Embodiment Construction

[0015] Such as figure 1 As shown, in the first embodiment of the present invention, the network-type air conditioner remote monitoring system includes an upper computer, a modem of the upper computer, a modem of a lower computer and a lower computer, and the modems are all connected to the public telephone network.

[0016] The upper computer is a PC connected to a modem through an RS232 interface.

[0017] The lower computer is an air conditioner, and its control circuit has a CPU that plays the main control role. The CPU receives various detection signals and controls the operation of the compressor, fan, motor, etc. through the CPU, thereby realizing the control of the air conditioner . In this embodiment, the air conditioner directly serves as the lower computer to communicate with the upper computer. Such as figure 2 As shown, in the control circuit of the air conditioner, a data processing unit is also provided. The data processing unit can communicate with the main contro...

Abstract

This invention provides a network remote monitor system to air conditioners including an up computer and an air conditioner as the down computer in which the control circuit of the said air conditioner comprises a microprocessor CPU, the said up computer is one connecting with a modem via a communication interface. The control circuit of the said air conditioner also comprises a data processing unit with move than two communication interfaces connecting with CPU of the air conditioner by the interface and connecting with the modem by another interface. The said modem is connected with public phone network providing data and information transfer between the up and down computers.

Description

Technical field [0001] The invention relates to the field of remote monitoring of air conditioners. Background technique [0002] The so-called remote monitoring of the air conditioner refers to the technology of transmitting data and information between the air conditioner and the remote central control device through the communication line, so as to realize the remote monitoring of the air conditioner. Air conditioner remote monitoring technology is generally used in the following occasions, such as: unattended transfer stations, base stations, launching stations, computer rooms, archives, warehouses, certain offices, hotels, etc. In the prior art, most of the remote monitoring systems for air conditioners use dedicated lines for communication, such as central air conditioners, and the monitoring distance is limited and the operation is inconvenient. Patent ZL99208154.8 "Network Air Conditioner" discloses a network air conditioner, that is, a system that uses telephone communic...
