Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope defined in the present application.
As shown in fig. 1-2, the present invention provides a synchronous detection device for electromechanical error of a smart meter.
The device integrates an air blower 1, an air duct, a connecting firmware 4 and a duty ratio tester 5 on a detection table, wherein the air blower 1 is connected with a transformer 6 and a power supply air switch 7, the air duct is connected with the air blower 1, and the connecting firmware 4 is connected with an air duct. The intelligent meter is installed on connecting firmware 4, and through connecting firmware 4 and vent pipe intercommunication, the pulse line of intelligent meter is connected to duty ratio tester 5. In this embodiment, air-blower, vent pipe, connection firmware 4, smart meter all integrate in examining test table below, and duty ratio tester 5 is located and examines test table top and be connected firmware 4 and correspond the setting, conveniently reads data. The connecting firmware 4 is provided with a plurality of, can be used to install finished product table 9 and base table 8, and corresponding duty ratio tester 5 also is a plurality of, is provided with a control valve 3 on every connecting firmware 4 and is used for the break-make of control circuit. A pressure stabilizing source 2 is provided on the vent line for stabilizing line pressure.
On one hand, the detection device provided by the embodiment can determine the distribution of the electromechanical conversion error of the meter and the performance of the magnetic steel. Specifically, after the meter is placed in the connection firmware 4, the meter pulse line is connected to the duty ratio tester 5. During the test, the power supply of the blower 1 is switched on, the wind after the pressure stabilization of the pipeline is acted on the watch through the pressure stabilization source 2, the watch mechanical part moves characters, and meanwhile, the watch pulse starts to be output. In order to ensure the data accuracy, firstly the duty ratio tester 5 discards the first duty ratio data, starting from the second duty ratio data, the duty ratio tester 5 sequentially displays the percentage of the on-time and the off-time of pulse reception, and the distribution condition of the electromechanical conversion error of the meter is judged through the data displayed on the duty ratio tester 5, so that the problems of disproportionate on-off and meter unmeasuring are prevented; or after the magnetic steel slightly fluctuates, the mechanical value changes, and the electronic part does not change.
Because the duty ratio test is added in the test process, the requirement of electromechanical conversion errors is guaranteed, the performance of the magnetic steel is tested, the magnetic steel and the pulse matching degree can be accurately divided by picking the duty ratio with weak magnetic property of the magnetic steel, and therefore the problem that the product flows to the final process is avoided, and the maintenance difficulty is increased.
On the other hand, the detection device provided by this embodiment can detect the smart meter by using a method of presetting electronic values in advance. Specifically, when a finished product table is tested, the finished product table is connected to the connecting firmware 4 in a one-to-one correspondence mode, the initial value of each table is recorded, then the setting card is inserted into the table to be tested, and a fixed number of the tables appears, namely the number of ventilation air flows of the test. When the power supply of the blower 1 is switched on, the watch mechanical part runs to generate pulses, the watch electronic part receives corresponding running after the pulses, when the running of the watch electronic part reaches the early set number, the watch valve is closed, whether the numerical value of the mechanical part is consistent with the numerical value of the set electronic part is read, if so, the mechanical part is qualified, and if not, the mechanical part is unqualified.
By means of the mode of presetting electronic numerical values, manual operation of changing the process is not needed, data calculation is not needed, a plurality of processes can be operated correspondingly by one person, qualification can be judged as long as the data are within the range, manpower resources are effectively saved, the working efficiency is improved, and the production process is simplified.
