An air volume control method for a working machine cockpit. The method includes: acquiring a real-time environment physical parameter, and acquiring a current air volume parameter; determining real-time heat comfort information on the basis of the real-time environment physical parameter and the current air volume parameter; acquiring target heat comfort information; and determining a target air volume parameter on the basis of the real-time heat comfort information, the target heat comfort information, and the current air volume parameter.

Air volume control method and apparatus for working machine cockpit

An automatic weighting calibration method for an excavator includes: firstly, obtaining a reference data set of the excavator under no-load working state; the reference data set includes a plurality of reference data groups, and each reference data group includes geometry data of the excavator, pressure data of an oil cylinder, dynamic data and no-load weighing data; and then, calibrating a coefficient matrix of the weighing model to realize the automatic weighing calibration for the excavator based on the reference data set. The weighing model is configured to automatically weigh the excavator.

Automatic weighing calibration method, system and excavator

A transmission subsystem has an automatic transfer switch () which includes at least a pair of movable contact members (). The pair of movable contact members includes a first movable contact member () at a first location and a second movable contact member () at a second location. The automatic transfer switch further includes a fixed member (), a controller () configured to select one of the first and second movable contact members, and a permanent magnetic actuator (). The permanent magnetic actuator includes an actuator body, a first driving rod (), and a second driving rod (). The permanent magnet actuator is configured to move the first driving rod in a first direction independently of movement of the second driving rod. The first driving rod is configured to move the first movable contact member, and the second driving rod is configured to move the second movable contact member.

Automatic transfer switch and drive subsystem

An automatic transfer switch system includes a contact subsystem having a plurality of movable contact members, including at least one first movable contact member and at least one second movable contact member at first and second locations, respectively, and at least one fixed contact member. The switch system further includes a permanent magnet operating mechanism that controls opening and closing of the movable contact members relative to the fixed contact member, generates a holding force to maintain a state of the at least one first movable contact member at the first location and a state of the at least one second movable contact member at the second location, and connects to the subsystem via a linkage, and a solenoid permitting movement of the at least one first movable contact member and the at least one second movable contact member at the first and second locations, respectively.

Permanent magnet operating mechanism for use in automatic transfer switch

A transfer switch transfers electric power provided to an electrical load from a first power source to a second power source. The transfer switch includes a coil arrangement that controls movement of a member to open or close a contactor of the first or second power source. The coil arrangement may be used with two voltage levels.
