Embodiment
[0046] figure 1 In the shown embodiment, the controller of the lower computer is connected to the upper computer through the RS232 serial port to realize data communication with the MCGS platform. The upper computer adopts PC computer. The controller in the lower computer is a single-chip microcomputer, the existing AT89S52 is selected, and the frequency of the external crystal oscillator is 11.0592MHz.
[0047] The lower computer also includes a display unit, which adopts an existing liquid crystal display such as LCD1602 integrated module, which is directly connected with the I / O port of the single-chip microcomputer. The single-chip microcomputer can transmit the current valve opening value, the valve opening setting value, and the dynamically changing valve opening value data collected during the operation of the drive motor to the display module, so that the on-site staff can know it more intuitively.
[0048] The driving motor of the opening control unit is a stepping ...

The invention discloses a pipeline valve control system and method. The system comprises a lower computer and an upper computer; the lower computer comprises a controller, an opening degree collection unit, a mode selection unit, a valve opening degree scene setting unit and an opening degree control unit, wherein the opening degree collection unit, the mode selection unit, the valve opening degree scene setting unit and the opening degree control unit are connected with the controller; the current opening degree collection unit and an opening degree setting unit are arranged in the upper computer; the controller collects a current opening degree signal of a valve through the opening degree collection unit, obtains a mode selection signal of a user through the mode selection unit, and obtains the valve opening degree set value set by the user on the scene through the valve opening degree scene setting unit; the upper computer is connected with the controller, obtains the current opening degree signal of the valve and sends the valve opening degree set value remotely set by the user to the controller; and the controller compares the opening value set on the scene or set remotely with the current opening degree value according to the control mode, and then controls the opening degree control unit to change the opening degree of the valve according to the comparison result. The system and method can work in a scene or in a remote control manner, the system cost is low, and reliability is high.
Description
technical field [0001] The invention relates to the technical fields of configuration control and valve control, in particular to a pipeline valve control system and method for controlling valves by using configuration control technology. Background technique [0002] As an important executive mechanism of pipelines, valves are widely used in water conservancy, industry and other fields. The initial valve control adopts a manual method, that is, the opening of the valve is adjusted by manually adjusting the valve mechanical arm, which is simple and low in cost. However, its disadvantages are also obvious. The opening is not easy to control and wastes manpower, and it is difficult to operate underwater and at high altitudes. [0003] With the continuous progress of the industry, the concept of intelligence has gradually become popular, and the control of valves is also developing in the direction of integration, digitization, and intelligence. The original mechanical on-sit...
