JPS6146632A - Radio data repeater - Google Patents

Abstract

PURPOSE:To eliminate the need for the special power wire and installation space for a repeater by providing a power reception terminal for power reception and mechanical support to the repeater and adopting the shape as the same shape as a receptacle of a conventional lighting fixture. CONSTITUTION:The radio data repeater is loaded to a fluorescent light housing 8b provided on a ceiling 1. The power reception terminal 151 for power reception and mechanical support is provided to the radio data repeater 15, and its shape is made to the same one as a connecting terminal 91 of a conventional light fluorescent light 9. Through the constitution above, a radio data network in an office is constituted instantly. Further, the lost lightness is receovered by fitting a lighting lamp to the repeater.

Description

TECHNICAL FIELD The present invention relates to a wireless data repeater, and more particularly to a wireless data repeater having a seven-pointed shape and similarly replaceable with a lighting lamp in an office. Regarding.

BACKGROUND OF THE INVENTION Conventionally, this type of wireless data repeater has been mounted on the ceiling of an office using metal fittings or the like. Therefore, when installing a new wireless data relay network, it was necessary to construct the ceiling and also to install power supply wiring.

FIG. 1 is a diagram showing an example of the configuration of an office wireless data transmission system using a conventional technology. In FIG. 1, a wireless data repeater 5 is a data terminal 4 installed on a desk 3.
Data transmission is carried out between U2 and U2 through a radio channel consisting of Dl and U1, respectively, and with other repeaters or exchanges, respectively. U2 and U3. This is a system that performs data transmission using the U3 wireless channel. Here, the wireless repeater 5 needs to be fixed to the ceiling 1 with a metal fitting 7, and receives power through a power supply cable 6.

Therefore, in offices other than newly built offices, it is difficult to carry out extensive construction work on the ceiling 1, which is weak in strength, takes 9 hours, and has aesthetic problems.

OBJECTS OF THE INVENTION The present invention has been made to eliminate the above-mentioned drawbacks of the conventional technology, and therefore, an object of the present invention is to enable a wireless data repeater to be directly mounted on a lamp holder in a general lighting device. An object of the present invention is to provide a new wireless data repeater that eliminates the need for new construction work on the ceiling, which is usually structurally weak like conventional repeaters.

Structure of the Invention In order to achieve the above object, a wireless data repeater according to the present invention wirelessly transmits and receives data to and from a data terminal device, etc.
A wireless data repeater that transmits and receives data wirelessly with another repeater or data exchange device, which is equipped with a power receiving terminal for receiving and mechanically holding power, and the shape of the power receiving terminal is a common lighting lamp or a wall. It is configured to match the socket of the light lamp.

Embodiments of the Invention Next, preferred embodiments of the present invention will be specifically explained with reference to the drawings.

FIG. 2 is a schematic configuration diagram showing a first embodiment of the present invention. In FIG. 2, the same reference numerals as in FIG. 1 indicate similar elements. A wireless data repeater 15 according to the present invention is mounted on a fluorescent light housing 8b provided on the ceiling 1. All you need to do is remove one fluorescent light lamp 9 used for a ceiling light and attach the wireless data repeater 15, which has a power receiving terminal 151 of the same shape as the fluorescent light lamp's power receiving terminal 91, to the lamp. Communication with the wireless data repeater 15 is immediately possible via the antenna 41 of the data terminal device 4 installed on the desk 3.

In the case of an office with a large floor, an extensive wireless network can be easily constructed by replacing the fluorescent lamps in the required proportions with the wireless data repeater 15 according to the invention. In addition, the lighting lamp that can be replaced is not only a fluorescent lamp, but also a screw-in type power receiving terminal such as an incandescent light bulb.

FIG. 3 is a sectional perspective view of a main part showing a more specific embodiment of the wireless data repeater shown in the first embodiment of FIG. 2. The wireless data repeater 15 receives and holds power through a power receiving terminal 151 like a fluorescent lamp. Power receiving terminal 1
The power section 152 supplied with power by 51 is connected to the wireless circuit section 15.
The wireless circuit section 153 performs wireless transmission with data terminals and other repeaters using a plurality of antenna groups 154 and 155.

FIG. 4 is a schematic configuration diagram showing a second embodiment of the present invention. In FIG. 4, reference number 5 indicates a wireless data repeater, and this embodiment is an example in which the wireless data repeater 5 according to the present invention is replaced with an incandescent lamp 9, and the brightness is insufficient when the number of lamps is small. To compensate for this, an incandescent lamp 19 can be attached to the end of the wireless data repeater 5.

Effects of the Invention As explained above, the present invention miniaturizes a wireless data repeater, makes its power receiving terminal part the same shape as a lighting lamp generally used for indoor lighting, etc., and therefore replaces the lighting lamp and data repeater. This has the advantage of immediately configuring a wireless data network within the office. In addition, in order to restore the lost brightness, it is possible to attach lighting lamps to the wireless data repeater, and it is also possible to prevent the environmental conditions in the office from deteriorating.
