摘要:
An arrangement to control equipment over a common network. A serial network transfers commands, and receives data from a plurality of distributed locations. Equipment located at each location executes tasks based on control information received over the network. Each equipment includes a memory which contains data to identify to the serial network, the identity of functions carried out by the equipment. Sensors may be located at some of the locations for generating data for transmission over the network. Each sensor also has a memory which identifies the sensor to the serial network. The plurality of modules connecting each of the equipment and the sensors to the network are configured to read the memory contents to carry out the function identified of the connected equipment or sensor.

A transferable electronic control unit having a non-volatile memory that retains values of learned correction factors for control parameters used in adaptively controlling the operation of a vehicle is disclosed. The electronic control unit receives an identification signal from the vehicle in which it operates. By comparing the value of the received identification signal with a stored value identifying the vehicle operated when learning the values of the correction factors that are stored in non-volatile memory, the electronic control unit determines whether or not it has been transferred between vehicles. When a transfer between vehicles has not occurred, the value of the learned correction factors stored in non-volatile memory are used to begin adaptively controlling vehicle operation. When a transfer between vehicles has occurred, initial or mean values for the correction factors are used to begin adaptively controlling vehicle operation. As a result, the electronic control unit can be transferred between vehicles without causing malfunctions in vehicle operation.

The present invention features a material handling vehicle identification system. The material handling vehicle has a universal system processor for controlling the vehicle speed, acceleration, direction and motion of a plurality of different vehicles. A semiconductor memory device is permanently affixed to the chassis of the vehicle during the manufacturing process. This memory device contains a unique identification tag. The identification tag is remotely disposed from, but operatively connected to the system processor. The identification tag includes data for uniquely identifying the material handling vehicle. The system processor can control the performance of the vehicle as a function of the data in the identification tag, whereby the system processor becomes customized to operate consistant only with the vehicle in which it is installed.

A method of determining an action associated with an apparatus, the apparatus having a disposable component, the method comprising: obtaining (100), by means of a camera (416), data representing a visual code (301, 303) and a visual symbol (302, 304); comparing (120), by means of a processor (414), the visual code represented by said data with a reference code, the reference code indicating an identity of a disposable component of the apparatus, and comparing (130), by means of said processor, the visual symbol represented by said data with a reference symbol, to obtain comparison results; and determining (140) the action in response to the comparison results.
摘要:
An electronic controller 16 for use in controlling vehicle operation comprises first and second memories 22,24, the first containing a plurality of control procedures and data values for controlling the operation of the controller for use with a plurality of different vehicle types, the second containing a plurality of pointers for selecting an appropriate control procedure and appropriate data values for the particular type to which the controller 16 is fitted. Therefore, a single controller 16 can be used with a plurality of different vehicle types. A portable programmer 20 communicates with a host computer 12 of a vehicle assembly line 1 and programs the controllers 16 under control of the host 12. A programming unit 50 is provided at service garages for reprogramming fitted controllers 16 or for programming replacement controllers 16', and can communicate with the host computer 12 for control thereby. The possibility of human error in providing the correct controller 16 for a particular vehicle 10, or in reprogramming a fitted controller 16 or programming a replacement controller 16'is eliminated.

The control unit, especially a motor vehicle control unit, includes a microcomputer (13), a programmable nonvolatile memory (14) connected with or integrated in the microcomputer (13), a serial interface (15) for the microcomputer (13) to which a serial data transmission line (12) can be connected over which data for programming the programmable nonvolatile memory (14) is received in the microcomputer from an external programming unit (11), and a low pass filter connected to a terminal (16) for the serial data transmission line. The low pass filter includes components that produce a signal for enabling the programming of the programmable nonvolatile memory (14) of the external programming unit is connected to the control unit via the serial data transmission line (12). These components preferably include a first resistor (R2) connected between the terminal (16) and a programming-enabling input (19) of the microcomputer (13), a capacitor (C1) connected between the programming-enabling input (19) and ground and a second resistor (R1) connected to ground between the capacitor (C1) and the programming-enabling input.
摘要:
Separate, but related, firmware programs for multiple microprocessor-controlled irrigation controllers that are interrelated in their control of irrigation within an irrigation system are generated off-line at a personal computer. The programs are downloaded into a transportable memory device that holds sixty-four separate programs. The memory device is transported to each irrigation controller and plugged to a digital communication channel. The device automatically identifies itself to the controller, and vice versa. The appropriate program is automatically uploaded from the device to the controller. The controller's old program and its historical irrigation record data is loaded into the device and delivered to the personal computer for validation and analysis. A wireless remote test command assembly, an extension maintenance panel, or a radio-link central module may be alternatively connected to the controller's digital communication channel. The controller is powered by the memory device during the uploading.
摘要:
An NC apparatus in which a single interface is used in common with both an NC operation board and a machine operation board to thereby reduce the apparatus in size and the interfaces in number. A run code generator is provided on the machine operation board, which is removably connected with the interface, for putting the controlling program, which is the high-level language program, into the run state. The interface is a serial interface, preferably an RS-232 type interface.

A rectifier plant control system includes a stored program of a master control to control operation and monitor rectifier plant conditions. The master control is designed to cooperate with optional control systems to accomplish new operations without requiring modifications to the stored program control of the master control. One such optional control system permits accessing the master control from a remote location.The optional control system includes an associated stored program which is utilized by the master control to accomplish the option. This associated stored program is in an address field of the stored program of the master control and is executed by the master control.
