The telecontrol device 5A in the room 1A on the first floor is connected to a commercial power source via an AC adapter 6 and is also connected to a telephone line modular jack 7 via a cord 8. A telephone 9 is connected to the modular jack 7 in parallel.
[0025]
The telecontrol device 5B in the room 1B on the second floor is connected to a commercial power supply via the AC adapter 10. However, there is no telephone line modular jack in the room 1B on the second floor, and this telecontrol device 5B is connected to the telecontrol device 5A in the room 1A on the first floor so as to be capable of wireless communication.
[0026]
FIG. 2 shows the telecontrol devices 5A and 5B. The circuits of these telecontrol devices 5A and 5B are common.
[0027]
The telecontrol devices 5 </ b> A and 5 </ b> B include a telephone line connection unit 11 connected to the modular jack 7 and a power supply unit 13. The telephone line connection unit 11 is connected to the CPU 18 via the telephone line control unit 14, the DTMF receiver 15, the voice synthesis unit 16, and the ringer detection unit 17. The DTMF receiver 15 receives a button operation sound from the push-type telephone and inputs to the CPU 18 which button has been pressed.
[0028]
The CPU 18 includes an infrared transmission LED (output unit) 21 that transmits a telecon signal to the air conditioner, an infrared reception receiver 22 that receives a control information signal from the air conditioner, and the telecon master unit 5A, An RF module 23 enabling communication between 5B and a communication unit 25 including a built-in antenna 24 are connected, and various setting switches 27 are further connected.
[0029]
As shown in FIGS. 3A and 3B, the telecontrol devices 5A and 5B include an upper case 31, a lower case 32, and an intermediate case 33, and various setting switches 27 are provided on the surface of the intermediate case 33. is set up.
[0030]
The various setting switches 27 include a password setting and parent / child registration push button 37, a telephone ringing number setting switch 39, a parent / child changeover switch 41 for setting a telecon parent device or a telecon child device (both will be described later), a telecon Address setting switch 43 for setting the slave unit address when a plurality of slave units are installed, and a setting switch for infrared bidirectional or unidirectional setting, which is a communication mode with the air conditioners 3A and 3B, and a test operation setting switch 45. The push button 37 has a function of completing the parent-child registration by confirming the telecon master unit and the telecon slave unit set (temporarily set) by the parent-child switch 41 by communication using the communication unit 25.
[0031]
In the present embodiment, the telecontrol device 5A connected to the modular jack 7 on the first floor constitutes the telecon master unit 5a, and the telecontrol device 5B on the second floor connected to the telecon master unit 5a so as to be capable of wireless communication is the telecon control unit 5a. The subunit | mobile_unit 5b is comprised.
[0032]
The various setting switches 27 of the telecontrol device 5A (telecom control unit 5a) on the first floor are operated as follows. First, the parent-child changeover switch 41 is switched to the parent machine side. Next, a personal identification number is input by the push button 37, and the number of calls is set by the telephone call number setting switch 39. The input of the personal identification number and the setting of the number of calls are performed only by the telecon master unit 5a, not by the telecon slave unit 5b.
[0033]
In the example of FIG. 1, the setting switch 45 is switched to infrared one-way communication. For example, when the air conditioner 3A has only an infrared reception function and does not have an infrared transmission function, the air conditioner 3A is switched to this single direction.
[0034]
The various setting switches 27 of the second floor tele-control device 5B (telephone cordless handset 5b) are operated as follows. First, the parent / child changeover switch 41 is switched to the handset side. Next, by operating the address setting switch 43, the handset address of the telecon handset 5b is set. In the example of FIG. 1, the setting switch 45 is switched to infrared bidirectional communication.
