Therefore, on the nurse station side, the evacuation situation can be visually determined, and evacuation guidance can be carried out smoothly.

Note that when a recovery switch (not shown) provided on the base unit side is operated, the emergency indicator lights of all hallway lights and the sounding of the alarm means immediately stop, and the system is completely restored.

(Each information device in the system) In the system of the present invention, during normal use, the controller for multiplex transmission control and the nurse call
A variety of terminal units are used, such as a calling unit, a calling unit, a calling information display device, etc., such as a handset, a calling unit, and a calling information display device, and their respective configurations will be explained below.

(controller) FIG. 4 is an external configuration diagram of the controller.

As shown in the figure, the controller C has a channel number display section 22 . . . that displays the channel code assigned to each of the individual display operation sections 11 . Corridor light number and position number display sections 22a and 22b assigned to the hallway lights, and hospital room number display section assigned to the vent position of the hospital room (number display sections 22a and 22b mentioned above)
) and a patient number display section 23 on the front panel 24, as well as a nurse call display on the terminal unit! II! A numeric keypad 25 is provided for setting and changing the address that defines the lighting position in the list display operation section 10 of the IIA. In addition, 15 is a power switch, 16 is a mode selection switch, 17 is a data changeover switch that switches data input to hospital room and corridor lights, 18 is a test mode execution switch, and 19.20 is an input by operating the numeric keypad. An operation switch 21 is used to register and confirm the data, and 21 is an operation key used to reset the data.

FIG. 5 shows the basic internal circuit configuration of such a controller C, which includes a transmission control means 1a for transmitting and receiving multiplexed signals, and a transmission control means 1a that decodes the transmitted and received signals and performs necessary processing. an arithmetic control means 1b that sends out control signals; a memory IC that stores programs and data necessary for control;
The operation mode of the controller C is defined, and the calculation control means 1
Operation mode control circuit 1 for setting b to a selected mode
e, a setting switch 1f for changing and setting the operation of the controller C and the contents of data stored in the memory IC;
It is provided with a key input circuit 1d for inputting the operation of the setting switch 1f as input data to the arithmetic control means 1b, a display drive circuit 1g for displaying the input data, and a display 1h.

The setting switch 1f is composed of a numeric keypad 25 for inputting and updating data, and various switches 16, 17, and 18 such as a mode setting switch, and the memory lc is composed of a rewritable volatile memory. Back amplifier means (not shown) is provided to prevent stored data from being erased in case of a power outage.

In the controller C having such a configuration, when the normal mode is selected by the mode setting switch 16, the multiplex transmission control means 1a of the controller C outputs a start signal as shown in FIG. 6 converted into a predetermined signal format. S
T, address data AD, control data CD, parity check CH.

A transmission signal consisting of the return waiting time RD is cyclically sent out to each terminal unit in the system in sequence according to the set address using a time division multiplexing method.Then, the call switch of one of the terminal units in the system is operated. and, in that unit, a transmission control means (not shown), which will be described later.
operates to return an interrupt signal as a return signal during the return signal waiting time RD of the transmission signal. This interrupt number 43 is sent back to the controller C via the multiplex transmission line 1, and the multiplex transmission control section 1a of the controller C receives and reproduces the received return signal, and further sends it to the arithmetic control means 1b.

When the arithmetic control means 1b determines the interrupt signal, the interrupt mode is executed, causing the transmission control means 1a to send out a signal requesting return of address data, and causing the terminal unit that issued the interrupt to return the address data. Upon receiving this return signal, the controller C transmits the arithmetic control means 1
The address that requested the interrupt is determined in b, a return signal is sent to call the calling unit at the corresponding address, and the calling data is sent during the return waiting time RD of the transmission signal. Then, it receives this returned data and stores it in memory 1.
When the arithmetic control means 1b calls the interrupt mode, the interrupt mode is canceled, the controller C returns to the normal mode, and sequentially accesses the next terminal unit.

