Problems solved by technology

[0012] With the gradual popularization and application of wireless technology in the coal mine safety monitoring network, the problem of wireless transformation and networking of existing equipment is becoming more and more difficult. Due to the different monitoring objects and usage scenarios, there are too many products that need to be transformed. If it is transformed, the total number of hardware products of the coal mine safety monitoring system will increase by 50%, and the workload and investment of the entire wireless transformation will be too large
