Industrial wireless networks are rapidly expanding to factories and assembly plants around the world. Wireless technology is also very cost-effective, stable and flexible, easy to install and maintain, and does not require installation and maintenance of cables and troubleshooting of cables, so wireless technology also offers high ROI. And it is based on the many advantages described above that wireless networks are becoming more and more popular as an efficient way to connect switches, sensors and various types of controllers to machines. Our Honeywell Sensing and Control Division was surprised to find that our customers are seeking wireless solutions for all new and special applications. We had expected wireless technology to be used in manufacturing and assembly, but for now we find that this technology is being extended to a wide range of other applications and sectors. One very promising application of wireless technology is large outdoor warehousing, shipping and aerospace facilities where underground cabling is expensive because the continuous rolling of heavy vehicles can damage underground cables and connectors. Groundwater also corrodes cables in many areas. In many areas of extreme climate change, annual surface freeze-thaw can also damage the cable. Once the cable is damaged, troubleshooting, detecting and repairing the damaged cable will be very difficult and costly, especially in areas with heavy traffic. Can you imagine the cost of shutting down a runway in a busy airport in search of a damaged cable or broken connection? Or in a busy outdoor warehouse or gas station blocked lane? If the problem is good or bad how to do? In contrast, wireless technology offers a simple, cost-effective solution that eliminates the need for trenching and laying underground cables. For example, some large truck gas stations have had such an experience. Some customers turn on the diesel pump and refuel their truck without the gas station operator knowing it. In response to this theft, gas station operators installed a wireless switch on the pump, which alerted the operator with a wireless signal when the pump was on. Caption: In large truck parking lots, wireless switches can be used to prevent theft of fuel. Some truck drivers will forcibly open the pump and unlock the control to steal fuel. With Honeywell's Limitless? Wireless solution, operators can install a wireless switch on the pump's mouth that alerts the office when the pump's mouth is opened. Installing and Maintaining Cable Connections from the Oil Pump to the Gas Station Office will be very expensive, especially as heavy trucks continue to crush underground cables. Not only are wireless technologies less expensive, but the wireless platforms and receivers of such network systems can be built and put to use within hours. The airport also has related applications. In order to solve the problem of heavy cables rolling over the airport runways and boarding lanes, a wireless technology was also used on the hangar gate to indicate the opening or closing of the hangar gates. In addition, many hangars are also open on the hangar gate so that they can enter the hangar without opening the hangar door. In addition to safety considerations, entering the hangar from a hangar wagon also lowers air conditioning and heating costs for airport operators.
