Description

Technical Field

[0001] The present invention relates to the technical field of security system testing, and in particular to a security system testing method and device, and a computer-readable storage medium. Background Art

[0002] In large-scale security systems, due to the multiple deployment locations, brand procurement differences, and asynchronous hardware model upgrades, the video surveillance equipment and sensor equipment in the security system are characterized by a large number of types, such as Figure 1 As shown, Figure 1 It is a schematic diagram of the deployment of security systems in the prior art.

[0003] This type of security system testing usually has the following problems: First, when testing the alarm handling process scenario, due to site safety and the wide variety of alarm types, it is impossible to support testing by actually generating fire, smoke, etc., and the data formats of different brands and alarm types are inconsistent, all of which need to be covered by the test; second, when testing multi-channel video scenarios of video surveillance, it is impossible to purchase and deploy a large number of real camera equipment of multiple brands and models; third, when an alarm is generated at a certain location, the corresponding video needs to be viewed in real time. The test of this part of the related scenarios requires manual preparation of alarm signals and video stream data respectively. The test data preparation is not simulated enough and affects the test efficiency.

[0004] In addition, in order to reduce the dependence on real hardware devices and reduce testing costs, actual hardware signals can be simulated through video streams and signal streams, so as to provide a solution for efficient and comprehensive testing without actually deploying a large number of hardware devices during the testing process of the security system; however, the existing video stream and signal stream simulation has the following main disadvantages: First, for single device simulation, the access versatility of video streams and signal streams of multiple brands and models is low, and repeated adaptation is required, which is costly; second, the existing method writes parameter logic into the code, resulting in low scalability and diversity; third, the existing simulation data format is relatively simple, and after multiple data formats are accessed, the data needs to be processed according to the diversity when docking with other related modules, and there is a lack of a unified format; fourth, the diversity of video parameters and the linkage of alarm signals cannot be automatically realized, and need to be simulated manually one by one, which is inefficient.

[0005] With regard to the above-mentioned related technologies, when testing the security system, due to the inability to deploy a large number of camera devices for data collection and the wide variety of test scenarios, effective simulation cannot be performed, which affects the test efficiency and accuracy.

[0052] Figure 3 is a flow chart of a method for testing a security system according to an embodiment of the present invention. Figure 3 As shown, the method comprises the following steps:

[0053] Step S302, controlling the alarm signal simulation device to parse the received test data to obtain the test keywords and the preset video type corresponding to the test data, wherein the test data is data describing the preset alarm scene, and the security system is used to monitor the target monitoring area and warn of danger.

[0054] In this embodiment, the collaborative cooperation of three modules, namely, an alarm sensor signal simulation device (i.e., an alarm signal simulation device), a camera video stream simulation device (i.e., a video simulation device), and a sensor signal and video simulation linkage simulation device (i.e., a signal and video fusion module), is mainly utilized to realize the function and performance test of the security system; firstly, the test data can be input into the alarm signal simulation device to parse it and obtain test keywords for subsequent simulation of the sensor signal stream, and the video type of the preset alarm scene corresponding to the test data (i.e., the preset video type) can also be obtained to facilitate the subsequent verification of the function and performance of the security system.

[0055] Combine the following Figure 4 The above embodiments of the present invention are described in detail. Figure 4 is a flow chart of an optional security system testing method according to an embodiment of the present invention.

[0056] According to the above embodiment of the present invention, in the above step S302, the alarm signal simulation device is controlled to parse the received test data to obtain the test keywords and the preset video type corresponding to the test data, including: controlling the alarm signal simulation device to parse the received test data to obtain multiple test keywords and test tags carried by the test data, wherein the test keywords include: sensor keywords and alarm signal keywords; determining that the video type recorded in the test tag is a preset video type.

