Abstract

The utility model relates to a taxi anti-rob self-saving system. The utility model is characterized in that the utility model consists of an evidence recording and distress circuit, a high voltage electricity retaliating circuit and a wireless alarm circuit. The evidence recording and distress circuit consists of a video memory chip IC1, a voice distress chip IC2, an optical camera, a miniature microphone, a key SA1, a sound velocity modulation resistance and a loudspeaker B. The high voltage electricity retaliating circuit consists of a threshold chip IC3, a key SA2, a slide rheostat RP, a capacitor C1 to C3, a dynatron VT, an inductance coil L1 to L4, a resistor R1 to R3, a diode VD1 to VD6 and a thyristor VS. The wireless alarm circuit comprises a chip IC4, a transmitting antenna, an inductance coil L5 and L6, a capacitor C4 to C6 and a key SA3 and so on. The utility model is provided with the functions of self defense, recording evidence of crime and wireless alarm. The design cost of the circuit is low and the installation is simple.

Description

The anti-system of saving oneself of plundering of a kind of taxi

Technical field

The utility model relates to a kind of system of saving oneself, and is the anti-system of saving oneself of plundering of a kind of taxi specifically.

Technical background

Taxi experience robbery is soaring in recent years, the defensive appliance of not having in crime reason and the car is relevant, for guaranteeing to drive indoor security, the utility model especially from quick radiowarning, record the evidence of crime equal angles, for human pilot designs the self-salvage system of a cover.

Summary of the invention

The purpose of this utility model provides the anti-system of saving oneself of plundering of a kind of taxi.

The technical solution of the utility model is: the anti-system of saving oneself of plundering of a kind of taxi, it is characterized in that it records and call for help circuit by evidence, the radiowarning circuit constitutes, described evidence is recorded and called for help circuit and calls for help chip IC 2 and chip periphery element by video storage chip IC 1, voice: optics pickup camera, mini microphone, telegraph key SA1, velocity of sound modulation resistance R, loudspeaker B constitute; Described radiowarning circuit is by chip IC 3, emitting antenna, telefault L1, formations such as L2, capacitor C1～C3, telegraph key SA2.

The new power supply of this practicality is vehicle-mounted 12V direct current.

The beneficial effects of the utility model are: have quick formula radiowarning, record function such as evidence of crime, circuit design is with low cost, installs simply, is fit to generally promote.

Embodiment

In first embodiment shown in Figure 1, the anti-system of saving oneself of plundering of a kind of taxi, it is characterized in that it is recorded and called for help circuit by evidence, the radiowarning circuit constitutes, I zone among circuit such as Fig. 1 is recorded and called for help to described evidence, it is by video storage chip IC 1, chip IC 2 and chip periphery element called for help in voice: the optics pickup camera, mini microphone, telegraph key SA1, velocity of sound modulation resistance, loudspeaker B constitutes, the optics pickup camera, mini microphone is a circuit input apparatus, its respectively rate decide according to demand, video storage chip IC 1 when energising (when criminal implements behavior by the driver manually or pin when stepping on telegraph key SA1) carry out internally stored program, criminal is implemented to plunder sight to record and stores, collect evidence for public security department, speech chip IC2 energising when telegraph key SA1 is pressed, and with interior storage class as " help! Someone plunders! " electric signal by loudspeaker B pedestrian emergency towards periphery; II zone among described radiowarning circuit such as Fig. 1, chip IC 3 is core parts, its peripheral cell has emitting antenna, telefault L1, L2, capacitor C1～C3, key SA2 etc., telefault L1 wherein, L2 one end is connected with chip IC 3 output pins, one end is connected with antenna, include the SAW resonator in the described chip IC 3, the SAW wave filter, the RF amplifier, scrambler, circuit such as modulation and biasing control, T/S is emission mode/sleep pattern control mouth in the circuit, circuit is low-power consumption when static, if carrying out when related command is all invalid in the I zone, driver's command system can press (riding) telegraph key SA2, system's one-touch easy dialing 110 emergency this moment, this key Ying Shenyong can only in case of emergency use.

In second embodiment shown in Figure 2, the anti-system of saving oneself of plundering of a kind of taxi, it is characterized in that system circuit board (2) is installed in the casing (1), telegraph key SA1 (3), telegraph key SA2 (4), telegraph key are installed on the casing front, and power supply is directly used vehicle-mounted 12V direct current.
