10, relay can be selected the JRC-21F type for use.
Principle of work of the present invention as shown in Figure 1 is as follows: sensor 1 is by supply lines 1.2,1.3 power supply, and gas signal is passed to signal processor 2 by the components and parts of sensor internal with the electric signal signal wire 1.1,1.4 of transmitting scriptures.The inside of signal processor 2 is divided into the two-way circuit output signal: the one road is to lead to alarm the 8,2.1, the 2.2nd, the supply line of alarm, the 2.3rd, alerting signal circuit; Another road be by 2.4,2.5 link testers to solenoid valve controller 5, power supply is powered and to relay 10 this relay is connected, and makes solenoid valve controller 5 obtain working currents.When relay 10 was received the control signal electric current, relay 4 was promptly worked, thereby made solenoid valve 9 outages, and solenoid discharges magnetic force, makes solenoid valve be in normally off, at this moment the source of the gas of closed electromagnetic valve pipeline.
In the embodiment of the invention: signal processor 2 is integrated circuit blocks, is to use the TC1410 type, has wherein increased circuit annex 3, and this circuit annex 3 is the detecting circuits with the diode detection, in the signal input ic of detection.
That the invention will be further described is as follows below in conjunction with wiring diagram: as shown in Figure 1 and Figure 2, circuit is compositions such as integrated packages such as gas sensor 1, signal processor 2, solenoid control 9, alarm 8 and triode, diode, accurate stabilivolt, resistance, electric capacity adjustable resistance, relay.
As shown in Figure 2, the course of work of this circuit is:
Send signal by gas sensor by its inner original paper, but signal reaches in the integrated circuit block after by diode D2 detection.Signal is analyzed by signal processor integrated package inside, and output is amplified by triode GB5 after treatment, the be utmost point of GB5 is connected, at this moment made relay 4 work, cut off the rear portion circuit by relay, but report to the police when cutting off the rear portion circuit, circuit will go out realize voice and siren; But make the coil blackout of solenoid valve when reporting to the police, solenoid valve can't be worked, the sealed valve of solenoid valve will be pushed closed condition to by the seal head that it is inner, and source of the gas is tightly sealed, and obtains safer effect.
Among the figure, D1 is the operating voltage that a standard is arranged to signal processor integrated circuit (IC) 2.After solenoid control is closed in the circuit execution, solenoid valve 9 is in normally off, make circuit working, must control starting switch, make the connector lug of starting switch by the base stage of the common point of the R7 in the starting circuit, C1 and diode BG2 with manual or remote controller, behind the circuit start, J2 work in the circuit makes the coil working in the solenoid valve, at this moment, solenoid valve will produce certain magnetic force with valve open, and source of the gas is passed through smoothly.Circuit after starting leaks to gas when sensor and exceeds standard, and it can close solenoid valve (also can artificially cut off the power supply and close solenoid valve) automatically, and above process is gone round and begun again.Behind the closed electromagnetic valve, alarm is monitoring environment safety still.
Among Fig. 1, Fig. 2, for the power supply of powering in the circuit can be the external power supply 7 that dry battery power or alternating current-direct current voltage stabilizing are exchanged.When being external power supply, the external power supply input voltage is 220V.Circuit voltage is 1.5-36V.The operating voltage of relay 4 is 1.5-12V, and the operating voltage of signal processor 2 is 1.5-12V, and the operating voltage of solenoid valve 9 is 1.5-9V.
In the more particular embodiment, the operating voltage of sensor 1 is 1.5-6V, and the stabilized voltage supply output voltage is 1.5V, 6V and 12V, and the operating voltage of signal processor 2 and relay 4,10 all can be 12V, and the operating voltage of solenoid valve 9 is 1.5V.
The embodiment of sensor 1 of the present invention has liquefied petroleum device sensor, generally installs one, preferably installs two, and two advantage is that when an inefficacy, another can replace automatically.
Also have in the preferred version of the present invention: except that external power supply, remaining part all is contained in the housing; When the large-scale gas apparatus of remote management or enterprise used, solenoid valve can be parts independently, and all the other are contained in the housing.These different structural advantages are, are fit to the different user needs, and structure is tightly beaten, easy to use and management.
