Next, the operation of the conventional centralized control system for an air conditioner configured as described above will be described. First,
The operation of the conventional air conditioner control device disclosed in JP-A-2-40441 will be described with reference to FIGS. 39 and 40. The operation of FIG. 39 will be described. A case in which the indoor temperature is controlled by an air conditioner, which is the most common air conditioning control device, will be described. The child device 112 is installed in a controlled area in the room. Further, the parent device 120 is always used as a pair corresponding to the child device 112 on a one-to-one basis, but is usually installed in a place on the same floor in the building away from the child device 112, for example, in the ceiling or another room. Therefore, the slave unit 112 and the master unit 120 are
It is usually installed several tens of meters apart from several meters separated by one wall. First, the slave 112 will be described. The power source 101 built in the slave unit 112 uses a secondary battery that is charged by an electromotive force generated when the solar cell receives sunlight or indoor lighting. A temperature measuring resistor or a thermistor is usually used as the temperature sensor 102 built in the slave unit 112, and a variable resistor or the like is used as the setting device 103. The signal converter 104 is usually the sensor 1
The deviation value between the detected value of 02 and the setting value of the setting device 103 is converted into an electric signal and output.

Now, the deviation voltage between the detected value of the sensor 102 and the set value of the setter 103 is output from the signal conversion circuit 104 of FIG. 39 and input to the AD converter 105. The AD converter 105 converts the input analog voltage value into digital control data (hereinafter referred to as control data) of, for example, 1 bit for the polarity code and 3 bits for the data value, which is a total of 4 bits, and outputs the digital control data. To do. The slave code setting unit 106 sets a digital code having a bit number U corresponding to the number of control targets. For example, when the number of control targets is 127 or less, a slave unit identification code of 7 bits is set. The encoder 107 generates a transmission code by the 7-bit child code from the child code setting unit 106 and the 4-bit control data from the AD converter 105. The data shift-out from the encoder 107 is performed in synchronization with the clock signal supplied from the timing circuit 109, and the transmission code thereof has the prefix code as the head and the end code as the end, and the middle thereof. 1 code in which data is inserted and a pause period of 2 bits is placed after the end code is supplied to the transmitter 108 as a serial transmission code of 3 codes repeated 3 times. Timing circuit 1
Reference numeral 09 is a circuit that receives power from the power supply 101 at all times, and performs timing control for the slave unit 112 to intermittently transmit at regular transmission intervals T0 (for example, 3 minutes). Therefore, the timing circuit 109 also generates a required timing control signal and controls power supply to other devices for power saving.

The encoder 107 transmits the transmission code to the transmitter 10
8, the transmitter 108 generates a frequency shift modulated wave (FS modulated wave) based on the transmission code. As the FS modulated wave, for example, a basic frequency f1 of 270 MHz is associated with the code "1", and a frequency f2 (265 MHz or 275M) is obtained by shifting the frequency Δf (for example, 5 MHz).
(Hz) is generated corresponding to the code "0". Then, the generated FS modulated wave is radiated into the air as a transmission radio wave 113 via the transmission antenna 110. This transmitter 1
The required transmission power of 08 considers various characteristics (directional characteristics, antenna gain, etc.) of the transmitting antenna 110 and the receiving antenna 114 so that the base unit 120 can receive at a distance of about 100 meters separated by one wall. Designed above.

Next, the base unit 120 will be described. Base unit 1
20 is installed several meters to several tens of meters apart from the slave unit 112 by one wall, and is often supplied with required power by wiring from an indoor AC power supply. The transmission radio wave 113 transmitted from the child device 112 is input to the receiver 115 via the receiving antenna 114. The receiver 115 receives and amplifies the input FS modulated wave and then demodulates it. Therefore, the receiver 115 is a receiving amplifier, a pair of band pass filters (one pass frequency f1 is 270 MHz, the other pass frequency f2 is 265 MHz or 275 MHz),
It is composed of a limiter and a demodulator. The output signal which is normally received by the receiver 115 and demodulated is just the encoder.
It is the same as the output signal of the DA 107. The output signal of this receiver is supplied to the code collator 117. Master code setter 11
The same 7-bit parent code as the child code set in advance in the child code setting unit 106 is set in 6, and this parent code is supplied to the code collating unit 117. Code collator 117
Is a check bit check (even parity or odd parity check) for each code from the data of three codes input from the receiver 115, and the received 7-bit child code and the master code setter 116. The collation and coincidence check with the parent code of 7 bits is performed. That is, the master 120 checks whether the data is correctly received from the only slave 112 having the same slave code as its own master code. The code collator 117 extracts only 4-bit control data from each of the codes that have passed both the check bit check and the code match check of the master unit from the input three-code data. It is supplied to the collator 118. Therefore, if all three codes pass, three control data are supplied. If one code fails, only two control data will be supplied from the passed two codes. The data collator 118 has a built-in logic circuit for detecting data coincidence, detects a coincidence of at least two data among three or two control data, and in case of passing, this The 4-bit control data for which a match is obtained is supplied to the control circuit 119. The control circuit 119 decodes the input 4-bit control data, selects one of the control signals divided into 16 control stages, and outputs it to the air conditioner 121.

