Specific embodiments

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0028] To solve the problems mentioned in the background art, according to one aspect of the embodiments of the present application, embodiments of a method for detecting faults in a meal delivery cabinet are provided.

[0029] It should be noted that the method for detecting faults in a meal delivery cabinet provided by the embodiments of the present application is generally executed by a server and / or a terminal device. Correspondingly, the device for detecting faults in a meal delivery cabinet is generally disposed in the server / terminal device.

[0030] Taking the case where the method for detecting faults in a meal delivery cabinet is executed by a server as an example, for the method for detecting faults in a meal delivery cabinet, the meal delivery cabinet includes a plurality of moving parts, such as Figure 1 As shown, the method includes the following steps:

[0031] Step S102, determining whether the communication of each moving part is normal according to the data feedback status of each moving part, where the moving parts include a mobile device, a food delivery channel, a lifting device, and a food outlet baffle.

[0032] In this embodiment, when in the process of user use, if it is detected that the user places an order, the communication status of each moving part can be detected after or before placing the order. Among them, communication modules can be respectively provided on each moving part, and communication with the control system of the meal delivery cabinet can be realized based on the communication module to receive various instructions issued by the control system or feedback data to the control system, etc.

[0033] Further, during communication status detection, the control system can send communication signals to each moving component. If a feedback signal indicating that the communication signal has been received is returned from the moving component, it means that the moving component is in a normal communication state, and subsequent meal pickup and delivery operations can be performed. If a feedback signal indicating that the communication signal has been received is not returned from the moving component, it means that the moving component is in an abnormal communication state. If the communication is abnormal, a communication abnormality prompt can be generated in the control system to facilitate timely maintenance by the staff. For example: The control system sends a signal to establish communication to the communication modules of the mobile device, the meal delivery channel, the lifting device, and the meal outlet baffle. Within 3 seconds, the mobile device and the meal delivery channel return "confirmation", while the lifting device and the meal outlet baffle do not give feedback, indicating that there is a communication fault in the lifting device and the meal outlet baffle, and it needs to be detected in time.

[0034] It should be noted that only when the above-mentioned mobile device, meal delivery channel, lifting device, and meal outlet baffle are all in a normal communication state can the control system completely realize the control of the mobile device, meal delivery channel, lifting device, and meal outlet baffle, and then completely realize the meal pickup and delivery functions. If any moving component cannot communicate, the delivery will be affected.

[0035] Step S104, when the communication of each moving component is normal, during the delivery process, the state data of the mobile device and the meal outlet baffle are respectively obtained, and different types of state data are collected based on different detection sensors provided on the moving components.

[0036] Among them, when the mobile device, meal delivery channel, lifting device, and meal outlet baffle are all in normal communication, the delivery process can be started. In this embodiment, detection sensors can be provided on each of the moving components of the mobile device, meal delivery channel, lifting device, and meal outlet baffle, or detection sensors can be provided on some of the moving components. Considering that setting more detection sensors is not only complex but also increases costs, in this embodiment, detection sensors can be provided on the moving device and the meal outlet baffle. Among them, when the detected state data is different, the types of the corresponding detection sensors are also different. For example, to detect the moving distance of the mobile device, it is realized based on an ultrasonic sensor; when detecting the weight of the meal on the meal pickup platform placed on the mobile device, it is realized based on a pressure sensor.

[0037] In some examples, when in different positions, the state data corresponding to different positions can be collected by the same detection sensor provided on the mobile device. For example, an ultrasonic sensor is provided on the mobile device, and based on the ultrasonic sensor, the corresponding distance when the mobile device moves to the meal delivery channel to pick up the meal is collected, or the corresponding distance when the mobile device moves to the meal outlet after picking up the meal is collected based on the ultrasonic sensor.

[0038] Further, after the mobile device moves to a different position, status detection is performed based on the corresponding detection sensors. After each detection sensor collects the corresponding status data, the status data can be sent to the control system background for fault judgment.

[0039] Step S106, perform fault judgment on the mobile device, the food delivery channel, the lifting device, and the food outlet baffle according to the status data of the mobile device and the food outlet baffle to determine the target fault location.

