Embodiment Hereinafter, a temperature and humidity display setting device according to an embodiment of the present invention will be described with reference to the drawings of FIGS.

FIG. 1 is a block diagram showing a configuration of a temperature and humidity display setting device according to an embodiment of the present invention.

In FIG. 1, a transmitter 8 that emits an infrared signal into a space and transmits a signal receives a temperature and humidity sensor 3 that detects and measures indoor temperature and humidity, and a measured value of the temperature and humidity detected by the temperature and humidity sensor 3. The temperature and humidity display section 4 to be displayed and the air conditioner (second
(Shown in the figure), a temperature setting unit 5 for setting the operation to a constant room temperature, a temperature setting value display unit 6 for inputting and displaying the temperature setting value set by the temperature setting unit 5, and the temperature and humidity sensor An infrared transmitting unit 7 which receives two signals of the temperature and humidity measurement value detected in 3 and the temperature setting value measured in the temperature setting unit 5 and converts the signal into an infrared signal and transmits an emission signal to the space;
It has a battery 1 for supplying drive power to the portion, and an infrared transmitting section 7 has an address for individually identifying which transmitter 8 the plurality of transmitters 8 have sent, and the infrared transmitting section 7 transmits the address. A first setting switch 2 for setting a time interval of a transmission cycle for preventing an infrared signal from interfering and causing an erroneous signal is connected. The first setting switch 2 is a dip switch (not shown) for setting the address. ), An oscillating circuit (not shown) for transmitting at a transmitting cycle based on the address value set by the dip switch, and the frequency of the oscillated waveform is divided. And a counter (not shown) that outputs a control signal to be transmitted. Accordingly, the infrared transmitter 7 converts the temperature set value each time the temperature is set by the temperature setting unit, and converts the measured temperature and humidity values into an infrared signal together with an address signal at set fixed time intervals, and radiates and transmits them to the space. It has a configuration.

Next, the receiver 12 which receives the infrared signal emitted to the space from the transmitter 8 has a converter 9 for converting the received infrared signal into a temperature / humidity measurement value or a temperature set value and an address signal.
And a second setting switch 11 for setting and outputting the address of the receiver 12, receiving the address value output from the second setting switch 11, the address value input from the conversion unit 9, and the temperature set value or temperature / humidity set value. A comparison unit 13 that compares and determines whether both addresses match, and outputs an input signal if they match, receives a signal from the comparison unit 13 and receives a temperature / humidity measurement value or a temperature set value and converts the temperature / humidity value into an air conditioner (No. (Shown in FIG. 2).

The operation of the temperature and humidity display setting device configured as described above will be described below.

First, the temperature and humidity are measured by the temperature and humidity sensor 3 of the transmitter 8, and the measured temperature and humidity are output to the temperature and humidity display unit 4 to display the temperature and humidity. Next, the measurement value from the temperature / humidity sensor 3 is output to the infrared transmission unit 7, converted into an infrared signal by the infrared transmission unit 7, and transmitted at the time interval set by the first setting switch 2. The first setting switch 2
Is transmitted together with the address set in advance to the infrared transmitting unit 7. Similarly, when the temperature is set by the temperature setting unit 5, the temperature setting unit 5 outputs the temperature set value to the temperature set value display unit 6 and outputs the temperature set value to the temperature set value display unit 6.
Use to display the temperature setting. Next, the temperature setting value is output to the infrared transmitting unit 7, which converts it into an infrared signal for transmission. The signal at that time is transmitted together with the address sent to the infrared transmitting unit 7 set in advance in the first setting switch 2. The battery 1 supplies drive power to each part of the transmitter 8.

Next, the receiver 12 receives the infrared signal sent from the transmitter 8 by the converter 9, converts and demodulates the infrared signal, and transmits the address of the transmitter 8 and the same as the temperature / humidity measured value or the temperature set value. Return to the address of the transmitter 8. When the demodulated signal is output to the comparison unit 13, the comparison unit 13 outputs a second setting switch set in advance corresponding to the transmitter 8.
Only when the address received from 11 is compared with the address of the received signal, a signal is output from the comparing unit 13 to the transmitting unit 10 and the signal of the temperature set value or the measured temperature / humidity signal is incorrectly transmitted from the transmitting unit 10 to the air conditioner. It is transmitted without being performed.

FIG. 2 shows an example of installation of a temperature and humidity display setting device in one embodiment of the present invention. In FIG. 2, a plurality of transmitters 8a to 8c are arranged for each zone, and a plurality of receivers 12a to 12c are also mounted on the ceiling correspondingly.
Multiple units are connected to one of 12a to 12c. Transmitter 8a
8c and receivers 12a to 12c have addresses determined for each zone, and are set to addresses 1, 2, and 3, respectively.

The operation of the temperature and humidity display setting device installed as described above will be described below.

First, the temperature and humidity measurement values are transmitted from the transmitter 8a in the zone 1 and received by the receiver 12a, and the measured values are transmitted to the air conditioner 14, whereby the zone 1 is air-conditioned. Similarly, the zones 2 and 3 are also air-conditioned. Although the air conditioning zones are divided as in this example, in places where there is no partition on the floor, signals from the transmitters 8a to 8c in each zone may erroneously enter the receivers 12a to 12c in the adjacent zone. Even in such a case, signals in other zones can be prevented from being accepted by putting an address in the transmission signal. Also, the time interval for transmitting the temperature and humidity measurement values at a constant period is changed for each zone so that the interval is 30 seconds in zone 1, 31 seconds in zone 2 and 32 seconds in zone 3, for example, to cause interference. It is possible to prevent measurement values or setting values from being erroneous.

According to the present invention, as is apparent from the above description of the embodiment, the transmitter has the first setting switch and the receiver has the unique address by the second setting switch. By changing the time interval for periodically transmitting the infrared signal of the measured temperature / humidity value for each pair of the transmitter and the receiver according to the address, it is possible to avoid interference at the receiver and to receive the signal incorrectly. Plural temperature and humidity display setting devices can be installed and control signals can be transmitted in response to the installation of multiple air conditioners that control each zone on the building floor, Greater effects can be obtained.
