Technical Field

Background

The "polling" refers to a method in which the host acquires data from the slave nodes in sequence in a roll call manner according to a plurality of addresses preset by the system, in other words, the "polling" is a manner in which the host queries one by one.

At present, traditional fire emergency light control system all adopts to carry out the polling to lamps and lanterns with the maximum address quantity (that is to say start at every turn and all roll call in proper order lamps and lanterns according to a plurality of addresses that the system is preset, following call is full polling), and the address quantity that the system is preset often is more than the lamps and lanterns quantity of actual access a lot of, consequently, the system often can pass through a plurality of blank addresses when carrying out full polling to the lamps and lanterns of access, not only system processing resource is wasted, also can consume a large amount of time simultaneously.

Too long polling time will cause that the evacuation plan of the emergency lamp control system cannot be issued in time, which causes serious consequences such as self-rescue delay of related personnel in emergency, missing of optimal escape time and the like.

In addition, because the full polling time of the emergency lamp control system is too long, not only the failed lamp cannot be located in time, but also the method of confirming the failed lamp through multiple polling is not suitable (because the full polling time consumption is too long, if each lamp adopts full polling to confirm whether the failure occurs or not, the polling time is increased by times, so that the problem of polling delay is more serious), thereby not only the failure of the failed lamp cannot be timely eliminated, but also the false alarm rate of the lamp failure is increased.

Therefore, the technical problems that the evacuation plan of the emergency lamp control system cannot be issued in time, the fault lamp cannot be positioned in time and the lamp fault false alarm rate is increased due to the fact that the emergency lamp control system adopts a full polling mode in the prior art exist.
