Embodiment Construction

[0031] Embodiments of the present invention will now be described with reference to the drawings, in which like reference numerals represent like elements.

[0032] figure 1 It is a schematic diagram of an embodiment of the wireless Andon system of the present invention. like figure 1 As shown, the wireless Andon system includes multiple information collection nodes 110 , a coordinator node 120 and a host 130 .

[0033] The plurality of information collection nodes 110 are respectively located at key positions of the production line that are prone to material shortage or failure, so as to collect production line information corresponding to key positions and send the production line information, such as production status, raw material status, and quality status As well as equipment status, this information can reflect whether the production line in operation has problems such as insufficient raw materials, equipment failures, etc. that cause the production line to fail to op...

Abstract

The invention discloses a wireless Andon system, which comprises a plurality of information acquisition nodes, a coordinator node and a host, wherein the plurality of information acquisition nodes are respectively positioned at corresponding key positions in a production line so as to acquire the production line information at the corresponding key positions and transmit the production line information; the coordinator node is wirelessly connected with the information acquisition nodes and is used for establishing and managing a wireless network, receiving the production line information transmitted by the information acquisition nodes and forwarding the production line information; and the host is connected with the coordinator node and is used for receiving the production line information forwarded by the coordinator node, analyzing the production line information, and broadcasting, printing or displaying an analysis result so as to guide workers to work. The system can collect the production line information timely to guide the workers for material distribution and other work. The wireless connection exists inside the system without wiring, so the deployment and maintenance cost can be reduced, and the information acquisition nodes can move. In addition, the system can be provided with a plurality of routing nodes so as to extend the wireless network transmission distance and increase wireless network node number.

Description

technical field [0001] The invention relates to an Andon system, in particular to a wireless Andon system. Background technique [0002] Andon system (Andon system) is a visual management tool that can collect visual signals of production status and abnormal conditions of the production line, such as machine downtime, quality problems, tooling failures, operator delays, and material shortages. The signal reminds workers to take corresponding measures in time to control production independently. Therefore, through the Andon system, enterprises can achieve visualization of relevant production information, fast information transmission, and closed-loop management control, thereby improving production efficiency and reducing production costs. [0003] With the increasing pressure of competition of enterprises, and the increasing demand of people to improve production efficiency, reduce production cost and reduce downtime, the Andon system is gradually widely used in many indust...
