DETAILED DESCRIPTION

[0016] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0017] The following detailed description is an exemplary description, which is intended to provide further detailed description of the present invention. Unless otherwise specified, all technical terms used in the present invention have the same meaning as those generally understood by those skilled in the art to which the present application belongs. The terms used in the present invention are only for describing specific embodiments, and are not intended to limit exemplary embodiments according to the present invention.

[0018] Example 1 like Figure 3 As shown, Embodiment 1 of the present invention provides an unattended system for lightning arrester testing, comprising: An equipment monitoring module is arranged on the corresponding lightning arrester test equipment, and the equipment monitoring module is used to monitor the data of the corresponding lightning arrester test equipment; wherein the lightning arrester test equipment is provided with an equipment display screen; when the lightning arrester test equipment has its own control terminal, the equipment monitoring module is the control terminal, and the control terminal includes a control terminal display screen, and the control terminal monitors the data of the corresponding lightning arrester test equipment and transmits it to the control terminal display screen; when the lightning arrester test equipment does not have a control terminal, the equipment monitoring module is a camera device installed on the lightning arrester test equipment, and the camera device is used to monitor the equipment display screen; A video collection module is used to obtain the code stream data of each control terminal display screen and / or device display screen, and send the code stream data to the remote monitoring module; The remote monitoring module is used to play the code stream data as a video stream on the remote monitoring interface.

[0019] It should be noted that the lightning arrester test equipment referred to in this solution is provided with an equipment display screen, and the equipment display screen may be various meters or display screens for displaying the operating parameters of the lightning arrester test equipment.

[0020] The data monitored by the camera device is image data, including video data, etc. The data monitored by the camera device is transmitted in the form of code stream data.

[0021] Preferably, the imaging device is specifically a camera.

[0022] Due to the different control methods of lightning arrester test equipment. For lightning arrester test equipment with a control terminal, this solution sends the data of the control terminal display screen to the cloud server; for lightning arrester test equipment without a control terminal, the data of the device display screen is obtained by installing a camera device and sent to the cloud server. The cloud server collects and organizes the received data in real time and provides an interface to the outside world. The service can be called through the interface on the APP side for users to interact.

[0023] In a specific embodiment, if the arrester test equipment has an equipment monitoring module formed by a control terminal, the data of the control terminal display screen is collected and processed in the form of a video RTSP code stream through the video collection module, and after format conversion on the cloud server, the video stream is finally output on the PC and APP ends for display, and the video stream format includes HLS, WebRTC, etc.; if the arrester test equipment only has a device display screen that is not controlled by computer software, a camera is installed on the arrester test equipment, and the device display screen of the arrester test equipment is directly monitored by the camera. Data is collected and processed by the camera in the form of RTSP code stream, and the video after code stream processing is transmitted to the PC and APP ends through the cloud server. That is, the content of video playback is divided into two situations, the projection of the control terminal display screen and the video data collected by the additional camera. It can also be displayed on the Web end through real-time video playback.

[0024] The video collection module is set in the cloud server. The video collection module communicates with the equipment monitoring module on the lightning arrester test equipment through the optical fiber switch, and is used to realize the data interconnection between multiple lightning arrester test equipment and the cloud server and the client; The remote monitoring module is set on the PC and APP ends to play the code stream data as a video stream on the remote monitoring interface.

[0025] like Figure 1 As shown, for the convenience of explanation, it is assumed that the arrester test equipment has its own control terminal (that is, a console controlled by the original software), and this example is used to introduce the data transmission method. The arrester test equipment is connected to the fiber optic switch of the corresponding laboratory through a network cable, and is connected to the converged fiber optic router through optical fiber. After that, it is converged to the cloud server of the laboratory remote management system through the Internet. The cloud server displays the monitoring results of each arrester test equipment on the client's PC or APP. By connecting to the fiber optic switch, data interconnection between multiple arrester test equipment and the client can be achieved. When an abnormal situation occurs, the laboratory remote management system can respond quickly and deploy logistics personnel to quickly handle the abnormality.

[0026] In an optional embodiment, a data acquisition module is deployed on the lightning arrester experimental equipment, and a data analysis module is deployed on the cloud server; wherein: A data acquisition module, used to identify and acquire user preset information data in the code stream data corresponding to the control terminal display screen and / or the device display screen, and to acquire physical quantity data of the arrester test equipment; Specifically, the data acquisition module is used to collect physical quantity data of the arrester test equipment, such as the temperature collected by the temperature collector installed on the salt spray arrester test equipment, and the flow rate collected by the flow meter; on the other hand, the data acquisition module extracts the data information that users are concerned about from the terminal display screen and the equipment display screen, and performs text recognition on the display screen through the acquisition plug-in, such as the OCR / OCV module in the LabVIEW Vission Assistant; the information data is processed by the data acquisition and analysis module and then transmitted to the PC and APP ends.

