Problems solved by technology

[0003] The purpose of the present invention is to overcome the defects of traditional underground data collection system wired network construction difficulty, high system cost, difficult maintenance, inability to check the working condition of the alarm at any time, and inability to provide accurate search and rescue information, or to adopt the radio wave method At the same time, the radio waves in the middle frequency and high frequency bands are affected by the complex electromagnetic environment, and the attenuation of the radio waves is very large during the transmission process. A safety instrument that is carried by every miner is provided. , humidity, gas and other sensors, so that the command center on the well or outside the tunnel can keep abreast of the surrounding environment information of the workers in the mine or in the tunnel, and realize a device for on-site voice and video communication

Embodiment 1

[0029] When using this miner's portable safety instrument, the communication distance between the two parties is relatively long or when the direct communication is not possible, a wireless signal repeater 7 needs to be added midway, and a battery 6 is used to supply power to ensure the effective transmission of the signals of both parties. The selected modules are;

[0030] Single-chip microcomputer 1 adopts the MSP430F149 single-chip microcomputer of Texas Instruments (TI), the working current of which is only 0.8μA under the dormant condition, even if the working current is only 280μA under the condition of 2.2V and 1MHz, it can well meet the low requirements of the device. Power consumption requirements; 16-bit RSIC structure, the execution time of the instruction only needs 150ns, and there is also an efficient look-up table processing method, which has a high processing speed, and the computing power can reach 1MIPS under the 8MHz crystal; there are two 16-bit on-chip Th...

Embodiment 2

[0045] When the distance between the communicating parties is within 100 meters, there is no need to use a relay to realize data transmission, that is, it is not necessary to use the battery 6 and the wireless signal repeater 7, which can save system cost and reduce system power consumption. Other parts of this embodiment are the same as in Embodiment 1.

Abstract

The invention relates to a portable safety instrument for miners and belongs to the field of information and automation. The instrument comprises a microprocessor, a storage circuit, a data acquisition circuit, a speech coding circuit, a wireless radio frequency module, a battery, a wireless signal repeater, earphones, a wireless video transmission module, a power supply module, a warning circuit, a serial port circuit, a keyboard circuit and a display module. The portable safety instrument is a device which can be used for learning about information on surrounding environment of a miner and realizing voice and video communication with a working field. The system of the device adopts the wireless radio frequency module to realize data transmission in a repeater mode. The safety instrument provides a good solution to problems of monitoring people, early warning and rescuing in mines, tunnels and other isolated environments. The safety instrument has the characteristics of low cost, low consumption, high performance, portability and so on, and can be used as a common portable safety instrument for miners.

Description

technical field [0001] The invention belongs to the field of information and automation, and in particular relates to a portable safety instrument for miners. Background technique [0002] Mine and tunnels are high-risk operating environments. Therefore, remote data monitoring of these environments will help the command center above the mine or outside the tunnel to better understand the environmental safety conditions in the mine or in the tunnel, and cooperate with the on-site personnel in the mine or in the tunnel to take measures. , Eliminate potential safety hazards. When a safety accident has taken place, if the situation in the well or in the tunnel can be grasped on the well or outside the tunnel, it will be helpful for them to take rescue measures. Traditional underground data acquisition systems generally use wired networking, which can effectively avoid signal interference problems. However, due to the complex underground environment, this method has the disadvan...
