Background technology

Scientific Research in University Laboratory, is the important place that the teachers and students of university carry out practical activity, is often placing the computing machine of some important experimental apparatuss and One's name is legion, therefore, antitheft, and fire prevention just seems extremely important.The safety of traditional experiment chamber often relies on operator on duty to go on patrol, monitor to guarantee, such security measure was both wasted time and energy, and cannot reach again timely and effectively fire prevention, antitheft object.

Utility model content

The purpose of this utility model is to provide a kind of fire-proof and theft-proof warning device based on GSM, fire prevention, function antitheft and that report to the police can be integrated in one, and carries out safeguard protection effectively for laboratory.

The technical scheme that the utility model adopts is: the laboratory fire-proof and theft-proof warning device based on GSM, comprise control module, control module is connected with respectively temperature sensor, A/D modular converter, infrared sensor, keyboard, memory module, sound and light alarm module and gsm communication module, and A/D modular converter is also connected with smoke transducer.

Control module is connected with display module.

Control module is connected with clock module.

Control module adopts the single-chip microcomputer that model is STC89C52.

The model of temperature sensor is DS18B20.

The beneficial effects of the utility model are: the situation that temperature, smokescope and the personnel of monitoring experiment chamber enter laboratory in real time of the fire-proof and theft-proof warning device based on GSM of the present utility model, and according to circumstances send real-time information by the mode of note or phone to staff, realize Realtime Alerts and remote alarms.

Accompanying drawing explanation

Fig. 1 is the structural representation of the laboratory fire-proof and theft-proof warning device based on GSM of the present utility model.

In figure, 1. control module, 2. temperature sensor, 3. smoke transducer, 4.A/D modular converter, 5. infrared sensor, 6. keyboard, 7. memory module, 8. sound and light alarm module, 9.GSM communication module, 10. display module, 11. clock modules.

Embodiment

Below in conjunction with accompanying drawing and embodiment, the utility model is elaborated.

The utility model provides a kind of laboratory fire-proof and theft-proof warning device based on GSM, as shown in Figure 1, comprise control module 1, control module 1 is connected with respectively temperature sensor 2, A/D modular converter 4, infrared sensor 5, keyboard 6, memory module 7, sound and light alarm module 8 and gsm communication module 9, and A/D modular converter 4 is also connected with smoke transducer 3.

Control module 1 is connected with display module 10.

Control module 1 is connected with clock module 11.

It is the single-chip microcomputer of STC89C52 that control module 1 adopts model.

The model of temperature sensor 2 is DS18B20.

The laboratory fire-proof and theft-proof warning device course of work based on GSM of the present utility model is as follows: staff inputs by keyboard 6 password of deploying troops on garrison duty setting in advance, password transmission is to control module 1, control module 1 is sent the signal of startup to temperature sensor 2, A/D modular converter 4, infrared sensor 5, memory module 7 and sound and light alarm module 8 respectively, above-mentioned modules is started working, and laboratory fire-proof and theft-proof warning device enters the state of deploying troops on garrison duty.

Staff also can send default control information to gsm communication module 9 by mobile phone, gsm communication module 9 by the control information receiving by transferring to control module 1, control module 1 is sent the signal of startup to temperature sensor 2, A/D modular converter 4, infrared sensor 5, memory module 7 and sound and light alarm module 8 respectively, above-mentioned modules is started working, and laboratory fire-proof and theft-proof warning device enters the state of deploying troops on garrison duty.

Wherein the effect of A/D modular converter 4 is to carry out the conversion between digital signal and simulating signal between control module 1 and smoke transducer 3, enter after the state of deploying troops on garrison duty at above-mentioned laboratory fire-proof and theft-proof warning device, the extraneous smokescope analog signal transmission that smoke transducer 3 senses is to A/D modular converter 4, above-mentioned simulating signal is converted to digital signal by A/D modular converter 4, then by this digital data transmission to control module 1.

When this laboratory fire-proof and theft-proof warning device is in the time deploying troops on garrison duty state, the moment is transmitted corresponding outer signals to control module 1 respectively for temperature sensor 2, smoke transducer 3, infrared sensor 5 and sound and light alarm module 8.

In the time of the breaking out of fire of laboratory, temperature sensor 2 and smoke transducer 3 sense that respectively extraneous temperature and smokescope have exceeded predefined threshold value, so temperature sensor 2 directly sends the too high signal of ambient temperature to control module 1, extraneous smokescope signal is transferred to A/D modular converter 4 by smoke transducer 3 simultaneously, A/D modular converter 4 converts above-mentioned smokescope signal to digital data transmission to control module 1, control module 1 receives after excess Temperature signal and the too high signal of smokescope, send alerting signal to sound and light alarm module 8, sound and light alarm module 8 is sent and is piped and luminous alarm, remind staff to control in time the condition of a fire, control module 1 is given laboratory personnel's on duty mobile phone dialing phone and is sent warning message by gsm communication module 9 simultaneously.

In the time having people to enter laboratory, infrared sensor 5 detects the infrared information that human body sends, can send and have people to enter the signal in laboratory to control module 1, the current time that control module 1 transmits by clock module 11, judgement is in working or next state, if the work hours, control module 1 sends to staff the signal that someone enters by gsm communication module 9, whether staff observes by display module 10 personnel of entering and is allowed to, and takes afterwards the measure of letting pass or inquiring again; If current in the quitting time, control module 1 sends to staff the signal that someone enters by gsm communication module 9, and control module 1 is sent alerting signal to sound and light alarm module 8 simultaneously, and sound and light alarm module 8 is sent and piped and luminous alarm.

The information of transmitting between above modules and control module 1, all can be stored in memory module 7, in order to checking at any time.

By the way, fire-proof and theft-proof warning device based on the GSM situation that temperature, smokescope and the personnel of monitoring experiment chamber enter laboratory in real time of the present utility model, and according to circumstances send real-time information by the mode of note or phone to staff, realize Realtime Alerts and remote alarms.
