Description

A New Type of Underground Safety Warning Device

technical field

The utility model relates to a novel underground safety warning device.

Background technique

Warning signs in the traditional sense can only serve as a reminder visually, but cannot actively remind workers and cannot highlight the particularity of the warning location. The underground environment is harsh, the lighting effect is poor, and the paint is easy to fall off by itself, causing the handwriting to be blurred and difficult to identify. The existing warning signs have problems such as poor recognition, blurred handwriting, and difficult to find in actual use underground. The work of blasting and other work is still done by manpower. Due to the intensity and pressure of underground work, workers are prone to slack, resulting in potential safety hazards.

Contents of the invention

The utility model is proposed in order to solve the above problems and is a novel warning sign for mining with functions such as active reminder and long-distance remote control.

A new type of underground safety warning device includes a microprocessor, a sound alarm circuit, a display circuit, a display screen, a light control circuit, a warning light, an infrared signal sensor, a signal amplification circuit, an ultrasonic signal receiving circuit, a voltage stabilizing circuit, a power supply, and a switch , ultrasonic remote control, speaker. The infrared signal sensor is connected with the signal amplification circuit to the microprocessor. The ultrasonic signal receiving circuit, the sound alarm circuit, the display circuit and the lighting control circuit are connected with the microprocessor. The microprocessor is the bottleneck and core of the entire device, and it is the guarantee for the stable operation of the entire system. The remote control is used to control the opening and closing of the warning signs, and can control multiple warning signs at the same time. The warning signs can be placed in different positions to expand the warning range. The information is transmitted between the remote control and the warning sign through ultrasonic waves, which is not affected by the corners and bends of the roadway.

Detailed ways

When a warning area needs to be set up due to work, workers can control the opening of the warning sign at the corresponding position through the remote control.

The remote controller sends information through ultrasonic waves, and the ultrasonic signals are received by the ultrasonic signal receiving circuits placed on the warning signs at different positions, and then the ultrasonic digital signals are transmitted to the microprocessor. Under the control of the microprocessor, the sound alarm circuit, the display circuit, the light control circuit and the infrared signal sensor start to work. The sound alarm circuit sends out an alarm sound to remind workers to evacuate, the display circuit controls the screen to display warning slogans, the light control circuit controls the warning lights to flash, and the infrared signal sensor starts to work.

When a worker strays into the forbidden area, the infrared signal sensor transmits the signal to the microprocessor through the signal amplifier, and the microprocessor sends an alarm signal to the sound alarm circuit, display circuit, and light control circuit. Enter and suspend related work.

After the work is over, the ultrasonic remote control mine warning sign can be turned off through the ultrasonic remote control. The warning sign receives the signal from the remote control, the speaker plays the sound of the alarm, the warning light is turned off, and the screen is turned off, so as to proceed to the next work.