40 will be described. Air conditioner 121A, 1
21B, 121C and base units 120A, 120B, 120C
Are the interior partition wall 151C and the building exterior wall 150, respectively.
It will be installed in the room surrounded by D. In addition, child machine 112A, 1
12B and 112C are outer walls 150A and 15 of the building, respectively.
It is installed inside 0B and 150C. The parent device 120A only needs to be able to receive the transmission radio wave 113A from the child device 112A, and similarly, the parent device 120B need only be able to receive the transmission radio wave 113B from the child device 112B. Similarly, the parent device 120C need only be able to receive the transmitted radio wave 113C. If the parent device 120A is currently receiving the transmission radio wave 113A from the child device 112A and at the same time receives the transmission radio wave 113B or 113C, an interference occurs and a kind of radio wave interference occurs. As a simple method for avoiding this radio wave interference, the cordless handset 1
The transmission cycles of 12A, 112B, and 112C are set to be slightly different. For example, the transmission cycle of the slave 112A is 2 minutes and 50 seconds, and the transmission cycle of the slave 112B is 3 minutes.
The transmission cycle of the minute handset 112C is set to 3 minutes and 10 seconds, and is set to be different by 10 seconds. In this way, by setting the transmission cycle of each slave unit to be slightly different,
For example, even if the slave unit 112A and the slave unit 112B transmit at the same time in a certain time zone, the transmission is performed in the separated time zones in the next transmission cycle. Therefore, even if the parent device cannot receive correct data due to interference in a certain time zone, it can receive correct data in the next transmission cycle. Also, since each slave unit transmits only 27 ms in about 3 minutes, the duty is 27 × 10 −3 / 3 × 60−1.5 × 1.
It is as small as 0-4, and the probability that a plurality of slave units simultaneously transmit in the same time zone is extremely small. Therefore, even if the control of the air conditioner in this case is the same control as before, no particular trouble will occur.

Next, the operation of the conventional control device for an air conditioner disclosed in Japanese Patent Laid-Open No. 202202/1990 will be described with reference to FIG. Normally (at home), the operation of the indoor unit 101 is controlled by detaching the wireless transmitter 202 from the accessory device 203 and holding and operating it. At this time, a call received from the external telephone 207 can be received by the internal telephone 204. On the other hand, when going out, the wireless transmitter 202 is attached to the accessory device 203. Then, by making a call from home to the home and operating according to a predetermined procedure, a signal from the telephone is sent to the auxiliary device 20.
It is sent to the wireless transmitter 202 via 3 and the operation control of the indoor unit 201 can be performed.

In step 235, the radio wave is received and demodulated in advance, and in step 235, the data demodulated in step 234 is stored in advance in the master unit identification code storage unit 21 (or the slave unit identification code storage unit 31). A state in which an existing identification code is detected, step 236
Is a state in which when the previously stored identification code is detected in step 235, it is determined that the communication is to the local station and data is received, and in step 237, the frequency priority is set based on the reception operating frequency fR. State, step 238 ends the reception process and returns to normal control, step 239 does not detect the radio wave of the reception operation frequency fR in step 233, or the identification code stored in advance is used in the step. This is a state in which the reception operating frequency fR is changed when no detection is made at 235.

Next, the operation of the embodiment of the centralized control system for an air conditioner configured as described above will be described by taking the case where the air conditioner management device 8 is set for operation. For example, as shown in FIG. 1, an air conditioning unit 1, a local remote controller 1c which is a setting input and status display output device of the air conditioning unit 1, an air conditioning unit 2, and a setting input and status display output device of the air conditioning unit 2. Remote controller 2c
An air conditioning unit (not shown) and a remote controller (not shown) constitute an air conditioning block (A) 3, and each device is in charge of air conditioning in each area of the air conditioning block (A) 3.
Similarly, in the air conditioning block (B) 5 and the air conditioning block (C) 7, an air conditioning unit 4, a local remote controller 4c which is a setting input and status display output device of the air conditioning unit 4, and an air conditioning unit not shown. The air conditioning block (B) 5 is constructed by a remote controller (not shown), and the air conditioning unit 6
The local air conditioner 6c which is a setting input and status display output device of the air conditioning unit 6, an air conditioner unit (not shown), and an air conditioner block (C) 7 (not shown).
And each device is in charge of air conditioning in each area of the air conditioning block (B) 5 and the air conditioning block (C) 7. Each device in the air conditioning block (A) 3, the air conditioning block (B) 5, and the air conditioning block (C) 7 sends and receives data to and from the air conditioning management device 8 by using radio waves. Centralized control and status monitoring are performed by the management device 8.