In this way, when accessing the nurse call base unit A, it is possible to access the nurse call base unit A according to the position information (address) on the list display operation unit 10 of the nurse call base unit A of the terminal unit obtained by referring to the memory IC in the controller C. At the same time, the display section 11a of the corresponding individual display operation section 11 is turned on.
The corresponding display section of the hallway light provided on the side of the hospital room where the call was made and the representative hallway light E are turned on. Here, in the example, nurse call child 4! ! In response to the call from B, the display unit 11a of the nurse call base unit A is lit in a different color depending on the purpose of the call, so at the nurse station, By looking at this lighting pattern, the purpose of the call can be immediately determined.

(Nurse Call Parent II) As shown in FIG. 1, the external structure of the nurse call intercom parent unit A is as shown in FIG.
．． It has an emergency indicator light 14. Then, this base unit A is used for each nurse call child @B in the system, representative light F with a recovery button.
It is equipped with a list display operation section 10 consisting of a plurality of arrays of a plurality of individual display operation sections 11 corresponding to terminal units such as calling units consisting of the individual display operation section 11.
. . . each has a display section 11a with an indicator light, a display plate 11b2 on which a hospital room number or patient name is written, and an operation switch llc for channel selection.

(Hereinafter, So'ra> Figures 7 and 8 show the nurse call parent mA list display operation section 11 in more detail.

Body frame frame 1 configuring each individual display operation section 11
Approximately on the right half of 10, a horizontally long groove of an appropriate depth is provided to form a name display section 11b, and above this horizontally long groove 11b,
A tapered part 11 inclined in the depth direction is provided at the right end of the lower window frame.
6a and a wide opening edge 116b are provided to facilitate insertion of the name plate. This name display section accommodates a name plate on which unique patient information such as the patient's name and bed number is written.

Further, approximately on the left half side of the main frame frame 110, a horizontally long groove 117 having an appropriate depth, which is smaller than the horizontally long groove of the name display section, is provided.
This horizontally elongated groove forms a nursing information display section 117 in which the patient's medical condition and information necessary for nursing care are displayed, and includes a tapered section 117a similar to the name display section described above and a wide opening edge 117b. This makes it easier to insert the information plate.

Note that 111 is a room number display section, Ilc is a channel selection switch for connecting a line, and lla is a call indicator lamp.

On the other hand, approximately in the center of the main frame frame 110, there is a
A rectangular groove of an appropriate depth is formed between the two horizontally long windows 11b and 117, and this rectangular groove constitutes the relief category information display section 118.

This rectangular groove 118 has an appropriate depth to which a steel bottom plate 118a is attached, and an opening 118b is formed approximately in the center of the bottom plate 118a, and a Hall element 119 is provided below the opening. ing.

This shows an OFF type in which the magnetic sensing element 119 is inactive because the magnetic seal at the location 130C facing the 130C is removed. In these examples, two types of signals can be extracted depending on whether the magnetic sensing element 119 is activated or deactivated, but the present invention is not limited to this example. It goes without saying that if the manner of attachment B of the magnetic material on the back surface of the color plate is defined in accordance with the combination of operating conditions, it is possible to extract several types of signals.

Normal relief classification information for each patient is ``stretcher required'', ``accompaniment required'', and ``able to walk independently''.
Since it is sufficient to be able to classify the types, it is sufficient to provide two magnetic sensing elements and prescribe the color coding of the color plate according to the combination of the operating states of the magnetic sensing elements.

Further, as the magnetic sensing element, a Hall element scaled switch can be easily used, and a permanent magnet piece may be directly attached to the back surface of the color plate.

The signals retrieved by such means can be used to control the hallway lights, E, and E.
It is sufficient to display the relief information axis on the necessary display device (for example, a method such as providing a relief information display lamp and changing the lighting color depending on the relief category), and this will improve evacuation activities. This makes it possible to do this even more smoothly.
