Description
Technical field
The utility model relates to a kind of device of checking oneself, and relates in particular to a kind of generator set controller and checks oneself device.
Background technology
In the debugging of being transported to electric system of host computer to genset monitoring and PLC control; and the genset occasion of separating with gen-set control system; the operational process that needs simulation generator set; but starter-generator group controller only; because controller can't read generating voltage value and oil pressure value; the controller shutdown of can reporting to the police; causing can't communication with host computer; whether the design concept that also can't test the generator set control circuit is correct; whether the wiring circuit is normal, whether reaches expectation function.Based on above-mentioned background, proposed a kind of gen-set control system and checked oneself circuit.
Summary of the invention
The purpose of this utility model is to provide a kind of generator set controller to check oneself device; process by generator set control line simulation unit operation; solve in host computer and the control system communication debugging and repeat the start and stop problem, and can be used as that PLC controls be transported to the electric system function debugging.
The utility model is to realize like this, it comprises oil pressure potentiometer, generator set controller, fuel tap relay, voltage detecting port, analog input port, it is characterized in that civil power and oil pressure potentiometer are received respectively the contact of normally opened contact of the scale-of-two output point fuel tap relay of generator set controller, voltage detecting port and the analog input port of generator set controller guided to respectively in the another one contact.
After generator set controller sends startup command, scale-of-two output point fuel tap relay closes is often opened the auxiliary contact closure, and civil power and oil pressure potentiometer are linked into the corresponding detection port of generator set controller, controller thinks that genset starts successfully, is operated in running status.After controller sent halt command, scale-of-two output point fuel tap relay disconnected, and often drove auxiliary contact and disconnected, and the detection port of generator set controller can't detect civil power and oil pressure potentiometer, and controller thinks that genset shuts down successfully, is operated in the state of awaiting your instructions.
Press controller and start button, after the startup, the access of the voltage detecting port of generator set controller and rated voltage size, frequency, the civil power that line system is consistent access potentiometer at the analog input port and simulate oil pressure.Specific practice is that the number of teeth of at first revising generator set controller is revised as by frequency meter, a contact of then civil power and oil pressure potentiometer being received respectively the normally opened contact of scale-of-two output point fuel tap relay, voltage detecting port and the analog input port of generator set controller guided to respectively in the another one contact.After controller sends startup command, scale-of-two output point fuel tap relay closes is often opened the auxiliary contact closure, and civil power and oil pressure potentiometer are linked into the corresponding detection port of generator set controller, controller thinks that genset starts successfully, is operated in running status.After controller sent halt command, scale-of-two output point fuel tap relay disconnected, and often drove auxiliary contact and disconnected, and the detection port of generator set controller can't detect civil power and oil pressure potentiometer, and controller thinks that genset shuts down successfully, is operated in the state of awaiting your instructions.
If the unit operation pattern is directly received scale-of-two input point GCB combined floodgate feedback with the output of scale-of-two output point GCB on/off switch, can simulate the on/off switch process of unit.
For the control system that the parallel operation requirement is arranged, on the basis of above-mentioned circuit, need to increase air switch.At first scale-of-two output point GCB closing relay is often opened the closing coil that auxiliary contact are received air switch, scale-of-two output point GCB separating brake relay normally open auxiliary contact are received the switching winding of air switch, air switch is often left auxiliary contact receive scale-of-two input point GCB combined floodgate feedback.Secondly, access homology voltage in operation circuit.After starting a generator set controller and closing a floodgate, start next generator set controller, press the combined floodgate button after starting successfully, two controllers have same voltage, same frequency, same-phase and reach the parallel operation requirement, can realize parallel function.
The utility model has the advantages that: do not need to access unit, just can simulate unit running process by gen-set control system, for checking whether the line design principle is correct, time-delay is controlled, whether the wiring circuit is normal, whether expectation function is realized, especially significant in the debugging of host computer and the communication of generator set control circuit.Circuit is simple and reliable, implements easily, and is with low cost.
Description of drawings
Fig. 1 is the utility model separate unit connection circuit schematic diagram.
In the drawings, 1, oil pressure potentiometer 2, generator set controller 3, fuel tap relay 4, voltage detecting port 5, analog input port.
Embodiment
As shown in Figure 1, the utility model is to realize like this, it comprises oil pressure potentiometer 1, generator set controller 2, fuel tap relay 3, voltage detecting port 4, analog input port 5, civil power and oil pressure potentiometer 1 are received respectively the contact of normally opened contact of the scale-of-two output point fuel tap relay 3 of generator set controller 2, voltage detecting port 4 and the analog input port 5 of generator set controller 2 guided to respectively in the another one contact.
After generator set controller sends startup command, startup, fuel tap output, fuel tap relay 3 closures, the oil pressure potentiometer 1 access oil pressure detection port of simulation fuel injection pressure signal, (the fuel tap relay coil is connected with fuel tap relay normally open auxiliary contact fuel tap relay 3 closures simultaneously, fuel tap relay 3 electric after, the fuel tap relay closes), the three-phase and four-line line voltage adds the generating voltage detection port.Gen-set control system has detected generating voltage and oil pressure, thinks the unit starting success to be operated in state in the unit operation.
Gen-set control system sends when closing a floodgate order, and gen-set control system has received the combined floodgate feedback signal, thinks that air switch closes a floodgate successfully, is operated in "on" position of unit.When gen-set control system sent the separating brake order, the combined floodgate feedback signal disappeared, and gen-set control system thinks that the air switch separating brake is successful, is operated in state in the unit operation.
After gen-set control system sent halt command, fuel tap stopped output, and the fuel tap relay disconnects, and the potentiometer of simulation fuel injection pressure signal disconnects from the oil pressure detection port, and the fuel tap relay disconnects simultaneously, and the three-phase and four-line line voltage disconnects from the generating voltage detection port.Gen-set control system can't detect generating voltage and oil pressure, thinks compressor emergency shutdown success, is operated in the unit middle state of awaiting your instructions.