[0035]
As described above, after the switches of the setting switch 27 in the telecon master unit 5a and telecon slave unit 5b are operated, the push buttons 37 of these telecon master unit 5a and telecon slave unit 5b are pressed almost simultaneously, As a result, the parent-child registration of these telecon master unit 5a and telecon slave unit 5b is completed. By this parent-child registration, the “telephone address”, “slave unit ID” of the telecon slave unit 5b, and “communication form with the air conditioner 3B” by the telecon slave unit 5b are stored in the telecon master unit 5a. The “telephone unit ID” of the telecon unit 5a is stored in the telecon unit 5b.
[0036]
Only when the parent-child registration is completed between the telecon master unit 5a and the telecon slave unit 5b, communication using the communication unit 25 is executed between the telecon master unit 5a and the telecon slave unit 5b with reference to each ID. The telecon master unit 5a can control the air conditioner 3A as an electric device, and the telecon slave unit 5b can operate by communicating with the telecon master unit 5a to control the air conditioner 3B as an electric device. And Communication using the communication unit 25 is not executed between the telecon master device 5a and the telecon slave device 5b for which parent-child registration has not been completed (a signal is ignored even if it is received). For this reason, for example, even if the same telecontrol device is used in a neighbor, it is possible to prevent interference with the neighbor telecontrol device.
[0037]
The parent-child registration procedure by the telecon master unit 5a and telecon slave unit 5b is executed as shown in (1) to (4) in FIG.
[0038]
(1) First, the telecon master unit 5a which is set as a master unit by the parent-child selector switch 41 and whose push button 37 is pressed is set as a slave unit by the parent-child selector switch 41, and the slave unit address by the address setting switch 43. Since the ID of the telecon handset 5b for which the ID is set is unknown, a registration request signal is transmitted to the telecon handset 5b without ID (for example, “000000”). The telecon handset 5b whose push button 37 is pressed almost simultaneously with the telecon base unit 5a receives the registration request signal, and only within a predetermined time when the push button 37 is pressed, Store and register the base unit ID. This parent device ID is one of “000000” to “999999” (for example, “000001”).
[0039]
(2) Next, the telecon handset 5b transmits a registration reply signal with the base unit ID of the telecon base station 5a to the telecon base station 5a that has transmitted the registration request signal. The contents of this registration reply signal are the “slave unit ID”, “slave unit address”, and “communication form with the air conditioner (bidirectional or unidirectional communication type by infrared rays)” of the transmitted telecon unit 5b. Yes, these pieces of handset information are stored and registered in the telecon base unit 5a. The child device ID is one of “000000” to “999999” (for example, “000002”).
[0040]
(3) The telecon master unit 5a that has received the registration reply signal transmits a registration confirmation signal to the telecon slave unit 5b that has transmitted the registration reply signal using the slave unit ID of the telecon slave unit 5b.
[0041]
(4) The telecon handset 5b that has received the registration confirmation signal transmits a registration completion signal to the telecon base station 5a that has transmitted the registration confirmation signal, thereby completing the parent-child registration.
[0042]
Here, in the above (1), the telecon handset 5b receives the registration request signal, and within a predetermined time when the push button 37 is pressed, “the push button 37 is pressed for a certain time (2 to 5 seconds). If the “push button 37 is pressed once in a short time”, it is within a certain period of time (for example, 5 to 5). Within 10 seconds).
[0043]
Thus, the parent-child registration is completed between the telecon master unit 5a and the telecon slave unit 5b only within a predetermined time when both push buttons 37 of the telecon master unit 5a and the telecon slave unit 5b are pressed almost simultaneously. With this configuration, even when the parent-child registration is performed almost simultaneously with the neighbor tele-control device, it is possible to avoid interference with the neighbor tele-control device during the parent-child registration.
[0044]
Further, when the push button 37 is pressed between the telecon master unit 5a and the telecon slave unit 5b to execute the above-mentioned parent-child registration, the telecon master unit 5a and the telecon slave unit 5b transmit the communication unit 25. The transmission output of the signal (radio wave) is reduced compared to a normal case other than the time of parent-child registration. This also reduces the reach of signals (radio waves) in this parent-child registration when parent-child registration is performed almost simultaneously with the neighbor, thus suppressing interference with the neighbor during this parent-child registration. Is done.
