Description

Technical Field

[0001] This invention belongs to the field of energy controllers and relates to a testing fixture, testing system and testing method. Background Technology

[0002] The energy controller is installed in public or private transformer areas, enabling flexible access to metering and sensing equipment on both the customer and distribution sides. It features functions such as data acquisition, intelligent fee control, clock synchronization, accurate metering, orderly charging, energy management, circuit status inspection, customer-transformer relationship identification, and power outage reporting. The energy controller adopts a modular design. Different application scenarios have varying requirements for different input / output interfaces, leading to the development of various functional modules. By combining these different types of functional modules, the energy controller redefines the terminal form.

[0003] The functional modules of the energy controller are installed on the main body of the energy controller via a USB bus to expand the main body's functions. These include remote communication modules (such as 4G communication modules, 5G communication modules, etc.), local communication modules (such as power line carrier communication modules, low-power wireless communication modules, RS-485 communication modules, M-Bus communication modules, CAN communication modules, etc.), control modules, remote signaling pulse acquisition modules, and loop status inspection modules. Before application, each functional module of the energy controller needs to be tested. Traditional testing methods involve manual testing of each module individually using the main body of the energy controller or a host computer. The disadvantages are: different functional modules require different testing methods, leading to high costs, heavy workload, and low efficiency for manual operation; and when dealing with multiple functional modules, simultaneous testing requires multitasking, making batch testing difficult. Furthermore, traditional testing methods cannot store the testing process and results of the energy controller's functional modules, resulting in untraceable test results. Summary of the Invention

[0004] The purpose of this invention is to provide a testing fixture, testing system, and testing method to solve the technical problems of high labor costs, difficult manual operation, and low efficiency in the testing of functional modules of traditional energy controllers. It also solves the technical problem of high manual operation difficulty when facing multiple functional modules in traditional testing. Furthermore, it solves the technical problem that the testing process and test results of energy controller functional modules are not traceable in traditional testing.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. It should be understood that the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0043] Figure 1 This is a schematic diagram of the structure of the test fixture provided in an embodiment of the present invention, as shown below. Figure 1 As shown, the test fixture provided by the present invention includes:

[0044] An automatic testing module (not shown) is used to receive test information for automatically testing the functional modules of the energy controller, and to test the functional modules according to the test information in test mode. Specifically, for different functional modules of the energy controller, test information is pre-programmed into the automatic testing module, or a test fixture is connected to a host computer and the manufacturing execution system via a router to obtain the test information from the manufacturing execution system. The test information includes a program for testing all functions of the functional module, the type of the corresponding functional module, etc. Different functional modules correspond to different test information. Because the test fixture in this embodiment can connect to multiple functional modules, the automatic testing module can obtain test information for different functional modules and simultaneously test the functional modules connected to the test fixture.

[0045] An interface module is used to connect to the functional modules of the energy controller. The interface module has at least one USB interface, and each USB interface of the interface module can connect to one functional module. In this embodiment of the invention, the test fixture is connected to the functional modules through the USB interface and interacts with the functional modules for data exchange.

[0046] Terminal blocks are used to connect to the low-voltage terminals of functional modules, enabling automatic testing modules to test the low-voltage terminals of functional modules. Some functional modules require testing of low-voltage terminals. In this embodiment, the test fixture connects to the low-voltage terminals of the functional modules via terminal blocks, interacts with the low-voltage terminal interfaces, converts the signals from the low-voltage terminals, and connects them to the test fixture to assist in testing the functionality of the functional modules. Different functional modules may have different interface types for their low-voltage terminals; therefore, this embodiment is equipped with corresponding terminal blocks, which can be replaced according to actual testing needs.

[0047] A startup module is used to put the test fixture into the test mode to test the functional modules connected to the interface module; wherein, after the startup module is triggered, the test fixture of this embodiment of the invention begins to test the functions of the connected functional modules, such as... Figure 1 As shown, the startup module of the present invention is button-triggered. It should be understood that the startup module of the present invention is not limited to button-triggered. Common device startup methods can be applied to the test fixture of the present invention. For example, the startup module can also be set to switch-triggered or other triggering methods.

[0048] In a preferred embodiment of the present invention, the testing fixture further includes:

[0049] The self-test module (not shown) is used to check the testing functions of the test fixture and report errors when the testing functions are abnormal. The self-test module is a software part that checks the test fixture before the testing function module is tested to ensure the testing capability of the test fixture and greatly avoids abnormalities during testing.

[0050] An indicator module is used to indicate the test status of the functional modules. The test status includes "testing in progress," "test passed," and "test failed." The number of indicator modules is the same as the number of USB interfaces in the interface module. The indicator module can indicate the test status of all functional modules under test. In this embodiment of the invention, for example... Figure 1 As shown, the indicator module is set on the test fixture in the form of an indicator light. It should be clear that the indicator module of the present invention is not limited to an indicator light. For example, the indicator module can also be set to indicate with different sounds, or to indicate with both sound and indicator light.

