[0044] Embodiment one,

[0045] Referring to Figures 1-7 , in the embodiment of the application, a lock falling detection device 10 is applied to a parking lock, and the lock falling detection device 10 comprises a controller 11, a parking lock state detection module 12 in communication connection with the controller 11, the parking lock state detection module 12 comprising a signal transmitter 121 and a signal receiver 122, the parking lock state detection module 12 being fixedly arranged on the parking lock, and the controller 122 being in communication connection with an alarm device 13.

[0046] In an implementation scenario of the present application, the parking lock generally comprises a lifting device and a base, the signal transmitter 121 is arranged on the lifting device side or the base side of the parking lock, and the signal receiver 122 is arranged on the lifting device side or the base side of the parking lock.

[0047] It should be noted that the parking lock type that can be carried by the lock falling detection device 10 provided by the present application includes but is not limited to: U-shaped swing arm parking lock, T-shaped swing arm parking lock, tripod type lifting parking lock, and flat plate parking lock, and other devices widely installed on parking spaces for controlling vehicles. The lifting device refers to the component of the parking lock that performs the lifting motion, and the base refers to the component of the parking lock that is relatively fixed in position, for example, in the U-shaped swing arm parking lock, the lifting device refers to the U-shaped swing arm component, and the base refers to the parking lock base with a fixed lower end; in the tripod type lifting parking lock, the lifting device refers to the tripod lifting component, and the base refers to the parking lock base accommodating the tripod at the lower end; in the flat plate parking lock, the lifting device refers to the upwardly turned flat plate component, and the base refers to the parking lock base accommodating the flat plate at the lower end. The U-shaped swing arm parking lock or the T-shaped swing arm parking lock is taken as an example to illustrate the lock falling detection device 10 provided by the present application.

[0048] In an implementation scenario of the present application, the lock falling detection device 10 further comprises a counter 17 in communication connection with the controller 11 and the parking lock state detection module 12, the counter 17 receives the triggering times of the parking lock state detection module 12, and sends the counting result to the controller 11.

[0049] When a vehicle enters the parking space, the parking lock can receive a lock falling instruction, perform a lock falling operation according to the lock falling instruction, and when the lock falling is completed, the current position of the parking lock swing arm can be detected by the lock falling detection device 10 to determine whether the lock falling is completed, if the lock falling is completed, the vehicle can be allowed to enter, and if the lock falling is not completed, for example, in the lock falling process, or the lock falling fails due to a fault or other external force, at the same time, the triggering times of the detection module can be recorded by the counter, and the actual stay angle of the swing arm can be calculated by the controller according to the triggering times, so as to determine whether the parking lock is lowered to the position or raised to the position. If the lock falling fails, is not lowered to the position, or is not raised to the position, an alarm information can be outputted to prompt the user, so as to avoid the collision between the user and the parking lock that is not completely locked, and cause the vehicle damage. Through the lock falling detection device, the real-time monitoring and feedback of the parking lock state can be realized, the complete lock falling of the parking lock is ensured, the safety accidents or resource waste problems caused by the incomplete lock falling are effectively prevented, and the efficiency of the parking lot management and the user experience are improved.

[0050] In an implementation scenario of the present application, if each parking space in the XX large commercial center is installed with the parking lock detection device 10, when a vehicle is detected to enter, the parking lock detection device 10 can be used to detect whether the parking lock of the current parking space is lowered, if yes, the vehicle can be allowed to enter, otherwise, an alarm information is output. At the same time, the trigger number of the detection module can be recorded by the counter, and the actual stay angle of the swing arm can be calculated by the controller according to the trigger number, so as to determine whether the parking lock is lowered to the position. When the parking lock is not lowered to the position, the user can be prompted to stop entering the parking space in time. Through the high precision and reliability of the parking lock detection device 10, the safety hidden danger caused by incomplete lowering of the parking lock can be effectively prevented, and the overall safety and user experience of the parking lot are improved.

[0051] The controller 11 can be an MCU, a single-chip microcomputer or the like, which can be arranged in a PCB circuit board and connected with other modules through a circuit to realize electrical connection and signal transmission between the modules.

