Problems solved by technology
[0008] Based on the combination of the above several fluid power systems and computers, these methods either rely on the form change of the control electrical signal (D / A conversion, pulse modulation), or special design of the fluid element structure (position sensor method). ), so there are many intermediate links, the structure is complex, the corresponding relationship between the action of the fluid power element and the controlled digital signal is not clear, and it is not convenient for the processing and control of the computer

Embodiment Construction
[0026] The inventive method is further described in conjunction with accompanying drawing:
[0027] The simple control system adopting the device of the present invention includes an energy supply part, an on-off valve, an electric-fluid pulse generator, a fluid power element and a computer. The energy supply part provides continuous working fluid to the system, and the continuous fluid is sent to the electro-fluid pulse generator through the switching valve. The on-off valve is controlled by computer commands to open or close. The pulse flow output by the electro-fluid pulse generator is used to execute the action of the fluid power element.
[0028] When the fluid power element is required to move a certain amount, first input this amount into the computer, and then the computer issues instructions to open the switch valve, and the working fluid will push the piston in the electric-fluid pulse generator to reciprocate to output a series of fluids. pulse. The amount of eac...

The invention belongs to fluid transmission control technology in mechanical engineering. The digital pulse digital flow transmission and control method involved in the fluid system performs discrete quantification of the working fluid in the fluid system, and converts the continuous analog flow fluid in the fluid system into a series of countable and definite fluid pulses, And the amount of each fluid pulse is constant and equal, forming a pulse flow. A series of fluid pulses act on the fluid dynamic components, and at the same time, a series of fluid pulses are accompanied by electrical pulse signals corresponding to them one by one. After the electrical pulse signals are processed by computer counting, calculation, comparison, etc., they control the working state of the fluid switching valve, and then control the fluid. The work of power components.
Description
Technical field [0001] The invention belongs to fluid transmission control technology in mechanical engineering, and mainly relates to a digital pulse digital flow transmission and control method of a fluid system. Background technique [0002] With the increasing development and wide application of computers, using computers to carry out real-time digital control of fluid transmission systems is an important trend in the future development of fluid technology. However, if the fluid transmission and control technology can be better and more conveniently combined with computer technology, the most important thing is to give, express and realize the fluid transmission and working information in digital form. The methods currently used mainly include the following: [0003] 1. D / A conversion method: [0004] The digital signal given by the computer is converted into an analog electrical signal through the D / A conversion device, and then the proportional valve or the electro-h...