[0051] In a preferred embodiment of the present invention, the test fixture further includes an Ethernet module for connecting to a host computer. In addition to testing the functional modules by burning in test information, the test fixture of the present invention can also connect to a host computer to transmit test information and communicate with the test fixture through the host computer. It can also obtain the test status in real time and control the test.

[0052] Furthermore, the test fixture of this invention can also be equipped with corresponding hardware modules according to actual applications, such as adding a new module for alarming abnormal interruption of the test when the test mode is started.

[0053] The test fixture of this invention transforms the testing process of functional modules from traditional manual operation to automated operation, saving labor costs and avoiding errors caused by the complexity of the testing process during manual operation. Furthermore, the test fixture of this invention can test batches of functional modules without requiring manual operation of multiple functional modules simultaneously. In addition, the test fixture of this invention can connect to a host computer for real-time communication, solving the problems of uncontrollable testing process and untraceable testing process and results when testing functional modules.

[0054] This invention also provides a testing system for an energy controller functional module. Figure 2 A block diagram of a test system provided in an embodiment of the present invention, such as Figure 2 As shown, the test system includes:

[0055] At least one of the above-mentioned test fixtures, although the test fixtures of the embodiments of the present invention can process the tests of different functional modules in batches, the more functional modules there are, the slower the processing speed of the test fixtures will be. On this basis, for too many functional modules, in order to ensure higher efficiency, multiple test fixtures can be set up for testing.

[0056] The host computer connected to the Ethernet module of the test fixture via a router; and

[0057] A manufacturing execution system connected to the host computer; the manufacturing execution system is used to transmit test information to the test fixture via the host computer to enable automatic testing of the functional modules connected to the test fixture, and to receive the test results of the functional modules connected to the test fixture via the host computer.

[0058] It should be noted that the testing system of the present invention may also consist of only testing fixtures, and the test information may be burned into the testing fixtures.

[0059] In the testing system of this invention, the test fixture is connected to a host computer via a router. The host computer is connected to a manufacturing execution system (MES) and communicates with the test fixture to monitor or control the testing in real time. The host computer also connects to the MES, obtaining information such as the type of functional module and test information from the MES and transmitting it to the test fixture to perform functional module testing. After testing the functional module, the test fixture uploads the test results or test process to the host computer, which then uploads them to the MES. When the MES malfunctions, the host computer can also store the communication information of the test fixture and wait for the MES to return to normal before uploading.

[0060] The testing system of this invention transforms the testing process of functional modules from traditional manual operation to automated operation, saving labor costs and avoiding errors caused by the complexity of the testing process during manual operation. Furthermore, the testing system of this invention can test batches of functional modules without requiring manual operation of multiple functional modules simultaneously. In addition, the testing system of this invention is connected to a host computer and a manufacturing execution system, and through real-time communication with the host computer, it solves the problems of uncontrollable testing process and untraceable testing process and results when testing functional modules.

[0061] This invention also provides a testing method for an energy controller functional module. Figure 3 A flowchart of the testing method provided in the embodiments of the present invention is shown below. Figure 3 As shown, the test methods include:

[0062] Power on the test system, and then the test fixture self-test module will check the test function of the test fixture. If the test fixture has an abnormality, it will report an error and stop the test, waiting for maintenance. When the self-test module detects that there is no abnormality in the test function, the manufacturing execution system transmits the test information of the functional module connected to the interface module to the test fixture through the host computer.

[0063] The test fixture is initialized, that is, each module of the test fixture is restored to its initial state.

[0064] The system detects the startup module of the test fixture until the test fixture enters the test mode, indicating that the functional module to be tested is ready for testing, and then powers on the corresponding functional module.

[0065] The test fixture tests the corresponding functional modules based on the acquired test information. Specifically, the test fixture interacts with the functional modules through interface modules and terminal blocks to test the functional modules.

[0066] When the test status of a functional module is "test passed", the test result is written to the tested functional module, and the test result and test process are uploaded to the host computer. The host computer then uploads the test result to the manufacturing execution system to ensure the traceability of the test process and test results. At this time, the power is cut off to the tested functional module, and the corresponding indicator module of the tested functional module indicates that the test is passed, so as to remind the operator that the corresponding functional module has passed the test.

[0067] When the test status of a functional module is "test failed", the power is cut off to the functional module that failed the test, and the corresponding indicator module of the functional module indicates that the test failed, so as to remind the operator that the functional module has failed the test.

[0068] Finally, a decision will be made based on the actual situation whether to continue testing. If testing continues, wait for the new functional module to be installed on the test fixture before starting testing.

[0069] The testing method of this invention transforms the testing process of functional modules from traditional manual operation to automated operation, saving labor costs and avoiding errors caused by the complexity of the testing process during manual operation. Furthermore, the testing method of this invention can test batches of functional modules without requiring manual operation of multiple functional modules simultaneously. In addition, the testing method of this invention, through a host computer and manufacturing execution system, solves the problems of uncontrollable testing process and untraceable testing process and results when testing functional modules.

[0070] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
