[0040] In order to better understand the above-mentioned technical scheme, the technical scheme of the embodiments of the present application is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical scheme of the embodiments of the present application, rather than limitations on the technical scheme of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments may be combined with each other.

[0041] like Figures 1 to 4 As shown, an embodiment of the present application proposes an electric energy meter calibration line, including: a transmission line component 110; an installation component 120, the installation component 120 is connected to the transmission line component 110; an IO-Link sensor component 130, the IO-Link sensor component 130 is arranged on the installation component 120; wherein the IO-Link sensor component 130 includes an IO-Link temperature sensor 131, an IO-Link position sensor 132 and an IO-Link count sensor 133.

[0042] The electric energy meter calibration line provided in the embodiment of the present application includes a transmission line component 110, an installation component 120 and an IO-Link sensor component 130, and the IO-Link sensor component 130 includes an IO-Link temperature sensor 131, an IO-Link position sensor 132 and an IO-Link count sensor 133. Based on this, during the operation of the electric energy meter calibration line, the electric energy meter can be set on the transmission line component 110, and the performance parameters of the electric energy meter can be detected by the detection device. The ambient temperature of the area where the electric energy meter calibration line is located can be detected by the IO-Link temperature sensor 131. Further, based on the ambient temperature, it can be determined whether the calibration line is in a normal detection state and whether there is a risk of failure. The position of the electric energy meter on the transmission line component 110 can be determined by the setting of the IO-Link position sensor 132, and the number of electric energy meters that have completed the detection can be determined by the setting of the IO-Link count sensor 133. By setting up the IO-Link sensor assembly 130, the detection efficiency of the electric energy meter calibration line is high, the troubleshooting workload is greatly reduced, and the risk of failure is reduced. Preventive maintenance and optimization services and maintenance plans can be used to detect the electric energy meter calibration line. At the same time, the characteristics of the IO-Link sensor can be used to store parameters and provide additional information such as signal quality and device status.

[0043] It is understandable that a detection device is also provided on the conveying line assembly 110, and the detection device is used to detect the performance of the electric energy meter. The detection device is a traditional technology and a national standard device. The specific type and style of the detection device are not limited in this application.

[0044] It is understandable that IO-Link is a technology that can turn traditional binary or analog sensors into smart sensors. Instead of just collecting data, it allows users to remotely change their settings based on real-time feedback about the health and status of other sensors on the line, as well as the actions that need to be performed, and can adopt preventive maintenance and optimize service and maintenance plans. IO-Link technology makes sensors interchangeable through a common physical interface that uses a protocol stack and IO device description files to implement configurable sensor ports. It is truly plug-and-play and can reconfigure parameters in real time. IO-LINK is an internationally common standard two-way communication protocol. Because it is a standard protocol, it can be used between different brands. The use of IO-LINK requires the cooperation of IO-LINK master and IO-LINK devices (sensors, etc.). IO-LINK interfaces are currently divided into two types, Class A and Class B. Therefore, when choosing the master station 140 and the device, pay attention to the matching of the interface. Sensors with IO-LINK interface can obtain more parameters and process data from the sensor itself. For example, with traditional sensors, our acquisition equipment can only know the state of the signal, but not the state of the sensor, such as whether the sensor is damaged. Through the data transmitted by the IO-LINK interface, we can also obtain a series of data for process maintenance, such as temperature, working time, working voltage, switching frequency, signal quality, etc. Therefore, compared with traditional sensors, sensors with IO-LINK function can give more data. Through the cooperation of the sensor and IO-LINKmaster, the sensor signal can be transmitted to the host computer through the bus on the Master, which not only increases the distance of signal transmission, but also saves wiring. From these characteristics of IO-LINK, we can see that it has incomparable advantages. Therefore, the use of IO-LINK sensors is very huge for the automation and process automation of the meter inspection line of power grid companies. IO-LINK sensors can communicate with the control system through a standard digital interface. It can achieve the same functions as traditional sensors, such as detecting the position, color, shape, size, etc. of objects, but with higher programmability and intelligence. IO-link sensors can send diagnostic information to the control system through the digital interface, including fault diagnosis, cable disconnection, voltage anomaly and other information, so as to achieve higher reliability and efficiency. In addition, io-link sensors can also be parameterized and calibrated via a digital interface, enabling more flexible and precise control.

[0045] It can be understood that the IO-Link temperature sensor 131 is a temperature sensor based on IO-Link technology, which combines the high performance of the IO-Link communication protocol with the accuracy of temperature sensing. IO-Link is a serial digital communication protocol for a point-to-point system, and each IO device has a separate channel connected to the master station 140. This enables the IO-Link temperature sensor 131 to achieve efficient and accurate temperature measurement and seamless communication with the PLC controller 150 device.

[0046] It is understood that the IO-Link position sensor 132 is a sensor based on IO-Link technology, which is used to detect parameters such as the position, direction or displacement of an object. IO-Link is an open, fieldbus-independent communication standard that allows sensors and actuators to transmit data with the master station 140 at high speed and reliability. The main features of the IO-Link position sensor 132 include high accuracy, high reliability, fast response, and strong communication capabilities. It can accurately detect the position change of an object in real time and transmit the data to the control system to achieve precise control of the device or system.

[0047] It is understood that the IO-Link counting sensor 133 is a sensor that combines IO-Link communication technology and is mainly used to count and measure objects. This sensor can accurately record the number of objects passing by in real time and transmit the data to the control system, thereby achieving precise control of the production process. The working principle of the IO-Link counting sensor 133 generally involves the use of optical, mechanical or other sensing mechanisms to detect objects. Once an object passes through the sensor, it triggers a signal, which is then transmitted to the control system through the IO-Link interface. This communication method makes the transmission of data faster and more reliable, and reduces the errors and interference that may occur in traditional analog signal transmission.

[0051] In this technical solution, the structural composition of the installation component 120 is further provided.

The position of the sliding rod 123 can be adjusted by setting the adjusting rod 122, and then the detection position of the IO-Link sensor component 130 can be adjusted, so that the installation of the IO-Link sensor component 130 is more convenient and accurate.

It allows two-way communication between sensors and actuators and controllers, and provides remote configuration and diagnostic functions. The IO-Link protocol is based on serial communication technology and can connect devices through a standard 3-wire cable. IO-Link also provides a standardized interface that allows different sensors and actuators to be used interchangeably. It is suitable for various industrial automation applications, including robots, automated production lines, logistics and warehousing systems, etc. When used in the calibration line of electric energy meters, it can improve production efficiency and reduce maintenance frequency.

[0058] In this technical solution, the electric energy meter calibration line may also include an alarm. Through the setting of the alarm, when the PLC controller 150 learns that the detection result of the IO-Link sensor component 130 is abnormal, the alarm may be triggered to sound an alarm, so that the staff can find the abnormality of the calibration line in the first place. For example, if the detection result of the IO-Link temperature sensor 131 finds that the ambient temperature obtained by the IO-Link temperature sensor 131 has exceeded the threshold temperature, the alarm may be triggered.
