WIRELESS SENSOR NETWORK-BASED INTELLIGENT SAFETY MONITORING SYSTEM FOR UNDERGROUND NON-COAL MINE TECHNICAL FIELD The present disclosure relates to the field of wireless monitoring for mine safety, and specifically, to a wireless sensor network-based intelligent safety monitoring system for an underground non-coal mine. BACKGROUND To satisfy demands of economic development for mineral resources, non-coal mines have undergone accelerated large-scale mining. This gradually exhausts shallow mineral resources. Therefore, underground deep mining has become an inevitable choice to obtain resources. In a deep mining environment, accidents and disasters such as ground pressure, rockburst, water inrush, poisoning, and fire hazards often occur due to factors such as high ground pressure stress, high temperature and humidity, high hydraulic pressure, poor air quality, long power supply circuits. In recent 30 years, domestic underground non-coal mines have undergone increasingly deepening and rapid mining. However, safety production technologies fail to keep pace, causing many safety problems and even major accidents such as ground pressure disasters. This continuously increases production costs, and even pays a heavy cost of life. The ground pressure disasters in deep mining of the underground non-coal mines have become a main bottleneck of mining of mineral resources. Therefore, a problem to be solved urgently for sustainable economic development is how to reduce and even avoid casualties and tremendous economic losses caused by the ground pressure disasters of the non-coal mines. To reduce and even avoid casualties and economic losses caused by ground pressure disasters of mines, in addition to improving mining technologies, a safety monitoring and early-warning technology can be used to predict an accident. The technology performs real-time monitoring to master a law and a location of a ground pressure activity in a non-coal mine, and analyzes and predicts a future development trend of ground pressure, to provide a scientific basis for formulation of ground pressure prevention measures and treatment schemes. This can effectively reduce hazards caused by the ground pressure. For a long time, wired underground safety monitoring and radio frequency identification (RFID)-based underground safety monitoring are used for the underground non-coal mines, and safety supervision technologies lag behind. In some underground non-coal mines, safety parameters are still detected through regular visual inspection or by using a traditional monitoring instrument on site, causing heavy workload. This results in a large monitoring error, a dead zone, and non-real-time and unreliable monitoring data due to many factors such as on-site conditions, time, and staff. Discrete data is not conducive to continuous monitoring and analysis. In the deep mining environment, use of a current wired online safety monitoring system for underground mines will cause many problems such as too long cables, high I costs, many connectors and interfaces, poor reliability, and inconvenient network adjustment, layout, and expansion. All these are main factors of affecting improvement of a safety monitoring technology for underground continuous deep mining in the non-coal mines. SUMMARY An objective of the present disclosure is to provide a wireless sensor network-based intelligent safety monitoring system for an underground non-coal mine, to resolve the foregoing problems. The present disclosure provides a wireless sensor network-based intelligent safety monitoring system for an underground non-coal mine. The system includes a plurality of wireless sensor subnetworks and a plurality of sensors that are disposed in a mine, and a central switch, a data processing server, and a comprehensive supervision platform that are disposed on the ground. The wireless sensor subnetwork includes a wireless sensor node, a convergence gateway node, a reference node, and a mobile node. The reference node can update a corresponding parameter in a data packet of the reference node by using a periodic broadcast signal of another adjacent reference node. The wireless sensor node is connected to the sensor to perform signal conversion and transmission. The mobile node is disposed on a worker or a mobile device in the mine, and is located through calculation, sorting, and comparison based on the data packet of the reference node, a recorded identifier (ID) of an adjacent mobile node, and information in a database. The convergence gateway node is mounted to the central switch by using a wired network, to receive wireless data sent by the reference node, the mobile node, and the wireless sensor node, convert the received wireless data into wired data, and send the wired data to the central switch. The central switch converts the data sent by the convergence gateway node into wired data, transmits, by using the wired network, the wired data to the data processing server for processing, and then uploads processed data to the comprehensive supervision platform. Further, the wired network may be a controller area network (CAN)-based wired network or an Ethernet. Further, the reference node includes a microprocessor module, a storage module, a wireless transceiver module, and a power module. Further, the mobile node includes a microprocessor module, a storage module, a wireless transceiver module, and a power module. Further, the sensors are configured to detect an environment status in the mine in real time, and include a ground pressure microseism sensor, a temperature and humidity sensor, a negative pressure sensor, a wind speed sensor, a power-off and feed sensor, a carbon monoxide sensor, and a pressure and displacement sensor. The present disclosure has the following beneficial effects. The wireless sensor network-based intelligent safety monitoring system for an underground non-coal mine in the present disclosure can collect safety-related environment data such as a ground pressure microseism and location information of workers in the mine in real time, analyze the environment data, and locate a danger, thereby effectively preventing a safety accident. In addition, the system can accurately locate the workers after an accident to provide effective support for search and rescue, thereby greatly improving safety of operations in the mine.
