[New patent introduction] A system for integrated testing of smart gas meter controllers

Today, I will introduce a national invention authorized patent-a system for integrated testing of smart gas meter controllers. The patent was applied for by Hangzhou Pioneer Electronic Technology Co., Ltd. and the authorization was announced on February 23, 2018.

The invention relates to a system for performing integrated testing on an intelligent gas meter controller.

When performing integration tests on smart gas meter controllers, the traditional approach is that testers use various types of verification instruments specified by national and industry standards to artificially test each function specified by the standard, and the smart gas meter control needs to be tested. The rationality of the electrical characteristics/mechanical characteristics/meter data changes of the instrument under different conditions. During these tests, it is necessary to repeat (operate measuring instruments/analog measurement/insertion cards/read-write cards, etc.) actions, which waste time and Manpower, and in the specified time, manual testing efficiency is low, test coverage is not high, and all test data cannot be kept for backup and viewing. If testing is done by extending the time or increasing manpower, the test cost will increase greatly.

In view of the problems in the prior art, the purpose of the present invention is to provide a technical solution for a system for integrated testing of a smart gas meter controller.

The figure is a schematic diagram of the structure of the present invention.

The system for performing integrated testing on a smart gas meter controller is characterized in that the host computer is composed of information input, integration testing, and information output; the information input is input or selection of test case parameters by keyboard or mouse, and According to all the test data returned after the interaction between the various channel devices in the system as the total input information, that is, the test case, it is stored in the database; the integration test is realized by the test content of each function of the smart gas meter controller, and each function The test module is composed of test cases stored in the test modules of different functions in the information input. When the smart gas meter controller is integrated, one or more or all of the test modules are selected for testing; the information output is It is composed of the log generated when the test case is saved by the information input, the test log generated when the integration test is executed, the test report, and the display screen for display and review or the printer for printing and review.

The described system for integrated testing of a smart gas meter controller is characterized in that the main control board is composed of a first microprocessor, a card module, LCD data processing, a value sensor module, a main control board power supply module, It is composed of voltage module, valve module, buzzer signal processing, LED signal processing, button switch, current module and leakage alarm. The main control board is a hardware execution unit for the system to conduct integrated testing of the smart gas meter controller; the first micro-processing The device is used to control the action response and data processing of each component in the main control board, as well as the communication with the upper computer and the smart gas meter controller; the card module is used to write or read the logic encryption IC card or CPU card , Or used to insert the card to the smart gas meter controller; LCD data processing is used to receive the LCD data returned from the LCD module in the smart gas meter controller, and return this data to the information input and information output of the upper computer ; The value sensor module is used to generate the sampling signal related to the measurement, so that the smart gas meter controller recognizes this signal and performs the measurement action, single tube action, magnetic interference action or disconnection action; the main control board power module is 12V/3A The DC adapter provides power to ensure the normal operation of the main control board; the voltage module controls the on and off of the power supply path of the smart gas meter controller through the relay; the valve module is used to control the state of the motor valve or the screw valve valve: open valve Or close the valve, and convert the valve electrical signal into a digital signal, so as to return to the upper computer's information input and information output; the buzzer signal processing is the buzzer generated by the intelligent gas meter controller by the A/D conversion circuit The buzzer electric signal is converted into a buzzer digital signal, so that the digital signal is returned to the information input and information output of the host computer; the LED signal processing is to convert the LED light-emitting electric signal generated by the smart gas meter controller by the A/D conversion circuit LED luminous digital signal, in order to return this digital signal to the information input and information output of the host computer; the button switch controls the button state of the smart gas meter controller through a relay: short press, long press or disconnection; current module through the relay To control the conduction and cutoff of the power consumption test path of the smart gas meter controller; the leakage alarm is used to generate the voltage required for the leakage alarm. According to the type of the leakage alarm, the active leakage voltage value and the passive leakage voltage value can be generated.

The advantages of the present invention: when the system performs information input (test case storage) to the smart gas meter controller, it completely avoids those repeated manual operations, reduces labor intensity, improves test efficiency, and generates more effective tests Use cases; during integration testing, the efficiency and reliability of the entire test task are greatly improved, and the test time (about 80% time saving) and test cost are greatly reduced, especially for those urgent test tasks or series of smart gas The integration test of the meter controller, the integration test of this system guarantees the quality of the product to the greatest extent; the system retains all the test data when the information is input and the integration test, which is convenient for the reproduction of the problem, and can greatly reduce the problem Time for traceability and problem analysis.
