Functional indicating meter for cooperating with sensing element

Abstract

A functional indicating meter for cooperating with sensing elements is disclosed. The meter includes a selecting switch, a signal-controlling module, a signal-receiving module, a signal-judging module, a displaying/alarming module and a panel-indicating module. The sensing signals from several similar sensing elements at different locations are simultaneously inputted into the signal-receiving module. Then, through switching of the selecting switch and the signal-controlling module for selecting the sensing signal wanted to receive, this sensing signal will simultaneously be outputted to the panel-indicating module and the signal-judging module. The panel-indicting module will directly display the value of this sensing signal, and simultaneously the signal-judging module will process a value comparison for abnormal ones. If it reveals abnormal, it can notice the user through the displaying/alarming module. The functional indicating meter can be switched to display the value of each sensing element located everywhere so as to achieve purposes of displaying and alarming.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a functional indicating meter for cooperating with sensing elements, and more particularly to a functional indicating meter that can be switched to display the value of each sensing element located everywhere so as to achieve the purposes of displaying and alarming.

2. Description of the Prior Art

Please refer to FIG. 1 that is a practicing schematic view showing the instrument panel which cooperates with the oil boxes. As shown in FIG. 1, the instrument panel 1 is set on a boat. Because there will be several oil boxes on the boat for long-distance traveling and in order to make the user to understand the oil reserves, all the sensing elements set inside the oil boxes are connected to the instrument panel 1. After the power switch 1 is opened, the power indicator 12 will become to shine. Moreover, the user can refer to an indicating site map 13, located at the upper portion of FIG. 1, and turn a selecting switch 14 to the number which is wanted to know, so that the oil reserve of the indicated oil box can be displayed through a needle meter 15. When the user needs to know the oil reserve of another oil box, the user has to adjust the select switch 14 first and then close the power switch 11 and reopen it again so that the oil reserve of this oil box can be displayed.

The main disadvantages of this conventional instrument panel for cooperating with the oil boxes are:

• • 1. Because the power switch has to be closed first and reopened again in order to successfully switch when the user switches the display of the oil box each time, the operating procedures are too complicated.
  • 2. It has only one single displaying function, and thus it can not warn the user.
  • 3. It has to be inset the needle meter, power switch, power indicator, selecting switch and indicating site map, and thus the volume thereof will become too larger so as to inconvenience the user as installing.
  • 4. It is localized to use in measuring the oil amount of boat, so that if it is used in different field or measuring different sensing sources, it will need to be redesigned.

Thus, it can be seen, the prior art described above still has some defects, is not a good design, however, and is urgently to be improved.

Because of the technical defects of described above, the applicant keeps on carving unflaggingly to develop a functional indicating meter for cooperating with sensing elements through wholehearted experience and research.

SUMMARY OF THE INVENTION

An object of the present invention is to provide a functional indicating meter for cooperating with sensing elements that can be switched to display the value of each sensing element located everywhere so as to achieve the purposes of displaying and alarming.

Another object of the present invention is to provide a functional indicating meter for cooperating with various sensing elements of measuring oil amount, temperature, liquid level and oil pressure etc.

Another further object of the present invention is to provide a functional indicating meter can cooperates with sensing elements and also be used in all kinds of traffic transportations, e.g. airplanes, boats and vehicles etc.

For achieving the purposes described above, the functional indicating meter for cooperating with sensing elements according to the present invention includes a selecting switch, a signal-controlling module, a signal-receiving module, a signal-judging module, a displaying/alarming module and a panel-indicating module. The sensing signals from several similar sensing elements at different locations are simultaneously inputted into the signal-receiving module, and then, through switching of the selecting switch and the signal-controlling module for selecting the sensing signal wanted to receive, this received sensing signal will simultaneously be outputted to the panel-indicating module and the signal-judging module. The panel-indicting module will directly display the value of this received sensing signal, and simultaneously the signal-judging module will process a value comparison for abnormal ones; if it reveals abnormal, it can notice the user through the displaying/alarming module.

  • a signal-controlling module 22 for outputting a control signal to a signal receiving module 23 so as to control a sensing signal outputted by the signal receiving module 23;
  • a signal-receiving module 23 connected to plural similar sensing elements 4 (e.g. oil amount, temperature, liquid level and oil pressure) and receiving the control signal from the signal controlling module 22 for determining which sensing signal is simultaneously outputted to a signal-judging module 24 and a panel-indicating module 26;
  • a signal-judging module 24 for receiving the sensing signal from the signal receiving module 23 and then outputting a status signal to a displaying/alarming module 25 after judging if an abnormal situation reveals;
  • a displaying/alarming module 25 having double-color light emitting diodes (LEDs), whose number are corresponding to that of sensing sources and which change the display thereof depending on a selection of the sensing sources, and if the sensing signal is normal, the double-color LED reveals green color and if the sensing signal is abnormal, the double-color LED reveals red color for alarming the user; and
