Description

[Detailed description of the invention] <Industrial application field> This invention relates to a wiring check device in an air conditioning system, and more specifically, it has a plurality of outdoor units and at least one device for each outdoor unit. The present invention relates to a device for checking whether wiring between a central monitoring device and an outdoor unit is properly conducted in an air conditioning system to which an indoor unit is connected.

<Prior art and problems to be solved by the invention> Traditionally, in high-rise buildings, etc., multiple outdoor units are installed, and at least one indoor unit is connected to one outdoor unit. An air conditioning system is used that connects each room to condition the air in each room.

In such an air conditioning system, a control device (hereinafter referred to as a remote control) is used to set the operating state of the indoor unit in order to perform air conditioning in each room regardless of the conditions in other rooms. However, by transmitting data between each indoor unit and the outdoor unit, the status of each indoor unit whose address has been set in advance can be grasped, and the status of each indoor unit can be determined. The outdoor unit is made to operate in a state that corresponds to the situation.

A central monitoring device is installed in a part of the high-rise building, and the central monitoring device is provided with a display for displaying the operating status of each indoor unit.

By the way, in the case of a high-rise building, the number of wiring between the above-mentioned central monitoring device and the outdoor unit becomes very large and the length becomes long, so when the installation work is completed, one of the wiring
It is nearly impossible to check whether the wiring is correct for each book, and in reality, while at least one person is monitoring the central monitoring device, another person is installing it in each room. The indoor unit is started and stopped by operating the remote controller, and the outdoor unit set in the central monitoring device is connected to the actually operated indoor unit using an extension telephone, etc. It is determined whether the installed outdoor units match or not, that is, whether or not the wiring for each outdoor unit is properly performed.

Therefore, there is a problem in that a large number of workers are required to determine whether or not the wiring to the outdoor unit is properly performed.

Furthermore, if there is only one person checking the wiring, it is necessary to perform the above-described determination work while frequently going back and forth between each room and the central monitoring device.

Therefore, in this case, there is a problem that the time required to check the wiring becomes extremely long. In particular, since the above-mentioned centralized monitoring equipment is usually installed in the basement or top floor of a high-rise building, it must be shuttled between the basement or top floor and each room. As a result, the above-mentioned problems become more prominent.

<Purpose of the invention> This invention was made in view of the above problems, and allows one worker to check whether the wiring to all outdoor units is properly done in a relatively short period of time. The purpose of the present invention is to provide a wiring check device that can perform a wiring check.

<Means for solving the problem> In order to achieve the above object, the wiring check device of this invention collects information indicating at least the operation start order of the outdoor unit whose operation is controlled based on the operation on the indoor unit side. The system is equipped with centralized monitoring means for collecting and retaining information, and output means for outputting at least information indicating the operation start order.

However, the centralized monitoring means may also monitor the operation start time and operation stop time of each indoor unit.

Furthermore, the output means may be a printer.

<Function> With the wiring checking device configured as described above, in an air conditioning system having a plurality of outdoor units, with at least one indoor unit connected to each outdoor unit, the centralized monitoring means can collect and retain information indicating at least the start-up sequence of each outdoor unit, and the information indicating at least the start-up sequence can be output by the output means.

Therefore, by one worker operating the indoor units installed in each room in sequence, the centralized monitoring means can monitor the status of the outdoor units that are operated in accordance with the indoor units that are being operated in sequence. is monitored and outputted by the output means, so after performing operations on at least one indoor unit corresponding to each outdoor unit, by comparing the order of operations by the worker and the output results from the output means, It is possible to check whether the wiring to each outdoor unit is properly performed.

When the centralized monitoring means also monitors the operation start time and operation stop time of each indoor unit, it stores the operation start order or operation stop order of each indoor unit, or By making a memo, it is possible to check whether the wiring to each outdoor unit is properly performed or not simply by comparing the results with the output results from the output means.

Further, when the output means is a printer, it is possible to check whether the wiring to each outdoor unit is properly performed or not simply by comparing the output results with the printed output results.

<Examples> Hereinafter, examples will be described in detail with reference to the accompanying drawings showing examples.

FIG. 3 is a schematic diagram showing an embodiment of an air conditioning system incorporating the wiring check device of this invention, in which a plurality of outdoor units 21, 22, . , a plurality of indoor units 41, 42...4m connected in parallel to each outdoor unit via refrigerant piping, and each of the outdoor units 2
Terminal board 3 provided on each of 1, 22...2n
1, 32...3n, and each of the above indoor units 41, 42...4
Remote controllers 51, 52...5 connected to m
m, the integrated power meter 1, and the terminal board 31,
32...3n, and an output section 7 connected to the centralized monitoring device 6.

It should be noted that since the indoor unit is connected to the outdoor unit in series, there are almost no wiring errors.

More specifically, between the remote controller and the indoor unit, control data from the remote controller is transmitted to the indoor unit, and the operation of the indoor unit is controlled based on the control data.

In addition, between the above indoor unit and outdoor unit,
Control data, status data, etc. are mutually transmitted through a data transmission line (not shown) connected to the terminal board, and the operations of both are controlled to perform air conditioning operations corresponding to the set status. .

