Embodiment Construction

[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0036] A period checking method for running an intelligent heat meter online, the specific steps of the method are:

[0037] (1) The smart heat meter cluster is installed to form a tree topology structure, and the flow data of the total meter and each sub-meter in the smart heat meter cluster can be obtained remotely, and the flow conservation basic model of the smart heat meter cluster can be obtained;

[0038] (2) According to the tree topology formed by the intelligent heat meter cluster, the virtual branch is introduced to dynamically correct the topology model of the intelligent heat meter cluster, and the initial flow conservation algorithm model is obtained;

[0039] (3) Record the flow data o...

Abstract

The invention relates to an intermediate check method for online operating intelligent heat meters. The method comprises specific steps: (1) an intelligent heat meter cluster is arranged to form a tree topology structure, and a flow conservation basic model for the intelligent heat meter cluster is acquired; (2) an initial flow conservation algorithm model is acquired; (3) the flow data of the intelligent heat meter cluster in an initial state are recorded, and initial errors are calculated; (4) during an intermediate check setting time limit, an intermediate flow conservation algorithm modelis acquired; (5) relative errors are calculated during the intermediate check setting time limit; (6) correction and uncertainty evaluation are carried out on the calculation result; and (7) the current intermediate errors and the initial errors are compared for intermediate check evaluation. The method of the invention aims in that all online operating intelligent electric energy meters are subjected to high-efficiency intermediate check at a low cost, the operation error change trends are focused, the use of an external standard instrument is not needed, and thus, a power supply side and a power consumption side can know the accuracy of the electric energy meter metering device in real time.

Description

technical field [0001] The invention belongs to the field of calorie measurement, in particular to a period checking method for an online smart heat meter. Background technique [0002] Heating is needed in northern my country in winter. In order to save energy and reduce smoke and dust, many areas have centralized heating through heating networks and sell heat energy as a commodity. The heat meter is an instrument for calculating heat. The working principle of the heat meter: install a pair of temperature 1 sensors on the upstream and downstream pipes passing through the heat-carrying fluid, and the flow meter is installed on the fluid inlet or return pipe (the flow meter is installed The position is different, the final measurement results are also different), the flowmeter sends out a pulse signal proportional to the flow rate, a pair of temperature sensors give an analog signal indicating the temperature, and the totalizer collects the signals from the flow and temperatu...
