Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a controller for displaying the operation status of each terminal in a hot water heating system.

[0002]

2. Description of the Related Art In a hot water heating system, there is a controller for displaying the operating status of a heat source unit, but there is no controller for displaying the operating status of each terminal (radiator).
For this reason, what operating status each terminal is currently in, for example, whether it is operating or stopped, how many times the set temperature is set, how many times the current room temperature is, the fan is strong / medium / weak , And whether the filter is clogged or the like cannot be monitored by the controller.

[0003]

Therefore, there is a problem that all terminals cannot be centrally managed. Of course, it is possible to monitor all terminals by adopting a control system that is practically used for other terminals for all terminals, but in this case, there are the following problems. a. When the number of terminals increases, it takes time to complete communication with all the terminals, and display is delayed. b. When the amount of information to be communicated increases and communication is performed a plurality of times, it takes time until all information necessary for detailed display is prepared. c. Terminals that require immediateness of display and terminals that do not require the same need to change the communication speed, data configuration, etc. in order to perform communication in a similar manner.

An object of the present invention is to provide a controller capable of centrally monitoring all terminals and monitoring a specific terminal in preference to other terminals in a hot water heating system.

[0005]

The structure of the controller for a hot water heating system according to the present invention is as follows.

[0006] It has a function of displaying a list of all terminals and a detailed display function of each terminal, and in principle, sequentially communicates with each terminal. The display terminal can be designated, and if there is a designated detailed terminal, the designated detailed terminal is configured to perform communication by interrupting the communication sequence between the other terminals. System controller.

[0007]

In the monitoring mode, a list of all terminals is displayed on the display device of the controller. Further, the detailed display is automatically performed at an interval or by selection. When a specific terminal is designated by the selection, the detailed display of the terminal is displayed, and the communication of the terminal is performed at short intervals by interrupting the communication timing of another terminal. For example, No.
If there is a terminal from No. 1 to No. 10, if the detail display is selected for No. 2, the normal communication timing will be 1
→ 2 → 3 → 4 → 5 → 6 → 7 → 8 → 9 → 10 → 1 ... For example, 1 → 2 → 3 → 4 → 2 → 5 → 6 → 2 → 7 → 8 →
2 → 9 → 10 → 2 → 1 → 2 ...

FIG. 1 shows an embodiment of the present invention. 1, 2, 3-
10 is a terminal, 11 is a communication terminal selection device, 12 is a controller control device, 13 is a priority terminal determination device, 14 is a display device,
The following control is performed. The display form includes a list display and a detailed display. In the list display, representative information of each of the terminals 1 to 10 is displayed on the display device 14 in a list. In principle, detailed display is to display 1 to 10 terminals in order.If there is a terminal that you want to monitor or want to enhance monitoring among these terminals, select this and enter the terminal number. Then, the detailed display of the terminal is performed, and the communication with the terminal is performed by interrupting the communication timing of another terminal. This is controlled by the priority terminal determination device. The interrupt may be every other or every two, and the interrupt timing may be set in advance, or may be set each time.
If data is changed during communication with each terminal, the data of the controller is rewritten each time.

The flow of communication timing in the above embodiment is as follows.

[0010] Normal communication timing ・ When detailed display is specified for terminal 2

As described above, according to the present invention, when the detailed display of a specific terminal is specified, the communication of this terminal is performed by interrupting the communication timing of another terminal. As a result, the following effects are obtained. a. Even if the number of connected terminals increases, there is no delay in displaying the status of the terminal displayed in detail. b. Even if the data volume increases and communication is performed multiple times,
The time required to communicate all the data necessary for the detailed display can be reduced. c. Immediateness of communication with a terminal that is performing detailed display can be improved without changing the communication transmission speed or the like.
