How to design and implement wireless alerts from signal lights on factory production lines or the transmission of sensor signals?
Thread Content
Our factory mainly produces food products. Due to the specific requirements regarding various ingredients and their concentrations, signal lights for alarms work well enough. However, it is complicated to transmit the signals from the spherical tank sensors to the control room. Moreover, as we all know, the environment on the production line is quite complex; the cables installed in the factory are inconvenient and often interfere with production processes. Therefore, the factory is considering switching to a wireless system. I’m not sure how this transformation can be carried out
Wireless sensors (temperature, pressure, flow, level), wireless adapters, wireless infrastructure, etc. These can meet your requirements. For specific plans, you can consult manufacturers such as Emerson and Yokogawa
Regarding the control system, special attention must be paid to the reliability of wireless devices in harsh weather conditions such as thunderstorms; this is something that cannot be taken lightly at all. Simple monitoring tasks that use wireless communication to collect data are quite good. However, debugging communication equipment requires a high level of technical skill from the person involved. . . If you lack the necessary skills, it’s advisable not to engage in communication. .
Stability is also the biggest concern for us. The choice of wireless solution was also a last resort; the factory wouldn’t allow the use of wired connections, as that would require digging trenches for wiring, which would take too long. Now we’re looking for a suitable alternative to assess the situation
There are companies specialized in the industrial Internet of Things, as well as related products, such as those that use ZIGBEE wireless networks
Current limited technologies are no longer confined to cable transmission; optical transmission can also be used. After all, wireless methods are not fast enough, and they require a lot of maintenance later on. A lightning protection system is also necessary. A PLC is placed in the workshop to collect all signals, which are then converted from electrical signals to optical signals and transmitted via fiber optics to the desired location, where they are converted back from optical signals to electrical signals. Is laying fiber optics that difficult either?
No matter how far away it is, wireless sensors can be used; the stability is decent, but the signal refresh rate needs to be taken into consideration
