Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, or can be instructed from practice of the present utility model.Target of the present utility model and other advantages can be realized by structure specifically noted in specification below or accompanying drawing and be obtained.
Accompanying drawing explanation
Fig. 1 is structured flowchart of the present utility model;
Fig. 2 is the power supply circuits schematic diagram of display screen of the present utility model;
Fig. 3 is the interface circuit schematic diagram of the utility model display screen.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 1; the utility model comprises controller, alternating current quantity sampling module, relay output module, display screen, EEPROM memory module, alarm and protection module, keyboard input module, switching input module and Upper machine communication module, and alternating current quantity sampling module, relay output module, display screen, EEPROM memory module, alarm and protection module, keyboard input module, switching input module are connected with controller respectively with Upper machine communication module.The interface of Upper machine communication module adopts RS485 interface or USB interface.
Controller adopts 32 ARM single-chip microcomputers, and hardware integration degree is high, reliable.What in input key system, button adopted is film touch key, easy and simple to handle.Display screen have employed Autoluminescence vacuum fluorescence graphic display (VFD), can show the various information in generator set running, comprise fault message, operation and status information etc.Alarm and protection module can realize alarm and protection function, when there is overheat condition in oil-fired power generating unit, and acoustooptic alarm.
As shown in Figure 2, the operating voltage of VFD display screen is+5V, is its power supply by an independent road+5V power supply ,+the 5.0V_VFD namely in interface circuit figure.Independent power supply, separates with the power supply of whole circuit middle controller and other circuitry the mutual interference just avoided between different electrical power.Anti-lightning strike TVS pipe D2 has been accessed between the positive pole B+ of external dc power DC INPUT and negative pole B-, after anti-reverse diode D1, connect negative tempperature coefficient thermistor RT1, RT1 resistance value varies with temperature and changes, and temperature raises, resistance diminishes, for surge current suppression; Electric capacity C1, C2 play current limliting step-down in whole circuit; Through common mode choke LC1 filtering common mode undesired signal, then through C3, C4 filtering, enter DC-DC DC-DC module VIN input end, after resistance R1 current limliting, enter DC-DC module ON/OFF input end; That DC-DC module adopts is chip MAX5035, and it is a efficient, high pressure, buck mode DC-DC converter, has under-voltage locking, Cycle by Cycle current limit, pattern of having the hiccups output short circuit protection and Thermal shutdown function.Electric capacity C5, C6 are normally worked by discharge and recharge effect DC-DC module; LX end is the output terminal of DC-DC module, and voltage-stabiliser tube DZ1 pressure limiting, exports after inductance L 1, C7, C8 filtering.In figure, R2, R3 provide dividing potential drop to feed back for DC-DC module.
As shown in Figure 3, this interface circuit is a dual-purpose interface circuit, when have independent power supply+5.0V_VFD be VFD display screen power time, resistance R4, R5, R20 not welding component, disconnects with+5.0V power supply, is powered by independent power supply+5.0V_VFD; When do not have independent power supply+5.0V_VFD be VFD display screen power time, resistance R4, R5, R20 weld 0 Ω resistance, by+5.0V Power supply.The reading and writing data bus of the port connection control devices such as RS, RW, CS1, CS2, DB0 of VFD, the I/O port of LCD_BL connection control device, the low and high level control VFD backlight that the controller passed through exports, when controller exports high level, triode Q1 conducting, VFD backlight is bright, when controller output low level, triode Q1 ends, and VFD backlight is gone out.Resistance R6 to R19 is pull-up resistor, and connected port is drawn high as+5.0V, and doing like this is because the power supply of controller is for+3.3V, draws high rear controller and VFD and reads and writes level and just have matched.
The utility model have employed the electronic parts and components of Autoluminescence vacuum fluorescence graphic display (VFD) and resistance to extreme high/low temperature, can be suitable for the working environment of various complexity, can reliably working in extreme temperature conditions.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the field have been to be understood that: still can modify to embodiment of the present utility model or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technological scheme scope of the utility model request protection.
