[0002] In the production process of security cameras, testing is an important part of ensuring product quality and functional reliability. Traditional testing methods mainly rely on wired connections, such as connecting the camera to the test computer via USB or Ethernet. Testers will write scripts or manually operate according to different test items to check the camera's video acquisition, transmission, audio communication, infrared / white light illumination, and various sensors and motor functions. However, with the development of wireless communication technology, especially the popularity of 4G networks, security cameras have added the ability to transmit video and data via wireless networks. This capability requires that actual network conditions must be simulated during the test process to ensure that the product can work stably in a real environment.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] A security camera function test system based on 4G network solves the problem that the traditional USB connection method can only test some functions of the security camera, such as video, speaker and microphone, and it is difficult to fully evaluate the actual performance under the 4G network.

[0023] It includes a 4G network security camera 1, a 4G network simulation base station 2 and a test computer 3. The 4G network security camera 1 is connected to the 4G network simulation base station 2 via a 4G network, and the 4G network simulation base station 2 is connected to the test computer 3 via a 4G network. The test computer 3 communicates with the 4G network simulation base station 2 via a router. The test computer 3 is equipped with a test system for performing functional tests on the 4G network security camera 1, and can perform corresponding functional tests on the 4G network security camera 1, including video stream transmission, speaker audio output, microphone audio input, dual filter switching, motor operation, infrared light and white light control, etc.

[0024] The 4G network simulation base station 2 is used to simulate the 4G network base station to realize the signal transfer between the 4G network security camera 1 and the test computer 3. Since it is impossible to completely simulate the function of the 4G network base station, a special function design is carried out based on the test system, including the following:

[0025] The 4G network simulation base station 2 includes a data receiving module, a data sending module, an instruction storage database and an instruction analysis module. The data receiving module and the data sending module are connected to the 4G network security camera 1 and the test computer 3 through a TCP / IP gateway. In addition, the data receiving module and the data sending module define the communication protocol between the test computer 3 and the 4G network security camera 1 to ensure that the test instructions are correctly sent and received, and the test data is accurately returned.

[0026] In actual functional testing, in order to simulate the real working environment of the 4G network security camera 1, sometimes a single function test is performed, and sometimes a combination test of multiple functions is required, such as simultaneous testing of speaker audio output and microphone audio input, etc. At the same time, in the actual control of the 4G network security camera 1, it may be controlled by multiple devices such as mobile phones, computers or other devices. However, since the 4G network simulation base station 2 only provides a transfer function, it is impossible to parse the test instructions of the test system. Therefore, how to enable the 4G network security camera 1 to obtain accurate single instructions or the accurate content of combined instructions is a problem that needs to be solved.

[0027] And the actual 4G network base station can receive many different types of signals, such as computers, mobile phones and sensors, which are distinguished by frequency, time and code. The test instruction of 4G network security camera 1 is only one of them, and the actual test instruction is first encapsulated as a digital signal on the mobile phone or computer, and then converted into an analog signal after decoding and modulation in the 4G network base station, and sent to the 4G network security camera 1. In order to simplify the system, the 4G network analog base station 2 does not have the functions of decoding, modulation, channel access, etc.

[0028] Based on the above problems, an instruction storage database is set up, which stores all the test instructions required for the test of the 4G network security camera 1. The test instructions are analog signals, and each test instruction has a corresponding tag and address. The test system is equipped with an instruction generation module and an instruction sending module. The instruction generation module is used to generate corresponding test instructions according to the input of the tester, such as the above-mentioned video stream transmission, speaker audio output, etc. The instruction sending module can add corresponding tags to the test instructions and send them to the 4G network simulation base station 2.

[0029] After the data receiving module receives the digital test command issued by the test system, the command analysis module retrieves the corresponding test command from the command storage database according to the tag information and sends it to the 4G network security camera 1 to complete the data conversion. After receiving the test command, the 4G network security camera 1 performs the specified test and feeds back the test results to the 4G network simulation base station 2.

[0030] In this way, in actual testing, no matter what kind of test instruction is issued, the 4G network simulation base station 2 does not need to interpret the test instruction. It only needs to read the corresponding tag information to send the corresponding test instruction to the 4G network security camera 1, which greatly simplifies the complexity of the system while being able to complete all functional tests.

[0031] Since the test result output by the 4G network security camera 1 is analog data, in order to perform data analysis, a digital-to-analog conversion component is provided in the test system of the test computer 3, and the digital-to-analog conversion component can convert the analog data into corresponding digital data.

[0032] The test system is also provided with a test data analysis module, and the analyzed test data is sent to the data analysis module. The data analysis module stores standard data of different test items. The corresponding standard data is retrieved according to the test data for comparative analysis to judge the performance and reliability of the 4G network security camera 1.

[0033] In order to test the anti-interference ability of the 4G network security camera 1, the 4G network simulation base station 2 is also provided with an interference signal sending module, which stores interference data, such as instructions of other models of 4G network security cameras 1, instructions of other devices, etc.; a specific time node is set in the interference signal sending module, and different interference data are randomly retrieved and sent to the 4G network security camera 1 at the specific time node. After receiving the test instructions and interference data, the 4G network security camera 1 performs corresponding actions and feeds back the test data. At the same time, after sending the interference signal, the interference signal sending module sends the information of sending the interference signal to the 4G network security camera 1 to the test computer 3, so that the test system can judge the anti-interference ability of the 4G network security camera 1.

[0034] In addition, a command registration module is also provided in the 4G network simulation base station 2. When a new test item is added to the test system, the command registration module stores the corresponding test command in the command storage database after adding the corresponding mark, and sends the mark information to the test system at the same time. Through the above design, a simple and efficient test of the 4G network security camera under 14G communication can be achieved.

[0035] Through the above design, automated testing can be achieved, including instruction sending, function execution, and collection and analysis of test parameters, which improves test efficiency and reduces human errors.

[0036] As a specific implementation method, a security camera function test method based on a 4G network is also included, which specifically includes the following contents:

[0037] Step 1: Configure 4G network security camera 1 to enter test mode;

[0038] Step 2: Start the 4G network simulation base station 2 to provide a 4G network access point for the 4G network security camera 1;

[0039] Step 3: Establish a connection between the 4G network security camera 1 and the TCP / IP gateway through the 4G network;

[0040] Step 4: The test computer 3 runs the test system and sends a digital test command to the 4G network simulation base station 2 through the TCP / IP gateway. The 4G network simulation base station 2 converts the received digital test command into a test command and sends it to the 4G network security camera 1;

[0041] Step 5, the 4G network security camera 1 performs corresponding functional tests according to the received test instructions, including but not limited to video stream transmission, speaker audio output, microphone audio input, IR-CUT switching, motor operation, infrared light and white light control, etc.;

[0042] Step 6: The test system collects and analyzes the test data returned from the 4G network security camera 1 to evaluate its performance and reliability and obtain test results;

[0043] Step 7. Adjust the settings of the 4G network security camera 1 or fix the problems found according to the test results, and then repeat steps 4 to 6 until all test results of the 4G network security camera 1 meet the predetermined standards.

In the absence of conflict, the same embodiment and different embodiments of the present invention can be combined with each other;

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
