[0024] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions in the present utility model will be clearly and completely described below with reference to the accompanying drawings in the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without making creative efforts shall fall within the protection scope of the present utility model.
[0025] It should be noted that in the description of the embodiments of the present utility model, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitations, an element defined by the statement "including one..." does not exclude the existence of additional identical elements in the process, method, article or device including the element. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0026] Figure 1 It is a schematic structural diagram of the power supply program control and monitoring system provided by the present utility model, as Figure 1 shown. The system includes: a remote control console, a network switch and a transmitting control console; the transmitting control console includes a test host and a programmable power supply; the remote control console is communicatively connected to the test host through the network switch, and the test host is communicatively connected to the programmable power supply.
[0027] Among them, the device under test may be an aircraft; the test host and the programmable power supply may be communicatively connected through an RS232 interface; the programmable power supply may be a programmable power supply for converting alternating current to direct current, that is, an AC / DC programmable power supply.
[0028] The remote control console communicates bidirectionally with the test host through a network switch; the operator can input control commands through the human-machine interface of the remote control console, such as setting parameters such as the output voltage and current of the power supply. The remote control console encapsulates the multi-channel voltage and current information of the programmable power supply that needs to be controlled into a control command and sends it to the test host of the launch control console in the form of a network data packet, and receives the feedback data of the programmable power supply forwarded from the test host and displays it in real time on the graphical software interface.
[0029] The network switch connects the remote control console and the test host at the network level to realize the forwarding of data packets; specifically, the network switch can automatically identify and forward data packets to ensure that the instructions and feedback data can reach the destination accurately.
[0030] The main task of the network switch is to forward the data packet to the correct port according to the destination MAC address of the data packet. By dividing the VLAN (Virtual Local Area Network), the network switch can limit the scope of broadcast traffic and reduce the risk of broadcast storms.
[0031] In this system, the network switch connects the remote control console and the test host through Ethernet to form a closed local area network; when the remote control console sends a control command in the form of a network data packet, the network switch forwards the data packet to the test host according to the destination MAC address; similarly, when the test host sends feedback data, the network switch will also forward these data packets to the remote control console.
[0032] The network switch in this utility model connects the remote control console and the test host at the network level, and realizes the fast transmission of control commands and feedback data through an efficient data packet forwarding mechanism, which is crucial for improving the response speed and overall performance of the system; further, the network switch helps to reduce the latency in the whole system; by setting up access control lists (ACLs), the network switch can increase the security of the system and prevent unauthorized access.
[0033] The remote control console and the test host are physically connected to the same network switch through Ethernet cables; a reliable connection is established through the three-way handshake (socket) of the TCP / IP protocol. After the connection is established, the remote control console can send control commands or data to the test host through this connection; the test host receives the commands or data, executes the corresponding operations, and then sends the feedback results back to the remote control console. In this process, in order to ensure the reliability of data transmission, an error code retransmission mechanism (such as ARQ Automatic Repeat Request) is usually used. If the receiving party detects a data packet error or does not receive an acknowledgment within a certain period of time, it will request the sending party to re-send the data packet.
[0034] After the data transmission is completed, the connection needs to be disconnected to release resources. Disconnecting the connection is usually also done through a series of handshake signals, which will not be elaborated here. This communication method based on the TCP / IP protocol ensures the reliability and sequentiality of data transmission and is very suitable for application scenarios such as remote control and monitoring.
[0035] The test host of the console serves as a medium between the remote console and the AC / DC programmable power supply, communicates with them respectively, receives control instructions in the form of network data packets from the remote console, and converts them into serial instructions that the programmable power supply can recognize; at the same time, it receives the feedback data of the programmable power supply and forwards it to the remote console through the network switch.
[0036] Specifically, the test host parses the received network data packets, converts them into corresponding serial instructions (RS232 serial port data frame instructions), and sends them to the programmable power supply through the serial interface; at the same time, it listens to the feedback data of the programmable power supply, repackages it into network data packets, and sends them back to the remote console through the network switch.
[0037] The programmable power supply parses the received serial port instructions, automatically adjusts the power supply voltage and current through the internal DSP software of the power supply, and sends the current parsed real-time voltage and current data to the test host of the console through the serial port data packet, that is, sends it to the test host in the form of feedback data.
[0038] The working mode of the AC / DC programmable power supply has two modes: local and remote. In the local mode, turn the programmable power supply switch to the local mode, and the control knob outputs the corresponding voltage and current; in the remote mode, the server side needs to output the enable and parameter commands to the programmable power supply through asynchronous RS232 to control the power supply to output the corresponding voltage and current values. Among them, the instruction types are divided into 4 types: enable, disable, power supply parameters, and voltage setting. When the data frame is transmitted, the low byte comes first, and then the high byte. The serial port data format is 10 bits per character, including 1 start bit, 8 data bits (the least significant bit is in the front, and the most significant bit is in the back), 1 stop bit, and no parity bit. The method of frame header reading and checksum judgment is used to ensure the correctness of communication.
[0039] Figure 2 is a schematic flow chart of the operation using the power supply programmable and monitoring system provided by the present invention, as Figure 2 shown, including but not limited to the following steps:
[0040] S1. Turn on the power supply switch of the AC / DC programmable power supply to make it in the working state;
[0041] S2. The remote console encapsulates the multi-channel voltage and current information that needs to control the programmable power supply into control instructions and sends them to the console through the network switch in the format of network data packets;
[0042] S3. The test host of the control console analyzes the obtained network data packets, encapsulates them into corresponding RS232 serial port data frame instructions, and sends them to the AC / DC programmable power supply.
[0043] S4. The AC / DC programmable power supply analyzes the received serial port instructions, automatically adjusts the power supply voltage and current through the internal DSP software of the power supply, and sends the current real-time voltage and current data parsed through the serial port data packet to the test host of the control console.
[0044] S5. The test host of the control console encapsulates the obtained real-time voltage and current data into the format of network data packets and sends them to the remote control console through the network switch.
[0045] S6. The remote control console analyzes the obtained network data packets, and interprets and displays the valid power supply information in real time on the graphical software interface. The working status of the power supply is displayed on the human-machine interface.
[0046] The power supply programmable control and monitoring system provided by the present utility model has the following remarkable advantages:
[0047] (1) More efficient communication: Using the network switch as the communication hub can support high-speed data transmission, making remote control more timely and accurate. Data communication through Ethernet has higher bandwidth and better compatibility compared to traditional serial communication methods (such as RS-232).
[0048] (2) More accurate monitoring: The programmable power supply can provide accurate voltage and current outputs, and can feedback the status information to the test host in real time. The test host can collect and analyze these data for real-time monitoring, which helps to quickly identify problems and faults.

[0050] (4) Enhanced security: The network switch can set access permissions, increasing the security of the system.
[0051] (5) Improved reusability: Through standardized interfaces and communication protocols, each module in the system can be reused in multiple applications, improving resource utilization.
[0052] In summary, the power supply programmable control and monitoring system provided by the present utility model has higher integration, flexibility, scalability, and cost-effectiveness compared to traditional control systems. At the same time, it also improves the security of the system and the convenience of maintenance.
