冷杉的时候st introduced in 2016, Triax Technologies’ Spot-R clip was intended to detect when workers experienced a sudden fall, and pinpointing their location within a jobsite for safety responders. But the little clip has gotten a few new features over the years, and now include integration with access control checkpoints on jobsites.

“Right now we log when people come and go when they come into range of our network,” explains Pete Schermerhorn, CEO of Triax Technologies. The Spot-R technology locates workers via a custom wireless network set up on the jobsite, but it had not been compatible with other RFID-based systems used to track when workers come on and off of the jobsite.

“Now, on a controlled access site, we can show which turnstile workers go through, and combine that combines with geolocation information,” he explains. All of this will be visible on the Spot-R dashboard, and can be set up to work with existing access-control systems.

新的访问控制功能不需要较高的订阅费，除了一些物理升级到旋转门系统外，现有的Triax网络可用于跟踪现场的工人。Schermerhorn说，Spot-R夹在RFID和低能蓝牙方面起作用，除了Triax的专有网络，因此物理升级很小。“We can use this to extend the core functionality of the Spot-R," he says. “We could track the opening and closing of the sites, track worker qualifications. It’s been a pretty loud voice from our customers that they don’t need to have workers wearing multiple RFID tags or clips for different uses.”

Triax Wireless网络没有记录工人的确切位置，只将其缩小到工作地点的预定区域。被动系统没有GP，并且一旦离开工作岗位的网络范围就不会跟踪佩戴者。这极大地延长了长达数月的电池寿命，很多情况下可以延续项目的长度。

An Evolving Technology Finds Broader Use

The Triax Spot-R tags aren’t suited for every site, but the company has targeted it toward vertical construction and similar multistory jobs, where dense sites can be more easily covered by wireless repeaters. That has proven a good fit for Gilbane Construction, which has used the Spot-R tracking devices on over 20 jobsites in the last two years, including the renovation of a 35-story building in New York City.

Gibane高级副总裁兼风险管理总监Don Naber说：“真正吸引我们的产品是它提供的秋季检索服务。”“有一些最初的痛苦，分配和设置剪辑，但我们发现我们有机会改变一些[工人]行为。”

Gilbane’s early deployments of the Spot-R clips resulted in too many false-positive readings of fall incidents, as the contractor found the threshold to trigger the sensor was set too low. But after working with Triax and tweaking the settings for how many feet of sudden movement should trigger an alert, Naber says they began to see changes in the jobsite safety culture. “What we found was that while projects are in the initial stages of work, there’s not much building or foundation, and there are site excavations to avoid. So workers take shortcuts around the site, jumping down a few feet here and there,” he says.

“We saw subs taking routes to different parts of the site, jumping from one elevation to the next.” This lead to the contractor sitting down with the subcontractors and hashing out better, safer routes around the site. “They were saying to us, ‘we have a contractual obligation to you, Gilbane, to reach certain points of the site and we can’t,’” recalls Naber. “It changed how we look at the job and coordinate around the site. We made some adjustments to make it safer. Not to say we weren’t safe before, but the [Spot-R] improved our understanding of issues that weren’t being taken into account before.”

Naber says the clips have not only helped with avoiding catastrophic fall incidents, but in reducing repetitive stress on workers making short hops or drops while traversing a site. “And it’s not just from a repetitive injury standpoint, it’s from a twisted ankle or busted knee standpoint. It’s been a huge positive for us.”

纳伯补充说：“我们正在改变行为。”“人们通过此剪辑更加了解自己的行动和周围环境，并且有一定程度的预防，您只是通过提高意识来获得。”
