1 Application background
Fire-fighting equipment management is a very important task for firefighting forces. To continuously improve the efficiency of the use of inherent fire-fighting equipment, it is necessary to strengthen the supervision and management of inherent fire-fighting equipment. Since the types and quantities of unit equipment are relatively large, the value is relatively high, and the service cycle is relatively long, these characteristics make the unit face many challenges in the management of inherent fire-fighting equipment, such as: inaccurate depreciation data of inherent equipment, inaccurate book value statistics, Problems such as heavy inventory work and missing equipment have seriously affected the operational efficiency of the unit, resulting in repeated purchases of equipment, resulting in a substantial increase in costs. Although some units have fully realized the importance of inherent firefighting equipment management, the management of inherent equipment is very complicated, even with the support of the management system, the formulation, filling or printing, pasting of inherent equipment labels, tracking of asset status, The nature and workload of inventory and other tasks have not been well changed and improved.
Judging from the current status quo, 1. The agencies of various localities, levels, military and local governments have put forward higher requirements for the management of inherent equipment; The importance of inherent equipment management requires more advanced technical means to make up for the deficiencies of existing technical conditions. The core problem of orderly management of inherent equipment lies in the automatic collection of information in the previous stage. At this time, the automatic identification technology during World War II It has received extensive renewed attention-wireless automatic identification technology (abbreviated as: RFID), more and more people are beginning to pay attention to the function and practicality of RFID, and R&D personnel have successively developed generations of stable performance that can meet a variety of needs Information collection equipment and information storage equipment, which makes the use of RFID quickly expanded to various fields. In the management of inherent equipment, RFID plays a very important role. RFID technology can make the management of equipment easy and simple, avoiding Data errors and time consumption caused by manual operation and recording.

The overall plan of the fire-fighting equipment warehouse
3.1.1 Description of the general plan of warehouse fire-fighting equipment
The actual number of readers are installed on the top of each fire-fighting equipment warehouse according to the actual size of the space, and the electronic tags are installed on each fire-fighting equipment. The readers receive the electronic tag data in real time and transmit the information collection time, type and quantity of fire-fighting equipment, etc. To the single-warehouse management center, all warehouse management centers then summarize the information to the back-end management center. The back-end management center can also set the authority of single-product fire-fighting equipment and the same type of fire-fighting products. The fire-fighting equipment without the approval of the leader is out of the warehouse privately or the fire-fighting equipment is taken out due to the negligence of the firefighters and installed in the background management or at the door of the warehouse. The alarm will activate the relevant alarms to remind the relevant responsible persons to make up the relevant procedures for leaving the warehouse; in addition, the leaders of each department can check the type and quantity of the warehouse fire-fighting equipment at any time according to their actual authority, and can print the report at any time.
3.1.2 Real-time supervision system function of fire equipment warehouse
1) Real-time inventory of fire-fighting equipment in the warehouse. Leaders at all levels of the unit can grasp the number, type, time of exit and entry, and the trend of fire-fighting equipment in the warehouse in real time according to their scope of authority;
2) For fixed equipment such as fire-fighting equipment in the warehouse, permissions can be set, and only legally authorized fire-fighting equipment can enter and leave the warehouse. For non-authorized fixed equipment, bring out the background without asking for instructions and immediately call the police. Arrive at the indicated location quickly to deal with related incidents;
3) Ensure the safety of fire-fighting equipment, prevent criminals from theft or negligence of fire-fighting equipment taken out of the work site, causing unnecessary economic losses to the unit;
3.1.3 The composition of the real-time supervision system of the fire-fighting equipment warehouse

5) 2.45G long-distance active electronic tag (special tag for positioning, a variety of sizes are available, read-only type);
6) Alarm controller (the monitoring room controls the alarm device);
7) Alarm (start the alarm if there is an abnormal situation, install it near the warehouse access control and the monitoring center);
8) Network switch (RJ45 network interface reader access)
9) Computer
10) Server
3.1.4 Networking configuration of fire equipment warehouse
Because the management of fire-fighting equipment is an integrated system, and the warehouses are located in different areas, different identification base station antennas are used to realize the access detection of the fixed equipment of each warehouse, so it is necessary to install and configure the identification base stations and the identification base stations in different warehouses. The monitoring machines are connected to the network, and the real-time monitoring data detected by the identification base stations are collected in the same platform system, and the sound and light alarms in the corresponding warehouses and management centers are triggered in real time. At the same time, the unified configuration of the fire protection intelligent management software is used for centralized management. Various basic data.
According to the actual equipment selection, the identification base station is connected to the Ethernet network with the Ethernet interface interface, so that the wireless identification system between the warehouses can be networked through the existing Ethernet network to form a unified platform for centralized safety management provide assurance.
