[0031] Combination Figure 1 As shown, an embodiment of the present disclosure provides a vending machine. The vending machine includes: a door body 1, a first infrared device 2, a second infrared device 3, a cargo storage bin 4, and a pickup port 5. The door body 1 is adjacent to the pickup port 5 of the vending machine. The first infrared device 2 is used to transmit and receive a first infrared ray in the cargo storage bin 4 of the vending machine. The second infrared device 3 is used to transmit and receive a second infrared ray at the pickup port 5 of the vending machine. The door body 1 can be opened or closed by the first infrared ray and the second infrared ray.

[0032] Optionally, the first infrared device 2 includes a first infrared transmitting module 21 for transmitting first infrared rays and a first infrared receiving module 22 for receiving first infrared rays. The second infrared device 3 includes a second infrared transmitting module 31 for transmitting second infrared rays and a second infrared receiving module 32 for receiving second infrared rays.

[0033] Optionally, when the goods have not entered the cargo storage bin 4, both the first infrared ray and the second infrared ray are unblocked, and the control door body 1 is closed. When the goods have entered the cargo storage bin 4 and the user has not reached into the cargo storage bin 4 and the pickup port 5, the first infrared ray is blocked and the second infrared ray is unblocked, and the control door body 1 is opened. When the goods have entered the cargo storage bin 4 and the user has reached into the cargo storage bin 4 from the pickup port 5, both the first infrared ray and the second infrared ray are blocked, and the control door body 1 remains open. When the user takes the goods from the cargo storage bin 4 to the pickup port 5, the first infrared ray is unblocked and the second infrared ray is blocked, and the control door body 1 remains open. When the user takes the goods out of the pickup port 5, both the first infrared ray and the second infrared ray are unblocked, and the control door body 1 is closed.

[0034] In the vending machine provided by the embodiment of the present disclosure, the first infrared device 2 in the cargo storage bin 4 can emit and receive the first infrared ray, and can detect whether there is cargo entering the cargo storage bin 4 from the delivery port and the removal of cargo according to the blocking of the first infrared ray. The second infrared device 3 arranged at the pickup port 5 can emit and receive the second infrared ray, and can detect whether the user has taken the action of picking up cargo and the removal of cargo according to the blocking of the second infrared ray. The door body 1 can be opened or closed by the first infrared ray and the second infrared ray, and there is no need to manually open and close the door to pick up cargo, which is conducive to reducing the difficulty of picking up cargo, improving user experience, and conforming to the concept of contactless service.

[0035] Combination Figure 2 As shown, the embodiment of the present disclosure provides a method for fault detection, including:

[0036] S201, the vending machine determines a transition condition of a shielding state of the first infrared ray and / or the second infrared ray.

[0037] S202: The automatic vending machine determines a fault type of the automatic vending machine according to a change in the shielding state of the first infrared ray and / or the second infrared ray.

[0038] By adopting the method for fault detection provided by the embodiment of the present disclosure, the first infrared device in the cargo storage bin can emit and receive the first infrared ray, and can detect whether there is any cargo entering the cargo storage bin from the delivery port and the removal of the cargo according to the blocking condition of the first infrared ray. The second infrared device arranged at the pickup port can emit and receive the second infrared ray, and can detect whether the user has taken the action of picking up the cargo and the removal of the cargo according to the blocking condition of the second infrared ray. The door body can be opened or closed by the first infrared ray and the second infrared ray, and there is no need to manually open and close the door to pick up the cargo, which is conducive to reducing the difficulty of picking up the cargo, improving the user experience, and complying with the concept of contactless service. And according to the change of the blocking state of the first infrared ray and / or the second infrared ray, the fault type of the vending machine is determined, which is conducive to making up for the disadvantage that the low-cost infrared device does not have fault self-detection and improving the safety of the vending machine.

[0039] Optionally, the change of the shielding state of the first infrared ray and / or the second infrared ray includes: the change of the shielding state of the first infrared ray in the delivery link, or the change of the shielding state of the first infrared ray and the second infrared ray in the pickup link.

[0040] In this way, the fault type of the vending machine can be determined based on the change in the blocked state of the first infrared ray in the delivery link, or the change in the blocked state of the first infrared ray and the second infrared ray in the pickup link. This is helpful to make up for the disadvantage that low-cost infrared equipment does not have fault self-detection and improve the safety of the vending machine.

