Repair Center Risks and Challenges

As with manufacturing plants, it is difficult to fully introduce telecommuting at repair centers, and employees will inevitably have to work on site. Normally, we work while ensuring social distance, but depending on the work, it is unavoidable to have a close conversation during meetings, education/guidance, consultation, etc. In addition, even if all measures are taken in the workplace, the risk of infection outside the home or workplace cannot be eliminated, and there is a risk of clusters occurring due to viruses brought in from outside.

Once an infected person or a close contact person is confirmed, there is no way to objectively measure who and how much contact was made in the repair center, and it is difficult to narrow down the contact target based on ambiguous information based on memory. I had to. At an overseas repair center, when an infected person was confirmed, the entire line had to be stopped, which had an impact on repair work. Establishing countermeasures to minimize this was an urgent issue.

The tracking solution provided by Macnica networks is LoRaWAN from France's Actility.^®/A system that monitors contact status using a small terminal compatible with Bluetooth Low Energy (hereinafter referred to as BLE). The dedicated terminals worn by each employee use a unique algorithm that utilizes BLE wireless communication to measure the distance and contact time between each other, and if the contact exceeds the standard value for close contact, an "alert" will be sent to LoRaWAN.^®It is sent over the wire to a central management application on the cloud. The contact alert status of all devices is displayed and recorded on the application. Data can be searched by date and time, and CSV file output is also possible.

Olympus decided to introduce it because it was superior in the following points.

• Quickly narrow down contacts based on accurate and objective contact data
• There is no manufacturer that provides similar services on a practical basis in Japan
• Can be installed immediately after purchasing a dedicated terminal and gateway
• The terminal is very small and lightweight, and does not get in the way of work
• Since it uses LPWA communication (LoRaWAN^®) that can cover a wide range, the number of gateways installed and communication costscan be reduced LoRaWAN^®wireless communication quality is stable

運用と効果

This solution is currently in operation at two repair centers and monitors the contact status of hundreds of employees. Employees wear a dedicated terminal on their chest at the start of work, and work while wearing it until the end of work. Since the terminal is small, it does not interfere with work and is operated with less burden.

When an employee is suspected of having been in close contact with an employee, this system can be used to quickly identify the person in close contact with the person in the factory, and confirm the effectiveness of this system. is ready.