[0045]
Further, in the example of FIG. 1, there is one telecon slave unit 5 b, but in this system, a plurality of telecon slave units 5 b can be connected to one telecon master unit 5 a. When a plurality of telecon slave units 5b are connected in this way, the parent / child registration performed with one telecon master unit 5a is sequentially performed for each telecon slave unit 5b. Thereby, the subunit | mobile_unit information of the several telecon subunit | mobile_unit 5b is registered into the one telecomputer subunit | mobile_unit 5a.
[0046]
Further, the telecon master unit 5a is configured to transmit spontaneously to the telecon slave unit 5b only at the time of parent-child registration. In other words, the telecon master unit 5a does not transmit a signal to the telecon slave unit 5b unless it receives an input from the telephone line at normal times other than when the parent / child unit is registered, and the telecon slave unit 5b waits for a signal from the telecon master unit 5a. is doing. Thereby, transmission between the telecon master unit 5a and the telecon slave unit 5b is suppressed to the minimum necessary, so that power consumption by the telecon master unit 5a and the telecon slave unit 5b is reduced.
[0047]
In addition, when the slave unit address of the telecon slave unit 5b is changed after the above parent-child registration is completed, the telecon master unit 5a re-registers the slave unit address of the registered contents (that is, slave unit information) related to the telecon slave unit 5b. It is configured to rewrite the changed slave unit address without performing registration.
[0048]
That is, the communication between the telecon master unit 5a and the telecon slave unit 5b stores the IDs of the telecon master unit 5a and the telecon slave unit 5b, respectively. This is executed using the parent-child ID and the child machine ID. For this reason, even if the actual address of the telecon handset 5b does not match the address of the handset registered (stored) in the telecon handset 5a, the telecon handset 5a and the telecon handset 5b Since communication is not hindered, there is no need to perform parent-child registration again. At this time, the telecon master device 5a only needs to rewrite the slave device address stored at the time of parent-child registration with the changed slave device address, and the usability of the telecontrol devices 5A and 5B is improved.
[0049]
Further, when the user operates the air conditioners 3A and 3B via at least one of the telecon master unit 5a or the telecon slave unit 5b using a telephone line from the outside, the CPU 18 of the telecon master unit 5a sends to the user. The guidance is switched according to the communication mode (unidirectional or bidirectional communication type using infrared rays) with the air conditioners 3A and 3B controlled by the telecon master unit 5a and the telecon slave unit 5b, respectively.
[0050]
For example, in FIG. 1, the telecon master unit 5a and the air conditioner 3A are unidirectional communication modes in which only the telecon master unit 5a communicates with the air conditioner 3A. The telecon slave unit 5b and the air conditioner 3B are bidirectional communication forms in which communication is performed between the telecon slave unit 5b and the air conditioner 3B. In the case of bidirectional communication, the CPU 18 of the telecon master unit 5a selects guidance including “confirmation” of the operating state of the air conditioner, and in the case of unidirectional communication, “confirms”. Select guidance that does not include the effect.
[0051]
The switching of the guidance by the telecon master unit 5a can also be executed for the telecon slave unit 5b in the parent-child registration between the telecon master unit 5a and the telecon slave unit 5b. The communication mode with 3B is made possible by being stored in the telecon master unit 5a.
[0052]
Next, the operation executed by the CPU 18 of the telecon master unit 5a with the user via a telephone line will be described with reference to FIG.
[0053]
When a phone call is made from a mobile phone, PHS, public telephone, etc., voice guidance is given as “Ping Pong, I am out now” (S1). Here, when a preset password is input (S2), it is determined whether or not the registered telecontrol device is single (S3). This is the case where only one telecon master unit 5a is registered.
[0054]
If the telecontrol device is not a single unit in step S3, voice guidance is given as "Please enter the number of the air conditioner to be operated (that is, the air conditioner, specifically the telecontrol device)" (S4). In this system, when the number of the telecon master unit 5a is “0”, the number of the telecon slave unit 5b is “1”, and there are a plurality of telecon slave units, the address setting switch 43 sets “1”, “2”, It is numbered as “3”.
