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...

Abstract

The invention discloses a broadband carrier parallel meter reading method and a broadband carrier parallel meter reading system. The broadband carrier parallel meter reading method includes acquiring measurement data on a plurality of remote devices by the aid of concentrators on the basis of power line carrier modes; starting meter reading processes in the concentrators. The remote devices are gauges. The meter reading processes include steps of 1, transmitting N meter reading instructions from the concentrators to all the N gauges in periods T<1> in a unified manner, receiving replies from the gauges in periods T<2> in a unified manner and noting ordinal numbers i as 2; 2, switching to a step 3 if replies from a certain gauge or the multiple gauges are not received by the corresponding concentrator in periods T, or terminating the current meter reading processes if the replies from all the gauges are received by the concentrators; 3, transmitting the meter reading instructions to the gauges without replies again in periods T<i+1>, receiving replies from the gauges in periods T<i+2>, setting the i as i+2, and returning to the step 2. The broadband carrier parallel meter reading method and the broadband carrier parallel meter reading system have the advantage that the meter reading efficiency can be obviously improved by the aid of the broadband carrier parallel meter reading method.

Description

technical field [0001] The invention relates to a broadband carrier parallel meter reading method and system. Background technique [0002] As the construction of the State Grid Corporation's electricity information collection system enters the leading and upgrading stage, the requirements for data volume and data collection frequency are increasing day by day. It is difficult to use the traditional low-voltage power line narrowband carrier for data collection to meet the increasing data collection needs, especially for users. In areas with a large number of stations and a large amount of data required, it is difficult to guarantee the success rate of data collection, and it is difficult to meet the construction goal of "full collection" of the State Grid Corporation of China. [0003] Power line carrier (PowerLineCarrier, PLC) is a unique communication method for power systems. Power line carrier communication uses high-voltage power lines (35kV and above voltage levels), m...
