Referring to fig. 1 and 9, the power-on unit 200 includes a dc power source V1, a dc power source V2, a diode D1, and an electronic switch K1, wherein the negative electrode of the dc power source V1 and the negative electrode of the dc power source V2 are commonly connected in parallel to the negative electrode conductive unit 203 for negative electrode output, the voltage of the dc power source V1 is greater than that of the dc power source V2, one end of the electronic switch K1 is connected to the positive electrode of the dc power source V1, the other end of the electronic switch K1 and the negative electrode of the diode D1 are commonly connected in parallel to the positive electrode conductive unit 202 for positive electrode output, and the positive electrode of the diode D1 is connected to the positive electrode of the dc power source V2. The power supply device comprises two power supplies, namely a direct current power supply V1 and a direct current power supply V2, wherein the voltage is compared with the voltage of the direct current power supply V1, the direct current power supply V2 is the direct current power supply V1, the cathodes of the direct current power supply V1 and the direct current power supply V2 are connected together to form an output power supply cathode, and the positive electrode of the direct current power supply V1 is output to the positive electrode of the power supply through an electronic switch K1.

Referring to fig. 9, in the present embodiment, the communication signal is a series of binary signals, and controls the electronic switch K1, and the 0 state in the communication signal corresponds to the opening of the electronic switch K1; the 1 state corresponds to the electronic switch K1 being closed. The workflow of the above power supply device includes the following: 1. as can be seen from fig. 6, at any time, there is always a voltage at the positive electrode of the power supply at the input terminal. When the electronic switch K1 is turned on, since the dc power V1> is the dc power V2, the diode D1 is turned off in reverse bias, and the output voltage=v1; when the electronic switch K1 is turned off, the diode D1 immediately forward biases, and the voltage drop of the diode D1 is ignored, and at this time, the output voltage=v2; because the electronic switch K1 is controlled by the communication signal source, when there is communication, the communication signal is modulated at the positive electrode of the output power source to form a communication signal, the 0-state control electronic switch K1 is opened, so that the corresponding output direct current power source V2 is realized, and the 1-state control electronic switch K1 is closed, so that the corresponding output direct current power source V1 is realized. And because the signal is a power supply, the carrying capacity is high. The direct current power supply V1 and the direct current power supply V2 correspond to the maximum value and the minimum value of the allowable fluctuation range of the power supply voltage of the jacquard guide bar so as to ensure the power supply of the jacquard guide bar, the 0 state of each point working waveform communication signal of the power supply device is modulated into V2, the 1 state is modulated into V1, and the power supply with the voltage range of V2-V1 is realized while the transmission of the communication signal is completed.

Referring to fig. 9, the electronic switch K includes a capacitor C1, a capacitor C2, a capacitor C3, a capacitor C4, a transistor Q2, a transistor Q3, a transistor Q4, a transistor Q5, a MOS transistor Q1, a resistor R2, a resistor R3, a resistor R4, a zener diode ZD1, and a diode D2; one side of the capacitor C1, one side of the capacitor C2 and one side of the capacitor C3 are connected with the ground in parallel, and the other side of the capacitor C3 is connected with the anode of the direct current power supply V1 in parallel; the cathode of the zener diode ZD1, one end of the resistor R2, the emitter of the triode Q2 and the source of the MOS tube Q1 are connected in parallel with the anode of the direct current power supply V1; the anode of the zener diode ZD1, the other end of the resistor R2, one end of the resistor R3 and the base electrode of the triode Q4 are connected in parallel with the base electrode of the triode Q3; the emitter of the triode Q3, the emitter of the triode Q4 and the collector of the triode Q2 are connected in parallel with the grid electrode of the MOS tube Q1; one end of the resistor R1 is connected with the collector electrode of the triode Q3, and the other end of the resistor R1 is connected with the base electrode of the triode Q2; the other end of the resistor R3 is connected with the collector electrode of the triode Q5; the collector of the triode Q4, the emitter of the triode Q5 and the anode of the diode D2 are connected in parallel to the ground; one end of the resistor R4, one side of the capacitor C4 and the cathode of the diode D2 are connected in parallel with the base electrode of the triode Q5; the other end of the resistor R4 and the other side of the capacitor C4 are connected in parallel with the input end of the communication signal source; the drain electrode of the MOS tube Q1 and the cathode electrode of the diode D1 are connected in parallel with the positive input end of the jacquard comb.

