[0024] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present invention and the above-mentioned drawings are intended to distinguish the objects referred to. For schemes with a sequential flow, this terminology does not necessarily need to be understood as describing a specific order or sequence. For schemes with device structures, this terminology does not distinguish between importance, positional relationships, etc.

[0026] In addition, the terms "including", "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that have been explicitly listed, but may also include other steps or units that are not explicitly listed but are inherent to these processes, methods, products or apparatuses, or steps or units that are added based on further optimization solutions conceived by the present invention.

[0027] like Figure 1 As shown, a circuit for restarting a UAV terminal control system includes a programmable logic controller (PLC), a time relay, an intermediate relay, and a terminal block:

[0028] The input end of the time relay is connected to the output end of the PLC, and the output end of the time relay is connected to the second coil of the intermediate relay;

[0029] The first coil of the intermediate relay is connected to the positive electrode of the 24V power supply, the normally open contact of the intermediate relay is connected to the neutral line of the 220V AC power supply, and the normally closed contact of the intermediate relay is connected to the live line of the 220V AC power supply;

[0030] The first terminal of the terminal block is connected to the normally open contact of the intermediate relay, the second terminal of the terminal block is connected to the normally closed contact of the intermediate relay, and the third terminal of the terminal block is connected to the power line of the abnormal component.

[0031] It should be noted that the utility model is used to control the power-off and self-restart of abnormal components in the control system. When the abnormal components in the control system need to be powered off and restarted, the corresponding abnormal components can be powered off by remotely sending a control signal, and the abnormal components can be automatically powered on after a certain period of power outage, thereby achieving the purpose of restarting the abnormal components.

[0032] It should be noted that the utility model is based on a complete set of UAV terminal control systems, and optimizes and modifies the original UAV terminal control system, and connects the power supply of abnormal components that need to be powered off and restarted separately to a terminal block that can control power on and off.

[0033] When the distribution box is powered on, it can normally power all components of the control system. When the control system unit in the entire power supply system needs to be powered off and restarted, the entire control system unit can be restarted through remote control. There is no need to power off and restart each submodule separately. A single-click command can achieve the function of powering off and restarting all control system units.

[0034] In this embodiment, the output point of the PLC is connected to the start control pin of the time relay. The common contact of the time relay is connected to the negative voltage of 24V. The normally closed point corresponding to the common contact is connected to the coil A2 of the intermediate relay. The coil A1 of the intermediate relay is connected to the positive voltage of 24V. The control of the intermediate relay disconnection and delayed pickup is achieved, thereby realizing the function of power-off self-restart. After establishing the above connection, AC220V is drawn out, and the live and neutral wires are respectively connected to two different common contact pins of the intermediate relay. Then, the live and neutral wires are respectively drawn out from the normally open contacts corresponding to the common contacts of the intermediate relay and connected to the terminal block. When in use, the power cord of the device that needs to be restarted after power outage is connected to the terminal block. In this way, when the system needs to be restarted, it is only necessary to issue a system restart command, and the corresponding device can be powered off. After 10 seconds of power off, the power is restored. The power-on time of the system after power off can be set as needed.

[0035] The utility model provides a circuit for restarting a drone terminal control system, comprising a programmable logic controller (PLC), a time relay, an intermediate relay, and a terminal block: the input end of the time relay is connected to the output end of the PLC, and the output end of the time relay is connected to the second coil of the intermediate relay; the first coil of the intermediate relay is connected to the positive pole of a 24V power supply, the normally open contact of the intermediate relay is connected to the neutral line of a 220V AC power supply, and the normally closed contact of the intermediate relay is connected to the live line of the 220V AC power supply; the first terminal of the terminal block is connected to the normally open contact of the intermediate relay, the second terminal of the terminal block is connected to the normally closed contact of the intermediate relay, and the third terminal of the terminal block is connected to the power line of an abnormal component. The present application forms an automated power-off restart circuit through the coordinated control of the PLC, the time relay, and the intermediate relay, thereby realizing automatic power-off restart of abnormal components in an unattended state, with high restart efficiency and effectively reducing the risk of misoperation.

[0036] Specifically, the present invention triggers a time relay via a remote control signal from a PLC, automatically disconnecting and restoring power to abnormal components within a preset time, eliminating manual operation and improving system restart efficiency. The present invention simplifies the control process, eliminating the need to manually locate and operate specific abnormal components, effectively avoiding the risk of power outages to other components due to manual misoperation and ensuring the normal operation of the control system. Furthermore, the present invention can automatically respond to abnormal situations without human monitoring, enabling remote automatic restart of abnormal control system components, meeting the needs of drone terminals as they gradually move towards automated and unmanned management.

[0037] In one embodiment of the present application, the PLC controls the intermediate relay to power off through the time relay, and controls the intermediate relay to power back on after a preset time.

[0038] In this embodiment, the PLC uses a time relay to control the intermediate relay to power off and then restore power after a set time. This control method ensures that the device can precisely control the power-off and restart timing after detecting an anomaly. Compared to traditional manual operation, the PLC can automatically control the time relay, significantly reducing the errors and delays caused by manual operation. This design not only improves the system's response speed but also reduces the risk of manual intervention, making the system more suitable for unmanned management scenarios and improving the automation level and stability of the equipment.

[0039] In one embodiment of the present application, the preset time is 10 seconds.

