Example Embodiment

[0029] The measurement and control system for the single-cylinder engine test bench provided by the present invention is based on a self-developed single-cylinder engine test bench. Under the basic mode of the distributed control system, a hierarchical module structure is adopted to integrate diversified and diversified engines. Monitoring and control tasks are broken down into relatively independent links, and are designed into independent functional sub-modules and sub-programs according to the difference in function. Through the form of network communication, a high degree of integration and association is realized, and the scheduled test research tasks are completed through the unified management and scheduling coordination of the host computer main program.

Abstract

The invention discloses a measuring and controlling system for a single-cylinder engine testboard, which comprises an upper computer, an intelligent instrument, a PLC (programmable logic controller), a plurality of sensors and a first electric actuator, wherein the upper computer is respectively connected with the intelligent instrument and the PLC; the upper computer sets a stable judgment interval for the operational parameters of an engine and sets an alarming threshold value, and downloads online to the intelligent instrument; the intelligent instrument is respectively connected with the sensors and the first electric actuator, so as to obtain operational parameters of the engine at a monitoring point during the running process of a single cylinder engine; further the working state of the first electric actuator is adjusted, and an auxiliary system is controlled; the intelligent instrument is further connected with the PLC and used for conveying warning signals to the PLC; and the PLC gives an alarm for prompting according to the warning signals. In the invention, through the application of the intelligent instrument, discrepancies caused by multitasking and processing speed of the upper computer can be overcome, task dispersion is achieved, and the reliability and the stability of the overall system are improved.

Description

technical field [0001] The invention relates to a measurement and control system, in particular to a measurement and control system for a single-cylinder machine test bench. Background technique [0002] The development of the engine test bench began in the 1940s and 1950s. It is the main equipment for engine performance tests. Its level directly affects whether it can faithfully reflect the performance of the engine and whether it can provide the basis for engine design and improvement. In the process of engine development, development, production and use, the engine test bench link is very important for engine theory, design and manufacture of new products, research and improvement of the performance of engines and their parts, and correct guidance for production, maintenance and use. meaning. With the application and development of computer technology and electronic technology in the measurement and control system of the test bench, the modern engine test bench integrate...
