1 General overview

Ensuring the safety of electric power production is the most important work content of electric power enterprises, and this work is undertaken by a special electric power safety supervision department. An important responsibility of power safety supervision and management is to strengthen the management of power safety tools and equipment to ensure the safety, inventory management, and use supervision of tools and equipment, especially in relation to the "two tickets" (ie work tickets and operation tickets). Used in conjunction to standardize power production safety measures, improve power production safety guarantees, and establish corresponding safety precautions and preventive measures for this purpose.

At present, power safety supervision and management is mainly based on manual management, supplemented by preliminary computer information management, mainly including "two votes", "two measures" and other content, but lacks real-time monitoring of safety tools and instruments, and the "two votes" "Supporting monitoring and management methods, therefore, it is impossible to discover potential safety hazards in power production in time. The power safety monitoring and management based on manual supervision and post-event summary can no longer meet the requirements of prevention and real-time monitoring in power safety monitoring and management in modern enterprises. Requirements.

The system uses the most cutting-edge technology, RFID radio frequency identification technology combined with intelligent temperature and humidity control, to achieve intelligent management of the warehouse. The system can realize unmanned tool room management, support automatic identification of tools and equipment and personnel entry and exit, the system automatically records the RFID information of the person responsible for the acquisition of tools and equipment, and can display real-time information about the acquisition of tools and equipment in the library and related information of the responsible person when it is started It can also remind the person responsible for the test date to expire the test.

To this end, with the Safety Supervision Department as the center, the establishment of a networked chemical equipment monitoring and management system covering branches, power supply stations, and substations to the users will surely improve the safety supervision of electric power companies from the aspects of digitization, electronics, and networking. Management level.

3.1.2 Tools and equipment monitoring methods

There are many ways to classify the safety tools and instruments of power supply companies, such as: according to the type, physical location, and status of the tools and instruments. In order to better combine the actual work needs of users and further explain our technical solutions, we will distinguish the tools and appliances by the physical location of the tools and appliances, and use different monitoring methods for the tools and appliances stored in different locations. In order to monitor tools and equipment more clearly and reasonably. According to the storage location, tools and equipment are mainly divided into: tools and equipment stored in the tool and equipment cabinet (referred to as the tool in the cabinet), stored on the tool rack, including video surveillance, personnel access, and indoor environment detection (referred to as indoor Appliances), tools and tools used or to be used by the construction team (referred to as tools outside the cabinet).

Monitoring method of tools and appliances in the cabinet:

1. Tools and equipment that have a greater impact on production safety:

We use real-time monitoring for this kind of tools, and we will introduce this method in detail in the following introduction.

2. Appliances that have less impact on production safety:

This type of tool has a relatively small impact on safe production. In order to save costs, we use barcodes on the tools (barcodes are the unique asset numbers of the tools), and collect data through a handheld smart terminal. The same as the cabinet we will introduce below The monitoring of external equipment is consistent. For details, please refer to the introduction of monitoring equipment outside the cabinet.

Monitoring method of tools and instruments in the warehouse:

Record the entry and exit status of all personnel and the entry and exit status of equipment through a combination of cameras and access control systems. Stored on the safety tool rack, the equipment can be monitored in the form of RFID tags.

Indoor environment, through the intelligent environment to identify temperature, humidity, etc., fixed values can be set freely or manually controlled. Taking the fixed value as an example, when the indoor environment exceeds the fixed value range, the system will automatically start dehumidification and heating equipment according to the situation. Ensure that the warehouse works in a permitted environment.

Monitoring method of equipment outside the cabinet:

In addition to the online GRPS monitoring, the on-site operation monitoring method also supports the offline method. The handheld smart terminal uses the latest tool library downloaded when online as a standard for testing.

The operation process is as follows:

1. Use a bar code printer to print bar codes, each bar code has a unique number to ensure the uniqueness of tools and instruments in the system;

2. The barcode has been affixed on the tools and tools before the construction team leads the tools;

3. The inspector uses a handheld smart terminal to scan the information on the barcode, and upload the read information to the database via GPRS. GPRS is the abbreviation of "General Packet Radio Service" (translated as "General Packet Radio Service"). It is a set of wireless transmission methods developed by the concept of "Packet Switching". The so-called "packet exchange" is to encapsulate data into many independent packets, and then send these packets out one by one. The form is somewhat similar to sending parcels in a post office. See below:

4. The database feeds back the information required by the tools and equipment to the handheld smart terminal, thus realizing the monitoring and management of the tools and appliances, for example: when the returned tool and equipment information is unqualified, the inspector will deal with it in time to ensure the monitoring and management of the safety tools and equipment , To ensure the safety of power construction.

5. When a handheld PDA terminal is used for on-site monitoring operations, the labels of the tools and instruments are scanned through GPRS to obtain the information of the currently used work ticket and the number of the tools used. The safety supervisor can compare with the actual work ticket to judge the on-site operation Whether the tools and equipment are currently legal work tickets, providing more in-depth monitoring of the use of tools and equipment.

