[0026] Example:
[0027] like figure 1 The shown converter station misoperation prevention auxiliary system based on two-dimensional code identification is characterized in that it includes two-dimensional code labels set on all equipment related to switching operations in the converter station, and is used in conjunction with two-dimensional code labels The job item module, and the device status setting module used in conjunction with the job item module, and the device interlocking logic judgment module used in conjunction with the device status setting module, and the Android and ios used in conjunction with the device interlocking logic judgment module The client APP, and the computer used in conjunction with the client APP, and the field device status setting module information input module used in conjunction with the computer, and the reporting data module used in conjunction with the field device status setting module information input module, report data The information reported by the module includes the time when the on-site operator operates the equipment, the name of the equipment, the operation sequence, and the information of the on-site equipment status setting module.
[0028] Among them, the equipment interlocking logic judgment module can judge whether the equipment information and operating conditions are satisfied according to the data of the on-site equipment status setting module. If the conditions are not met, the alarm information will be displayed on the mobile phone display, and the operation project module will be imported and operated by personnel in the computer system. The mobile phone client includes Android and ios clients. The system has high adaptability. The operating personnel operate the on-site equipment in sequence according to the operation process. The reporting data module will report the on-site operation time, equipment, Personnel and other data are uploaded to the computer background system in real time through WiFi or 4G, and the equipment status setting module uploads the on-site equipment status setting module to the database by the on-site operators.
[0029] The present invention provides a co-working method for a converter station misoperation prevention auxiliary system based on two-dimensional code identification, including the following steps:
[0030] S1. First, install a two-dimensional code label on each equipment that needs to be operated in the converter station. The label contains a unique code that can accurately identify each equipment. At the same time, the two-dimensional code electronic label is connected with the field equipment in the system background bind, and define two states for each device;
[0031] S2. The operator of the converter station goes to the site with a smart phone installed with the system APP to check the information of the current equipment status setting module in turn, and confirms the current status of the equipment through the equipment status setting module, for example, in the "point" position, or " close" bit, generate device status setting module information library;
[0032] S3. When it is necessary to operate the equipment in the converter station, input the operation sequence information of each equipment in the operation ticket into the converter station misoperation prevention auxiliary system based on the QR code;
[0033] S4. The operating personnel use the mobile phone to scan the QR code installed on the device before going to the device according to the operation ticket information. The system will record the reading time of the label, and at the same time, the background of the system will automatically confirm the device information. When they are consistent, the system will pop up a permission operation command, and the on-site operation and maintenance personnel can start to operate the equipment. When the on-site equipment information is inconsistent with the equipment information that needs to be operated in the system, the system will prompt a notice to suspend the operation.
[0034] Workflow: Based on the two-dimensional code-based anti-misoperation auxiliary system of the converter station, the operator first enters the information input module of the on-site equipment status setting module, and enters the information of each equipment that needs to be operated in the converter station and its status and location information to the computer In the background of the system, when it is necessary to operate the equipment, the operator first imports the operation process between each equipment, that is, the operation ticket into the computer system, and the computer system sends it to the mobile phone client, and the operator follows the operation process instructions to scan before the equipment The QR code of the device, the background of the system automatically judges the device information and whether the device meets the operating conditions; if the device information is incorrect, it will prompt that the device information is incorrect on the mobile phone screen, please verify the device; if the device information is correct, but does not meet the device operation requirements If all the conditions are satisfied, the alarm will prompt to suspend the operation; if all the conditions are met, the prompt can be operated. After the operator finishes operating all the equipment, the system background will automatically generate records of the operator's operation process, operation time and current status information of the equipment.