[0057] like Figure 4 As shown, some keyword fields can be pre-set so that the subsequent alarm signal simulation device can directly parse according to the field name after receiving the test data, so as to extract the keywords therein; in order to simulate the alarm scene more realistically, the keywords here can generally be divided into two types: one is keywords related to sensor equipment, such as brand, model, etc., and the other is keywords related to the alarm scene, such as alarm location, alarm channel, alarm type, alarm level, alarm time, etc.; in addition, when parsing the test data, the preset video type can also be determined according to the video type recorded in the tag (test tag) carried by the test data, so as to provide a reference for the subsequent function and performance testing of the security system.

[0058] Step S304, controlling the alarm signal simulation device to generate an alarm signal stream according to the test keyword.

[0059] In this embodiment, the alarm signal simulation device can be controlled to generate a corresponding alarm signal stream according to the parsed test keywords, that is, to convert the format of the original test data into an alarm signal stream in the JSON message body format, so as to facilitate subsequent testing of the security system.

[0060] According to the above embodiment of the present invention, in the above step S304, the alarm signal simulation device is controlled to generate an alarm signal stream according to the test keyword, including: determining the data format type of the target sensor according to the sensor keyword in the test keyword; determining the keyword-coding format mapping table matching the data format type as the target mapping table, wherein the keyword-coding format mapping table is used to record the mapping relationship between the test keyword and the signal stream encoding; the alarm signal simulation device is controlled to generate an original alarm signal stream according to the test keyword and the target mapping table; performing a format conversion operation on the original alarm signal stream to obtain an alarm signal stream, wherein the format conversion operation is used to convert the signal stream format of the original alarm signal stream into a preset signal stream format, so that the formats of the alarm signal streams received by the video simulation device are the same.

[0061] Combine the following Figure 5 The above embodiments of the present invention are described in detail. Figure 5 is a schematic diagram of a sensor signal flow according to an embodiment of the present invention.

[0062] Specifically, most current simulation methods bypass the original sensor signal stream and directly simulate the JSON message body, without simulating the data format of the real sensor and how to standardize the original sensor data format into the JSON message body. Here, the signal stream format and format encoding content of different brands and models can be pre-configured. For example, the location uses the administrative code, and the alarm signal simulation device selects a signal stream format configuration through the previously set keyword field, and converts the parameter simulation that the user needs to simulate into the original sensor signal stream, such as Figure 4 As shown, the specific simulation process is as follows; 1) Generate the original alarm signal stream: Assume that the test data input by the staff is: the alarm sensor of brand A model a generated a first-level smoke alarm in the lobby of office building B at 2025-01-02 02:47:17; the sensor signal stream format of brand A model a in the configuration file (equivalent to the target mapping table) is composed of 28 bits. The original signal stream of the sensor is configured according to the data stream format to generate Figure 5 The original alarm signal stream shown; 2) Standardization of multiple formats of the original signal stream: Since the original alarm signal stream simulated in the test data will be different due to different format lengths corresponding to different brands and models, or different enumeration mapping relationships, but a unified format is required when interacting with the downstream, the signal streams of different formats can be standardized and mapped according to the rule configuration. The processed format is as follows: {"Alarm location": "Office building", "Alarm channel": "Stairway", "Alarm type": "Door always open", "Alarm level": "Level 1", "Alarm time": "2025-01-02 02:47:17", "Signal identification": 0-non-analog signal, 1-analog signal}; After format unification, the alarm signal stream corresponding to the test data can be obtained.

[0063] Step S306, using the signal and video fusion module to transmit the alarm signal stream generated by the alarm signal simulation device to the video simulation device, so as to control the video simulation device to retrieve the real video stream that matches the alarm signal stream according to the alarm signal stream, wherein the real video stream is the video captured by the image acquisition device that has a communication connection relationship with the video simulation device.

[0064] In this embodiment, after the alarm signal simulation device generates an alarm signal stream, the alarm signal stream can be transmitted to the video simulation device through the signal and video fusion module to control the video simulation device to retrieve a sample video stream (i.e., a real video stream) that matches the alarm signal stream according to the alarm signal stream; since a large number of identical camera devices cannot be deployed for data collection during the actual test process, a small number (one or several) of sample video streams can be retrieved here to provide a data basis and reference for the subsequent configuration to generate multiple configuration video streams, thereby avoiding large differences between the generated configuration video stream and the video required to be linked with the alarm signal stream.