The air conditioning management device 8 is provided with a master unit 20 as shown in FIG. 8, and when an operation command is issued to a specific air conditioning unit, for example, when an operation command is issued to the air conditioning unit 1. The master unit processing unit 27 through the central processing unit 28 of the air conditioning management device, together with the identification code of the slave unit 30 included in the air conditioning unit 1 stored in advance by the parent unit identification code storage unit 21,
The operation command is transmitted to the transmitting means (a) 23, and the transmitting means (a) 23 transmits it to the air conditioning unit 1 by using radio waves. In addition, each air conditioner is shown in Figure 9.
In the air conditioning unit 1, for example, the parent device 2 of the air conditioning management device 8 is provided.
When the receiving unit (b) 32 receives the operation command from 0, the slave unit processing unit 36 stores the identification code transmitted together with the operation command transmitted by using the radio wave in the slave unit identification code storage unit. Only when it matches the identification code of its own stored by the unit 31, this is received as an operation command for the air conditioning unit 1 and transmitted to the air conditioning unit central processing unit 37. The air conditioning unit central processing unit 37 operates the air conditioning unit 1 based on the data transmitted from the slave unit processing unit 36. Further, the slave unit processing unit 3
6 transmits data indicating that the operation command has been received to the transmitting means (b) 33 together with its own identification code stored in the slave unit identification code storage section 31, and this transmitting means ( In b) 33, this is used as a response signal for the base unit 20.
Is transmitted using radio waves. Further, in the case where the identification code transmitted together with the operation command transmitted by using the radio wave to the slave unit 30 does not match with its own identification code stored in advance by the slave unit identification code storage unit 31. It is determined that it is not control information for the air conditioning unit 1, and the invalid data is set.

In the parent device 20 shown in FIG. 8, the receiving means (a) 23 receives the response signal from the child device 30,
It is transmitted to the parent device processing unit 27. In the master unit processing unit 27, the identification code of the transmitted data is the identification code of the slave unit 30 included in the air conditioning unit 1 which is stored in advance by the master unit identification code storage unit (a) 21. After confirming that, the response signal reception is completed, and the operation command transmission to the air conditioning unit 1 is completed. Here, when the master device 20 does not receive the response signal from the slave device 30, or when normal transmission cannot be confirmed from the received response signal, the master device 20 transmits the operation command again. . At this time, the operation of transmitting and receiving by radio waves in the parent device 20 and the child device 30 is performed by the wireless communication processing unit 1 of the parent device 20.
The wireless communication processing unit 130b of the mobile device 30a and the wireless device 30 are controlled respectively.

The operation of the wireless communication processing unit 130a of the master device 20 and the wireless communication processing unit 130b of the slave device 30 is shown in FIG.
0, the operation of the wireless communication processing unit 130 will be described. First, the transmission operation will be described. When a transmission request is generated in the processing unit 144, the data generation unit 136
The transmission code is generated in a predetermined format together with the identification code stored in the master identification code storage section 21, and the transmission control section 132 causes the transmitter 131.
To operate. In the transmission control unit 132, the transmission frequency setting unit 133 sets the frequency fT used for transmission in accordance with the priority set by the transmission frequency priority setting unit 134. At this time, the frequency with the highest priority, for example, f1 is selected. Here, when a radio wave having the transmission frequency fT = f1 already exists, the transmission frequency fT is changed to perform transmission in order to avoid interference. Then, when the transmission frequency fT is set, the receiver 137 is operated by the reception control unit 138, and the reception state is set at the frequency fT = f1,
The presence or absence of a radio wave of frequency f1 is confirmed by the radio wave detection unit 142 via the antenna 145 and the receiver 137. When the radio wave detection unit 142 does not detect the radio wave of the frequency f1, the transmitter control unit 135 operates the transmitter 131 at the transmission frequency fT = f1 and the data generation unit 136.
A radio wave whose frequency is modulated based on the transmission data generated by is generated and is radiated by the antenna 145. When the radio wave detection unit 142 detects a radio wave of the frequency f1, the transmission frequency priority setting unit 134 changes the frequency priority. For example, the priority of the frequency f1 is the lowest, the priorities of the other frequencies are moved up by one, respectively, and the frequency of the second priority, for example, f2, is the highest priority. Then, the transmission frequency setting unit 133 changes the transmission frequency fT to f2 and repeats the above setting operation. The number of frequencies that can be set by the transmission frequency setting unit 133 is n.
Then, after repeating the above setting operation n times, fT
Setting starts from = f1. The transmission control unit 132 repeats the above setting operation, and transmits at a frequency not used by another station, for example, fm. At this time, the highest priority frequency is fm, and at the end of transmission, the transmission frequency at that time is always set to the highest priority.

