Two-way CAN bus vehicle mounted remote communicating and satellite positioning system

Abstract

The invention relates to a vehicle system with double CAN bus remote communication and satellite positioning in the electromechanical equipment technical field, wherein, two double CAN bus transceivers are connected to a central controller through data signal lines to realize the transmission of vehicle system condition signals to the central controller; the central controller is connected to a remote communication and positioning module through the data signal lines and the control signal lines to realize the collection of positioning information, the control of remote communication function and the remote communication of data; a serial data memory is connected to the central controller through the signal lines to realize the storage of the identity recognition information of the monitoring objects, the storage of the sampling period and the server IP address; a level translator is connected with the central controller to realize the level match between the central controller and the peripheral equipment; SIM card is arranged in the SIM card holder, GSM antenna and GPS antenna are connected to the remote communication and positioning module to realize remote communication and positioning. The invention can meet the needs of remote and wireless real-time monitoring of the working status of engineering machinery and geographic coordinate information.

Description

technical field [0001] The invention relates to a positioning system, in particular to a dual-channel CAN bus remote communication and satellite positioning vehicle system, which belongs to the technical field of electromechanical equipment. Background technique [0002] As the control system based on CAN bus is widely used in construction machinery, it is a very effective and feasible method to monitor the diesel engine, hydraulic system and other working conditions of construction machinery in real time by collecting CAN bus data. The GPS module can receive the geographic location information and time information provided by the Global Positioning System GPS for free. General Packet Radio Service (GPRS) is a data transmission technology based on the Global System for Mobile Phones (GSM), which has the functions of "real-time online", "according to the volume", "quick login", "high-speed transmission", "free switching "The advantages have been widely used in various long-d...

AI Technical Summary

Problems solved by technology

There is only one CAN bus interface, which cannot meet the needs of dual-channel CAN bus data acquisition for many construction machinery; [2]

Using independent GPS module and GSM module increases system complexity and hardware cost; [3]

Using a single-chip microcomputer as the central processing unit, the on-chip resources are not enough, such as the serial port cannot meet the needs, a serial port switching circuit needs to be added, the memory cannot meet the needs, and the off-chip memory needs to be expanded, there is no on-chip CAN bus controller, and external expansion is required; [ 4]

The monitoring parameters are single and cannot be adjusted remotely and flexibly