[0040] Among them, based on the analysis of the obtained status data of the mobile device and the food outlet baffle, it is possible to determine which one of the mobile device, the food delivery channel, the lifting device, and the food outlet baffle is the location where the fault occurs, and then determine the target fault location. For example, when it is necessary to move the mobile device from the first-floor food delivery channel to the pick-up port 1 on the third-floor food delivery channel by controlling the lifting device to pick up food, the ultrasonic sensor adjusts the detection direction to face the food delivery channel directly, and then performs distance detection within 5 seconds continuously. If the detected distance changes, it means that the lifting device has no fault. If the distance does not change during the continuous detection process, it means that the lifting device has a fault and cannot realize the lifting function.

[0041] Further, after determining the target fault location, the background control system can generate a fault prompt message for display through the touch screen to prompt, or send it to the corresponding maintenance personnel to realize the status of the meal delivery cabinet through the remote terminal, so as to take corresponding maintenance measures in time, minimize the downtime, and ensure the continuous and stable operation of the system. Among them, the fault prompt message can include information such as the faulty component and the fault time.

[0042] In the embodiment of the present invention, by obtaining the data feedback status of multiple key moving components such as the mobile device, the food delivery channel, the lifting device, and the food outlet baffle, it is possible to quickly and accurately judge whether the communication of each moving component is normal; on the premise of normal communication, different detection sensors arranged on the moving components are used to collect the status data of the mobile device and the food outlet baffle in real time, and comprehensive fault judgment is performed on all moving components based on the collected status data, significantly shortening the fault location time, enabling the operation and maintenance personnel to quickly respond to and handle faults, effectively improving the overall operation efficiency and operation stability of the meal delivery cabinet; and through multi-dimensional data collection and analysis for fault judgment, it is possible to more accurately identify the specific location where the fault occurs.

[0043] In some optional embodiments, the above step S104 specifically includes:

[0044] S1041, when the communication of each moving part is normal, if the mobile device receives a meal pickup instruction, then control the lifting device to move the mobile device to the target meal pickup position in the target meal delivery channel;

[0045] S1042, when moving to the target meal pickup position, obtain the status data collected based on the position detection sensor provided on the mobile device, where the status data includes the meal pickup position data generated when the mobile device moves from the initial position to the target meal pickup position.

[0046] Among them, when the communication of each moving part is normal, the control system can send instructions to each moving part to control the operation of each moving part. The operation process of each moving part is as follows: First, control the lifting device to move the mobile device to the target meal delivery channel, then the mobile device moves based on its own track to reach the target meal pickup position. After successfully picking up the meal, continue to control the lifting device to move the mobile device to the height where the meal outlet is located, and the mobile device moves on its track to the position of the meal outlet baffle. After the meal outlet baffle is opened, the meal is pushed out through the push plate on the mobile device for the user to pick up the meal.

[0047] In this embodiment, when the user selects a meal, each meal has a corresponding meal delivery channel and meal pickup position. If the mobile device receives a meal pickup instruction, then control the mobile device to start moving up and down through the lifting device to reach the target meal delivery channel, and then control the device to move on the track to reach the corresponding target meal pickup position to pick up the meal. The ultrasonic sensor provided on the mobile device can collect the meal pickup position data. Based on the meal pickup position data, it can be judged whether the height of the mobile device has changed, that is, when the mobile device successfully moves from the current initial position to the target meal pickup position, the meal pickup position data should change. If it does not change, it means that the lifting device has not started to move up and down. For example, taking the lowest layer (the first layer) as the reference height of 0, when moving from the meal delivery channel on the first layer to the meal delivery channel on the third layer, the moving height is 60 cm, and if the height continuously detected by the ultrasonic sensor is still 0, it means that the lifting device has not performed the lifting action.

[0048] In this embodiment, after the mobile device receives a meal pickup instruction, control the lifting device to move the mobile device to the target meal delivery channel, and the mobile device then moves horizontally to the target meal pickup position to pick up the meal. When moving to the target meal pickup position, obtain the meal pickup position data collected based on the ultrasonic detection sensor provided on the mobile device, so that it can be determined whether the lifting device moves up and down according to the meal pickup position data, which is beneficial to quickly judge whether there is a failure in the lifting device.

[0049] In some alternative embodiments, the above step S104 specifically further includes:

[0050] S1043, when the communication of each moving part is normal, if the mobile device reaches the target meal pickup position, control the rollers on the mobile device and the tracks on the meal delivery channel to rotate;

[0051] S1044, obtain the rotation data of the rollers collected by the rotation speed sensors arranged on the rollers of the mobile device, and after obtaining the rotation data of the rollers, obtain the weight data collected by the first pressure sensors arranged on the bottom plate of the mobile device.