Next, the receiving operation will be described. When a reception request is generated in the processing unit 144, the reception control unit 1
38 operates the receiver 137. In the reception control unit 138, according to the priority set by the reception frequency priority setting unit 140, the reception frequency setting unit 139
Set the frequency fR to operate in the receiving state. At this time, the frequency with the highest priority, for example, f1 'is selected. The reception frequency setting unit 139 determines the reception operating frequency fR.
= F1 'is set, the receiver control unit 141 operates the receiver 137 at the reception operation frequency fR = f1', and puts it in a reception standby state for a fixed time. If the radio wave detection unit 142 does not detect the radio wave of the frequency f1 'even after a certain period of time, the reception operation frequency fR is changed to, for example, f2' in the reception frequency setting unit 139, and the detection of the radio wave is similarly performed. To do. Assuming that the number of frequencies that can be set by the reception frequency setting unit 139 is n, the above operation is repeated n times, and then the detection of radio waves is started again from fR = f1 '. The reception control unit 138 repeats the above operation until detecting a radio wave, and searches for the transmission frequency fT 'of the partner station. At this time, by setting the reception standby time to be longer than other frequencies in the case of the highest priority frequency, for example, f1 ',
It is set so that the detection operation by the frequency with high priority increases. While waiting for reception, the antenna 145 and the receiver 1
37, the radio wave detection unit 142 sends the frequency fm
'When the radio wave is detected and the receiver 137 demodulates the received radio wave, the data receiving unit 143 causes the receiver 137 to
The identification code is detected from the data demodulated in. The data receiving unit 143 receives the demodulated data from the master unit identification code storage unit 21 (or the slave unit identification code storage unit 3).
When the previously stored identification code is detected in 1), the reception data is transmitted to the processing unit 144, and the reception frequency priority setting unit 140 sets the frequency fm 'to the highest priority frequency. Set to. Therefore, at the end of reception, the reception frequency at that time is always set to the highest priority. Although the radio wave of the frequency fm 'is detected and the received radio wave is demodulated, the master unit identification code storage unit 21 (or the slave unit identification code storage unit 3 is used.
When the stored identification code is not detected in 1), the reception operation frequency fR is changed as in the case where no radio wave is detected, and the reception radio wave is detected. As described above, after transmission / reception, the frequency used at that time, that is, the frequency not used by another station at that time has a high priority, and the frequency detected by the other station has a low priority, and is always The frequency priority is set according to the frequency usage status at the time of the previous transmission / reception. The processing unit 144 controls the wireless communication processing unit 130 as described above, and transmits / receives data to / from another station.

Next, the operation of the wireless communication processing section 130 will be described with reference to the flowcharts shown in FIGS.
First, the transmission operation will be described with reference to FIG. Step 22
When a transmission request from the processing unit 144 is generated at 0,
In step 221, the frequency fT used for transmission is set. At this time, the frequency having the highest priority is selected according to the priority set by the transmission frequency priority setting unit 134. When the transmission frequency fT is set in step 221, the receiver 137 is operated at the frequency fT in step 222, and in step 223 it is confirmed whether there is a radio wave of the frequency fT. When the radio wave of the frequency fT is not detected in step 223, it is determined that another radio station is not using the frequency fT, and in step 224, the frequency fT is used.
At T, the transmitter 131 is operated, data is transmitted at step 225, the transmission process is terminated at step 226, and the process returns to the normal control. When the radio wave of the frequency fT is detected in the step 223, another radio station is using the frequency fT, so the frequency priority is changed in the step 227, and the frequency setting of the step 221 is returned to. Transmit at a frequency that is not used by the wireless station.

Next, the reception operation will be described with reference to FIG. When a reception request from the processing unit 144 is generated in step 230, the frequency fR used for reception is set in step 231. At this time, the highest priority frequency, for example, f1 'is selected according to the priority set by the reception frequency priority setting unit 140. Step two
When the reception operation frequency fR (here, f1 (1)) is set at 31, the receiver 137 is operated at the frequency fR at step 232, and the reception standby state for a certain time is set at step 233 to set the radio wave of the frequency fR. Check for.
If the radio wave having the frequency fR is not detected in step 233, the reception operation frequency fR is changed in step 239, the frequency setting is returned to step 231 and the above operation is repeated until the radio wave from the partner station is detected. Step 23
If the radio wave of frequency fR is detected in step 3, step 2
The received radio wave is demodulated at 34, and the identification code is detected at step 235 based on the demodulated data. When the identification code stored in advance by the master unit identification code storage unit 21 (or the slave unit identification code storage unit 31) is detected at Step 235, the demodulation data is sent to the own station at Step 236. Data is transmitted to the processing unit 144 as a data, the current frequency is set to the highest priority frequency in step 237, the reception process is terminated in step 238, and the normal state is returned to. At this time, the processing unit 144 receives the received data.
Device control and communication control according to If the previously stored identification code is not detected in step 235, the reception operation frequency fR is changed in step 239, the frequency setting is returned to step 231 and the above operation is repeated. The reception waiting time in step 233 is set according to the priority of the frequency. For example, the frequency having the highest priority is set to have a standby time longer than the other frequencies, and the radio wave detection operation using the frequency having the highest priority is maximized.

According to the invention as described above, it is possible to prevent interference between the air conditioning management device and the air conditioning unit during transmission / reception by radio waves, and to set the priority order to enable efficient frequency setting.

