, 23 is an earphone terminal, 24 is a BGM (off) switch, 25 is an individual ID setting switch, and 26 is a group ID.
It is a cancel switch.

In the receiver as described above, the antenna 1
To demodulator 10 are the same as in the conventional example. The audio broadcast signal demodulated by the demodulator 10 is sent to the low frequency amplifier 19 via the audio switch 18 controlled by the microcomputer 15, further amplified by the power amplifier 20, and then reproduced by the speaker 21. Earphone terminal 23
It is also possible to play from. Voice switch 18
Is controlled by the microcomputer 15, and the BGM
When the (off) switch 24 is turned off, it is turned on to reproduce the BGM broadcast, and when the BGM (off) switch 24 is turned on, it is turned off and the BGM is played.
In the case of a staff member who does not need the BGM broadcast and does not need the BGM broadcast, the BGM broadcast does not get in the way. Also,
The audio switch 18 is naturally turned on so that the audio broadcast or the emergency audio broadcast can be reproduced even when the own device is designated.

Whether or not the own device is designated can be detected by applying a signal obtained by amplifying the output of the amplitude limiter 9 by the control signal amplifier 11 to the microcomputer 15 via the control signal converter 17, and the microcomputer 15 , The call ID code in the control signal given from the control signal converter 17 and the individual I set by the individual ID setting switch 25.
D, the group ID stored in the built-in RAM, and the emergency ID stored in the ROM are compared with each other, a match is detected, the voice switch 18 is turned on when the match is detected, and the voice in the control signal is detected. A command is given to the first local oscillator 4 in accordance with the broadcasting channel code to set the instructed audio broadcasting channel. Even in the normal time, the microcomputer 15 detects the state of the BGM (off) switch 24 and controls the on / off of the voice switch 18 according to the state.

Further, the microcomputer 15 also takes in the group ID transmitted by including it in the control signal and sets it in the built-in RAM. This group ID can be canceled by operating the group ID cancel switch 26. . Although the individual ID is set by the individual ID setting switch 25, the individual ID set by the individual ID setting switch 25 is printed or stamped on the outer surface of the receiver case so that it can be recognized from outside the receiver.

And the individual ID assigned to the outer surface of the receiver case do not have to be exactly the same, and may be different as long as their corresponding relationship is known.

As described above, this receiver sets the reception channel to the control signal channel, receives the control signal (also for BGM broadcasting), and sets the call ID code included in the control signal to be the same as the receiving ID code. When it matches the ID of the device, the first local oscillator 4 is controlled to set the receiving channel to the audio broadcasting channel corresponding to the audio broadcasting channel code included in the control signal, and the audio broadcasting sent from the transmitting device. To receive and play. When the call ID code matches the emergency ID code, the emergency broadcast is received with the receiving channel set as the control signal channel. Also, in the case of a receiver on another reception channel, the transmitter broadcasts the emergency broadcast by all the audio broadcast transmitters 52a to 52e, so that the emergency broadcast can be received.

In addition, even when a ringing tone is emitted before broadcasting,
It suffices if the transmitter has a sounding device, and a sounding device such as a buzzer is not required on the receiver side. The features of the configurations of the transmitter and the receiver used in this communication method will be further described below. Conventionally, a receiver has a fixed electrical code (hereinafter referred to as an ID) to call the receiver, and the receiver is called when the codes match, but the group and emergency (all receivers) Etc., the special calling method, etc.
A method of continuously sending a large number of IDs by using a CPU or the like on the sending side (transmitter) is adopted.
A PU and software are required, and the operation becomes complicated when setting or changing the call group. In addition, the ID transmission time at the time of group call is required for the number of receivers, which may affect the call of other receivers.

On the other hand, in this embodiment, the calling code is a combination of an ID designating a receiver and a control code for setting a channel code for audio broadcasting, a group ID, etc., and the receiver has a plurality of fixed ID codes. (Individual ID
(Problem set by mechanical switch), emergency ID (set by ROM), and a plurality of settable IDs by control code (group ID, for example, stored in RAM) solves the above problem. Also, in order to distinguish what kind of ID it is on the receiver, the state of the receiver can be set, for example, by setting the ringing tone to be loud or soft for this ID, It can have many characteristics.

