In view of the shortcoming such as wiring difficulties, poor scalability, and big cable usage in present mine security monitoring system, this paper puts forward a kind of substation monitoring and control system based on ZIGBEE and CAN. With the core of core, The system collects various measurement data of sensors through the ZIGBEE wireless network, realizes the to collect, and then through the CAN bus to realize the transmission of control commands and data of the up and down machine, and monitor the production parameters and environmental parameters in the coal mine. Experiments show that the monitoring substation is of high real-time performance, good stability, strong expansibility, etc., and can meet the requirements of the coal mine development and mining.

To solve the problem that the safety data in the process of coal mine production are easy to be maliciously tampered with and deleted, a mine consortium blockchain data security monitoring system is proposed. The coal mine consortium blockchain includes supervision department, builds favourable centralized and decentralized production mode, and improves PBFT (Practical Byzantine Fault Tolerance) consensus mechanism to implement practical coal mine safety production. The evaluation shows that the architecture we proposed is more appropriate and efficient for the mine Internet of Things than the traditional blockchain architecture. The Hyperledger Fabric platform is used to build the mine consortium blockchain system to achieve the sensor data reliability, node consensus, safe operation automation management, and major equipment traceability.

The incompatible data information between the various types of ventilation management software and the coal mine safety monitoring system has become a major obstacle to the mine ventilation and safety management informatization. This paper studies the synchronizing integration of the heterogeneous data between the coal mine three-dimensional visualization ventilation system and the security monitoring system, which divides the mine ventilation information into the basic information and the security monitoring real-time information, analyses the transmission characteristics of the real-time monitoring data, explores the conversion of heterogeneous data online communication, and achieves the integration of geometric parameters and various dynamic parameters for the coal mine ventilation system.
