Inspection system for a group of tanks
First Claim
Patent Images
1. An inspection system for a plurality of liquid containing tanks comprising:
- a generator means at each of said tanks, each generator means including measuring means for measuring the temperature and the level of the liquid in a tank;
converter means coupled to said measuring means for converting output signals from said measuring means into parallel digital signals;
parallel-series conversion means coupled to said converter means for converting parallel digital signals from said converter means into series digital data signals and for adding a mark signal to said series digital data signals;
clock signal generating means coupled to said parallel-series conversion means for generating a clock signal to control the output timing of the series digital data signals formed by said parallel-series conversion means; and
means for transmitting the series digital data signals produced by said parallel-series conversion means, said series digital data signals representing the level and temperature of the liquid in the respective tank; and
a receiver means for receiving said signals transmitted by said generator means, said receiver means including selection means for selecting signals generated by a selected one of said generator means;
pulse discriminating means coupled to said selection means for detecting a mark signal from the selected received signals;
a further clock signal generating means for providing a clock signal having substantially the same frequency as that of said clock signal generated in said selected generator means after detection of said mark signal to provide synchronization between the receiver means and the received signals;
series-parallel conversion means coupled to said further clock signal generating means of said receiver means for converting received series data into parallel data; and
indicator means coupled to said series-parallel conversion means for displaying outputs of said series-parallel conversion means which correspond to the liquid temperature and liquid level in the tank associated with the selected generator means.

Abstract
An inspection system for a group of tanks, comprises a generator at each tank in which the temperature and the level of the liquid contained in each tank are converted into series data digital signals and start mark signals; and the series data signals are synchronized with clock signals and are transmitted to a receiver. The receiver includes a selector and pulse discriminator for selecting and detecting the start mark signals from a selected generator out of the received series data signals in the receiver. Clock signals are synchronized with the clock signals of the generator side by using the start mark signals; the received and selected series data signals are converted into parallel data signals and the content of the converted parallel data signals is displayed by an indicator to indicate the temperature and level of the liquid in the selected tank.
