Embodiment Construction

[0078] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0079] like figure 1 As shown in the figure, an automatic recognition device for indication value of a pointer instrument based on the Internet of Things and machine vision includes a main station control center, a gateway and a base station. The base station communicates with the gateway through a GPRS or GSM network; the gateway is connected to the main station control center , used to pass information.

[0080] The base station has two building blocks:

[0081] like figure 2 As shown, the first type includes pointer meter 1, wired camera 7, base station computer 4 and GPRS wireless terminal 6, and wired camera 7 is positioned at the front of pointer meter 1 dial, and wired camera 7 and GPRS wireless terminal 6 are connected with base station computer respectively 4 communication connection.

[0082] like image 3 As shown, the second t...

Abstract

The invention discloses a pointer type instrument indicating value automatic identification device and method on the basis of internet of things and machine vision. The device comprises a master station control center, a gateway and a base station, wherein the base station comprises a pointer type instrument dial plate to be measured, a video camera, a computer and a general packet radio service (GPRS) wireless terminal. A clear zero moment pointer type instrument dial plate image is shot by using the video camera and stored in the computer, and relevant parameters are set according to practical situation. Images of the pointer type instrument dial plate to be measured are shot in real time by using the video camera, image processing based on an intelligent optimization algorithm is performed on the shot images, a pointer type instrument indicating value is figured out and sent to the master station control center through the GPRS wireless terminal to replace artificial reading, the defect and the problem that the artificial reading is high in labor intensity, large in error, low in efficiency and the like are overcome and solved, and communication efficiency between the master station control center and the base station is improved.

Description

technical field [0001] The invention relates to the field of indicator value recognition, in particular to a device and method for automatic recognition of pointer meter values ​​based on the Internet of Things and machine vision. Background technique [0002] At present, my country's electric power, petroleum, chemical and other industries still use a large number of pointer instruments, especially in some special occasions (such as gas stations). The identification of the indication value of the pointer instrument is mainly done manually, and the indication value is read by manually observing the pointer of the instrument dial. This observation method is easily affected by subjective factors such as human observation angle and observation distance, and the error is large. Reading is labor-intensive and inefficient. In remote control, due to the low efficiency of information communication between each base station and the master station control center, each base station ca...