Example 3. In the second embodiment, the priority order of the frequencies set by the transmission frequency priority setting unit and the reception frequency priority setting unit is only moved up depending on the usage status of the frequency. For example, the parent device 20 uses the radio wave. Each time you try to transmit, you should set the specific frequency to the lowest priority and switch the priority order if the specific frequency is frequently used by other wireless devices. You can That is, the predetermined transmission frequency f
It is assumed that 1, f2, f3, and f4 are prioritized in this order with f1 as the highest rank and stored in the transmission frequency priority setting section. It is assumed that a specific frequency f2 is constantly or frequently used by an external wireless device in the air conditioning block. When the base unit 20 tries to transmit the operation command by using the radio wave, the base unit radio wave detection unit 142 outputs the frequency f1.
When the presence or absence of the radio wave of the radio wave of the radio wave is detected, it is happened to be used by another radio device, and the transmission frequency priority setting unit sets the priority order to f2, f3, f4, f.
Switch to 1. However, the frequency f2 is almost used, and the transmission frequency priority setting unit 133 switches the priority order to f3, f4, f1 and f2. If the transmission frequency is switched from f1 to f2 in this way, and f2 is switched to f3 at all times or in many cases when f2 is in use, the frequency priority setting unit judges this from past data and determines the frequency. Set f2 to the lowest priority. Therefore, after the priority setting section changes the priority order, the priority order is set to f1, f3, f4, f2. By setting the frequency f2 to the lowest priority in this way, the priority set in the transmission frequency priority setting section has a higher frequency than the frequency not used by another wireless device, so that the radio wave is used. When selecting the frequency to be used for transmission, the time can be shortened.

Similarly, with respect to the reception frequency priority setting, when the specific frequency f2 is not always or rarely used as the transmission wave by the radio wave from the base unit 20, the reception frequency priority setting unit is set to the past. Judging from the data, the frequency f2 is set to the lowest priority. By doing so, the priority set in the reception frequency priority setting unit is such that the frequency that is frequently used by the parent device 20 as the transmission wave by the radio wave is higher, so that when selecting the reception frequency, Can be shortened.

Example 4. Further, the transmission frequency priority setting unit and the reception frequency priority setting unit of the second embodiment have n frequency candidates, and the priority order is switched among them, but for example, there is a reference frequency. , If the frequency is already in use, change it to a frequency with a predetermined number added, and if this frequency is used, add the predetermined number again to change the frequency. Good. That is, there is the reference frequency f1 and the base unit 2
0 tries to transmit a driving command at this frequency f1 and the radio wave detection unit 142 detects whether the frequency f1 is already in use.
Suppose you were using 1. In response to this, the transmission frequency priority setting unit sets the frequency f1 = a predetermined value, for example, the frequency f2 = f1 + (1MHZ), which is a value obtained by adding 1MHZ, as the highest priority, and the transmission frequency setting unit follows this priority. 133 tries to transmit the driving command at the frequency f2. When it is detected again by the radio wave detection unit 142 whether or not the frequency f2 is already used, it is assumed that another wireless device happens to be using the frequency f2. In response to this, the transmission frequency priority setting unit sets the frequency f2, which is a value obtained by adding a predetermined number 1MHZ, to the frequency f3 = f2 + (1MHZ) as the highest priority, and the transmission frequency setting unit 133 operates according to this priority. Attempts to send a command at frequency f3. After that, this operation is repeated to change the frequency, and when the frequency fn reaches a certain predetermined value, it returns to the reference frequency f1.

Regarding the reception frequency priority setting unit, the frequency priority can be set in the same manner as the transmission frequency priority setting unit. Further, in the present embodiment, the predetermined number is added to the reference frequency f1, but it is of course possible to subtract it, and in addition, the priority of the reception frequency priority setting unit is changed when the priority of the transmission frequency priority setting unit is changed. The method of changing the priority order is arbitrary as long as the change can be dealt with. Further, in such a case, it is of course possible to combine with the third embodiment.

Furthermore, the data in each air conditioning block is transmitted to each air conditioning management device 8 by radio waves by each air conditioning block transmission relay device and managed by this air conditioning management device 8. The air conditioning management device 8 transmits an operation command to each air conditioning block transmission relay device by using a radio wave, and each air conditioning block transmission relay device transmits the operation command to each corresponding air conditioning unit based on the received operation command. Use to send and control each equipment. When an operation command is issued to the specific air conditioning unit in the air conditioning management device 8, for example, an operation command is issued to the air conditioning unit (1) 1, the air conditioning management device 8 is installed with the air conditioning unit (1) 1. The operation command is transmitted to the air conditioning block transmission repeater (A) 171 which manages the data in the air conditioning block (A) 3 using wireless radio waves.

The air conditioner management device 8 is provided with the master device 20 as shown in FIG. 2, and the master device processing section 27 via the air conditioning management device central processing part 28 causes the master device processing part 27 to identify the master device identification code. Along with the identification code of the repeater provided in the air conditioning block transmission repeater (A) 171, which is stored in the storage unit 21 in advance, the slave unit provided in the air conditioning unit (1) 1 as an operation command. The identification code and the operation command are transmitted to the command transmission means 22, and the command transmission means (a) 22 transmits this to the relay of the air conditioning block transmission relay device (A) 171 using radio waves. .

