Embodiment 1
[0038] Embodiment 1: a broadband carrier parallel meter reading method, using a concentrator to obtain metering data on a remote device based on a power line carrier to multiple remote devices, the remote device is a meter; start in the concentrator Meter reading process;
[0039] The meter reading process includes the following steps:
[0040] Step 1: Concentrator at T 1 Send N meter reading commands to all N meters uniformly within the time period, and at T 2 Response from the meter is uniformly received within the time period; sequence number i=2;
[0041] Step 2: If the concentrator is at T i If no reply from one or more meters is received within the time period (that is, there are still meters that have not responded), go to step 3; if the concentrator receives replies from all meters, the meter reading ends;
[0042] Step 3: At T i+1 Resend the meter reading command for unresponsive meters within the time period; at T i+2 To receive replies from the meter within th...
