Embodiment 1

[0033] Such as Figure 7As shown, a wireless communication system based on a miner's hat lighting lamp includes a miner's hat 4 and an optical wireless transmitter 1, a receiver 2, a control unit, an electric wire 5 and a rechargeable battery power supply 6 arranged on the miner's hat 4 . The control unit realizes the control of the transmitting end and the receiving end through the program, and the transmitting end control code and the receiving end control code belong to two independent threads to facilitate the system to carry out full-duplex communication.

[0034] The specific implementation is as follows:

[0035] 1. System control

[0036] Such as figure 1 As shown, the control unit is connected to the transmitter 1 and the receiver 2 to form a transceiver system. The control unit includes a single-chip microcomputer and a clock module, a keyboard and an indicator light module on the periphery of the single-chip microcomputer.

[0037] as attached figure 2 As show...

Abstract

The invention discloses a wireless talkback communication system based on an LED (Light Emitting Diode) miner cap illuminating lamp. The communication system comprises a miner cap body, a light wireless transmitting end, a receiving end, a control unit, an LED miner cap and a charging battery, wherein the light wireless transmitting end, the receiving end, the control unit and the LED miner cap are arranged on the cap body; the control unit is connected with the transmitting end and the receiving end to constitute a receiving-transmitting system; the control unit comprises a singlechip and a clock module and an indicating lamp module which are arranged at the periphery of the singlechip; and the singlechip is used for controlling the receiving end and the transmitting end, finishing processing a transmitting signal and a receiving signal, performing AGC (Automatic Gain Control) amplification and A/D (Analog to Digital) conversion on an audio signal acquired from the transmitting end, encoding a digital signal, loading the encoded signal on an LED modulation illuminating circuit, controlling the receiving end to convert a received light signal into an electric signal and regenerate and reduce the electric signal into a digital signal, reducing the digital signal output by the receiving end into a voice signal by performing Manchester decoding and D/A (Digital to Analog) conversion, and transmitting the voice signal to a loudspeaker of the receiving end.

Description

technical field [0001] The invention belongs to the field of underground short-distance lighting communication, and in particular relates to a system for realizing wireless voice communication through a miner's hat lighting lamp. Background technique [0002] With the rapid development of my country's economy, people's demand for energy is increasing day by day. At the same time, more and more attention has been paid to coal mine safety production. Traditional underground lighting equipment (incandescent lamps, fluorescent lamps, high-pressure sodium lamps, etc.) are prone to sparks due to power problems, which can easily cause gas explosion and combustion. The most prominent advantage of white LED, the new fourth-generation light source known as lighting technology in the 21st century, is low power consumption, which can effectively reduce electric sparks. Therefore, white LEDs with the advantages of safety, high efficiency, green environmental protection, low heat genera...
