[0002] In modern industrial automation, security systems and other fields, the control box is the core control device, and its function and performance play a crucial role in the stability and efficiency of the entire system. The existing control boxes have the following main defects: (1) In terms of signal conversion and communication, the existing control boxes cannot directly process various types of signal inputs and require additional conversion devices to perform signal conversion. They also lack support for modern communication protocols such as CAN bus. CAN bus has advantages such as strong real-time performance and strong anti-electromagnetic interference capability, but it is rarely used in existing control boxes, which limits the communication efficiency and stability of the system; (2) They lack modular design and are difficult to configure and expand flexibly according to different application scenarios. In scenarios where multiple devices need to be controlled at the same time or complex control logic needs to be implemented, the existing control boxes often cannot meet the requirements.

Attached Figure Description

[0015] Figure 1 This is a structural schematic diagram of an embodiment of the present utility model. Detailed Implementation

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] like Figure 1The diagram shows a multifunctional control box, comprising a power supply unit, a control unit, a control signal receiving unit, a signal conversion unit, and an external interface unit. The control unit and the signal conversion unit communicate bidirectionally via a CAN bus. The control signal receiving unit and the signal conversion unit communicate bidirectionally via a TTL interface. The power supply unit provides power to the control unit, the control signal receiving unit, and the signal conversion unit. The external interface unit provides a standardized interface for connecting and communicating with external devices such as laser generators, elevators, and pan-tilt units.

[0018] Specifically, the control signal receiving unit includes a remote controller and a remote controller receiver, which are used in pairs. The remote controller receiver communicates bidirectionally with the signal conversion unit via a TTL interface. On one hand, it receives signals from the remote controller, converts the received signals into TTL signals, and then sends them to the signal conversion unit via the TTL interface. The signal conversion unit then converts these signals into CAN signals and outputs them to the CAN bus. On the other hand, it receives TTL signals sent by the signal conversion unit. Preferably, the remote controller is a 10.1-inch screen remote controller, and its display screen can show relevant parameters, such as the distance measured by the rangefinder. The remote controller receiver includes a receiver board, which is equipped with an MCU and receiver chips and interface chips connected to the MCU. Since the circuit structure of the remote controller receiver is already existing technology, it will not be described in detail here.

[0019] In this embodiment, the signal conversion unit includes at least two conversion boards, preferably four. Each conversion board mainly includes an MCU, a CAN transceiver chip, a TTL interface, and a CAN1 interface. The TTL interface is connected to the MCU, and the CAN1 interface is connected to the CAN transceiver chip. The MCU communicates with the CAN bus through the CAN transceiver chip. The main function of the CAN transceiver chip is to convert TTL signals to CAN signals and vice versa. Since the specific circuit structure of the conversion boards is a mature technology, it will not be described in detail in this embodiment. In short, the conversion boards in this embodiment can transmit signals via the CAN bus, convert externally sent TTL signals to CAN signals for transmission on the CAN bus, and convert CAN signals transmitted on the CAN bus back to TTL signals for output to a remote control receiver or external device.

[0020] In this embodiment, the external interface unit includes interfaces for the gimbal, ranging, focusing motor, laser generator, elevator, and power supply. All of these interfaces use GX16 aviation connectors. The gimbal, ranging, and focusing motor interfaces transmit TTL signals from the gimbal, rangefinder, and focusing motor to the signal conversion unit. Specifically, the gimbal, ranging, focusing motor, and remote control receiver interfaces are connected to the TTL interfaces of four conversion boards in the signal conversion unit. These conversion boards convert the TTL signals from the gimbal, rangefinder, focusing motor, and remote control receiver on the robot into CAN signals, which are then output to the CAN bus and sent to the control unit.

[0021] It is understood that the external interface unit of this embodiment can also connect to other external devices, and is not limited to this embodiment.

