Description

Real-time display and recording method for key power distribution signals Technical Field The invention belongs to the field of industrial field testing, and particularly relates to a real-time display and recording method for key power distribution signals. Background In the design and implementation of the ground test initiation control system, the power distribution control of the system instrument equipment is usually controlled by the ground test initiation control system, and specifically comprises the power supply state control of equipment such as an arrow-mounted computer, a ground inertial measurement unit and the like. However, hardware devices are limited by their physical lifecycle, requiring device retirement and replacement when MTTF (Mean Time to Failure) thresholds are reached. Because the actual accumulated power distribution time length is obviously lower than the theoretical value, in order to optimize the production operation and maintenance cost, it is particularly important to display and record the actual live working time of key equipment of the system in real time. Disclosure of Invention The invention aims to provide a recording method for realizing a key equipment power distribution process based on an XML dynamic parameterized configuration file, which is used for displaying key power distribution signals in real time through a GUI man-machine interaction interface, wherein the power distribution time length and the accumulated power distribution time length used so far in the test process are convenient for system staff to grasp equipment states and test related progress in real time, test state confirmation, fault investigation and the like, so that the dual requirements of engineering reliability and cost control are met, and data support is provided for equipment life prediction and preventive maintenance. The invention provides a recording method for realizing a key equipment power distribution process based on an XML dynamic parameterized configuration file, which comprises the following specific steps: step 1, modeling a key signal; (1) Based on the tree structure design domain specific language Extensible Markup Lauguage, the signal metadata is described by using custom tags (such as "< SignalRecord >") and attribute sets ("SignalName"、"test_id"、"model"、"connect_time"、"disconnect_time"、"duration_time"、"totalDuration_time", etc., so as to form an XML configuration file. (2) The signal attribute set implements a "K, V" index using a hash map (HashMap), where Key is the signal Static Identifier (SIGNALNAME) and Value is the signal entity object (SIGNALENTITY) that contains the dynamic timing attributes. (3) Through XML serialization/deserialization, the read-write conformity of the configuration file is ensured. Step 2, initializing software: (1) Configuration file loading and objectification. The configuration file is analyzed when the software is started, a thread safety set m_ MAPTIMEKEEPING of the type of ConcurrentHashMap < String, SIGNALENTITY >' is constructed, and the instantiation of the signal entity object is completed. (2) The historical state is restored. Traversing m_ MAPTIMEKEEPING, extracting each signal entity object, and taking the field 'totalDuration _time' value as an initial accumulated distribution time reference value of each signal. (3) View layer binding. Based on the MVC mode, the corresponding Observer control (Observer Widget) is retrieved in the UI component registry by the signal name "SIGNALNAME" to establish the data-view bidirectional binding. (4) Time unit normalization. The policy mode (STRATEGY PATTERN) is used to implement time unit conversion. (5) And (5) redrawing the interface. And (3) according to the display unit requirement of the system on the distribution time of each signal, combining the steps (2), 3 and 4), converting the second-level time stamp of the initial accumulated distribution time of each signal into a formatted character string such as hours/minutes/seconds and refreshing each UI component. (6) And (5) managing a timer. A high precision timer is created based on the thread pool, and each 'SIGNALNAME' is associated with an independent timing instance to support millisecond-level time slice polling. Step 3, signal state machine and event processing: according to the attribute "model" of the signal entity object, the signal "on" and "off" times are recorded in the following two ways respectively. (1) The signal automatically turns on/off mode. In the automatic test framework, if the power distribution state of the equipment is controlled by the test flow drive, an event-driven mode is adopted to monitor test step events (such as 'ON_CONNECT' and 'ON_DISCNECT' events of corresponding equipment), a signal state change callback function is injected through a Hook mechanism, and the attributes 'connect_time' and 'disconnect_time' of a signal entity object are recorded. (2) The signal manually turns on/off mode. On the basi