[0065] According to the above embodiment of the present invention, in the above step S306, the alarm signal stream generated by the alarm signal simulation device is transmitted to the video simulation device by using the signal and video fusion module, including: determining the parameter in the alarm signal stream whose video correlation is higher than the correlation threshold as the target parameter, wherein the video correlation refers to the degree of influence of the parameter on the retrieval of the real video stream; controlling the alarm signal simulation device to store the target parameter in the message cache queue, and then transmitting the message cache queue to the signal and video fusion module; and controlling the signal and video fusion module to transmit the message cache queue to the video simulation device.

[0066] Specifically, the alarm signal simulation device usually pushes parameters such as IP, port, video channel, etc. related to the video stream to the MQ message queue (i.e., message cache queue), and then transmits the MQ message queue to the video simulation device through the signal and video fusion module, without the need to transmit the completed alarm signal stream.

[0067] According to the above embodiment of the present invention, in the above step S306, the video simulation device is controlled to retrieve the real video stream matching the alarm signal stream according to the alarm signal stream, including: when the video simulation device receives the message cache queue, the message cache queue is parsed to obtain video stream parameters, wherein the message cache queue is a message queue transmitted by the signal and video fusion module and contains the configured video stream; according to the video stream parameters, the real video stream is pulled from the image acquisition device, wherein the configuration parameters of the real video stream correspond to the video stream parameters.

[0068] Combine the following Figure 6 The above embodiments of the present invention are described in detail. Figure 6is a schematic diagram of parsing an MQ message body according to an embodiment of the present invention. After receiving the MQ message body, the video simulation device can Figure 6 The process shown is to parse and process it step by step, based on the parameters such as the IP, port, video channel, etc. of each sample video stream (i.e., video stream parameters).

[0069] In a specific embodiment of the present invention, a real video stream is pulled from an image acquisition device according to video stream parameters, including: controlling a video simulation device to send a communication connection request to the image acquisition device to establish a communication channel for data transmission with the image acquisition device based on the communication connection request; sending a video pull request and video stream parameters to the image acquisition device based on the communication channel; and receiving the real video stream pulled by the image acquisition device according to the video stream parameters based on the communication channel when a request is received to pull based on the video pull request from the image acquisition device.

[0070] Specifically, the video simulation device can obtain the video stream parameters by parsing the MQ message queue, and use a suitable SDK or tool (such as FFmpeg) to pull sample video streams from real video surveillance devices (i.e., image acquisition devices). This is to obtain video data with real visual effects and features, and can also serve as the basis for subsequent video stream replication and parameter modification.

[0071] Step S308, controlling the video simulation device to generate multiple configured video streams based on the real video stream, wherein the configured video stream is a video obtained by configuring the real video stream using a preset algorithm.

[0072] In this embodiment, in order to enrich the number of video streams to improve the accuracy of the test, the sample video streams can be copied and configured using a corresponding algorithm through a video simulation device to generate multiple configured video streams; both the real video stream and the configured video stream can be used as alarm video streams to test the security system.

[0073] According to the above embodiment of the present invention, in the above step S308, the video simulation device is controlled to generate a multi-channel configured video stream based on the real video stream, including: performing multiple copy operations on the real video stream to obtain multiple sample real video streams; obtaining multiple video configuration parameters of the real video stream, wherein the video configuration parameter refers to a parameter whose degree of influence on the video picture quality is higher than a preset threshold; using a weighted random algorithm to weight the multiple video configuration parameters to obtain multiple weight allocation results; and changing the parameters of any one of the sample real video streams in turn according to each weight allocation result to generate a multi-channel configured video stream.

[0074] Combine the following Figure 7 The above embodiments of the present invention are described in detail. Figure 74 is a schematic diagram of video configuration parameter weight allocation according to an embodiment of the present invention.

