Abstract

A drop-and-hook carriage positioning device and method, the device includes a power supply module, a storage module, a detection module, a sensing module, a GPS module, a processing module and an output module. The method is as follows: before the front of the vehicle is separated from the compartment, the power module stores electric energy through frictional electricity generation. When the headstock and the carriage are separated, the headstock records the final position information of the carriage into the storage module. After the front of the car is separated from the compartment, if the compartment does not move, the processing module extracts the last position information of the compartment from the storage module, and the sensor module obtains the status information of the compartment, and sends it to the information center for positioning display through the output module. If the position of the carriage moves, the GPS module starts to work to obtain the latest position information of the carriage and send it to the information center for positioning display. The invention realizes the effective positioning of the position of the compartment when the front of the vehicle is separated from the compartment, and at the same time, the GPS module only works during the movement of the compartment, thereby realizing power saving and environmental protection, and improving the use efficiency of the drop-and-hook compartment.

Description

A device and method for positioning a drop-and-hook carriage

technical field

The invention belongs to the technical field of GPS positioning, in particular to a positioning device and method for drop-and-hook carriages.

Background technique

In the traditional logistics transportation, the front and the carriage are regarded as an independent whole, and the operation mode of "one carriage, one carriage" is widely used. However, with the development of the logistics industry, a new logistics operation mode --- drop and hang logistics has emerged. Drop-and-hook logistics is different from traditional logistics transportation. It breaks the limitation of "one car, one compartment" and realizes the separation of the front and compartments. One front can correspond to multiple compartments. When the vehicle transports the goods to the destination, the head and the compartment are separated. While loading and unloading the goods in this compartment, the front can be spliced with another loaded compartment for transportation, which improves the utilization efficiency of the front and compartment.

The traditional vehicle positioning relies on the GPS equipment installed on the front of the vehicle, and the front and the compartment are connected together for simultaneous positioning. However, in the drop-and-hook logistics mode, after the front of the car and the compartment are separated, the compartment can no longer rely on the front of the car to locate its own position information. At the same time, the compartment itself loses its power supply facilities and is in a state of no electricity. It cannot directly use the GPS device to locate the position of the compartment.
