There is no limit to creativity, and the instrument is invented. Today, we introduce a national invention patent for authorization, a gas meter automatic inspection device. The patent was applied by Zhengzhou Enron Measurement and Control Technology Co., Ltd. and was authorized to be announced on April 5, 2017.
Description
The utility model relates to an automatic inspection device for a gas meter complete machine.
Background of the invention
At present, the inspection of the functions and performance indicators of the gas meter complete machine still adopts the method of multi-step execution, manual test and reading detection data, and the test personnel determines whether the product meets the design requirements and production requirements according to the detected data. However, in the inspection process of the gas meter machine, due to the large number of inspection items, it is easy to have problems of artificial fatigue and test results in the inspection process, and the test results vary from person to person, which makes the test results more different. .
Chinese patent document CN204536493U discloses an intelligent gas form board automatic test platform, which comprises a host computer, a serial port module and a plurality of workstations. Each station is provided with a plurality of test equipments and a fixture, and the host computer is connected to the serial port module. The test equipments at each station are connected, and the test equipment at each station is connected with the fixtures at the own station to realize the connection between the test equipment and the circuit board under test clamped on the fixture. Automated detection of various functional parameters of the board under test. However, this platform can only verify the main circuit board of the gas meter. The performance of the gas meter in the state of refueling and power-on can not be tested, which also leads to the assembly of the existing gas meter. After the machine, the gas meter machine still needs to be tested by means of multi-step execution, manual testing and reading of test data, which leads to the problem of time-consuming and labor-intensive inspection process of the gas meter. In addition, in the process of testing the gas meter machine in a multi-step execution, manual test and reading test data, in the process of each step of inspection, the working condition of the gas meter to be tested and the actual work There are differences in working conditions, so the test results obtained from the inspection of the gas meter are greatly different from the performance parameters in the actual working of the gas meter, which makes the test result distorted.

The sound quality of small speakers is also good. It does not have the same large speakers and power as HIFI speakers, and its sound quality cannot compete with large speakers due to physical limitations. But for the vast majority of users who are not golden ears, the use of small speakers with tablets and mobile phones is sufficient to meet their hearing needs.
For Bluetooth retro speakers, I personally think that when many people buy speakers, the appearance is the first priority and the function is second.
We focus on retro Bluetooth speakers,It has high energy density, mini size, light weight and diversified shapes;Excellent fast charging performance, support fast charging and other excellent features
with a brand-new design, showing retro nostalgia without losing fashion. It uses a 2.5-inch speaker and has many functions such as FM radio, Bluetooth fast connection, multi-mode switching, and HIFI high fidelity. Wireless Bluetooth 4-10 hours of playback (at 50% volume), which adds to its unique charm.
Wireless Retro speaker,Waterproof Retro speaker, Portable Vintage speaker,Rechargeable Vintage speaker