[0075] Specifically, video configuration parameters can be dynamically generated based on sample video streams. There are two main configuration processes: one is to obtain the access authentication configuration of the device based on the real sample stream; the other is to use a weighted random algorithm to generate a combination of different video parameters and different configurations for processing video parameters during multi-channel simulation, such as Figure 7 As shown, the weights of various video configuration parameters can be randomly generated first, as shown in Table 1 below, and then any parameter weights are selected for summation (assuming that the resolution weight and S = 100%), and then a random number R between (0, S] is randomly generated, and then the weight interval of R and the parameter value is traversed and compared to determine its configuration. After the dynamic loop processing is completed, the multi-channel video parameter configuration can be as follows: video channel 1 configuration (resolution = 720p, bit stream = main bit stream, saturation = 56, contrast = 78), video channel 2 configuration (resolution = 1080p, bit stream = sub-bit stream, saturation = 40, contrast = 82), video channel n configuration (resolution = 4k, bit stream = main bit stream, saturation = 77, contrast = 83).

[0076] For example, assuming that the resolution parameter values ​​are as follows: VGA weight interval (0,14], 720p weight interval (14,60], 1080p weight interval (60,88], 4k weight interval (88,100], if a random number R=26 between (0,S], then the resolution of the configured video stream can be determined to be 720p based on the fact that 26 belongs to the weight interval (14,60].

[0078]

[0079] When obtaining the access authentication configuration of the device based on the real sample stream, the video surveillance device usually has an access control mechanism to ensure that only authorized users or systems can access the video stream. The authentication configuration usually includes user name, password, access token, signature key, etc., which are used to establish a secure communication channel between the device and the requester; in the simulation test, in order to truly simulate the video stream pulling process, the simulation device needs to obtain these authentication information, which can usually be achieved in the following ways: 1) Configuration file reading: The system administrator or tester stores the authentication information of various devices in the configuration file in advance, such as user name and password. When it is necessary to simulate the video stream of a certain device, the simulation device reads the corresponding authentication information from the configuration file; 2) Dynamic authentication: In some cases, the authentication information may need to be dynamically generated each time the access is made. For example, when using the authentication protocol, a temporary access token needs to be generated. The simulation device needs to be able to dynamically generate the correct authentication parameters according to the actual authentication mechanism.

[0080] Step S310, input the alarm signal stream and the alarm video stream into the security system to perform a simulation test on the preset alarm scene to obtain a test result, wherein the alarm video stream includes: a real video stream and a configuration video stream.

[0081] In this embodiment, if Figure 4 As shown, the alarm signal stream and the alarm video stream can be input into the system under test (ie, the security system to be tested) so as to use the security system to perform a simulation test on the preset alarm scenario and obtain the test results.

[0082] Specifically, the test can be conducted from the following three perspectives: 1) After the alarm signal stream is input into the system under test, verify whether the system under test can quickly and accurately identify the alarm type, such as smoke, intrusion, etc., and trigger the corresponding security warning mechanism, such as sending an alarm, starting an emergency plan, etc.; 2) Based on a real video stream, copy and perform diversified configuration processing to obtain multiple video streams related to the real video stream, and then input the real video stream and the multiple video streams obtained by diversified processing into the system under test, verify whether the system under test can correctly parse and display the received video stream, including whether the video resolution, frame rate, bit rate and other parameters match the system settings, and whether the video picture is clear and smooth when previewing multiple video streams at the same time, without obvious delay or freeze; 3) After the alarm signal stream and the alarm video stream are input into the system under test, verify whether the system under test can correctly associate the alarm signal stream with the corresponding alarm video stream, and when an alarm occurs, it can automatically call the associated video surveillance to view the situation at the alarm site in real time, so as to test the system's response mechanism and information integration capabilities in emergency situations.

[0083] Step S312: when the test result indicates that the alarm video stream retrieved by the security system based on the alarm signal stream meets the preset video type, it is determined that the security system meets the preset test requirements.

