I did it. [Effect] The operation data and the like can be collected from a remote location easily and in real time, and the failure diagnosis can be performed accurately and in a short time.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an interface device which is connected to a device such as an air conditioner and used to collect operation data necessary for failure diagnosis.

[0002]

2. Description of the Related Art In a conventional device, as shown in Japanese Patent Laid-Open No. 5-11835, data necessary for failure diagnosis is collected by connecting a device to be diagnosed with a dedicated line and analyzing the data. .

[0003]

However, in the conventional device, it is necessary to connect a device for failure diagnosis and a device used for collecting operation data with a dedicated line.
The transmission destination of operating data was limited. In addition, even when a wired telephone line is used for data transmission, a dedicated telephone line must be separately drawn at the place where the device to be diagnosed is installed, which requires a large capital investment.

Further, normally, it is not necessary to collect operation data for failure diagnosis and a dedicated line is not drawn. For this reason, there was a problem that a data collection device had to be brought near the equipment and installed. Furthermore, in this case, since the data is once collected and then analyzed, there is a problem that it takes time for failure diagnosis.

[0005]

In order to solve the above problems, in the present invention, the interface device used for collecting operation data is provided with a telephone terminal function which can be connected to a mobile telephone or a wireless telephone line.

Further, the interface device used for collecting the operation data is provided with a modem function capable of connecting to a mobile phone or a telephone terminal of a wireless telephone line.

Further, in addition to the above functions, the interface device used for collecting operation data is provided with a function of receiving a driving signal from an external device through a portable or wireless telephone line and issuing a driving command to each device.

[0008]

As described above, it becomes possible to easily and in real time transmit the operation data of the device to a plurality of distant destinations through a mobile phone or a wireless telephone line.

[0009]

Embodiments of the present invention will be described below with reference to FIGS.

FIG. 1 is a block diagram of the system of the first embodiment, and FIG. 2 is a block diagram of the system of the second embodiment.

(First Embodiment) The equipments 1 and 2 to be collected operation data have a control device 3 inside the equipments to obtain operation data of the equipments from a plurality of detectors 4 and perform operation control of the equipments. There is. Further, the interface device 5 is connected to the control device 3 of these devices and collects operation data of each device. In the present embodiment, the interface device 5 has a telephone terminal function of a mobile or wireless telephone line, and by calling the interface device 5 from the telephone terminal 6, the portable or wireless telephone line 8 is connected and the device 1 It is possible to collect the operation data of the device 2 and the device 2 in the failure analysis device 7 through the mobile phone or the wireless telephone line 8 and perform the failure analysis and the data collection for preventive maintenance.

(Second Embodiment) For the devices 1 and 2 to be collected operation data, the operation data of each device is collected using the interface device 9 as in the second embodiment. In the present embodiment, the interface device 9 has a modem function capable of connecting to a mobile phone or a telephone terminal of a wireless telephone line, and the telephone terminal 10 of a wireless telephone line is connected to the interface device 9 to provide a telephone terminal. 6 to call a telephone terminal 10 to connect a mobile or wireless telephone line 8, and to collect operation data of the device 1 and device 2 through the interface device 9 and the failure analysis device 7
To collect data for failure analysis and preventive maintenance.

(Third Embodiment) In this embodiment, in the system configuration of the first embodiment or the second embodiment, the test operation for failure analysis is carried out by the failure analysis device 7 by the portable or wireless telephone line 8 and the interface device. For more advanced failure analysis and preventive maintenance by instructing each device via 9 and collecting the operation data at the time of test operation in the failure analysis device 7 using the mobile phone or the wireless telephone line 8 again. It is possible to collect the data.

[0014]

According to the present invention, the operation data can be transmitted to a distant place without collecting a dedicated line or a dedicated telephone line for data transmission in order to collect the operation data of the device to be diagnosed. It will be possible. Further, even when operation data needs to be collected in the short term due to equipment failure or the like, the operation data can be transmitted to a plurality of distant destinations simply by installing the interface device near the equipment. Further, as a result, a device manufacturer or a service company can obtain and monitor required data directly and in real time from a distance, and can monitor the data accurately and in a short time.
