Abstract

The invention discloses a distributed grid electric quantity collector comprising a microprocessor and an interrupt controller which is connected with the microprocessor. The distributed grid electric quantity collector further comprises a power source monitoring chip, display equipment and a clock circuit which are connected with the microprocessor, and an input processing circuit which is connected with the interrupt controller and a CAN bus. The distributed grid electric quantity collector realizes data communication exchange through the CAN bus, and is of high system response speed and high anti-interference capability; the collector has the advantages of high network reliability, high communication band rate and large data transmission quantity; and the collector is simple in structure and convenient to mount and maintain. The system can conveniently achieve functions of real-time monitoring, high-speed data collection, table looking-up and printing, system monitoring and the like.

Description

technical field [0001] The invention belongs to the field of electronic power, and relates to a distributed electric power collector. Background technique [0002] Controller area network CAN (controllerarea network) is a multi-master controller area network technology introduced by German Bosch in the field of modern automotive electronics technology. It can effectively support distributed and real-time control. It was mainly used in automotive internal electronic monitoring and control devices at the earliest. data communication. Because of its high reliability and high real-time performance, it is widely used in industrial field control and other fields. Its outstanding feature is the use of a short frame structure with a maximum of 8 data bytes, short transmission time and high real-time performance; in addition, the CAN protocol cancels the traditional address coding concept and replaces it with lossless priority arbitration based on data block identifiers , which bri...
