DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a centralized control device for showcases and the like for collectively managing the operating states of a plurality of showcases and the like.

2. Description of the Related Art In a store such as a supermarket or a convenience store, or in a food processing factory, a plurality of showcases, a refrigerator / freezer, a cooling unit, etc. are installed. It is the present condition that it is individually controlled by the control apparatus which comprises a timer for defrosting and defrosting. Therefore, various setting operations such as the temperature of the showcase and the like and the defrosting time must be individually performed at the place where the showcase and the like are installed. Therefore, when the setting is changed depending on the season or weather, the operation becomes extremely complicated. In addition, in order to grasp the operating state such as various set values and the temperature of the showcase etc., it is necessary to go to the place where the showcase etc. is installed and to individually check the data, and to collect data on the operating state of the showcase etc. Not only cannot be easily grasped, and even if an abnormal situation occurs in a showcase or the like and an alarm is issued, the related alarm is performed in each individual showcase or the like, and a large number of showcases and the like are installed. In some stores, there is a problem that it is not possible to easily grasp which showcase is generating the alarm. Therefore, for example, in Japanese Unexamined Patent Application Publication No. Hei 7-114657 (F25D11 / 00), a control device of each showcase is connected to a main control device constituted by a microcomputer (or a central management device constituted by a personal computer) by a communication line. By performing various setting work of each showcase in the main control device or the central management device, and collecting data on the operating status and alarm of the showcase in the main control device or the central management device,
In the store, showcases and the like were configured to be collectively managed by the store. In addition, when a failure such as abnormally high or abnormally low temperature occurs in each showcase or the like, data relating to those alarms is also collected by the main control device, transferred to the central control device, and then transmitted to an external device via the public line. It is configured to be transmitted to a computer of a center (the main body of the supermarket, the head office of a food processing plant, or a contracted maintenance management company).

However, in the past, since only the occurrence of an abnormality was reported to the center in the past, the center determined the operating conditions such as the showcases of each store accurately at the center. It could not be monitored and managed. The present invention has been made to solve such a conventional technical problem, and in the case of collectively managing a plurality of showcases and the like, a showcase or the like that can perform accurate management in an external center. The purpose of the present invention is to provide a centralized management device.

That is, a centralized management device according to the first aspect of the present invention collectively manages operating states of a plurality of showcases and the like.
A store-side management unit installed at a store or the like and collecting data from each showcase and the like, and a center-side management unit installed at the center side, wherein the store-side management unit and the center-side management unit use a communication line. The center-side management means performs data collection at predetermined settable intervals from time-series data when collecting data from the store-side management means. It is composed. According to the first aspect of the present invention, the store-side management means and the center-side management means exchange data via a communication line, and the center-side management means performs time-series processing when collecting data from the store-side management means. Data is collected at settable intervals from the data arranged above, so the center can grasp the operating conditions of showcases etc. of each store etc. at the center side for quick and accurate management. This makes it possible to achieve labor saving and labor saving in device management. In particular, when collecting data from the store-side management means, the center-side management means performs data collection at a settable constant interval from the data arranged in chronological order. Thus, the data can be thinned out in time, and the amount can be reduced, so that the time and cost required for communication can be reduced. The centralized management device according to the second aspect of the present invention collectively manages the operating state of a plurality of showcases and the like, and the centralized management device is installed in a store or the like and stores data from each showcase or the like. And a center-side management unit installed on the center side. The store-side management unit and the center-side management unit transmit and receive data via a communication line. Is configured to collect only selectable specific contents when collecting data from the store-side management means. According to the invention of claim 2, the store-side management means and the center-side management means exchange data via a communication line, and the center-side management means can select when collecting data from the store-side management means. Since data collection is performed only for specific contents, the center can similarly grasp the operating conditions of showcases at each store, etc., and perform quick and accurate management. It is possible to achieve labor saving and labor saving in. In particular, since the center-side management means collects data only for specific contents that can be selected, the data contents can be reduced as necessary, and similarly, the time and cost required for communication can be reduced. Can be achieved.