Each air conditioning block transmission repeater is provided with the repeater 180 as shown in FIG. 14, and for example, the air conditioning block transmission repeater (A) 171.
In the relay device 180 included in the command receiving unit 186, when the command receiving unit 186 receives an identification code transmitted from the master device 20 included in the air conditioning management device 8 using a radio wave, the command The receiving unit 186 determines the coincidence of the identification code via the relay processing unit 188, and the received identification code is stored in the relay identification code storage unit 181.

In the parent device 20 shown in FIG. 2, the response signal receiving means 23 receives the identification code transmitted from the relay device 180 provided in the air conditioning block transmission relay device (A) 171 using a radio wave. When received by the response signal receiving means 23, the response signal receiving means 23 determines the matching of the identification code through the master unit processing section 27, and the received identification code is stored in the master unit identification code storage section 21. The repeater 180 provided in the block transmission repeater (A) 171

Here, when the master device 20 does not receive the response signal from the relay device 180, or when normal transmission cannot be confirmed from the received response signal, the master device 20 transmits the operation command again.

The central processing unit 189 of the air conditioning block transmission relay device that has received the operation command from the master unit 20 determines the content of the command from the received operation command.

It is in a state in which the reception is transmitted by using a radio wave as a response signal.

Next, the operation will be described. First, a case where the operation is set by the general subscriber telephone set 10 installed elsewhere, for example, a case where the operation control of the air conditioning unit 2 is performed will be described. A user calls a telephone 9 which is connected to a telephone line and has a wireless transceiver, from a general subscriber telephone 10 installed in another place. The telephone 9 automatically receives a call from the subscriber telephone 10. The user is
After confirming the connection with the telephone 9, after transmitting a personal identification number and the like, an operation command for the air conditioning unit 2 which is designated in advance is transmitted by a digital signal such as a touch tone or a voice. This operation command is transmitted from the telephone 9 to the parent device 20 of the air conditioning management device 8 shown in FIG. 2 by using a radio wave. The operation command transmitted using the radio wave is received by the remote control data receiving means 25 of the parent device 20, and is transmitted to the air conditioning management device central processing unit 28 via the parent device processing unit 27. The central processing unit 28 of the air-conditioning management device performs external output such as displaying on a display (not shown) that remote control data is being received, and the master unit identification code storage unit 21 via the master unit processing unit 27. Thus, the operation command is transmitted to the remote control data transmitting means 26 together with the identification code of the slave unit 30 provided in the air conditioning unit 2 which is stored in advance. The remote control data transmitting means 26 transmits this using radio waves. In the child device 30 included in the air conditioning unit 2, when the operation command is transmitted from the parent device 20 of the air conditioning management device 8 using wireless radio waves, a response signal is sent to the parent device 20.
Is transmitted using radio waves. The master device 20 confirms that the identification code of the transmitted response signal is the identification code for the slave device 30 provided in the air conditioning unit 2, completes the response signal reception, and completes the transmission of the operation command to the air conditioning unit 2. ..

Next, the master unit 20 and the slave unit 30 when the operation is set by the general subscriber telephone set 10 installed elsewhere
The main operation relating to the transmission / reception of the data by the radio waves in FIG. 27 will be described with reference to the flowcharts shown in FIGS. 27 and 28 by taking the case of setting the operation of the air conditioning unit 2 as an example. First, the operation of the master device 20 will be described. When the power of the air conditioning management device 8 is turned on in step 80, that is, when the operation of the parent device 20 is started, the parent device 20 enters the input waiting state in step 81. In the input waiting state of step 81, the user calls the telephone 9 equipped with a wireless transmitter / receiver from the general subscriber telephone set 10 installed in another place, and sends out the operation command to the air conditioning unit 2 designated in advance. , The telephone 9 transmits this operation command using radio waves, and it is judged in step 82 that the remote control data is input, that is, when the remote control data is received, step 8
At 3, remote control data input, that is, the air conditioning unit 2
Is transmitted using a radio wave together with the stored identification code for the child device 30 provided in the air conditioning unit 2. Then, in step 84, a response signal from the slave unit 30 is waited for. When the slave unit 30 of the air conditioning unit 2 receives the operation command, a response signal is transmitted from the slave unit 30 using the radio wave, and when it is determined that the response signal from the slave unit 30 is received in Step 85, Step 86 At, it is determined from the received response signal whether the control information is normally transmitted. If it is determined in step 86 that the control information has been normally transmitted, in step 87 the air conditioning unit 2
To end the transmission of the driving command to. After the transmission of the operation command, the process returns to the input waiting state of step 81. If the response signal from the handset 30 has not been received even after the lapse of a predetermined time in step 85, the error process in step 88 is performed.
After that, the process returns to the input waiting state of step 81. If it is determined in step 86 that the operation command is not normally transmitted from the received response signal,
After performing error processing 02 in step 89, the process returns to the input waiting state of step 81.

