[0050] In this embodiment, the data acquisition board includes a main control chip, a pump stroke signal acquisition module, a winch signal processing unit, an AD acquisition module, and a power supply module; the main control chip, the pump stroke signal acquisition module, the winch signal processing unit, the AD acquisition module, and the power supply module are respectively connected to the bottom plate of the data acquisition board;

[0051] In this embodiment, the main control chip includes four PC ports, four PD ports, and three Port ports; the pump stroke signal acquisition module includes four Port ports; the winch signal processing unit includes four Port ports;

[0052] In this embodiment, as Figure 2 shown, the main control chip uses the STC12C5A60S2 series of single-chip microcomputer chips.

[0058] It should be noted that the sensor intelligent detector provided in the above embodiment is only illustrated by the division of the above function modules. In actual applications, the above functions can be allocated to different function modules according to needs, that is, the modules or steps in the embodiments of the present invention can be further decomposed or combined. For example, the modules in the above embodiment can be combined into one module, or further split into multiple sub-modules to complete all or part of the functions described above. For the names of the modules and steps involved in the embodiments of the present invention, they are only used to distinguish each module or step, and are not regarded as an improper limitation of the present invention.

[0059] The second embodiment of the present invention provides a sensor detection method, based on the above sensor intelligent detector, specifically: insert the sensor to be fault-detected into the corresponding socket and turn on the power switch; the sensor intelligent detector provides the required working voltage for the sensor to be fault-detected and stabilizes for a set duration;

[0060] Select the detection program of the sensor intelligent detector working software through the touch screen and run it to perform fault detection on the sensor, and then obtain the detection result. When detecting the winch sensor, if the winch sensor meets the following conditions: displays a pulse signal, the base value is 5000; when the winch sensor rotates forward one circle, 48 pulses are increased; when it rotates backward one circle, 48 pulses are decreased, then the detection result of the winch sensor is normal; otherwise, it is abnormal;

[0061] When detecting the pump stroke sensor, if the pump stroke sensor meets the following conditions: displays a pulse signal, the base value is 0, and when a metal object is swiped across the induction surface of the pump stroke sensor 10 times, the base value increases by 10 pulses, then the detection result of the pump stroke sensor is normal; otherwise, it is abnormal.

[0062] When detecting an analog sensor, a resistor is connected to the measurement end of the analog sensor. If the ratio of the change in the current of the analog sensor to the change in the connected resistor meets a preset ratio, the detection result of the analog sensor is normal; otherwise, it is abnormal. The preset ratio varies according to different situations. For example, a 4 - 20 mA analog sensor displays the current (mA) signal of the current sensor. Taking the Rosemount conductivity sensor as an example, a resistance box is connected to the measurement end of the sensor. When it is normal, the resistance box is set to 9000 ohms and the current signal (mA) is 4 mA. When the resistance box is set to 1.8 ohms, the current value is 20 mA (the correspondence between resistance and current is subject to the instruction manual of the conductivity sensor to be detected. For different sensors, the correspondence is different). If the change value of the current is inconsistent with that provided in the sensor instruction manual, it indicates that the linearity of the sensor is poor or it is damaged and needs to be repaired or replaced.
