[0024] The vehicle-mounted terminal is an STM32 series single-chip microcomputer or a PLC controller; and the wireless communication device is a wireless transceiver or a Bluetooth communicator.
[0025] An electronic coordinate card is arranged on each parking position of the trailer, and the electronic coordinate card is arranged in electrical connection with the wireless signal transmitting end, so as to combine the position of the trailer with the parking position and further determine the specific position of the trailer.
[0026] The working principle of the intelligent matching and docking system of the drop and pull trailer based on the wireless communication technology in the embodiment of the utility model is as follows: based on the integrated control of the vehicle-mounted terminal, cooperating with multiple types of functional components and the wireless communication device, the tractor can accurately and quickly identify a matching trailer from a plurality of trailers to be selected, and quickly establish a wireless communication connection between the tractor and the matching trailer, so as to greatly improve the utilization rate of the vehicle and the overall transportation efficiency, ensure the coherence and accuracy of vehicle transportation, and even in the scene of matching multiple trailers at the same time, the operation can be carried out efficiently and orderly.
[0027] Since the drop and pull transport can rely on the equipment advantage of vehicles with good compatibility and scalability, there is a higher requirement for the efficiency and accuracy of the matching docking between the tractor and the trailer, especially for long-distance transport and cold chain transport. The matching docking efficiency in the early stage will directly affect the cargo transport process.
[0028] In the overall scheme, the vehicle terminal is arranged in the tractor, which is used to control the wireless communication device to receive the wireless signal of a specific frequency band sent by the trailer to match the corresponding trailer, and control the signal strength monitoring equipment to judge the specific distance parameter of the tractor and the trailer according to the received wireless signal strength; the vehicle terminal includes a wireless communication module, a central processing module, an alarm module and a display module; the wireless communication module is built-in with a wireless communication device, including a wireless signal receiving end and a wireless signal transmitting end arranged in cooperation, the wireless signal receiving end is arranged in the tractor, and the wireless signal transmitting end is arranged in the trailer, so that the tractor and the trailer establish stable connection through the wireless communication module and carry out data interaction; the alarm module is used to trigger the alarm mechanism when abnormal data is detected; the display module is used to display real-time temperature and humidity data on the vehicle terminal, which is convenient for the driver to check; the temperature and humidity monitoring equipment is arranged in the trailer, which is used to monitor the specific temperature and humidity parameters of the trailer; the signal strength monitoring equipment is used to monitor the wireless signal strength received by the vehicle terminal, and then judge the specific distance parameter of the tractor and the trailer according to the wireless signal strength and fine-tune the driving direction of the tractor.
