0ã€Preface Baoshan Campus of Shanghai University is located at 380 Nanchen Road, Baoshan District. The total construction area of ​​the project is 133,500 square meters, of which the aboveground construction area is 120,000 square meters and the underground construction area is 13,500 square meters. Newly built mechanical automation, material literature, law and other college rooms, general-purpose laboratories, libraries, school administrative rooms, logistics supporting ancillary rooms, underground civil air defense projects and garages, and outdoor overall supporting projects.
This system can carry out 24-hour real-time automatic inspection on the working status of fire doors, and give alarm indications to fire doors in abnormal conditions. In the event of a fire, the monitoring system automatically shuts down the normally open fire door to gain valuable time for fire rescue and evacuation.
1. System Requirements Analysis The state of the fire door is detected and an audible and visual signal alarm is issued to accurately report the position of the fire door in an abnormal state. Store various fault alarms and other signals to display system power status.
2. Reference Standard GB29364-2012 Fire Door Monitor
GB50116-2013 "Fire Automatic Alarm System Design Specification"
GB50016-2014 "Architecture Design Fire Prevention Code"
GA93-2004 Fire Door Closer
3. System Structure AFRD100 fire door monitoring system centrally controls the working status of its terminal equipments, ie electric door closers and electromagnetic releasers. It can monitor the opening, closing and fault status of the fire exit doors of the evacuation passages in real time and display the open circuit and short circuit faults of the terminal equipment. signal. The system adopts the fire-fighting bus to connect monitoring modules with communication functions. When the terminal device is short-circuited or circuit-breaking, the fire door monitor can send an alarm signal, can indicate the alarm location and save the alarm information.
The three phases of the expansion of Baoshan Campus of Shanghai University are divided into three parts: the School of Materials and Communications, the Institute of Self-University and the Library.
The School of Materials and Communication mainly includes three areas: School of Materials, School of Communications, and General Laboratory. There are a total of 1 fire door monitoring host and 31 dual-door normally closed fire door monitoring modules.
The Institute of Mechanical Engineering includes three areas: the East Building, the South Building and the North Building. There are a total of 1 fire door monitoring host, 4 double-leaf normally open fire door monitoring modules, and 67 double-fan normally closed fire door monitoring modules.
The library section mainly includes 8 areas, including library, foreign language college, China-European college, liberal arts college, law school, social college, social science college and microstructure research center.

4, system function
System operation main interface
Consisting of four parts: “Login†button, “Interface Titleâ€, “Feature Listâ€, and “System Status Barâ€, you can quickly query the current monitoring status and can also be used for staff login operations.
User login interface
After inputting the correct user name and password, the system status bar will directly jump to the current user's operation interface, and the current login user and function list may be displayed.
Rights Management Interface
The interface is provided with three operation levels. The operation permission levels are "super administrator" → "administrator" → "operator", in which the high level can add low-level new users.
Condition Monitoring Interface
The interface graphically displays the working status of the currently monitored fire door visually. After clicking the fire door icon, the system displays the detailed information of the fire door.
Equipment testing interface
This interface can directly view and set some system operating parameters, and independently test some functions of the monitor, but only the "administrator" and above have the right to operate.
Event record interface
This interface can display currently stored alarm records, fault records, and event records. You can choose to query the same day records or customize the query date.
5. Concluding remarks With the rapid development of economy and science and technology, the concentration of people in the city is constantly increasing. When a fire occurs, the fire source is quickly isolated, and the scope of fire is effectively controlled. This can create favorable conditions for fighting fires and evacuation of people. Therefore, fireproof doors and other fireproof partitions are widely used in the firefighting design of construction projects. However, because of their unreasonable design, improper selection, and inadequate monitoring, fire doors cannot fully exert their isolation. Therefore, real-time monitoring and control of the working status of fire doors is an important measure to prevent the spread of fire and the proliferation of smoke, so the fire door monitoring system came into being.
Fire door monitoring system is a new type of product in the field of fire safety. It integrates industrial computer technology, communications, anti-electromagnetic interference, digital sensor technology and industrial field bus control technology in one intelligent system, can work on the status of fire doors for 24 hours Real-time automatic patrols, giving warnings for fire doors in abnormal conditions. In the event of a fire, the monitoring system automatically shuts down the normally open fire door to gain valuable time for fire rescue and evacuation.

The so-called portable projector, also known as pocket projector, mainly through the 3M LCOS RGB three-color projector and decoding technology, the traditional huge projector is compact and portable, making the projection technology closer to life and entertainment.
Advantages compared with traditional projectors:
1. Small size, light weight, easy to carry.
2. Low calorific value and low noise.
3. The price is relatively cheap.
4. Most models support wireless connection through software projection.
Applicable fields:
1. Replace some functions of TV: some machines can have built-in CMMB function, or can be directly connected to the set-top box to put TV, which can be used as a 21-inch TV during the day and a 60-100-inch TV at night (Note: Because of lumen and resolution issues, lumens during the day If the degree is not enough, it must be projected at a close distance) to achieve the effect of home theater; it is convenient to move and break through the traditional film and television space. Even if you are on the mountain, you can also share today's TV series, movies, and MTV with your lover.
2. Business trip: Portable projectors are easy to carry because of their small size and light weight. When you need to display computer content or mobile phone content, you only need to connect the portable projector to achieve the demonstration effect.
3. Private space: For dormitory beds or small private spaces, in the absence of a computer, you can use a portable projector to project the content of your mobile phone to watch video pictures, etc., without staring at the mobile phone at close range.
