Be described in detail the utility model below in conjunction with accompanying drawing.
The utility model door magnetic is made up of door state sensing mechanism and door status information trigger mechanism, and information sensing mechanism is that permanent magnet and magnetic induction part are synthetic, and the two is contained in the close positions of door and doorframe, and magnetic induction part can be a tongue tube.Door status information trigger mechanism is to be the main electronic circuit that constitutes by coding integrated package, radio transmission module, tongue tube output out gate status information V
0(state 0, open circuit) and V
1(state 1, conducting) links to each other with coding integrated package, radio transmission module as the K switch of power supply E.
The coding integrated package can be VD5026 or MC145026, and the radio transmission module can be TDC1808 or TH6502 or VS3050, also can be that discrete component combines.
Also have electronic switching circuit in the door status information trigger mechanism, electronic switching circuit is by tongue tube output V.And V
1As the power switch K of electronic switching circuit cut-out, conducting, the electronic switching circuit output links to each other with the coding integrated package.
Door state radiating circuit shown in Figure 1 is by radio transmission module (1) TDC1808.Coding integrated package (2) VD5026 or MC145026 and electronic switching circuit (3) constitute.The power supply of radio transmission module and coding integrated circuit is controlled by electronic switching circuit.Electronic switching circuit output is set at a pulse signal about 0.5～1.5 second.Operating principle is: door is in the state (state 0) of pass, and the electronic switching circuit output voltage is 0, and when door during from state 1 that closed condition 0 becomes out, because the variation of magnetic field of magnets, tongue tube is exported from V
0Become V
1At this moment electronic switching circuit will be exported a high level pulse signal that is set at about 0.5～1.5 second, radio transmitter circuit and coding integrated package since the electric time that will work about 0.5～1.5 second, and the signal that door is opened launched by the radio transmission module.The effect of coding integrated package is to provide a geocoding, makes alarm be confirmed to be which door alarm, and model is VD5026 or MC145026, trigger control end 14 pin ground connection wherein, and 17 pin link to each other with remote-control transmitting module input 2 pin.
The operating principle of door status information radiating circuit shown in Figure 2 is: trigger control end 14 pin of coding integrated package link to each other with electronic switching circuit, and the electronic switching circuit output wave is a square wave.Because radio transmission module and coding integrated package are in holding state (not transmitting), quiescent current is minimum.Though therefore entire circuit is in holding state, power consumption is still very low.Have only when coding integrated package 14 pin are low level, output 17 pin just have modulation signal output, radio transmitter circuit work, thereby alarm signal is sent, the operating principle of electronic switching circuit is identical with last example, just output waveform is just in time opposite, is output as a pulses low about 0.5～1.5 second.
Electronic switching circuit can be by resistance R, capacitor C and FET BG
1The combinational circuit that constitutes, BG
1Grid G links to each other with R, and drain D links to each other with the R other end and K switch one end, another termination power cathode (Fig. 3) of capacitor C.BG
1Be FET, when door was in closed condition, because the magnet effect, tongue tube K was in off-state as shown in the figure.When door is opened, tongue tube output V
