Embodiment Construction

[0026] Embodiments of the present invention will be described in detail with reference to the drawings.

[0027] figure 1 It is a figure which shows the structure of the equipment management system 1 which concerns on embodiment of this invention. The equipment management system 1 is a system for managing air conditioners as an example of equipment equipment. Such as figure 1 As shown, the equipment management system 1 includes an outdoor unit 110, indoor units 120a, 120b, remote controllers 130a, 130b, and an equipment management device 200 as a plurality of equipment. In addition, the outdoor unit 110 , the indoor units 120 a , 120 b , the remote controllers 130 a , 130 b , and the equipment management device 200 are connected to each other by a communication line 140 so as to be capable of data communication. In addition, in figure 1 In the figure, one outdoor unit 110, two indoor units 120a, 120b, and two remote controllers 130a, 130b are illustrated as a plurality of ...

Abstract

A facility management device (200) manages communication data sent and received between remote controllers (130a, 130b) and an external unit (110 and / or internal units (120a, 120b). A temporary-storage controller (421) stores for a prescribed time in a temporary storage unit (310), communication data received by a communication unit (210), and transmission-waveform data acquired by a transmission-waveform-data acquisition unit (220). An abnormality determination unit (424) determines whether an abnormality is present in the communication data stored in the temporary storage unit (310). When it is determined that an abnormality is present in the communication data stored in the temporary storage unit (310), a data copying unit (425) stores all of the data stored in the temporary storage unit (310) in an abnormal-data storage unit (330).

Description

technical field [0001] The present invention relates to an equipment management device, an equipment management system, an equipment management method, and a program for managing communication data transmitted and received between a plurality of equipment devices. Background technique [0002] Among the communication abnormalities in the communication system used for the control of equipment such as air-conditioning equipment and lighting equipment, there are communication abnormalities at the physical layer level in which the shape of the transmission waveform flowing through the transmission path is disturbed due to some factors. Therefore, the content of the signal generated by the transmission source terminal cannot be maintained until it reaches the transmission destination terminal. In order to identify the cause of such a communication abnormality at the physical layer level and restore the communication system, it is desirable to be able to acquire and analyze the tr...
