Description
Technical Field
The invention relates to the technical field of fire fighting, in particular to a method for displaying multi-Chinese character position information on a fire display panel with low bandwidth.
Background
The fire display panel is a component of a fire alarm control system, is mainly used for displaying data transmitted by a fire alarm controller, is mainly installed in each floor, and is also called a floor display. When a fire disaster occurs in a corresponding fire protection subarea or floor, the fire disaster alarm controller receives the alarm information and simultaneously sends an alarm signal to a fire disaster display disc in a fire disaster occurrence area, the fire disaster display disc displays relevant information such as fire disaster information or faults, and the like, and simultaneously sends out sound and light alarm signals.
Because the communication bandwidth required for realizing the position description of the Chinese characters of the fire display panel is very large and the requirement on the passing speed is very high, the current fire alarm carries out signal transmission and power supply through two buses and needs to consider the reason of power supply, the bandwidth is very narrow. Therefore, most fire display panels on the market can not display Chinese characters at present, and can only display the loop and the address of the part triggering the alarm. Obviously, the display mode is not intuitive and not clear, and for non-professional personnel, the specific position of the fire or the fault cannot be known, so that the actual application requirement is difficult to be really met.
Based on the above, some manufacturers add a separate fire display panel management module to the fire alarm controller, use a separate high-speed communication line (such as CAN) and a 24V power line, and use four lines to separately communicate and supply power to the fire display panel. For example, patent publication No. CN1794307A discloses a fire display panel control system that uses a fire information converter to generate a dedicated line. Particularly, in the fire display panel management module, the fire information converter uses an RS232 serial port mode and a controller to perform short-distance internal communication (the communication distance of an RS232 serial port cannot be larger than 3 meters generally, and the speed cannot exceed 57600bps), and then the fire information converter generates a special line (CAN) and fire display panel communication. The mode basically solves the problem of multi-Chinese character display at present, but two lines are added, and the fire alarm system is also a special line, and can only be used by a fire display panel, and other intelligent components of the fire alarm system cannot be used, so that great inconvenience is brought to construction and maintenance, and the cost is high. Meanwhile, transmission instability CAN be caused by high-speed data packet transmission, the anti-interference capability is poor, the transmission distance of the CAN field bus in a high-speed mode cannot exceed 800 meters, and the transmission distance is limited. And branch wiring can not be carried out, a terminal resistor needs to be added, the requirement on the wire is extremely high, and popularization cannot be carried out, so that the wire is rarely used in the market.
Therefore, a multi-Chinese character display method for a fire display panel, which can display position information by Chinese characters, has low system design requirements, no time delay, and high reliability at a long distance, is needed in the field to fill the technical gap and improve the functions and performance of the fire display panel, thereby really meeting the actual application requirements.
