Despite the wide availability of handheld devices and temperature sensors currently on the market, many hypermarket operators still choose Advantech. The main reason is that Advantech’s solutions are unique and innovative technologies.
Mr. Yang pointed out that the most notable feature about Advantech’s PWS-472 industrial-grade handheld terminal is that it supports IR temperature input, which is particularly relevant for cold chain retailers. Additionally, the device is based on Android OS, thus providing an open platform that facilitates system integration,which can significantly improve operational efficiency.
Over a wireless network, the TREK-120 LoRa wireless cold chain sensor can be installed in a matter of seconds once the installation location has been confirmed. This is a sharp contrast against traditional wired sensors that require cabling to be installed, which can be time consuming and difficult to install. Furthermore,the TREK-120 can simultaneously measure food temperature, humidity, and vibration levels.Although the functionality of the TREK-120 is relatively similar to other general sensors in terms of items to be measured, the TREK-120 can perform data transmission over long distances with low power consumption. In fact,it can be used for many years without having to replace the battery.
Mr. Yang explained that traditional sensors use Wi-Fi or Bluetooth for data transmission, the biggest drawback of which is their large power consumption. This requires users to recharge or replace batteries often in order to avoid data loss. Even if a low power consumption Bluetooth technology were to be launched in the future,it would still likely be vulnerable to outside interference, making it unsuitable for cold chain food safety monitoring.
Since LoRa has a higher penetration rate and longer transmission distance than previous transmission methods, it is quite adequate for hypermarkets to install one or two gateways,which reduces system installation costs relative to wired systems. Furthermore, LoRa base stations are relatively easier to install. All that is required for any IT device to be taken as a base station is to install software and a dongle. Thus,stability and reliability in telecommunication services are easily realizable.
Demonstrating Advantech’s commitment to meeting customer needs, the company is dedicated to ensuring smooth system implementation. Because LoRa operates mainly in the global free-to-air frequency band, it can easily overlap communication frequency bands already used by the customer, causing mutual interference between signals. The hypermarket encountered this problem while installing the Advantech Cold Chain Management Solution,and Advantech engineers immediately assisted with adjusting the operating frequency band.Additionally, the system was set up so that the sensors would first inquire as to whether there is any signal occupying the channel before transmitting data, thus ensuring data transmission quality.
With modern society’s emphasis on food safety, a reliable solution for complete cold chain management can help retailers ensure food safety, which can give their customers peace of mind while also protecting their reputation. Since the hypermarket introduced Advantech’s Cold Chain Management Solution, their practices for monitoring frozen/refrigerated food product safety have fallen in line with global trends. With the initiative demonstrated by this hypermarket, more retailers are expected to be motivated to introduce Advantech’s Cold Chain Management Solution.
