The terminal 12 is configured to determine whether the weight of the electric meter part is qualified based on the actual weight and a preset standard weight of the electric meter part, obtain a first determination result, determine an actual color of the electric meter part based on the image, determine whether the color of the electric meter part is qualified based on the actual color and a preset standard color of the electric meter part, obtain a second determination result, determine an actual shape of the electric meter part based on the image, determine whether the shape of the electric meter part is qualified based on the actual shape and a preset standard shape of the electric meter part, and obtain a third determination result, and determine that the electric meter part is qualified at least when the first determination result, the second determination result and the third determination result are all yes.
Specifically, the embodiment of the application presets the standard weight, standard color and standard shape of the electric meter part, the weight of the electric meter part can be judged whether to be qualified or not based on the actual weight of the electric meter part sent by the weighing device and the preset standard weight of the electric meter part, a first judgment result is obtained, the actual color and the actual shape of the electric meter part are determined based on the image sent by the image acquisition device in order to judge whether the color and the shape of the electric meter part are qualified or not, the color of the electric meter part can be judged whether to be qualified or not based on the actual color and the preset standard color of the electric meter part, a second judgment result is obtained, the shape of the electric meter part can be judged whether to be qualified or not based on the actual shape and the preset standard shape of the electric meter part, and a third judgment result is obtained. .

According to the ammeter part detection system provided by the embodiment of the application, the ammeter part is not required to be detected manually, and the volume of the ammeter part is not required to be measured, so that the cost is reduced, the detection time of the ammeter part is saved, the detection efficiency is improved, the detection error caused by human factors can be avoided, the accuracy of the ammeter part detection is improved, and the accuracy and the reliability of ammeter metering are ensured.
Further, because the weight and the color of the ammeter part are related to the material of the ammeter part, whether the weight and the color of the ammeter part are qualified or not is judged through the terminal, the detection of raw materials of the ammeter part can be realized, the problem that the raw materials of the ammeter part do not reach standards is avoided, and because the shape of the ammeter part is directly related to the assembly and the use of the ammeter part, whether the shape of the ammeter part is qualified or not can be judged through the terminal, thereby avoiding the situation that the ammeter part cannot be assembled and cannot be used.
Optionally, the above electric meter part detection system may further include: a size measuring device.
Based on this, the terminal 12 is further configured to, when the third determination result is yes, determine a difference portion where the actual shape does not overlap with the standard shape by using a contrast overlap method, and send a measurement instruction for measuring actual size data of the difference portion to the size measurement device.

and the terminal 12 judges that the electric meter part is qualified when the first judging result, the second judging result, the third judging result and the fourth judging result are all yes.
Specifically, in order to improve the accuracy of detecting the electric meter part, the accuracy and the reliability of metering of the electric meter are improved, and the electric meter part is judged to be qualified only when the first judgment result, the second judgment result, the third judgment result and the fourth judgment result are all yes, namely, only when the weight, the color, the shape and the size of the difference part of the electric meter part are all qualified.
In the embodiment of the application, the terminal not only judges whether the weight, the color and the shape of the ammeter part are qualified, but also judges whether the size of the difference part is qualified based on the actual size data of the difference part, which is measured by the size measuring equipment and is not coincident with the standard shape, and the standard size data of the preset difference part, and only when the weight, the color, the shape and the size of the difference part of the ammeter part are all qualified, the qualification of the ammeter part is judged, thereby further improving the accuracy of ammeter part detection and the accuracy and the reliability of ammeter measurement.
Optionally, the weighing device may be an electronic scale.

The image acquisition device can be a camera, and the color of the surface with the too small area can not be determined in consideration of the fact that the area of the surface of the ammeter part is possibly too small, so that the clamp can be used for enabling the surface with the largest flatness of the ammeter part to face the camera, and the terminal can determine the color of the surface with the largest flatness of the ammeter part based on the image. In order to enable the terminal to determine the actual shape of the electricity meter part, the image acquired by the camera may be a perspective view of the electricity meter part.
In the embodiment of the application, the clamp utilizes the pneumatic device to fix the ammeter part, so that the clamp can utilize the pneumatic device to rapidly tighten the ammeter part, the detection speed of the ammeter part is accelerated, and the accuracy of the determined actual color, actual shape and actual size data of the ammeter part is improved. The clamp faces the surface with the largest flatness of the ammeter part to the camera so that the terminal can determine the color of the surface with the largest flatness of the ammeter part based on the image, and the situation that the color of the surface with the too small area of the ammeter part cannot be determined is avoided.
Alternatively, considering that the three-dimensional meter is a high-precision measuring device which can accurately measure the size of an object, the above-mentioned size measuring device may be a three-dimensional meter which can measure the actual size data of the differential portion with the center of the jig as a measurement reference and the ground plane as a bottom reference in order to ensure the accuracy of the actual size data of the differential portion measured by the three-dimensional meter.
In the embodiment of the application, the three-coordinate instrument takes the center of the clamp as a measurement reference, and takes the ground plane as a bottom reference to measure the actual size data of the difference part, so that the accuracy of the actual size data of the difference part measured by the three-coordinate instrument is ensured.
Optionally, in consideration of color deviation of other light sources on the color of the ammeter part, the actual color determined by the terminal is inaccurate, and in order to ensure the accuracy of the actual color of the terminal, the ammeter part detection system may further include a lamp for irradiating constant light on the ammeter part, so as to avoid color deviation of other light sources on the color of the ammeter part, and the actual color determined by the terminal is inaccurate.
