摘要： Disclosed are a concrete distributing device and a control method, a control system and an electrical control system for composite motion of a boom thereof. The control method comprises the steps as follows: calculating the flow of a boom pump when an operating handle sends a command; according to the command sent by the operating handle, calculating theoretical demand flow of all actuating mechanisms of the boom and theoretical control signals of all electronic proportional control valves; comparing the total theoretical demand flow of the actuating mechanisms with the flow of the boom pump; providing the theoretical control signals to all the electronic pro portional control valves when the flow of the boom pump is greater than or equal to the total theoretical demand flow of the actuating mechanisms, otherwise, providing actual control signals smaller than the theoretical control signals to all the electronic proportional control valves and reducing the movement speeds of all the actuating mechanisms proportionally. In this way, when undersaturation of system occurs to the composite motion of the boom, the movement speeds of all the actuating mechanisms are reduced proportionally independent of the load difference of the actuating mechanisms, thereby ensuring that the boom can move in a motion track expected by an operator.

摘要： A latching valve, useable in a multiplexed fluid control system, is switchable between two positions to control working output fluid flow to a corresponding actuator. The valve is latched by deriving a holding force from the working output flow. The latching valve may reside in one of the channels of the multiplexed fluid control system and eliminates the required modulations to hold position and reduces system wear of modulating and multiplexing components. The latching valve includes a working output port coupled with an associated actuator and a control chamber connected to a 3-way multiplexing valve to receive fluid signals. To provide a latching force, the valve includes bleed conduit that bleeds a controlled amount of fluid between the working output port and the control chamber to maintain the pressure in the control chamber. The last position of the latching valve is held until the next selective fluid signal from the modulating valve and multiplexer is received.

摘要： A control module adapted for use as either a master controller or device controller in a distributed electrohydraulic system includes a microprocessor-based control circuit with digital memory having stored therein a plurality of programs for controlling operation of the controller in a variety of applications. A plurality of analog inputs provide a mechanism for connecting sensor signals or the like to input ports of the control microprocessor. A plurality of electrohydraulic valve driver circuits have inputs for receiving valve control signals from the control microprocessor, and outputs for selective connection to electrohydraulic valves coupled to the devices to be controlled. Serial communication circuitry is coupled to the control microprocessor and adapted for connection to a high-speed electrohydraulic bus. A plurality of control routines are prestored in a memory library, as is an executive routine that is employed for operating the microprocessor whether the controller is configured as a master or a device controller. To configure a controller for operation as a master controller or device controller, and to configure the controller for operation in association with a specific type of electrohydraulic device or devices, a selectively programmable and reprogrammable subroutine list coordinates the executive routine with the various control subroutines in the control library for interrelating the analog input signals, the serial communication signals and/or the valve control output signals so as to dedicate operation of the controller as a master controller or as a device controller for a specific type of electrohydraulic device.

摘要： A multiplexed hydraulic control system which avoids the use of a rotary multiplexer and thereby allows for random selection of the multiplexed outlet ports and variable dwell times for the respective ports. A single hydraulic input is multiplexed among a plurality of hydraulic outputs. A control system provides two types of signals: (1) modulation signals selected from a plurality of multiplexed input signals for producing a modulating hydraulic flow, and (2) selector signals for operating on the multiplexer means to route the modulated signal to the appropriately selected channel.

摘要： An apparatus providing for the generation, control and application of power to a cyclic functioning machine, using fluids under pressure to transmit and control energy by means of a rotary, segmented cam wheel. The cam wheel provides a plurality of interchangeable segments formed into a rim portion with axially spaced complementary counteracting cam faces formed about opposite rim ends. An individual cam follower, carried on a piston rod of a related hydraulic cylinder, coacts with each of the cam faces to accurately regulate the flow of hydraulic fluid to and from a working cylinder of a machine to provide timed and synchronized machine functions through the control movement of the working cylinder. The contoured configuration of the cam faces are arranged to provide for a desired acceleration and retardation of machine motions. Further, variable speed drive means, employed to drive the cam wheel, provides a timing adjustment between machine cycles.

摘要： A dual mode control system for a work vehicle includes a hydraulic system configured to drive a loader assembly and a dozer assembly coupled to the work vehicle. The hydraulic system includes a fluid delivery system comprising a plurality of flow paths fluidly coupled to a hydraulic pump. The hydraulic system includes a valve assembly configured to regulate diversion of fluid into a first and a second hydraulic cylinders coupled to the fluid delivery system to adjust the loader assembly, or into a third cylinder coupled to the fluid delivery system to adjust the dozer assembly. The dual mode control system also includes a controller operably coupled to the valve assembly, and one or more user interfaces coupled to the controller to enable an operator to provide inputs to cause the controller to adjust the valve assembly, and to thereby adjust the loader assembly or the dozer assembly.
