Description
Technical field
The present invention relates to a kind of mine anti-explosion early-warning lamp controller.
Background technology
Along with the increase of the pit mining degree of depth and the extension of underworkings, the threaten degree of various disasters is all increasing, and shows that gas emission is increasing, and mine pressure increases, and hazard management is complicacy etc. more.Be equipped on the safety in production monitoring and controlling system in the mine at present; Generally be that main location is provided with sensors of various types collection associated safety data message in the down-hole, through the downhole data transmission circuit down-hole associated safety data message be sent to the ground early-warning management system in real time then.At present, day mineral adopts PLC controller or single-chip microcomputer mostly with the monitoring and warning management system, and control strategy is complicated, and cost is too high, and energy consumption is also high, and the scope of application is less.
Summary of the invention
In order to overcome the above-mentioned defective that prior art exists, the present invention provides a kind of cost of production low, mine anti-explosion early-warning lamp controller applied widely.
Technical scheme of the present invention is: it comprises control circuit, and said control circuit one end is connected with the particle sensor output port, and the control circuit other end is connected with amplifying circuit one end, and the amplifying circuit other end is connected with main circuit, and main circuit is provided with early-warning lamp.
Further, said control circuit is provided with diode D, and control circuit is connected with particle sensor through diode D anode.
Further, also be provided with antioverloading resistance R 1 on the said control circuit, antioverloading resistance R 1 one ends are connected with diode D negative electrode, and the other end is connected with amplifying circuit.
Further, said amplifying circuit is provided with triode B1, and amplifying circuit is connected with control circuit through triode B1 base stage.
Further, also be provided with antioverloading resistance R 2 on the said amplifying circuit, antioverloading resistance R 2 is connected with the emitter stage of triode B1.
Further, said main circuit is provided with triode B2, and main circuit is connected with amplifying circuit through triode B2 base stage, and the colelctor electrode of triode B2 is connected with early-warning lamp one end.
Further, also be provided with antioverloading resistance R 3 on the said main circuit, antioverloading resistance R 3 is connected with the emitter stage of triode B2.
Operating principle: when particle sensor monitors under the mine after dangerous blast particle concentration surpasses setting value; Particle sensor sends the high level signal of representing early warning to control circuit, and high level signal gets into the diode in the control circuit, its electric current be allowed to through; Electric current gets into the triode B1 of amplifying circuit; Amplifying circuit is started working, and the electric current after triode B1 amplifies flows into main circuit triode B2, makes to be in the main circuit formation path that opens circuit originally; Early-warning lamp begins luminous warning, reaches the early warning effect.
When the blast particle concentration is reduced to setting value when following, particle sensor sends the low level of expression safety, and at this moment amplifying circuit quits work, and main circuit is in off state again, and early-warning lamp goes out, and reaches to remove the early warning effect.
The present invention is simple in structure, compact, and cost of production is low, and is easy to use, and energy consumption is low, applied widely, can fully guarantee the accuracy of early warning signal.

Fig. 1 is the structured flowchart of the embodiment of the invention;
Fig. 2 is a kind of particular circuit configurations figure of the embodiment of the invention;
Fig. 3 is a control strategy sketch map of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further.
With reference to Fig. 1,2, present embodiment comprises control circuit 2, and control circuit 2 one ends are connected with particle sensor 1 output port, and control circuit 2 other ends are connected with amplifying circuit 3 one ends, and amplifying circuit 3 other ends are connected with main circuit 4, and main circuit is provided with early-warning lamp LED.Control circuit 2 is provided with diode D, and control circuit 2 is connected with particle sensor 1 through diode D anode.Also be provided with antioverloading resistance R 1 on the control circuit 2, antioverloading resistance R 1 one ends are connected with diode D negative electrode, and the other end is connected with the triode B1 base stage of amplifying circuit 3.Also be provided with antioverloading resistance R 2 on the amplifying circuit 3; Antioverloading resistance R 2 is connected with the emitter stage of triode B1; Main circuit 4 is provided with triode B2; Main circuit 4 is connected with the colelctor electrode of the triode B1 of amplifying circuit through triode B2 base stage, and the colelctor electrode of triode B2 is connected with early-warning lamp LED one end.Also be provided with antioverloading resistance R 3 on the main circuit 4, antioverloading resistance R 3 is connected with the emitter stage of triode B2.
Operating principle: with reference to Fig. 3, (1) when particle sensor 1 monitors under the mine when dangerous blast particle concentration is lower than setting value, particle sensor 1 sends to control circuit 2 and represent safe low level signal; Low level signal gets into the diode D in the control circuit 2; Owing to be low level, diode D does not allow electric current to pass through, and amplifying circuit 3 is with main circuit 4 and opens circuit; Early-warning lamp LED does not work, the expression security situation;
(2) dangerous blast particle concentration is above after the setting value under the mine when particle sensor 1 monitors, and particle sensor 1 sends the high level signal of representing early warning to control circuit 2, and high level signal gets into the diode D in the control circuit 2; Owing to be high level, diode D allows its electric current to pass through, and electric current gets into the base stage of amplifying circuit triode B1; At this moment amplifying circuit 3 transfers path to; Electric current makes to be in the main circuit 4 formation paths that open circuit originally through the base stage of triode B1 inflow main circuit 4 triode B2, and early-warning lamp LED begins luminous; Reach the early warning effect, the expression dangerous situation;
When particle sensor 1 continued to monitor under the mine dangerous blast particle concentration and surpasses setting value, early-warning lamp LED kept lamp bright always, reaches the early warning effect, and expression continues dangerous situation;
(3) be reduced to setting value when following when the blast particle concentration, particle sensor 1 sends the low level of expression safety, and at this moment amplifying circuit 3 quits work, and main circuit 4 is in again and opens circuit, and early-warning lamp LED goes out, and reaches to remove the early warning effect, and expression pulls through situation.
