Example Embodiment

[0021] Attached figure 1 This is a specific embodiment of the present invention. The invention is based on the big data-based online detection system for abnormal precharge pressure of the accumulator, which includes a power source, an accumulator, an actuator, a big data system and a controller, and is characterized in that the power source connects the power source and the The accumulator is connected, the inlet and outlet of the actuator and the outlet of the accumulator are connected by accessories, the pressure sensor is installed at the outlet of the accumulator, and the controller collects the data of the pressure sensor, temperature sensor and displacement sensor , Filter, and send processed data to the big data system. The output flow of the accumulator is obtained indirectly through the displacement sensor used to detect the displacement value of the actuator. The displacement sensor can detect linear or angular displacement data, which is combined with the displaceme...

Abstract

The invention belongs to the technical field of hydraulic pressure, and particularly relates to an online detection system and method for abnormity of pre-charging pressure of an energy accumulator onthe basis of big data. The online detection system for the abnormity of the pre-charging pressure of the energy accumulator on the basis of the big data comprises a power source, the energy accumulator, an actuator, a big data system and a controller, wherein the power source is connected with the energy accumulator through an accessory; an inlet and outlet opening of the actuator is connected with an outlet of the energy accumulator through an accessory; a pressure sensor is mounted at the position of an outlet of the energy accumulator; the controller acquires and filters data of the pressure sensor, a temperature sensor and a displacement sensor; and the processed data are transmitted to a big data system. The online detection system for abnormity of the pre-charging pressure of the energy accumulator on the basis of the big data has the beneficial effects that manual operation can be relieved, downtime of the system is shortened, remote automatic monitoring is realized, and reliability of the system is improved.

Description

technical field [0001] The invention belongs to the field of hydraulic technology, and in particular relates to an online detection system and method for abnormal pre-charging pressure of an accumulator based on big data. Background technique [0002] The hydraulic accumulator is an energy storage element commonly used in hydraulic systems. Its energy storage is achieved by compressing gas. The airtightness of the air cavity is an important prerequisite for determining the reliability of the accumulator. Therefore, after the accumulator is connected to the hydraulic system and starts to work, it is necessary to regularly check the pre-charge pressure value of the accumulator to prevent the accumulator from leaking and failing. The usual solution is to stop the work of the system, manually connect the pressure gauge to the outlet and outlet of the accumulator, and then slowly release the pressure medium of the accumulator until the pressure value of the pressure gauge drops s...
