Embodiment Construction

[0026] The technical solution of the present invention will be described in further non-limiting detail below in combination with preferred embodiments and accompanying drawings.

[0027] The purpose of the present invention is to disclose a kind of data acquisition system based on CAN bus, which is mainly used in vehicles, factories, buildings, hospitals, cars, ships and aircrafts with CAN network devices, and can collect CAN bus data and satellite data in real time. Position the system data and send it to the remote server. It also has the functions of voice broadcast, information display, voice call, emergency call, video recording and video reading. However, in this embodiment, the data acquisition system based on the CAN bus is applied to the vehicle.

[0028] like figure 1 As shown, the CAN bus-based data collection system of this embodiment includes a data center 1, a satellite positioning system 2, and a data collection terminal 3 that communicates wirelessly with the...

Abstract

The invention discloses a data collection system based on CAN (controller area network) bus comprising a data center, a global positioning system and a data collection terminal, wherein the data collection terminal comprises a microprocessor and a navigation signal receiving module, a CAN communication module, a wireless communication module, a video input device and a storage which are electrically connected with the microprocessor; the navigation signal receiving module is used for receiving signal of the global positioning system and transmitting the signal to the microprocessor; the CAN communication module is used for receiving device signal of the CAN bus and transmitting the received device signal to the microprocessor; the wireless communication module is used for wireless communication with the data center; the video input device is used for collecting video information in real time; the storage is used for storing video information. Site video information is recorded by the video input device in real time, the video information is stored such as in a storage card, the video information can be read by the data center through the wireless communication module, and then real-time operating conditions of a car can be recorded and known.

Description

technical field [0001] The invention relates to a data acquisition system based on CAN bus. Background technique [0002] When the vehicle is running, it will generate a large amount of working condition data, such as engine revolutions, vehicle speed, fuel consumption, oil temperature, oil pressure, brake pressure, exhaust pressure, and status information such as brakes, lights, and doors. It is difficult to find the real-time operation status of the vehicle only by experience and feeling during driving. Therefore, it is particularly important to install a vehicle-mounted electronic system on the vehicle to collect real-time data of the vehicle. The current vehicle-mounted electronic system is widely used. CAN (Controller Area Network, controller local network) bus. CAN bus belongs to the category of field bus. It is a serial communication network that effectively supports distributed control or real-time control. It is a multi-master bus, and the communication medium can ...