[0041] Optionally, the change of the shielding state of the first infrared ray in the shipping link includes: the shielding state of the first infrared ray in the shipping link changes, or the shielding state of the first infrared ray in the shipping link does not change.

[0042] This is helpful to better determine the change of the shielding state of the first infrared ray in the shipping link.

[0043] Optionally, the shielding state of the first infrared ray in the shipping link changes, including: the shielding state of the first infrared ray in the shipping link changes from unshielded to blocked.

[0044] In this way, the blocked state of the first infrared ray in the shipment link changes from unblocked to blocked, which means that in the shipment link, the goods enter the goods storage warehouse, blocking the first infrared ray, and the shipment is normal.

[0045] Optionally, the blocked state of the first infrared ray in the shipping link does not change, including: the blocked state of the first infrared ray in the shipping link remains unblocked.

[0046] In this way, the first infrared ray remains unblocked in the shipping link, which means that the goods have not entered the goods storage bin in the shipping link, such as a failure of the shipping port, or a failure of the first infrared device has caused abnormal shipping.

[0047] Optionally, the transformation of the blocked state of the first infrared ray and the second infrared ray in the picking-up link includes: the blocked state of the first infrared ray and the second infrared ray in the picking-up link both transforms. Or, the blocked state of the first infrared ray in the picking-up link does not transform, and the blocked state of the second infrared ray in the picking-up link transforms. Or, the blocked state of the first infrared ray in the picking-up link transforms, and the blocked state of the second infrared ray in the picking-up link does not transform. Or, the blocked state of the first infrared ray and the second infrared ray in the picking-up link do not transform.

[0048] This is helpful to better determine the transition of the shielding status of the first infrared ray and the second infrared ray in the picking process.

[0049] Optionally, the blocked state of the first infrared ray in the goods picking link changes, including: the blocked state of the first infrared ray in the goods picking link changes from being blocked to being unblocked.

[0050] In this way, if the shipping process is normal, the initial shielding state of the first infrared ray in the picking-up process is shielding, and if the goods are taken out, the shielding state of the first infrared ray is changed to unshielding.

[0051] Optionally, the blocked state of the first infrared ray in the goods picking link does not change, including: the blocked state of the first infrared ray in the goods picking link remains blocked.

[0052] In this way, if the shipping process is normal, the first infrared ray will be initially blocked in the pickup process; if the pickup is not completed, foreign objects are retained, or the first infrared device fails, the first infrared ray will remain blocked.

[0053] Optionally, the blocked state of the second infrared ray in the picking-up link changes, including: the blocked state of the second infrared ray in the picking-up link changes from unblocked to blocked, and / or, changes from blocked to unblocked.

[0054] In this way, if the second infrared ray changes from being unblocked to being blocked, and / or from being blocked to being unblocked during the picking-up process, it indicates that the user's hand has reached into the picking-up port to pick up the goods. Thereafter, if the second infrared ray changes from being blocked to being unblocked during the picking-up process, it indicates that the user has taken out the goods.

[0055] Optionally, the blocked state of the second infrared ray in the goods picking link does not change, including: the blocked state of the second infrared ray in the goods picking link remains unblocked or remains blocked.

[0056] In this way, if the second infrared ray remains unblocked during the pickup link, it indicates that the user did not reach in to pick up the goods or the second infrared device is faulty. If the second infrared ray remains blocked during the pickup link, it indicates that the user reached in to pick up the goods but did not take them out or the second infrared device is faulty.

[0057] Optionally, the vending machine determines the fault type of the vending machine according to the change of the blocked state of the first infrared ray and / or the second infrared ray, including: in the case of the delivery link, the vending machine determines the fault type of the vending machine as delivery failure or first infrared device failure according to the change of the blocked state of the first infrared ray in the delivery link. Or, in the case of the pickup link, the vending machine determines the fault type of the vending machine as delivery port failure, second infrared device failure or pickup port abnormality according to the change of the blocked state of the first infrared ray and the second infrared ray in the pickup link.