[0052] In this embodiment, when the mobile device reaches the target meal pickup position, the control system will send an instruction to control the rollers of the mobile device and the tracks on the meal delivery channel to rotate. At this time, the rotation data of the rollers can be collected by the rotation speed sensors arranged on the rollers of the mobile device. If the rotation data changes, it can indicate that the rollers are rotating. For example, when the rollers are not rotating, the rotation speed is 0 rad / s, and the detected rotation data is 10 rad / s, which means the rollers are rotating. Among them, the rotation speed of the rollers can be preset. To ensure the stable transmission of meals, the rotation speed should not be too fast.

[0053] Furthermore, to determine whether the mobile device has received the meals conveyed from the meal delivery channel, a first pressure sensor can also be set on the bottom plate of the mobile device. The upper end surface of the bottom plate is the platform for placing meals. The weight data can be collected through the pressure sensor, and through the weight data, it can be determined whether the tracks of the meal delivery channel are rotating to convey the meals to the mobile device. For example, when no meals are placed on the mobile device, the weight data collected by the first pressure sensor is 0 g, and when meals are placed on the mobile device, the weight data is greater than 0 g.

[0054] In this embodiment, after the mobile device reaches the target meal pickup position, by controlling the rotation of the rollers and tracks, obtaining the rotation data of the rollers through the rotation speed device on the rotating device, and obtaining the weight data based on the first pressure sensor on the bottom plate of the rotating device, it is possible to determine whether the rollers are rotating normally based on the rotation data, and determine whether the tracks are rotating normally based on the weight data, which is more conducive to quickly and accurately locking whether there is a fault in the rollers or the meal delivery channel.

[0055] In some optional embodiments, the above step S104 specifically further includes:

[0056] S1045, after obtaining the weight data of the bottom plate of the mobile device, if the mobile device receives a meal delivery instruction, control the lifting device to move the mobile device to the target meal delivery port;

[0057] S1046. When moving to the target food delivery opening, obtain the food delivery position data collected from the target food pickup position to the target food delivery opening based on the position detection sensor provided on the mobile device.

[0058] In this embodiment, after the weight data is obtained, it can be determined whether the food delivery channel is faulty based on the weight data. If there is no fault, the mobile device will be controlled to deliver food. For this, the control system will send a food delivery instruction to the mobile device, and under the up and down movement control of the lifting device, the mobile device will be sent to the height where the target food delivery opening is located. The mobile food cart on the mobile device moves horizontally based on the track on the mobile device, so as to deliver the food to the position of the food delivery opening baffle.

[0059] In some examples, at least one food delivery opening can be provided on the meal delivery cabinet. When there are multiple food delivery openings, the food delivery openings without food placed can all be used as the target food delivery openings. Preferably, if there are multiple food delivery openings without placed food, the food delivery opening with the smallest height difference from the height where the target food pickup position is located is used as the target food delivery opening. In this way, it is more conducive to accelerating the food delivery speed and improving the food delivery efficiency.

[0060] Furthermore, the food delivery position data collected from the target food pickup position to the target food delivery opening can be obtained through the ultrasonic sensor on the mobile device. Among them, the height where the food delivery opening baffle is located is different from the height of any layer of the food delivery channel. For this, when the mobile device moves from the target food pickup position to the target food delivery opening, the collected food delivery position data will change. Based on the collected food delivery position data, it can be determined whether the mobile device has changed in height, and thus it can be determined whether the lifting device moves up and down according to the food delivery position data.

[0061] In this embodiment, after the mobile device receives the food delivery instruction, the lifting device is controlled to move the mobile device to the height where the target food delivery opening is located, so as to use the position detection sensor provided on the mobile device to collect the food delivery position data from the target food pickup position to the target food delivery opening. Based on the food delivery position data, it can be determined whether the mobile device has changed in height, which is more conducive to quickly and accurately determining whether the lifting device is faulty according to the food delivery position data.

[0062] In some optional embodiments, the above step S104 specifically further includes:

[0063] S1047. In the food delivery stage, if the mobile device and the food delivery opening baffle receive a movement instruction, control the push plate of the mobile device and the food delivery opening baffle to move so that the delivered food is sent to the target food delivery opening;

[0064] S1048, obtain the pusher plate movement data collected based on the position detection sensor set on the mobile device, and obtain the baffle plate pressure data collected based on the second pressure sensor set at the food outlet baffle.

