Product Features
Measuring and controlling instrument
The measurement and control instrument is a horizontal desktop structure, which is composed of a console, a lower computer, and an upper computer. The upper and lower computers are built in the console. The upper right of the console is a digital window, which displays the main parameters in real time. A 19-inch color LCD display is embedded in the upper left of the console and fixed on the panel. The panel is oil-resistant and flexible, and displays the main and auxiliary parameters. The main and auxiliary parameters are matched according to the specified technical requirements.
The main functions of the lower computer of the measuring and controlling instrument
1. The system takes the imported industrial industrial control half-length motherboard as the core, imported readable and writable DOM, and the entire measurement and control circuit adopts modular design, fully digital (DDC) setting and control.
2. High-precision strain-type tension and pressure sensors realize precise digital measurement of engine output torque;
3. Magnetoelectric speed sensor realizes high-precision instantaneous speed measurement;
4. It has the functions of random non-disturbance switching control, throttle sudden unloading, and dynamometer load protection processing;
5. The measurement parameters can be set by the user on the computer to set the action mode of each level of alarm.
6. Lower computer system control function
7. The dynamometer and engine throttle adopt dual-loop direct digital PID control, with the platform 3500*1400*250mm following automatic control functions: dynamometer: constant position, constant torque, constant speed of water gate (external characteristics), engine: constant position of throttle, constant speed of throttle
Host computer control system configuration and main functions
Advantech industrial computer is selected as the upper computer, and the industrial computer and the required boards are selected from well-known brands. Send the serial port reserved for future expansion to the user, and integrate it into the computer system according to the communication protocol provided by the user.
Industrial computer configuration: cool dual-core 2.6G or more, RAM: 1G, hard disk: 250G,
10/100M adaptive network card, 19-inch LCD display, RS232/485 expansion card
record function
1. The control system needs to upload and store measurement data and fault information in real time. Automatically save data to the network database, temporarily save the data to the local database when the network database fails, and then dump to the network database at an appropriate time.
2. Automatically generate reports and curves.
3. Alarm protection function. The measurement control system has three levels of alarm and protection functions. Each measurement parameter can be set by the user on the computer. The action mode of each level of alarm:
4. The entire upper computer control system is centered on special configuration software, equipped with software such as test condition editing, test data processing, and test processcontrol. The data exchange betweenthe upper and lower computers is realized through the field bus, and the entire engine test control process is completed. All data processing and screen display. All measurement parameters can be displayed on the LCD. Display mode: digital display and curve display. Torque, power and fuel consumption can be automatically corrected by the computer, and the correction formula can be automatically selected according to the model (according to the national standard GB/T18297-2001), or manually
input and calculated by the operator.
5. Automatically complete various program control tests according to the set steps. The combination of steps can be combined arbitrarily according to the experiment. According to the JIS standard and GB/T6072.1-200 national standard, the measured data is calculated, corrected, statistically analyzed and output for power, torque and fuel consumption
correction tool
The calibration of the eddy current dynamometer is carried out using the mass value of the standard weight and the allowable range of the calibration code value of the calibration program, because the calibration digital value has a certain range of space (for example, a sensor with a maximum weighing capacity of 500kg, its 20kg weight The value multiplied by the length of the calibration arm can be calibrated to a display value of 200N. If the actualmass of the calibration weight is 200kg, the calibrated display value is 2000N.
