Ronk List of Products and Services

This is a bidirectional proximity warning system that detects the approach of heavy machinery and workers using "ultrasound" and "radio waves." The heavy machinery operator is alerted to danger through "sound" and "light," while the workers are notified through "vibration" and "sound." With one transmission unit, an unlimited number of workers' receivers can be added, and the system can operate with "up to 5 transmission units" at the same site.

• Vehicle Management System

Equipment for the early detection of accidents such as falling trees, slips, falls, heat stroke, self-inflicted accidents due to poor physical condition, and accidents involving heavy machinery. 1. Capable of automatically sending an SOS signal to workers or managers hundreds of meters away in the event of a strong impact, fall, or slip. 2. Detects sounds even in noisy environments like heavy machinery by directly striking the helmet. 3. Usable in mountainous areas where public wireless signals such as mobile radio or Wi-Fi do not reach.

This is a collision prevention alarm system that detects obstacles such as structures using an "ultrasonic sensor" on the upper part (tip) of the aerial work platform. The "ultrasonic sensor" and "control box" installed on the upper part (tip) of the aerial work platform are charged by a solar power system, eliminating concerns about battery depletion and making them "unnecessary to remove." *The control box on the driver's side and the control box on the upper part (tip) of the aerial work platform are wirelessly connected, so there is no worry about disconnection during the crane's movement and extension.

System Overview This is a 2WAY bidirectional approach warning system that can detect two types of approaches: the approach of railway construction vehicles to workers and the approach between railway construction vehicles. The driver of the railway construction vehicle can recognize the approach of workers or other railway construction vehicles by the color of the Patlite light, while workers can sense danger through strong vibrations and sound.

System Overview 1. No wiring required, easy sensor relocation Since the motion sensor and receiver operate wirelessly, there is no need for communication cables or cable installation and maintenance, allowing for easy relocation (reinstallation) of the motion sensor. 2. Installable anywhere With a power supply method using self-generating solar panels and lithium rechargeable batteries, installation is possible even outdoors. 3. N to N Achieves N to N configuration with no limitations on the number of motion sensors installed or the number of receivers managing and monitoring the sensor data.

The 5GHz wireless module developed with RONK's unique technological capabilities has finally arrived! We have developed a 5GHz wireless module to meet the needs of world-standard digital wireless microphones. By using the 5GHz band, we solve issues such as narrow spaces, thin walls, and interference! With uncompressed data transmission, it provides high sound quality and a delay of just 10ms, making the wireless experience seamless. 【Features】 ● Uses the 5GHz band. ● Not affected by Bluetooth or WLAN interference. ● Supports one-to-N configurations. ● Can simultaneously use over 180 microphones. ● Delay is less than 10ms. ● Transmits music signals on two different frequencies (two waves). ● Minimal packet loss due to radio interference (if received data is analyzed and found to be missing due to interference, it is supplemented using data from another frequency). *For more details, please download the catalog or contact us.
