[0002] The working state of the UAV launch and control mechanism directly affects the overall performance of the UAV system, and the UAV launch and control mechanism needs to be tested. The existing UAV launch and control mechanism detection device includes a control panel and a digital tube, which can realize the real-time display of the status of the UAV launch and control mechanism, such as the rotation speed, but the input setting of the digital tube is complicated, and the parameters need to be set or monitored by buttons, and the switching between the first layer parameters and the second layer parameters is inconvenient to operate; in addition, the existing detection device does not have its own battery and relies on the power supply of the whole vehicle during operation. If the whole vehicle is powered off, the detection device cannot be used. Summary of the invention

[0003] During the inspection of the unmanned aerial vehicle's control mechanism, the applicant discovered that if the entire vehicle loses power in an emergency, the motor of the unmanned aerial vehicle's control mechanism will automatically brake. However, in order to disassemble the motor shaft of the control mechanism, the motor needs to be released. The existing detection device does not have a brake control function, which makes it impossible to easily control the motor to release the brake through the detection device in an emergency. In addition, if an event occurs during the detection process that requires the motor to brake, it cannot be achieved through the detection device.

[0004] The purpose of the present invention is to solve the problems of the prior art unmanned aerial vehicle control mechanism detection device, such as complex input settings, no built-in battery, and inability to control motor brake and release, and to provide an unmanned aerial vehicle control mechanism detection device.

[0009] The battery is fixed in the housing and is used to provide backup power for the control panel and to provide power for the brake switch;

[0010] The multiple connectors are installed on the surface of the shell, including a communication connector and a brake control connector. The communication connector is used to electrically connect the driver of the motor in the unmanned aerial vehicle control mechanism to the control board to provide power to the control board and obtain the state parameters of the unmanned aerial vehicle control mechanism. The brake control connector is used to electrically connect the motor of the unmanned aerial vehicle control mechanism to the control board so that the control board outputs brake switch power to control the braking and releasing of the motor.

DETAILED DESCRIPTION

[0025] The present invention will be described in detail below with reference to the accompanying drawings by means of exemplary embodiments of the present invention. It should be noted that the following detailed description of the present invention is only for the purpose of illustration, and is not intended to limit the present invention.

[0026] The present invention provides a detection device for an unmanned aerial vehicle launch control mechanism, which is used for detecting an unmanned aerial vehicle launch control mechanism, such as a missile launch control mechanism, and performing brake and release control on a motor of the mechanism.

[0027] Reference Figure 1 and Figure 2As an exemplary embodiment of the present invention, the detection device for the control mechanism of an unmanned aerial vehicle comprises a housing 1, a control panel 2, a human-machine interface 3, a battery 4 and a plurality of connectors. The housing 1 is used to provide support for the detection device. The control panel 2 is used to control the operation of the detection device. The human-machine interface 3 can display the state parameters of the control mechanism of the unmanned aerial vehicle and input the control instructions of the control mechanism by the user.

[0028] The housing 1 may include a housing body 11 and a cover 12 . The housing body 11 is in a box shape with one side open. The cover 12 may be mounted on the housing body 11 to close the housing body 11 .

[0029] The control panel 2 is installed in the housing 1 and can be limited by the mounting plate 21. It is mainly responsible for the operation and control of the entire system. The control panel 2 can communicate with the UAV control mechanism through the 485 communication protocol and the 422 communication protocol, process the information received from the UAV control mechanism, and send the status data and alarm information to the human-computer interaction interface 3 for display.

[0030] The human-machine interaction interface 3 is installed on the surface of the housing 1, especially on the cover 12 of the housing 1, and is used to display the state parameters of the unmanned aerial vehicle control mechanism obtained and processed by the control board 2, and receive control instructions and transmit the received control instructions to the control board 2, and the control board 2 sends the control information to the unmanned aerial vehicle control mechanism to perform corresponding actions. The control instructions may include parameter settings, unmanned aerial vehicle control mechanism debugging, unmanned aerial vehicle control mechanism zero position calibration, and manual brake and release. When inputting to the human-machine interaction interface, only the interface needs to be operated, and the input setting is simple and the operation is convenient.