Next, the operation of the child device 30 will be described. In step 90, for example, the power of the air conditioning unit 2 is turned on,
That is, when the operation of the child device 30 is started, the child device 30 enters an input waiting state in step 91. In the input waiting state of step 91, the control command, that is, the operation command to the air conditioning unit 2 is transmitted from the base unit 20 using wireless radio waves, and step 92
If it is determined that the driving command is transmitted using the wireless radio wave in step S93, it is determined in step 93 whether the identification code transmitted using the wireless radio wave together with the driving command matches the stored own identification code. .. If the identification codes match, the operation command is received as a command for the own unit in step 94. Then, in step 95, the fact that the operation command has been received is transmitted using a radio wave as a response signal together with the stored own identification code, and the operation command reception ends. After receiving the operation command, the process returns to the input waiting state of step 91. If the identification codes do not match in step 93, the operation command transmitted using the radio wave is treated as invalid data, and the operation returns to the input waiting state in step 91.

According to the invention as described above, the air-conditioning management device does not take in a large-scale device and is not restricted by the place where it is placed. A person who operates the management device can use it without any change from a normal air conditioning management device.

In this embodiment, since the operation command is transmitted from the master unit to the slave unit and the response signal is transmitted from the slave unit to the master unit, the identification code of the master unit is not added and transmitted. It is also possible to add the identification code of the master unit and transmit it to clarify that it is a command transmission from the master unit or a response signal to the master unit. Note that transmission / reception between the master unit, the relay unit, and the slave unit can be similarly performed.

FIG. 32 shows a communication system when the slave unit is not provided with the timer control unit 700 of the present invention, and FIG. 33 is a communication system when the slave unit is provided with the timer control unit 700 of the present invention. In these figures,
(A), (b), and (c) indicate that data is transmitted and received in the data format shown in FIG.

Next, the operation of the centralized control system for an air conditioner configured as above will be described from the transmission operation. When a transmission request is generated, the reception frequency setting unit 139 sets a certain frequency, for example, f1 before the transmission is started, the receiver control unit 141 controls the receiver 137, and the reception state is set at the frequency f1. The presence or absence of radio waves is detected at 142. Here, if the radio wave of the frequency f1 is detected, the reception frequency setting unit 139 resets the frequency to, for example, f2, and the presence or absence of the radio wave is checked again. When the radio wave of the frequency f2 is not detected, the transmission frequency setting unit 133 immediately sets the transmission frequency f2.
Then, the transmitter control unit 135 controls the transmitter 131, and the data generation unit 136 starts transmission of transmission data generated in a predetermined format using a radio wave of frequency f2. Next, the receiving operation will be described. The radio wave detector 142 detects the presence / absence of a radio wave having an arbitrary frequency set in the reception state. If the radio wave is not detected, change the frequency and detect the radio wave again.
The above operation is repeated until the radio wave is detected. Then, when a radio wave of a certain frequency, for example, the frequency f2 is detected, the data received and demodulated by the receiver 137 is received by the data receiving unit 143. Then, it judges from the received data whether or not it is a command for itself. If it is a command for oneself, it will process according to the content. If they are different, the process returns to the receiving state again without processing.

The control method of the centralized control system (FIG. 30) of the air conditioner consisting of the master unit and the slave unit which performs transmission / reception in the above-mentioned procedure will be described by taking the case where the air conditioner 4 is controlled by the air conditioning management device 8 as an example. To do. First, a case where the child device does not have the timer control means 700 of the present invention (FIG. 32) will be described. The parent device 20 provided in the air conditioning management device 8 wirelessly transmits control information for controlling / managing the air conditioning device 4 to the child device 30b using, for example, a radio wave of frequency f5 (741).
a)). The child device 30b determines that the received data is a command for itself, controls the air conditioner 4 according to the content, sends a response signal to the parent device 20, and then waits in the receiving state again. (State of 742a).
On the other hand, the slaves 30a and 30c determine that the command is not for themselves, and wait again in the reception state. Here, when the slave unit 30a tries to start transmission to the master unit 20 at the frequency f5 during communication between the master unit 20 and the slave unit 30b, the slave unit 30a first transmits at the frequency f5 before transmission. The reception state is set, and the radio wave detection unit 142 determines the presence or absence of a radio wave. Since the frequency f5 is being used by the parent device 20 and the child device 30b, after confirming that the frequency is not used, for example, f6, the transmission frequency is switched to f6 and transmission to the parent device 20 is started (743a Condition). However, since the master device 20 is in communication with the slave device 30b, it cannot receive the radio wave from the slave device 30a and does not transmit a response signal to the slave device 30a. Since the response signal is not returned, the child device 30a starts transmission to the parent device 20 again at the frequency f6 (7
43b), the master device 20 cannot receive the signal of the slave device 30a unless communication with the slave device 30b is completed, and the transmission operation is repeated during this period (state of 743c).
Communication becomes possible only after the communication of the base device 20 is completed (74
State 4).