FIG. 3 is a schematic diagram showing an example of the calling code. In the figure, the fixed ID includes an individual call ID and an emergency call ID, and the settable IDs include, for example, A to n.
It is shown that there is a group call ID up to and the control code is used to change the receiving channel, set / change the ID, and set / change the state. Here, as described above, the individual IDs have different codes for all the receivers. The emergency ID has the same code in all receivers. The group IDs A to n have a code common to a group of receivers, are called by a fixed ID (individual ID), and are subsequently set and canceled by the code included in the control code.

Further, in the control code, the change of the reception channel means that the control code specifies the channel code for audio broadcasting in order to carry out more transmission. In the receiver, the control signal channel specified by the control code This refers to shifting the receiving channel to an empty channel (audio broadcasting channel). Also,
The state setting is used, for example, to set whether or not reception of BGM at a specific receiver is possible on the transmitting device side.

Further, in FIG. 4, reception I is performed on the receiver side.
The schematic diagram which shows the example which sets a different function (for example, volume switching) by D is shown. The function setting is not limited to the volume setting. In FIG. 4, when the call ID is an individual call, the volume is low, when the call is emergency, the volume is high, when the A group is called, the volume is medium, and when the B group is called, the volume is medium. It indicates that other settings are made when calling C group and n group.

As described above, a plurality of fixed IDs
By providing the receiver with the settable ID and the settable ID, the transmitting device can perform individual calls such as an individual call, an emergency call, and a group (group) call by sending only one ID. Therefore, the ID sending time for one call is short and the efficiency is high, which is particularly effective for increasing the scale. Further, it is possible to easily set the function in the receiver according to which kind of ID.

In this embodiment, since information can be transmitted by voice, all receivers can receive general broadcasts such as guide broadcasts and BGM broadcasts when they are not called. In order to receive the calling code while receiving, a transmitter and a receiving unit are usually required for each. Therefore, the cost and volume of the equipment are high. In order to solve these problems, a control signal for calling or the like is transmitted to a general broadcast signal such as a guide broadcast or BGM broadcast by using multiplex transmission such as time division or frequency division. One for each. This is effective for reducing equipment cost, volume, and the like. It is also effective for transmitting information in an emergency and for calling all at once.

In the transmitter shown in FIG. 1, BGM broadcasting,
An individual call ID code or a group ID call ID code, etc. are multiplexed by the main control device 38 and sent out by the control signal transmitter 55 for general broadcast such as guide broadcast and audio information broadcast in case of emergency. As described above, the other information is called I
The configuration is such that the D code and the like are multiplexed and transmitted, and then received.

Next, the conventional receiver has a sound source and a sounding body individually, and these two sounds are necessary for the ringing tone. There is no need for a sound source for each receiver, as the sound source is not required for each receiver, and the ringing tone can be produced only by the sounding body, which is effective in reducing cost and volume. Further, a switch is conventionally required to stop the ringing tone, but the example shown in FIG. 5 saves the switch and the trouble of operating the switch. In FIG.
Reference numeral 101 is a receiving unit, 102 is a voice switch, 103 is a sounding body, 104 is a calling ID code determination circuit, 105 is a flip-flop, and 106 is a light emitting body.

In the configuration as described above, the receiving section 101
The call ID code taken in from is compared with each ID set in the call ID code determination circuit 104, and only when they match, the voice switch 102 is connected, and the voice from the receiving unit 101 is generated by the sound generator 103. The flip-flop 105 is inverted and the light-emitting body 106 is turned on.

On the other hand, the transmitter side has a sound source for calling, sends a calling ID code, and then sends a ringing tone from the sound source. With this method, the sound source cannot be controlled from the receiver side, so it is effective for sending a ringing tone for a certain period of time. If the fact that there is a call is memorized and the light-emitting body 106 or the like is turned on, even if the above-mentioned ringing sound does not persist (on the contrary,
You do not need to stop ringing at the receiver side) You can check the call. Also, conventional devices do not carry large amounts of information and do not require multiple transmitters. However, in the case of transmitting a large amount of information as in the present embodiment, particularly when a plurality of transmitters are used, a plurality of input circuits are provided, and each individual use time is unspecified, the input circuit is used. By selectively connecting to a transmitter that is not active, one transmitter will be used more frequently, and less time will be spent resting. Therefore, the number of transmitters can be reduced. Also,
Congestion in information transmission can also be reduced.

