The "OiNET-970" is a system that enables maintenance vehicles to safely pass through level crossings without short-circuiting. When a maintenance vehicle passes through a level crossing, the opening and closing of the barriers are controlled by operating a handheld level crossing control device (onboard unit). The wireless communication between the fixed station of the level crossing control device and the onboard unit uses the 920MHz band specific low-power radio. 【Features】 ■ The fixed station can be installed in the jack panel inside the level crossing equipment box. ■ The onboard unit is handheld, waterproof, and can operate on dry batteries. ■ 920MHz band specific low-power radio specification ARIB STD-T108 does not require a radio license application. ★ We will be exhibiting at the Railway Technology Exhibition 2019. For details, please refer to the basic information section. * For more information, please refer to the PDF materials or feel free to contact us.

We would like to introduce our "Autonomous Environmental Monitoring System." This is an edge-type IoT solution and service that consists of observation stations equipped with LoRa devices to monitor water levels and rainfall in rivers and dams, and relay stations that perform multi-hop relaying of LoRa communication using the LoRaSPN gateway as the base station. It is easy to build a private LoRa system for monitoring water levels and rainfall. Please feel free to contact us if you have any inquiries. 【Features】 ■ Multiple LoRaSPN gateways can be used to construct a Small Private Network ■ LoRa devices can perform multi-hop communication up to a maximum of 6 hops ■ The upper lines of the LoRaSPN gateway can use two types: LTE and Ethernet ■ The interface between the LoRaSPN gateway and the application server adopts SFTP ■ Observation data collected by LoRa devices is saved as CSV files in the LoRaSPN gateway *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce our "IoT Solution for LoRaWAN/LoRaSPN." We offer the LoRaWAN-compliant end device "OiNET-938," which is equipped with analog inputs and contact I/O. The anticipated solutions include infrastructure monitoring and sensing, as well as environmental monitoring in agriculture, forestry, and fisheries. 【Features】 ■ Compliant with LoRaWAN specifications (Class A/C, various MAC commands) ■ Supports a variety of interfaces (standard implementation of analog input, contact input, and contact output) ■ Wide power input range supported (external power: DC +5 to +24V / battery: DC +3V) ■ Supports various sequences (scheduled transmission / periodic transmission / event-driven transmission / status acquisition / control / configuration changes, etc.) ■ Capable of supporting LoRaSPN (Small Private Network) *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce our IP-type product, the 'OST-716BIV model.' This product is a device that transmits contact information using an IP line as the transmission path, and it allows for the expansion of slave devices to increase the number of contacts (DI, DO). Additionally, it supports the SNMP protocol, enabling monitoring and control via an SNMP manager. 【Features】 ■ Transmission of 16 points of contact information through the basic configuration (master device) ■ Expansion of slave devices is possible - By expanding (16 points/device), bidirectional transmission of contact information is possible - Up to 128 points of contact transmission (with a maximum of 112 points in the reverse direction) ■ Monitoring and control possible with up to 4 SNMP managers ■ Various maintenance tasks can be performed via a web browser (including various settings, status display, contact control, log display, etc.) *For more details, please refer to the PDF document or feel free to contact us.
