The alarm comprises a power supply circuit, a test signal generation and signal processing circuit, a test signal amplitude limiting protective circuit, a test signal filtering and amplifying circuit and a test signal detection circuit. Two lines extend from a connector J10 and are connected to the positive and the negative electrodes of a connection circuit of a battery jar and a charging machine and also connected to the power supply circuit. A generated test signal is inputted to the connector J10 and is outputted from the connector J10. A test return signal from the connector J10 goes through the amplitude limiting protective circuit and then goes through the filtering and amplifying circuit. A DC signal related to the change of impedance in the connection circuit of the battery jar and the charging machine is detected by the test signal detection circuit. A single chip microcomputer (MCU) chip IC2 makes a judgment and drives a warning horn.

Background technology
Current science and technology development has proposed more and more higher requirement to the uninterrupted power supply of power supply.Typically be applied in the mobile communication, owing to the public improves the requirement of mobile communication, mobile communication operating company need build a large amount of mobile communication base stations, and it much is to build in unmanned spacious place that these base stations have; Be to guarantee communication, must there be back-up source the base station except the normal power supply system, guarantee at normal power supply once when having a power failure the base station can guarantee proper communication.These back-up sources all are made up of big capacity storage battery and management of charging and discharging circuit, wherein jumbo storage battery is expensive, because stolen phenomenon often takes place in the base station unmanned, the supervisory system of base station, the stolen back of storage battery can not be discovered at once, normal power supply is once have a power failure, the base station namely quits work, and causes except the material thing loss of equipment such as storage battery, and the communication time-out causes mobile communication to interrupt.Because the storage battery anti-theft technique not only requires sensitivity, accurately, also require to install hidden, easy, currently domesticly preventing that the stolen measure of storage battery of unmanned base station from being zero.
Summary of the invention
Based on above-mentioned situation, the utility model provides a kind of battery anti-theft alarm of unmanned back-up source, to solve the existing stolen problem of unmanned base station storage battery.
The technical scheme that its technical matters that solves the utility model adopts is that alarm is made up of power circuit, test signal generation and signal processing circuit, test signal limiter protection circuit, test signal filter amplification circuit and test signal detecting circuit; Power circuit is by transistor Q1, transistor Q2, and integrated circuit (IC) 5, inductance L 1, crystal diode D5, capacitor C 14, integrated circuit (IC) 4 is formed; Test signal produces and signal processing circuit mainly is made up of a single-chip microprocessor MCU chip integrated circuit (IC) 2 and peripheral cell, form limiter protection circuit by crystal diode D3, crystal diode D4, capacitor C 2, capacitor C 9, form filter amplification circuit by integrated circuit (IC) 1, integrated circuit (IC) 3, resistance R 1, resistance R 3, capacitor C 1, capacitor C 5; Detecting circuit is made up of crystal diode D1, crystal diode D2, capacitor C 8, resistance R 7; Connector J10 externally is connected on the positive and negative electrode of storage battery and charging set link circuit; be connected internally to power circuit, test signal generation and signal processing circuit and to being connected with test signal limiter protection circuit, test signal filter amplification circuit and test signal detecting circuit between the outconnector J10.Constitute the integrated circuit that newspaper advances alert device.
Adopt effect of the present utility model to be: easy for installation, volume is little, and the installation site is hidden easily, and it is stable to be active in one's movements, and power consumption seldom has good antitheft effect to the unattended storage battery in field.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is the utility model electrical block diagram;
1 power circuit, 2 test signal generations and signal processing circuit, 3 limiter protection circuits, 4 filter amplification circuit, 5 detecting circuits, 6 connector J10 among the figure.
Embodiment
As shown in the figure; Alarm is made up of 6 sub-circuit: (1) power circuit, (2) test signal produces and signal processing circuit, (3) limiter protection circuit, (4) filter amplification circuit, (5) detecting circuit.(6) connector.Adopt the SMT package technique to be assembled into a very little circuit board of volume alarm, put into a little rigid plastic box, pick out two lines by connector J10, just be connected to storage battery and charging set link circuit by J10 connector (6) among the figure, on the negative pole, because so alarm employing SMT technology making volume very I is installed in place more hidden in storage battery and the charging set link circuit, power circuit (1) is converted to other circuit of burning voltage supply alarm that is applicable to warning horn with the high voltage of storage battery after connecting, by transistor Q1, transistor Q2, integrated circuit (IC) 5, inductance L 1, crystal diode D5, C14 and peripheral cell are formed the switching regulator mu balanced circuit, and the heat that can reduce the power consumption of alarm and produce because of power consumption can make alarm reliablely and stablely work in wideer supply voltage scope; Test signal produces and signal processing circuit (2) mainly is made up of a single-chip microprocessor MCU chip IC 2 and peripheral cell, integrated circuit (IC) 2 utilizes the PWM generator of single-chip microcomputer to produce the test signal of a high frequency, adopting frequency in example is the test signal of 10KHz, and this signal is sent into connector J10(6 after capacitor C 16 stopping direct currents and resistance R 21 decay) be connected to the storage battery link circuit and make test signal and use; IC2 also judges whether to report to the police and report the master control center to the return signal of test signal simultaneously; The return signal of test signal is through connector J10(6) at first enter by crystal diode D3, crystal diode D4, capacitor C 2, capacitor C 9 and form limiter protection circuit (3), external high reject signal is carried out limited amplitude protection, to prevent the obstruction to subsequent conditioning circuit; Send into the filter amplification circuit of being formed by integrated circuit (IC) 1, integrated circuit (IC) 3, resistance R 1, resistance R 3, capacitor C 1, capacitor C 5 and peripheral cell (4) behind the test signal amplitude limit, the bandpass filter that filter amplification circuit (4) is made up of four operational amplifiers and peripheral cell, its Q value is higher, centre frequency is 10KHz in example, can well the useless interference signal of filtering, keep the stable, accurately of test signal; Test signal is sent into by crystal diode D1 after filtering is amplified, crystal diode D2, resistance R 7, the detecting circuit (5) that capacitor C 8 is formed obtains the direct current signal relevant with the impedance variation of circuit in storage battery and the charging set link circuit, the storage battery internal resistance is generally several milliohms even below a milliohm under the normal condition, and the output impedance of circuit for charging machine has more than the Europe, this alarm is as long as the impedance of observation circuit in storage battery and charging set link circuit, the AC impedance of circuit equals the impedance of storage battery under the normal condition, for several milliohms even below a milliohm, the impedance of link circuit will increase when preparing the theft storage battery once the thief gets loose the storage battery connecting line, the return signal of test signal will increase, after filtering is amplified, the output direct current signal of detecting circuit (5) will increase, single-chip microprocessor MCU chip IC 2 is made accordingly and is judged that starting the loudspeaker warning threatens the thief, can report the master control center by pilot signal simultaneously.