[0027] The data analysis module is used to analyze and process the data collected by the data acquisition module, including: unifying the data value unit; judging whether to issue an alarm based on the relationship between the data value and the preset alarm condition, and pushing the alarm information to the PC and / or APP. When the PC and APP receive the alarm information, they can provide sound and light alarms to remind the test personnel.

[0028] Specifically, since the data acquired through the data acquisition module are only data values, the units of the acquired data values ​​are unified when performing data analysis.

[0029] The data analysis module also matches the data obtained by the data acquisition module, the lightning arrester test equipment to which the data belongs, and the relevant person in charge.

[0030] For example, when analyzing the accelerated aging arrester test equipment, data such as voltage values, temperature values, and ambient temperature during the test can be collected. After being analyzed by the data acquisition and analysis module, the data can be pushed to the PC, APP, and PC of the relevant person in charge in the main control room.

[0031] The physical quantity data of the lightning arrester test equipment is collected by means of sensor equipment installed on the lightning arrester test equipment; the sensor equipment includes but is not limited to voltage sensors, temperature sensors, flow meters, etc.

[0032] In an optional embodiment, the cloud server is also deployed with a long-term data monitoring module, which is used to store historical data corresponding to data that needs to be monitored and recorded for a long time in a cloud database. The cloud database sends the stored historical data to the PC and / or APP. The PC and / or APP generates data records in time units based on the received historical data for experimenters to view. The interval of the time unit is customized by the user.

[0033] Unattended lightning arrester test The unattended lightning arrester test system also includes an emergency power-off device; wherein, the emergency power-off device includes a control system and an execution system; the control system is installed in the control box of the lightning arrester test equipment, and is used to receive the emergency power-off command issued by the cloud server; the execution system is set on the lightning arrester test equipment, and is used to receive the command of the control system to perform power-off operations. The execution system is mainly a programmable contactor, etc. Among them, the control system can report the power supply status or power-off status, and receive the power-off command issued by the cloud server, host computer, etc.

[0034] The data analysis module compares the threshold value set for each test with the actual data. If it exceeds the threshold range, the remote monitoring PC and APP will issue a warning, send a short message to the operator's mobile phone, and cut off the power at the same time. The operator can also judge whether the data is abnormal. If it is abnormal, the test can be stopped manually, such as cutting off the power on the PC or APP.

[0035] As an example, when an alarm message is received from the data analysis module, an emergency power-off instruction is generated through the PC and / or APP and transmitted to the cloud server. The cloud server sends the emergency power-off instruction to the control system, and the control system controls the execution system to perform a power-off operation.

[0036] As an example, arrester test equipment includes various types of long-term operation equipment, such as salt spray arrester test equipment, thermal machine arrester test equipment, light aging arrester test equipment, horizontal tensile testing machine, climate aging arrester test equipment and accelerated aging arrester test equipment.

[0037] Then, the preset alarm conditions include: A: Alarm conditions corresponding to the horizontal tensile testing machine: preset force and displacement threshold range; B: Alarm conditions corresponding to the salt spray arrester test equipment: preset threshold ranges of voltage, current, temperature, and flow; C: Alarm conditions corresponding to the light aging arrester test equipment: preset light intensity threshold range; D: Alarm conditions corresponding to thermal machine arrester test equipment: preset force, time, and temperature threshold ranges; E: Alarm conditions corresponding to the weather aging arrester test equipment: actual voltage and test temperature threshold range in the three preset test circuits; F: Alarm conditions corresponding to the accelerated aging arrester test equipment: preset voltage, temperature, and flow threshold ranges.

[0038] It should be noted that the specific threshold values ​​of the above-mentioned preset alarm conditions can be set according to actual conditions and will not be elaborated in this solution.

[0039] The following is a specific example to illustrate this solution: Taking the salt spray arrester test equipment as an example, the test in the salt spray arrester test equipment needs to work continuously for 1000 hours under certain voltage and salt spray conditions. The salt spray arrester test equipment lacks temperature sensors, flow meters, etc.

[0040] 1) For salt spray arrester test equipment with its own control terminal, there is a data communication interface available. Modification method: Install collection plug-in, temperature probe, temperature collection card, and flow meter.

