This utility model discloses a data processing board for trackside equipment, belonging to the technical field of subway trackside equipment. It includes a data processing module, a soft-start output module, a power-down voltage monitoring module, an RTC real-time clock module with a first energy storage capacitor, a power supply module with a second energy storage capacitor, and a data interface module. The data processing module is electrically connected to the other modules. The power supply module provides the operating voltage to the board, and its second energy storage capacitor temporarily supplies power to the data processing module during brief external power outages to record the voltage status data at the moment of power failure. The first energy storage capacitor of the RTC real-time clock module maintains clock operation for a preset duration after power failure. This utility model solves the problems of easy data loss and clock failure during power failures in traditional boards. It features high structural integration, stable operation, and accurate recording of power-down fault conditions, meeting the data continuity requirements of subway trackside equipment.

The utility model provides a pitching structure and a toy. The pitching structure comprises a shell, a pitching assembly, a driving assembly, a transmission assembly and a limiting assembly. When the driving assembly drives the output end of the transmission assembly to rotate in the first direction, the pull rope can be tensioned. When the pull rope is tensioned, the reset piece is compressed, so that the pitching assembly rotates towards the second direction and is in a buckled state; when the driving assembly drives the transmission assembly to rotate in the direction opposite to the first direction, the transmission assembly releases the pull rope, the reset piece resets, and the pitching assembly can be rotationally opened from the buckled state in the direction opposite to the second direction, so that the pitching assembly is in the opened state. According to the pitching structure, the driving assembly, the transmission assembly and the limiting assembly are ingeniously matched with one another, the rocker arm can be buckled, the opening state of the rocker arm can be kept and switched, and when a toy shell is installed on the pitching assembly of the pitching structure, the interestingness of a toy is improved.

This invention discloses a multi-rotor, spatially coordinated, multi-pose unmanned aerial vehicle (UAV) structure. The structure comprises at least two sets of rotor units, each rotatably connected to a payload platform via a rotary joint to achieve spatial pose transformation of the payload platform. The payload platform also includes an attitude detection unit, a coordination control unit, and an interface unit. The attitude detection unit, interface unit, and the drive motors of the rotor units are connected to the coordination control unit. The attitude detection unit detects the attitude of the payload platform. The coordination control unit, based on data input from the attitude detection unit and interface unit, controls the drive motors of the rotor units to achieve coordinated operation among the multiple sets of rotor units, thereby completing or maintaining the pose transformation of the payload platform. This invention enables the payload platform to change its spatial orientation in multiple directions, allowing for convenient adjustment of the equipment mounted on the payload platform to operate in the required posture for better aerial operations.

The invention discloses a cooperative garbage can cover opening and closing control system and method for an unmanned sweeper. The system comprises a first photoelectric sensor and a second photoelectric sensor which are horizontally arranged in a spaced mode. The relay group and the electric actuator are electrically connected with the first photoelectric sensor and the second photoelectric sensor; the relay set is configured to execute the following steps: the first photoelectric sensor and the second photoelectric sensor are triggered simultaneously to open the garbage can cover; if neither the first photoelectric sensor nor the second photoelectric sensor is triggered, the garbage can cover is closed; only the first photoelectric sensor or the second photoelectric sensor is triggered, locking of the electric actuator is executed, and the garbage can cover is kept at the current opening degree; the system is specially designed for the cooperative garbage can of the unmanned sweeper, a pure hardware logic control system composed of a sensor and a relay is adopted, a microprocessor and a complex algorithm are not needed, three-state control logic is constructed, and the system is suitable for the operation processes of repeated forward and backward movement, fine adjustment, alignment and the like of the unmanned sweeper.
