There is.

In operation, the current consumed by the power supply line 10 can be measured by the current measuring device 20. From this measured current value, CP
U21 is configured to determine which sick bed in the hospital room 4 the push button operated by the patient.

Further, as shown in FIG. 3, the patient-specific corridor lamp device 12 has the power line 10 when the push button switch is pressed.
There is an indicator lamp 12b that lights up via
b is made to blink by the reset button. The patient-specific corridor light device 12 has a calling circuit described below.

FIG. 9 is a schematic diagram of the calling circuit. This calling circuit corresponds to the case where there are four beds in the room 4 and one toilet, and correspondingly, a plurality of latches 79 (circuits for registering information) are provided. Each of the latches 79 has set and reset input terminals S and R, and the set input terminals S are connected to the push button switches of the respective devices connected to the wiring 13 through the wirings 80 to 84, respectively. There is.

Each latch 79 has a push button switch 14
When any one of to 16 is pressed, the corresponding latch 79 is set, and once set, functions as a switch that connects the cathodes of the light emitting diodes 69 and 75 to 78 connected to the set latch 79 to ground. To do. Further, each latch 79 is reset when the reset button switch 90 is pressed, and once reset, the light emitting diodes 69, 7 connected to the reset latch 79 are reset.

Constant current means 70 to flow a predetermined current to the anodes of the light emitting diodes 69 and 75 to 78, respectively.
74 is connected. These constant current means 70-74
Are set to different current values.

For example, the constant current means 71 is 50.00 m
A, constant current means 72 is 50.01 mA, constant current means 73
Is 50.02 mA, the constant current means 74 is 50.04 mA,
For the toilet push button switch 14 and other hospital rooms, constant current means (for example, 5
0.10 mA, 50.11 mA, 50.12 mA, 5
0.14mA, the next room is 50.20mA, 5
For example, 0.21 mA, 50.22 mA, 50.24 mA, etc., each digit except for the tens digit is numerically composed of 0, 1, 2, and 4, and even if currents flow simultaneously by these constant current means, any constant It is possible to judge whether or not the current is consumed through the current means), and each constant current means is set to have a unique current value for one of the push button switches. .

These constant current means are connected to the power supply line 10 through the power supply line 70 '. The corridor light 11 is a power line 70 '
The fact that a current has flowed through is turned on via the detection means 68.

Next, how the display power supply device 8 can determine which of the push button switches 14 to 16 has been pressed will be described by taking as an example the case where there are four beds in the hospital room 4. To do.

When any of the push button switches 14 to 16 is pressed, a signal is sent to the patient corridor lamp device 12 through the wiring 13 and further through the wirings 80 to 84, and the signal is sent to the set input terminal S of the specific latch 79. A signal is input. As a result, the specific latch 79 is set, and the corresponding specific one of the light emitting diodes 69, 75 to 78 corresponding to the indicator lamp 12b of FIG. 3 connected to the specific latch 79 corresponds to the patient name. And is emitted.

Here, for example, if the light emitting diode 76 emits light, the constant current means 72 causes a current value of 50.0.
1 mA is consumed. This consumed current value flows through the power supply line 10 and the current measuring device 20 of the display power supply device 8
The CPU 21 in the display power supply unit 8 determines from which measured value the push button was pressed, and the determined bed lights up on the corresponding indicator lamp 9a of the display power supply unit 8. Is displayed.

In this embodiment, a plurality of push button switches 14
Even if ~ 16 is pressed, it can be dealt with. Below, pushbutton switches 14 to 1 for a plurality of hospital beds
The case where 6 is pressed will be described. For example, assume that there are 60 locations where push button switches are installed.

In this case, when the current value of the constant current means is set as in the above example, the constant current value is 50.00 mA, 5
0.01 mA, 50.02 mA, 50.04 mA, 5
0.10 mA, 50.11 mA, 50.12 mA, 5
0.14 mA, 50.20 mA, 50.21 mA, 5
0.22 mA, 50.24 mA and the maximum value is 54.
It becomes 24mA. Therefore, by dividing the current value (mA) consumed through the power supply line 10 by 50, the number of pushed pushbutton switches can be known, and which pushbutton switch is found from the remainder divided and the number of pushed buttons. You can judge whether was pressed.

With the above configuration, it is possible to judge which push button switch is pressed by the current consumption value via the power supply line 10. Therefore, it is necessary to install a separate signal line only for this judgment. Since there is no need, the wiring work can be greatly omitted, and even when the wireless information transmission is insufficient due to poor radio wave conditions, it is possible to know from which hospital bed the call was made. A nurse call system can be provided.

FIG. 10 is a schematic diagram showing another aspect of the calling circuit.

Reference numeral 85 in FIG. 10 is a protection resistor for controlling current. Reference numeral 100 is an oscillating means outputting a reference frequency.

Numerals 95 to 98 are latches when the number of beds is four, which functions in the same manner as the latch 79, receives the reference frequency output from the oscillating means 100, and sets the frequency freely to a positive value. It is a latch for lighting which can be divided by an integer and can make the light emitting diodes 69, 75 to 78 light at the divided frequency.
That is, when any one of the push button switches 14 to 16 is pressed, the corresponding light emitting diode 69, 75 to 78 is turned on at the frequency set to its own value by the lighting latches 95 to 98. There is.

Further, in this case, the display power supply device 8
Is equipped with a frequency measuring device capable of measuring the frequency at which the consumption current changes, and is provided with a CPU capable of determining which hospital room push button switches 14 to 16 are pressed when the measured frequency value is input. There is. Further, this frequency measuring device can measure a plurality of frequencies separately. Therefore, for example, at the same time, the push button switches 14 to 1
Even if 6 is pressed at several places, this frequency measuring device can discriminate and judge the frequency, so that it is possible to know where the push button switches 14 to 16 are pressed.

That is, in the case of this example, the frequency at which the consumption current through the power supply line 10 changes is measured by the frequency measuring device provided in the display power supply device 8 in place of the current measuring device, and the measured frequency is displayed. CP provided in the power supply device 8
It is input to U21, and this CPU 21 can determine which push button switch 14 to 16 is pushed, another signal line can be omitted, and even when wireless information transmission is insufficient, It is possible to provide a reliable nurse call system capable of knowing whether the call is made from the push button switch by the display via the CPU 21 provided in the display power supply device 8.

As described above, in the present invention, the power supply line 10 is used not only for supplying power, but also as an information transmission line for clarifying the place of information transmission, so that the number of wirings can be reduced.

Although the above embodiment does not exemplify a nurse call system having a digital line, it can be applied to a nurse call system including a digital line.
That is, the power supply line 10 is used for supplying power, and a digital line is separately drawn from the nurse center 3 to the patient-specific corridor light device 12 on the patient room 4 side, and respective digital signals corresponding to ON and OFF from the above-mentioned push button switches are supplied. You may make it generate | occur | produce, it may transmit to the nurse center 3, and the display part 9 may be operated. In this case, compared to the above-described embodiment, it takes more time and effort to draw a digital line, but since a digital circuit can transmit a large amount of information as compared with an analog type, as before, each line from each device is connected to the nurse center. Wiring work can be significantly simplified as compared with wiring to the 3 side.

[0048]

According to the present invention, the nurse call system is constructed by wireless and wired, and the nurse center side and a plurality of devices for calling from the patient side provided in the patient room are connected by the power line, and Since the power line is used for supplying power to devices and for transmitting call signals, wiring work can be significantly reduced, so it is economical and can reliably call the nurse center in an emergency. You can get a call system.
