1. Project background
With the progress of society and the application of various scientific and technological means, we are deeply benefiting our human society. Until today, the application of electric energy can no longer be separated from our daily life. With more and more power grids, the application of electricity to our lives has become The more we come, we may not know how to live without electricity.
If there is a sudden power failure, on a large scale, the industries that require electricity to operate cannot operate, which will bring huge losses to the country to the enterprise. Even if the household rice cooker cannot work, even eating may be a problem, and the longer the failure time will be. Longer, the greater the loss, even immeasurable. As for the inspection of power stability, emergency repair is inevitable when there is a fault.
When the power engineer is performing emergency repairs, he may not have a good understanding of the tool information. It is possible that a piece of electrical equipment has reached the point of being scrapped and damaged, but during the repair process, because such a repair tool cannot be used normally, the repair delay is caused. , Or after the emergency repair construction, the engineer unconsciously loses the emergency repair tools, equipment, etc. For the next emergency repair lack of tools, the implementation of the emergency repair work is more difficult, the repair progress is delayed, and losses are caused. This is what we often say because of small losses.
After decades of development, RFID has been widely used in various industries and is infiltrating into various traditional industries, such as asset information processing, real-time tracking of information product information, etc. Many companies can realize asset management and inspections automatically, real-time and intelligently by combining RFID tags with products.
At present, RFID technology has gradually become an indispensable technology and management method for units and enterprises such as State Grid, telecommunications, Internet of Things, etc., to improve asset system management, reduce management costs, enhance service capabilities, and improve work efficiency.
RFIDTechnology can be informatized from asset tools, delivery, distribution, requisition, delivery, warehousing, and loss prevention, providing users with real-time dynamic tracking and query throughout the process; realizing the monitoring and management of processing information, system operation status, and business operation. This can solve a series of problems caused by the incomplete construction of information intelligence. Effectively reduce the management cost of the quality system, enhance the corporate reputation effect, and improve the industry’s market service capabilities.
2. Program objectives
In view of the above situation, it is necessary to add an on-board equipment management system to realize the digital management of tools and common materials, and to manage the real-time conditions of tools, equipment, and equipment on the vehicle by pasting, installing, and hanging RFID tags to reach the equipment on the vehicle. The purpose of leaving the factory, putting into use, adding, leaving idle, scrapping, repairing, inventory, access management, alarm setting, annual inspection validity period management, etc. of assets. After the electronic tag is installed, the information of the asset is written in the tag. Every time the asset management operation is performed, the reader will read the electronic tag on the asset and send the information to the on-board industrial computer server for processing, thereby realizing asset management. Tracking management.
1.21 Accurate tool number ID
Use the RFID tag to bind the tool, write asset information in the tag, and accurately number the tool ID.
1.22 Strengthen the accuracy of tool asset information
The real-time status of the equipment is managed to achieve the purpose of leaving the factory, putting into use, adding, idle, scrapping, maintenance, inventory, access management, alarm setting, and annual inspection validity period management of equipment assets on the vehicle. After the electronic tag is installed, the information of the asset is written in the tag. Every time the asset management operation is performed, the reader will read the electronic tag on the asset and send the information to the on-board industrial computer server for processing, thereby realizing asset management. Tracking management.
1.23 Prevent loss when entering and exiting the warehouse
Due to the emergency repair time and other human factors, the tool cannot be returned in time, or the tool is lost during the emergency repair process, it is necessary to solve the problem of tool loss prevention.
Three, system architecture
According to the design characteristics of RFID tags, through the implementation of power emergency repair tool management, outbound and inbound information management systems, and key elements and key technical processes in the electronic emergency repair of vehicles, a security information system management based on RFID technology is proposed. Through RFID technology, all links of power out of the car, out of the warehouse, warehousing, and real-time informatization of tools are organically integrated to save manpower, save costs, prevent loss of tools, and incomplete tool information that cannot be managed in a unified manner. Integrated information management.
When planning and designing, it is necessary to consider the real-time and accurate data collection, the massive data processing of each node, and the concurrent processing issues to ensure the stability and accuracy of the system, as well as the conflicts with other software. System interface requirements and remote data information communication requirements.
Fourth, the program operation process
(1) System operation:
1. Set the first-level server, and enter the task location and task name by the client when the task needs to be repaired.
2. An engineering vehicle-mounted engineering computer is installed in the tool cart. When a task is issued, the task can be downloaded from the industrial control computer.
3. The card reader device connected to the vehicle-mounted industrial computer and the vehicle-mounted engineering computer store all the data information of the vehicle-mounted tools.
When the emergency repair starts, the emergency repair engineer needs to perform electronic registration (via the on-board engineering computer), and select the task that currently needs emergency repair after registration.
4. Control the computer to start the emergency repair task project, and automatically start the emergency repair timing.
5. At the same time, the card reader is automatically run for tool scanning. The card reader will scan the whole car every 10~30 (settable) milliseconds. When the device is read for five consecutive times or within 10 seconds, it is bound to the device The system automatically judges that the tool is loaded in the car, and the label is not read for more than 20 seconds. The industrial computer will automatically generate outbound reports. The report contains the time of acquisition, the repair project, the name of the repair engineer, the number of the tool used, and the tool information.
6. When the repair engineer completes the repair and returns the tool, the card reader will automatically read the RFID tag of the returned tool. When the returned tag is read within 10-20 seconds, the industrial computer program automatically judges that the tool is returned. The generated log is returned to the warehouse for the requisition tool.
7. When the emergency repair is completed, it is necessary to confirm the completion of the emergency repair on the industrial computer. If any tools are not returned in time, the industrial computer program will give an alarm and fail to submit the task for successful completion of the emergency repair.
8. If the tool is lost at this time, you can use the handheld terminal to search for the tool on the construction site. When the tool is retrieved and loaded into the car, the alarm will automatically stop and the tool will be regarded as being stored.
9. When the industrial computer is handed over after the emergency repair is completed, the industrial computer will automatically upload the task record to the first-level server for archiving for review.
(2) Binding tool label
Choose UHF RFID tags, anti-metal tags, and tags that combine the tags with repair equipment tools, such as stickiness, suspension, screws, etc.
After the RFID tag is combined with the tool, the information needs to be entered into the computer and the tag tool software is bound.
2.32 Label initialization
The RFID blank tag itself does not represent anything, so the first task of the RFID application system is to associate the RFID tag with a unique ID number with the actual item one by one, and associate the ID identity of the tag with the identity of the tool. After binding, each tool has its own unique identity. In the subsequent process, the relevant information of the goods can be obtained by reading the RFID tag information, so that the information flow of the entire system can be transmitted through the RFID tag. .
The following is the software operation flow of writing materials into the chip:
(3) Label data management
The label tool data is entered into the workbench from the emergency repair information and entered into the server database. The new tool will also be entered into the server. When the new tool is allocated, the new tool can be allocated on the server side to each number of emergency repair vehicles. The industrial computer inside will download and update the tool database.
