Abstract

The invention belongs to the technical field of rail transit, and particularly relates to a rail transit BMS temperature polling collection technology which comprises a chip, eight bidirectional analog switches are arranged in the chip, and the chip is provided with a plurality of bidirectional analog switches. One ends of the eight bidirectional analog switches are connected with an X0 input port, an X1 input port, an X2 input port, an X3 input port, an X4 input port, an X5 input port, an X6 input port and an X7 input port respectively, and the X0 input port, the X1 input port, the X2 input port, the X3 input port, the X4 input port, the X6 input port, and the X7 input port are respectively connected with the pin 13, pin 14, pin 15, pin 12, pin 1, pin 5, pin 2, and pin 4. The invention adopts a digital switching circuit. The efficiency is improved, limited resources are used for maximum configuration, the technology adopts a polling mode, the resources are integrated, and the power consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a rail transit BMS temperature polling acquisition technology. Background technique [0002] In the rail transit BMS system, in order to improve the safety and stability of the product, it is required to monitor the temperature of a single battery module in the entire system, which requires the system to do more temperature collection points to meet the design requirements, because the resources of the single-chip Limited, using the AD sampling mode to collect temperature can only provide a few temperature samples, occupying the resources of the single chip microcomputer, and the resources are not enough to meet the needs of the entire system. Contents of the invention [0003] The purpose of the present invention is to provide a rail transit BMS temperature polling acquisition technology to solve the problem of insufficient resources and unable to meet the needs of the en...
