A Self-diagnosis Based Intelligent Power Distribution Sequencer

Abstract

The invention relates to an intelligent power distribution timing sequence device based on self diagnosis. After the timing sequence device is powered up, 220V alternating current is converted by a power supply circuit into +5V power that can be accepted by a controller. After operates, the controller reads a parameter stored in a data storage circuit firstly and configures the CAN bus node address of the timing sequence device with a bus address configuration circuit. Then, a self-diagnosis circuit is powered up to execute self diagnosis. After a normal state is diagnosed, the timing sequence device enters a power distribution mode to query states. According to different power distribution timing sequence of different vehicle-mounted instrument devices, the power distribution mode and the power distribution timing sequence are stored through the data storage circuit. In the meantime, load voltage, current, and frequency which are acquired by a data acquiring circuit are uploaded to a host computer through a bus communication circuit in order to monitor the load voltage, current, and the frequency parameters in real time. The intelligent power distribution timing sequence device has advantages of fast response speed, a strong anti-interference capability, high signal acquiring precision, and good universality, and provides a new effective solution for unattended power distribution of multipath AC load.

Description

technical field [0001] The invention relates to an intelligent power distribution sequencer based on self-diagnosis, in particular to an intelligent power distribution sequencer which distributes and transmits alternating current to multiple instruments and equipment according to the set sequence requirements. Background technique [0002] With the increase of on-board instruments and equipment in emergency command vehicles, the connection relationship between various instruments and equipment has become increasingly complex, resulting in higher and higher requirements for the power supply and power distribution sequence of instruments and equipment. At present, most of the on-board power distribution is in manual mode, which is cumbersome to operate and cannot meet the timing requirements of various working conditions for instruments and equipment. Moreover, it is impossible to quickly locate and isolate the fault after the power distribution fails, which reduces the intelli...
