Keywords and boolean syntax (USPTO or EPO format): seat belt searches these two words, or their plurals and close synonyms. "seat belt" searches this exact phrase, in order. -seat -belt searches for documents not containing either word.
For searches using boolean logic, the default operator is AND with left associativity. Note: this means safety OR seat belt is searched as (safety OR seat) AND belt. Each word automatically includes plurals and close synonyms. Adjacent words that are implicitly ANDed together, such as (safety belt), are treated as a phrase when generating synonyms.

Chemistry searches match terms (trade names, IUPAC names, etc. extracted from the entire document, and processed from .MOL files.)
Substructure (use SSS=) and similarity (use ~) searches are limited to one per search at the top-level AND condition. Exact searches can be used multiple times throughout the search query.
Searching by SMILES or InChi key requires no special syntax. To search by SMARTS, use SMARTS=.

Car alarm with remote-control starting function
Description
translated from
Technical field
The present invention relates to car alarm field, espespecially a kind of car alarm of remote control start-up performance.
Background technology
Current, the startup of automobile is mainly that the method by mechanical lock knob realizes, and realizes the startup of car engine by artificial control.The advantage of this starting method is simple and reliable, but cannot realize the object of Based Intelligent Control, and each driver is different to the control of automobile starting firing point time, accelerates car engine to damage.Along with scientific and technological progress and development, people have worked out a kind of technology, pattern by one-way communication drives automobile starting, thereby realize the object that Based Intelligent Control starts automobile, but there is a drawback in the method for this one-way communication mode activated automobile starting, unidirectional due to communication mode, easily by lawless person by various intercepting device intercepts signals, copy a same remote controller and steal car.
Summary of the invention
For addressing the above problem, the invention provides a kind of car alarm of remote control start-up performance.
For achieving the above object, the technical solution used in the present invention is: the car alarm that a kind of remote control start-up performance is provided: comprise hand-held remote controller, power circuit, receiver carried by automobile, vehicle-mounted actuator, Vehicle Controller, engine management system and engine starting system; Described power circuit is connected with automobile storage battery, is described receiver carried by automobile, vehicle-mounted actuator, and Vehicle Controller, engine management system provides electricity consumption power supply; The input end of described vehicle-mounted actuator is connected with the mouth of described receiver carried by automobile, and mouth is divided into two ends, and one end is connected with described Vehicle Controller input, and the other end is connected with described engine starting system; Described engine starting system input end is connected with vehicle control syetem, and mouth is connected with engine starting system.
Wherein, described hand-held remote controller comprises battery, HF transmitter, an ECU process chip, low frequency receptor; Described ECU process chip input end is connected with described low frequency receptor, and mouth is connected with HF transmitter.
Wherein, described receiver carried by automobile comprises high-frequency receiver and low frequencies device; Described vehicle-mounted actuator comprises the 2nd ECU process chip, is connected with described receiver carried by automobile.
Wherein, described engine management system is ECM module, for calculating and control best fuel charge and igniting opportunity of engine
Wherein, described engine starting system comprises starting relay, is connected with automotive ignition starting switch circuit.
Wherein, described Vehicle Controller comprises: door lock controller, alarm controller; Described door lock controller comprises door lock relay, is connected with door switch circuit; Described alarm controller comprises indicating light relay and horn relay, is connected respectively with indicator light switch circuit with horn switch circuit.
Beneficial effect of the present invention is, replace the method that traditional manual mechanical knob starts automobile, adopt double frequency recognition technology to carry out remote control startup to automobile, wherein add ECM module, can calculate and control best fuel charge and igniting opportunity of engine, reach and reduce to greatest extent the loss that auto activation engine produces; In addition, double frequency recognition technology of the present invention can effectively prevent that lawless person from stealing transmitting of remote controller, and behavior effectively avoids theft.
Accompanying drawing explanation
Fig. 1 is functional block diagram of the present invention.
The specific embodiment
Refer to shown in Fig. 1, the present invention, about a kind of car alarm of remote control start-up performance, comprises hand-held remote controller, power circuit, receiver carried by automobile, vehicle-mounted actuator, Vehicle Controller, engine management system and engine starting system; Described power circuit is connected with automobile storage battery, is described receiver carried by automobile, vehicle-mounted actuator, and Vehicle Controller, engine management system provides electricity consumption power supply; The input end of described vehicle-mounted actuator is connected with the mouth of described receiver carried by automobile, and mouth is divided into two ends, and one end is connected with described Vehicle Controller input, and the other end is connected with described engine starting system; Described engine starting system input end is connected with vehicle control syetem, and mouth is connected with engine starting system.
Car owner uses a teleswitch and inputs the startup control signal of automobile, by an ECU process chip, the signal of input is encrypted and exports high-frequency radiator to, high-frequency radiator sends this coded signal by antenna, be arranged on receiver carried by automobile in automobile and by high-frequency receiving device, receive the 2nd ECU process chip that exports vehicle-mounted actuator after coded signal to, coded signal is carried out to decrypted authentication for the first time, if signal is by authentication, ECU process chip generates coded signal again, again by the low frequencies device transmitting plus signal of receiver carried by automobile, by remote controller medium and low frequency receiving device, receiving signal exports coded signal described in an ECU process chip to and authenticates for the second time, if by authentication, the 2nd ECU process chip output control command is to the starting relay of engine starting system, make its closed automobile that starts, simultaneously more defeated instruction to Vehicle Controller, control engine control system ECM starts, calculate and control best fuel charge and igniting opportunity of engine, the startup of realization to automobile the best.
The present invention also has the function entering without key, when if the remote controller that car owner carries enters the range of receiving with receiver carried by automobile, remote controller and Vehicle Controller exchange after authentication by mutual information, and vehicle-mounted actuator output control command is controlled door lock relay closes car door to Vehicle Controller just can auto-unlocking.
In addition, while illegally being opened car door by force when not having process remote controller and vehicle-mounted actuator two-frequency signal to exchange, vehicle-mounted actuator just can be controlled alarm relay closure by output command to Vehicle Controller, automobile flashing indicator light and the loudspeaker that ring, an anti-theft function.
Above embodiment is only that the preferred embodiment of the present invention is described; not scope of the present invention is limited; design under the prerequisite of spirit not departing from the present invention; various distortion and improvement that the common engineering staff in this area make technical scheme of the present invention, all should fall in the definite protection domain of claims of the present invention.
