IoT technology has dramatically changed our life in the past decade, and made our life smarter and better. Today, we’re going to share with you a success case-how IoT technology empowers the Mobile VMS(Variable Message Sign).

First of all, we need to know what is Mobile VMS and what is it used for?

Mobile Variable Message Sign

With a single sign that serves multiple functions, Mobile Variable Message Signs (VMS) are an ideal road signage solution for informing, advising and influencing road users and the wider public, applications as below.

Temporary roadworks
Events and crowd control
Advertising
Weather and air quality information

Why Need Mobile Variable Message Sign?

The need for a visible message is not always fixed or permanent, sometimes people need to be informed of temporary roadworks, flood warning, changes in traffic flow or upcoming events in the area, and more recently we have seen mobile displays used to communicate Covid-19 messages.

IoT Technology Empowers Mobile VMS

As we know, the mobile VMS is not always installed in a fixed location, they may be moved to different places wherever it is needed. Besides, the message always changes for different applications, and this has brought some challenges to the owners of mobile VMS, such as

How to manage the massive message and transfer the instant message without going to field?
How to monitor the changing status and location of mobile VMS?

Thanks to IoT technology, the challenges mentioned above have been easily solved by using industrial 5g/4g IoT router and cloud IoT platform.

The industrial 5g/4g router provides robust wireless communication between the field variable message sign and remote cloud IoT platform, and receive instant message or commands from IoT platform. Besides, it is also used to transfer the status of operation of sign and solar panel, as well as battery installed on the trailer.
