[0001] TEMPERATURE SENSING APPARATUS [0002]

The present invention relates to a temperature sensing apparatus capable of sensing an accurate temperature using a plurality of temperature sensors.

2.

The present invention further includes a temperature deviation setting unit 50 for setting a tolerance of the temperatures sensed by the temperature sensors 1 recognized by the sensor recognition unit 20, And is configured to calculate an average by using only the sensing temperatures of the other temperature sensors (1) while excluding the sensing temperature of the temperature sensor (1) when the tolerance deviates from the set temperature by the deviation setting unit (50).

The present invention further includes a counting unit 60 for counting the temperature sensors 1 removed from the temperature calculating unit 30 and transmitting the counted number to the outside.

The present invention can sense an accurate temperature using a plurality of temperature sensors.

In addition, it is also possible to identify a temperature sensor in which a failure occurs among a plurality of temperature sensors.

Also, the temperature can be checked even if a failure occurs in any one of the plurality of temperature sensors.

1 is a block diagram illustrating a temperature sensing apparatus according to an embodiment of the present invention.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

As shown in FIG. 1, the temperature sensing apparatus of the present invention includes a sensor connection unit 10, a sensor recognition unit 20, a temperature calculation unit 30, and a temperature display unit 40.

First, the temperature sensor 1 can be made of a material of heat resistance, pressure resistance, and temperature resistance so as to withstand a high temperature or a high pressure while measuring the temperature of a fluid or a gas.

The sensor connection unit 10 is connected to a plurality of temperature sensors 1 for sensing the temperature and transmitting the sensing temperature as a signal. The sensor connection part 10 is composed of a connection socket in which connection terminals protruding from the temperature sensors 1 are inserted and electrically connected. That is, the plurality of temperature sensors 1 may be selectively connected to connection sockets which are the sensor connection portions 10.

The sensor recognition unit 20 recognizes the connection status of the temperature sensors 1 connected to the sensor connection unit 10. That is, the sensor recognition unit 20 may be constituted by a sensor or a circuit that recognizes a signal with respect to the temperature transmitted from the temperature sensors 1.

The temperature calculation unit 30 calculates the average temperature by summing the temperatures sensed by the temperature sensors 1 recognized by the sensor recognition unit 20 and dividing the sensed temperatures by the number of the recognized temperature sensors 1. [ The temperature calculation unit 30 may include a programmable IC chip and a PCB on which the electronic components are mounted.

Therefore, the reliability of the measured temperature can be improved by calculating the average of the temperatures transmitted from the temperature sensors 1 by the temperature calculating unit 30. [ That is, the user can confirm the correct temperature.

The temperature calculating unit 30 calculates the average by summing only the temperatures sensed by the recognized temperature sensors 1, so that even if a failure occurs in any one of the temperature sensors 1, The temperature can be used to calculate the average.

The temperature display unit 40 displays the average temperature calculated by the temperature calculation unit 30. [ The temperature display unit 40 may be constituted by a liquid crystal display for displaying the temperature in numerical values.

The temperature calculation unit 30 and the temperature display unit 40 are electrically connected by the signal cable 2. That is, since the temperature calculation unit 30 and the temperature display unit 40 are connected by the single signal cable 2, it is not necessary to install the cables that directly connect the plurality of temperature sensors 1, Can be saved.

Furthermore, the length of the cable can be increased to separate the temperature calculating unit 30 and the temperature display unit 40 from each other. That is, the temperature display unit 40 may be provided at a position that is easy for the user to view.

Further, the present invention further includes a temperature deviation setting unit 50 for setting an allowable deviation of the temperatures sensed by the temperature sensors 1 recognized by the sensor recognition unit 20. That is, the user can set the tolerance of the temperature to 1 to 2 degrees Celsius or 2 to 4 degrees Celsius by using the temperature deviation setting unit 50. [

Accordingly, the temperature calculating unit 30 calculates the average by using only the sensing temperatures of the other temperature sensors 1, excluding the sensing temperature of the temperature sensor 1, when the temperature deviation setting unit 50 deviates from the allowable deviation of the set temperature .

For example, when the temperatures sensed by the temperature sensors 1 are set to 19 degrees Celsius, 21 degrees Celsius, 20 degrees Celsius, 26 degrees Celsius, with the tolerance set at 1 to 2 degrees through the temperature deviation setting unit 50 , And the temperature calculating unit 30 divides the temperature by the number of the temperature sensors 1 except for the temperature sensor 1 which senses 26 degrees after adding the temperature of 19 degrees Celsius, 21 degrees Celsius and 20 degrees Celsius except for 26 degrees Celsius, . That is, the sensing ability may deteriorate due to the phenomenon of deterioration due to long-term use of the temperature sensor 1 in a state where the temperature sensor 1 is not electrically short-circuited. Accordingly, the reliability of the temperature sensing can be improved by calculating the average temperature by using the sensing temperatures of the temperature sensors 1 judged as normally operating.

Furthermore, the present invention further includes a counting unit 60 for counting the temperature sensors 1 excluded from the temperature calculating unit 30 and transmitting the counted number to the outside. Therefore, the counted number transmitted from the counting unit 60 can be received by the temperature display unit 40 and displayed as a numerical value. At this time, the temperature sensors (1) recognized by the sensor recognition unit (20) should be indicated by letters, numerals or symbols in the temperature display unit (40). That is, the counting number is displayed as a numerical value on one side of the character of the temperature sensor 1 displayed on the temperature display section 40. In this manner, the number of counts displayed can be visually checked by the user, and the replacement time of the temperature sensor 1 can be grasped.

The present invention also includes a fault detection unit 70 for detecting a temperature sensor 1 that does not transmit a signal to the sensing temperature among the temperature sensors 1 recognized by the sensor recognition unit 20, And an alarm unit (80) for alarming the detection state of the battery (70).

The failure detection unit 70 may be constituted by a sensor or a circuit that detects the temperature sensor 1 that does not transmit a signal with respect to the sensing temperature. The alarm unit 80 may comprise an alarm for outputting sound or a lamp for emitting light.

Accordingly, the user can confirm the failure of the temperature sensor 1 by sound or naked eye as the alarm unit 80 alerts by the detection of the failure detection unit 70.

As described above, the present invention is a very useful invention that can be widely used by being applied to devices in which a fuel such as a boiler is burnt and continuously generated temperature.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is to be understood, therefore, that the embodiments described above are to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than the foregoing description, and the meaning and scope of the claims and their equivalents It is to be understood that all changes and modifications that come within the meaning and range of equivalency of the claims are to be embraced within their scope.