[0031] To facilitate the connection and input settings, in some embodiments, the human-computer interaction interface 3 includes a liquid crystal display terminal 31 and a key module 32. The liquid crystal display terminal 31 is used to display the state parameters of the unmanned aerial vehicle control mechanism obtained by the control board 2, and can display the state information, alarm status and parameter setting values ​​of the unmanned aerial vehicle control mechanism. The liquid crystal display terminal 31 communicates with the control board 2 through the TTL serial port. The key module 32 is used to receive control instructions and transmit the received instructions to the control board 2. The control board 2 identifies the operation information of the key module through the I / O port connected to the key module 32, and sends the data set by the operator to the unmanned aerial vehicle control mechanism. The key module may include the following seven buttons: "Up", "Down", "Left", "Right", "Confirm", "Set" and "Brake", and its functions are as follows:

[0032] Setting: Self-reset button. Repeated operation of this button can turn on and off the parameter setting function in turn.

[0033] Up: Self-reset button. In parameter setting mode, after operation, you can select the item to be set upwards;

[0034] Down: Self-reset button. In parameter setting mode, after operation, you can select the item to be set downwards;

[0035] Left: Self-reset button. In parameter setting mode, after operation, you can select the item to be set on the left;

[0036] Right: Self-reset button. In parameter setting mode, after operation, you can select the item to be set to the right;

[0037] Confirm: Self-reset button. In parameter setting mode, after operation, the items and data to be set can be confirmed;

[0038] Brake: Press this button when you need to manually release / close the motor brake. Press this button repeatedly to release and close the motor brake in turn.

[0039] The battery 4 is fixed in the housing 1, and is used to provide backup power for the control board 2 and to provide power for the brake switch. In order to stably and reliably install the battery 4 in the housing 1, the detection device preferably includes a battery fixing frame 41, which is connected in the housing 1 and is used to fix the battery 4 to the housing 1. The battery 4 can be firmly clamped in the battery fixing frame 41.

[0040] The battery can be a DC24V battery. The DC24V battery can be used in conjunction with a battery charger. The battery has a nominal voltage of 22.2V, a wide voltage operating range of 16.5V to 25.2V, and a nominal capacity of 2600mAh. To this end, the detection device also includes a charging connector 8 for connecting the battery charger to charge the battery 4.

[0041] The battery 4 may also be provided with a protection circuit having overcharge protection function, over-discharge protection function, over-current protection function and short-circuit protection function.

[0042] Multiple connectors of the detection device are mounted on the surface of the housing 1, especially on the side surfaces of the housing body 11, and these connectors include a communication connector 5 and a brake control connector 6. Both connectors 5 and 6 include a connector socket assembly and a connector plug cable assembly.

[0043] The communication connector 5 is used to electrically connect the driver of the motor in the UAV control mechanism to the control board 2, so as to provide power to the control board 2 and obtain the state parameters of the UAV control mechanism. The UAV control mechanism provides DC5V power to the control board 2 through the communication connector 5, and the driver performs 485 communication and 422 communication with the control board 2 through the communication connector 5. When the whole vehicle is powered off, the driver cannot power the control board 2 through the communication connector 5. At this time, the battery 4 can power the control board, and the detection device can still work, so that the motor can be controlled by the detection device. If the battery 4 does not exist, the detection device cannot continue to work when the whole vehicle is powered off, and the detection device cannot be used to brake / unbrake the motor.

[0044] The brake control connector 6 is used to electrically connect the motor of the unmanned aerial vehicle control mechanism to the control board 2, so that the control board 2 outputs the brake switch power to control the motor's brake and release. The control board 2 controls the motor's release / closing of the brake by whether the brake control connector 6 outputs DC24V electricity. For example, when the whole vehicle is powered off and the motor is braked in an emergency, when the motor needs to be released from the brake, the brake release command can be input through the human-machine interface 3, and the control board 2 can use the battery 4 to output the DC24V brake switch power to the motor through the brake control connector 6, thereby simply releasing the motor from the brake. On the other hand, when the motor is in the release state and needs to be adjusted to the brake state, the brake command can be input through the human-machine interface 3, and the control board 2 can cut off the DC24V brake switch power supplied to the motor, thereby causing the motor to brake.

