Control Local area network (Controller area network) is the one of the widest application for the total line in the world. As the mini-controller communication of the automotive environment, it can change the information between the ECUs installed on the vehicles, and become to the automotive electronic control network. CAN is almost the obligatory technology method adopted in automotive design field.
CAN module device is an intelligent electronic control device which can achieve communication data transferred among each electronic control device installed in the automobile, thereby, it can make the automobile become a network control system of on-vehicle electronic control device area. Adopt powerful 16-bit micro-controllers with two way, Support protocols of CAN 2.0 A and CAN 2.0B and Developed by the standard protocol SAEJ1939, K-line diagnosis function is available. Meantime, fit for high-speed CAN bus line network as well as low-speed. Good sealing property can used in all kinds of bad conditions.
When electronic control device on-vehicle without CAN function (It can not transfer data communication with other devices If these electronic control device without CAN communication function. The function of device will be reduced, singleness and hard to expand), and can't communicate directly. CAN module device can make the on-vehicle electronic control network system have CAN function. It can transmit all the needed signal among each device and make the electronic control system more powerful.
◆ Two channels of 5V output voltage, can supply 100 ma current.
◆ Two channels of Digital-to-Analog Converter Output,12-bit conversion accuracy.
◆ Four channels of on-off output.
◆ One channel of RPM signal input (magnetic electricity signal).
◆ Eight channels of analog signal input, 12-bit conversion accuracy.
◆ Three channels of on-off input test, to achieve the capture of signals from active and passive sensors.
◆ Port information: one RS232 port, two K-line ports, two CAN bus port.
◆ Achieve the receiving and sending of data information from all nodes on vehicle through the CAN bus line network.
◆ Collect information of each sensor in real time, keep abreast of the running situation from the engine.
◆ System diagnostic.
◆ Various input and output interface, can achieve signal function transferring neatly.
Application condition:
This product has good application in the gas-electric hybrid bus project which developed together with the research institute of The First Automobile factory of China. The main function is to make ECU connect with the CAN bus line via the CAN module. It controls ECU through the data transfer and conversion with TCU, HCU, IC module, etc. CAN module is connected to the water temperature sensor, oil pressure sensor , speed sensors and send the data of sensors and data under the controlling of ECU to TCU,HCU,IC , meanwhile it sends the control function information of TCU and HCU to ECU via CAN module.
