Embodiment 1

[0042] Such as figure 1 As shown, the coal mine dynamic disaster detection system includes a monitoring center and a front-end sensing device arranged underground. The monitoring center obtains data collected by the front-end sensing device through a mobile terminal; the mobile terminal communicates with the host of the monitoring center through a USB interface protocol The equipment is connected to realize data transmission; the mobile terminal transmits electromagnetic waves to the front-end sensing device through the QI / WPC protocol; the mobile terminal performs wireless data transmission with the front-end sensing device through the TransferJet protocol;

[0043] Such as figure 2 As shown, the mobile terminal includes a terminal controller, a DC power supply, a wireless charging and transmitting circuit, a wireless communication receiving module, and a charging switch circuit; the DC power supply and the wireless charging and transmitting circuit perform power transmission thr...

Embodiment 2

[0064] This embodiment is different from embodiment 1 in that the front-end sensing device further includes a temperature sensor for detecting the front-end sensing device, and the signal output end of the temperature sensor is connected to the signal input end of the front-end controller.

[0065] The difference between the data collection method of the wireless monitoring system for underground operations in this specific embodiment and the data collection method in specific embodiment 1 is that the wireless charging mode in step 5 is intermittent charging, and every charging T time Then switch to the wireless data collection mode, and proceed as follows:

[0066] Step 101: Close the charging switch circuit, and the mobile terminal switches to the wireless charging working mode. After charging for T time, disconnect the charging switch circuit to make the mobile terminal work in the wireless data collection working mode;

[0067] Step 102: the mobile terminal establishes a data con...

Abstract

The invention relates to the technical field of the wireless charging and the data wireless communication, and especially relates to a mine dynamic disaster detection system, a data collection methodand a wireless charging method thereof. The system comprises a monitoring center and a plurality of front-end sensing devices arranged underground; the monitoring center acquires data collected by thefront-end sensing devices through a mobile terminal; the power transmission is performed between a DC power supply of the mobile terminal and a wireless charging-transmitting circuit through a charging switch circuit; the charging switch circuit produces a corresponding switching value signal when being switched on or off and sends the corresponding switching value signal to a terminal controller; a wireless communication receiving module is connected with a signal input end of the terminal controller; the terminal controller controls a working state of the wireless communication receiving module according to the switching value signal; each front-end sensing device comprises a sensor and a front-end controller, and a signal output end of the front-end controller is connected with a wireless communication sending module. The layout of a cable is avoided, the construction cost is reduced, and the security of the data collection is improved.

Description

Technical field [0001] The invention relates to the technical field of wireless charging and data wireless communication, in particular to a coal mine dynamic disaster detection system and its data collection method and wireless charging method. Background technique [0002] As our country's basic energy and important raw material, how to produce coal safely and efficiently has been widely concerned by the people. The harsh and complex working environment of the mine and long-term overloaded mining have caused frequent equipment failures. Therefore, the equipment maintenance system is very important in the modern production of coal enterprises. The equipment status monitoring system extracts effective information and parameters from the equipment operating status signals, and provides raw data for the equipment maintenance system, so that maintenance personnel can understand the operating status of the equipment at any time, improve equipment reliability and utilization, and avoi...