[0065] In this embodiment, a pusher plate can be set on the mobile device. Based on the pusher plate, the meal can be pushed out of the mobile device to be delivered to the target food outlet for the user to pick up. When the mobile device delivers the meal to the position of the food outlet baffle, the control system can send a movement instruction to control the movement of the pusher plate on the mobile device, and send a movement instruction to control the opening of the baffle to the food outlet baffle. Under normal operation, after receiving the movement instructions respectively, the pusher plate and the food outlet baffle start to work. The food outlet baffle opens, and the pusher plate pushes the meal placed on the mobile device to the outside of the target food outlet for the user to pick up.

[0066] Furthermore, the pusher plate movement data can be collected by the ultrasonic sensor on the mobile device. Based on the pusher plate movement data, it can be determined whether the pusher plate moves normally. For example, if the pusher plate movement data collected by the ultrasonic sensor is 0m, it means the pusher plate does not move. At this time, the position of the ultrasonic sensor is directly opposite the pusher plate to collect data more accurately. Since the food outlet baffle will contact the side wall of the box body at the food outlet when it is closed, a second pressure sensor is set at the position where the pressure generated by contacting the box body can be felt at the food outlet baffle. Through the second pressure sensor, the baffle plate pressure data can be collected. Based on whether the baffle plate pressure data changes, it can be judged whether the food outlet baffle expands and contracts normally. For example, if the baffle plate pressure data collected by the second pressure sensor is 0Pa, it means the food outlet baffle is in the open state.

[0067] In this embodiment, by controlling the movement of the pusher plate and the food outlet baffle of the mobile device to deliver the distributed meal to the target food outlet, obtaining the pusher plate movement data collected based on the ultrasonic sensor, and obtaining the baffle plate pressure data collected based on the second pressure sensor, it can be judged whether the pusher plate moves based on the pusher plate movement data, and it can be judged whether the food outlet baffle expands and contracts normally through the baffle plate pressure data, which is more conducive to quickly and accurately judging whether it is a failure of the food outlet baffle or the pusher plate of the mobile device.

[0068] In some optional embodiments, the above step S106 specifically includes:

[0069] S1061, if the pick-up position data or the food outlet position data of the mobile device does not change, it is determined that the lifting device fails;

[0070] S1062, if the rotation data of the roller does not change, it is determined that the roller fails;

[0071] S1063, if the weight data of the mobile device remains unchanged, it is determined that a failure has occurred in the meal delivery lane;

[0072] S1064, if the push plate movement data of the push plate in the mobile device remains unchanged, it is determined that a failure has occurred in the push plate;

[0073] S1065, if the baffle pressure data of the meal outlet baffle remains unchanged, it is determined that a failure has occurred in the meal outlet baffle.

[0074] In this embodiment, when the obtained pick-up position data of the mobile device does not change, it indicates that the lifting device has not moved up and down to control the mobile device to move to the target meal delivery lane. In this case, it is determined that a failure has occurred in the lifting device. If the pick-up position data does not change, it indicates that the lifting device has not moved the mobile device to the height where the meal outlet baffle is located for meal delivery. In this case, it is determined that a failure has occurred in the lifting device. If the rotation data of the roller does not change, it indicates that the roller does not rotate. At this time, it is determined that a failure has occurred in the roller. If the weight data of the mobile device does not change, it indicates that the track of the meal delivery lane does not rotate, and thus the meal is not conveyed to the mobile device. In this case, it is determined that a failure has occurred in the meal delivery lane, which may be the track or the device controlling the rotation of the track. When the push plate movement data of the push plate of the mobile device does not change, it indicates that when delivering the meal, the push plate on the mobile device does not push the meal to place it at the meal outlet. In this case, it is determined that a failure has occurred in the push plate. When the baffle pressure data of the baffle of the mobile device does not change, it indicates that the baffle does not move and remains in its original state, which may be open or closed. In this case, it is determined that a failure has occurred in the meal outlet baffle.