3.2 System application software

3.2.1 Application software system structure

The safety equipment monitoring and management system is built on the internal local area network of the power supply company. The entire system is based on the J2EE architecture, adopts the B/A/S three-tier structure model, and applies new technologies such as AJAX. It makes up for the shortcomings of the B/A/S model, balances the load of the application server and the client, and greatly improves the user experience of front-end and back-end information interaction operations and multi-category business data applications.

The whole system consists of three parts: the client of the safety tool and equipment monitoring management system, the communication monitoring platform, and the database server. The software architecture is shown in the figure below:

The communication monitoring platform includes a communication module and a short message module. The communication module is responsible for sending and receiving and data storage. The information collected by the smart terminal is sent to the database, and the database feeds back the corresponding data to the smart terminal. The client is the customer's monitoring and management of the entire tool and equipment, file query, business processing, statistical analysis, system management and other functions.

The database server includes basic information database and graphic data files.

3.2.2 Application software permission structure

Based on years of information system development experience and power industry software development experience, the company has designed and developed a scientific, controllable and rigorous authority management structure. This structure can solve the authority problem of most information systems.

The system authority structure is provided as a platform function, and the system provides a general authority management mechanism, which has nothing to do with any business. The control level of system authority management function is divided into three levels:

Function menu authority level

If the system operator passes the uniform application program, passes the operator identity authentication, the system displays the main interface of the system according to the function menu operation granted by the operator. Only the function menu that the operator has the right to use is displayed on the main interface of the system. Unauthorized functions are transparent to the operator.

Functional component layer

For the functions granted to the operator, the system provides further authorization: the operator is granted access to certain buttons and components on the page, and unauthorized buttons are transparent to the operator.

Data domain control layer

For the function pages that the operator can open, we control the data domains that the operator can access. Only authorized data domains can be modified by the operator. Unauthorized data domains can only be viewed and cannot be modified by the operator.

Authority management of system data area

The authority management of the system data area means that the operator can only operate the data in his own jurisdiction, and the data in other areas is transparent to the operator.

The system achieves the purpose of data area authority management through the authorization of the management unit. When the operator logs in, he will retrieve the list of management units that he can handle according to his identity. All functions with management area conditions provide the operator with his own authority The range of management unit selection makes it impossible for him to manipulate data beyond the scope of his authority.

For example: the relevant personnel of the branch can only view the information of the branch, while the head office can view the relevant information of each branch.

3.2.3 Application software functional structure

The system application software part adopts the DFC system structure accumulated by our company's long-term engagement in the integrated development of electric power information applications, and carries out software design with platform-based thinking, and builds the following application software platforms:

1. Function integration platform

2. Business process platform

3. Data dictionary platform

4. Information query platform

5. Statistical analysis platform

6. System management platform

When two tickets are issued, the corresponding list of types and quantities of tools and instruments that should be used can be generated in the system at the same time, so as to check and monitor corresponding to actual work.

3.2.6 Analysis of the combined use of "two votes" and tools

Combining the data of the two tickets and the usage of the appliances collected through this system, compare and analyze whether the safety tools and appliances are accurately carried in the process of the two tickets, and give the analysis results.

3.2.7 "Two Tickets" and Security Management of Access Control

According to the data interface with the two-ticket system, combined with the authority of the operator and guardian provided by the two-ticket system, the tool cabinet access control judgment is performed. The networked access card reader reads the card number information and sends the card number to the safety tool system. The basic card number is associated with the operator or guardian's tool cabinet authority to check the two votes and open the door.

It can be equipped with a switch for emergency opening of the door by the highest authority management personnel or using a super user card. The cardholder has the highest authority to open the door in an emergency. All door opening records are available in the system for detailed information, including opening time, Information such as door opener, cabinet number, work ticket number, etc. The security personnel have detailed files in the system, the access control RFID card number, and the personnel's security tools and equipment cabinet door permissions are registered in the detailed files, including their units, substations or power supply stations. The operator in the two-ticket system can correspond to the security tool and equipment system personnel. When the access control card is read and obtained, the card is reported to the networked tool and equipment system. The system combines the two-ticket system and its specified operating time range to make judgments and send unlock signals. Automatically open the corresponding tool cabinet door.

3.2.8 State monitoring of tools and instruments

Through the LAN, the monitoring center monitors the in-position status of various safety tools and instruments online 24 hours a day. When the status of the tools and appliances changes, it is automatically recorded in the database, the current status is automatically updated, and the status is displayed graphically on the large screen. If it is non-working time or set time, the status change can also be sent to the mobile phone of the manager through the SMS platform.

Real-time monitoring interface: 24-hour online monitoring of the in-position status of various tools and appliances. When the status of tools and appliances changes, it will be automatically recorded in the database, the current status will be automatically updated, and prompts will be given in graphical and voice alarm modes at the set time Inside, the status change can be sent to the mobile phone of the manager through the SMS platform. Combine with the "two votes" to analyze whether tools and equipment are properly equipped during construction
