As shown in FIGS. 8 to 10, the screen of the personal computer PC includes a time-lapse graph G1 indicating temperature, humidity, and illuminance, respectively.
G2 and G3 can also be displayed. In addition, each broken line in these graphs G1, G2, and G3 indicates data for each display case 100.

Therefore, with such a configuration, the receiving unit 31 and the transmitting unit 2 can be configured from the same device to reduce the types of components, and the central processing unit can be omitted. The configuration of the means 3 can be simplified. Further, since each communication unit 5 has a hierarchical structure, and the communication units 5 can communicate with each other wirelessly, it is excellent in scalability and mobility as a whole device, and can flexibly correspond to the mode of an exhibition hall. It has the effect.

It should be noted that the present invention is not limited to the above-described embodiment, but can be variously modified. For example, it is possible to change the communication method between the receiving unit and the transmitting means, the arrangement and the like thereof. Also,
It is not always necessary to provide all the sensors related to each temperature, humidity, and illuminance. On the contrary, it goes without saying that a sensor for measuring, for example, the amount of ultraviolet rays or the like may be added.

Further, the information collecting apparatus according to the present invention can provide the same function and effect when applied not only to an independently movable display case but also to a fixed display case. In addition, the specific configuration of each unit is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

When installed in an art museum or a museum having a plurality of floors, one receiving section is arranged for each floor, and the receiving sections are sent from an exhibition case installed in the floor. By receiving the status signal, reasonable wireless communication can be performed. This is because it is often difficult to perform wireless communication with another floor over a floor.

The transmitting means transmits the status signal intermittently, and the transmitting timings of the transmitting means belonging to one receiving section are made different from each other so that the receiving section transmits the status signal from each transmitting means. If the system is configured so that signals can be sequentially received without overlapping in time, the situation signals sent from multiple transmission means can be reliably received without confusion and installed in the exhibition case. The power consumption of the transmitting means can be minimized and the operation can be performed for a long time without replacing the battery. Therefore, the frequency of opening and closing the display case 100 for battery replacement can be reduced, so that maintenance can be facilitated and the display item can be maintained in a suitable storage state for a long period of time.

If the central processing unit and the receiving unit are provided separately from each other and the power of the receiving unit is configured to be supplied from the central processing unit, the AC power is particularly required for installing the receiving unit. Since no power supply or the like is required, the work is facilitated and maintenance can be facilitated. If the detecting means is such that the temperature sensor, the humidity sensor and the illuminance sensor are built in one housing, the detecting means can be made less noticeable and the appearance of the display case can be kept good. Further, if the detecting means and the transmitting means are separated from each other, and only the detecting means is installed in the exhibit accommodating space provided in the display case, the appearance can be further improved.

Each of the plurality of display cases is provided with a detecting means and a transmitting means, and the information processing means is constituted by one or a plurality of receiving units which have a transmitting function and which can communicate with each other. A plurality of transmission units are assigned to the respective units, and the status signals transmitted from these transmission units are received. By connecting the monitoring unit to any of the reception units, the status of all the display cases can be monitored. With such a configuration, the central processing unit can be omitted, and the configuration of the information processing means can be simplified.

If the transmitting means is provided with a receiving function and the transmitting means and the receiving section are configured to be interchangeable, the types of components can be reduced. If the communication between the receivers is performed wirelessly, the degree of freedom of installation of the receivers and the workability related to installation or change can be improved. A communication unit is formed by one receiving unit and a plurality of transmitting units belonging to the receiving unit. One communication unit connected to the monitoring unit is a central communication unit, and a plurality of branch communication units are layered on the central communication unit. If they are structurally connected, the aspect can be changed according to the configuration of the exhibition hall, and the expandability is also enhanced. More specifically, a first mode in which the hierarchical structure is composed of only one central communication unit and has a one-stage hierarchical structure,
A second mode in which the central communication unit and one or a plurality of branch communication units capable of directly communicating with the central communication unit and having a two-layer hierarchical structure, or one capable of directly communicating with the central communication unit and the central communication unit Alternatively, it is configured such that any one of a third mode having a three-stage hierarchical structure including a plurality of branch communication units and one or a plurality of branch communication units capable of directly communicating with the branch unit can be selected. Are included.

If the illuminance sensor can be directly connected to the illuminance display, and the illuminance in the display case can be adjusted while visually recognizing the illuminance display by the illuminance display, the present information collecting apparatus can be used. The workability related to the illuminance adjustment in the case where the camera is installed can be improved.
