Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 4, in the utility model embodiment, a kind of telesecurity electric heater control system, comprise controller, ring detecting circuit, imitate pick machine circuit, DTMF decoding circuit and channel control circuit, controller connects ring detecting circuit, imitate pick machine circuit, DTMF decoding circuit and channel control circuit respectively, channel control circuit also connects electric heater, imitate pick machine circuit also connects DTMF decoding circuit and telephone wire respectively, and telephone wire also connects ring detecting circuit and voice warning circuit respectively.
Controller adopts P89LPC932.
Ring detecting circuit adopts stabilivolt, photoelectrical coupler and reverse transistor, and the ringdown of one-period is changed into the square-wave signal of one-period, the INTO sending into controller counts.
Imitate pick machine circuit controls the break-make of transistor by controller, and then the break-make of pilot relay K1 realizes imitate pick machine.
DTMF decoding circuit adopts chip MT8870.
Channel control circuit adopts transistor to come closedown and the unlatching of pilot relay K as on-off circuit, thus realizes the control to passage.
Principle of work of the present utility model is: refer to Fig. 1 ~ 4, when needs are to electric heater Long-distance Control, corresponding fixed line phone number can be dialed, its ring detecting circuit works, after ringing number reaches set point number, start voice warning circuit and send prompt tone by controller, whether inquiry enters electric heater control model, receive calls when there being people or ringing number is less than set point number time, the use of program-controlled telephone is not impacted.Electric heater control model is that to press " O " key no, on-hook is exited, pressing " 1 " key is, dynamo-electric road automatic off-hook of seting out enters state of a control and is input in controller by off hook signal, voice can be started after controller receives off hook signal simultaneously, cue circuit sends prompt tone, and point out operator to input password, the password of operator's input is after DTMF decoding circuit receives, convert binary number to and compared with the password stored in the controller, password can input three times, if three code error, to send after miscue sound and on-hook, if password conforms to, then control channel (button l is selected in voice message, 2 represent 1 respectively, No. 2 passages), after selector channel, press " O " key table and show this road electric heater of shutoff, there is prompt tone " this road electric heater is closed ", press " 1 " key table and show this road electric heater of unlatching, and have voice message " this road electric heater is opened ", press " O " key more then can on-hook to exit.
