Problems solved by technology

However, the signal strength of the existing wireless communication local area network is relatively unstable. In different environments, the signal strength will change. Therefore, according to the preset number of floors at intervals, the method of uploading information in the form of jumps cannot guarantee information Upload Stability and Reliability

Embodiment Construction

[0045] The following examples illustrate the invention, but the invention is not limited by these examples. Modifications to the specific implementation of the present invention or equivalent replacement of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed in the present invention.

[0046] Please refer to figure 1 , the present invention provides an information transmission method for a smoke collection and exhaust machine, including an information uploading method, and the information uploading method includes the following steps:

[0047] S1: Update the routing table information of the local child nodes on each floor, so that the master node obtains the information of the nearby floor child nodes that the local child nodes can receive the heartbeat signal. The information of the nearby floor child nodes includes the number of floors where the nearby floor child nodes are locat...

Abstract

The invention discloses an information transmission method of a smoke collecting and discharging machine and the smoke collecting and discharging machine, the information transmission method of the smoke collecting and discharging machine comprises an information uploading method, and the information uploading method comprises the following steps: S1, updating local child node routing table information of each floor, the heartbeat signals can be received by the local child nodes, and the information of the nearby floor child nodes comprises the number of floors where the nearby floor child nodes are located and signal intensity information of the nearby floor child nodes; s2, whether the absolute value of the difference between the number of floors where local child nodes are located and the number of highest floors where child nodes of nearby floors are located is larger than or equal to M or not is judged, if not, information of the local child nodes is uploaded to the child node of the N1th floor, and if yes, S3 is executed; and S3, judging whether the local child node detects that the main node is online and the signal strength of the main node is less than Kdbm, if so, uploading the information of the local child node to the child node of the N2 layer, and if not, uploading the information of the local child node to the main node.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to an information transmission method of a smoke collection and exhaust machine and the smoke collection and exhaust machine. Background technique [0002] The collection and discharge hood system relies on wireless communication LAN to transmit information. Existing collection and exhaust smoke machine systems generally use sub-node intervals to preset floors, and upload information to the main node in a jumping manner to increase the upload speed of information. However, the signal strength of the existing wireless communication local area network is relatively unstable. In different environments, the signal strength will change. Therefore, according to the preset number of floors at intervals, the method of uploading information in the form of jumps cannot guarantee information Stability and reliability of uploads. [0003] Therefore, there is an urgent need for an i...
