BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote monitoring device for remotely monitoring the operational status of equipment in a building.

0002

[Prior Art] For example, Japanese Patent Application Laid-open No. 121551/1983 discloses that a terminal device that detects the operation of equipment in a building and a central monitoring device that centrally monitors equipment in multiple buildings are connected via a communication line. Disclosed are remote monitoring devices configured to be interconnected. In the conventional remote monitoring device according to this disclosure, a sensor is attached to equipment such as air conditioning equipment and elevators installed in a building, and based on the output signal of this sensor, a terminal device can detect the occurrence of an abnormality in the equipment. An operational data signal containing operational data such as abnormality recovery is sent to the central monitoring device via a communication line, and the central monitoring device centrally monitors equipment in multiple buildings using this operational data signal. .

In this type of remote monitoring device, equipment in a plurality of buildings is centrally monitored based on operational data signals transmitted from terminal devices to a central monitoring device, and the central monitoring device monitors the operational data signals received by the central monitoring device. The data is written to the memory of the central monitoring device as historical data. In this case, the remote monitoring device is generally equipped with multiple central monitoring devices, and the operational data signals received by the multiple central monitoring devices are managed by a host computer, and various actions are taken based on the operational data signals. The processed operation data signal data is organized and stored as history data.

FIG. 2 is an explanatory diagram of the reception and management of operational data signals transmitted from the terminal device of a conventional remote monitoring device by the central monitoring device. The operating data signal from the terminal device 3 is transmitted to the central monitoring device 2, and the operating data signal received by the central monitoring device 2 is transmitted to the host computer 1.
will be transferred to, managed and organized. In the figure, terminal device B
, a case is shown in which three types of operation data signals including three types of operation data (a), (b), and (-a) are transmitted to the central monitoring device 2, where operation data (a) (b) ) is the operation data based on the abnormal signal from the sensor connected to the terminal device B, and the operation data (-a) is the operation data (
In contrast to a), this is operation data based on an abnormality recovery signal issued from the center.

[0005] When an operation data signal including such operation data is transmitted from a terminal device, the host computer 1 transmits the operation data (
Assuming that the operation data signal containing a), the operation data signal containing operation data (b), and the operation data signal containing operation data (-a) are transmitted from the terminal device in this order, organize the operation data included in these. do. The organized operation data is then written into the memory as history data.

[0006]

[Problems to be Solved by the Invention] In the conventional remote monitoring device described above, for example, an operation data signal including operation data (b) based on an abnormal signal from a sensor is transmitted normally from terminal device B. Regardless, if a situation occurs where the central monitoring device 2 cannot receive the data normally and processes it, the central monitoring device 2 receives the operational data signal including the operational data (a) and the operational data (-a). The operation data is arranged in the order of the operation data signals including the operation data signals transmitted from the terminal device B. When the operational data is organized in this manner, the occurrence of operational data signals including the operational data (b) based on the abnormal signal from the sensor is no longer left as history data.

Furthermore, in the conventional remote monitoring device, in order for the host computer 1 to manage and organize the data of the operation data signals received by the plurality of central monitoring devices, for example, as shown in FIG. When handling the operation data of the operation data signal, the date data of the occurrence of a factor included in the operation data is analyzed and extracted, and the data is organized in the order of this date data. However, since this type of remote monitoring device handles a huge amount of operational data, the process for analyzing and extracting the date data becomes complicated and requires a considerable amount of time. The present invention was made in view of the current state of this type of remote monitoring device as described above, and its purpose is to collect operational data that is transmitted from a terminal device but not normally received by the central monitoring device. It is an object of the present invention to provide a remote monitoring device that can easily detect the omission of signal operation data from historical data.

[0008]

[Means for Solving the Problems] The above object is such that a terminal device detects the operation of equipment installed in a building, and transmits an operation data signal of the equipment to a central monitoring device via a communication line. In a remote monitoring device that centrally monitors the operation of the facility equipment based on the operation data signal received by the central monitoring device, order data indicating a transmission order is added to the operation data signal transmitted from the terminal device. This is achieved by providing the terminal device with an order data addition means for adding order data.

[0009]

[Operation] With this structure, order data indicating the transmission order is added to the operation data signal transmitted from the terminal device by the order data addition means in addition to the operation data. Therefore, missing operational data signals that were transmitted from the terminal device but not received by the central monitoring device may occur, for example, when the host computer manages and organizes the operational data signals received by the central monitoring device. It can be detected easily and accurately by the occurrence of omissions in the sequential order of order data.
