In addition, since there is a means for comparing the system information registered and set in the field with the actual system information at the present time and reporting the result of the comparison to the remote monitoring terminals 11A to 11C, it cannot be found at the time of the field adjustment. Address setting errors and the like can be confirmed from a remote location without having to go to the site, and a remote control system with excellent local adjustment and serviceability is provided.

Embodiment 2 of the Invention FIG. 5 is a block diagram showing a main configuration of an equipment controller according to Embodiment 2 of the present invention. The illustrated equipment controller 5 includes remote monitoring terminals 11 </ b> A to 11 </ b> A in addition to the configuration shown in the first embodiment.
Address information rewriting means 21e for rewriting the address information of the internal system information storage means 21a based on a command from 11C, and the contents set by the on-site adjustment means 24 to the contents automatically detected by the system information collecting means 21c. The microcomputer 21 is provided with a rewriting execution determining means 21f for determining whether or not to rewrite and setting the rewriting timing.

Next, the processing procedure in the second embodiment will be described with reference to the flowchart of FIG. The equipment controller 5 sets the actual address information of the air conditioners 30A to 30C automatically collected by the system information collection means 21c from the local adjustment means 24 by a local worker to perform grouping for performing group control and the like. If the address information is different from the registered address information (S21), the address information is set according to the condition set in the rewriting execution determining means 21f (S2).
2) The contents registered and set by the local adjustment unit 24 are rewritten to the contents automatically collected by the system information collection unit 21c. Then, the rewriting execution determining means 21f first checks whether or not a setting is made to send a report to the remote monitoring terminals 11A to 11C (S23), and if the setting is made to send a report (S23). (Y), a notification is sent to the remote monitoring terminals 11A to 11C via the public line communication means 23 (S24). Next, it is confirmed whether or not the setting of the rewriting execution determining means 21f is set to automatically rewrite the information of the system information storing means 21a (S2).
5) If the automatic rewrite setting is set (Y), the address information registered in the system information storage means 21a is rewritten to the contents collected by the system information collection means 21c (S26). In addition, remote monitoring terminals 11A to
If the system information is set to be updated after waiting for a command from the remote monitoring terminal 11C (Y in S25), the system waits for a command from the remote monitoring terminals 11A to 11C (S27). When receiving commands from the remote monitoring terminals 11A to 11C (S27)
(Y), the address information in the system information collecting means 21a is rewritten to the contents automatically collected by the system information collecting means 21c by itself (S26). Naturally, the waiting time of the command from the remote monitoring terminal 11 is set, and if no command is received during the set waiting time (timeout Y), the operation is performed with the current information.

As described above, since the remote control system of this embodiment has means for automatically changing and rewriting system information registered and set on site, there has been a system setting error. Even in such a case, the setting can be changed from a remote place without having to go to the site.
In addition, since rewriting can be performed after confirmation by the remote monitoring terminals 11A to 11C, detailed information such as a local setting error can be confirmed, and the reliability of the system is maintained.

Embodiment 3 of the Invention FIG. 7 shows the third embodiment.
FIG. 2 is a block diagram showing a main configuration of the equipment controller in FIG. Instead of the address information comparing means 21d in the second embodiment, the equipment controller 5 automatically detects the group information registered and set on site by the on-site adjusting means 24 and the actual information automatically detected by the system information collecting means 21c. Instead of group information comparing means 21g for comparing with group information and address information rewriting means 21e,
The microcomputer 21 includes a group information rewriting means 21h for executing rewriting of group information in the system information storage means 21a based on a command from the remote monitoring terminals 11A to 11C.

Next, the operation of the equipment controller 5 according to the third embodiment will be described with reference to FIGS. FIGS. 8 and 9 show the flow of comparison, reporting, and rewriting of group information. First, the flow of FIG. 8 will be described. When the system information including the group information of the air conditioners 30A to 30C is set by the local adjustment unit 24, the equipment controller 5 writes the system information in the system information storage unit 21a and registers the system information (S31). After the writing is completed, the system information collecting means 2
1c, system information such as group information in the local air conditioning system 31 is automatically collected (S32), and group data of the air conditioners 30A to 30C registered in the system information storage unit 21a and system information collection unit Air conditioning system 31 automatically collected at 21c
Is compared by the group information comparing means 21g (S33). As a result of the comparison, if there is a difference between the group data in the system information storage unit 21a and the group data automatically collected (Y), it is notified that there is a difference between the remote monitoring terminals 11A to 11C via the public line communication unit 23. A notification is issued (S34). Remote monitoring terminals 11A to 11C that have received a difference in group information of air conditioning system 31
Displays this on the screen and informs the administrator.

