Description

The apparatus for protecting power supply of space wireless anti-theft fire-fighting citation main frame

Technical field:

The utility model relates to a kind of apparatus for protecting power supply of space wireless anti-theft fire-fighting citation main frame; especially refer to a kind ofly can produce and switch to a stand-by power supply power supply when unusual, and notify the related personnel to produce the apparatus for protecting power supply that caution is moved simultaneously with mobile phone short message in saving normal power supply with antitheft fire-fighting main frame from damage.

Background technology:

Complicated along with social environment, various public security problems emerge in an endless stream, wherein general and serious for common people's safety and property loss with deathwatch's problem again, therefore, the anti theft host with various detecting functions is widely used in each family, factory or other space to be saved from damage.Common small-sized anti theft host, it can cooperate various detection element (as: magnetic reed switch, body temperature and ultrasound sensors) with sensing illegal invasion person, and can drive a high-decibel siren (if only building dwelling house) according to setting, to produce the alarm sound of tool scare function via this high-decibel siren, or be attached to a caretaker room (if sub-district dwelling house) with circuit in addition, handle accordingly with the operator on duty who notifies this caretaker room; Other has progressive, and it is that smoke detector, calling for help switch etc. is integrated in this detection element the simple and easy security function that this anti theft host is prevented with general fire in addition.

Yet above-mentioned simple and easy small-sized anti theft host is when practical application, and (as: in only building in no adjacent room dwelling house, the scare function that this alarm sound produced is limited except many inapplicable occasions or disappearance are arranged; Or the operator on duty of caretaker room horizontally-arranged or carelessness away from keyboard and delayed response) outside, more because this anti theft host and associated component thereof all adopt single power supply (and general civil power) electric power system, unless therefore dispose a non-interruption power supply device (UPS) more separately, when external power source (civil power) supply (has a power failure or artificial destruction) unusually, can provide standby power supply, otherwise, this burglary-resisting system integral body then can be difficult to keep normal operation in default of power supply, more can't bring into play due antitheft or security function, this is the serious disappearance on using.

Because the known small-sized antitheft main frame of saving from damage has above-mentioned shortcoming, the creator is the road at those shortcoming research improvement, has the utility model to produce finally.

The utility model content:

Technical problem to be solved in the utility model is: at above-mentioned the deficiencies in the prior art; a kind of apparatus for protecting power supply of space wireless anti-theft fire-fighting citation main frame is provided; it is when outside main power source (civil power) abnormal electrical power supply; can switch to a stand-by power supply synchronously, to keep the normal operation of total system.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of apparatus for protecting power supply of space wireless anti-theft fire-fighting citation main frame, be characterized in: this device comprises at least: a main power source detecting module, be electrically connected on the main power source of outside main power supply, state for this main power source of detecting, and when the voltage of this main power source is lower than a default value, produce a detection signal; One microprocessing unit, it is linked in this main power source detecting module, and connects with a stand-by power supply, accepting the detection signal of this main power source detecting module output, and switches to stand-by power supply power supply after handling by analysis, produces a control signal simultaneously; One action communication module is linked in this microprocessing unit, and the Mobile Communications unit corresponding with the outside connects.

According to said structure, wherein this microprocessing unit connects a caution unit in addition, and this caution unit produces a caution sound when receiving the control signal of this microprocessing unit.

According to said structure, wherein this main power source detecting module mainly is made up of a reduction voltage circuit and a voltage detection circuit, this reduction voltage circuit is reduced to a reference voltage level with vehicle power supply, this voltage detection circuit is then detected this reference voltage level, and exports a detection signal to microprocessing unit when this reference voltage level is lower than a default value.

So, when this is installed on outside main power source (civil power) abnormal electrical power supply, can switch to a stand-by power supply synchronously, to keep the normal operation of total system; Simultaneously, can start an action communication module and send a wireless telecommunications message, carry out relative response and processing, to reduce various deathwatch or the unexpected chance that takes place to notify the related personnel.

For making above-mentioned purpose of the present utility model, effect and feature can obtain loud and clear more specifically separating, as follows according to following description of drawings now:
