The third layer of blockchain is used to ensure safety in wireless data transmission!

Existing issues of wireless data transmission in factories

Currently, in many factories, data transmission between sensors, actuators, etc. and control devices is performed in an exclusive environment and via wired communication, with no external Internet connection allowed for the purpose of maintaining confidentiality.

Here, wired communication is complicated by cables, and the diameter of the cable bundles around the control unit, where the greatest number of connections are concentrated, can be several tens of centimeters in diameter. The more connections there are, the more physical space is taken up by the cables, and the more time is required for fault detection and replacement.

For this reason, there have been attempts to realize wireless communication for some time, but the number of channels for wireless communication has exceeded the allowable range due to data transmission/reception between multiple sensors and actuators and control devices, and it has been determined that a wireless connection is not feasible in reality. Furthermore, the risk of information leakage to the outside is extremely high in wireless data transmission, and together with the problem of the number of channels, this is a major issue.

Solutions that Sees can provide!

We have established a wireless system that enables control within a factory via a single channel, developed a third layer of blockchain as a wireless communication method with enhanced data transmission security, and created an ultra-compact Hashchain chip that is realized using this technology.

In principle, it is a communication system that transmits data only in the transaction portion of the blockchain, and since it is connected to a distributed network, it requires only one channel for wireless communication.