[0058] In this way, the goods in the shipping process only need to be blocked or unblocked by the first infrared ray, and the fault is determined to be a shipping failure or a first infrared device failure according to the blocking of the first infrared ray. The goods collection process involves the blocking or unblocking of both the first infrared ray and the second infrared ray, and the fault is determined to be a shipping port failure, a second infrared device failure, or a pick-up port abnormality according to the blocking status of the first infrared ray and the second infrared ray. This is conducive to more accurate positioning of the fault of the vending machine.

[0059] Optionally, the vending machine determines that the fault type of the vending machine is a shipment failure or a first infrared device failure according to the change of the blocked state of the first infrared ray in the shipment link, including: when the blocked state of the first infrared ray in the shipment link does not change, the vending machine determines that the fault type of the vending machine is a shipment failure or a first infrared device failure. Specifically, when the vending machine determines that the fault type of the vending machine is a shipment failure or a first infrared device failure, the shipment failure is reported and after-sales maintenance is applied.

[0060] In this way, in the delivery link, if the shielded state of the first infrared ray does not change, the vending machine fails, and the failure type is delivery failure or first infrared device failure.

[0061] Optionally, the vending machine determines the fault type of the vending machine as a delivery port fault, a second infrared device fault or a pickup port abnormality according to the change of the blocked state of the first infrared ray and the second infrared ray in the pickup link, including: when the blocked state of the first infrared ray in the pickup link does not change, and the blocked state of the second infrared ray in the pickup link changes, the vending machine determines the fault type of the vending machine as a delivery port fault. Or, when the blocked state of the first infrared ray in the pickup link changes, and the blocked state of the second infrared ray in the pickup link does not change, the vending machine determines the fault type of the vending machine as a second infrared device fault. Or, when the blocked state of the first infrared ray and the second infrared ray in the pickup link do not change, the vending machine sends a pickup reminder and / or determines the fault type of the vending machine as a pickup port abnormality.

[0062] In this way, in the picking link, if the blocked state of the first infrared ray does not change, and the blocked state of the second infrared ray changes, since the premise of entering the picking link is that the first infrared ray is blocked, if the first infrared device continues to remain blocked but the second infrared ray changes from unblocked to blocked, and then changes back to unblocked, it means that the picking is not completed, foreign objects are retained, or the first infrared device is faulty. At this time, the fault type is determined to be a delivery port fault. If the blocked state of the first infrared ray changes from blocked to unblocked, and the blocked state of the second infrared ray does not change and remains unblocked or blocked, it means that the second infrared device is faulty at this time. Since the door body is controlled by the second infrared ray, personal injury is likely to occur at this time. If the blocked states of the first infrared ray and the second infrared ray do not change in the picking link, the first infrared ray remains blocked, and the second infrared ray remains unblocked or blocked, it means that the second infrared device is faulty and foreign objects are retained, the first infrared device and the second infrared device are faulty, or the user deliberately does not pick up the goods after purchasing them, and the picking port is determined to be abnormal.

[0063] Optionally, the vending machine sends a pickup reminder and / or determines that the fault type of the vending machine is an abnormal pickup port, including: the vending machine sends a pickup reminder. When the reminder duration of the pickup reminder is greater than the first duration, and the blocked state of the first infrared ray and the second infrared ray in the pickup link has not changed, the vending machine determines that the fault type of the vending machine is an abnormal pickup port. Specifically, the value range of the reminder duration is [8min, 10min].

[0064] In this way, the blocked states of the first infrared ray and the second infrared ray do not change during the pickup process, the first infrared ray remains blocked, and the second infrared ray remains unblocked or blocked, which means that the second infrared device is faulty and foreign objects are retained, the first infrared device and the second infrared device are faulty, or the user deliberately does not pick up the goods after purchasing them. In this case, the user will be reminded to pick up the goods as soon as possible. If the reminder time exceeds the reminder duration, it is determined that the fault is an abnormality at the pickup port.

[0065] Optionally, after the vending machine determines the transition of the blocked state of the first infrared ray and / or the second infrared ray, the method further includes: the vending machine determines that the vending machine is operating normally according to the transition of the blocked state of the first infrared ray and / or the second infrared ray.

[0066] In this way, according to the transition of the shielding state of the first infrared ray and / or the second infrared ray, it can be determined that the vending machine operates normally.

