Building device for vehicular sensor network platform

Abstract

The invention provides a building device for a vehicular sensor network platform, which belongs to the technical field of automobiles and solves the problem of difficulty in management of sensor platforms in the prior art. The device comprises a plurality of sensors, a plurality of CAN (controller area network) bus communication modules of sensor nodes, a sensor gateway node and a monitoring service center host. The sensors are arranged in vehicles, the CAN bus communication modules of the sensor nodes are correspondingly connected with the sensors, the sensor gateway node is connected with the CAN bus communication modules of the sensor nodes by a CAN bus, each CAN bus communication module of the sensor node consists of a signal conditioning circuit, a node controller, a CAN controller and a CAN transceiver, each signal conditioning circuit is connected with the corresponding sensor, each node controller is connected with the corresponding signal conditioning circuit, each CAN controller is connected with an SPI (serial peripheral interface) of the corresponding node controller, each CAN transceiver is connected with the corresponding CAN controller, the sensor nodes can collect parameter signals detected by the sensors when the vehicles run, and the sensor gateway node can organize and coordinate data exchange between the internal CAN network of each vehicle and the external. The building device for the vehicular sensor network platform brings convenience for managing the networked sensor platform.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to a device for building a vehicle-mounted sensor network platform. Background technique [0002] The car is a typical multi-sensor platform, which contains various sensors such as temperature, pressure, flow, position, speed, gas concentration, knock, speed and acceleration. The application of multi-sensor platform can realize the measurement of multi-parameters more conveniently. and multi-object control, as well as the sharing of data information. In order to meet people's requirements for vehicle safety, handling and comfort, more and more electronic systems are integrated on the vehicle. With the development of automotive electronics technology and the increase in the number of automotive sensors, in order to reduce the wiring harness in the car, better manage the sensors, and improve the reliability and real-time performance of sensor data transmission in the car, the netwo...

AI Technical Summary

Problems solved by technology

The vehicle-mounted terminal can realize multiple functions, but there are the following deficiencies: 1. On the basis of better management of sensors, there is no more attention to reducing the wiring harness in the vehicle; 2. The vehicle-mounted terminal has complicated steps to realize multiple functions together , occupying too much memory, it is easy to cause crashes and other situations; 3. The function of the control unit used in the vehicle terminal has certain restrictions on the realization of common transmission of all sensors
