Description

The present invention relates to a usage status management system that enables the usage status of a conference room or a meeting corner to be confirmed remotely.

  Conventionally, in a conference room or reception room, a replaceable display plate that displays “in use” on the front and “vacant” on the back, for example, is used at the entrance of the room. In this case, the display plate is displayed as “in use”, and when the room has been used, the display plate is replaced with the display plate on the back and “empty” is displayed.

  In addition, when an electric display device is provided at the entrance of the room and the room is used, the person in charge at the reception or the like operates the control device to turn on the electric display device in the corresponding room, for example, to indicate “in use”. Illumination is displayed, and when the use of the room is finished, the electric display device is turned off by the operation of the control device and the illumination display of “in use” is stopped.

  In addition, in order to manage occupancy in a company dormitory, etc., an operation panel provided for each room is provided at the entrance to operate the occupants when they go out. When you switch the switch in your room to the out-of-door position, a signal is sent to the management display panel installed in the manager's room, etc. via the transmission unit to display the absence, and when you return home, There has also been proposed an occupancy management system in which a signal is sent to a management control panel via a transmission unit to switch to occupancy display when operated to a room position (Patent Document 1).

JP-A-5-028387

  However, it is easy for the display plate to be displayed with the front and back sides switched depending on the room usage status, but it is necessary to check the usage status of the room by going to the location. There is a problem that smooth use is not possible unless there is sufficient communication between the department managing the use and the user.

  In addition, even if there is an electric display device installed outside the room that informs the usage status of the conventional room, go to the location of the room usage or contact the receptionist who manages the room. If the room is empty after use, the user must go to the reception desk to notify him / her and turn off the electronic display device. Despite not being used, the electric display device may indicate that the device is in use, and the use management may not be smoothly performed.

  Also, in the occupancy management system that displays the occupancy and absence status of a large number of rooms such as dormitories on the management display panel, it can be operated according to the usage status away from the room to be managed. Because the operation panel is arranged with switches to be used, when applied to the use management of conference rooms, etc., the correspondence between multiple conference rooms to be used and the switches on the operation panel is unclear. There is a problem that it is difficult for a person to operate.

An object of the present invention is to provide a usage status management system that displays a status of a usage target such as a room at a usage location and enables easy and easy confirmation in real time even at a remote location.

In the above embodiment, the usage status management system is targeted for use in executive rooms, reception rooms, meeting corners, shared toilets, etc., but in addition to this, parts supply on the factory production line, factory production Calling line troubles, displaying out of stock on warehouse shelves and product display shelves, busy situations such as talking on mobile phones, preparations for private rooms at supermarkets and restaurants, hospitals and nursing homes It can be applied to the management of various usage targets such as calling nurses and caregivers.

  In this case, as the first status information and the second status information displayed on the display plate device and the processing device, for example, it is displayed whether the parts are supplied normally or out of stock in the factory production line, and is normal in the trouble call of the factory production line. It is displayed whether the product is out of stock in the warehouse shelf or product display shelf, etc., and it is displayed whether it is waiting or taking in in the situation where the mobile phone is busy. In the preparation status of a private room at a supermarket or a restaurant, preparation or completion is displayed, and a call of a nurse or caregiver in a hospital or care facility displays whether it is waiting or in call.

(Single status display corresponding to usage status)
In the above embodiment, the status of the object to be used is displayed by switching between the vacant room and the in-use state for the reception room, for example, but either state, for example, only the vacant room or used Only the inside may be displayed.

(Portable processing equipment)
In the above-described embodiment, a personal computer connected to a LAN line is taken as an example of the processing device. However, instead of the wired communication unit 42 of the repeater 12 shown in FIG. The status notification signal received from the mobile station is converted into an HTTP protocol radio signal by the repeater 12 and transmitted, and received by a portable processing device such as a tablet terminal in the communication area to display the usage status on the screen. Also good.

(HTTP)
Although the implementation mobile uses TCP / IP for communication between the repeater 12 and the processing device 14, a hypertext transfer protocol (hereinafter referred to as "HTTP") may be used instead.

  In this case, the repeater 12 receives the status notification signal of the specific low-power communication protocol transmitted by the display plate device 10 and converts it into an HTTP status notification signal known as a request-response type protocol for processing. Transmit to device 14.

  In this HTTP, the repeater 12 functions as a client, the processing device 14 functions as a server, and the relay device 12 is an address that identifies the display plate device 10 based on the status notification signal received from the display plate device 12. And a request message in a packet format including the status information indicating the usage status in the data part, and notifies the processing device 14 of this as a status notification signal converted into HTTP.

  Based on the HTTP status notification signal (request message) received from the repeater 12, the processing device 14 displays “vacant” or second status information indicating the first status information selected and displayed on the display plate device 10. The status corresponding to “in use” is displayed on the screen.