[0067] Optionally, the vending machine determines that the vending machine is operating normally based on changes in the blocked state of the first infrared ray and / or the second infrared ray, including: when the blocked state of the first infrared ray changes in the delivery link, the vending machine determines that the vending machine is operating normally based on changes in the blocked state of the first infrared ray and the second infrared ray in the pickup link.

[0068] In this way, if the blocked state of the first infrared ray changes in the delivery link, from unblocked to blocked, it means that the delivery enters the pickup link normally. At this time, according to the change of the blocked state of the first infrared ray and the second infrared ray, it is determined whether the vending machine works normally in the pickup link.

[0069] Optionally, the vending machine determines that the vending machine is operating normally according to a change in the blocked state of the first infrared ray and the second infrared ray in the pickup link, including: when the blocked state of the first infrared ray and the second infrared ray in the pickup link changes, the vending machine determines that the vending machine is operating normally.

[0070] In this way, if the vending machine delivers goods normally and enters the pickup stage, the first infrared ray changes from being blocked to being unblocked, and the second infrared ray changes from being unblocked to being blocked and then to being unblocked, which means that the pickup stage is normal, and the conclusion is drawn that the vending machine is working normally.

[0071] Optionally, after the vending machine determines the fault type of the vending machine, the method further includes: the vending machine reports the fault type. The vending machine performs a normal pickup process according to the fault type, or keeps the door open.

[0072] In this way, after the vending machine determines the fault type, it reports the fault type, which is conducive to timely reminder of maintenance. After that, it supports the normal pickup process or keeps the door open according to the fault type, which is conducive to reducing the risk of personal injury during the user's pickup process. It is conducive to making up for the disadvantage of low-cost infrared equipment that does not have fault self-detection and improving the safety of vending machines.

[0073] Optionally, the vending machine performs a normal pickup process or keeps the door open according to the fault type, including: when the fault type is a delivery port fault, the vending machine performs a normal pickup process. Or, when the fault type is a second infrared device fault or an abnormality in the delivery port, the vending machine keeps the door open.

[0074] In this way, if the delivery port fails, there will be no risk of personal injury to the user during the pickup process, and the normal pickup process can be performed. If the second infrared device fails or the pickup port is abnormal, the pickup process continues to close the door, which may make the door switch unable to match the user's pickup process. The risk of personal injury to the user during the pickup process is high. Keeping the door open is conducive to reducing the risk of personal injury to the user during the pickup process. This is conducive to making up for the disadvantage of low-cost infrared equipment that does not have fault self-detection and improving the safety of the vending machine.

[0075] Optionally, the method further includes: the vending machine determines the shielding state of the first infrared ray and / or the second infrared ray. The vending machine determines the fault type of the vending machine according to the shielding state of the first infrared ray and / or the second infrared ray, and controls the opening and closing state of the door.

[0076] In this way, the fault type of the vending machine can be determined based on the blocking state of the first infrared ray and / or the second infrared ray, and the opening and closing state of the door can be controlled, which helps to make up for the disadvantage that low-cost infrared equipment does not have fault self-detection and improve the safety of the vending machine.

[0077] Optionally, the vending machine determines the fault type of the vending machine according to the shielding state of the first infrared ray and / or the second infrared ray, and controls the switch state of the door body, including:

[0078] When the blocked state of the first infrared ray is cleared, and the blocked state of the second infrared ray is cleared, the vending machine determines that the pickup is finished and controls the door to close. Or,

[0079] When the first infrared ray is blocked and the second infrared ray is blocked, the vending machine determines that the vending machine is normal or the fault type of the vending machine is abnormal door blocking according to the door blocking duration. In the case of abnormal door blocking, the vending machine controls the door to remain open. Or,

[0080] When the first infrared ray is blocked and the second infrared ray is blocked, the vending machine determines that the vending machine is normal or abnormal according to the pickup time. In the case of abnormal pickup, the vending machine sends a receipt reminder and determines that the vending machine is normal or the fault type of the vending machine is abnormal door blocking according to the door blocking time. In the case of abnormal door blocking, the vending machine controls the door to remain open. Or,

[0081] When the blocking state of the first infrared ray is blocked and the blocking state of the second infrared ray is unblocked, the vending machine determines that the vending machine is normal or the pickup is abnormal according to the pickup time. In the case of abnormal pickup, the vending machine sends a receipt reminder and counts the abnormal pickup time to obtain the abnormal time. The vending machine determines that the vending machine is normal or the fault type of the vending machine is abnormal delivery port according to the abnormal time.

