Abstract
The utility model relates to an instrument display system of a mining engineering vehicle, comprising a pressure transmitter, a temperature transmitter, an A/D (Analog-to-Digital) module, a PLC (Programmable Logic Controller) and a human-computer interface. The instrument display system of the mining engineering vehicle is characterized in that the pressure transmitter and the temperature transmitter are connected with the A/D module; and the A/D module is connected with the PLC through an expansion cable, and the PLC is connected with the human-computer interface through an RS232 cable. The instrument display system is simple in engine wiring, stable, reliable in working and easy for function expansion. When the human-computer interface is displayed by using a touch screen, all numerical values (engine oil pressure, coolant temperature and the like) can be displayed through connecting an RS232 data line to the PLC, and therefore, a circuit of an electrical system of the whole mining engineering vehicle is simplified to the great extent. The touch screen reads the A/D value on the PLC, so that precise real-time numerical value display can be realized through corresponding calculation for the A/D value in a touch screen program. The instrument display system is suitable for the field of display of measurement instruments of mining engineering vehicles.
Description
Technical field
The utility model relates to the technology of instrument and meter field, furthermore, relates to a kind of mining engineering truck instrument display system.
Background technology
At present, traditional mining engineering truck instrument display packing is that stem-winder shows, the wiring of each instrument comprises one of the signal wire that comes from sensor, one of power lead, each one of background light both positive and negative polarity wiring so, causes the wiring of whole instrument panel back quite numerous and diverse.Moreover the numerical value degree of accuracy that machinery instrument shows is less, and what show only is lower limit region, and normal region and upper limit zone Three regions do not have concrete numerical value to show, and instrument are damaged easily.
Summary of the invention
In order to overcome the problem of an existing mining engineering truck instrument display system, the utility model provides a kind of ore deposit
With engineering vehicular meter display system, this system can not only measure the concrete data of tested project what are, and is conducive to judge whether normal operation of machinery.
The technical solution of the utility model: a kind of mining engineering truck instrument display system, comprise pressure unit, temperature transmitter, the A/D module, PLC, man-machine interface is characterized in that described pressure unit is connected with the A/D module with temperature transmitter, described A/D module is connected with PLC by expansion cable, and described PLC is connected with man-machine interface by the RS232 cable.
As optimization of the present utility model, described man-machine interface is touch display screen.
Because what the man-machine interface touch-screen read from PLC is the A/D value that the A/D module converts is come the PLC, it is not the actual temperature value that temperature transmitter detects, it is not the actual pressure value that pressure unit detects yet, therefore need its numerical value is calculated conversion accordingly, convert the DC4 that presses linear scaling output～20mA standard signal to, be transported to continuously the A/D module, through the A/D conversion, send into PLC.The value of A/D conversion is that display screen shows in man-machine interface after processing through plc data.
As optimization of the present utility model, described man-machine interface is added the chart element.
Fault searches during for convenient for maintaining, the design that has added the inquiry of historical data in the utility model, use the chart element in the touch-screen, five port numbers are set in chart, be used for respectively recording the Foreground and Background engine coolant temperature, Foreground and Background engine oil pressure and hydraulic reservoir air pressure.Be used again the project menu element, can jump to the named date inquiry historical data on the same day.
This is as optimization of the present utility model, and described man-machine interface is established a status lamp.Utilize the position status lamp in the man-machine interface to realize the warning functions such as high/low oil pressure, high water temperature, low-water level.
The beneficial effects of the utility model: this system can not only measure the concrete data of tested project what are, and can automatically judge whether normal operation of mining engineering truck.
The wiring of the utility model generator is simple, system stability, and reliable operation, Function Extension is easy.The application touch-screen carries out man-machine interface and only shows and need connect the demonstration that a RS232 data line just can be realized all numerical value (engine oil pressure, coolant temperature etc.) from PLC, has simplified significantly the circuit of a whole mining engineering truck electrical system.Because what touch-screen read is A/D value on the PLC, in touch screen program, it is calculated accordingly and can realize the demonstration of accurate in real time numerical value.
The utility model is applicable to a mining engineering truck measurement instrument and shows the field.