[0084] Specifically, it is necessary to test the system under test from the above three perspectives. If the test results all indicate that the system under test can meet the corresponding requirements, that is, after the alarm signal stream is input into the system under test, the system under test can quickly and accurately identify the alarm type, such as smoke, intrusion, etc., and trigger the corresponding security warning mechanism, such as sending an alarm, initiating an emergency plan, etc.; after the alarm video stream is input into the system under test, the system under test can correctly parse and display the received alarm video stream, including whether the video resolution, frame rate, bit rate and other parameters match the system settings, and whether the video picture is clear and smooth without obvious delay or freeze; after the alarm signal stream and the alarm video stream are input into the system under test, the system under test can correctly associate the alarm signal stream with the corresponding alarm video stream, and when an alarm occurs, it can automatically call the associated video surveillance to view the situation at the alarm scene in real time, then it can be considered that the performance and functions of the security system meet the requirements.

[0085] From the above, it can be seen that through the technical solution provided by the above embodiment of the present invention, the alarm signal simulation device can be controlled to parse the received test data to obtain the preset video type corresponding to the test keyword and the test data, wherein the test data is data describing the preset alarm scene, and the security system is used to monitor and warn of danger in the target monitoring area; the alarm signal simulation device is controlled to generate an alarm signal stream according to the test keyword; the alarm signal stream generated by the alarm signal simulation device is transmitted to the video simulation device by using the signal and video fusion module, so as to control the video simulation device to retrieve the real video stream matching the alarm signal stream according to the alarm signal stream, wherein the real video stream is the video collected by the image acquisition device that has a communication connection relationship with the video simulation device; the video simulation device is controlled to generate a multi-channel configuration video based on the real video stream Stream, wherein the configured video stream is a video obtained by configuring according to the real video stream using a preset algorithm; the alarm signal stream and the alarm video stream are input into the security system to simulate the preset alarm scene and obtain the test result, wherein the alarm video stream includes: the real video stream and the configured video stream; when the test result indicates that the alarm video stream retrieved by the security system based on the alarm signal stream meets the preset video type, it is determined that the security system meets the preset test requirements, and the purpose of testing the security system by parsing the test data input by the user to obtain the alarm signal stream, and retrieving and generating the corresponding alarm video stream is achieved, and a large number of configured video streams are generated based on a small number of real video streams to enrich the number of video streams, thereby achieving the technical effect of effectively simulating the test of the security system, thereby improving the test efficiency and accuracy.

[0086] Therefore, the technical solution provided by the above-mentioned embodiment of the present invention solves the technical problem in the related art that when testing the security system, a large number of camera devices cannot be deployed for data collection and there are many types of test scenarios, resulting in the inability to effectively perform simulation, thereby affecting the test efficiency and accuracy.

[0088] In the case where the alarm signal simulation device and the multi-channel video simulation device cooperate to test the security system, a fusion module of an alarm sensor simulation device (alarm signal simulation device) and a multi-channel video simulation device can be used to implement the analysis and generation of the alarm signal stream and the alarm video stream, such as Figure 8 As shown, the specific implementation steps are as follows: 1) Alarm sensor multi-signal joint simulation: The alarm signal simulation device uses a directed graph data structure to maintain the linkage relationship between multiple types of alarms. The alarm type linkage relationship is as follows: Fig. 9 As shown in the figure, all graph nodes are different alarm types, where A->B, weight 1 means when A alarm occurs, B alarm will also occur; A->H, weight 0 means there is no association between A and H, and A and H alarm signals will not be generated at the same time; for example, when a smoke alarm occurs, a video occlusion alarm will also occur. When the simulator simulates the alarm signal according to the key field, it finds the alarm type node that needs to be simulated, and then uses the traversal algorithm to traverse all alarm types associated with this alarm type and record the weights. At the same time, it simulates all alarm type signals with a weight of 1 in the traversal path of the current alarm type, and sends the multi-type alarm signals to the signal queue after protocol standardization; 2) Alarm signal synchronization video terminal simulation: parse the multi-type alarm signal message, and supplement the video request related parameters according to the message content, generate the video sensor simulation device request message and send it to the message queue. The video sensor simulation device receives and processes the video stream information corresponding to the generated alarm information.