[0082] In this way, if the first infrared ray is unblocked and the second infrared ray is unblocked, it means that the goods are picked up normally and the goods have been taken out. At this time, the door is closed to complete the normal picking process. If the first infrared ray is unblocked and the second infrared ray is blocked, it means that the goods have been taken away but not taken out of the delivery port. According to the length of time the door is blocked, it is determined that the vending machine is normal or the fault type of the vending machine is abnormal door blockage. In the case of abnormal door blockage, keeping the door open is conducive to timely reminding users to pick up goods and reducing the risk of personal injury during the user's picking process. If the first infrared ray is blocked, and the second infrared ray is blocked, it means that the goods have not been taken away and are still being picked up or the picking up is abnormal. The vending machine is determined to be normal or abnormal according to the picking up time. If the picking up is abnormal, the user is reminded to pick up the goods, and the vending machine is determined to be normal or the fault type of the vending machine is abnormal door blocking according to the door blocking time. At this time, if the door blocking is abnormal, the door remains open, which is conducive to timely reminding the user to pick up the goods and reducing the risk of personal injury during the user's picking up process. If the first infrared ray is blocked, and the second infrared ray is unblocked, it means that the goods have not been taken away or the picking up is abnormal. If the picking up is abnormal, the user is reminded to pick up the goods, and the vending machine is determined to be normal or the fault type of the vending machine is abnormal delivery port according to the abnormal duration, which is conducive to better determining whether the delivery is faulty or whether the user's picking up is overtime, and reminding the user to complete the picking up process in time. In this way, it is conducive to making up for the disadvantage that low-cost infrared equipment does not have fault self-detection and improving the safety of vending machines.

[0083] Specifically, the vending machine determines that the vending machine is normal or the fault type of the vending machine is abnormal door blockage according to the door blockage duration, including: when the door blockage duration is greater than the first duration, the vending machine determines that the fault type of the vending machine is abnormal door blockage. Or, when the door blockage duration is less than or equal to the first duration, the vending machine determines that the vending machine is normal. More specifically, the value range of the first duration is [8min, 10min].

[0084] In this way, if the door is blocked for a long time, it is judged as abnormal, and if the door is blocked for a short time, the vending machine is judged to be normal. This is conducive to more accurately controlling the door to remain open or closed, reducing the risk of personal injury during the user's pickup process. It is conducive to making up for the disadvantage of low-cost infrared equipment that does not have fault self-detection and improving the safety of vending machines.

[0085] Specifically, the vending machine determines that the vending machine is normal or abnormal according to the pickup time, including: when the pickup time is greater than the second time, the vending machine determines that the pickup is abnormal. Or, when the pickup time is less than or equal to the second time, the vending machine determines that the vending machine is normal. More specifically, the value range of the second time is [1min, 2min].

[0086] In this way, if the pickup time is long, it is judged as abnormal, and if the pickup time is short, it is judged as normal. This is conducive to more accurately controlling the door to remain open or closed, reducing the risk of personal injury during the user's pickup process. It is conducive to making up for the disadvantage of low-cost infrared equipment that does not have fault self-detection and improving the safety of vending machines.

[0087] Specifically, the vending machine determines that the vending machine is normal or the fault type of the vending machine is a delivery port abnormality according to the abnormality duration, including: when the abnormality duration is greater than the third duration, the vending machine determines that the fault type of the vending machine is a delivery port abnormality; or when the abnormality duration is less than or equal to the third duration, the vending machine determines that the vending machine is normal. More specifically, the value range of the third duration is [8min, 10min].

[0088] In this way, if the duration of the abnormal pickup is long, the delivery port is judged to be abnormal, and if the duration of the abnormal pickup is short, it is judged to be normal. This is conducive to more accurately controlling the door to remain open or closed, reducing the risk of personal injury during the user's pickup process. It is conducive to making up for the disadvantage of low-cost infrared equipment that does not have fault self-detection and improving the safety of vending machines.
