Embodiment Construction

[0019] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0020] refer to Figure 1-4 , a kind of CAN equipment automatic identification method described in this specific embodiment, described method comprises:

[0021] The query host sends a voltage query signal with a certain pulse width through the query line;

[0022] After the I / O module along the line detects the query signal sent by the host, it replies the voltage signal of a certain pulse width to the query host through the query line, opens the CAN bus to receive the new address program and turns on the electronic switch, and switches itself to the pulse monitoring mode for the query line;

[0023] After the query host receives the reply signal from the I / O module, it sends the communication address to the I / O module through the CAN bus, determines the status of the module that is queried this time and records it, and then sends the query signal to q...

Abstract

The present invention relates to a CAN device automatic identification method and a mine belt protection system. The mine belt protection system comprises a query host, a plurality of input and output modules (I / O modules) and a terminal; the query host sends query signals; when retrieving an I / O module, the query host automatically sends a communication address to the I / O module through a CAN bus; and therefore, communication address automatic distribution of the plurality of I / O modules can be realized, and data communication can be carried out. With the CAN device automatic identification method and the mine belt protection system of the invention adopted, devices along a line can carry out automatic remote communication without manual address coding required. The CAN device automatic identification method and the mine belt protection system are simple to use, reliable in usage and can assist in reducing maintenance time and cost.

Description

technical field [0001] The invention relates to the technical field of mine acquisition systems, in particular to a CAN device automatic identification method and a mine belt protection system. Background technique [0002] At present, most of the device communication is based on the master device searching for heavy devices, and then configuring the settings. On-site use and debugging are complicated and cumbersome. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a CAN device automatic identification method and a mining belt protection system, which are simple in structure and easy to operate. You only need to connect the devices with cables in order to communicate normally, without debugging and configuration, which greatly simplifies installation, debugging and configuration, reduces failure rate, and improves work efficiency. [0004] The technical scheme that the present invention adopts for solving the ab...