[0052] In the embodiment of the present application, the parking lock state detection module 12 can be any one of a photoelectric detection sensor, an ultrasonic detection sensor and an infrared sensor.

[0053] Referring to Figure 2 In an embodiment of the present application, the parking lock state detection module 10 can be a reflective parking lock state detection module or a transmissive parking lock state detection module. When the parking lock state detection module 12 is a reflective parking lock state detection module, the signal transmitter 121 and the signal receiver 122 are arranged on the swing arm side or the base side of the parking lock swing arm 20 in the axial direction, the signal of the signal transmitter 121 is reflected back to the signal receiver 122 through the reflecting sheet 123, the reflecting sheet 123 includes a plurality of first reflecting areas 1231 and second reflecting areas 1232 arranged alternately, the signal receiver does not generate a trigger signal when the signal of the signal transmitter 121 irradiates the first reflecting area, and the signal receiver generates a trigger signal when the signal of the signal transmitter irradiates the second reflecting area.

[0054] Taking the photoelectric sensor as an example, the signal transmitter 121 emits light to the parking lock swing arm 20, the parking lock swing arm 20 reflects the light back to the signal receiver 122, and the signal receiver 122 detects the amount of reflected light to determine the position of the parking lock swing arm 20, thereby determining the state of the parking lock.

[0055] Similarly, referring to Figure 3When the parking lock state detection module 12 is a transmissive parking lock state detection module, the signal transmitter 121 and the signal receiver 122 are oppositely arranged on the sides of the parking lock swing arm 20 and the base, and the signal of the signal transmitter 121 is transmitted to the signal receiver 122 through the shielding sheet 123. The shielding sheet 123 comprises a plurality of shielding areas and hollow areas arranged alternately. When the signal of the signal transmitter 121 irradiates the shielding areas, the signal receiver 122 does not generate a trigger signal. When the signal of the signal transmitter 121 passes through the hollow areas, the signal receiver 122 generates a trigger signal. For example, when the photoelectric sensor is taken as an example, the parking lock swing arm 20 will shield or change the light intensity when rotating, and the signal receiver 122 can detect the position of the parking lock swing arm 20 according to the change of the light, so as to determine the state of the parking lock.

[0056] Referring to Figure 4 , Figure 5 respectively, a structural diagram of a reflecting sheet is provided, and the signal transmitter 121 and the signal receiver 122 are arranged on the same side of the axial direction of the parking lock swing arm 20. Figure 4 In the figure, the reflecting sheet can be a fan-shaped structure, one end of the parking lock swing arm 20 is provided with a rotating shaft 21, the rotating shaft 21 can reciprocate along the arrow direction in the figure, and the reflecting sheet 123 is assembled on the rotating shaft 21 and can rotate with the rotating shaft 21. Wherein, the parking lock swing arm 20 is in a descending state, that is, at this time, the parking lock is in a locked state. The reflecting sheet 123 can comprise a first reflecting area 1231 and a second reflecting area 1232 arranged alternately. When the signal of the signal transmitter 121 irradiates the first reflecting area 1231, the signal receiver 122 does not generate a trigger signal. At this time, the first reflecting area 1231 can optionally comprise but is not limited to a diffuse reflecting surface or a hollow area, and the two structures will not reflect the light back to generate a trigger signal of the signal receiver 122. When the signal of the signal transmitter 121 irradiates the second reflecting area 1232, the signal receiver 122 generates a trigger signal. At this time, the second reflecting area 1232 can optionally comprise but is not limited to a mirror surface, and the mirror surface will reflect the light back to generate a trigger signal of the signal receiver 122.

[0057] By alternately arranging the first reflecting area 1231 and the second reflecting area 1232, the counter 17 can be facilitated to count, so as to determine whether the parking lock is completely descended or completely ascended. For example, Figure 4 In the figure, the fan-shaped reflecting sheet can be 90 degrees, which can be provided with 10 second reflecting areas. When completely descending, the number of received and transmitted signals can be 10 times, at this time, the vehicle can be parked. If the counter only counts 5 times, it means that it has only descended to half, at this time, the descending is not completed, and the vehicle cannot be parked, and a prompt information can be output.

