Abstract

PURPOSE:To obtain good effective control by wireless remote control system as well as shorten the processing time of one loop by processing data for each discriminating code. CONSTITUTION:Data A and data B are sent, together with each discriminating code added by a codifying processor A and a codifying processor B in each subsidiary micro computer, out from a transmitter. The data so transmitted are received by the receiver of the controller for air conditioner and sent out to the discriminating coding section of the main micro computer. In the discriminating coding section, it is judged whether the discriminating codes added to the data are A or B and the input of data is also judged. The data are sent out to the data processor A or B. After data A are processed firstly, data B are input.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an air conditioner, and particularly to an air conditioner equipped with a wireless remote control device suitable for use when a large amount of data is transmitted by a wireless remote control or when multiple remote controllers are used. Regarding air conditioners.

[Background of the Invention] - A wireless remote control device converts the data to be transmitted into a code for the wireless remote control, and transmits it as serial data. Therefore, the receiving side also had to convert the transmitted data into appropriate data in order to process it.

Furthermore, since the data is transmitted as serial data, as the number of data increases, the length of the serial data naturally increases. However, conventional wireless remote control devices for air conditioners do not have identification codes. Therefore, if a large amount of data is sent at once, the processing time will increase by that amount of data, which will affect other processes.Also, since the discrimination code method is not used, different pieces of data will be sent to different wireless I couldn't send it using the remote control.

Regarding conventional air conditioner wireless remote control devices,
This will be explained with reference to FIGS. 4 to 6. FIG. 4 is a block diagram of the conventional system. To explain the case where data B is added to the conventional data A, each piece of data is input to the encoding processing section of the sub-microcomputer, and the encoded data is transmitted from the transmitting section. A transmission time chart at this time is shown in FIG. FIG. 5 shows that the length of the transmitted data (time) T' has increased. The transmission data shown in FIG. 5 is received by the receiving section of the air conditioner control section shown in FIG. 4, and output to the data processing section. FIG. 6 shows a processing flowchart in the data processing section. FIG. 6 shows that only data processing is performed while there is data input. Based on the data processed by the data processing unit shown in FIG. 4, the data is output to peripheral devices via the output processing unit to control the air conditioner. However, according to this method, the data processing time in the main microcomputer increases in proportion to the length of the input data. Therefore, the processing time is extended by the amount of data (data B), and other controls cannot be performed during this extended period.

[Object of the Invention] An object of the present invention is to provide an air conditioner that improves the conventional problems when transmitting a large amount of long data.

[Summary of the invention]

In the present invention, a discrimination code is provided in a part of long data, and the data is divided in time and transmitted, and the data processing in the main microcomputer on the receiving side is performed in units of discrimination codes.In this way, By replacing long data with independent data and processing it, it is no longer necessary to process received data at the same time.Therefore, it is thought that there will be no influence on other controls.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. FIG. 1 is a block diagram of the present invention. A time chart of transmission data is shown in FIG. T in Figure 2
%T' indicates the same time as in FIG. t is the time during which the transmission of data A and data B is temporally divided.

FIG. 3 is a flowchart showing control of the discrimination code section and data processing section. A discrimination code is added to data A1 and data B by a coding processing section A and a coding processing section B in each sub-microcomputer. The data to which the discrimination code has been added is transmitted from the transmitter. The data transmitted from the transmitting section is received by the receiving section of the air conditioner control section and output to the discrimination code section of the main microcomputer. In the discrimination code section,
It is determined that there is data input and whether the discrimination code added to the data is A or B, and output to the data processing section A or B, respectively. After data A is first processed, data B is input seconds later. FIG. 6 shows the processing in this main microcomputer. Therefore, other controls can be performed during that time. Further, since the processing is performed in units of discrimination codes, the processing time may be T and T' seconds, respectively. After data processing is performed as described above, the output processing unit converts the signal into a control signal and outputs it to peripheral devices to control the peripheral devices that constitute the air conditioner. Note that the peripheral devices include a fan motor, a compressor, and the like.

According to this embodiment, since the processing is performed for each discrimination code, the ratio of the data processing time to the processing time of the control program of the entire main microcomputer can be reduced. Therefore, there is an effect that the influence on other control processing can be reduced. Further, as in this embodiment, by setting a time between each data, it is possible to send as much data as the number of discrimination codes allows.

〔Effect of the invention〕

According to the present invention, since the processing time for one loop can be shortened by performing data processing for each discrimination code, it is possible to provide an air conditioner that can be effectively controlled by a wireless remote controller.
