Description

A kind of alarms and security systems for automobiles

Technical field

The utility model relates to anti-theft device, is specifically related to a kind of alarms and security systems for automobiles.

Background technology

At present, alarms and security systems for automobiles on the market, mainly be to utilize key to open the door, lock a door and start, recently also by utilizing wireless signal to open the door at a distance, lock a door and start, but the thief still can utilize and open key case and start automobile and steal, particularly some people can go out because of urgent thing, can forget to lock door between hasty, the result has made a lot of robber's car chances to the thief, and general automobile burglar equipment mainly is the warning device that adopts sound, and these are equipped in few people, unmanned area, the effect that is produced is limited, the thief is after destroying car door, and form is destroyed the audible alarm circuit by force, equally can stolen car, to so far, also do not have a kind ofly can be directly to prevent the device that automobile is stolen according to user's exclusive information.

The utility model content

The purpose of this utility model is the shortcoming at prior art, and a kind of starter motor of direct Control of Automobile is provided, and utilizes the user's of fixed transmission on automobile key and the telepilot exclusive identification signal could start the alarms and security systems for automobiles of automobile.

The technical scheme that provides of the present utility model is as follows: construct a kind of alarms and security systems for automobiles, comprise a wireless signal acquiring device and a controller, also comprise a telepilot to described wireless signal acquiring device transmission identification signal, be provided with the power circuit that connects according to the signal Processing connection-related electricity use in the described controller, the wireless signal receiver module, microprocessor, voice warning circuit, clock oscillation circuit and control relay circuit, described telepilot sends identification signal, after described wireless signal acquiring device will receive signal fusing, send control signal to described controller, circuit is connected in the work of controller drives control relay circuit.

Described wireless signal acquiring device is the corresponding wireless signal transmitting module of mode of operation that comprises wireless signal receiver module in selected on-off circuit, LED warning light power supply, single-chip microcomputer, signal pickup assembly and the controller; The signal pickup assembly that uses in the described wireless signal acquiring device is the electronic signal harvester that can gather the personal information of autoist, and this personal information comprises: fingerprint, Zhou Shengbo and iris; Its output terminal directly with the wireless signal acquiring device in dynamo-electric linking to each other of monolithic; Use in the described controller microprocessor be the 16F54 single-chip microcomputer; The single-chip microcomputer that uses in the described wireless signal acquiring device is the PT2262 single-chip microcomputer.

The utlity model has following advantage: because the utility model is directly to be connected with the mode of start-up circuit series connection, key that must automobile and predefined user's peculiar information just can start automobile, rather than adopt traditional audible alarm unit, improved antitheft performance greatly; Because the design of internal processes, before use, necessarily require the driver to preestablish the identification signal of controller, sound as the user, wait in use, require the wireless signal acquiring device and the predefined voice signal three of user of automobile key, recognizer could start automobile, even such design makes the thief have the wireless signal acquiring device and car key also can't start automobile, theftproof performance is very superior.

Embodiment

Below in conjunction with accompanying drawing concrete embodiment is illustrated:

As Fig. 3, Fig. 4 and shown in Figure 5,: a kind of alarms and security systems for automobiles, comprise wireless signal acquiring recognizer and controller, controller is to comprise power circuit, wireless signal receiver module, microprocessor, voice warning circuit, clock oscillation circuit and the control relay circuit that is electrically connected in regular turn.

Described wireless signal acquiring device is the corresponding wireless signal transmitting module of mode of operation that comprises wireless signal receiver module in selected on-off circuit, LED warning light, single-chip microcomputer, signal pickup assembly and the controller; The signal pickup assembly that uses in the described wireless signal acquiring device is the electronic signal harvester that can gather the personal information of autoist, and this personal information comprises: fingerprint, Zhou Shengbo and iris; Its output terminal directly with the wireless signal acquiring device in dynamo-electric linking to each other of monolithic; Use in the described controller microprocessor be the 16F54 single-chip microcomputer; The single-chip microcomputer that uses in the described wireless signal acquiring device is the PT2262 single-chip microcomputer.

The system works principle:

As shown in Figure 1, the wireless signal acquiring recognizer passes through signal pickup assembly, collect user's personal information, by selected on-off circuit, after the user selects unlock switch, the user's who collects personal information is passed through signal pickup assembly, be transferred in the single-chip microcomputer, then by single-chip microcomputer, convert specific signal to after, be transferred to wireless signal transmitting module, send specific signal, can light LED light simultaneously, with the collection of expression signal and the transmission success of signal; Signal receiving module on controller, after having received the signal of the personal information above the wireless signal acquiring device, can utilize the clock circuit above the master control computer, the countdown that enters 1 minute, in 1 minute time, wireless signal can be by the microprocessor above the controller, the identification signal contrast that stores in the identification signal of current acceptance and the Prior Control device, after the affirmation unanimity, the microprocessor of controller can send signal to the control relay circuit in the relay, make control loop be communicated with, control voice warning circuit simultaneously, send information, this time by checking, the user only need insert car key, just can start automobile.If the identification signal that stores in the identification signal of current acceptance and Prior Control device contrast, the result of checking is inconsistent, and then microprocessor can not be communicated with relay, and the loop is not communicated with, and inserts car key and can not start automobile.Certainly, if the result of checking is consistent, but in one minute countdown, the user does not insert car key and starts automobile, after countdown finishes, inserts car key and can not start automobile, needs operation again once.When not needing to use automobile, can utilize the off signal above the telepilot, can control the microprocessor on the controller, by the control circuit cut-off loop of microprocessor indicating relay, automobile can stop working.

As shown in Figure 2, wait when mounted, must the controller in the alarms and security systems for automobiles according to the circuit connection diagram, be connected in the automotive interior circuit, then according to subsidiary at random operation instruction, each user's personal information of automobile is used in input; As voice signal, iris signal or fingerprint signal, in the time of use, open car door by key, press the unlock button above the telepilot then, input user's personal information; As voice signal, iris signal or fingerprint signal, in 1 minute of program setting, insert car key, recognizer can be according to the personal information of input and the personal information that stored originally contrast, confirm errorless after, can send the auditory tone cues signal of affirmation, the startup automobile.Travel after the end, the key of can back-outing is pressed the locking button above the wireless signal acquiring device, automobile can enter anti-theft state, certainly, also can directly press the locking button above the wireless signal acquiring device, in the setting-up time of program, automobile also can enter anti-theft state.
