What is the JLDN National Lightning Observation Network?

What is the JLDN National Lightning Observation Network?

We conduct accurate and reliable lightning observations in real-time, 24 hours a day.

JLDN (Japanese Lightning Detection Network) is a nationwide lightning observation network operated by Franklin Japan. It consists of 31 sensors from Hokkaido to Okinawa, creating an observation network that seamlessly covers all of Japan. The lightning location accuracy of JLDN has an average positional error of less than 300 meters, which is comparable to large-scale lightning observation networks such as NALDN (North America) and EUCLID (Europe). 【Data Utilization Examples】 ■ Social Infrastructure ■ Protection of Human Life ■ Industry ■ Accident Investigation ■ Research Institutions ■ Media *For more details, please refer to the PDF materials or feel free to contact us.

[ZEROSAI Implementation Case] Preemptive Work Feasibility Assessment During Abnormal Weather Conditions

[ZEROSAI Implementation Case] Preemptive Work Feasibility Assessment During Abnormal Weather Conditions

Utilized from weather forecast acquisition to telephone meetings with clients! Case study of erosion control construction.

We will introduce the implementation results of the natural disaster prevention system "ZEROSAI." In Oita Prefecture, for mountain conservation work, we introduced the "ZEROSAI" disaster prevention panel, N sensors, disaster prevention lights, cameras, and power boxes to obtain pinpoint weather forecasts for pre-work feasibility assessments based on rainfall, strong winds, and temperature. As a result of the implementation, the objectives were achieved. Additionally, by utilizing "ZEROSAI," we were able to make pre-work feasibility judgments, conduct pre-evacuations during abnormal weather, manage mortar quality in low temperatures, and hold phone meetings with clients using live cameras. [Case Study] ■ Objectives - Obtain pinpoint weather forecasts - Pre-evacuate during abnormal weather (rainfall, strong winds) - Allow clients to grasp real-time site conditions (cameras) ■ Effects - The above implementation objectives were achieved - Pre-work feasibility judgments - Pre-evacuations during abnormal weather - Mortar quality management in low temperatures - Phone meetings with clients using live cameras *For more details, please refer to the PDF document or feel free to contact us.

[Example of Technical Proposal Utilization] Ministry of Defense Ordered Construction Heavy Rain and Strong Wind Countermeasures

[Example of Technical Proposal Utilization] Ministry of Defense Ordered Construction Heavy Rain and Strong Wind Countermeasures

The natural disaster prevention system ZEROSAI can be utilized not only for on-site safety measures but also for technical proposals.

The natural disaster prevention system ZEROSAI can be utilized not only for safety measures on-site but also for technical proposals. Here are examples of how ZEROSAI's technical proposals have been used in construction projects ordered by the Ministry of Defense. Challenges on-site: Key points of evaluation 1. What considerations should be made when conducting material lifting operations during strong winds? 2. What measures should be taken to prevent material scattering during strong winds? 3. Given the frequent typhoons and sudden heavy rain or strong winds, how can we understand the approach of rain clouds and strong winds and take appropriate measures? *For more details, please visit our website or feel free to contact us.

[ZEROSAI Implementation Case] Process Management at a Site Where Work Cannot Be Done When It Rains

[ZEROSAI Implementation Case] Process Management at a Site Where Work Cannot Be Done When It Rains

Reduction of work loss due to sudden rain in project management! Case study of road improvement construction.

We will introduce the implementation results of the natural disaster prevention system "ZEROSAI." In the road improvement project at the Okinawa General Bureau, many processes cannot be carried out when it rains. Therefore, "ZEROSAI" was introduced for weather forecast-based process management and measures against rising body temperature. An electronic display board was installed in a location visible from anywhere on the large site to show temperature and humidity. Additionally, high-precision precipitation forecasts were used to review the processes three times a day. As a result of the implementation, not only was the weather checked at each process meeting, but emails were also sent when forecasts changed, allowing for a work process focused on efficiency and reducing work losses due to sudden rain. [Case Study] ■ Objectives - Measures against rising body temperature are needed due to the lack of shade or objects to block the hot wind. - Many processes cannot be carried out when it rains, necessitating weather forecast-based process management. ■ Measures - An electronic display board was installed in a location visible from anywhere to show temperature and humidity. - High-precision precipitation forecasts were used to review the processes three times a day. ■ Effects - No one suffered from heat-related illnesses. - Work losses due to sudden rain decreased. *For more details, please refer to the PDF document or feel free to contact us.
