Abstract
The utility model relates to a power supply controller which is connected with a control host, wherein the control host is provided with a weak relay port. The power supply controller comprises an input pin, a driving circuit and a relay, wherein one end of the input pin is connected with the weak relay port of the control host, the other end is connected with the driving circuit through a jumper, and the driving circuit is connected with the relay. Compared with the prior art, the power supply controller provided by the utility model has the advantages of simple structure, low cost and the like.
Description
Technical field
The utility model relates to a kind of control circuit, especially relates to a kind of power-supply controller of electric.
Background technology
In central control system, manage some switching values with middle control host computer control power-supply controller of electric, the power-supply controller of electric prime is by CPU-integrated circuit and host communication, and the back level is by the relay control switch amount, and internal circuit adopts the mode flow process of CPU-control circuit-relay.
In actual use, when integrated circuit damages or communicating circuit when fault is arranged, entire equipment all can't be worked.Exist in the reality a variety of causes cause input pin can't and host communication, the relay of output pin just can't operate as normal, therefore need do improvement to circuit under case of emergency, guarantees the operate as normal of entire equipment.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of power-supply controller of electric simple in structure, with low cost for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of power-supply controller of electric, be connected with main control system, described main control system is provided with weak relay mouth, described power-supply controller of electric comprises input pin, driving circuit and relay, described input pin one end is connected with the weak relay mouth of main control system, the other end is connected with driving circuit by wire jumper, and described driving circuit is connected with relay.
Described wire jumper is provided with 8.
Also be provided with pull-up resistor in the described power-supply controller of electric, described pull-up resistor is connected between input pin and the wire jumper.
Compared with prior art, the utlity model has following advantage:
1, simple in structure, do not need circuit is done too much improvement, only need to connect 8 wire jumpers and just can finish;
2, low price, not needing increases any circuit or electronic component, with low cost;
3, the utility model has changed the control mode of main control system to power-supply controller of electric, even certain damage is arranged in power controller circuit, power-supply controller of electric is resumed work.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of power-supply controller of electric, be connected with main control system, described main control system is provided with weak relay mouth, described power-supply controller of electric comprises input pin IN, driving circuit ULN2003A and relay, described input pin IN one end is connected with the weak relay mouth of main control system, and the other end is connected with driving circuit ULN2003A by wire jumper L, and described driving circuit ULN2003A is connected with relay.Described wire jumper L is provided with 8.Also be provided with pull-up resistor RP1 in the described power-supply controller of electric, described pull-up resistor is connected between input pin IN and the wire jumper L.
8 tunnel weak relay mouths of input pin IN and main control system link to each other, and when weak relay mouth is closed, are equivalent to the input pin IN short circuit with equipment, give low level of driving circuit ULN2003A input pin, make the actuating of relay.
Present embodiment changes the integrated circuit of power-supply controller of electric into 8 wire jumpers, has changed the control mode of main control system to power-supply controller of electric, even certain damage is arranged in circuitry, equipment is resumed work.
