Description
Technical field
The utility model relates to a kind of anti-theft alarm for electric appliance.
Background technology
The phenomenon of the power equipments such as China's pilferage at present or destruction line of electric force and transformer happens occasionally, and existing anti-theft alarm for electric appliance, its antitheft or vandal-proof detection means is more single, can only tackle one or two kind of theft and damage means, be still a large amount of power equipments that anti-theft device has been installed and destroyed or be stolen, existing electric anti-theft device is often because the impact of site environment causes the situation of report false-alarm simultaneously.More than existing burglar alarm, adopt power equipment directly for its power supply, in the time that electric power facility is destroyed or stolen, can only provide electric power supply in short-term for burglar alarm, reduced the validity of burglar alarm.
Utility model content
The purpose of this utility model is to provide a kind of anti-theft alarm for electric appliance, it can survey the sensor of existing main theft or sabotage of electrical power equipment mode according to above-mentioned defect being provided with, adopt multiple detection means to combine use, both improve the validity of reporting to the police, reduced again the situation of report false-alarm.
The purpose of this utility model realizes by following structure, it comprises: CPU (central processing unit), CPU (central processing unit) is connected with wireless communication module and power module, described CPU (central processing unit) connection detection circuit, testing circuit connects outage detection sensor, inclination sensor, infrared sensor and electric current induction pick-up, and testing circuit comprises: analog to digital conversion circuit and detection logic control CPLD.
Described power module connects battery, and battery connects solar opto-electronic board, and CPU (central processing unit) connects charging detecting circuit, and CPU (central processing unit) connects photoelectricity management relay.
Described CPU (central processing unit) connects the circuit of checking meter.
Described CPU (central processing unit) is provided with information output interface and input information interface.
The utility model adopts the polytype sensor being connected with testing circuit, in testing circuit, detect under the judgement of logic control CPLD, the wireless communication module connecting by CPU (central processing unit) and information output interface, warning message is sent to long-range control backstage or terminal, according to long-range main control system or terminal or on-the-spot prompting, find that as early as possible power equipment is in the hole by user.
Brief description of the drawings
Fig. 1 is the circuit theory diagrams of a kind of embodiment of the utility model.
Embodiment
The utility model comprises as shown in Figure 1: CPU (central processing unit), CPU (central processing unit) is connected with wireless communication module and power module, described CPU (central processing unit) connection detection circuit, testing circuit connects outage detection sensor, inclination sensor, infrared sensor and electric current induction pick-up, and testing circuit comprises: analog to digital conversion circuit and detection logic control CPLD.Described power module connects battery, and electric battery connects solar opto-electronic board, and CPU (central processing unit) connects charging detecting circuit, and CPU (central processing unit) connects photoelectricity management relay.Described CPU (central processing unit) connects the circuit of checking meter.Described CPU (central processing unit) is provided with information output interface and input information interface.CPU (central processing unit) adopts the AT89C52 single-chip microcomputer of American ATMEL, detects logic control CPLD and adopts the U.S. LC4128V of Lattice company chip.
Testing circuit circuit comprises: analog to digital conversion circuit and detection logic control CPLD, analog to digital conversion circuit is divided into 4 tunnels and is used for connecting respectively outage detection sensor, inclination sensor, infrared sensor and 4 dissimilar sensors of electric current induction pick-up, and the connected sensor of structure of Qie Ge road analog to digital conversion circuit adapts.Whether outage detection sensor is normal for detection of the current voltage of electricity consumption facility or electric current, inclination sensor is for detection of whether toppling on occurrence positions of power equipment, whether infrared sensor has abnormal infrared signal to change in power equipment week for judging, electric current induction pick-up is for being connected to power equipment electrified wire, meet with into wire fracture or directly cut off wire when burglar moves, can cause the wire variation in original magnetic field around, thereby send alarm command to detecting logic control CPLD.Detecting logic control CPLD can be according to the actual needs, according to certain Logic Priority level or syntagmatic, judge the alarm command that each sensor sends, when finally meeting after logic of propositions condition just to long-range backstage or terminal or onsite alarming device send final warning information.Adopt and detect logic control CPLD, can, according to field condition, carry out from new combination or optimization for judgement and the analysis of alarm command, be also convenient to some error-logics to modify, greatly improved adaptability and the maintainability of system.
Solar opto-electronic board is powered battery, and the voltage that battery detected when charging detecting circuit is during lower than 12V, CPU (central processing unit) is opened photoelectricity management relay, be battery charging by solar opto-electronic board, when CPU (central processing unit) was opened after photoelectricity management relay a period of time, the voltage that charging detecting circuit detects battery is during still lower than 12V, and CPU (central processing unit) produces battery and damages instruction.The mode that adopts battery and solar opto-electronic board cooperated power supply, can make warning device and power equipment work alone, and need to not obtain power supply from power equipment, has also reduced operating cost and the energy consumption of system simultaneously.
Wireless communication module is GSM communication module, alarm command and various exceptional instructions that it can produce CPU (central processing unit), send it back long-range control host machine or terminal by wireless network, long-range control host machine or terminal can be to user's display alarm information or device exception informations, to facilitate user to gather further step, improve the security of power equipment.
Described CPU (central processing unit) connects the circuit of checking meter, and is the power consumption that this device increases the power equipment of function statistics connection, conveniently uses in the relatively backward place of some power equipments, reduces the quantity of whole system equipment, improves the utilization factor of equipment.
CPU (central processing unit) is provided with information output interface and input information interface, information output interface is used for connecting loudspeaker or wired network interface or display, loudspeaker can provide on-the-spot audio alert, wired network interface can improve the transmission quantity with long-range control host machine information, and display can provide for user the device operation information of word or image-type; And input information interface is used for connecting the device such as keyboard or mouse, be convenient to running status of the present utility model to debug or some function setting.
