Control method of multi-point synchronous intelligent tensioning system
The invention provides a control method of a multi-point synchronous intelligent tensioning system. The control method includes the following steps that the pressure value of the system is read, and whether the pressure value of the system is higher than a target pressure value by 2-3 MPa or not is judged; if not, the pressure value of the system is adjusted to be within the range, and if yes, a ball valve is opened and oil inflow is started; pressure values of jacks on various points of are read, and whether the maximum difference value of the pressure values of the jacks on various points is within the set range or not is judged; if the maximum difference value of the pressure values of the jacks on various points is within the set range, jacking continues after pressurization stops, judgment in next round starts till the pressure values of various points become the target pressure value, the ball valve is closed, oil inflow stops, and tensioning ends; if the maximum difference value of the pressure values of the jacks on various points is not within the set range, pressurization is started, jacking continues, and judgment in next round starts till the pressure values of various points become the target pressure value. When whether the maximum difference value of the pressure values of the jacks on various points is within the set range or not is judged, a plurality of stair difference values are set so that judgment can be performed step by step, the cable force of various inhaul cables is adjusted gradually, and therefore the inhaul cables can reach the target force value gradually, and time and labor are saved.
