 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, it is necessary to perform the detection calibration process of each sensing component of the at least two sensing components according to the priority, so as to avoid affecting the detection calibration process of the sensing component of the high priority part due to the early execution of the detection calibration process of the low priority, resulting in the phenomenon of detection error.

[0095] The detection and calibration process of each sensing component on the transmission track according to the priority order includes: When there is only one bracket on the transmission track, the priority of the sensing component located at the front end of the transmission direction is higher than that of the sensing component located at the rear end of the transmission direction, and the detection and calibration process of the sensing components on the transmission track is performed in sequence; 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.

[0096] 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 executed 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 with priority on 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 may 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 executed first to effectively confirm whether the bracket is in the detection position.

[0097] 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 be performed preferentially. If the detection and calibration process is performed preferentially 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 to execute 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 preferentially to effectively confirm whether the bracket is in the detection position.

[0098] 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 a 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 a high priority are given priority to ensure the orderly operation of the transmission track.

[0099] The following is a description of the embodiments of single-bracket single-track operation, single-bracket cross-track operation, and multi-bracket cross-track operation.

[0100] Single carriage single track operation See also Figure 3 and Figure 5 There is a transmission section on the transmission track 10, and an induction component 20 is arranged in the transmission section. The emitting element 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 element to emit the detection medium is TS, and the specified time period for emitting the detection medium in the period TS is T1.

[0101] During the detection and calibration process of the sensing member 20, when the validity of the first detection information is confirmed, when the sensing member 20 detects the bracket 31 (ie Figure 3 ), it is determined whether the detection information fed back by the detection medium received by the detection element has a period TS and a pulse width T1. If it is detected that the pulse width of the detection information fed back by the detection medium is within the valid range within M consecutive periods, that is, T1-TX1≤L1≤T1+TX1, L1 is the actual detection value, then it is determined that the first detection information detected by the detection element is valid, otherwise the first detection information is an interference signal.

[0102] 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 element emitting 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 it is judged that the second detection information of the sensing component 20 for the bracket 31 is valid information.

[0103] When the second detection information is determined to be valid information according to the sensing member 20, the transmission track 10 is controlled to stop transmitting the bracket 31, and the bracket 31 is transmitted to the position. In this embodiment, the transmission track 10 can be driven by a motor, and the transmission track 10 is controlled to stop or transmit by controlling the motor.

[0104] Single carriage running across tracks See also Figure 6 and Figure 7 , there are two transmission sections on the transmission track, a first sensing component 24 is arranged in the first transmission section 11, and a second sensing component 25 and a third sensing component 26 are arranged in the second transmission section 12. When a single bracket 31 is transmitted on the transmission track, due to the length factor of the bracket 31 itself, there is a possibility that the first sensing component 24 and the second sensing component 25 work at the same time, that is, the signals emitted by the first sensing component 24 and the second sensing component 25 can detect the bracket 31 at the same time, while the other sensing components do not detect the bracket 31 at this time. In this case, the priority of the second sensing component 25 that is about to arrive is higher than the second sensing component 24 that is about to leave. At the same time, since the third sensing component 26 is not in the working state of sensing the bracket 31, its priority is set to the lowest, so the detection and calibration process of the second sensing component 25 is performed first.

[0105] 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.

[0106] 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 it is determined that the first detection information detected by the detection component is valid. Otherwise, the first detection information is an interference signal.

[0107] 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 element emitting 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.

[0108] 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.

[0109] After executing 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 leaves its detection position, after maintaining a specific time T0, the emitting element of the first sensing component 24 is controlled to stop emitting the detection medium.

[0110] 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 detected as valid information during the detection and calibration process, the transmission track is controlled to stop running and it is determined that the bracket 31 is transferred to the right position.

[0111] Multiple carriages running across tracks See also Figure 8 and Fig. 9 , there are three transmission sections on the transmission track, the first transmission section 11 has a first sensing component 24, the second transmission section 12 has a second sensing component 25 and a third sensing component 26, and the third transmission section 13 has a fourth sensing component 27 and a fifth sensing component 28. When the bracket 31 exists 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 work at the same time. At this time, the priority of executing 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 the bracket 31 is detected. Fig. 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.

[0112] 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, wherein 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.

[0113] The first sensing member 24 can be set as a first in-position sensing member, the second sensing member 25 can be set as a deceleration sensing member, the third sensing member 26 can be set as a second in-position sensing member, the fourth sensing member 27 can be set as a deceleration sensing member, and the fifth sensing member 28 can be set as a third in-position sensing member. In addition, multiple sensing members can be set separately, and when the sensing members detect that the bracket 31 has arrived at the corresponding transmission position, corresponding actions are performed, so that the orderliness of the overall control of the conveying device can be achieved.
