Solution
Together with an American system integrator and a world-leading manufacturer of IoT gateways, azeti developed a comprehensive solution for remote monitoring of beverage refrigerators for the customer. For this purpose, individual gateways were developed based on the project requirements. In addition to a large number of interfaces for connecting sensors, the gateway has a mobile radio modem and GPS for data communication. It also includes a rechargeable battery which continues to supply the refrigerators and thus also the gateway with energy when there is no power supply. The finished gateways were installed together with the following sensors and relays:
- Temperature sensor in cooling area
- Temperature sensor for the compressor
- Ambient temperature sensor
- Door contact sensor Sensor for measuring the power supply
- Sensor for measuring whether illuminated advertising is switched on
- Relay for interrupting the power supply to the refrigerator
Part of the azetis software runs on the IoT Gateway to collect the sensor data and evaluate it directly locally. If, for example, the temperature in the refrigerator is too high because the door has not been closed properly, the azeti software automatically sends out an alarm and informs the relevant employees. The azeti software can also determine whether the refrigerator requires maintenance. This is done by means of various measuring points. Examples are the running time of the device, the heat pattern of the compressor in the refrigerator or deviations in power consumption.
In addition, the beverage manufacturer can determine where the refrigerator is located using the built-in GPS and battery. He can find out whether it is still at the intended point of sale or has been moved to another location and therefore no longer servesthe purpose of selling drinks. In this case, he can send a signal via the azeti platform to permanently interrupt the power supply to the refrigerator and thus its functioning.
In addition to the opportunities for the beverage manufacturer's service teams, marketing and sales also receive valuable information. All data is made available to the respective departments of the beverage manufacturer on individually adapted dashboards on the azeti platform. Depending on the position and responsibility, the data can be made available and further evaluations can be carried out. In this way, the marketing and sales departments can identify, together with the service department, which sales partners they should focus on.
