Frankly speaking, school bus security is a major concern to all school employees and parents. News accounts appear almost weekly with a story of a child left alone on a school bus for hours. Besides that, drunk driving is often a threat to school bus security. In order to eliminate these dangers, the Swedish system integrator Trinorth came to Ursalink for an advanced IoT solution.

School Bus Security Solution

All the strategic insights boil down to the same basic principles – ensure children’s safety. We’ve done everything to deploy connected devices with high stability to improve the real-time monitoring and on-site visibility.

Our customers were in the search of a reliable and seamless cellular communication and they finally settled on Ursalink industrial cellular router for its top-ranking performance and high scalability.

The solution integrates passenger counter, alcolock, and Ursalink industrial cellular router.

The connection between the passenger counter and Ursalink industrial cellular router relies on the Ethernet service of RJ45. The DI is used for connecting with alcolock, triggering the SMS/Email alarm, and DO is in the control of engine heater through SMS.

The driver needs to check his breath with the alcolock every time before he starts the bus engine. If the test result is negative, the bus will function properly. But if he failed, the system will lock the vehicle automatically, together with an alarm e-mail/SMS sending out to the remote server over 3G/4G network.

Second, with the engine heater, the driver can preheat the bus engine by sending an SMS and makes it start quickly regardless of the cold weather. Speaking of the cold weather, in January the average temperature is 16°C in the far north of Sweden, while at the same time it can be 0°C in the south. (see>>>). And speaking of passenger counter, it is the most critical components of this solution, it helps school to check-in and checkout the number of children, prevent from stranding a child on the bus, and through Python programming, Ursalink router will receive all data from passenger counter, which greatly improved the efficiency.

With the solution adopted, our customers can make the most of their businesses and open up a new era of competitiveness, growth and put the children’s safety at the forefront with a real return on investment.
