Smoke detector and communication method based on automatic addressing mode

Abstract

The invention relates to the technical field of detector communication, more particularly, to a smoke detector based on an automatic addressing mode and a communication method. The smoke detector includes a fire controller FSDCU and n detectors FSD. The fire controller FSDCU and the detectors FSD each are provided with a port CAN#0 and a port CAN#1. The ports CAN#0 and the ports CAN#1 all have the function of receiving and transmitting a frame address. The fire controller FSDCU and the n detectors FSD are connected in sequence. The fire controller FSDCU and the adjacent detectors FSD are connected through independently set CAN buses and the adjacent detectors FSD are connected through independently set CAN buses. Each detector FSD is provided internally with a data transfer module. The received command frame addresses can be subjected to increment or decrement operation through the data transfer modules to distinguish the CAN frame addresses of the detectors. When the detectors receive CAN frames of different addresses, addresses of response frames are also different, the process of address encoding of the detectors is eliminated, and the system configurability is enhanced.

Description

technical field [0001] The invention relates to the technical field of detector communication, in particular to a smoke and fire detector based on an automatic addressing mode and a communication method. Background technique [0002] The high-speed EMU is a highly integrated manned tool with fast movement speed and complex structure. Its electrical equipment is varied and the space is airtight. Once a fire occurs, if it is not discovered in time, it will be difficult to take corresponding measures in time, which will cause greater casualties and property losses. Therefore, it is of great significance to invent a safe and reliable high-speed EMU pyrotechnics online monitoring system. [0003] The number of detectors on the train changes with the demand, and the number of detectors on each vehicle type and car is not fixed, so the pyrotechnic system should be designed as a flexible system that can adjust the number of detectors at will. A type of system where redundancy of ...

Problems solved by technology

That is to say, although the above-mentioned controller and the detector and the detector and the detector are connected by an independent CAN bus, each detector still needs to set an independent address to identify the corresponding detector, which affects the configuration flexibility.
