Embodiment Construction
[0009] figure 1 Shown is the block diagram of the hydraulic impactor intelligent control system. The intelligent control system mainly composed of PC microcomputer 1, controller 2, sensor 3 and actuator 5 monitors the hydraulic impactor 4 in real time. First, the sensor 3 collects the nitrogen chamber pressure of the hydraulic impactor 4, the piston front cavity pressure, the piston rear cavity pressure, the high-pressure oil circuit flow and the low-pressure oil circuit flow and other parameters and sends them to the data collector of the controller 2. After preprocessing, the simulated The signal is converted into a digital signal and input to the PC microcomputer 1, which is stored in the RAM memory used as a dynamic database in the machine, and various symptom data that may be generated by the self-defined hydraulic impactor during operation are pre-stored in the ROM memory, and passed through the PC The comparator of the expert system of the inference machine compares an...

The invention provides an intelligent control system of a hydraulic breaker, which belongs to the information processing technique range. The system is mainly composed of a PC microcomputer, sensors, a controller and an actuating mechanism. Various sensors collect state real-time parameters of the hydraulic breaker which are output to the PC computer installed on a host after the preprocessing by a data collector of the controller and are stored into a dynamic database to be compared with the pre-stored symptom parameters of a self-defined hydraulic breaker, and after an expert system of the PC computer compares the parameters, symptom data required by the expert system corresponding to the spot can be obtained and compared with related symptom data of a knowledge rule base of an expert system in an inference machine, so as to deduce a realistic conclusion and a processing scheme, and the actuating mechanism adjusts the corresponding operational parameters of the hydraulic breaker in real time to realize the function of automatically adjusting the impact energy and impact frequency of the hydraulic breaker. The invention supplies a gap that the hydraulic control system of the general hydraulic breaker can not automatically adjust the impact energy and impact frequency of the hydraulic breaker; and can automatically adjust the impact energy and impact frequency of the hydraulic breaker at any moment according to different degrees of hardness of the impacted object. When the hardness of the impacted object is high, the impact energy is increased, and the impact frequency is reduced; and when the hardness of the impacted object is low, the impact energy is reduced, and the impact frequency is increased, so the purpose of energy saving can be realized.
Description
technical field [0001] The invention belongs to the technical scope of information processing, and in particular relates to an intelligent control system of a hydraulic impactor. technical background [0002] The hydraulic impactor is a new type of hydraulic engineering equipment widely used in the crushing of mine rocks and the demolition of concrete structures. The main structure includes basic components such as hydraulic impact pistons, reversing valves and nitrogen chambers. Its working principle is that high-pressure oil and nitrogen pressure drive the impact piston to reciprocate and impact the steel brazing, and the impact energy is transmitted to the working object through the steel brazing to achieve the purpose of external work. However, most of the current hydraulic impactors cannot automatically adjust the impact frequency and impact energy, and often cannot meet the requirements of optimizing work under various working conditions. Therefore, under different wo...
