DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings.

In FIG. 1, reference numeral 1 generally indicates the configuration of a mobile unit managing apparatus for managing the whereabouts of doctors, patients, etc. in a hospital, for example, to set a user identification code for identifying a doctor, a patient, etc. Remote control (remote control) that sends out as infrared light of remote control format 2
Is attached to a doctor or a patient, and infrared light sent from the remote controller 2 is received by a plurality of monitoring devices 3 installed at predetermined positions such as ceilings of patient rooms or passages at predetermined intervals, and each monitoring device 3 monitors each. A doctor is added with a position identification code indicating the position of the device, and the user identification code and the position identification code are transmitted to a code data processing unit 5 installed at a nurse center, for example, via a bus line 4 formed of a coaxial cable. The locations of doctors, patients, etc. are displayed on the monitor 6 by detecting the locations of patients, patients, etc.

As the remote controller 2 to be carried by each user such as a doctor or patient, an existing consumer card type remote controller using a battery for controlling a consumer TV or VTR is used.
First, the user data encoding section 7 of the remote controller 2 sets a user identification code corresponding to the user data by switching of the switching section 8, and adds this to the remote controller code which is a remote controller format for consumers. Further, the user data encoding unit 7 is provided with keys for emergencies, tests, etc., and is used during emergencies or tests as needed.

The remote control code to which the user identification code is added in this way is sent out as infrared light from the LED (light emitting diode) section 10 by the driving section 9 made of a transistor. Since the remote control code is transmitted as infrared light as described above, the transmission range is about 7 compared to radio waves.
It is limited to the range of [m] to 10 [m] and the area can be limited, so that it does not affect other receiving devices and the like.

Further, in this case, the user data encoding unit 7
Is a microcomputer, C equipped with a timer
The PU is used to control the light emission interval. That is, the infrared light is not always emitted from the LED unit 10, but is automatically emitted at regular intervals such as 30 seconds or 1 minute as shown in FIG. In this way, if the infrared light is emitted intermittently by using the timer of the CPU itself as it is, it is not necessary to provide a new timer in the monitoring device 3 and no extra cost is required. Further, since the infrared light is intermittently emitted, the life of the battery of the remote controller 2 can be extended, so that the battery usage efficiency can be improved, and accordingly, the cost of the mobile management device 1 as a whole can be reduced. be able to. If, for example, an AA battery is used to emit light at 1-minute intervals and it is used for 8 hours, it can be used for about 120 days.

The monitoring device 3 is arranged in a block unit (for example, a room unit such as a patient room) for specifying a place, and is arranged on the ceiling of each patient room or passage as required. Therefore, each user must attach the remote controller 2 so that the infrared light goes toward the ceiling. When the light receiving unit 11 of the monitoring device 3 thus installed receives infrared light, the light receiving unit 11 converts the remote control code with the user identification code into the remote control code decoding unit 1
Send to 2. The remote control code decoding unit 12 decodes the received remote control code to extract necessary data, that is, a user identification code. A position identification code corresponding to the position data of each monitoring device 3 set by switching in the position data encoding unit 13 is added to this user identification code and output to the remote control code encoding unit 14.

The remote control code to which the user identification code and the position identification code are added is encoded by the remote control encoder 14 and a signal corresponding to the remote control code is input to the transistor pair Q1 and Q2. The input signal is transmitted to the secondary coil 16 via the primary coil 15 of the pulse transformer driven by the transistor pair Q1 and Q2, and is transmitted to the bus line 4 as a pulse waveform.
Before sending a signal to the bus line 4, the bus line 4
Is checked by the data bus busy detector 17. That is, the data bus busy detector 1
7 is the bus line 4 from the signal S1 from the transistor Q3
Is detected and the signal S2 based on this is sent to the remote control code encoder 14. Therefore, the remote control code encoder 14 outputs a signal corresponding to the remote control code based on the control signal S2 from the data bus busy detector 17 when the bus line 4 is free.