[0041] The acquisition plug-in in this embodiment recognizes the image text through the OCR / OCV module in LabVIEW Vission Assistant, removes unnecessary text data and summarizes it, encodes it according to the corresponding lightning arrester test equipment signal, assembles it into JSON format, and sends it to the cloud server through the udp protocol. The cloud server processes it again and presents it to the APP and PC. The temperature probe, temperature acquisition card, etc. are used to collect temperature data, and the flow meter collects flow data. These data are parsed by the data acquisition and parsing module and presented to the APP and PC.

[0042] On the cloud server, the data of the control terminal display screen is collected and processed as RTSP (Real Time Streaming Protocol) stream data, and then projected to the software on the PC and APP for playback.

[0043] It should be noted that in LabVIEW Vision Assistant, OCR (Optical Character Recognition) and OCV (Optical Character Verification) are used to process and verify characters in images.

[0044] 2) For salt spray arrester test equipment without control terminal, a camera is installed on the display screen of the arrester test equipment. The video data captured by the camera is transmitted to the cloud server, which processes the data and forwards it to the PC and APP for playback.

[0045] In an optional embodiment, since the interface protocols, corresponding control terminals, and control terminal operating systems of different lightning arrester test equipment may be different, in order to realize the viewing and control of the operation of the lightning arrester test equipment, the present invention collects video data through the display screen of the device's corresponding control terminal and the camera installed on the device display screen, and displays it on the remote PC and APP software, and finally presents it in the form of video playback, so that users can remotely observe the operation of each device.

[0046] like Figure 2 As shown, as an optional embodiment, software, i.e., laboratory remote management system, is set on the PC or APP side to realize remote control and display. The software development platform is Windows, the back end is developed using C# language, and the front-end access layer uses JS and HTML language, and combines Vue framework and Bootstrap and other front-end frameworks to provide a rich user interaction experience. The access layer of the software is the entrance to the entire software human-computer interaction. The software is developed in the mainstream Browser / Server (B / S) mode, so that users can easily access it through the browser. Among them, the browser part recommends the use of Chrome kernel browser to ensure the best compatibility and performance. Optionally, in the front-end access layer, HTML, CSS and JS are used to build page applications, and front-end frameworks such as Vue framework and Bootstrap are also introduced. These frameworks provide developers with rich components and tools to make page development and maintenance more efficient and simple. In addition, the software backend also includes multiple server-side components, such as login, alarm management, real-time monitoring, video monitoring, user management, device management, etc., which realize various functions and business logic. In terms of network communication, mainstream technologies such as http and nginx are used to ensure stable data transmission and efficient processing. At the same time, the software also provides a variety of API interfaces, such as multi-user muApi, remote monitoring rmuApi, configuration configApi, business management bmApi and video cameraApi.

[0047] The present invention can monitor the test status of multiple lightning arrester test equipment. The operator of each test can see the status of the test station he is responsible for at the office station and on the mobile phone, and there will be prompts (interface prompts, SMS prompts) when the relevant data exceeds the threshold, and emergency power can be cut off in the event of an accident. There will be an alarm reminder for test abnormalities, and the general person in charge can see the status of multiple tests on the mobile phone, and can stop multiple tests. The test personnel and the general person in charge can check the test status on the APP side at home, and can know the test situation anytime and anywhere, and can also respond quickly to abnormal situations and allocate resources.

[0048] In some other embodiments, the unattended lightning arrester test system further includes: The personnel management module can separate permissions and isolate data for personnel in various roles such as administrators and operators to ensure data security Permission access control: the background provides two-level permission verification management for functions and data, isolates sensitive data, and relevant personnel can only see data related to their work, ensuring the security of test data.

[0049] Independent networking, building a private visual integrated management and control system, various signal sources, display devices, audio devices, peripheral devices, etc. are virtualized in the cloud, and input and output control scheduling and other applications are implemented on the terminal; ordinary input nodes and office network PCs are only connected through video cables, which are completely physically isolated and have no risk of leakage.

[0050] In an optional embodiment, in order to better manage and monitor the arrester test equipment on the PC and APP, the laboratory remote management system may include: The laboratory management module is used to manage the laboratory where the arrester test equipment is located. Users can flexibly add and modify it according to the actual situation on site; The equipment management module is used to manage the information of all lightning arrester test equipment, including equipment ID, equipment name, equipment category, description, model, activation date, manufacturer, etc.
