Abstract
The utility model relates to mining safety monitoring system equipment, in particular to a high-efficiency energy-saving automatic mine gas emission system, which comprises a CPU control module. A detection system input portion of the CPU control module is connected with a gas sensor positioned on an excavation working surface, an instruction output portion of the CPU control module is connected with a direct-current permanent magnetic motor via a variable-frequency speed controller, the direct-current permanent magnetic motor arranged in a ventilation tunnel is used for controlling a fan to operate, and the CPU control module is further connected with a ground control module via an RS485 communication interface. The system can achieve the purpose of quantitative ventilation according to needs by processing real-time value of the gas sensor via the CPU control module and automatically regulating rotation speed of a local ventilator accordingly, not only realizes safe emission of gas concentration with maximum efficiency, but also simultaneously realizes automatic monitoring of wind volume and gas concentration, and provides running data for ground monitoring equipment.
Description
Technical field
The utility model relates to coal mine safety monitoring system equipment, specifically is that a kind of coal mine gas is efficient, energy-saving automatic discharge system.
Background technology
The mine underground safety monitoring is the important step of Safety of Coal Mine Production, and gas is disaster source main under the coal mine, and the gas density of getting working face reduces to below 1% its concentration as not detecting in time safely and discharge, and will cause great production accident.The past people adopt the method firedamp drainage of artificial perusal and artificial gas surveying interaction usually, and accuracy is low, security reliability is poor.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of coal mine gas simple in structure, that safety good, energy consumption is low efficient, energy-saving automatic discharge system
Efficient, the energy-conservation exhaust system of coal mine gas of the present utility model includes a CPU control module, the detection signal importation of CPU control module is connected with the firedamp sensor that is positioned at the getting working face place, the instruction output of CPU control module is connected by the direct current permanent magnet motor that is used for controlling the blower fan running in variable-frequency governor and the airway, and the CPU control module is also passed through the RS485 communication interface and is connected with the Ground Control module.
The utility model is handled the firedamp sensor instantaneous value by the CPU control module, and regulate the rotating speed of booster on this basis automatically, thereby can reach the purpose of quantitatively ventilating as required, both realized safety dumping to the gas density maximal efficiency, also realize monitoring air quantity and gas density automatically simultaneously, for surface-monitoring equipment provides service data.
Description of drawings
Fig. 1 is the system architecture schematic diagram of the utility model embodiment.
The specific embodiment
As shown in the figure, system includes a CPU control module 1, the detection signal importation of CPU control module is connected with the firedamp sensor 2 that is positioned at the getting working face place, the instruction output of CPU control module is connected by the direct current permanent magnet motor 3 that is used for controlling the blower fan running in variable-frequency governor and the airway, the CPU control module also is connected with the Ground Control module by the RS485 communication interface, is used for transmitting earthward rotation speed of fan and gas density information.
In the actual use of the utility model embodiment: when on-the-spot gas density exceeds standard, enter the firedamp drainage state automatically, real-time safety dumping to the gas density maximal efficiency; When on-the-spot gas density does not exceed standard, regulate air quantity automatically, realize energy-saving ventilating air, economize on electricity is more than 45%; The function such as rotating switching, manual governing control of wind, electricity, gas shutting, booster can be set; Be applicable to frequency or electric current firedamp sensor, compatible fully with underground detection system.