[0022] In this embodiment, the control unit takes the signal from the signal conversion unit as input. The control unit includes a microprocessor, which can be an STM series chip, DSP, etc. The CAN1 interface of the microprocessor is used to receive the CAN signal sent by the signal conversion unit through the CAN bus. Each digital output interface of the microprocessor is connected to the laser generator interface of the external interface unit via the laser generator power-on relay and the light output signal relay module, and is also connected to the elevator interface of the external interface unit via the motor forward / reverse module. This is used in conjunction with the motor forward / reverse module and the relay module to realize the control signal output of the laser generator, elevator, etc. Specifically, the laser generator power-on relay is a high-power relay, which is connected to the power input terminal of the laser generator via the laser generator interface. By controlling the activation and deactivation of the high-power relay through the microprocessor, the power-on and power-off control of the laser generator can be realized, thereby controlling the start and stop of the laser. The light output signal relay module is preferably an optocoupler relay. The output terminal of the optocoupler relay is connected to the control signal terminal of the laser generator via the laser generator interface. When the optocoupler relay receives the control signal sent by the microprocessor, its internal photosensitive element will conduct, thereby controlling the light output state of the laser generator. The motor forward and reverse rotation module is specifically designed to control the forward and reverse rotation of the motor. It is a mature module, and its structural principles will not be elaborated upon here. Since the lifting platform controls its lifting and lowering through the forward and reverse rotation of the motor, once the motor is connected to the lifting platform interface on the control box, its lifting and lowering can be controlled by a microprocessor.

[0023] In this embodiment, the power supply unit includes a power management module and a step-down module. The power management module has multi-voltage output capabilities of 12V, 24V, and 48V. The step-down module includes a 24V to 9V step-down module and a 24V to 3.3V step-down module to provide power to the required units. The power management module is also connected to the power interface of the external interface unit to provide power to corresponding external devices.

[0024] The working principle of this embodiment is as follows:

[0025] When the rangefinder sends a distance value TTL signal in real time through the ranging interface, the conversion board corresponding to the ranging interface parses the input TTL signal and converts it into a CAN signal, and outputs it to the CAN bus. The CAN bus then transmits the signal to the conversion board corresponding to the remote control receiver. The conversion board converts the CAN signal into a TTL signal and outputs it to the remote control receiver. The remote control receiver then wirelessly transmits the ranging signal to the remote control display screen.

[0026] When the operator issues gimbal and focus control commands based on the distance measurement value displayed on the remote control screen and the actual working conditions, the remote control receiver receives the remote control command signal and simultaneously outputs a signal to the corresponding conversion board of the signal conversion unit via the TTL interface. The conversion board converts the input TTL control command signal into a CAN signal and outputs it to the CAN bus. The CAN bus then transmits the signal to the control unit. The microprocessor in the control unit calculates a specific program based on the received remote control command and outputs the corresponding CAN signal to the CAN bus. The CAN bus then transmits the CAN signal to the corresponding conversion board, which converts the CAN signal into a TTL control signal and outputs it to the gimbal and focus motor, thereby controlling the gimbal and focus motor.

[0027] When the operator issues lifting control, laser light emission, and power-on control commands based on actual working conditions, the remote control receiver receives the remote control command signal and simultaneously outputs a signal to the corresponding conversion board of the remote control receiver via the TTL interface. The conversion board converts the input TTL control command signal into a CAN signal and outputs it to the CAN bus. The CAN bus then transmits the signal to the control unit. The microprocessor in the control unit calculates a specific program based on the received remote control command and outputs signals through the control unit's DO port to the high-power relay, the light emission signal relay module, and the motor forward / reverse module, thereby realizing the control of laser power-on, laser light emission, and the lifting platform.

[0028] In summary, this embodiment, on the one hand, by modularizing the control box, enables it to have clear interfaces, facilitating its integration with different host devices and meeting the laser beam output control requirements of different scenarios and conditions; on the other hand, the signal conversion unit enables efficient communication and data exchange between devices, improving communication stability and system scalability.
