[0022] The following further elaborates in detail on a platform detection system proposed by the present invention in combination with the accompanying drawings and specific embodiments. According to the following description, the advantages and features of the present invention will be clearer. It should be noted that the accompanying drawings are all in a very simplified form and use non-precise scales, only for the purpose of facilitating and clearly assisting in explaining the purpose of the embodiments of the present invention.

[0023] The present invention provides a platform detection system, and its system principle is as Figure 1 shown, including two parts: hardware and software. The hardware uses a NI system (i.e., an equivalent simulation system) to collect various types of signals and control the IO quantity in real time; the software uses Labview programming, calls the labviewFPGA toolkit for signal simulation, equivalence, modular program writing, and realizes the design of the test process database, greatly shortening the software development cycle, effectively simplifying the reuse of software modules and the modification of the test process database for different models and different devices; applying historical real data for data playback is convenient for fault reproduction during the operation of the detection platform.

[0024] Figure 2 It is the connection diagram of the platform detection system. For different devices and different measurement and control systems, through the general interface adapter, the work complexity at the test equipment end is greatly simplified, and the test anomalies caused by human factors are reduced; the consistency with the interface is unified, making the test integrity optimal. The general interface adapter mainly completes signal transfer and signal conditioning, including level conversion, 24V power supply for the discrete I / O card, and signal adaptation; it mainly completes the communication interconnection between the measurement and control system and the equivalent simulation system, forwards the main control instructions of the measurement and control system to the equivalent simulation system, and forwards the signal status between the equivalent simulation systems to the main control unit of the measurement and control system.

[0025] Figure 3 It is the modular software design of the platform detection system. The host computer software is designed using the labview-DQMH software architecture, mainly classifying the hardware functions, including control types (discrete output, analog output), acquisition types (discrete input, analog input), and bus types (RS485\RS232, CAN, LAN); the process control module obtains the hardware configuration information and test process information from the database during initialization and stores them in the cache for convenient reading and writing during the test process; the control interface mainly completes functions such as hardware initialization, start and end of the test process, and data recording; the configuration interface includes whether the device is equivalent, and the administrator permission can cut, modify, and add product test processes; the status display module displays the current parameters and status of each device in real time, and performs corresponding actions or prompts for abnormal status parameters according to the protocol; the user interface integrates and displays each sub-module to improve the high cohesion and low coupling degree of the software.

[0026] The classification of the test process information mainly includes test process number, test process, control instruction, excitation value type, condition, excitation value, determination, and jump. The test process number and test process are only used for prompting information; the control instruction is which steps and operations should be executed after the test system receives the instructions from the measurement and control system; the excitation value type has information such as initialization, delay, acquisition, and setting. The process control module corresponds one-to-one with the excitation value type in the test process information, and the reserved fields are used for new functions; the condition and excitation value represent the signal name and value for setting or acquisition; the determination is used for waiting or jump execution.

[0027] After the measurement and control system sends an action instruction through the communication bus, the communication bus at the test equipment end is only responsible for receiving data and commands. The data parsing sub-module in the process control module is specifically used to extract node and sub-node information, and then search for the extracted node and sub-node information with the control instructions in the test process information, and then perform corresponding operations according to the excitation value type, condition, excitation value, and jump in the test process information.

[0028] Figure 4 It is the test flow chart of the platform detection system. During the actual test process, the test equipment acts as a slave, and the measurement and control system is the initiator. After receiving the instructions from the measurement and control system, the test equipment performs corresponding actions and status feedback. When the status of all test equipment is ready, the test software starts, selects the simulation equipment model and reads the test process of this model. After the test equipment is initialized correctly, parameter configuration is carried out, such as manual test or automatic test, whether the test equipment is equivalent, etc. After clicking the start test button, the platform detection system waits for the measurement and control system to initiate relevant test items. The test equipment software can display the current test process and the current status of each signal in real time; it can replay historical data. In order to facilitate the reproduction of faults, during the replay of historical data, the status of a certain signal can be manually changed to observe the overall change of the system.

[0029] Through the characteristics of software function modules, the present invention realizes different functions corresponding to different modules, and different functions are realized through different modules. The modules are independent of each other, which is convenient for the expansion and trimming of functions; in order to detect whether the function performance of a certain platform is normal and to replay and analyze the data during the physical test process, at the same time, the software is written using modular programs and the test process database design is realized, which greatly shortens the software development cycle and effectively simplifies the software modules of different measurement and control system devices and the reuse of test processes; applying historical real data for data replay is convenient for detecting the reproduction of faults during the operation of a certain platform.

[0030] The above description is only a description of the preferred embodiments of the present invention, and does not limit the scope of the present invention in any way. Any changes and modifications made by those of ordinary skill in the field of the present invention based on the above disclosure shall fall within the protection scope of the claims.
