Embodiment

Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, herein signal of the present utility model Property embodiment and explanation be used for explaining the utility model, but be not intended as limiting of the present utility model.

Reference picture 1, the utility model discloses a kind of heating sucker rod heating remotely with chain electric power load control module, including Control unit 1, microprocessor 4, communication unit 6, the microprocessor 4 connect control unit 1 and communication unit 4 respectively, described Control unit 1 includes zero cross detection circuit 2 and magnetic protective relay control circuit 3, the zero cross detection circuit 2 and magnetic protection after Electrical apparatus control circuit 3 connects microprocessor 4 respectively, and the communication unit 6 includes CANBUS telecommunication circuits 7 and RS232 communication electricity Road 8, the CANBUS telecommunication circuits 7 and RS232 telecommunication circuits 8 are respectively connecting to microprocessor 4, and the microprocessor 4 also connects AD/DC modules 9 and power down memory 5 are connected to, the CANBUS telecommunication circuits 7 include CANBUS transceiving chips 10 and CANBUS is auxiliary Help circuit 11 and connect the high speed photo coupling 12 of CANBUS transceiving chips.

The utility model is changed by alternating current 220V power taking through AC/DC modules 9, and 220VAC is converted into 12VDC, then through three The stable depressor in end, is down to 5VDC, for needed for this provides power supply using new module by 12VDC.Module of the present utility model Communication interface 6 can connect the wireless module of transparent transmission, such as wireless digital broadcasting station, ZigBee wireless communication modules etc., also may be used To be connected by wired CAN communication, the control command of outside hair repeatedly is received.Module, can be in a week after order is received It will exchange electrically disconnected by touching guard relay in phase or connect chance.Module, using infant industry control microcomputer (single-chip microcomputer), is whole The core of individual load control module, is responsible for coordinating the work of each several part circuit, receives outside order and makes and answers in noon and to outgoing Send command response.8 single-chip microcomputer μ PD78F0881 of the single-chip microcomputer model NEC Corporation that this module is used, there are 32K words inside The internal program memory of section, built-in CAN controller, using 4M clocks, the communication interface 6 that this module is used for RS232 communication interfaces and CAN communication interface, are respectively used to different occasions.232 communication interface main functions are:(1) can be with PC Machine is joined directly together, and parameter setting or debugging are carried out to module.(2) it can be attached with the wireless device of 232 interfaces, module is entered Row control or parameter setting.Because the power supply of this module is directly obtained by power line 220VAC, the utilization of wireless module can Make the problem of this module is flexibly installed sub various occasions and connected up without worry.Due to the advantage of wireless mode, this module will be Most of occasion uses wireless mode.(3) place of radio communication can not be used greatly in some air interferences or do not allow Using the occasion of radio communication, module and PERCOM peripheral communication will be made using the CAN communication interface of module.Magnetic latching relay and its control Circuit processed is the order executing agency of the utility model Shen, and the control to electric load will be completed by touching guard relay.Touch guarantor It is a kind of new type of relay grown up in recent years to hold relay, is also a kind of automatic switch.Relay one is got over other electricity Sample, turn on automatically and cutting action are played to circuit.Except that, the normally closed or normally open for touching guard relay is entirely The effect of permanent-magnet steel is relied on, the conversion of its on off state is completed by the pulse electrical signal triggering of one fixed width.By In magnetic latching relay, its contact opening and closing state is kept as the impact force produced by permanent-magnet steel.When touching for relay Point needs are opened or during conjunction state (when switching on or off load), it is only necessary to just (anti-) DC pulse voltage excitation coil, relay What device was just completed in moment opens the State Transferring with closing.At this moment power attenuation is generally less than 1W.Guarantor is touched in the utility model Shen It is 60A to hold the maximum contact change-over electric current of relay, namely the maximum controllable device current of this module is 60A；Make to touch holding The pulse width of relay adhesive is 20ms, and release time is 15ms.Magnetic latching relay controls circuit 3 as shown in figure 3, in circle The excitation coil of contact relay is distinguished with Control end 2 in Control end 1；Control 101 is connected single respectively with control 102 10 mouthfuls of piece machine.When 101 export high level, during 102 output low level, triode 01,04 is led in saturation can state, 02,03 In cut-off state, now, the voltage of Control end 1 is 12V, and Control end 2 is GND, after 100ms, 101 outputs Low level, now 01,02,03,04 is in cut-off state, and the voltage being now carried on coil is released, and thus, generates one The individual pulse that can make to touch guard relay action.100ms pulse width why is used, is to ensure its reliable adhesive Or disconnect.Assuming that exporting the pulses of 100ms generations from 101 for if positive pulse, then, 102 output 100ms pulse will be Touch guard relay and produce a negative pulse.

The technical scheme disclosed in the utility model embodiment is described in detail above, it is used herein specifically Embodiment is set forth to the principle and embodiment of the utility model embodiment, and the explanation of above example is only applicable to Help understands the principle of the utility model embodiment；It is real according to the utility model simultaneously for those of ordinary skill in the art Example is applied, be will change in embodiment and application, in summary, this specification content should not be understood For to limitation of the present utility model.
