Description

Technical Field

[0001] This invention belongs to the field of underwater unmanned vehicle technology, specifically relating to a magnet-based underwater unmanned vehicle power switch control device and control method. Background Technology

[0002] The power switch is an electronic component that powers and shuts down an underwater unmanned vehicle (UAV). Traditionally, the power switch for an UAV is a mechanical rotary switch installed through a hole drilled in the vehicle. The power is controlled by rotating the mechanical rotary switch with a special key. However, this traditional method requires a hole to be pre-drilled in the UAV's outer shell, which affects the vehicle's appearance and increases the risk of water leakage during underwater operation. In addition, the frequent switching of the mechanical rotary switch can easily damage it, resulting in a short service life. Summary of the Invention

[0003] In view of this, the present invention provides a magnet-based underwater unmanned vehicle power switch control device and control method. The device does not require drilling holes on the underwater unmanned vehicle, nor does it require a special switch key. It can realize the switching control of the underwater unmanned vehicle power supply with only a magnet, and the on and off of the relay coil is controlled by the engagement of the reed switch, resulting in a long service life.

[0004] This invention is achieved through the following technical solution:

[0005] A magnet-based power switch control device for an underwater unmanned vehicle, which controls the power supply to power on or off the system's central control unit.

[0006] The control device includes: a reed switch board and a relay self-locking circuit board encapsulated in a control box, and a magnet located outside the control box; the relay self-locking circuit board is electrically connected to the power supply, the system central control unit and the reed switch board respectively; the magnet is used to control the engagement of the reed switch on the reed switch board;

[0007] The reed switch board includes two reed switches, namely reed switch one and reed switch two. When reed switch one is triggered, it sends a power-on command to the relay self-locking circuit board. When reed switch two is triggered, it sends a power-off command to the relay self-locking circuit board. The relay self-locking circuit board controls the circuit between the power supply and the system central control unit to be connected or disconnected according to the received power-on or power-off command. When the circuit between the power supply and the system central control unit is connected, the power supply is continuously supplied, i.e., the power is on. When the circuit between the power supply and the system central control unit is disconnected, the power supply is interrupted, i.e., the power is off.

[0008] Furthermore, the reed switch one and reed switch two are arranged in a straight line; when the magnet moves from the side where reed switch two is located to the side where reed switch one is located, reed switch two is triggered to close first, and then reed switch one is triggered to close, so the power-on command triggered later can be executed, and the short-circuit signal of the power-on command is sent to the relay self-locking circuit board; when the magnet moves from the side where reed switch one is located to the side where reed switch two is located, reed switch one is triggered to close first, and then reed switch two is triggered to close, so the power-off command triggered later can be executed, and the short-circuit signal of the power-off command is sent to the relay self-locking circuit board.

[0009] Furthermore, the relay self-locking circuit board includes three relays, namely relay K1, relay K2 and relay K3;

[0010] When a power-on command is received, the coil of relay K1 is energized and forms a self-locking mechanism with the trigger-closed contact, ensuring that the coil of relay K2 remains energized, thereby ensuring the circuit between the power supply and the system's central control unit and achieving continuous power supply. When a power-off command is received, the coil of relay K3 is energized, triggering the normally closed contact to open, de-energizing the coil of relay K1 and releasing the self-locking mechanism, thereby de-energizing the coil of relay K2, and thus disconnecting the circuit between the power supply and the system's central control unit, achieving power supply interruption.

[0011] Furthermore, the specific electrical connections between the relay self-locking circuit board, the power supply, the system central control unit, and the reed switch board are as follows:

[0012] The output of pin 1 of the reed switch one is a "switch on" signal, the output of pin 1 of the reed switch two is a "switch off" signal, and the output of pin 2 of the two reed switches is a "switch COM" signal after being connected by wire A.

[0013] The relay K1 includes: a relay coil K1A and its contacts K1B and K1C; the relay K2 includes: a relay coil K2A ​​and its contacts K2B; the relay K3 includes: a relay coil K3A and its contacts K3B.

[0014] The positive terminal of the power supply is connected to one end of the contact K2B of the relay K2 via wire B, and the other end of K2B is connected to the positive terminal of the system central control unit; the ground terminal of the power supply is connected to the negative terminal of the system central control unit via wire C.

