Abstract

PURPOSE:To provide a thermometer which informs that the temperature exceeds a preset temperature range by a buzzer or the like. CONSTITUTION:A preset temperature range is stored in a memory means 13 through an input/output control means 16 by an input means 12. a At the time of measuring the temperature, the temperature measured by a thermistor 11 as a temperature measuring means is stored in the memory means 13 through the input/output control means 16 and displayed by a display means 14. After that, the measured temperature is compared with a preset temperature. If it exceeds a high temperature limit or a low temperature limit, a warning is generated by an informing means 15 such as a buzzer or the like. The unit is stored in a heat insulating means 17 for ensuring the temperature measuring operation of the unit itself.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thermometer, and more particularly to one having means for notifying when a set range is exceeded.

0002

[Prior Art] Conventional thermometers simply display the temperature value of the object to be measured, and the measurer must judge whether the displayed temperature is within a desired range. .

0003

[Problems to be Solved by the Invention] However, since conventional thermometers display values, there is a problem in that the temperature of the object to be measured can only be known by looking at the values. Furthermore, many modern industrial devices are easily affected by temperature, and managing the temperature of each device one by one would be very difficult and would be inconvenient in practice.

SUMMARY OF THE INVENTION An object of the present invention is to solve these conventional problems and to provide a thermometer that allows the temperature state to be checked even from a distance and allows easy temperature control.

[0005]

[Means for Solving the Problems] In order to achieve this object, the thermometer of the present invention includes a temperature measuring means for measuring temperature, and a means for inputting numerical values of a set temperature range and switching display states. An input means, a memory means for storing set or measured temperature values, a display means for displaying the input status or value or the measured temperature, and their input/output The thermometer has an input/output control means for management, a notification means for issuing an alarm when the temperature exceeds a preset temperature range, and an insulation means for ensuring the temperature measurement operation of the thermometer itself. There is.

[0006]

[Operation] In this configuration, if the temperature of the object to be measured falls outside the set temperature range, a notification such as a buzzer will be issued.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A thermometer according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of this thermometer, 11 is a thermistor which is a temperature measuring means, 12 is an input means for inputting a numerical value of a set temperature range and switching the display state, 13 is a setting, or a memory means for storing measured temperature values; 14 is an LCD for displaying the input status and values or the temperature being measured;
15 is a piezoelectric buzzer for sounding an alarm (notification means), 16 is input/output control means for managing these inputs and outputs, and 17 is for guaranteeing the temperature of this thermometer itself. 18 is a power supply means for driving this thermometer.

Regarding the thermometer consisting of the above components,
The relationship and operation of each component will be explained with reference to the flowchart in FIG.

First, in step 1, it is assumed that power has already been supplied from 11, and the set temperatures of the high temperature limit and low temperature limit are the upper and lower limits of temperature guarantee in the initial state, and are already stored in the memory means 13. shall be taken as a thing. In step 2, if the information obtained from the input means 12 is temperature setting, the process proceeds to step 9; otherwise, the process proceeds to step 3.

First, in step 3, the thermistor 11
Get temperature information from. In step 4, the temperature information obtained in step 3 is transferred to the memory means 1 via the input/output means 16.
Save to 3. In step 5, the temperature information registered in step 4 is displayed on the LCD display means 14 via the input/output control means 16. In step 6, the measured temperature information stored in the memory means 13 is compared with the set low temperature limit, and if the measured value≦the set low temperature limit, the process goes to step 8, otherwise the process goes to step 7. In step 7, the measured temperature information stored in the memory means 13 is compared with the set high temperature limit, and if the measured value≧the set high temperature limit, the process goes to step 8; otherwise, the process returns to step 2. In step 8, piezoelectric buzzer 1
Ring 5 and return to step 2.

Next, when step 2 to step 9 is reached for temperature setting, it is determined whether the information obtained from the input means 12 is for setting a high temperature limit or a low temperature limit. If the high temperature limit is to be set in step 9, the high temperature limit is input from the input means 12 in step 10, and if the low temperature limit is to be set, the low temperature limit is set from the input means 12 in step 11. After the setting in step 10 or step 11, in step 12, the information in step 10 and step 11 is transferred to the memory 1 through the input/output control means 16.
Registered to 3. In step 13, the temperature information registered in step 12 is sent to the LC via the input/output control means 16.
D is displayed on the display means 14, and the process returns to step 2.

As described above, according to the above embodiment, when the measured temperature obtained from the thermistor 11, which is the temperature measuring means, exceeds the temperature range set from the input means 12, the piezoelectric buzzer 15 sounds. Temperature status can be checked even from a distance, making temperature management easier.

[0014] This embodiment can be made compact and can be placed and retrieved at any time where temperature control is required, like a pocket calculator, for example.

Although not described in the above embodiment, if an input is received from the input means 12 while the piezoelectric buzzer 15 is sounding, the buzzer automatically stops, thereby reducing power consumption. In addition to suppressing the sound, the sound can be stopped after confirmation by the operator.

Although a piezoelectric buzzer is used as an example of the notification means, other means for emitting sound may be used, or notification may be made by lighting or blinking a lamp or the like.

[0017]

[Effects of the Invention] As described above, the thermometer of the present invention uses a notification means such as a piezoelectric buzzer to sound when the measured temperature exceeds a set temperature limit, so that the temperature can be checked even from a distance. This has a great practical effect of making temperature control easier.
