At present, there are a variety of brands of cold chain temperature monitoring devices on the market, and the price of the products ranges from dozens to hundreds to thousands of yuan. Each company has its own characteristics about the function of the products. In general, cold chain temperature monitoring devices are mainly divided into vehicle locator and personal locator. GPS vehicle locator is a GPS device installed in the car with GPS receiving function, it can receive the location information in real time sent to the owner's mobile phone or enterprise platform, traffic department monitoring platform, can be very convenient to achieve a variety of functions, such as positioning, monitoring, alarm, lock the car, oil and power off, electronic fence, etc. It is widely used in logistics vehicles, taxis, buses, buses, engineering vehicles, private cars and other fields. There are mainly positioning watches, positioning mobile phones, positioning schoolbags and portable GPS devices on the market; The main features are small and portable. In terms of function, it is a GPS device with GPS receiving function, just like the GPS car locator. Generally comes with a battery, standby time from 1 to 7 days. Mainly targeted at the elderly and children.

GPS monitoring is a technology that combines GPS technology, wireless communication technology (GSM/GPRS/CDMA), image processing technology and GIS technology for remote real-time monitoring of mobile people, pets, cars and equipment. Its application history in our country said long is not long, said short is not short, let us detail below.

gps vehicle monitoring system can effectively improve the informationization level of enterprises, greatly facilitate the collection and transmission of vehicle and cargo information in related industries, realize the information network within enterprises, through the combination of communication technology, computer technology, graphics and image technology, realize the effective tracking of vehicles and cargo, and change static scheduling to real-time dynamic scheduling. Make the transportation process transparent, improve the efficiency of the enterprise and economic benefits.

Like today's buses, dangerous goods transport vehicles, freight logistics vehicles, many local governments have explicitly required to install cold chain temperature monitoring devices; In addition, the leasing industry, credit industry, leasing industry, logistics industry and many small and medium-sized enterprises engaged in such industries have problems in vehicle management, GPS vehicle monitoring and management system can help them solve the problem; At the same time, we can also clearly feel from the market survey feedback, cold chain temperature monitoring devices in the logistics industry, leasing industry, credit industry, and enterprise industry has been widely praised.

In the era of big data, when an ordinary mobile phone sends a positioning instruction SMS to a cold chain temperature monitoring device, the locator can reply a detailed location information SMS to the mobile phone to achieve real-time positioning. The positioning accuracy is also getting higher and higher, and the error range is less than 10m. In addition to mobile phone text messages can be real-time car positioning, you can also use a computer or mobile phone to download the client, no need to send text messages, in the vehicle monitoring platform can clearly see the vehicle location information, alarm times, ignition/shutdown status, etc., vehicle monitoring and management is more convenient. There are four ways to check vehicles, such as the cold chain temperature monitoring devices of mobile communication company: 1, mobile phone download can be attached to the client APP to check vehicles; 2, computer login can be attached to the platform system car inspection; 3, telephone call customer phone inspection. A variety of ways, as customers like to choose to use.

GPS positioning monitoring not only improves the information level of an enterprise, reduces vehicle running time and driver operating time, reduces the transportation cost of the enterprise, and can clearly understand the trajectory of the vehicle through mileage statistics, time statistics, etc., but also can reduce vehicle transportation costs and labor costs. And with the emergence of 3G/4G networks, real-time video monitoring is realized, creating an instant, remote and safe vehicle environment for us.