[0015] One end of the coil K1A of relay K1 is connected to pin 1 of reed switch 1 via wire D. The other end of K1A is connected to one end of the normally closed contact K3B of relay K3. The other end of K3B is connected to point X via wire B.

[0016] One end of the coil K3A of relay K3 is connected to pin 1 of reed switch 2, and the other end of K3A is also connected to wire B at point X through wire E;

[0017] One end of the coil K2A ​​of relay K2 is connected to the wire A between pins 2 of the two reed switches via wire F. Wire F and wire C intersect at point Y. The other end of K2A is connected to one end of the contact K1C of relay K1. The other end of K1C is connected to wire E via wire G, and they intersect at point M.

[0018] One end of the contact K1B is connected to the wire D via a wire, and they intersect at point N. The other end of the contact K1B is connected to the wire F via a wire, and they also intersect at point Y.

[0019] A control method for a magnet-based underwater unmanned vehicle power switch control device, the control method being as follows:

[0020] When the magnet moves from the side where reed switch 2 is located to the side where reed switch 1 is located, reed switch 2 is triggered first, and then reed switch 1 is triggered. After reed switch 1 is triggered, pins 1 and 2 of reed switch 1 are connected. At this time, the relay self-locking circuit board finally receives the instantaneous short circuit signal of reed switch 1, that is, the "switch open" signal. After receiving the "switch open" signal, the coil K1A of relay K1 will conduct. After conduction, the contacts K1B and K1C of relay K1 will close. At this time, coil K1A and the closed contact K1B form a self-locking state. Contact K1C will always be in the closed state. Then the coil K2A ​​of relay K2 will always conduct, and contact K2B will always be closed. At this time, the power supply can continuously supply power to the central control unit of the system, realizing the operation of powering on the underwater unmanned vehicle.

[0021] When the magnet moves from the side where reed switch one is located to the side where reed switch two is located, reed switch one is triggered first, and then reed switch two is triggered. After reed switch two is triggered, pins 1 and 2 of reed switch two are connected. At this time, the relay self-locking circuit board finally receives the instantaneous short circuit signal of reed switch two, that is, the "switch off" signal. After receiving the "switch off" signal, the coil K3A of relay K3 will conduct. After conduction, the normally closed contact K3B of relay K3 will open. After opening, the coil K1A, contact K1B, and contact K1C of relay K1 will all open, thereby causing the coil K2A ​​and contact K2B of relay K2 to open. The power supply to the central control unit of the system is disconnected, realizing the power off operation of the underwater unmanned vehicle.

[0027] Figure 1 This is a schematic diagram of the structure of the present invention;

[0028] Figure 2 This is a schematic diagram of the electrical structure of the present invention; Detailed Implementation

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] Example 1:

[0031] This embodiment provides a magnet-based power switch control device for an underwater unmanned vehicle. The control device is used to control the power supply to power on or off the system's central control unit.

[0032] See appendix Figure 1 The control device includes: a reed switch board and a relay self-locking circuit board encapsulated in a control box, and a magnet located outside the control box; the relay self-locking circuit board is electrically connected to the power supply, the system central control unit and the reed switch board respectively; the magnet is used to control the engagement of the reed switch on the reed switch board;

[0033] The reed switch board includes a board body and two reed switches mounted on the board body. The two reed switches are reed switch one and reed switch two, which are arranged in a straight line on the board body. In this embodiment, as shown... Figure 2 As shown, reed switch one is located on the left side of the board, and reed switch two is located on the right side of the board. Reed switch one controls the power-on command (i.e., the power-on command), and reed switch two controls the power-off command (i.e., the power-off command). When the magnet moves from right to left, reed switch two is triggered first, and then reed switch one is triggered. Therefore, the power-on command triggered later can be executed. Since a short-circuit signal is generated after the reed switches are activated, the short-circuit signal of the power-on command can be sent to the relay self-locking circuit board after the reed switch one is activated later. When the magnet moves from left to right, reed switch one is triggered first, and then reed switch two is triggered. Therefore, the power-off command triggered later can be executed. Since a short-circuit signal is generated after the reed switches are activated, the short-circuit signal of the power-off command can be sent to the relay self-locking circuit board after the reed switch two is activated later.