[0075] In some examples, when any moving part fails, corresponding fault prompt information can be generated for maintenance personnel to perform targeted maintenance, thereby shortening the fault maintenance time and ensuring the stable operation of the meal delivery cabinet. To ensure the stable operation of the meal delivery cabinet, during the process of delivering meals for the user's order, fault detection can be performed regularly and repeatedly.

[0076] In some examples, the above fault judgment order can be sequentially judged based on the meal delivery order, that is, first pick up the meal and then deliver the meal. Correspondingly, the acquisition of status data and the fault judgment order are also based on the order from picking up the meal to delivering the meal. If the previously judged moving part has no fault, continue to judge the fault of the subsequent moving part; if the previously judged moving part has a fault, at this time, the meal delivery cabinet cannot continue to operate normally, and in this case, the fault judgment of the subsequent moving part will not be continued. If it is sequentially judged that all moving parts have no fault, then pick up the meal and deliver the meal normally.

[0077] In this embodiment, by locking the target fault location according to the changes in the meal pickup position data, meal delivery position data, weight data, drum rotation data, pusher plate movement data of the pusher plate, and baffle pressure data of the meal outlet baffle of the mobile device collected, not only is manual intervention reduced, but also the operating state of the meal delivery cabinet can be comprehensively monitored. Through the collaborative work of each sensor, the target fault location can be accurately and quickly located, the fault location time can be shortened, and the fault location accuracy can be improved.

[0078] In some alternative embodiments, step S102 specifically includes:

[0079] S1021, sending communication signals to the mobile device, meal delivery channel, lifting device, and meal outlet baffle through the control system of the meal delivery cabinet, wherein communication modules for communicating with the control system are provided on the mobile device, meal delivery channel, lifting device, and meal outlet baffle;

[0080] S1022, if communication feedback signals returned by the mobile device, meal delivery channel, lifting device, and meal outlet baffle are respectively obtained within a preset time period, it is determined that the communication of the mobile device, meal delivery channel, lifting device, and meal outlet baffle is normal.

[0081] Among them, communication modules can be respectively provided on each moving part. Based on the communication module, communication with the control system of the meal delivery cabinet can be realized to receive various instructions issued by the control system or feedback data to the control system, etc. During communication status detection, the control system can send communication signals to each moving part based on a preset communication exchange protocol. If a feedback signal of the received communication signal returned by the moving part is received within a preset time period, it indicates that the moving part is in a normal communication state, and subsequent meal pickup and delivery operations can be carried out. If a feedback signal of the received communication signal returned by the moving part is not received within a preset time period, it indicates that the moving part is in an abnormal communication state. If the communication is abnormal, a communication abnormality prompt can be generated in the control system to facilitate timely maintenance by the staff. For example: The control system sends a signal to establish communication to the communication modules of the mobile device, meal delivery channel, lifting device, and meal outlet baffle. Within 5 seconds, the mobile device and the meal delivery channel return "confirmation", while the lifting device and the meal outlet baffle do not give feedback signals, indicating that there are communication faults in the lifting device and the meal outlet baffle and need to be detected in time.

[0082] In some examples, if no feedback signal of the moving component is received within a preset time period, communication signals can be sent to the non-feedback moving component at regular intervals based on a preset number of times, and communication connections can be established multiple times. If the communication connection still cannot be successfully established, it indicates that the moving component is not under the control of the control system, and the communication module on it may be faulty. In this regard, as long as there is a situation of moving component failure, it means that the meal delivery cabinet cannot deliver meals normally, and it will not be started immediately. It will be started again after the fault is reported and repaired.

[0083] In this embodiment, the control system uniformly sends communication signals to the mobile device, the meal delivery channel, the lifting device, and the meal outlet baffle, and determines whether communication feedback signals returned by each moving component are respectively obtained within a preset time period, so as to be able to detect the communication status of the mobile device, the meal delivery channel, the lifting device, and the meal outlet baffle in real time. Once a certain component fails to return a communication feedback signal within the specified time, the system can immediately determine that the communication of this component is abnormal, so as to timely discover potential fault hazards and provide a basis for subsequent fault troubleshooting and repair.

