The evaporator is an important part in four refrigeration parts, and low-temperature condensed liquid passes through the evaporator to exchange heat with outside air, gasify and absorb heat, so that the refrigeration effect is achieved.

In the prior art, because the common industrial evaporator has larger volume and more parts, when some parts are abnormal, the evaporator can be abnormal. Whether the evaporator is in a normal state or not generally requires judgment of an internal state and an external state. At present, the internal state generally collects working data of an internal system through the evaporator, and whether the evaporator is in a normal working state is judged by combining the collected internal data. The external state is often monitored by manual inspection, for example, by manually determining whether the position of the component is in a normal position, whether the component is inclined, and the like.

However, in the prior art, a monitoring mode for whether the external state of the external device of the evaporator is abnormal is not accurate enough, and the efficiency is low.

The monitoring area is provided with an image acquisition device. A plurality of standard state diagrams of the evaporator can be acquired based on the image acquisition devices arranged at the monitoring areas. The standard state diagram is a picture of the standard working states of a plurality of parts taken by different monitoring areas of the evaporator, for example, the standard state is collected when the evaporator is just assembled.

Each standard state diagram typically includes a first component and a plurality of second components of the evaporator. The first component is a component with higher stability in the evaporator, and the components are generally not displaced due to faults, such as a fixed steel frame, a circulating pipe and the like, which are preset manually.

And acquiring a contour coordinate set corresponding to the second contour.

Specifically, a contour coordinate set corresponding to the second contour is obtained, and a maximum transverse value, a minimum transverse value, a maximum longitudinal value and a minimum longitudinal value in the contour coordinate set are obtained according to the contour coordinate set. The maximum transverse value is the maximum X-axis coordinate value. The minimum transverse value is the minimum X-axis coordinate value. The maximum longitudinal value is the maximum Y-axis coordinate value. The minimum longitudinal value is the minimum Y-axis coordinate value. The maximum X-axis coordinate value, the minimum X-axis coordinate value, the maximum Y-axis coordinate value and the minimum Y-axis coordinate value in the profile coordinate set are acquired and act on the convenience for subsequent calculation of the intermediate value of the X axis and the Y axis.
