摘要:
A control device includes a storage device for prestoring rendering command data, a central processing device, and a rendering processing device. The rendering command data is data for generating a rendering command executed in order to generate display data indicating a display image to be displayed on a display device. The central processing device refers to a screen management table when a predetermined rendering condition is satisfied, and specifies and outputs rendering command specifying data corresponding to the satisfied rendering condition. The rendering processing device acquires the rendering command data specified by the outputted rendering command specifying data from storage device, generates display data based on the acquired rendering command data, and outputs the display data to the display device.

An application program changes a property value of a graphic object arranged in an object database. An object manager reads out the property value from the object database and then issues a drawing command. A graphics engine executes the drawing command to configure a memory image of the graphic object on a VRAM to display the image on a liquid crystal display via an LCDC.

A sampler samples a receive signal received via a dedicated communication line. A data transfer rate adjuster measures a data transfer rate based on a number of start bit samples contained in the receive signal. A bit determiner makes a bit determination regarding the receive signal at the data transfer rate measured by the data transfer rate adjuster, to thereby acquire serial data contained in the receive signal. A transmitter sends, via the dedicated communication line, a transmit signal containing serial data sent by an MPU. An MPU communicator outputs to the transmitter the serial data sent by the MPU, and outputs to the MPU the serial data acquired by the bit determiner. The data transfer rate adjuster adjusts, when the transmitter sends the transmit signal multiple times at different data transfer rates, the data transfer rate based on the receive status of respective response signals thereto.

A switcher transmits, to an extractor/signal determiner, a converted current signal generated by a current-voltage converter when a converted current signal determiner determines that the converted current signal is generated by transmission of a current signal over a communication line, in the meantime, performs a switch-over so as not to transmit, to the extractor/signal determiner, a converted voltage signal generated by a voltage sensor. In addition, the switcher transmits, to the extractor/signal determiner, the converted voltage signal when a converted voltage signal determiner determines that the converted voltage signal is generated by transmission of a voltage signal over a communication line, in the meantime, performs a switch-over so as not to transmit, to the extractor/signal determiner, the converted current signal generated by the current-voltage converter.

A state display device capable of reducing a processing load applied to a microcomputer by performing part of a GUI process by hardware and a display method of the state display device are obtained. A rendering processing device starts a process in response to a rendering request stored in a rendering request region when a starting command is stored in a start/end instruction register. When a rendering request specified by an instruction address is a rendering termination request, the rendering processing means terminates the process performed in response to the rendering request, stores a termination factor in an interruption factor register, and issues an interruption to a central processing device.

摘要:
A voltage/current verifier computes, for each phase, a phase difference between phase voltage and phase current from the phase of phase voltage and the phase of phase current computed for each phase by a phase acquirer, and determines conformity if all of the computed phase differences are within a preset range. A current/current verifier computes phase differences between phase currents from the phase of phase current computed for each phase by the phase acquirer, and determines conformity if all of the computed phase differences are less than 180°. A reporting device reports that a current transformer is incorrectly placed on a power line unless both the voltage/current verifier and the current/current verifier do not determine conformity.
