側駆動電源開閉用接点である。 That is, in FIG. 1, reference numeral 1 denotes an outdoor control device, which is connected to an indoor control device 3 via a transmission line 2. In FIG. 4 is a grounding line for the signal system. 5 is a compressor, 6
is an outdoor blower, and power lines 8 and 9 from power source 7
are connected to each other via normally open contacts 5a and 6a of an electromagnetic switch. The normally open contacts 5a and 6a are driven by a switch (not shown) of the outdoor control device 1. Reference numeral 10 denotes an indoor blower, which is connected to power lines 8 and 9 through a normally open contact 10a of an electromagnetic switch driven by the indoor control device 3. Note that 11 is a contact for opening and closing the outdoor drive power supply, which is controlled by the indoor control device 3.

命により室外制御装置１により制御されるもので
ある。 That is, a signal from the indoor control device 3, for example, a signal indicating that the compressor is ON, is sent to the outdoor control device 1 via the transmission line 2, and after the outdoor control device 1 decodes the signal, a predetermined operation is performed. Similarly, the outdoor blower 6 is also controlled by the outdoor control device 1 based on instructions from the indoor control device 3.

圧縮機５の保護のため、電磁開閉器の常開接点５
ａを開いていた。 As described above, the distributed processing type operation control device normally controls the air conditioner in a master-slave configuration, but in the event of an abnormality, such as when the compressor 5 is locked, a large current may flow through the power line 9. When this is detected by the current transformer 12, the outdoor control device 1 closes the normally open contact 5 of the electromagnetic switch to protect the compressor 5.
A was open.
このように、従来の分散処理形運転制御装置で

していた。 However, in such a conventional system, even if the outdoor side is completely inoperable, the indoor side is not aware of this and maintains the operating condition as if it were normal, so the outdoor unit connects the power line 8, 9
Since the power source 7 is connected to the power source 7 via the power source 7, it has the drawback that it is dangerous for the protection of equipment and for people.

This is a transmission request signal t 1 , and after the request signal, the indoor control device 3 transmits a signal t 2 to the transmission line 2 between 4T and 7T shown on the time axis. This signal t2 is a 3-bit signal, and is used to transmit eight combinations, ie, the status of the compressor 5, the status of the blower, etc. from the indoor side to the outdoor side. Here, the signal from 2T to 3T shown on the time axis is the operable/unoperable signal t3 transmitted from the outdoor side to the indoor side, and in this example, the former is
Hi, the latter is Lo. As shown in Fig. 2, the waveform on the transmission line 2 is a combination of the transmitted waveforms from the indoor side and the outdoor side, but the transmission between the two is based on the time axis starting from the transmission request signal. Because this is done, misrecognition and out-of-synchronization do not occur.
