Description
The utility model relates to a kind of anti-money alarm.
The alarm of Xiao Shouing is all single group Electronic Control monitoring alarm in the market, its structure is made up of probe and control warning two parts, the signal that sensor is experienced is transferred to the control circuit of alarm by private cable, realization sound, light, electric alarm, the advantage of this kind alarm: simple in structure, make easily, its function can realize the purpose of monitoring anti-theft, but being the signal transmission, its weak point needs private cable, there is frequent wrong report phenomenon to take place, function limitation, multi-point monitoring is reported to the police and is had any problem.
For solving the deficiency of above alarm, the purpose of this utility model provides the comprehensive microwave burglar alarm of a kind of carrier system, the power lead that utilizes the place to have is done the signal transmission, but multi-point monitoring, adopt two probe balance input modes, effectively reach the multiple spot warning, connected simply the purpose of not reporting by mistake.
Structural design of the present utility model is achieved in that the comprehensive microwave burglar alarm of carrier system is made up of post a letter part, the part of receive reporting to the police and intermediate conveyor power lead three parts of detection.Wherein survey and post a letter the part front portion by two probes, middle is that signal amplifier and rear portion are that carrier signal controller three partial circuits connect to form, probe also can be one or more, probe is made of telescopic antenna and the base that circuit is housed, two Technitrons of sensor electrical route are formed, wherein a Technitron is connected in series with telefault, antenna is introduced by collector, telefault joins by resistance R and power supply+12V, simultaneously by capacitor-coupled to the second a Technitron base stage, by the output of triode collector, this signal end is drawn by plug together with power supply and ground wire after amplifying.(as shown in Figure 7) probe signal amplifies through three utmost points, and previous stage is balance input, and second very amplitude control is adjustable, and the 3rd very positive and negative input through the output of diode negative sense, directly connects the controlled encoder input end; Another road probe, connect voltage amplification, be connected to the controlled encoder input end simultaneously through switch, be connected with the oscillator of forming by two phase inverters after the switch, scrambler output and oscillator output are connected on the AND gate simultaneously, AND gate output connects triode amplifier, scrambler output is after triode amplifies, be connected to the former end of output transformer simultaneously through photoelectrical coupler and triode, secondary end is connected on the power supply through capacitance, as the output of transducing signal.
Receiving warning part front is the signal automatic control circuit, on power lead, be connected to the inductive coupling of stopping direct current, by and connect the bilateral diode amplitude limit, form attenuator circuit through field effect transistor, attenuator circuit output one is to be connected to the feedback circuit of being made up of amplifier and diode ﹠ transistor, amplify through diode ﹠ transistor again simultaneously and connect scrambler, the output of scrambler is joined with warning circuit " 555 " circuit block through the diode ﹠ transistor amplification, realize " sound " " light " warning, the height of scrambler output Gao Ping, the work of decision warning circuit with stop.Detection is posted a letter and is realized the working signal path of alarm between part and the reception warning partly by the coupled signal between the power supply power line, and popping one's head in posts a letter partly partly can put any two place realization monitoring, alarmings in the same electric power network with receiving to report to the police.
Detailed structure of the present utility model has following examples and accompanying drawing to provide.
