Description

Technical Field

[0001] The utility model relates to the technical field of tobacco informatization, and particularly relates to a tobacco equipment status monitoring device with multi-mode wireless data transmission. Background Technique

[0002] In the production process of the tobacco industry, equipment status monitoring is a key link to ensure production safety, improve production efficiency, and reduce maintenance costs. However, there are many deficiencies in traditional tobacco equipment status monitoring technologies, which limit their wide application in modern tobacco production.

[0003] Firstly, in traditional monitoring technologies, piezoelectric accelerometers are often used to detect vibration signals. These sensors output analog signals, which need to be sampled by a complex conditioning circuit before data processing. This process not only increases the complexity and cost of the system, but also makes deployment and maintenance extremely inconvenient. In addition, piezoelectric accelerometers and their supporting equipment are usually large in volume, high in power consumption, and analog signals are easily affected by internal and external interference during transmission, affecting the accuracy and reliability of monitoring data.

[0004] Secondly, traditional status monitoring devices mostly use wired connection methods, which require both wired power supply and wired data transmission. This method is limited in conditions during on-site deployment and must provide a fixed wired connection for monitoring devices, which not only increases the installation difficulty and cost, but also limits the flexibility and scalability of monitoring devices. Especially in the complex and changeable industrial field environment, wired connections are often difficult to adapt to various working conditions and scenarios and cannot achieve large-scale deployment.

[0005] In summary, there is an urgent need in the market for a new, efficient, and low-cost tobacco equipment status monitoring device. This device should be able to overcome the deficiencies of traditional technologies, realize real-time monitoring of equipment status and wireless data transmission, while reducing the system volume, power consumption, and cost, and improving the accuracy and reliability of monitoring data.
