- We received feedback from customers that they want to monitor the opening and closing status of building doors in real-time and at a low cost. In fact, when installing devices to detect opening and closing, significant costs are incurred for wiring and power work to notify the central system of the opening and closing status. - Therefore, we utilized Sigfox as a means to notify the central system from the door opening and closing detection device, and by using rechargeable batteries, we significantly reduced construction costs. - We developed an application that detects changes in the door opening and closing status by leveraging the global IoT network Sigfox, receiving signals from the detection device, and sending them to the cloud, allowing the status to be visualized in a web browser. - There are two main features: 1. You can view a list of changes in the door status (closed to open, open to closed) and any abnormalities in the detection device (such as low battery voltage or no communication for a certain period). 2. The application displays an alert on the screen for doors that are left open as an abnormality and also triggers an alert sound. Building managers no longer need to check each door individually; they can focus on checking the status of detection devices that are abnormal or doors that are left open.

I will introduce "Application Development Using RESTful API with Python." "RESTful API" refers to an API formulated according to the design principles known as REST. While REST itself is a broadly applicable abstract model, the application of REST concepts to Web APIs is referred to as RESTful API. The key point is that the design of REST is highly compatible with web applications. REST APIs have a simple design, but they enable the realization of distributed applications and can communicate using the already widespread web HTTP communication in a lightweight data format called JSON. [Details (Partial)] ■ Developing RESTful API with Python ■ Adding functionality to control systems used in experimental facilities ■ Adding applications that specify control data and visualize it in an easy-to-understand manner, etc. *For more details, please refer to the related links or PDF materials, or feel free to contact us.

We will introduce the implementation of "Linux server replacement/migration." "Server replacement/migration" refers to the process of replacing aging existing servers with new ones or servers that have equivalent functionality. Our company has conducted migration work for servers that are over 10 years old, and the risks of failure due to aging, as well as the difficulty of migrating old systems to new servers, increase with the passage of time. Additionally, if those with knowledge of the servers are no longer present on-site, the project timeline can expand. It is advisable to plan in advance to enable maintenance approximately every five years. [Details] ■ Since most of the documentation from that time is no longer available, we conducted the migration to new servers through phases of investigating and organizing the specifications of the existing servers, followed by design, implementation, and testing. *For more details, please refer to the related links or PDF materials, or feel free to contact us.
