Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an attendance/leaving display used in a company etc. to display information such as whether an employee is at work or not, or whether he or she is out of the office. Regarding equipment.

[Conventional technology]

As an example of such entry/exit display equipment, for example, equipment for displaying personnel entry/exit, conventional equipment has an operating device having multiple operation switches corresponding to multiple entry/exit states, and the operation of those multiple operation switches. It is known that a display board having a display section that operates in response to display information based on the above is connected by wire so that each switch itself directly operates the corresponding display section.

In this system, each employee has a separate control device and operates the control switch according to his or her own entry/exit status.
For example, the entry/exit display on the display board is changed by blinking a lamp.

[Problem that the invention seeks to solve]

However, the conventional configuration described above has the following problems.

In other words, since the control device and display panel are connected by wire, if each employee's location changes due to moving desks, etc., the wiring must be rewired, which is a time-consuming process. It was something.

In addition, since the display for the number of people who should display attendance and exit on the display panel is changed directly using the operation switch of the operating device held by each employee, wiring between the display panel and the operating device is required. In addition, as many electric wires were required for each number of people, the space for wiring became larger, and the wiring work also required one hexagram of effort.

Furthermore, if display panels are installed in several locations, such as on each floor, an operating device must be connected to the display section of every display panel, and a large number of electric wires are required for wiring. This resulted in an increase in wiring space and complicated wiring work.

In view of the above circumstances, it is an object of the present invention to provide an entry/exit display facility that is flexible in the installation of operating devices, has simple wiring between display panels, and is highly workable.

[Means for solving problems]

The features of the entry/exit display equipment according to the present invention include an operation section equipped with a plurality of operation wheels corresponding to a plurality of entry/exit states;
An operating device is provided which has a modulation section that modulates display information based on the operation of the plurality of operation keys, and an output section that outputs the modulated signal of this modulation section or '') in a wireless manner. An input unit that receives output, a demodulation unit that demodulates the input signal into display information, a display unit that operates based on the demodulated display information, and an input/output unit that exchanges this display information with the outside via a wired method. and a control section that outputs display information from the input/output section and the demodulation section to the drive circuit of the display section and the input/output section.

[For production]

In other words, the display information based on the operation of the operation keys on the controller is transmitted wirelessly to the display panel and displayed, so the wiring between the controller and the display panel, which was required in the past, can be omitted. This eliminates the need for wiring work and the need to secure space for wiring.

And because you can eliminate the wiring between the controller and the display panel,
There is no restriction on the installation location of the operating device, and the operating device can be extremely easily moved to any desired installation location.

In addition, a control section and an input/output section are provided on the display panel.
Display information is input and output to the outside via the input/output unit, so even if a large number of display panels are provided, display information can be exchanged between the display panels.
It is possible to eliminate the wiring between all the display panels and the operating device, which was required in the past, and it is also possible to reduce the number of signal lines between the display panels.

〔Effect of the invention〕

As a result, the operating device can be installed extremely easily without any wiring work, and can be moved to any location, so even if there is a change in the number of personnel who should display entry/exit on the display panel,
Now you can deal with it easily.

Furthermore, since the wiring between the -1 display panels can be realized with an extremely small number of wires, the installation of the entire entry/exit display equipment can be done with less effort.

Therefore, it has become possible to provide an entry/exit display facility with extremely high workability as a whole.
