The utility model content
The purpose of this utility model is to provide a kind of 20V to 100V Integrated Service Digital Network news transmission circuit, realizes only with a holding wire, just can controlling all electric equipments on whole automobile.
The technical solution of the utility model is as follows:
A kind of 20V to 100V Integrated Service Digital Network news transmission circuit, comprise that outer lead pin, signal modulation transtation mission circuit, signal demodulation receiving circuit, single-chip microcomputer, reset circuit, 20V to 100V turn the 12V Switching Power Supply, 12V turns the 5V voltage stabilizing circuit; Described signal modulation transtation mission circuit, signal demodulation receiving circuit are connected between outer lead pin and single-chip microcomputer; Described reset circuit connects single-chip microcomputer; It is single-chip microcomputer and the power supply of signal demodulation receiving circuit that described 12V turns the 5V voltage stabilizing circuit; It is that signal modulation transtation mission circuit and 12V turn the power supply of 5V voltage stabilizing circuit that described 20V to 100V turns the 12V Switching Power Supply.
Useful technique effect of the present utility model is:
The utility model is only born reception, transmission, control, controlled four major functions with a holding wire.Although share a return line with the battery cathode of this car, this two line of the anode of this car and battery cathode is absolutely necessary, the holding wire of the utility model circuit design only has one thus.The utility model is carried and is handed over the CF signal ripple on direct current supply line, is applicable to 48V, 60V, 72V batteries circuit.
The additional advantage of the utility model provides in embodiment description partly below, and part will become obviously from the following description, or recognize by practice of the present utility model.
The accompanying drawing explanation
Fig. 1 is block diagram of the present utility model.
Fig. 2 is schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
Fig. 1 is block diagram of the present utility model.As shown in Figure 1, the utility model comprises: outer lead pin, signal modulation transtation mission circuit, signal demodulation receiving circuit, single-chip microcomputer, reset circuit, 20V to 100V turn the 12V Switching Power Supply, 12V turns the 5V voltage stabilizing circuit.Signal modulation transtation mission circuit, signal demodulation receiving circuit are connected between outer lead pin and single-chip microcomputer.Reset circuit connects single-chip microcomputer.It is single-chip microcomputer and the power supply of signal demodulation receiving circuit that 12V turns the 5V voltage stabilizing circuit.It is that signal modulation transtation mission circuit and 12V turn the power supply of 5V voltage stabilizing circuit that 20V to 100V turns the 12V Switching Power Supply.
Fig. 2 is schematic diagram of the present utility model.As shown in Figure 2, outer lead pin J1 has 6 terminals totally 3 lead-in wires, and 3 lead-in wires are respectively 20V to 100V(can be for 48V, 60V, 72V etc.), Y-signal line and ground wire.Transformer T1, triode Q1, triode Q2 and peripheral electron element thereof have formed signal modulation transtation mission circuit.Transformer T2, triode Q3 and peripheral electron element thereof have formed signal demodulation receiving circuit.U1(46R01C) be the single-chip microcomputer on terminal node.12V turns 5V Voltage stabilizing module U2(78L05) and the peripheral electron element formed 12V and turned the 5V voltage stabilizing circuit, for giving system power supply.Switching Power Supply U3(LNK304) and the peripheral electron element formed 20V to 100V and turned the 12V Switching Power Supply, can be by the 12V that changes into of the voltage stabilization of 20V to 100V.System reset triode Q4 and peripheral electron element thereof have formed reset circuit.When the control signal that main system sends is arranged on the Y-signal circuit of outer lead pin J1, capacitor C 3 couplings through signal demodulation receiving circuit, transformer T2 amplifies, crystal oscillator Y2 absorbs carrier wave, triode Q3 amplifies 7 pin of delivering to single-chip microcomputer U1 by resistance R 7 again and carries out the system decodes analysis, analysis result is as found it is while controlling the signal of this terminal, just controlled the processing in time at 4 pin of single-chip microcomputer U1 exported treatment states immediately, also the information exchange of slave mode can be crossed to the resistance R 2 of 6 pin of single-chip microcomputer U1 through signal modulation transtation mission circuit in the time of controlled, triode Q2, triode Q1, transformer T1, capacitor C 2 is transmitted back on the control bus of outer lead pin J1.During system reset, 5 pin that triode Q4 delivers to single-chip microcomputer U1 by reset signal are resetted.
Above-described is only preferred implementation of the present utility model, and the utility model is not limited to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite that does not break away from basic conception of the present utility model, within all should thinking and being included in protection range of the present utility model.