The signal input as a pulse waveform via the bus line 4 is input to the transistor Q4 via the pulse transformer 18 of the code data processing unit 5, amplified by the transistor Q4 and input to the code data decoding unit 19. . The code data decoding unit 19 decodes the remote control code based on the input pulse waveform, and displays the user data corresponding to the user identification code on the monitor 6 for each position data corresponding to the position identification code as shown in FIG. Let

Here, the position data and the user data displayed on the monitor 6 can be saved as data at predetermined time intervals. Therefore, by referring to these past data, even if there is no data of the person seeking to find on the monitor 6, it is possible to know where the person seeking to find is several minutes ago, for example. Because you can, you can refer to this to find the person.

In the above structure, as shown in FIG. 4 (plan view of the hospital), a monitoring device (shown by a dotted line in the figure) is installed on the ceiling of each hospital room and at the ceiling of the passage, for example, 5 [m].
A description will be given of a usage example of the mobile unit management device when the code data decoding unit 20 and the monitor 21 are installed at intervals and are installed in the nurse station.

For example, if doctor A is examining a patient in room 8, the remote control code from doctor A's remote control 2 to monitor 8A in room 8 with the identification code of doctor A is infrared light toward the ceiling. Is automatically emitted intermittently. When the monitoring device 8A receives this infrared light, a position identification code corresponding to the position data of room 8 is added to this remote control code, and the remote control code to which the user identification code and the position identification code are added is based on the control signal S2. And is sent to the code data processing unit 20 via a bus line (not shown). The remote control code is the code data decoding unit 20.
The user data corresponding to the identification code of the doctor A is displayed on the monitor 21 in the position data column corresponding to the position identification code of room 8 on the monitor 21. With this, the nurse or the like can easily know which patient the doctor A is examining in which room by looking at the monitor 21, and can immediately respond to an urgent business. .

Further, for example, if the patient A is absent and the whereabouts cannot be known when the doctor A visits the room B to examine the patient B in the room 1, search the user data of the patient B on the monitor 21. It is possible to easily know where the patient B is. In this case, since the patient B is not always in a place where the infrared light emitted from the patient B can be received, there may be a case where the patient B cannot immediately find it. However, as described above, the user data is collected at predetermined time intervals. When the position data is stored, the data can be used as a clue for finding the patient B.

According to the above configuration, a consumer TV or VT
CP built into the existing remote controller 2 used in R
Infrared light is automatically emitted intermittently using the U timer, and the remote control code of the remote controller 2 is used to identify the user and the position identification code for identifying each monitoring device. By adding the above, it is possible to easily manage the whereabouts of the user who moves arbitrarily in the hospital, and to realize a mobile management device having a simple configuration as a whole. Moreover, since the efficiency of use of the battery of the remote controller 2 can be improved, the cost of the management device as a whole can be significantly reduced. Therefore, it is particularly effective in terms of cost when used in a facility where many people gather. Furthermore, since the remote control code is transmitted as infrared light to limit the transmission range, it is possible to significantly reduce the influence on other receiving devices and the like.

In the above embodiment, the user data is displayed on the monitor 6 for each position data. However, the present invention is not limited to this, and any display method can be used so that the user's whereabouts can be known. The position data and the user data may be displayed on the monitor 6 by another display method.

In the above-described embodiment, the case where the user data and the position data are displayed on the monitor 6 has been described, but the present invention is not limited to this, and a sketch of the accommodation facility such as a hospital is displayed on the monitor 6 (for example, FIG. 4) is displayed, and user data of doctors, patients, nurses, etc. are displayed at appropriate locations on the sketch based on each data decoded by the code data processing unit 5 to visually identify who is where. You may be able to judge.

Further, in the above embodiment, the case where the user data and the position data are displayed on the monitor 6 has been described, but the present invention is not limited to this, and the name and hospital room of the person corresponding to the user data and the position data. Numbers and the like are recorded in advance in association with the user data and the position data, and instead of the user data and the position data, the name of the person, the room number, etc. are displayed on the monitor 6 to instantly find out who is where. You may be able to grasp.

In the above embodiment, the LED section 1
The case where the infrared light emitted from 0 is automatically emitted intermittently at intervals of 30 seconds to 1 minute has been described, but the present invention is not limited to this, and the emission interval may be changed as necessary.
