Abstract
The utility model discloses an intelligent natural gas alarm, comprising an acquisition module detecting gas leakage concentration, a solenoid valve controlling on-off of gas pipelines, an alarm sending out alarm signals, and a microprocessor respectively connected with the above devices and controlling operation of the devices. The microprocessor is also connected with a remote communication module. A dangerous case long-distance notification function is added on the basis of the prior art. When the natural gas leaks out, the system calls owners and real estate departments in first time, or informs heads of household through GPRS or GSM short messages, and meanwhile sends messages to mobile phones of the real estate departments, thereby preventing circumstances that users are not at home (or have not heard the alarm sound), so that potential safety hazard is eliminated in time.
Description
Technical field
The utility model relates to the fire protection warning field, is specifically related to a kind of natural gas warning device that multiple type of alarm can be provided at the closing fault gas pipeline simultaneously.
Background technology
the natural gas reports to the police machine of the prior art is after around detecting, rock gas being arranged, send again a kind of device of alarm signal, specifically detect airborne concentration of natural gas by the respective smell concentration detector, after exceeding standard, rock gas can send corresponding sound and light alarm, technology is when improving this type of alarm now, mainly also to improve the sensitivity that gas is detected, or increase can be responded to rock gas simultaneously, the inductor of coal gas and other harmful gas, or the solenoid valve on corresponding gas supply pipe is combined, not only send warning but also cut off simultaneously gas circuit when measuring corresponding gas concentration and exceed standard.
But aforesaid way can not prevent solenoid valve and leak the problem of a class, like this, still exists even sent warning message hidden danger, and as on-the-spot unmanned, hidden danger can not in time be got rid of.
The utility model content
For solving the problem of natural gas warning device shortage remote alarms in prior art, it is a kind of simultaneously to scene take measures also in time to notify by remote mode litigant's natural gas warning device that the utility model provides, concrete scheme is as follows: a kind of intelligent the natural gas reports to the police machine, comprise the acquisition module that detects Leakage Gas concentration, control the solenoid valve of gas piping break-make, the microprocessor that sends the warning device of alerting signal and be connected and control respectively the said equipment work with the said equipment, described microprocessor also is connected with remote communication module.
For realizing telecommunication: described remote communication module is the GPRS wireless module, and the model of described GPRS wireless module is SIM300C.
For improving processing speed: described microprocessor is the STC15F2K60S2 single-chip microcomputer.
The utility model increases dangerous situation " long-range informing " function on the prior art basis, system gives by GPRS within the very first time and informs householder, property section mobile phone while photos and sending messages when having rock gas to omit, prevent user's phenomenon of (or not hearing chimes of doom) of staying out, thereby eliminate safe hidden trouble timely.

Embodiment
As shown in Figure 1, intelligent the natural gas reports to the police machine of the present utility model, comprise the acquisition module 2 that detects Leakage Gas concentration, control the solenoid valve 3 of gas piping break-make, the microprocessor 1 that sends the warning device 4 of alerting signal and be connected and control respectively the said equipment work with the said equipment, described microprocessor 1 also is connected with remote communication module 5.
This programme is when work, microprocessor 1 receives the signal of acquisition module 2, when signal belongs to default alerting signal, can send cut-off signals to solenoid valve 3, simultaneously send enabling signal to warning device 4, warning device 4 can be corresponding hummer or the acoustic-optic alarm that is attended by luminaire, warning device 4 sends warning near indoor or people, when stating work in realization, microprocessor 1 is according to the contact number that is reserved in storer, send SMS notification by remote communication module 5 to it, realize synchronous remote alarming function.Concrete reserved call can be that particular user can be also property one class monitoring management department.
As shown in Figure 2, microprocessor 1 in the utility model is the master controller of system, microprocessor 1 adopts the STC15F2K60S2 single-chip microcomputer, the STC15F2K60S2 single-chip microcomputer is provided with the EEPROM that can write, read, wipe, and the information of its preservation do not lose under powering-off state yet, and the contact number of reservation can arrange 1-5 and can change at any time the input reserved number.Can also realize sending alarming short messages or only to the number transmission of appointment, facilitating different users to set as the case may be to all numbers simultaneously on arranging.The STC15F2K60S2 single-chip microcomputer has high speed, low-power consumption, superpower jamproof characteristics, CPU adopts STC-Y5 hypervelocity kernel, the fully compatible tradition 8051 of instruction code, but the fast 8-12 of speed doubly, inside is integrated with high precision R/C clock and highly reliable reset circuit, can thoroughly save outside expensive crystal oscillator and reset circuit.Be provided with 3 road PCA in the STC15F2K60S2 single-chip microcomputer, can carry out 8 tunnel 10 high-speed a/d conversions, the large capacity SRAM of built-in 2K byte, external 2 groups of high-speed asynchronous serial ports UART1/UART2,1 group of high-speed synchronous serial ports SPI satisfies expansion demand fully.GPRS module in the utility model is wireless sending module, and concrete GPRS model is selected the SIM300C of SIMCOM company, and the SIM300C module interface is simple, good stability, embedded ICP/IP protocol stack, and is easy to use.
As shown in Figure 3, be provided with gas sensor in acquisition module 2 of the present utility model, gas sensor adopts heater-type SnO2 gas sensor, after adopting this structure, its measurement utmost point separates with heater strip, heater strip does not contact with gas sensor, has avoided interacting between the loop, has improved stability.When inflammable gas not detected, the A of gas sensor, B two ends are high-impedance state, the center head of potentiometer RP is low level, after gas sensor detects inflammable gas, resistance value between its A, B end diminishes, the output terminal that makes potentiometer RP is high level, and high level signal outputs to microprocessor 1 by logic judging circuit, and microprocessor 1 is carried out corresponding running.Variation from high to low will appear in the output terminal of potentiometer RP when combustion gas occuring omit, and this signal is as to the center head taking-up by potentiometer RP of the interrupt request singal of microprocessor.
