This online plant noise surveillance system employs wireless technology and explosion-proof sensors, an industry first*1.Even in plants where noise levels change drastically over time, noise mapping can be applied to plan work schedules that will ensure workers do not exceed specified limits for number of work hours in a noisy environment. Through the release of such solutions, Yokogawa is helping to improve health, safety and the environment (HSE) and bolster work productivity.
*1: Based on a June 2019 Yokogawa survey.
Features
The principal components of this system are the WN100 wireless noise meter and the WN30 noise mapping software.
Compliant with the ISA100 Wireless*2 network protocol, WN100 sensors can be installed at many locations throughout a plant to measure noise levels and transmit this data in real time to servers via gateway devices such as the Yokogawa YFGW410 field wireless management station. From this data, the WN30 software can then construct in real time a noise map and superimpose this onto an actual map of the plant. Via an Ethernet connection, computers in the central control room and other key locations can then display these graphics in a web browser.
*2: A network protocol based on the ISA100.11a wireless communication standard for industrial automation that was developed by the International Society of Automation (ISA), and the applications necessary for its implementation. This was approved as the IEC62734 international standard by IEC in October 2014. ISA100 Wireless system is fast and reliable, and can link devices that are scattered over a wide area.
*3. WN100 and YFGW510 (or YFGW520) is installed in plant field.
Both YFGW510 and YFGW520 are available for Field Wireless Access Points for WN100.
(Zoom Image: WN100 Wireless Sound Level Meter )1. Worker health
By viewing noise maps before heading to the worksite, workers can find out in real time what the noise levels will be at that location so that they can take necessary precautions such as bringing earplugs or ear muffs that are designed for the anticipated sound levels, and estimating how long they can stay in that location without experiencing hearing loss.
2. Design of work plans
Occupational safety-related laws and guidelines in each country help to prevent hearing loss by limiting the number of hours personnel can be exposed to specific noise levels. Noise maps can be used to design appropriate work schedules.
3. Reduced wiring costs
This system employs ISA100 Wireless technology. Compared to conventional wired systems, this system is better suited for applications where sensors must be installed over a wide area in often difficult-to-wire locations. Installation costs are lower, even with systems that have many sensors.
