This invention discloses an integrated sensing, driving, and control system and method for micro-nano robots based on an optical communication protocol. The system includes a control module and connected optical communication, multimodal sensing, driving, and power management modules. The optical communication module uses a preset protocol to achieve bidirectional conversion between optical and electrical signals. The downlink uses PWM encoding and near-infrared light, while the uplink uses Manchester encoding and blue light. The multimodal sensing module integrates multiple sensors, and the sampling parameters are dynamically configured by the control module. The driving module converts control commands into PWM signals to precisely drive micro-actuators. The power management module switches between working and sleep modes according to commands. The control module is responsible for command decoding and system scheduling. This system achieves efficient collaboration of communication, sensing, driving, and control on a single chip, featuring high integration, reliable communication, low latency, and low power consumption. It provides a core technology solution for the application of micro-nano robots in complex environments such as biomedicine and environmental monitoring.

This invention relates to an emergency vehicle system and control method for hydraulic oil failure in a spider crane. The emergency vehicle system includes a spider crane and an emergency vehicle. The emergency vehicle includes a motor and inlet / outlet oil pumps. The motor's power output is connected to the inlet / outlet oil pumps, driving their operation. The inlet and outlet oil pumps are connected to the spider crane's hydraulic system via bidirectional inlet / outlet oil pipes. When a hydraulic oil line failure occurs while the spider crane is operating, the emergency vehicle is connected to the spider crane, and the emergency vehicle's main switch is activated. By controlling the inlet and outlet oil pumps on the emergency vehicle, the spider crane's boom retraction and outrigger folding are achieved. The advantages of this application are: convenient operation, high emergency efficiency, and a quick-connect connection between the emergency vehicle and the spider crane. After activating the main switch, the operator can directly and manually control the retraction of the spider crane from the main body, observe the equipment status in real time, and avoid operational errors. Operation is safe, reliable, and highly adaptable.
