Example II
The embodiment discloses a transformer substation tool safety control method based on information classification storage, which comprises the following steps:
before the tools enter the transformer substation, a machine account is established and safety detection is carried out. The tool machine account, i.e. tool basic information, includes: the number of the tools, the names of the tools, the classification of the tools, the date of delivery, the unit to which the assets belong, the responsible person and the contact way, and the photos of the tools from different angles. The tool safety detection information includes: inspection time, inspection unit, inspector, safety inspection validity period deadline. The special marking information comprises special tool marking, tool defect or damage history records, defect or damage picture information, tool scrapping marking and the like. The information can be input in a background management system or generated by uploading through a front management terminal, and all the information is stored in a data server.
And binding the tools and the electronic tags after completing tool information input and storage in the background management system. The tool has a unique number, the electronic tag also has a unique code, and the tool and the electronic tag can be bound by binding the tool and the electronic tag. In addition, in order to facilitate field management and control of the tools, the background management system writes basic information of the tools, safety detection information of the tools and special marking information of the tools, except for pictures, into the storage of the electronic tag for reading by different types of reading terminals. The data in the electronic tag can be encrypted and protected, and other systems or terminals only allow the information to be read but not the information to be modified except that the background management system can modify the information in the storage area of the electronic tag.
The electronic tags are fixedly arranged on the corresponding tools. A class 2 reading terminal is arranged at an entrance of the transformer substation, and before the tools enter the transformer substation, managers check the tools by means of the class 2 reading terminal to ensure that the tools are registered qualified. And the reading terminal reads the electronic tag, acquires the detailed information of the tool stored in the electronic tag, displays the detailed information on a human-computer interaction interface of the front management workstation, compares the detailed information with the tool information issued by the background management system database, allows the tool to enter the transformer substation if the detailed information of the tool and the tool information are consistent, and prohibits the tool from entering the transformer substation if the detailed information of the tool and the tool information are not consistent.
The tools can be brought into the transformer substation by constructors after being checked and checked through inspection. In order to record the accurate time of entering/exiting the transformer substation of the tools, a class 1 reading terminal is required to be arranged at an entrance of a transformer substation construction site, and the terminal only reads the coded information of the electronic tags and the serial number information of the tools. Two reading terminals of the 1 st type are arranged at the entrance, the distance between the front and the back of the reading terminals is 50cm, and the reading terminals are respectively marked as a terminal A and a terminal B. If the terminals A and B detect the electronic tags in sequence, indicating that the tools enter the field; otherwise, if the terminals B and A detect the electronic tags in sequence, the fact that the tools are out of the field is indicated. The terminals A and B can record the detection time of the electronic tag, the electronic tag coding information, the reading terminal detection sequence information and the time information are sent to the preposed management workstation through the communication system, and the preposed management workstation generates the entry and exit records of the tool.
During work, a manager can check the detailed information of the tools at any time by using the portable handheld type class 2 reading terminal. A manager can quickly obtain complete information such as electronic tag coding information, tool basic information, tool safety detection information, tool special marking information and the like in an electronic tag storage area by using the handheld reading terminal only by approaching the electronic tag of the tool at a distance of about 10-30 cm, and then the complete information is displayed on a display screen of the handheld reading terminal. The handheld reading terminal can acquire and store detailed information of related tools from the background database, so that the accuracy and the effectiveness of the information of the tools can be judged on site, and when the tools do not conform to the information or the safety inspection is overdue, an alarm can be automatically given to remind a manager of paying attention.
If unexpected special conditions such as damage of the tool and the like occur in the construction process, a constructor or a manager can trigger the front management workstation to access the data server of the background management system by using the type 3 reading terminal, so that the information such as the text description information, the picture information of important parts, damage marks and the like of the tool and the tool under the condition of the damage or the accident is uploaded to the data server, and the front management workstation retreats the tool and does not allow the tool to be used continuously.
After the data server of the background management system receives the reported information of damage of the tool, scrapping of the tool and the like from the front-end management workstation, the reported information is processed by a special tool and the tool safety detection personnel. If the tool is damaged, whether the tool can be repaired is judged according to the damaged position and the damaged degree of the mark. If the tool and the instrument can be repaired, the safety detection is needed to be carried out on the repaired tool and the instrument are allowed to be put into use again through the safety detection, but the damage marking information in the database cannot be cleared, and the special marking information in the electronic tag is updated to indicate that the tool and the instrument have the safety problems such as damage and the like. If the repair is not necessary, the tool is scrapped, the marking is invalidated at the special marking information position, and the electronic tag is recovered.
If the tools and the instruments reach the service life or are seriously damaged and do not meet the requirement of continuous use, the tools and the instruments need to be scrapped. The scrapping treatment can be completed in a front management workstation or a background management system. Reading the coded information of the electronic tag and the serial number information of the tool by using a 3 rd type reading terminal, starting a front management workstation or a background management system to access a data server, submitting the scrapped text description information and picture information of the tool to a database after obtaining access permission, marking scrapping at a special marked information position, simultaneously withdrawing the electronic tag, unbinding the tool and the electronic tag by a manager in the front management workstation or the background management system, and deleting all information in an electronic tag memory. If the tool is scrapped but the electronic tag is still used, when the tool is checked before entering the transformer substation, the returned information from the database can prompt that the tool is scrapped and is inconsistent with the information stored in the electronic tag. Therefore, the hidden danger of safety management of tools and appliances caused by untimely recovery of the electronic tag can be avoided.
Important special areas such as a high-voltage live operation area, a data communication center and a protection control equipment room still exist in the transformer substation, and tools entering and exiting from the important areas need to be rapidly identified and tool entering and exiting records need to be formed. For the tools and instruments allowed to enter the important area, corresponding marks are made on the tool and instrument special marking information of the database through a front management workstation or a back management system in advance by a manager, and the permission marks are written into a storage area of the electronic tag to indicate that the tools and instruments are allowed to enter the important area of the substation. The method comprises the steps that a class 1 reading terminal is installed at an entrance of an important area in a transformer substation, the reading terminal only reads electronic tag coded information and special marking information, the electronic tag coded information serves as a basis for recording whether a tool enters or exits the important area (the mode of the A reading terminal and the B reading terminal is still adopted), and the special marking information serves as a basis for judging whether the tool has permission to enter the area.
A temporary safety control method is also provided for some tools which are not subjected to safety detection and registration in advance but are urgently needed for actual field work. And performing temporary detection on the tools and instruments by field management personnel, and issuing temporary electronic tags after the tools and instruments meet the requirements.
