Embodiment 1

[0014] Mine safety production monitoring method, using CAN bus to form a peer-to-peer inter-layer field bus network. Using priority arbitration technology, when bus access conflicts occur, high-priority information can still be sent, which is more suitable for data processing in mines. For systems with high requirements for transmission and real-time control, the CAN bus communication protocol and interface are simple, the transmission rate is high, it has a variety of error detection methods, and it has strong anti-interference. It encodes communication data blocks and easily realizes point-to-point communication. The length of the data segment is up to 8 bytes, which can meet the general requirements of control commands, working status and test data. For traditional mine reconstruction, only the RS-485 nodes need to be replaced by CAN nodes, and the information in the original system The transmission interface, monitoring system software and workstation are respectively repla...

Abstract

The invention provides a mine safety production monitoring method. Almost all existing monitoring systems use their own dedicated communication protocols, so that it is difficult to find two compatible systems. According to the mine safety production monitoring method provided by the invention, a peer-to-peer inter-layer field bus network is formed by adopting a CAN bus, the priority arbitration technology is adopted, the information with high priority can still be transmitted in the case of a bus access conflict, the length of a data segment of the CAN bus is 8 bytes at most, the general requirements of control commands, working states and test data can be met, for the traditional mine reconstruction, an RS-485 node is just replaced with a CAN node, an information transmission interface,monitoring system software and a workstation in the original system are replaced with a CAN interface adapter, monitoring system software applicable to a CAN communication protocol and a CAN-based workstation separately, a monitoring host can also be connected with a server to access a local area network and the Internet so as to implement remote browsing and control. The mine safety production monitoring method provided by the invention is applied to mine safety production monitoring.

Description

Technical field: [0001] The invention relates to a mine safety production monitoring method. Background technique: [0002] my country's mine safety production monitoring system has experienced a comprehensive monitoring process from scratch, from simple to complex, from integrated machine to network, from secondary network to multi-level network. After more than ten years of application, the mine safety production monitoring system has played a significant role in my country's coal mine safety production and modern management. However, since the existing monitoring systems almost all use their own dedicated communication protocols, it is difficult to find two mutually compatible systems. At present, the compatibility of the information transmission system has become a restrictive factor for the bureaus and mines equipped with the monitoring system to further expand the system functions. Therefore, finding a way to solve the system compatibility problem is of great signifi...