The system information is searched for after the contents set by the on-site adjustment unit 24 are written in the system information storage unit 21a. However, as in the first embodiment, the remote monitoring terminal 11A is searched. 11C may be executed in a timely manner, or an input of the search command means 26 from a local worker may be used as a trigger. As described above, when the input operation of the local worker from the search command unit 26 is triggered, the remote monitoring terminals 11A to 11A to
There is no need to notify 11C, and only that may be displayed on the display means 25. Further, similarly to the first embodiment, the system information collection means 2 of the equipment controller 5 itself according to a command from the remote monitoring terminals 11A to 11C.
The contents automatically collected in 1c and the contents registered and set by the local adjustment means 24 are stored in the remote monitoring terminals 11A to 11C.
It is also possible to send to.

Next, the flow of FIG. 9 will be described. When the group information of the air conditioning system 31 automatically collected by the system information collecting unit 21c differs from the group information set and registered by the local worker from the local adjustment unit 24 (S41), the equipment controller 5 determines whether the rewriting is performed. 21f in accordance with the conditions set in 21f.
Overwrites the contents registered and set by the user with the contents automatically collected by the system information collecting means 21c. And
The rewriting execution determining means 21f firstly checks the remote monitoring terminal 11A.
It is confirmed whether or not the notification is set to report to the remote monitoring terminals 11A to 11C (S43). The notification is made via the Internet (S44). Next, it is confirmed whether or not the setting of the rewriting execution determining means 21f is set to automatically rewrite the information in the system information storage means 21a. If the setting is automatic rewriting (Y in S45). , Group information rewriting means 21h
Rewrites the group information registered in the system information storage unit 21a with the contents collected by the system information collection unit 21c (S46). If the system information is set to be updated after waiting for a command from the remote monitoring terminals 11A to 11C (N in S45), the system waits for a command from the remote monitoring terminals 11A to 11C (S47).
Upon receiving the command from the remote monitoring terminals 11A to 11C (Y in S47), the group information rewriting unit 21h rewrites the group information in the system information storage unit 21a to the content collected by the system information collection unit 21c by itself. (S46). Naturally, since the waiting time of the command from the remote monitoring terminals 11A to 11C is set, if the command is not received during the set waiting time (timeout Y), the operation is performed with the current information.

As described above, the remote control system according to this embodiment can automatically collect local group information and transmit it to the remote monitoring terminals 11A to 11C. It is possible to check the group information of the air conditioning system 31. In addition, there is a means for comparing the group information set and registered at the site with the actual group information of the air conditioning system 31 at the present time and reporting the comparison result to the remote monitoring terminals 11A to 11C. Even group setting mistakes that could not be found at times can be confirmed from a remote location without having to go to the site. Further, the group information set in the equipment controller 5 can be rewritten as necessary, and a remote control system excellent in local adjustment and serviceability is provided.

Embodiment 4 of the Invention FIG. 10 is a block diagram showing a main configuration of an equipment controller according to Embodiment 4 of the present invention. The illustrated equipment controller 5 includes, in addition to the configuration described in the third embodiment, a state change detection unit 21i that detects a change in an operation state such as an operation stop, an operation mode, and a set temperature of an indoor unit, and detects the state change. A state change storage unit 21j that stores and retains the history, and a difference between the group information registered by itself and the actual group information of the air conditioning system 31 by the local adjustment unit 24 is predicted from the state change history and registered therein. The microcomputer 21 is provided with a prediction determining unit 21k for determining whether the group information obtained differs from the actual group information of the air conditioning system 31.

