Vehicle dynamic display device

Abstract

Abstract PURPOSE:To execute polling at an extremely high speed by executing the polling basing on whether a data stored in a main memory means in a base station is new or not, and whether a data quantity exceeds a prescribed quantity or not. CONSTITUTION:While ''Is there a data display request?'' from a keyboard 2 is ''NO'', a device is held as it is. When ''Is there a data display request?'' becomes ''YES'', a command is outputted from the keyboard 2, a data stored in a main memory means 10, namely, ''Is there the car concerned in an object area?'' is decided. A data from a comparing means 6 is always counted by a counter means 12, and also stored in a temporary storage means 13, therefore, when a collected data in the counter means 12 does not exist, ''NO'' is obtained, and the operation is shifted to a ransmitting operation of a polling signal by the limiter means 14 and the command from the keyboard 2. When a data in the counter means 12 exists, ''YES'' is obtained, and subsequently, ''Is its data new or not?'' is decided.
