Description

  The present invention relates to a remote controller that transmits a combination of a plurality of types of data in a predetermined format.

  A conventional remote controller transmits a control signal by operating an operation unit such as a switch. This control signal is composed of a group of data and is configured in a predetermined format.

This control signal includes a reader, a custom code, a parity, a data code, and a trailer (see Patent Document 1 below).
Japanese Unexamined Patent Publication No. Hei 4-90634 (especially FIG. 6)

  In recent years, the number of functions of devices controlled by the remote controller has increased with respect to the data amount of the control signal, so the data amount is increased by changing the length of the control signal to correspond to the function of the device. It is considered.

  However, when the control signal is lengthened, there is a possibility that the possibility that the device fails to receive the control signal increases.

  Therefore, in order to cope with the increased data amount without changing the length of the control signal, only the first control signal having arbitrary transmission data and the second control signal having data different from the first control signal are used. A remote controller that transmits only the control signal and the combination of the first control signal and the second control signal can be considered.

  However, when the first control signal and the second control signal are transmitted in combination, the device side fails to receive the control signal, and the first control signal or the second control signal Only the control signal is received, the second control signal transmitted in combination and the first control signal are not received, and the control different from the control desired by the operator who operates the remote controller is performed. There was a risk that the equipment would do.

  Accordingly, the present invention focuses on the above-described problems, and an object thereof is to provide a remote controller capable of suppressing the length of the control signal and reducing the failure to receive the control signal.

  The present invention relates to a remote controller that transmits a control signal by combining a plurality of types of transmission data within a predetermined format, and the first control signal having the first transmission data is partially different from the first transmission data. A second control signal having second data can be transmitted subsequent to the first control signal, and it is determined whether or not the second control signal is transmitted following the first control signal. A discrimination data portion is provided in the first control signal.

  ADVANTAGE OF THE INVENTION According to this invention, the remote controller which can achieve the intended objective, can suppress the length of a control signal, and can reduce the failure of reception of a control signal can be provided.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, a first embodiment of the invention will be described with reference to the accompanying drawings.

  A remote controller (control device) 1 according to the present embodiment includes a key input unit 2, a control unit 3, a storage unit 4, a transmission / reception unit 5, and a display unit 6. A is a device controlled by a remote controller, which is an air conditioner in the present embodiment, and is controlled by a control signal from the remote controller 1.

  The key input means 2 consists of a push switch, a touch panel switch, etc., for example, and performs various operations regarding control of the air conditioner A.

  The control means 3 is mainly configured by a microcomputer, and includes a CPU for executing a predetermined program, a ROM storing the program, a RAM temporarily storing calculation results, and the like. It has a drive circuit for outputting a control signal to control the operation of the conditioner A, an interface unit for inputting a control signal from the key input means 2, and the like.

  The control unit 3 receives a control signal from the key input unit 2 and combines a plurality of types of transmission data in a predetermined format according to the state of the remote controller 1 when the key input unit 2 is operated. Is generated. Further, the control means 3 detects the operating state of the air conditioner A and causes the display means 6 to display a set state corresponding to the operating function during operation.

  The memory | storage part 4 records various data, such as the setting possible range in various driving functions, non-volatilely, for example, consists of EEPROM.

  The transmission / reception means 5 includes an infrared light emitting diode, an infrared sensor, and the like, and transmits the control signal of the control means 3 to the air conditioner A by an infrared transmission signal. Further, it also receives an infrared transmission signal from the air conditioner A. The transmission path of the transmission / reception means 5 may be a wired system in which the remote controller (control device) 1 and the air conditioner A are connected by a communication line.

  The display means 6 is provided with a liquid crystal display element such as a dot matrix type as a display element, and a display element whose display contents can be changed according to a setting situation is used.

  Next, communication between the remote controller (control device) 1 and the air conditioner A will be described. FIG. 2 shows a case where the remote controller (control device) 1 transmits only the first control signal C1 to the air conditioner A.

  The first control signal C1 has a limited predetermined format such as 96 bits, for example, and various data for controlling the air conditioner A are stored in this format. The data stored in the first control signal C1 is preferably frequently used data.

  For example, a “set temperature rise switch” or the like. When this switch is operated, the remote controller 1 generates a first control signal C1 having data for raising the set temperature by 1 degree Celsius, and outputs the first control signal C1 twice. The interval of the first control signal C1 output twice is 15 milliseconds. The reason why the first control signal C1 is output twice is to suppress transmission / reception failure, and the first control signal C1 may be output once.

  Further, the first control signal C1 includes a determination data portion D1 for determining whether or not a second control signal, which will be described later, is transmitted following the first control signal C1. The data part D1 stores data indicating that the second control signal is not transmitted, and a second control signal described later is not transmitted following the first control signal C1.

  In the air conditioner A, the determination data part D1 of the first control signal C1 determines that the second control signal is not transmitted following the first control signal C1, and the reception process is normally completed. I can distinguish it.

  FIG. 3 shows a case where the remote controller (control device) 1 transmits the first control signal C1 and the second control signal C2 to the air conditioner A.

  Similar to the first control signal C1, the second control signal C2 has a limited predetermined format such as 96 bits, and data for controlling the air conditioner A is stored in this format. The data stored in the second control signal C2 is preferably data that is less frequently used.

  For example, a “wind direction setting switch” or the like is operated. When this switch is operated, the remote controller 1 generates a second control signal C2 having data for changing the wind direction, and remote when the key input means 2 is operated. The first control signal C1 is generated based on the state of the controller 1, the first control signal C1 is output twice, and after a predetermined time, for example, 125 milliseconds, the second control signal C2 is output twice. . The first and second control signals C1 and C2 may be output once.

  Data indicating that the second control signal C2 is transmitted is stored in the discrimination data portion D1 of the first control signal C1 output at this time.

  From the above, all transmissions from the remote controller 1 include the first control signal C1. The first control signal C1 includes a discrimination data portion D1.

  When only the first control signal C1 is transmitted, data indicating that the subsequent second control signal C2 is not transmitted is stored in the determination data portion D1.

  The second control signal C2 is not included in all transmissions from the remote controller 1. When transmitting the second control signal C2, data indicating that there is a subsequent transmission of the second control signal C2 is stored in the determination data portion D1 of the first control signal C1.

  In the air conditioner A, by receiving the data indicating that the second control signal C2 is transmitted, the reception process is normally completed when the second control signal C2 is received after the first control signal C1. I can distinguish it.

  If the air conditioner A receives the first control signal C1 including the data indicating that the second control signal is present but cannot receive the second control signal C2, the second control signal C2 is received. It can be determined that the control signal is missing.

  Further, when the air conditioner A receives the second control signal C2 without receiving the first control signal C1, it can be determined that the first control signal C1 is missing.

  In the present embodiment, the air conditioner control device is the remote controller 1 provided separately from the air conditioner A, but the control device of the present invention is provided integrally with the air conditioner. An operation panel may be used.

  With the above configuration, the increased data amount can be handled by transmitting a control signal storing different data without changing the format length of the control signal.

  Then, it is possible to provide a remote controller capable of suppressing the length of the control signal, reducing the failure of receiving the control signal, and suppressing increase in power consumption.
