Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner control wireless sensor for setting conditions for an air conditioner in a building and controlling the air conditioner based on measured data such as temperature and humidity.

[0002]

2. Description of the Related Art When controlling the air conditioning of a building, sensors for temperature, humidity, air volume, etc. are installed at appropriate positions in the building. The air conditioner receives the measurement data from the above sensor and controls the inside of the building so that the temperature, humidity, and air flow are predetermined.
For such a sensor, a wireless sensor is used when the power supply line cannot be installed or is extremely difficult due to the mounting position.

FIG. 4 shows an example of the form of a sensor with a wireless communication function. In this system, the wireless sensor 1 includes a measurement unit 2 and a setting / operation unit 3. The wireless sensor 1 is equipped with a plurality of sensors 4 for measuring the current temperature, humidity, air volume, etc. in the building, and the measured data is input to the measuring unit 2. The measurement unit 2 edits the data according to the contents set by the setting / operation unit 3 and transmits the data from the antenna 5.

The data receiving device 7 installed on the back side of the ceiling 6 receives wireless information from the wireless sensor 1 sent from the antenna 5 by the antenna 8 and demodulates it, and then, via the bus 9, the air conditioning control device. Etc. to a higher-level device.

[0005]

In such an integrated wireless sensor 1, since the sensor 4 is housed in the same housing as the measuring unit 2 and the setting / operating unit 3, the indoor temperature, that is, the ambient temperature, is measured. In order to measure, it is necessary to place it in the vicinity of a person living in the building, that is, living environment, and in order to measure the temperature in the room accurately, the sensor 4 should not be surrounded by objects such as documents.

However, since the wireless sensor 1 is operated by the air conditioner, if the operator sets the temperature and humidity, there is no need to operate it thereafter, and since the wireless sensor is rarely used, the operator puts an object on it. However, it was placed behind the book, and the measurement by the built-in sensor might be inaccurate.

The present invention has been made in view of the above points, and its object is to expose the sensor 4 to the environment by expanding the range of use, increasing the frequency of use, and always keeping it handy for convenient use. It is to realize a wireless sensor for controlling an air conditioner that can accurately measure environmental conditions.

FIG. 1 is a configuration block diagram of an embodiment of the present invention, and FIG. 2 is an external view thereof. In the figure, 11 is a sensor for measuring the temperature and humidity in the building, and 12 is an interface for converting the measurement data of the sensor 11 into an electric signal and inputting it to the CPU 13.

Reference numeral 14a is a setting switch for setting the temperature and humidity in the air conditioner, and 14b is an input switch for inputting numbers, English characters, katakana, and other operation symbols to the CPU 13.

15 is input by the operation switch 14a,
A modem that modulates a high-frequency signal with the setting data edited by the CPU 13, and a radio unit 16 that wirelessly transmits the modulated signal output from the modem 15 to the data receiving device 7 (shown in FIG. 4).

Reference numeral 17 is an internal memory provided inside the apparatus for storing data such as numbers input from the operation switch 14 and data such as English characters and katakana, and 18 is for displaying the time on the display unit 19. It is a real-time clock that generates a clock.

Reference numeral 20 is an external memory that can be replaced to realize a word processing function, a game function, a memo pad function, and the like. Next, the operation of the embodiment configured as described above will be described. The sensor 11 measures temperature and humidity and inputs the data into the CPU 13 via the interface 12. CP
U13 calculates and edits the measurement data and supplies it to the modem 15. The modem 15 modulates a high frequency signal with the input measurement data and then transmits a radio wave from the antenna 5 via the wireless unit 16.

The receiving device 7 receives the transmitted radio wave and inputs it to the air conditioner via the bus 9 to control the operation of the air conditioner (shown in FIG. 4). The real-time clock 18 generates a clock and inputs it to the CPU 13. The CPU 13 integrates the input clocks, converts them into a time signal, and displays them on the display unit 19.
To display.

The setting switch 14a inputs the values of temperature and humidity controlled by the air conditioner. The CPU 13 converts the input numerical value into a control signal for the air conditioner.