[0058] Figure 5 In the embodiment, the shaft side view of the parking space lock swing arm is shown, that is, the shape of the reflecting sheet 123 when it is unfolded. Taking the case where the signal transmitter 121 and the signal receiver 122 are installed on the same side of the shaft of the parking space lock swing arm 20 as an example, one end of the parking space lock swing arm 20 is provided with a rotating shaft 21, the rotating shaft 21 can reciprocate along the direction of the arrow in the figure and drive the parking space lock swing arm 20 to rotate, and the reflecting sheet 123 can be an arc-shaped sheet structure and is arranged on the circumferential side of the parking space lock swing arm 20. When the parking space lock swing arm 20 rotates, it can rotate from one end to the other end of the reflecting sheet 123. Since the reflecting sheet 123 includes a plurality of first reflecting areas 1231 and second reflecting areas 1232 arranged alternately, the signal receiver does not generate a trigger signal when the signal transmitter 121 irradiates the signal to the first reflecting area, and the signal receiver generates a trigger signal when the signal transmitter irradiates the signal to the second reflecting area. Therefore, in the process of rotation, the signal transmitted by the signal transmitter 121 can gradually pass through the first reflecting area 1231 of the reflecting sheet 123, and the counter 17 can count the number of times the signal transmitted by the transmitter 121 is received.

[0059] In the embodiment, the first reflecting area 1231 and the second reflecting area 1232 are arranged alternately, which facilitates the counting of the counter 17, so as to determine whether the parking space lock is completely lowered or completely raised. Figure 5 In the embodiment, the reflecting sheet can be an arc-shaped sheet structure and is arranged on the circumferential side of the parking space lock swing arm 20, which can be provided with 10 second reflecting areas. When it is counted to 10 times during the lowering, it indicates that the lowering is completed and the vehicle can be parked. If the counter only counts 5 times, it indicates that it is only lowered to half, at this time, the lowering is not completed and the vehicle cannot be parked, and a prompt information can be output.

[0060] It should be noted that for the case where the signal transmitter 121 and the signal receiver 122 are installed on the two sides of the shaft of the parking space lock swing arm 20, the shielding sheet can be arranged according to the structure and installation position of the reflecting sheet 123 in the above Figure 4 and Figure 5 embodiments, and the present application will not be described again. Similarly, the shielding sheet is provided with a plurality of shielding areas and hollow areas arranged alternately, the signal receiver 122 does not generate a trigger signal when the signal transmitter 121 irradiates the signal to the shielding area, and the signal receiver 122 generates a trigger signal when the signal transmitter 121 irradiates the signal to the hollow area. The counter 17 can count the number of times the received transmitted signal is counted, so as to determine whether the parking space lock swing arm 20 is completely lowered or completely raised.

[0061] In the embodiment of the present application, the alarm device 13 comprises a reporting module and an alarm module; the reporting module sends the alarm signal to the server when receiving the alarm signal; the alarm module comprises at least one of a light alarm device and a sound alarm device. When it is detected that the parking lock is not completed or fails to lock, in order to avoid the safety hazard caused by the user still driving the vehicle to enter, the alarm device 13 can output an alarm signal, for example, different colors of light or different flashing modes of light are used to display different parking lock states to prompt the user, for example, “red indicates that the locking fails to stop driving in”, “green indicates that the locking is completed and can drive in”, “yellow indicates that the locking is in progress, wait to drive in” and the like. Similarly, the user can also be prompted by inputting sound or voice. Or sound and light can be prompted at the same time.

[0062] In the embodiment of the present application, the device further comprises a communication module 14 in communication connection with the controller, and the controller 11 is connected with the parking lock management platform 200 through the communication module 14. When the locking fails, the parking lock can be connected with the parking lock management platform 200 through the communication module, and the state of the parking lock is sent to the parking lock management platform 200, so that the user or the on-site management personnel is notified of the current state of the parking lock through the parking lock management platform 200, so as to timely process. Or, it can also be directly connected with the client held by the user to directly notify the user of the current state of the parking lock, so as to realize the sending of the alarm signal.
