5.3 Meter Operation in Systems
5.3.1 Remote Meter Reading in Energy Production Applications
The ZxQ is most suitably employed in production and transmission
networks and by large industrial consumers. Such networks and consumers
seldom read their meters manually on-site but employ automatic remote
meter reading .
Remote meter reading requires communication between the meter and the
central station . This is achieved using a communication unit via a serial
interface or modem. Normally the central station is scheduled to call each
meter in the system and to acquire the required data. The following
functions can be performed:
• Meter reading; acquisition of meter reading and status information of
the meter
• Time synchronisation; with the central station time
Communication with the meter can be established using the standard dlms
protocol according to IEC62056 series.
5.3.2 Types of Communication
Communication between the central station and the meter can be
performed using any of the following types of communication:
• Dedicated (leased) lines
• Permanently installed connections, bus systems, etc.
• Public telephone network using PSTN modems
• Public mobile telephone network using GSM modems
• Radio transmitters and receivers
• Others such as ISDN, TCP/IP, Blue Tooth, PLC, etc.
