The device comprises a signal acquisition module, a main control module, an electronic valve driving module, an acousto-optic alarm module and a wireless communication module, and the device is characterized in that the main control module is respectively connected with the signal acquisition module, the electronic valve driving module, the acousto-optic alarm module and the wireless communication module. The signal acquisition module is used for monitoring gas. When the practical gas concentration exceeds the set value, the signal acquisition module is used for inputting high level signals to the main control module, the main control module is used for receiving signals to work, driving the acousto-optic alarm module composed of a light emitting diode, a buzzer and peripheral devices to work, and controlling the electronic valve driving module to cut a solenoid valve and prevent continuing output of gas. The wireless communication module is used for dialing a preset user mobile phone number, and a user will receive an alarm short message from the wireless communication module.

Description

Wireless gas alarm device

Technical field

The utility model relates to a kind of gas alarm device, especially wireless gas alarm device.

Background technology

The progressively enhancing with security precautions of improving constantly along with the national life level, people begin more and more to be concerned about the living environment of oneself, not only require hommization and comfortableization of domestic environment, and intelligent and safe also had higher requirement, also arise at the historic moment in corresponding research and development field, new technology, new product emerge in an endless stream.

Summary of the invention

In view of above these situations, the utility model provides a kind of wireless gas alarm device.Introduce advanced GSM mechanics of communication, utilized gsm wireless communication network, intelligent monitor and user mobile phone terminal to make up the monitoring and alarming system of a cover perfect in shape and function.This system can at user's durante absentia, carry out Real Time Monitoring to the safe handling of whole combustion gas.

The utility model provides a kind of wireless gas alarm device, comprise signal acquisition module, main control module, electrovalve driver module, sound and light alarm module, wireless communication module, it is characterized in that: main control module is connected with signal acquisition module, electrovalve driver module, sound and light alarm module, wireless communication module respectively.Signal acquisition module is responsible for the monitoring of combustion gas.When actual gas concentration surpasses setting value, signal acquisition module is input to high level signal in the main control module, main control module receives signal and starts working, drive the sound and light alarm module work that light emitting diode, hummer and peripheral components consist of, control simultaneously the electrovalve driver module, cut off solenoid valve, stop the continuation output of combustion gas.Wireless communication module can be put through the subscriber phone number that prestores, and the user will receive one from the alarming short message of wireless communication module.

The beneficial effects of the utility model are that warning device has a style of one's own, and is easy for installation, reports to the police rapidly, simple in structure, with low cost, has higher practical value.

Embodiment

In Fig. 1, in Fig. 1, the utility model provides a kind of wireless gas alarm device, comprise signal acquisition module 1, main control module 2, electrovalve driver module 3, sound and light alarm module 4, wireless communication module 5, it is characterized in that: main control module 2 is connected with signal acquisition module 1, electrovalve driver module 3, sound and light alarm module 4, wireless communication module 5 respectively.Signal acquisition module 1 is responsible for the monitoring of combustion gas, when actual gas concentration surpasses setting value, signal acquisition module 1 is input to high level signal in the main control module 2, main control module 2 receives signal and starts working, drive sound and light alarm module 4 work that light emitting diode, hummer and peripheral components consist of, control simultaneously electrovalve driver module 3, cut off solenoid valve, stop the continuation output of combustion gas.Wireless communication module 5 can be put through the subscriber phone number that prestores, and the user will receive one from the alarming short message of wireless communication module.

Signal acquisition module 1 is comprised of sensor, amplifier LM358 etc.Sensor is used for gathering outside gas concentration, and collection capacity and the preset value of setting by hardware circuit are compared, and when collection capacity was higher than preset value, discharge circuit output signal " 1 " drove main control module 2 work.Main control module 2 is comprised of AT89S51 single-chip microcomputer and power management, crystal oscillator module etc.AT89S51 is a kind of low-power consumption, high-performance CMOS 8 8-digit microcontrollers, the control requirement that 128 byte ram in slice of its inside and 4KBFlash storer satisfy system.The P1 port connects the signal acquisition module 1 that is comprised of gas security and discharge circuit, and the P0 port connects sound and light alarm module 4 and electrovalve driver module 3, in sound and light alarm module 4 parts mainly by amplifier, light emitting diode, protective resistance, and ring composition.Electrovalve driver module 3 is comprised of electrochemical capacitor (4.7U/25V), amplifier (9013), relay and solenoid valve.When the actual gas concentration that collects during greater than default value, the P0.1 mouth outbox implementation method of 89S51 chip.In design process of hardware, introduce effective energy-saving design thought, the high level signal of using under the normal condition, by amplifying circuit the control signal amplification is transferred to relay, be in sleep state by the alarm relay device, when having anomalous event to occur, just be waken up, can greatly reduce like this high level signal of emission to solenoid valve, the solenoid in the solenoid valve generates an electromagnetic field in switch pass power consumption, extension device life-span.Close, cut off the gas output in the solenoid valve, finished the control function of solenoid valve.Serial port connects wireless wireless communication module 5, is responsible for communicating with mobile phone, realizes sending alerting signal to mobile phone.Electric power management circuit provides stable 5V voltage to power to single-chip microcomputer.The 12MHz crystal oscillator provides clock signal to single-chip microcomputer.The wireless communication module that wireless communication module 5 adopts ZXGM18 conduct and mobile phone to communicate.ZXGM18 is the gsm wireless double frequency modulator-demodular unit that ZTE Corporation releases, and is mainly voice transfer, short message transmission and data service wave point is provided.ZXGM18 is integrated complete radio circuit and the baseband processor of GSM have the input of module support voice and short message.Support GSM900/1800MHz two-frequency operation pattern; Support the PHASE2/2+ agreement; Support more perfect AT order; Built-in/external SIM connector, the built-in external 3VSIM card of all supporting externally also can be supported the 5VSIM card by circuit; Supply voltage: 3.6V-4.5V; Emissive power: CLASSA (2W)/EGSM900, CLASSA (the 1W)/characteristics such as GSM1800, its performance satisfies system requirements.