[0034] The relay self-locking circuit board includes three relays: relay K1, relay K2, and relay K3. When a short-circuit signal for a power-on command is received, the coil of relay K1 is energized and forms a self-lock with the trigger contact, ensuring that the coil of relay K2 remains energized, thereby ensuring the circuit between the power supply and the system central control unit, achieving continuous power supply, i.e., power-on. When a short-circuit signal for a power-off command is received, the coil of relay K3 is energized, triggering the normally closed contact to open, causing the coil of relay K1 to de-energize and release the self-lock, thereby de-energizing the coil of relay K2, and thus disconnecting the circuit between the power supply and the system central control unit, achieving power supply interruption, i.e., power-off.

[0035] Therefore, the control device in this embodiment is installed close to the inner wall of the aircraft. When the power supply is turned on, the magnet can be turned on by moving from right to left above the reed switch plate; the power supply can be turned off by moving from left to right above the reed switch plate.

[0036] See appendix Figure 2 The specific electrical connections between the relay self-locking circuit board, the power supply, the system central control unit, and the reed switch board are as follows:

[0037] The output of pin 1 of the reed switch one is a "switch on" signal, the output of pin 1 of the reed switch two is a "switch off" signal, and the output of pin 2 of the two reed switches is a "switch COM" signal after being connected by wire A. The three signals are respectively connected to the relay self-locking circuit board through wires.

[0038] The relay K1 includes: a relay coil K1A and its contacts K1B and K1C; the relay K2 includes: a relay coil K2A ​​and its contacts K2B; the relay K3 includes: a relay coil K3A and its contacts K3B.

[0039] The positive terminal of the power supply is connected to one end of the contact K2B of the relay K2 via wire B, and the other end of K2B is connected to the positive terminal of the system central control unit; the ground terminal (i.e., the COM interface terminal) of the power supply is connected to the negative terminal of the system central control unit via wire C.

[0040] One end of the coil K1A of relay K1 is connected to pin 1 of reed switch 1 via wire D. The other end of K1A is connected to one end of the normally closed contact K3B of relay K3. The other end of K3B is connected to point X via wire B.

[0041] One end of the coil K3A of relay K3 is connected to pin 1 of reed switch 2, and the other end of K3A is also connected to wire B at point X through wire E;

[0042] One end of the coil K2A ​​of relay K2 is connected to the wire A between pins 2 of the two reed switches via wire F. Wire F and wire C intersect at point Y. The other end of K2A is connected to one end of the contact K1C of relay K1. The other end of K1C is connected to wire E via wire G, and they intersect at point M.

[0043] One end of the contact K1B is connected to the wire D via a wire, and they intersect at point N. The other end of the contact K1B is connected to the wire F via a wire, and they also intersect at point Y.

[0044] Example 2:

[0045] This embodiment, based on Embodiment 1, provides a control method for a magnet-based underwater unmanned vehicle power switch control device. (See attached diagram.) Figure 2 The control method is as follows:

[0046] After the power supply is turned on, when the magnet moves from right to left, it first triggers reed switch two, and then triggers reed switch one. After reed switch one is triggered, pins 1 and 2 of reed switch one are connected. At this time, the relay self-locking circuit board finally receives the instantaneous short circuit signal of reed switch one, that is, the "switch open" signal. After receiving the "switch open" signal, the coil K1A of relay K1 will conduct. After conduction, the contacts K1B and K1C of relay K1 will close. At this time, the coil K1A of relay K1 and the closed contact K1B form a self-locking state. The contact K1C will always be in the closed state. Then the coil K2A ​​of relay K2 will always conduct, and the contact K2B will always be closed. At this time, the power supply can continuously supply power to the central control unit of the system, realizing the operation of powering on the underwater unmanned vehicle.

[0047] When the magnet moves from left to right, it first triggers reed switch one, then triggers reed switch two. After reed switch two is triggered, pins 1 and 2 of reed switch two are connected. At this time, the relay self-locking circuit board finally receives the instantaneous short-circuit signal of reed switch two, namely the "switch off" signal. After receiving the "switch off" signal, the coil K3A of relay K3 will conduct. After conduction, the normally closed contact K3B of relay K3 will open. After opening, the coil K1A, contact K1B, and contact K1C of relay K1 will all open, thereby causing the coil K2A ​​and contact K2B of relay K2 to open. The power supply to the central control unit of the system is disconnected, realizing the power off operation of the underwater unmanned vehicle.

[0048] In summary, the above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