Next, a processing procedure of the equipment controller 5 according to the fourth embodiment will be described with reference to FIG. For example, the indoor unit under the group control is controlled by the remote controller 3A in FIG. 1 that controls itself when the operation state of the indoor unit changes when the operation state of the indoor unit changes from operation to stop.
3C, the centralized control device 4 and the equipment controller 5 are notified. Here, as the group information registered in the equipment controller 5, for example, the indoor units 1A to 1C are group 1
Suppose that the indoor units 1D and 1F belong to group 2G. However, in the actual air conditioning system 31, the indoor units 1A and 1B belong to the group 1G, the indoor units 1C and 1D belong to the group 2G, and the indoor units 1E and 1F
Belong to group 3G, remote controllers 3A to 3C
Alternatively, even if the operation state of the indoor unit of the group 1G is switched from operation to stop by the central control device 4, the state of the indoor unit 1C, which should be naturally switched, does not stop.
Next, when the indoor units of the group 2G are stopped, the indoor units 1C and 1D are stopped together, and when the indoor unit 1D is stopped, the indoor units 1E and 1F to be stopped naturally remain operating. The prediction discrimination means 21k predicts and discriminates the difference between the group information from the group information inside the self and the actual operation state of the indoor unit.

That is, the specific operation of the equipment controller 5 is as follows. When the state of the indoor unit changes, the equipment controller 5 detects the content by the state change detecting means 21i (S51) and stores the detected content in the state change storing means 21j (S52). After that, the prediction discriminating unit 31k compares the group information registered in itself with the group information predicted from the actual state change history of the indoor unit (S53), and if no match is obtained (N),
It is determined that there is a setting error in the group information (S54), and the remote monitoring terminals 11A to 11C are notified (S55).

At this time, as described above, the matching of the group information may be performed based on the group information and the indoor units that have been started and stopped, or may be performed including the set temperature. If batch operation / stop is performed and it is not possible to judge the presence or absence of matching only from the operation / stop of the indoor unit triggered by the operation from the remote controller or the central control device, the equipment controller 5 The consistency may be confirmed by spontaneously performing the mode change or the set temperature change from the step (b). However, in that case, it is necessary to always return to the original setting state. Further, as described in the fourth embodiment, when there is a mismatch between the group information registered therein and the actual group information, the on-site adjustment is performed using the same flow as that in FIG. 9 in the third embodiment. The group information registered by the means 24 is transferred to the system information collecting means 21c.
Needless to say, the contents can be rewritten to the contents collected in.

As described above, the remote control system according to this embodiment can match the group information of the on-site registration with the group information of the self-detection based on the change in the operation state of the indoor unit. Therefore, even if there is an incomprehensible group information setting error that is not visible as a communication abnormality such as an address setting error, it can be confirmed from a remote location without conducting a local investigation.

Embodiment 5 of the Invention FIG. 12 is a block diagram showing a main configuration of an equipment controller according to Embodiment 5 of the present invention. The illustrated equipment controller 5 has an air conditioner 30A in addition to the configuration shown in the third and fourth embodiments.

Next, the operation of the equipment controller 5 will be described with reference to FIG. In the equipment controller 5 of the fifth embodiment, the method of confirming the consistency between the group information registered in the equipment controller 5 and the current group information in the air conditioning system 31 is the same as in the third and fourth embodiments, and a description thereof will be omitted. . Then, when the equipment controller 5 detects the inconsistency of the group information (S61), the display unit 25
Or remote monitoring terminals 11A to 11C
(S62), the contents of the mismatch are notified to the serviceman or the administrator. After that, the operation of the group rewriting setting executing means 27 or the remote monitoring terminals 11A to 11A to
Upon receiving the rewrite command from 11C (S63), the group rewrite setting unit 211 makes the air conditioners 30A to 30C,
The previous group information held by the remote controllers 3A to 3C and the central control device 4 is rewritten from the contents set by the local adjustment unit 24 and stored in the system information storage unit 21a (S64). Thereby, consistency of the group information relating to the air conditioning system 31 including the self can be obtained.

The group information receiving means 21m receives group information from the remote monitoring terminals 11A to 11C, and rewrites the contents of the system information storage means 21a at that time with the received group information. The same operation as when the system information including the group information is registered by the on-site adjustment means 24 as in 3 and 4 can also be performed. In addition, the group information of the air conditioners 30A to 30C, the remote controllers 3A to 3C, and the central control device 4 is rewritten to the contents received from the remote monitoring terminals 11A to 11C by the group information receiving means 21m in accordance with the flow of FIG. Needless to say, this is possible.
