Machine-to-Machine (M2M) applications are found within a wide range of industries, these include automatic meter reading (AMR), vending machines, point of sales (POS) terminals, transport and logistics (fleet management), healthcare, security technology and many other applications.
M2M Embedded Systems are used to integrate technologies such as Wi-Fi, GPS, Bluetooth, Java and Zigbee to terminals that are connected to applications. (Find our more on M2M Embedded Systems...)
How does it work?
Automatic Meter Reading
Automatic Meter Reading (AMR) automatically collects consumption, diagnostic and status data from water meter or energy metering devices (water, gas, electric) and transfers the data to a central database for maintenance issues, billing, troubleshooting and analysis. This saves time for Engineers to take periodic trips to each physical location to read a meter. The billing can also be based on real time consumption rather than on estimates.
AMR technologies can be handheld, mobile or network technologies based on telephony platforms (wired and wireless), radio frequency (RF) or power line transmission. The devices can connect to a central host via a wireless network from any location and transmit data from one another.
Vending Machine Monitoring
Vending machine monitoring can automatically collect stock levels, sales transactions, vending temperature, ingredient levels and send alarms on events of crime and stock shortages. The data and information is transmitted to a central host and read on an internet based system or sent directly to a computer located in the headquarters.
The communication to the vending machine is made over wireless networks. The technology connected is usually a cellular GSM/GPRS modem or GSM/GPRS router connecting via an RS-232 interface providing connectivity to wireless networks.
