Embodiment Construction
[0016] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0017] figure 1 It shows an embodiment of a method of the present invention for checking whether the terminal pulse constant change event recording function is normal: a method for checking whether the terminal pulse constant change event recording function is normal, comprising the following steps:
[0018] 1. Develop an analog table with at least two sets of pulse constants;
[0019] 2. Set a group of pulse constants on the analog meter for the first time on the metering terminal, and make the first record of pulse constant change events;
[0020] 3. The metering terminal performs the first rea...

The invention relates to a method for on-site verification of a distribution transformation monitoring measurement terminal, in particular to a method for detecting whether the terminal pulse constant change event recording function is normal or not. The method comprises the following steps of simulation table making, primary pulse constant setting, primary simulation table data copying and reading, secondary pulse constant setting and secondary simulation table data copying and reading. Data of a simulation table are set in an oriented mode twice, the data of the simulation table are read through the detected terminal, an abnormal time record is formed, the data obtained twice after parameters are issued by the terminal are read and compared, whether the terminal pulse constant change event recording function is normal or not is comprehensively judged, and whether the fault terminal can automatically store an abnormal event or not can be effectively judged according to the method.
Description
technical field [0001] The invention relates to a method for on-site verification of a distribution transformer monitoring and metering terminal, in particular to a method for checking whether the terminal pulse constant change event recording function is normal. Background technique [0002] The distribution transformer monitoring and metering terminal has been verified in the laboratory before the on-site installation, but after the metering terminal has been used for a period of time on site, some problems will occur. method or device. [0003] In the operation failure of the metering terminal, the most common problems are the confusion of historical data records and poor communication with the uplink channel. If the historical data records are chaotic, it is impossible to accurately monitor the abnormal time, resulting in the inability to accurately and timely Find out when and where the metering terminal failure occurred. Contents of the invention [0004] The purpo...
