Abstract
The invention discloses a safe energy-saving controller, and the controller comprises a CPU. A GP1 end of the CPU is connected with an optical coupling input circuit, and a GP4 end of the CPU is connected with an optical coupling output circuit. A VCC end of the CPU is connected with a power supply, and an input end of the optical coupling input circuit is connected with a current sensor which is connected with the power supply. An output end of the optical coupling output circuit is connected to a driving circuit of a relay. The invention has the following technical effects that a rectification cabinet stops output when a locomotive current collector leaves from an aerial line; the aerial line does not have high-voltage current so as to guarantee the personal safety; a power line of a current sensor supplies a signal voltage less than 24V to the aerial line; and a main transformer of the rectification cabinet stops working and enters into an energy-saving state. When the locomotive current collector contacts with the aerial line, the rectification cabinet instantly carries out power supply.
Description
Technical field
The present invention relates to a kind of safe energy-saving controller, for mine trolley locomotive rectifier cabinet, also can be applicable to other field and be used as automatically to control.
Background technology
Existing mining general electric locomotive stringing rectifier cabinet adopts two kinds of working methods.Mode one, manual mode: stringing is powered always after manually starting, after over current fault occurs, rectifier cabinet quits work, and stringing has a power failure.Automated manner: stringing is powered always after manually starting, after over current fault occurs, rectifier cabinet quits work and starts timing simultaneously, and timing reaches stringing automatic power after setting value.
The shortcoming of prior art: when stringing after startup is always with high-tension electricity, when pedestrian is through existing potential safety hazard.When electric locomotive quits work, stringing is also always with high-tension electricity, and rectifier cabinet is in no-load running always.
Summary of the invention
The object of this invention is to provide a kind of mine trolley locomotive safe energy-saving controller.
Technical scheme of the present invention is, a kind of safe energy-saving controller, comprises CPU, at the GP1 termination optocoupler input circuit of CPU, the GP4 termination optocoupler output circuit of CPU, the VCC termination power of CPU, the input termination current sensor of optocoupler input circuit, is connected to power supply at current sensor; Be connected on the driving circuit of relay at the output terminal of optocoupler output circuit.
The present invention has following technique effect, after electric locomotive current collector leaves stringing, rectifier cabinet stops exporting, stringing is not with high-tension electricity to guarantee personal safety, the power circuit of current sense is to stringing signal voltage lower than 24V simultaneously, and rectifier cabinet main-transformer quits work and enters power save mode simultaneously.When after electric locomotive current collector contact stringing, rectifier cabinet is power transmission immediately.
Accompanying drawing explanation
Fig. 1 is circuit block diagram of the present invention.
Embodiment
As shown in Figure 1, a kind of safe energy-saving controller, comprise CPU, CPU model is IC16F269, at the GP1 termination optocoupler input circuit of CPU, the GP4 termination optocoupler output circuit of CPU, the VCC termination power of CPU, the input termination current sensor of optocoupler input circuit, the input end of current sensor is connected on stringing; Power supply is connected at current sensor; Be connected on the driving circuit of relay at the output terminal of optocoupler output circuit, the control end of relay is connected on the main contactor of rectifier cabinet, and 360V power supply connects rectifier cabinet, and rectifier cabinet current output terminal connects stringing.
Principle of work of the present invention:
When device power, CPU detects the duty of rectifier cabinet by external impressed current sensor in real time and sends into CPU by optocoupler input circuit.When having detected that stringing has current collector to contact, CPU has sent enabling signal and has promoted relay drive circuit to optocoupler output circuit and close rectifier cabinet main contactor main circuit and start working.When current collector on stringing disconnects, CPU time delay sends stop signal and promotes relay drive circuit disconnection rectifier cabinet main contactor to optocoupler output circuit.Now pole line is not with high-tension electricity, and the power circuit of current sense is to stringing signal voltage lower than 24V simultaneously, and master connects device disconnection main-transformer and enters energy saver mode simultaneously.