[0055]
When the number input is completed according to the guidance in step S4, it is next determined whether or not the communication modes of the telecon master unit 5a and the air conditioner 3A, and the telecon slave unit 5b and the air conditioner 3B are bidirectional ( S5).
[0056]
If the above communication mode is unidirectional, press “00 # for air conditioner stop, 01 # for air conditioning, 02 # for heating, 03 # for dehumidification”. (S6).
[0057]
If the above communication form is bidirectional, press “00 # for air conditioner stop, 01 # for cooling, 02 # for heating, 03 # for dehumidification, 04 # for confirmation.” Is voice-guided (S7).
When the stop “00 #” is pressed after step S6 or S7, the operation of the air conditioner is stopped by voice guidance like “stop” (S8). In addition, when any one of the cooling “01 #”, heating “02 #”, and dehumidification “03 #” is pressed, “cooling (heating, defrosting) operation is performed. The room temperature is 30 ° C.” Etc. are voice-guided (S9).
[0058]
When the confirmation “04 #” is pressed, various information such as “Cooling operation. The room temperature is 30 ° C. The setting is 25 ° C.” is voice-guided (S 10). After this step S10, if “00 #” is pressed, the process proceeds to step S8, and if “01 #”, “02 #”, “03 #” is pressed, the process proceeds to step 9.
[0059]
After step S9, “Setting is 25 ° C. To change, press the desired temperature. To return to the beginning, press“ # ”. (S11), and when “#” is pressed, the process returns to the beginning. When the set temperature is input, the voice guidance is given as “Yes, the set temperature has been changed to 20 ° C.”. (S12).
[0060]
Therefore, according to the said embodiment, there exist the following effects (1)-(5).
[0061]
(1) Since communication is not executed between the telecontrol devices 5A and 5B (telecon master unit 5a, telecon slave unit 5b) whose parent-child registration has not been completed by pushing the push button 37, the same telecontrol device is used in the neighboring house. Even when the air conditioners 3A and 3B are operated via the telecontrol devices 5A and 5B, it is possible to prevent interference from occurring between the adjacent telecontrol devices.
[0062]
(2) Since the parent-child registration by the operation of the push button 37 is executed only within a predetermined time when both the push buttons 37 of the telecon master unit 5a and the telecon slave unit 5b are simultaneously pressed, this parent-child registration is performed. Even if this is executed almost simultaneously with the telecontrol device of the neighbor, the chance of causing interference with the telecontrol device of the neighbor can be reduced as much as possible during the parent-child registration.
[0063]
(3) At the time of parent-child registration by operating the push button 37, the transmission output of the radio wave output from the communication unit 25 of the telecon master unit 5a and telecon slave unit 5b is normal communication between the telecon master unit 5a and the telecon slave unit 5b. Therefore, even when parent-child registration is performed almost simultaneously with the telecontrol device of the neighbor, the reach of radio waves at the time of parent-child registration is shortened. Interference with the control device can be suppressed.
[0064]
(4) Since the telecon master unit 5a transmits spontaneously to the telecon slave unit 5b only at the time of parent-child registration, transmission from the telecon master unit 5a to the telecon slave unit 5b is minimized. For this reason, it is possible to reduce the power consumption by the telecon master unit 5a.
[0065]
(5) When the address of the telecon handset 5b is changed after the parent-child registration is completed, the telecon base station 5a changes the address of the registered content related to the telecon handset 5b without executing the parent-child registration again. Therefore, the usability of the telecontrol devices 5A and 5B can be improved.
[0066]
As mentioned above, although this invention was demonstrated based on the said embodiment, this invention is not limited to this.
[0067]
【The invention's effect】
The telecontrol device according to the present invention can prevent interference with a neighboring telecontrol device when an electric device is operated via a plurality of telecontrol devices.
