Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an entry/exit display system for managing the movement of people.

[Prior art] This type of entry/exit display system was introduced in March 1985.
There was something like the one seen in the catalog of the action monitor system of Okamura Seisakusho Co., Ltd. published in May, but in this conventional example, an operation switch corresponding to the indicator lamp provided on the display panel was installed on the operation device side.
Each operation switch and display lamp are connected in series with an electric wire, and the display lamp is lit directly by the operation switch.
There was something that turned off the lights. However, this system requires as many electric wires as the number of display lamps plus one, including the common line, and there is a problem in that the more the number of display lamps increases, the more complicated the wiring becomes.

For this reason, two-wire systems have also been devised and provided. This system consists of three parts: a transmitter, a receiver, and a reference pulse generator.The reference pulse generator generates a reference pulse to synchronize the operations of the receiver and transmitter. The address was sent to each address via a transmitting/receiving line to synchronize the address sending registers provided in each transmitting/receiving section.
Then, a command area is established between these reference pulses, and
When an operation such as leaving the office is performed, the transmitter sends a corresponding signal on the same transmission/reception line as the reference pulse,
A series of pulse train I/O signals are created by combining the reference pulse with the transmitting/receiving line, and on the other hand, the receiver determines the presence or absence of signals in the two command areas for each reference pulse and determines which command area of which pulse. It was designed to detect the presence of a signal and control the display section provided in the receiving section.

[Problems to be Solved by the Invention] However, in this conventional example, the relationship between the display section and the personal name assigned in correspondence must be set in advance for each system, making it difficult to increase the number of systems. It was hot.

Therefore, the present invention realizes a two-wire exit/exit display system that can easily change the relationship between the display section provided on each desktop operating device and the personal name assigned to each display section.

When the write key 25 is pressed in this display state, the display is temporarily changed to the same figure. When the display disappears as shown in b and then returns to the display as shown in c of the same figure, it means that the data has been written to the memory 16 and the writing has been completed. In this way, a unique name number is associated with each desktop operating device 3a, 3b, 3c and each display section 7 of the display devices 4a, 4b. Additionally, update key 23a, 2

The system starts up and the controller 1
transmission calculation control means 15a and transmission/reception circuit 15b
The address is obtained by cyclic time division multiplexing of the transmission signal consisting of the start signal ST, address data signal AD, control data signal CD, parity check CH, and return signal waiting period RD shown in FIG. 9, which have been converted into a predetermined signal format by The data will be sent sequentially along the following lines. When a certain tabletop operation unit, for example, the operation unit 8 whose name number 3a corresponds to one display unit, is operated, the transmission control means 10 on the tabletop operation unit 3a is operated.
Due to the function of the transmission signal, the return signal waiting period RD
An interrupt signal is sent as a return signal. This interrupt signal is sent to the controller 1 via transmission line 2.
will be returned to. In the transmission section 15 of the controller 1, the received return signal is received and reproduced by the transmitting/receiving circuit 15b, further converted into a signal that can be delivered to the calculation control means 20 by the transmission calculation control means 15a, and sent to the calculation control means 20. When the arithmetic control means 20 determines that it is an interrupt signal, it sets it to interrupt mode,
Transmission unit 1 transmits a signal requesting return of address data.
5, and among the tabletop controllers that received this signal, the tabletop controller 3a that made the interrupt returns the address data of the tabletop controller 3a. Upon receiving this return signal, the controller 1 uses the arithmetic control means 20 to determine the address that requested the interrupt, and sends out a transmission signal to call the tabletop controller 3a to the address. and the waiting period for the transmission signal to be returned.
This causes the RD to send out the operation data of the tabletop controller 3a. When the returned operation data is received and read by the arithmetic control means 20, the interrupt mode is canceled and the controller 1 returns to normal operation. Then, display devices 4a, 4b or desktop operating devices 3a, 3b, which have a display section 7 having the same name number as the display section 7 corresponding to the operated operation section 8,
3c, the controller 1 transmits a control data signal for controlling the display section 7 based on the data in the memory 16. If the display mode is set to 2 mode, for example, the red light emitting diode _L2 is turned on or off. This control state is performed by reversing the previous state, and is reversed every time the corresponding operation section 8 is operated. In the case of 4 modes, each time the corresponding operation section 8 is operated, only the green light emitting diode _L1 lights up, and the red light emitting diode lights up.
Only L ₁ lights up, all light emitting diodes L ₁ and L ₂ light up,
Control data is created so that all light-emitting diodes L ₁ and L ₂ are switched off in the order of extinguishment to obtain a display of green, red, yellow, and extinguishment. If it is green here, go to work,
Appropriate meanings are assigned to each color, such as red indicating that the person is in a meeting, yellow indicating that the person is on a business trip, and lights out indicating that the person is leaving the office, so that the person's status can be determined by looking at the display device. Of course, the operator only has to operate the operating section 8 until the emitted light color becomes a predetermined color.

The display section 7, which is set to the name number corresponding to the operating section 8 operated in this way, displays the desktop operating devices 3a, 3.
b, 3c and indicators 4a, 4b are controlled to the same state. This operating state will be maintained until the corresponding operating section 8 is operated and the control data sent at the time of access from the controller 1 changes.

When checking the contents of the memory 16, set the selection switch SW to read mode, and press the read key 26 and keys 23a, 23b, 23c and 2.
By operating 4a, 24b, 24c, it is possible to confirm the number of the display section 7 corresponding to a predetermined name number, or the address of the tabletop operating devices 3a, 3b, 3c or the displays 4a, 4b.

By the way, the display section 7 provided in the display devices 4a and 4b is capable of displaying in four modes by light emission from light emitting diodes _L1 and _L2 , but inverted display using an incandescent lamp or a shutter-type magnetic driving force is used. When using a device, etc., only the pattern of lights off and lights on can be displayed, but when the 4-mode display is set, the following four types can be selected for the lighting and lights out state using setting switch SW ₂ . That is, it lights up against green,
A mode that is off otherwise, a mode that is on for green and red and off otherwise, a mode that is on for green and yellow, and off otherwise, and a mode that is on for green and yellow and off otherwise. 4 with the mode that lights up for
You can choose between different lighting modes.
