Multiple gas-circuit gas pressure on-line quantitative distribution system

Abstract

The invention discloses a multiple gas-circuit gas pressure on-line quantitative distribution system which comprises a plurality of pressure sensor nodes, a plurality of pressure control units, a main processor and a monitoring host, wherein the main processor is used for carrying out analysis processing on a gas pressure control curve of a plurality of controlled gas circuits and correspondingly calculating a gas pressure distribution proportional relation among a plurality of controlled gas circuits at any moment; the monitoring host is distributed in a remote data monitoring center and is used for controlling the pressure control units according to the gas pressure distribution proportional relation calculated by the main processor; and a pressure detection and control device is formed by the pressure sensor and the pressure control unit which are arranged in each controlled gas circuit. The multiple gas-circuit gas pressure on-line quantitative distribution system has reasonable design, is convenient to lay, is simple and convenient to operate and has reliable performance and good using effect. The main processor can be used for automatically calculating the gas pressure distribution proportional relation among a plurality of controlled gas circuits at any moment and the remote allocation is carried out by the monitoring host. Each detection node can be used for notifying the monitoring host actual pressure information in the gas circuits in a wireless network mode.

Description

technical field [0001] The invention belongs to the technical field of on-line monitoring, and in particular relates to an on-line gas pressure quantitative distribution system with multiple gas paths. Background technique [0002] Existing industrialized production is moving towards automation. Automation is not only efficient, but also saves manpower and material resources. However, in the actual production process of some small and medium-sized enterprises in China, the goal of full automation is still not achieved, which will bring a series of problems, such as the unstable performance of the produced products and the inability to achieve precise control of the process. The control link in the production process of the enterprise is mainly the control of parameters such as temperature, pressure, and flow. Therefore, many instruments are used in the production workshop to indicate various indicators of the substances in the pipeline. How to monitor the production process...

Problems solved by technology

For gas pressure control involving multiple gas circuits, manual monitoring is far from meeting production needs. If a large number of sensors are used for wired monitoring, the wiring of the entire control and monitoring system will be very complicated. Once a fault occurs, it will be troublesome to repair and affect the system. The system cost is also relatively high
