Description
Technical Field
The invention relates to an internal and external disconnection detection and processing method of a centralized smoke exhaust system of a building.
Background
The range hood that uses in the kitchen of house and apartment at present, most all are independent separately, do not have the relation between the range hood of different residents, the user installs by oneself and inhales oil smoke and has very big randomness, most users directly set up the discharge port of range hood at the window trompil or the wall body hole digging in kitchen, the oil smoke directly discharges from the outer wall, cause the pollution interference to upper and lower floor resident family, and can cause oil pollution to the outer wall, can also influence the whole outward appearance image of building simultaneously.
With the rapid development of economy, more and more high-rise residences pull out the ground like spring shoots after rain. In order to keep the appearance of the whole building, a centralized smoke exhaust system of the building is adopted to perform centralized smoke exhaust in a plurality of high-rise civil residences, the system comprises indoor smoke exhaust ventilators arranged in kitchens of different residents on different floors, a public flue arranged in the building and an outdoor main fan system arranged on the top layer of the building, an air outlet of the indoor smoke exhaust ventilator is communicated with the public flue through an angle-adjustable electric check valve, and an air outlet of the public flue is communicated with an inlet of the outdoor fan system. The outdoor main fan system is often connected with the cloud server in a communication mode, and some indoor range hoods can also be connected with the cloud server in a communication mode.
In the centralized smoke exhaust system of building, data allocation and data summarization, system control operation mostly rely on outdoor main blower system, in case the outdoor main blower system just leads to the data of unable accepting indoor range hood easily to module faults such as the loRa of intercommunication, in case the 4G module fault of external communication appears will lead to unable state information that reports to the high in the clouds server, whole system loses the connection, the appearance of this type of disconnected condition has serious influence to system control and service monitoring maintenance in advance, and then influences actual experiences such as user oil absorption cigarette effect, noise.
Disclosure of Invention
The invention aims to solve the technical problem of providing an internal and external disconnection detection and processing method of a centralized smoke exhaust system of a building in view of the prior art.
The technical scheme adopted by the invention for solving the technical problems is as follows: a building centralized smoke exhaust system internal and external disconnection detection method is disclosed, wherein the building centralized smoke exhaust system comprises M indoor smoke exhaust ventilators arranged in kitchens of residents on different floors, and M is a natural number; the system comprises a public flue arranged inside a building, an outdoor main fan system arranged on the top layer of the building and a cloud server; the air outlets of the M indoor range hoods are communicated with a common flue through indoor air outlet branch pipes; m indoor suction ventilator and outdoor main fan system communication connection, outdoor main fan system and high in the clouds server communication connection, its characterized in that: the cloud server judges whether the indoor range hood and the outdoor main fan system are disconnected or not by the following method:
step 1, sending self state information to an outdoor main fan system by the M indoor range hoods at regular intervals;
step 2, the outdoor main fan system reports the state information of the outdoor main fan system and the state information of all indoor range hoods to a cloud server periodically;
step 4, judging whether the outdoor main fan system is disconnected, if so, finding out other outdoor main fan systems which are adjacent to the outdoor main fan system and are on-line, taking the found other outdoor main fan systems which are adjacent to the outdoor main fan system and are on-line as temporary outdoor main fan systems, and carrying out temporary handshake connection with the M indoor smoke absorbers; if not, entering step 5;
step 5, judging whether all the M indoor smoke exhaust ventilators are disconnected, if so, finding out other outdoor main fan systems which are adjacent to and online with the outdoor main fan system, and taking the found other outdoor main fan systems which are adjacent to and online with the outdoor main fan system as temporary outdoor main fan systems to be temporarily connected with the M indoor smoke exhaust ventilators in a handshaking way; if not, only part of the indoor range hoods are disconnected, and the system maintains the current situation.
As an improvement, in the step 3, if the state information of the outdoor main fan system and the state information of all indoor range hoods periodically uploaded by the outdoor main fan system are not received for more than two times or three times, the cloud server judges that the outdoor main fan system is disconnected; and if the self state information of the range hood in one room is not updated for two or three times in succession in the self state information periodically uploaded by the outdoor main fan system and the state information of all indoor range hoods, the cloud server judges that the indoor range hoods are disconnected.
And 5, finding out a plurality of other outdoor main fan systems which are adjacent to and online with the outdoor main fan system, and selecting the other outdoor main fan systems which are connected with the outdoor main fan systems and have low turn-on rate or high signal to noise ratio as temporary outdoor main fan systems from the plurality of other outdoor main fan systems which are adjacent to and online with the outdoor main fan system.
Compared with the prior art, the invention has the advantages that: whether the indoor range hood and the outdoor main fan system are disconnected or not can be detected in real time, and the outdoor main fan system close to idle is utilized to automatically act as a temporary host during disconnection, so that the intelligent control system has high intelligence and automatic checking capability, and no additional cost is required to be added.
