Third Generation of Current Retarder
China and Vietnam's first three-generation eddy current retarder controller (based on the CAN bus communication, SAEJ1939 protocol yards) won the State Intellectual Property Office issued a utility model patent certificate, patent No. ZL200820213160.4. The control system based on CAN bus at home and abroad is the first case, the technology represents the eddy current retarder control of today's technology, the world's highest level.
China and Vietnam the Third Generation of Eddy Current Retarder of the Technical Background:
The first generation of hand-dial switch and a pressure switch direct control of the relay control coil off, there are shortcomings in their own power-3000mA, response to slow, when the work contact arc (spark), no delay between gear.
2nd generation of hand-foot control dial switch hop electronics CP2020 + CP9002 (ABS and speed controller) through CPU control from the electronic controller CP6060 (non-contact) to control the coil off, power consumption 20mA, in addition to the first generation of a weaknesses to improve, but also increase the high current output short-circuit cut off, over-temperature, overload protection. The disadvantage is that too many wires, no communication, no other controller instructions and vehicle operation and sharing of data.
3rd generation 3rd generation of eddy current retarder controller (based on the CAN bus communication, SAEJ1939 protocol yards) in the context of the development of these technologies is divided into front-end module CP9050CAN and back-end module CP9016CAN, two controllers have adopted the United States ATMEL company's built-in CAN controller (CAN2. 0B) 64K core memory AVR microcontroller AT90CAN64. The 3rd generation of eddy current retarder controller (based on the CAN bus communication, SAEJ1939 protocol code) the application of the vehicle braking distance can be further reduced, slippery pavement retarder wagging tail phenomenon improved throttle control and temperature monitoring Alarm function to further improve safety, reduce driver requirements. Fault code feedback to make maintenance easier.
China and Vietnam the Third Generation of Eddy Current Retarder of Innovations:
Based on CAN Bus (SAEJ1939 agreement yards) of the third generation of electrical eddy new products, compared to the second generation of eddy current retarder has made substantial progress in technology. It can receive the control commands on the bus, drive the coil power control switches, winding through the bus for each working state feedback; temperature signal from analog into digital, through the bus, sent to the front-end module CP9050CAN, for retarder Ontology temperature is near the sound and light display, and over-temperature alarm. This will not only receive from the bus on the ABS / ASR interrupt signals, the implementation of retarder interrupt and restart, but also can receive the speed signal for low-speed control; front-end module displays the working state of each stall, with a temperature display, voice alarm, speed control displays, communications status display and other functions; the use of air brake pedal stroke, so that the work ahead of retarder to achieve a more sensitive response to human-machine communication, easy to operate the advanced controller.
