Abstract

The invention discloses an antitheft alarm device for a school computer machine room, comprising an antitheft alarm device housing which is internally provided with a microcontroller, a charging interface circuit, a satellite antenna, a GPS positioning module, an alarm buzzer, a GPRS module, a time-delay circuit used for determining the alarm duration of the alarm buzzer, an audio frequency processing circuit connected to the alarm buzzer, a drive circuit used for driving the audio frequency processing circuit to work, and a reset circuit used for resetting the microcontroller in case of mis-alarm. The antitheft alarm device has the characteristics of simple structure, convenient installation and layout and low investment cost; when burglary occurs, the alarm buzzer shrills to horrify burglars, the GPRS module sends alarm messages to monitoring personnel in real time, and the GPS positioning module tracks and positions the burglars, thereby effectively solving the problems that a current monitoring system is high in investment cost, and can not respond the moment burglary occurs.

Description

A kind of the computer classroom burglar alarm
Technical field
The present invention relates to a kind of burglar alarm, especially relate to a kind of the computer classroom burglar alarm.
Background technology
Computer in the computer classroom is large number of, if occurring stolen, without causing bigger economic loss, and student can be about to the course that carries out and produce considerable influence, cause teacher because cannot use computer and must not uncomfortable class, upset normal order in education.
The image that traditional machine room monitoring system is typically only machine room is on-the-spot is sent to Surveillance center's computer screen, so just requiring that control room must adopt personnel's post in 24 hours.Such mode has not only increased the weight of the burden of operator on duty, and is very easy to careless omission occur, causes that stolen problem is not immediately available response, and stolen after be difficult to thief is tracked.
Summary of the invention
The technical problem to be solved is in that for above-mentioned deficiency of the prior art, a kind of the computer classroom burglar alarm is provided, its simple in construction, installation are laid conveniently, input cost is low, thief can not only be produced effective threatening by work, and thief can be positioned tracking.
nullFor solving above-mentioned technical problem,The technical solution used in the present invention is: a kind of the computer classroom burglar alarm,It is characterized in that: include burglar alarm housing,In described housing, microcontroller is installed、Charging inlet circuit、For receiving the satellite antenna of gps signal、For the position of host computer in computer room is carried out pinpoint GPS locating module、Jangle sound thief to be produced the alarm buzzer of scaring effect when mobile outside described host computer is expected、On the mobile phone specify monitoring personnel, the GPRS module of alarming short message is sent when mobile outside described host computer is expected、For determining the delay circuit of the warning duration of described alarm buzzer、The audio frequency processing circuit connected with described alarm buzzer、For drive drive circuit that described audio frequency processing circuit works and in time there is false alarm reset circuit for microcontroller is resetted;Described burglar alarm housing is fixed on the cabinet inwall of described host computer and is positioned at the opposite of computer main board, housing offers wiring hole, the cabinet outer wall of described host computer is laid with SR, described SR is connected with described reset circuit by wire louvre on described cabinet, described microcontroller and GPS locating module all connect with charging inlet circuit, described charging inlet circuit is connected with the host power supply on described computer main board through described wiring hole by wire, described satellite antenna, GPS locating module, microcontroller, GPRS module connects successively, described drive circuit connects with microcontroller and audio frequency processing circuit respectively, described delay circuit and reset circuit all connect with microcontroller, described mobile phone and GPRS module wireless connections.
Above-mentioned a kind of the computer classroom burglar alarm, is characterized in that: described microcontroller is STM32F103MCU.
Above-mentioned a kind of the computer classroom burglar alarm, is characterized in that: the movement outside described expection is mobile 0.5 meter.
Above-mentioned a kind of the computer classroom burglar alarm, is characterized in that: described burglar alarm housing is pasted onto on the outer wall of described cabinet relatively shelter.
Above-mentioned a kind of the computer classroom burglar alarm, is characterized in that: the model of described GPS locating module is H-8123.
The present invention compared with prior art has the advantage that simple in construction, installation laying is convenient, input cost is low;When there is theft, thief is threatened by the alarm buzzer sound that jangles, GPRS module sends alarming short message to monitoring personnel in real time, the place of runing away of thief is positioned tracking by GPS module, efficiently solve existing monitoring system input cost high, the problem occurring can not obtain making an immediate response during theft.
Below by drawings and Examples, technical scheme is described in further detail.
