This invention discloses an underwater salvage mechanical claw device for fire rescue, comprising an operating lever and an operating frame. A mechanical claw mechanism is connected to the bottom of the operating lever, and a clamping mechanism is connected to the mechanical claw mechanism. The mechanical claw mechanism includes a fixed base and multiple inclined claw plate mounting bases evenly fixed along its outer side. Two single claw plates are symmetrically rotatably connected to the outer end of each claw plate mounting base. A connecting shaft is fixed to the top of the two single claw plates and connected to the clamping mechanism. A cutting blade is provided between the two single claw plates. The top of the cutting blade is rotatably mounted in a rotating groove at the bottom of the claw plate mounting base via a cutting shaft. Both ends of the cutting shaft extend into the claw plate mounting base and are connected to a drive assembly. This device controls the rotation of the cutting blade through the drive assembly, actively cutting obstacles such as fishing nets and aquatic plants entangled on the mechanical claw to avoid jamming. Simultaneously, the inclined double claw plate structure improves the stability and reliability of the gripping action, making it suitable for complex underwater rescue environments.

Embodiments of the present disclosure provide a plasma-enhanced atomic layer deposition apparatus and a method thereof. The apparatus includes a precursor supply device communicating with gas inlet structures of two process chambers and configured to selectively provide a precursor or a purge gas to at least one of the two process chambers, a reaction gas supply device communicating with the gas inlet structures of the two process chambers and configured to selectively provide a reaction gas to at least one of the two process chambers, a radio frequency device connected to the two process chambers and configured to selectively output radio frequency power to at least one of the two process chambers, and a pressure adjustment device communicating with exhaust openings of the two process chambers and configured to independently control chamber pressures of the two process chambers. With the plasma-enhanced atomic layer deposition apparatus and the method thereof of embodiments of the present disclosure, process adjustment manners are increased, and the precursor supply device does not need to be provided for each of the process chambers. Thus, the apparatus costs can be reduced.

The present invention provides a motor control system and a vehicle. The motor control system (1) includes a motor drive module (10), a multi-core processing module (20), and a safety logic module (30). The multi-core processing module (20) includes a main function core (21) and a lockstep monitoring core (22). The main function core (21) is configured to obtain sampling data, and when any one of the sampling data, a running status of the main function core (21), a motor control signal, and a running status of a motor is abnormal, the lockstep monitoring core (22) outputs a safety trigger signal; and the safety logic module (30) is configured to output an instruction for prohibiting execution of the motor control signal to the motor drive module (10) when receiving the safety trigger signal.

The invention belongs to the technical field of flexible direct valve control power supply control, and discloses a flexible direct valve control power supply control system and a control method.The flexible direct valve control power supply control system is characterized in that a plurality of auxiliary function board cards, a power board and a CPU board connected with a far-end control unit are integrated in a valve control case, and the auxiliary function board cards are connected with the power board through a power bus for power supply; the remote control unit is respectively connected with a power supply control unit, and each power supply control unit is connected with the CPU board through a power supply control bus, so that the remote control unit can independently control each power supply control unit to execute power supply operation through the CPU board. According to the system, the power supply control unit is built in and is directly associated with each auxiliary function board card, and after the CPU board receives a remote instruction, each unit is accurately regulated and controlled through the power supply control bus, so that independent management of a specified board card power supply is realized, and control logic can be completed without an external module. By adopting the system, additional configuration of an external module is avoided, the system structure is simplified, the cost is reduced, and refined independent control of a specific board card power supply in the valve control system is realized at the same time.