[0045] In order to facilitate changing the software version and debugging the device, the detection device of the present invention may also include a debugging connector 7 as a programming and debugging interface for updating the software of the control board 2 through a programming and debugging tool.

[0046] The detection device may have the following functions: system status display and real-time display function. By shielding the corresponding alarm lights, the power supply, enable and other states of the unmanned aerial vehicle control mechanism can be displayed, and the motor resolver fault alarm, overload alarm, motor overheat alarm, bus overvoltage alarm, bus undervoltage alarm, position loop resolver alarm, control power overvoltage alarm, control power undervoltage alarm, etc. are indicated by lights; real-time display of system parameters, such as software version number, hardware version number, bus voltage, current, speed set value, speed actual value, current position codeword and other states; JOG function, which can control the motor to jog at a specified speed; position loop motion function, which can drive the unmanned aerial vehicle bracket to run to a specified angle; zero position calibration function, which can calibrate the zero position of the unmanned aerial vehicle bracket position encoder; brake control function, which can manually release / close the motor brake; its own 24V over- and under-voltage protection, 5V over- and under-voltage protection function, and communication fault self-detection function.

[0047] The process of the detection device of the present invention detecting the unmanned aerial vehicle control mechanism is as follows: the detection device sends a query command to the unmanned aerial vehicle control mechanism at a fixed period, and the device body receives a response frame information from the unmanned aerial vehicle control mechanism every time it sends a frame of data. The device body judges the response frame data according to the communication protocol, thereby obtaining the state information, fault information and various parameter values ​​of the unmanned aerial vehicle control mechanism, and displays the obtained state information, fault information and parameter values ​​in real time on the human-computer interaction interface; the detection device sets various parameter values ​​and action instructions by identifying the user's operation on the human-computer interaction interface, and sends the various parameter values ​​and action instructions set by the user to the unmanned aerial vehicle control mechanism. In this way, the unmanned aerial vehicle control mechanism is debugged and judged whether it works normally.

[0048] Taking "control power overvoltage alarm" as an example, the device body sends query instructions to the UAV control mechanism at a fixed cycle. Each time the device body sends a frame of data, it will receive a response frame information from the UAV control mechanism. The device body determines the response frame data according to the communication protocol. If the device body recognizes that there is "control power overvoltage alarm" information in the response frame information, the human-computer interaction interface will immediately display the "control power overvoltage alarm" information, prompting the user that the UAV control mechanism is faulty at this time, and the fault information is control power overvoltage. After that, the device body continues to send query instructions to the UAV control mechanism at a fixed cycle. If it recognizes that the "control power overvoltage alarm" information is lifted, the device body display terminal will no longer display the "control power overvoltage alarm" information.

[0049] Therefore, as described above, the unmanned aerial vehicle control mechanism detection device of the present invention is provided with a human-machine interaction interface and a battery, and the battery can provide backup power for the control panel. When the whole vehicle is powered off, the battery can power the control panel, and the detection device can still work; in addition to displaying the status parameters, the human-machine interaction interface can also input the control instructions for the unmanned aerial vehicle control mechanism, and when inputting, it is only necessary to operate on the interface, and the input setting is simple and the operation is convenient; when the motor is braked and the motor needs to be released, the brake release instruction can be input through the human-machine interaction interface, and the control panel can use the battery to output the brake switch power to the motor to control the motor to release the brake. Similarly, the motor can also be adjusted from the brake release state to the brake state, which expands the use function of the detection device and enhances the practicality of the device. In addition, in the detection device of the present invention, all components are installed on the shell, which is easy to carry and use.

[0050] Finally, it should be noted that the features mentioned and / or shown in the above description of the exemplary embodiments of the present invention may be combined in the same or similar manner into one or more other embodiments, combined with the features in other embodiments or substituted for the corresponding features in other implementations. The technical solutions obtained by these combinations or substitutions shall also be deemed to be included in the protection scope of the present invention.