Referring to fig. 9, the MOS transistor Q1 is a P-channel MOS transistor, the transistors Q2 and Q4 are PNP transistors, and the transistors Q5 and Q3 are NPN transistors.

Referring to fig. 9, the operating principle of the above circuit includes the following: 1. the capacitor C1, the capacitor C2 and the capacitor C3 form a power supply filter circuit. 2. The INPUT is a communication signal INPUT end, the driving circuit is composed of a triode Q2, a triode Q3, a triode Q4, a triode Q5, a resistor R1, a resistor R3, a resistor R4, a capacitor C4 and a diode D2, and the clamping circuit is composed of a resistor R2 and a zener diode ZD 1. The MOS transistor Q1 is 1P channel MOS, and is used as an analog switch.

The working process of the circuit comprises the following steps:

referring to fig. 9, assume that at the start, the INPUT level of INPUT is 0 and dc power V1> dc power V2. The transistor Q5 is turned off, and the diode D1 is reversely biased, so that the MOS transistor Q1 is turned off when the potential at point a=v1 and the level at point B ignore the forward voltage drop of the base of the transistor Q3, and the MOS transistor Q1 is a P-channel MOS.

Referring to fig. 9, when an INPUT has a signal INPUT, i.e. the level is 1, the signal is injected into the base of the transistor Q5 through the capacitor C4, and since there is no voltage on the capacitor C4 at the beginning, which is equivalent to a short circuit, a relatively large driving current is provided to the base of the transistor Q5 in a short time, the transistor Q5 is turned on rapidly, and after the capacitor C4 is charged, the resistor R4 continues to provide the current. The capacitor C4 is used to accelerate the conduction of the transistor Q5. The resistor R3 is a current limiting resistor, the resistor R2 is a bleeder resistor, the zener diode ZD1 is a clamping diode, and the zener diode ZD1 exists, so that the voltage between the source electrode and the grid electrode of the MOS tube Q1 is constant, namely the driving voltage is constant, and the MOS tube Q1 is prevented from being damaged due to the fact that the grid electrode of the MOS tube Q1 breaks down when the voltage of the direct current power supply V1 is higher than the voltage withstand voltage of the grid electrode of the MOS tube Q1.

Referring to fig. 9, after the transistor Q5 is turned on, the voltage=vzd1 between the source and the gate of the MOS transistor Q1, so the MOS transistor Q1 is turned on. The triode Q4 has the function of releasing the electric charge of the grid electrode of the MOS tube Q1 in an accelerating way, and the MOS tube Q1 is conducted in an accelerating way. Therefore, when input=1, the MOS transistor Q1 is turned on, and since the dc power V1> is the dc power V2, the diode D1 is reversely biased, so v_out=v1.

Referring to fig. 9, when INPUT is changed from 1 to 0, the charge stored in the capacitor C4 is released through the diode D2, and a reverse bias voltage is formed between the emitter and the base of the transistor Q5, so that the transistor Q5 is turned off rapidly, which is equivalent to an open circuit, and the potential at point a rises rapidly. The resistor R2 has the function of providing a bleeder circuit for the capacitance between the source and the gate of the MOS transistor Q1, and preventing the MOS transistor Q1 from being in a conducting state all the time due to the clamping effect of the zener diode ZD 1. When the potential at the point a rises to approach the dc power V1, the MOS transistor Q1 is turned off and the diode D1 is forward biased, so v_out=v2. From the above analysis, it can be seen that the v_out output voltage is controlled by the INPUT level, input=0, v_out=v2; input=1, v_out=v1.

Other structures are similar to those of the first embodiment and will not be described again.