Furthermore, control data, status data, etc. are transmitted from the outdoor unit to the centralized monitoring device 6 through a data transmission line (not shown) connected to the terminal board of the outdoor unit. .

Note that data transmission lines connecting the outdoor unit and the central monitoring device 6 are provided between the central monitoring device 6 and the outdoor unit, and as the number of outdoor units increases, the number of data transmission lines increases. The number of books increases.

Furthermore, in the centralized monitoring device 6, the operating state data of the indoor units is taken in through the terminal board provided in the outdoor unit, and the cumulative operating time of each indoor unit is calculated based on the operation start time and operation stop time. , the integrated power data from the integrated power meter 1 is taken in to calculate the integrated power for each indoor unit.

In addition, the output unit 7 prints out the operation start time and operation stop time of each indoor unit from among the monitoring data in the central monitoring device 6, together with the identification symbol of the corresponding indoor unit. .

FIG. 1 is a schematic block diagram illustrating the central monitoring device 6 in detail, and shows the terminal boards 31, 32, . . .
3n is connected via data transmission lines 81, 82, . , an identification unit that uses the data received by the receiving unit 63 as input to identify the operating state, the fact that the operating state has been switched, the type of operation (for example, heating operation or cooling operation, etc.), the type of abnormal state, etc. 64, a clock 65, and a memory write control section 67 that inputs the identification data from the identification section 64 and the time signal from the clock 65 and writes the operation start time, operation stop time, etc. in the corresponding area of the memory 66; A memory read control unit 68 that reads out the written contents of a designated area of the memory 66, and a control unit that supplies necessary transmission data to the transmission unit 62 and generates a state determination signal by inputting the identification data from the identification unit 64. 69.

Further, the control section 69 transmits data read out from the memory 66 by the memory read control section 68 to the output section 7 as data to be printed out. Furthermore, the integrated power data from the integrated power meter 1 is also input to calculate the integrated power for each indoor unit.

The operation of the air conditioning system having the above configuration is as follows.

Data is exchanged between the outdoor unit and the indoor unit through the data transmission line, and data is also exchanged between the central monitoring device 6 and the outdoor unit through the data transmission line. . Therefore, a signal indicating whether each indoor unit is in an operating state or a stopped state is supplied to the identification section 64 through the selector 61 and the receiving section 63, and the operating state or stopped state is continued. It is determined whether the vehicle is in operation, in operation, or stopped.

If it is determined that the operating state is continued, the indoor unit is switched to the relevant indoor unit based on the integrated power signal from the integrated wattmeter 1, taking into consideration which other indoor units are in the operating state. Accumulate the corresponding power.
In addition, if it is identified that the vehicle is in a driving state,
The memory write control section 67 writes data indicating that the operation has started into the memory 66 together with the time signal at that point, and conversely, when it is determined that the operation has stopped, the memory write control section 67 writes the data indicating that the operation has started. Data indicating that the operation has been stopped is written in the memory 66 together with the time signal at that point.

Thereafter, at a predetermined timing, the memory read control unit 6 under the control of the control unit 69
8 reads out the time signal and the unique identification signal of the indoor unit along with the signal indicating the operating state or the stopped state, and supplies them to the output section 7 . Therefore, the output unit 7 outputs the unique identification symbol, time, and start of operation corresponding to each indoor unit.
Alternatively, the distinction between operation and stoppages can be printed out.

In addition, if you want to check whether the wiring has been done correctly when an air conditioning system is first installed, go to the room where each indoor unit is installed and operate the indoor units one by one by operating the remote control. All you have to do is start or stop it, and the memory 6
In the area corresponding to each indoor unit 6, a signal indicating the start or stop of operation and a signal indicating the time are written. Therefore, after completing the above series of operations, go to the location where the output unit 7 is installed and check the unique identification symbol corresponding to each indoor unit, as well as the distinction between operation start and operation stop, and the time. By printing out the information, it is possible to easily determine whether or not the start or stop of operation is recorded in the order of the indoor units that were actually started or stopped.

If the actual order of all indoor units matches the recorded order, then the wiring has been done correctly, and conversely, the actual order and the recorded order match. If not, it means that the wiring has not been done correctly, and the wiring can be easily checked. Moreover, even if the wiring is not done correctly, indoor units that require accurate wiring can be easily recognized as indoor units whose actual order and recorded order do not match. .

Note that this invention is not limited to the above-mentioned embodiments; for example, a handheld computer can be used as the output section 7, and a clock provided in the handheld computer can be used as a clock for displaying the time. Furthermore, it is possible to omit the time display and simply output the order of the indoor units, and various other design changes can be made without changing the gist of this invention. It is possible to apply

<Effects of the Invention> As described above, the invention collects and stores information indicating at least the operation start sequence of each outdoor unit, and outputs it collectively, so that an operator can operate the equipment in one
This provides a unique practical effect in that even a person can easily check in a comparatively short time whether the wiring to each outdoor unit has been performed correctly.