[0040] It should be noted that the preset time can be optimized by maintenance personnel according to actual conditions to adapt to the needs of different types of equipment, thereby ensuring stable recovery of the system after a power outage. This embodiment does not make specific limitations on this.

[0041] In this embodiment, a precisely set delay ensures that the restart process is completed in the shortest possible time, while also avoiding unnecessary power outages. This precise time control is crucial to improving system reliability, effectively preventing abnormal components from being mistakenly identified as requiring a restart due to brief faults, further enhancing the system's security and intelligence.

[0042] In one embodiment of the present application, the normally open contact of the intermediate relay and the normally closed contact of the intermediate relay are used to control the on and off of the power supply to the abnormal element.

[0043] In this embodiment, the switching between normally open and normally closed contacts enables control of power supply to abnormal components, ensuring orderly recovery of the device after a power outage. This design not only facilitates control of the power-on and power-off states of abnormal components but also enables remote control through simple contact switching, enhancing the system's automation capabilities. The combination of normally open and normally closed contacts adds flexibility to the overall circuit, enabling rapid switching based on actual conditions, effectively ensuring the normal operation of the control system.

[0044] In one embodiment of the present application, the time relay includes a normally open contact and a normally closed contact. The normally open contact of the time relay is used to start the power-off operation of the intermediate relay, and the normally closed contact of the time relay is used to restore the power supply of the intermediate relay after a preset time.

[0045] In this embodiment, the normally open contact of the time relay is used to initiate the power-off operation of the intermediate relay, while the normally closed contact of the time relay is used to restore power after a preset time. This design ensures that the time relay can precisely control the on and off operation of the intermediate relay, achieving an automated control process. The normally open and normally closed contacts of the time relay can quickly disconnect and restore power through contact switching, allowing the system to quickly return to normal without human intervention, meeting the automated operation requirements of the drone terminal and further improving the system's reliability and responsiveness.

[0046] In one embodiment of the present application, the output end of the PLC is connected to the control pin of the time relay so as to start the time relay through the control signal of the PLC.

[0047] like Figure 2 As shown, pins 2 and 10 of the time relay are the power supply interfaces for the time relay, used to power the time relay. Pin 10 is connected to the 24V positive supply, and pin 2 is connected to the 24V negative supply. Pins 1, 3, and 4 are the time relay's normally open and normally closed contacts. Pin 1 is the common point of the time relay contacts. Pins 1 and 3 form a normally open auxiliary contact group, and pins 1 and 4 form a normally closed auxiliary contact group. Pins 8, 9, and 11 are the time relay's other normally open and normally closed contacts. Pin 11 is the common point of the time relay contacts. Pin 11 and pin 9 form a normally open auxiliary contact group, and pin 11 and pin 8 form a normally closed auxiliary contact group. Pins 6 and 7 are the time relay control pins. Pin 7 is connected to the 24V negative supply, and pin 6 is connected to the PLC output. When the PLC output terminal outputs a signal, the time relay contact operates and pins 1 and 4 are disconnected, the intermediate relay coil loses power, and the equipment is powered off. After a delay of 10S (the time can be set according to actual needs), the time relay restores pins 1 and 4 to attract, and the intermediate relay is energized to restore power to the equipment, thereby realizing the function of power-off restart of the equipment.

[0048] In this embodiment, by connecting the PLC output to the control pins of a time relay, the system can precisely control the time relay's activation time and contact state, achieving precise delay operation. This connection ensures circuit automation through control signals, enabling the control system to respond promptly and accurately to abnormal situations. In unattended operation, the PLC's control signal triggering mechanism provides reliable protection for remote device restarts, helping to improve the overall efficiency and stability of the system.

[0049] In one embodiment of the present application, there are multiple third wiring terminals, and each of the third wiring terminals is connected to a power line of the abnormal component.

[0050] In this embodiment, multiple third terminals can be connected to different abnormal components, enabling the system to centrally manage the power supply of multiple abnormal components. This design allows for simultaneous restart of multiple key components, significantly improving system maintenance efficiency. Furthermore, this structure provides independent power supply channels for different components, preventing multiple components from losing power due to the same abnormality, further ensuring the normal operation of the system. It is suitable for application scenarios where multiple devices are collaboratively managed in drone terminals.

[0051] In one embodiment of the present application, the output end of the time relay is connected to the second coil of the intermediate relay through a circuit breaker.

[0052] like Figure 3 As shown, connect the 220V power supply to the top of circuit breaker D8QF1. Lead the power lines from the bottom of the circuit breaker to pins 11 and 21 of the intermediate relay. Lead the power lines from pins 14 and 44 of the intermediate relay to contact A4C 4 on the terminal block XT1.27-1 and XT1.28-1. Connect the PLC power supply to XT1.27-3 and XT1.28-3, and the industrial computer power supply to XT1.27-4 and XT1.28-4.

[0053] In this embodiment, the output of the time relay is connected to the intermediate relay via a circuit breaker, adding a protective layer to the circuit. When an abnormality occurs in the system, the circuit breaker automatically disconnects, preventing damage to the equipment from circuit overloads or short circuits. The inclusion of the circuit breaker improves circuit safety and ensures stable operation in complex environments. Especially in unattended scenarios, the protection provided by the circuit breaker further enhances the system's self-protection capabilities, reduces the need for external intervention, and improves the circuit design.

[0054] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
