Whether the monitoring of loading case switch door for solving the control is with high costs, not accurate scheduling problem, this application provides a switch door supervisory equipment of commodity circulation vehicle to guarantee supervisory equipment's precision and stability. For example, the door opening and closing monitoring device can be used on the doors of logistics vehicles and can also be used on the doors of containers of trains, airplanes and ships. The following description is mainly made of the door opening and closing monitoring device of the logistics vehicle.
The present disclosure provides a door opening and closing monitoring device for a logistics vehicle, which is explained in detail with reference to the following embodiments. Fig. 1 is a schematic structural diagram of a door opening and closing monitoring device of a logistics vehicle according to an embodiment of the present application. As shown in fig. 1, the door opening and closing monitoring apparatus includes: signal monitoring unit 100, signal transmission unit 200.
The signal monitoring unit 100 and the signal transmitting unit 200 are both disposed on a gate post of the logistics vehicle, and the signal monitoring unit 100 is disposed on one side of the gate post close to the inner wall of the compartment. The door post is used for fixing and supporting a vehicle door and is divided into a door post on the inner wall of the carriage and the door post, and the signal monitoring unit 100 and the signal sending unit 200 can be arranged on the door post of the logistics vehicle in a sticking mode. Since the vehicle has a plurality of doors, in order to avoid misunderstanding, it is specifically explained herein that the doors mentioned in the present application are compartment doors of a vehicle compartment.

2. The apparatus of claim 1, wherein the signal monitor comprises: a switching device and a monitoring chip;
one end of the switch device is grounded, and one end of the telescopic mechanism is used for being abutted against the other end of the switch device when the vehicle door is closed, so that the other end of the switch device is communicated with the input end of the monitoring chip; the output end of the monitoring chip is the output end of the signal monitor, and the other end of the switch device is the detection end of the signal monitor.
3. The apparatus of claim 2, wherein the switching device is a metal dome.
4. The apparatus of claim 1, wherein the telescoping mechanism is an L-shaped swing link, one end of the telescoping mechanism being a long arm of the L-shaped swing link and the other end of the telescoping mechanism being a short arm of the L-shaped swing link.
5. The apparatus of claim 4, wherein the distal end of the long arm is further provided with a latch portion facing the inside of the housing of the signal monitor, and a locking portion matching the latch portion is provided in the housing, and the long arm is retracted in the housing by the locking portion and the latch portion.
6. The apparatus according to claim 5, wherein a switch operating portion associated with the locking portion is further provided on an outside of the housing to allow the locking portion to be engaged with or disengaged from the catch portion by the switch operating portion.
7. The apparatus of claim 1, wherein the signal transmission unit comprises: the communication antenna is connected with the processing module, the communication module and the communication module; the input end of the signal sending unit is the input end of the processing module, and the processing module is connected with the communication module, so that the processing module transmits the vehicle door state signal to the server sequentially through the communication module and the communication antenna.
8. The apparatus of claim 7, wherein the signal transmission unit further comprises: the positioning module is connected with the processing module.
9. The apparatus of claim 8, wherein the positioning antenna is disposed outside the housing of the signal transmission unit for fixing to an outside of the vehicle compartment.
10. The apparatus of claim 7, wherein the signal transmission unit further comprises: and the processing module is connected with the display module.
