[0024] In the figure, 1-main control computer, 2-relay control module, 3-intelligent PDU module, 4-manual remote switch, 5-acquisition module, 6-integrated power distribution management software. DETAILED DESCRIPTION

[0025] The present invention is achieved through the following technical solutions.

[0026] This integrated power distribution management system has been successfully applied to a ground iron bird test bench for a certain type of aircraft, and supported the completion of the aircraft's research and development and airworthiness verification tests.

[0027] like Figure 1 As shown, a comprehensive power distribution management system for an iron bird station includes a main control computer 1, a relay control module 2, an intelligent PDU module 3, a manual remote switching module 4, an acquisition module 5, and a comprehensive power distribution management software 6. In this embodiment, the main control computer 1 adopts a workstation, configured with a CP-118U serial port card, with an 8-way RS485 serial communication interface, a mouse and keyboard, and is arranged in a test control room. The relay control module 2 adopts an RS485 serial bus communication relay module. In the example application, four 16-channel relay modules are used according to the number of power distribution control channels, and contactors of appropriate specifications are used to realize remote control of AC380V, AC220V, and DC28V power distribution. The intelligent PDU module 3 uses an RS485 serial bus communication intelligent PDU module, the power distribution interface is a national standard 16A socket, the power of a single interface is 2.5kW, and the standard 1U chassis size is placed in or near the test equipment cabinet to realize the distributed test equipment power distribution control. In this example, a total of 6 intelligent PDU modules are used to support 48-way power distribution control, which are distributed in the front fuselage equipment compartment, rear fuselage equipment compartment and middle fuselage area of ​​the iron bird station. Other equipment can be connected to the power distribution control system through standard national standard plugs. The manual remote switching module 4 is arranged on the front panel of the first-level distribution cabinet or the second-level distribution cabinet. It uses a combination of knob switches and push button switches to realize the switching of local and remote distribution control. It also has an emergency stop switch module. In this example, the 380V main distribution cabinet and the 28V DC power distribution cabinet are both installed with manual remote switching modules 4 to facilitate local manual operation during installation and debugging. The acquisition module 5 uses a voltage and current module for RS485 serial bus communication, which is distributed and installed in the primary and secondary distribution cabinets, and is equipped with voltage sensors and current sensors to realize the acquisition and upload of voltage and current signals of each power distribution. In this example, three types of voltage sensors and current sensors, such as AC three-phase 380V, AC 220V, and DC 28V, are selected to realize the data acquisition of equipment power supply and airborne system power supply. The comprehensive power distribution management software 6 uses a graphical software interface to realize functions such as user management, power distribution control, power distribution status monitoring, and system configuration.

[0028] The integrated power distribution management software 6 implements authority management through the user management interface, sets users with different authorities, and prevents illegal operations and parameter changes.

[0029] The integrated power distribution management software 6 realizes power distribution control through the graphical control of the power distribution control interface, and divides the interface into AC380V power distribution control area, PDU power distribution control area, and airborne equipment 28V power distribution control area. The interface is simple and clear, and the graphical operation and feedback are intuitive, which effectively reduces the difficulty of operation and improves the efficiency of power distribution control in the test. The emergency protection interface supports the manual emergency operation of the software, which can realize the emergency power-off operation of the test equipment and the emergency power-off operation of the 28V power supply of the airborne equipment. At the same time, combined with the protection parameter setting, automatic emergency protection power-off can be realized. The combined / sequential power distribution control interface combines commonly used power-on devices, and configures them according to the timing requirements such as the power-on and power-off sequence, the power-on and power-off time interval, and realizes one-key combined power-on. The combined / sequential power distribution can establish 4 groups of power distribution settings for the test equipment power distribution and the airborne 28V DC, meeting the needs of various test conditions and greatly simplifying the power distribution control operation.

[0030] The power distribution monitoring interface displays the voltage and working current status signals of all power distribution, displays the regions according to different power types, and provides color warnings, which greatly facilitates the monitoring of test personnel. The power distribution monitoring interface can also store power distribution data locally and upload relevant information to the test network in real time via Ethernet.

[0031] The power distribution parameter configuration interface realizes the settings of 28V DC power supply parameters, current alarm threshold, current limiting protection, etc., which improves the informatization level of the entire system and the intelligence level and improves the power distribution safety of the system.

[0032] The protection scope of the present invention is not limited to the above-mentioned embodiments. Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the scope of the present invention. If these changes and modifications fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include these changes and modifications.