Next, the slave unit is provided with the timer control means 7 of the present invention.
The case where 00 is provided will be described. In FIG. 33,
When the parent device 20 wirelessly transmits control information for controlling and managing the air conditioner 4 to the child device 30b in the same manner as described above, for example, at the frequency f5 (state of 751a), the child device 30b receives the received data by itself. Command, the air conditioner 4 is controlled according to the content of the command, the response signal is transmitted to the master device 20, and then the standby state is resumed in the receiving state (state of 752a). On the other hand, the child device 30a and the child device 3
When determining the data, 0c simultaneously determines whether the received data is a command from the master device 20 in the own system. If it is a command from the master device 20 in the own system (here, a command to the slave device 30b), it can be determined that the master device 20 will be in communication with another slave device (here, the slave device 30b). Here, if the data format used for communication is constant as shown in FIG. 31 and the number of times of communication (command + response) is constant as shown in FIG. Time until the end of communication between machines 30b Ti
Seconds = T1 (or T2) seconds + 2 × T3 seconds can be predicted. Therefore, the slaves 30a and 30c can perform other control during that time by setting the communication time Ti seconds in the timer after receiving the data and stopping the transmission operation to the master 20 until the timer expires. Then, after Ti seconds, the parent device 20 has finished communication with the child device 30b, and therefore, here, the child device 30a (or the child device 30c).
May start transmission to the master device 20 (state of 753).

Example 15. FIG. 34 is a diagram showing a case where the number of times of data communication between the master unit and the slave unit is irregular. Figure 3
In 4, when the number of times of data transmission is irregular due to the control content for the air conditioner, it is difficult to predict the communication time Ti and set it in the timer 700a. However, since the data format at the time of transmission is determined as shown in FIG. 31, the time Tj until the master transmits the control signal to the slave and the slave completes transmitting the response signal to the master.
Is constant such that Tj seconds = T1 (or T2) seconds + T3 seconds. Further, since the initial communication time Tj is set after receiving the transmission data from the master unit, the time Tj seconds = T3 seconds obtained by subtracting T1 (or T2) seconds. Then, this Tj can be set in the timer, and after Tj seconds, the transmission operation to the parent device can be started (state of 764). The slave unit can efficiently detect the communicable state of the master unit by repeating the above operation until the master unit finishes communication and communication becomes possible, and can perform the same control as in the fourteenth embodiment (761, 762).

Example 16. FIG. 35 is a block diagram of a master unit and a slave unit in an embodiment of the sixteenth invention. In FIG. 35, 130 to 145 and 700 are the same as those in the 14th embodiment. A frequency control unit 725 determines a usable frequency and controls the transmission frequency and the reception frequency. FIG. 36 is a block diagram of a centralized control system for an air conditioner according to the present invention. In FIG. 36,
Reference numeral 8 denotes an air conditioning management device that is configured as shown in FIG. 35 and includes a parent device 20 that wirelessly transmits and receives air conditioner control information to and from each child device 781 to 789 provided in each air conditioner.
8A is an air conditioning block including an air conditioning management device 8 and slave units 781 to 789. FIG. 37 shows a timer control means 70
FIG. 7 is a diagram showing a timing of setting an operation time limit for a terminal (master device or slave device) in communication with a corresponding frequency in 0 and the frequency control means 725 in a timer 700a. In FIG. 37, reference numerals 791 to 797 indicate the timings at which the communication time for each frequency is set.

Next, the operation will be described. The transmitting operation and the receiving operation of the parent device and the child device in the present invention are the same as those in the fourteenth embodiment. In FIG. 36, in the air conditioning system in which a plurality of child devices other than the parent device communicate with each other at the same time, the child device 7
A case where 82 communicates with the child device 786 will be described. Each slave unit checks the presence or absence of radio waves for a plurality of frequencies (here, f1 to f16) while not performing the transmission / reception operation, as in the fourteenth embodiment. When a radio wave of a certain frequency is detected by the radio wave detection unit 142, it is determined at the same time whether the radio wave is a frequency used by the parent device and another child device in the own system. Here, when it is found that the frequency is used by the master device 20 or another slave device in the own system, the operation limit time for the terminal (master device or slave device) communicating with the corresponding frequency is set by a timer. Control means 700
Then, the timer 700a is set as the communication time Th. In this way, the above operation is repeated, and when radio waves of a plurality of frequencies are detected, the communication time Th for each frequency and communication terminal is set in the timer 700a (FIG. 37). For example, at the time of 709A in FIG.
It is assumed that a transmission request is issued to the child device 786. At this time, the radio waves of frequencies f1, f2, and f4 have already been used in the own system, and the communication time Th is set in the timer 700a (states 791 to 793). It is also known that the child device 786 is not communicating. Since the slave unit 782 cannot use these frequencies until the timer expires, the slave unit 782 sets the transmission frequency from the remaining frequencies. That is, radio waves are detected for the frequencies f3, f5 to f16, and among them, the frequency at which no radio wave is detected, that is, the frequency that is not used in other systems, for example, the frequency f16 is set as the transmission frequency.
Transmission is started for 6 (state of 797).
