DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air-conditioning control method and apparatus used for office buildings, houses, and the like, and more particularly, to transmitting environmental information such as temperature and humidity of an air-conditioning control space by wireless communication. The present invention relates to an air-conditioning control method and apparatus that perform air-conditioning control of an air-conditioning control space based on transmitted environmental information.

In the air-conditioning control system disclosed in Japanese Patent Application Laid-Open No. 4-121546, a sensor for measuring temperature and humidity is built in a living space, and the measured value of the sensor is periodically measured by radio waves in a specific frequency band. An operating device for transmitting from the transmitter is provided, and a radio wave transmitted from the transmitting device of the operating device is received by the receiver, and the air conditioner that inhales and ventilates the living space based on the signal received by the receiver. The controller is configured to control an operation amount by the controller.

According to such a configuration, transmission and reception of signals between the operating device and the controller of the air conditioner are performed by wireless communication, so that wiring between the operating device and the air conditioner can be omitted, and wiring costs can be reduced. Can be reduced.

[0005] In addition, since the operating device can be freely moved in the living space, it is possible to freely control the temperature and humidity of the required place.

However, since the transmitter of the operating device is driven by a battery, how to extend the life of the battery becomes a problem.

Therefore, in the above-mentioned conventional configuration, the temperature and humidity measurement values measured and transmitted last time during the periodic communication for transmitting the measurement values of the sensor are compared with the measurement values measured this time. When the value exceeds a certain value, the above-mentioned periodic communication is performed, and when the value is less than the certain value, the above-mentioned periodic communication is not performed to reduce battery consumption.

[0008]

However, in the above-mentioned conventional configuration, if the difference between the previously measured and transmitted measured value and the currently measured value does not exceed a certain value, communication by the operating device is performed. Therefore, when the amount of change in temperature or humidity is small, there is a case where communication by the operation device is not performed for a considerably long time.

By the way, the controller of this type of air conditioner is configured to monitor an abnormality of the transmitter of the operating device at the time of communication by the operating device.

When the wireless communication with the master station 1 is completed, the flow returns to step 202 to enter the low power consumption mode.

According to such a configuration, step 207 is executed.
Even if the measured temperature does not exceed the previous temperature, that is, it is determined that the temperature transmitted by the previous communication does not exceed a predetermined value, it is determined in step 208 that 30 minutes have elapsed since the previous communication. Wireless communication is forcibly performed between the slave station 2 and the corresponding master station 1, so that each slave station 2 and the corresponding master station 1 have at least 30 minutes. Wireless communication is performed once.

As described above, the management computer 6 connected to the controller 5 monitors the communication state between each master station 1 and each slave station 2.
If there is a slave station 2 that does not perform wireless communication for more than a minute, the management computer 6 can recognize that the slave station 2 is not operating, that is, abnormal.

As described above, in this air-conditioning control system, no matter how the environmental data changes, at least once every 30 minutes between each slave station 2 and the corresponding master station 1. Is configured to forcibly execute the wireless communication.
For example, at the time of failure diagnosis or the like, it is possible to determine the abnormality of each slave station 2 without individually inspecting each slave station 2, thereby making it possible to determine the abnormality at the time of maintenance. Cost can be reduced.

This is very effective in an air conditioning control system accommodating a large number of slave units 2 as shown in FIG. 1 or FIG.
