Embodiment
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
With reference to Fig. 1, the present invention is a kind of controls the control device that generator and civil power power to the load, comprise control module 10, mains electricity input end mouth 20, first detection module 30, the first switches set 40, generator 50, second switch group 60, the second detection module 70, storage battery 80, electric weight detection module 90, environment measuring module 100, the below is elaborated to each part:
Mains electricity input end mouth 20 be utility grid to a wire-pressed terminal of load input AC electricity, it can connect some loads.
Described first detection module 20 1 ends connect the first switches set 30 outputs, other end link control module 10, and first detection module is sent to control module 10 with the city's electric parameter information that detects, and control module 10 is single-chip microcomputer or the control devices such as PLC or DSP.First detection module 20 is comprised of voltage detecting circuit, current detection circuit and frequency detection circuit, respectively the parameter information of voltage, electric current and the frequency of civil power is detected by these testing circuits, make control module know in time the concrete condition of civil power, according to these situations so that make the adjustment of power supply.
The first switches set 40 is connected with mains electricity input end mouth 20, the first switches set 40 also is connected with control module 10, the first switches set 40 is comprised of a plurality of auxiliary relays, the coil of these auxiliary relays is connected with the output of control module, the switch contacts of these auxiliary relays connects between load and mains electricity input end mouth, and therefore the first controlled module controls of switches set disconnects the switch that wherein receives order.In the first switches set 40, a plurality of switches are arranged, its quantity is more than or equal to the quantity of load, in the first switches set 40, each switch all is numbered, the mode of concrete numbering is that the numbering of connected load is identical, as the First load be numbered 1, the numbering that connects the switch of this load is also 1, in the control program of control module, by the numbering to load and switch, so that being made to disconnect ground, each switch controls.Yet, when certain load need to move, can only accordingly the switch that connects this load be carried out manual closing, i.e. the control of the closed uncontrolled module 10 of each switch in the first switches set 40.
The second detection module 70 is connected with control module 40, and the second detection module detects the whether in running order of each load, and testing result is delivered to control module.Whether the second detection module 70 is mainly to have operating current to flow in each load be used to knowing, if there is electric current to flow into, illustrates that load begins or in running order.Because every load all has numbering, therefore, detect each load by the second detection module 70, numbering to each load is identified, and send these information to control module, control module just can know that those loads are in running status, so that prepare for the concrete switch in subsequent control the first switches set 40.
One end of generator 50 is connected with control module 40, control module is according to the quantity of parameter and the operating load of current civil power, control generator and open or close, make generator separately to each load supplying, perhaps make civil power and generator respectively to the load supplying of correspondence.Namely when the overtension of civil power or too lowly all will control the first switches set by control module and disconnect, make the disconnection that is connected of load and civil power, thereby avoid civil power in the unstable state situation to load shock, damage load, and by the work of control module starter-generator, proceed power supply by generator to the load that is cut off mains supply.And when the load number that puts into operation is too much, detect by the operation quantity of the second detection module to load, after control module obtains this situation, numbering by load is cut off the load that a part connects civil power, can alleviate the burden of utility grid like this, demand to utility grid when avoiding load too much is large, the situation that the utility grid paralysis occurs, simultaneously by the work of control module starter-generator, powered to the load that is cut off mains supply by generator, with the operation demand of proof load.
Environment measuring module 100 is connected with control module, environment measuring module 100 after ambient temperature surpasses set point, shows that some serious situations can appear in surrounding environment for detection of the temperature of surrounding environment, for example fire, at this moment control the first switches set and second switch group and disconnect.
With reference to Fig. 2, the intelligence control method of control generator powered of the present invention comprises the following steps:
Step S1, the switch in manual closing the first switches set make the loaded work piece of corresponding energising, and the numbering of the load of the second detection module under will be in working order is sent to control module, and control module records the numbering of these operating loads;
Step S2, first detection module detects the parameter information of civil power;
Step S3, control module judges the parameter value of information of civil power, judges that namely city's electric parameter value of information is whether in the scope that arranges;
Step S31, if the determination result is NO for step S3, control module is sent the instruction of starter-generator work, and disconnects switch closed in the first switches set, send simultaneously the instruction that makes switch closure in the second switch group, power to the load that disconnects civil power by generator.
Step S4 is if judgment result is that of step S3 is that control module further judge that according to the load of obtaining numbering the quantity of load running is whether in the scope of setting;
Step S5, if the determination result is NO for step S4, the control module starter-generator is worked, and disconnects a part of switch in the first switches set, the switch of closed second switch group, power to the load that disconnects civil power by generator simultaneously.
Step S6 is if judgment result is that of step S4 is that control module is by the detection signal of electric weight detection module to storage battery, whether the electric weight that judges storage battery is sufficient, if the determination result is NO, the control module starter-generator charges to storage battery, if judgment result is that to be, return to step S2.
Identical in the control procedure of method of the present invention and effect and aforementioned intelligent control device do not given unnecessary details at this.
