A plurality of normally closed dry reed pipe K1 are in parallel with a plurality of open type dry-reed tube K1 ', draw battery E and import to the power supply of annunciator main frame 201, therefore as long as the switch connection of dry-reed tube is wherein arranged, draw the power supply input just connection of battery E to annunciator main frame 201.
When battery case breaks away from battery case, before the relay J adhesive, the switch in parallel of a plurality of dry-reed tubes and the effect of combination in any, be used to prevent artificially normally closed dry reed pipe K1 is drawn the supply disconnecton of battery E to annunciator main frame 201 with magnet, improved reliability, number is many more, and reliability is high more.
When battery case was put into battery case, the switch of normally closed dry reed pipe K1 dry-reed tube under the effect of the magnetic field of corresponding permanent magnet N1 disconnected.
A plurality of open type dry-reed tube K1 ' are used for when battery case breaks away from battery case, before the relay J adhesive, prevent artificially normally closed dry reed pipe K1 being drawn the supply disconnecton of battery E to annunciator main frame 201 with magnet, when the wrong corresponding open type dry-reed tube of magnet, the switch connection of open type dry-reed tube, number is many more, and reliability is high more.
The open contact of relay J and the switch of dry-reed tube are in parallel, concrete path is connected in the power supply input that is used for annunciator main frame 201, when relay J is in attracting state, the switch of normally closed dry reed pipe K1, open type dry-reed tube K1 ' disconnects arbitrarily, and the power supply input of annunciator main frame 201 remains connection.
Mu balanced circuit 8 is used for power supply E voltage stabilizing is become annunciator main frame 201 required operating voltages.
The set end S of d type flip flop 14 connects capacitor C to power supply E negative pole, when being used for d type flip flop 14 and powering on, under the process of charging effect of capacitor C, the set end S of d type flip flop 14 is " 0 ", and the output Q end set of d type flip flop 14 is " 1 ", the capacitor C charging finishes, and set end S is input as " 1 ".
Diode D is used to prevent battery E reversal connection to annunciator main frame 201, thereby the circuit of protection annunciator main frame 201 is not burnt out.
Battery E is the batteries in the battery of electric vehicle box.
Set end S at d type flip flop 6 is under the one state, and when controller 1 output pulse during to the clock CP end of d type flip flop 6, the Q end is output as " 0 ".
As described in Figure 2, the program function flow process of controller 1 is as follows:
A, system initialization;
B, reading learn button 10, whether be " 1 ", yes, for " 1 ", enter next step, otherwise enter step h if differentiating;
C, detection password acceptor circuit 5, whether have signal input, have the signal input to enter next step, otherwise enter step I if differentiating;
D, with parameter storage 2 in cipher key information relatively, the identical next step that enters, otherwise enter step I;
E, the stolen alarm sound of mute speaker battery case;
F, read switch 9, differentiate whether input is arranged, have input to enter next step, otherwise enter self-loopa;
G, time-delay 5 seconds, the output pulse finishes to the clock input CP end of d type flip flop 6, and after the purpose of time-delay was used to guarantee that relay J discharges, the switch of dry-reed tube was in off-state;
H, enter the cipher key study module, study finishes to enter step b;
I, output alarm signal send the stolen alarm sound of battery case to driving amplifying circuit 3 by loud speaker, change step b.
Using method
With a plurality of normally closed dry reed pipe K1 and a plurality of open type dry-reed tube K1 ' combination in any arrangement mutually, permanent magnet N1 makes it corresponding with normally closed dry reed pipe K1 on the adjustment battery case inwall as required for a, user;
B, learn button 10 is placed the cipher key learn position, make the power connection of alarm host machine, password sends button on the password transmitter 11 by opening, and carries out cipher key study, and study is finished learn button 10 is placed the normal working position;
C, close (cancelling) alarm sound after after closing (cancelling) alarm sound, battery case being put into battery case or battery case being put into battery case, the power supply of annunciator main frame 201 is in when cutting off, antitheft alarm system is on the alert, and is energy-conservation, do not need user's warning of setting up defences;
D, when battery case breaks away from battery case, the power connection of annunciator main frame 201 and alarm sound have only when alarm host machine receives the code signal of password transmitter 11 and just close (cancelling) alarm sound;
E, when the user need take off battery case, send button by opening on the password transmitter 11 when taking off battery case, take out the back up to battery case and decontrol, annunciator main frame 201 will be cancelled alarm sound in the very first time, thus annunciator main frame 201 does not produce alarm sound.
