I believe that many friends have wondered when buying cold chain temperature monitoring devices, what will happen if the iot card installed by cold chain temperature monitoring devices is removed? Can we continue with normal positioning? Today I will answer this question for you.

First of all, we need to understand that the work of cold chain temperature monitoring devices is roughly divided into two aspects: positioning and communication.

The positioning system of cold chain temperature monitoring devices calculates the coordinate position of the GPS device by receiving satellite signals. This signal can be found as long as the environmental conditions are not particularly bad. That is to say, as long as the satellite floating in outer space does not stop working, And you do not turn off the signal reception of the locator, then the cold chain temperature monitoring devices can be positioned from time to time.

So does this mean that cold chain temperature monitoring devices will work even if their iot cards are unplugged? This brings us to the second aspect of cold chain temperature monitoring devices - communication. Generally speaking, the cold chain temperature monitoring devices need to be transmitted to the owner after receiving the signal, which is considered to complete the normal work of the cold chain temperature monitoring devices. If you are only able to locate and communicate, you will not know the location of the vehicle. Therefore, if the iot card in the cold chain temperature monitoring devices is removed, it means that the owner cannot receive the vehicle location information transmitted by the cold chain temperature monitoring devices. It will not be able to carry out remote flameout, remote upgrade, overspeed alarm, trajectory planning and other derivative functions.

Therefore, in order to protect your vehicle and facilitate the use of the multiple functions of cold chain temperature monitoring devices, it is not recommended to unplug the iot card of cold chain temperature monitoring devices. If you are worried about someone unplugging your iot card maliciously, you can also choose to buy cold chain temperature monitoring devices that are card-free.

In fact, the cold chain temperature monitoring devices of the no-plug-in card is to directly install the iot card in the cold chain temperature monitoring devices, which cannot be easily disassembled without professional knowledge and tools. Security is more assured.
