Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
By Fig. 1, Fig. 2, Fig. 3 as seen: the present invention includes: a hand-held remote controller, a mobile unit; Described hand-held remote controller comprises: the one 433 receive/send out module and the 1 and receive/send out module with first day line traffic control links to each other respectively for one; The described the 1 receives/send out module is connected with first central processing unit is two-way respectively with the one 315 a receipts/module; Described the one 433 receipts/send out module to receive with the 1/module is connected respectively with first a receipts/controller, and described first receives/send out a controller is connected with first central processing unit is two-way; Described mobile unit comprises: the 2 433 receive/send out module and the 2 315 and receive/send out module with second day line traffic control links to each other respectively for one; The described the 2 433 receives/send out module is connected with second central processing unit is two-way respectively with the 2 315 a receipts/module; Described the 2 433 receipts/send out module to receive with the 2 a 315/module is connected respectively with second a receipts/controller, and described second receives/send out a controller is connected with second central processing unit is two-way;
Described first central processing unit also links to each other respectively with keyboard, luminotron and hummer respectively; Described second central processing unit also respectively with topworks in system power-up, sound equipment power up and generator powers up respectively and links to each other; Described second central processing unit also links to each other respectively with vibration transducer, vehicle condition respectively.
The present invention is made up of hand-held remote controller and mobile unit two parts.They have constituted the system of a pair of two-way communication.Hand-held remote controller sends to mobile unit by button and powers up, switches standby and instruction such as start, and grasps the vehicle condition of automobile simultaneously according to sound and luminotron.Mobile unit is then carried out above-mentioned action according to telecommand, and in real time implementation status is issued telepilot.
When automobile was stolen, mobile unit was transmitted messages to telepilot and warned instruction, and is stolen with chimes of doom prompting automobile.
The present invention selects for use 2 points frequently: 433.92MHz, 315MHz
Telepilot principle of the present invention is introduced: telepilot is by antenna sending and receiving controller, and the duplexing receive-transmit system that peripherals such as controller, central processing unit and keyboard, luminotron, hummer are formed is received/sent out to 315MHz transceiver module, 433MHz transceiver module, first.
In order to make radio frequency go into, go out the purpose of a shared antenna, adopted the controller of high-isolation; In order to improve interference free performance, use the some frequency of 315MHz and two GBs of 433MHz.Like this can be when being disturbed, can change point frequently.
Central processing unit can send nearly 10
16Therefore address code can be accomplished the uniqueness of address code.
Mobile unit principle of the present invention:
The telepilot principle of mobile unit is the same also by antenna controller, 315 transceiver modules, 433 transceiver modules, second receipts/send out controller, central processing unit etc. to form, different is that it has execution module, carry out the action that remote command requires, having the state indicating module can gather the present status information of car sends to telepilot, vibration transducer is arranged, when the people stole car, vibration transducer had signal, sent chimes of doom by mobile unit.
Accomplish 10
16A plurality of addresses make the address code uniqueness that becomes.
Adopt the little receiver module of noise figure, thus receiver sensitivity accomplish-120dBm strengthens the distance of communication.
Keyboard is to send instructions such as showing start, query State, shutdown.
Luminotron indication telepilot receives the information of mobile unit.
Hummer is then shown the state of car by the difference of sound.
Tick-represent the start or shutdown command be performed.
Tick. tick. tick---the expression car has been to have started state.
Tick-tick--represent that car starts, just at detected state.
Stealing the car chimes of doom in addition will be to tick--tick--ticking---.
High sensitivity of the present invention receives:
The digital signal optimum taking air ratio increases communication distance greatly, can reach 3 kilometers through actual measurement.
The present invention is microwave 433MHZ, the digital communication of 315MHZ, so link transmission is that open circuit, sighting distance, nothing block, do not consider multi-path influence, precipitum influence, do not consider should meet following computing formula when earth curvature influences:
Pr＝Po-Ltd+Gt-Lo+Gr-Lrd
Lo＝92.4+201g[f(GHZ)*d(km)]
Wherein the present invention of Pr------receiver sensitivity is-120dbm
The present invention of Po------emissive power is 10dbm
Make a start feeder line and joint equal loss the present invention of Ltd-----is 2db
Lrd-----receiving end feeder line and joint equal loss the present invention are 2db
The Gt------antenna gain the present invention that makes a start is-5db
The present invention of Gr------receiving end antenna gain is-3db
Lo------free space loss the present invention is 122db
20Lg(0.4d)＝25.6
Lg0.4d＝1.28
0.4d＝19km
d＝47.5km
Have when considering actual measurement block, the influence of multipath interference, aerial position etc., actual measurement is 3.1 kilometers.
Double frequency is anti-interference:
When adopting the 433MHz point frequently, the mode bit of receiving/sending out in the controller is in high level, hand-held remote controller remains on the frequency of 433.92MHz with communicating by letter of mobile unit, in a single day when interference being arranged, address code can not be decoded, a mode bit of receiving/send out control this moment is an electronegative potential, then this moment, hand-held remote controller remained on the frequency of 315MHz with communicating by letter of mobile unit, therefore 315MHz, when two points of 433MHz have interference frequently, conversion work mutually.
Guarantee the uniqueness of address:
Decoding circuit adopts chip SC2272, because SC2272 has totally 12 of address code A0-A11, adopts 48 of 4 total address wires, gets 40 and forms 10 set of address bits, and every group address is 4, can form 16 states, therefore can have 10
16Address code.Other 8 can be used as data bit.
