Embodiment 1
[0041] Embodiment 1: as attached figure 1 As shown, an automatic data acquisition and analysis system for workover operations includes a host computer, a PLC module, a tubing length measuring device, an automatic liquid filling system for a liquid filling tank, and a liquid level detection and alarm system for a liquid collection tank. The PLC module communicates with the upper position through a network The oil pipe length measuring device includes a laser ranging sensor and an automatic measurement trigger switch. The laser ranging sensor is used to measure the length value of the oil pipe and send the measured oil pipe length value to the PLC module. The PLC module simulates the length of the oil pipe. The quantity signal is sent to the host computer for display. After the automatic measurement trigger switch is triggered, the switch quantity signal is sent to the PLC module. After the PLC module receives the switch quantity signal once, it records one lifting oil pipe and s...
Embodiment 2
[0051] Embodiment 2: as figure 2 As shown, the control method for automatic measurement of tubing length using the automatic data acquisition and analysis system for workover operations includes the following steps:
[0052] The first step is system initialization;
[0053] The second step is to measure the length of the tubing;
[0054] In the third step, the laser ranging sensor measures the length L of the oil pipe at a frequency of 10 times per second 1 And upload to the PLC module;
[0055] In the fourth step, after the automatic measurement trigger switch is triggered, the automatic measurement trigger switch sends a switch signal to the PLC module;
[0056] The fifth step, when the PLC module receives the switch signal, select the measured length L of the oil pipe uploaded by the current laser ranging sensor 1 , according to the formula L=L 0 +L 1 Calculate the total length L of the measured tubing length, L 0 Set a value for the length of the tubing;

Embodiment 3
[0058] Embodiment 3: as image 3 As shown, the control method for automatic liquid injection using the automatic data acquisition and analysis system for workover operations includes the following steps:
[0059] In the first step, the staff selects the outer diameter of the oil pipe, determines the outer diameter of the oil pipe, and at the same time, inputs the outer diameter of the oil pipe and the actual displacement of the filling pump into the PLC;
[0060] The second step is to judge whether it is the oil pipe lifting operation, if so, then enter the third step; if not, then end;
[0061] In the third step, the PLC module judges whether the trigger signal sent by the automatic measurement trigger switch is received. If it is received, the PLC module automatically records the amount of oil pipe lifting, and if not received, manually activates the manual measurement trigger switch;
[0062] The fourth step is to judge whether the irrigation pump can be started automatica...
