| The core thought of the fire alarm system is that it can apperceive any situations of fire in time and send the information to the center of monitor or linkage handle. Right because of this, the fire alarm electron figure monitor system. mentioned in this paper is designed basing on this thought and ,technically, the theory of serial port communication of the computer as well.The summary is as follows:The fire alarm electron figure control system consists of designing module and running module. The interface of the system is completed in the designing module, according to the request of the system devise some functions, such as print, print preview and so on. The running module is made from the server of database and many displaying terminal. The server consists of center database and background communication. The center database is the core in the system, it's tasks are as the follows: the displaying terminal manipulate the database, triggering the background communication module, when the background communication send the information to the controller. The information written by the controller are handled by background communication module to get the detail data that is inserted the database. The displaying terminal check the data inserted in the database if they are updated all through, if the data is updated, the information modified is displayed in the screen(like the situation has happened fire), the manager take the corresponded measure to deal with the case. The background communication is the bridge between the center database and controller. It's task are as the follows: repeating check the controller, including fire happened and fault appeared and the status of all apparatus. Receiving the information from the center database and encapsulating the data and sending the command to the controller. Receiving the information form the controller, parsing the information from and inserting the data into the center database. |