[0084] As a possible implementation manner, in combination with Figure 2 shown in Figure 2 is another flow chart for judging the failure of the moving component provided in this embodiment. When the meal delivery cabinet is started and running, if there is a user using it, the control system will send communication signals to each moving component based on the communication exchange protocol. After each moving component receives the communication signal instruction and returns feedback information, the control system will issue a meal pickup instruction to control the lifting device to move the mobile device to a certain meal delivery channel, and then use the ultrasonic sensor set on the mobile device to judge whether the lifting device controls the mobile device to move to the corresponding meal delivery channel. If not, it is determined that the lifting device is faulty; if so, the control system issues an instruction to control the roller of the mobile device to pick up the meal and control the caterpillar of the meal delivery channel to deliver the meal. The rotation sensor on the roller is used to judge whether the roller rotates. If the roller rotates, the first pressure sensor is used to detect whether the weight on the mobile device increases. If not, it is determined that the meal delivery channel is faulty; if so, it means that the mobile device is filled with meals. In this regard, the control system further issues a meal delivery instruction to control the lifting device to move the mobile device to any meal outlet, and the ultrasonic sensor on the mobile device is used again to judge whether the lifting device controls the mobile device to move to the corresponding meal outlet. If not, it is determined that the lifting device is faulty; if so, the control system issues a movement instruction to control the push plate and the meal outlet baffle on the mobile device to move, and the ultrasonic sensor on the mobile device is used again to detect whether the push plate moves. If not, it is determined that the push plate is faulty; if so, it means that each moving component is working normally. Whenever a fault is sent, an error message will be generated.

[0085] As another possible implementation manner, in combination with Figure 3 shown inFigure 3 Another flowchart for fault judgment of moving parts provided in this embodiment. During the fault detection process, during different movement processes, data collection of the moving distance is performed based on the ultrasonic sensors arranged on the mobile device to determine whether the lifting device is faulty and whether the push plate of the mobile device is faulty. Weight detection is performed based on the first pressure sensor arranged on the mobile device to determine whether the food delivery channel is faulty. Pressure detection is performed based on the second pressure sensor arranged at the baffle of the food outlet to determine whether the baffle of the food outlet is faulty. It is determined whether the roller is rolling based on the rotation sensor arranged on the roller. When all moving parts are free of faults, it is determined that each moving part is normal.

[0086] In some possible embodiments, when no user uses the meal delivery cabinet for ordering services, the moving parts can also be monitored and maintained. During the monitoring and maintenance process, the entire delivery process of taking and delivering meals is simulated regularly, for example, once every 3 hours. During the simulation process, the status data of each moving part is collected through each sensor for data analysis. Once a fault is found, the control system will trigger a fault alarm, send a maintenance request to the maintenance personnel, and record the fault information at the same time. Among them, the monitoring and maintenance is the self-start of the unit. During the monitoring and maintenance process, if a user is using it, the detection will be postponed for a set time and then carried out, for example, postponed for 10 minutes. Conducting monitoring and maintenance when there is no user can detect faults in a timely manner when not in use. This real-time monitoring and rapid response mechanism can minimize the equipment downtime and ensure the continuous and stable operation of the system.

[0087] As a possible embodiment, in combination with Figure 4As shown in the figure, the process of detection and maintenance includes: the control system issues an instruction for the mobile device to pick up meals, controls the mobile device to move to a certain meal delivery channel, and uses an ultrasonic sensor to determine whether the lifting device controls the mobile device to move to the corresponding meal delivery channel. If not, the control system controls the switching to the manual meal picking mode and reports an error; if so, the control system issues a rotation instruction for controlling the drum and the push plate of the mobile device to move, and uses a rotational speed sensor to determine whether the drum rotates. If not, the control system controls the switching to the manual meal picking mode and reports an error; if it rotates, uses an ultrasonic sensor to determine whether the push plate moves. If not, the control system controls the switching to the manual meal picking mode and reports an error; if it moves, then issues a meal delivery instruction for the mobile device, and controls the mobile device to randomly move to a certain meal outlet. Continue to use the ultrasonic sensor to determine whether the lifting device controls the mobile device to move to the corresponding meal outlet. If not, the control system controls the switching to the manual meal picking mode and reports an error; if so, then issues a moving instruction for the meal outlet baffle, and uses a pressure sensor to determine whether the baffle moves normally. If not, the control system controls the switching to the manual meal picking mode and reports an error; if it moves, then controls the mobile device and the meal outlet baffle to reset. Subsequently, automatically detect whether each moving part is abnormal every 3 hours. If there is an abnormality, the control system switches to the manual meal picking mode, sorts out the error information, and sends a maintenance request to the preset maintenance team.
