A service management system validates service on building management systems. Devices of the building management systems include wireless transmitters (for example, radiofrequency identification (RFID) tags) for transmitting wireless signals containing identification information. During service, a technician reads the identification information using a mobile computing device (for example, an RFID reader) while also recording the signal strength of the wireless signals. The mobile computing sends the identification information and signal strength information to a connected services system along with information about the service, and a validation module confirms that the identification information and signal strength information indicates that the technician was actually in the vicinity of the devices that were serviced.

Method and apparatus for verifying service of installed devices using RFID

A service management system facilitates and validates service on building management systems. A service workflow module receives device events from control panels of the building management systems and combines them with local service data from mobile computing devices of technicians performing the service, generating service events. The service workflow module receives ambient radiofrequency (RF) signal data detected from the location of serviced devices. A validation module stores the ambient RF signal data and generates and a device fingerprint based on the ambient RF signal data. After device fingerprints based on the ambient RF signal data have been accumulated, the validation module determines whether current service events and ambient RF signal data are coherent with the device fingerprints and previous ambient RF signal data. The service workflow module also infers the location of the technician based on the ambient RF signal data and sends navigation information to the mobile computing device.
