Abstract
Disclosed is an induction-type anti-theft alarm which is characterized in that the blue line of the main unit of the induction-type anti-theft alarm is connected with a trigger; the white line of the main unit of the induction-type anti-theft alarm is connected with an igniter; a 12V storage battery and a switch are serially connected with the red line of an NC 555 control chip; the oscillator of a transmitter, a diode and a 1UF capacitor are serially connected. When the switch of the induction-type anti-theft alarm is on and the transmitter exceeds the range of the main unit in 2 meters, the NC555 control chip inducts no trigger signal from the gray receiving antenna, and then the NC555 transmits the electric energy of the storage battery to a loudspeaker through the orange line and the yellow line, so as to control the loudspeaker to send alarm; meanwhile, the blue line is disconnected with the white line; thereby, the engine cannot be started and the control function of anti-theft alarm is realized.
Description
Technical field
The utility model relates to a kind of anti-theft system of self-propelled vehicle, is a kind of induction type anti-theft alarm device concretely.
Background technology
At present, motor bike generally adopts remote annunciator to be used as the overwhelming majority that accounted for of anti-joyride device, this mechanism simple structure, easy to maintenance, but there is obvious weak point: because there is flase alarm in remote annunciator, annunciator main frame power consumption during vehicle immobilization is because of flase alarm and main frame power consumption cause the vehicle battery power consumption to cause that totally vehicle can not start.
The utility model content
The purpose of this utility model is to provide a kind of induction type anti-theft alarm device, make and guaranteeing on the simply constructed basis of former anti-theft system, also have the elimination flase alarm, the not power consumption of vehicle immobilization main frame can be used as the induction type anti-theft alarm device of the anti-theft system of motor bike.
The utility model is realized with following technical scheme: this induction type anti-theft alarm device mainly is made of main frame and emitter, and main frame is made up of magneto generator, binary pair, firing unit, high-voltage ignition coil, NC555 control chip, diode, switch, 12V storage battery, receiving wire, loud speaker; Emitter is made up of 1.5V storage battery, oscillator, diode, 1UF cond.It is characterized in that: the blue line of induction type anti-theft alarm device main frame is connected with binary pair, the white wire of induction type anti-theft alarm device main frame is connected with firing unit, 12V storage battery, switch are connected with the red line of NC555 control chip, the oscillator of emitter, diode, 1UF capacitors in series.The electric energy of 12V storage battery is supplied electric energy by red line and green line to the induction type anti-theft alarm device under the situation of switch conduction, the grey receiving wire receives induction type anti-theft alarm device emitter in 2 meters efficient ranges to be power supply after the oscillator concussion by the 1.5V storage battery form the loop with the control chip of NC555 by diode rectification more over the ground behind the signal that 1UF electric capacity is launched, blue line and white wire conducting, magneto generator rotation behind the engine starting, the energizing signal that binary pair produces offers induction type anti-theft alarm device in-to-in NC555 control chip, the NC555 control chip is transported to the inside of firing unit by white wire, to realize the igniting of high-voltage ignition coil; Behind switch conduction, emitter surpasses 2 meters scopes of main frame, the NC555 control chip does not have the energizing signal of perception grey receiving wire, NC555 will be transported to loud speaker to the electric energy of storage battery by orange line and yellow line, thereby blue line of the warning of control loudspeaker while and white wire will be disconnected, driving engine can not start, and has realized the controllable function of anti-theft alarm.
Compared with the prior art, use this induction type anti-theft alarm device can solve the flase alarm of remote annunciator, vehicle does not have drawbacks such as the remote annunciator of startup main frame power consumption.
In sum, just because of this induction type anti-theft alarm utensil has the flase alarm that solves remote annunciator, vehicle does not have the power consumption of the remote annunciator of startup main frame, the storage battery power consumption function totally that causes, thereby the service life of prolongation storage battery.
Description of drawings
Fig. 1 is the fundamental diagram of the utility model induction type anti-theft alarm device.
The specific embodiment
Fig. 1 is the fundamental diagram of the utility model induction type anti-theft alarm device, its principle of work is to be made of main frame and emitter, and main frame is made up of magneto generator, binary pair, firing unit, high-voltage ignition coil, NC555 control chip, diode, switch, 12V storage battery, receiving wire, loud speaker; Emitter is made up of 1.5V storage battery, oscillator, diode, 1UF cond.In Fig. 1, the blue line of induction type anti-theft alarm device main frame is connected with binary pair, the white wire of induction type anti-theft alarm device main frame is connected with firing unit, and 12V storage battery, switch are connected with the red line of NC555 control chip, the oscillator of emitter, diode, 1UF capacitors in series.The electric energy of 12V storage battery is supplied electric energy by red line and green line to the induction type anti-theft alarm device under the situation of switch conduction, the grey receiving wire receives induction type anti-theft alarm device emitter in 2 meters efficient ranges to be power supply after the oscillator concussion by the 1.5V storage battery form the loop with the control chip of NC555 by diode rectification more over the ground behind the signal that 1UF electric capacity is launched, blue line and white wire conducting, magneto generator rotation behind the engine starting, the energizing signal that binary pair produces offers induction type anti-theft alarm device in-to-in NC555 control chip, the NC555 control chip is transported to the inside of firing unit by white wire, to realize the igniting of high-voltage ignition coil; Behind switch conduction, emitter surpasses 2 meters scopes of main frame, the NC555 control chip does not have the energizing signal of perception grey receiving wire, NC555 will be transported to loud speaker to the electric energy of storage battery by orange line and yellow line, thereby blue line of the warning of control loudspeaker while and white wire will be disconnected, driving engine can not start, and has realized the controllable function of anti-theft alarm.
