DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a radio repeater,
In particular, the present invention relates to a wireless repeater that can be directly attached to a straight fluorescent tube socket in an office or the like.

[0002]

2. Description of the Related Art Conventionally, a communication network in a general office is formed by a cable using a coaxial cable, a twist cable, an optical fiber cable or the like as a transmission medium, and a wireless communication using an electric wave, light, or the like. As for those that use wired, as long as it is wired, large-scale construction accompanying its installation is inevitable, for example, for the layout of cables, it is necessary to secure a space above the floor, under the floor, etc. Because it is necessary to give priority to being able to wire, it is often necessary to move or relocate office equipment (desks and chairs), which should be irrelevant, and sometimes the optimal layout of the office is sacrificed. Evils occur.

[0003] Next, in the case of using radio, the drawbacks caused by wiring are improved. However, in the case of using radio waves such as microwaves for communication, if the transmission power exceeds a specified value, the transmission equipment is required by law. It requires radio station licenses and management by qualified persons to operate the system, and is not suitable for general offices, and when considering communication with battery-powered mobile terminals, increase the transmission power As a result, the power consumption of the mobile terminal increases, so that the transmission power is preferably low. For this reason, the number of lines has been sacrificed by a frequency spread method or the like, or a service area in which communication is possible has been sacrificed.

[0004] If the service area of the radio is not sufficient for the size of the office, a repeater is required to relay the communication. When performing wireless communication using light such as microwaves or infrared light with a narrow service area, the transmission power is kept below a specified value, in most cases the repeaters are required, but they are installed on the ceiling with few obstacles. The installation of the repeater body and securing the power supply of the repeater also involve large-scale construction.

[0005] An example of a radio repeater in which the above-mentioned disadvantages are eliminated is described in Japanese Patent Application Laid-Open No. 61-46632. The wireless repeater described in this publication is a wireless repeater using lighting equipment in an office. The wireless repeater has a power receiving terminal that can be directly attached to an insertion port of general lighting, and is characterized by performing power supply and mechanical support by the power receiving terminal, and can be replaced with a lighting lamp.
It was also possible to attach an illuminator to the repeater body.

[0006]

In the above-mentioned conventional technology, since a communication network can be formed wirelessly without extensive construction, disadvantages in forming a wired communication network in a general office (wiring space is limited). Necessary, wiring work is required, and the installation of the terminal device is restricted by wiring). However, in a general office, the power supply system for multiple lighting lamps is integrated into one, and a single power switch can be used to turn on and off the power of multiple lighting lamps. When the wireless repeater is used, there is a disadvantage that power is supplied to the socket regardless of whether it is necessary or unnecessary to supply a plurality of lightings belonging to the same power supply system as the socket.

[0007] Further, since the repeater has only one relay module, when radio waves are concentrated, interference is likely to occur. Furthermore, since it is a repeater, the received information must be transmitted to another. However, if transmission and reception are performed simultaneously by the relay module, the relay module has a transmitter and a receiver adjacent to each other. As a result, the transmitted wave goes around to the receiving unit, and interference is likely to occur. Therefore, it is difficult to perform reception during transmission or transmission during reception, and a transmission end waiting time or a reception end waiting time is required. As a result, communication speed is sacrificed.

Accordingly, it is an object of the present invention to provide a radio repeater which can be mounted on a lighting fixture body instead of a fluorescent tube used for general office lighting, and which can simultaneously use the fluorescent tube.

Another object of the present invention is not only to eliminate the restriction that the lighting and the repeater must be turned on and off simultaneously as in the conventional repeater, but also to reduce the possibility of interference due to radio wave concentration. Another object of the present invention is to provide a wireless repeater in which a decrease in communication speed caused by interference due to a transmission wave wraparound is reduced.

[0010]

According to the present invention, there is provided a wireless relay provided in a lighting fixture main body for mounting a linear fluorescent tube, wherein a pair of sockets facing each other in a predetermined direction of the lighting fixture main body. A first module mounted on one of the sockets, a second module mounted on the other socket of the pair of sockets, and a power supply unit connected between the first and second modules; Including
At least one of the first and second modules has a wireless relay module that performs a wireless relay function, and the first and second modules have facing surfaces that face each other at intervals in the predetermined direction, A wireless repeater is provided, wherein a pair of sockets to which a linear fluorescent tube can be attached is provided on the facing surface.

Also, according to the present invention, there is provided a wireless repeater, the terminal being mountable to one of a pair of sockets provided in a lighting fixture main body for mounting a linear fluorescent tube; A first module including a socket capable of mounting a terminal of a fluorescent tube, a power supply module, and a wireless relay module that operates by receiving power supply from the power supply module, and the other of a pair of sockets of the lighting fixture body; A second module including a socket attachable to a socket and a socket attachable to a terminal of the linear fluorescent tube, and a power supply unit for connecting the first and second modules; And the second module is respectively mounted in a pair of sockets of the lighting fixture body, the linear fluorescent tube is mounted between the first and second modules, the linear fluorescent And the lighting fixture body cooperates with each other to hold the first and second modules, and the linear fluorescent tube is supplied with power through terminals and sockets of each of the first and second modules, A wireless repeater is provided in which power is supplied to the power supply module through a terminal of the first module, the power supply means, and a terminal of the second module.

As described above, since the wireless repeater of the present invention includes the storage battery for storing power, when power is supplied to the power supply terminal of the fluorescent lamp socket, the power is stored in the storage battery from the power supply terminal. It is possible. Therefore, when illumination is not required and power is not supplied to the power supply terminal, the power stored in the storage battery can be supplied to the wireless relay module to operate the wireless relay module. Further, since two wireless relay modules can be connected to one fluorescent lamp socket, the concentration of radio waves can be dispersed from one place to two places, and the concentration of radio waves can be reduced. Also, since a signal line is connected between the two wireless relay modules to enable wired communication, information received by the other relay module via the signal line can be transmitted through the signal line even while receiving by one relay module. By transmitting by the communication means and transmitting from the relay module to another repeater or information terminal, the transmitting unit and the receiving unit are separated by the distance of the fluorescent tube in the wireless repeater, so that the transmitted wave goes to the receiving unit. Interference can be prevented, and transmission and reception can be performed simultaneously.

For example, if there is no wired communication path 007, 1
One radio relay operation is performed by only one transmission / reception module, and the reception operation during transmission or the transmission operation during reception is difficult to perform due to the possibility of interference due to the wraparound of a transmission wave. Therefore, in the relay operation, only reception is performed until transmission from another relay device or information terminal is completed, and then transmission to another relay device or information terminal is performed.

However, if there is a wired communication path 007, the transmission / reception modules 003A and 003B are separated by at least the distance of the linear fluorescent tube 102.