An example is shown in FIG. 6 and will be described. In FIG. 6, 111 to 113 are p input circuits and 114 to 11
Reference numeral 6 is a q (p> q) transmitter, 117 is a connection circuit capable of connecting the p input circuits 111 to 113 and the q transmitters 114 to 116 in a grid pattern in an arbitrary combination. . Now, assuming that the input circuit 111 and the transmitter 114 are connected and used, the input circuit 112 and the transmitter 1 are used.
When 15 was connected and in use, the input circuit 111 and transmitter 114 were no longer in use and were disconnected. Subsequently, when the input circuit 113 requests connection, if the transmitter 114 that is now available is connected, it is not necessary to make the number of transmitters equal to the number of input circuits, and the number of transmitters 114 to 116 is reduced. Can be made.

Next, when it is intended that an unspecified number of people use a large number of receivers to make an unspecified number of individual calls, the calling number of the receiver (individual Associating an ID) with an individual becomes a difficult task. Moreover, it is a more complicated task when personal documents are involved. The above problem can be solved by configuring as follows.

For example, a physical printed individual code (bar code or the like) is attached to a receiver (sticking, printing,
By engraving, etc., the work related to calling the receiver can be simplified by associating it with the electrical code, physical code, personal name, personal code, other documents, etc. for determining that the receiver has been called. Can be converted. Figure 7
Shows a schematic diagram of an example thereof. In FIG. 7, reference numeral 121 denotes a receiver to which “12345” is assigned as a physical individual code and “6789” is set as an electrical individual code. Reference numeral 122 is a memory provided in the host computer 33 or the terminals 34a to 34d in FIG. 1, for example. 123 is a physical code reader connected to the memory 122, 124 is a manual code driver, 125 is a personal code reader, 126 and 127 are multiple calling devices (terminals, voice devices), and 128 is a transmitting device. is there.

The memory 122 stores a memory number (address), a physical individual code, an electrical individual code, a personal code, a document code, and another code in association with each other. It is desirable that the physical individual code and the electrical individual code of the receiver are the same, but when numbers, symbols, codes, etc. are mixed, it is often difficult for humans to read, and false call and malfunction occur. Etc. can be the cause. Therefore, the contents of the physical individual code and the contents of the electrical individual code do not have to be the same. Also,
In order to hand over an unspecified receiver to an unspecified number of people each time, and to save a great deal of effort to establish the relationship between the individual and the receiver, the following procedure is performed.

For example, "12345" is given as a physical individual code which is easy to read to the receiver and is easy to read, and the physical individual code "12345" is an electrical individual code "6789". The host computer 33 or the terminals 34a to 34d are associated with each other as a table. The physical individual code of the receiver is manually entered using the physical code reader 123 or the manual code driver 124. Then, the personal code is read by the personal code reader 124 or the manual code driver 1
Enter manually using 24. The host computer 33, such as a CPU, can now associate the receiver's physical individual code with the personal code.

Also, at this point, enter the document code etc.,
If they are associated with each other, the receiver can be called in various ways from the receiver's physical individual code, personal code, document code, and the like. As described above, by assigning a physical individual code to the receiver, it is possible to greatly reduce the effort for providing the relation between the individual and the receiver.

Below, the procedure of processing of the terminal as well as the transmitter and receiver for implementing the communication method of the present embodiment is shown in FIG.
25 to 26 and FIGS. 26 to 28. FIG. 8 shows an information processing apparatus and a large number of information processing apparatuses in which a host computer is installed in an office in a hospital, terminals are installed in a hospital reception, an examination room, a pharmacy, etc., and information is exchanged between the host computer and each terminal. A private branch exchange for exchanging telephones and a transmitter are connected, and a large number of receivers that receive the transmission signals of the transmitter are distributed to patients, staff, etc. in the hospital, and the terminal or host of the information processing device is connected. Use a computer or telephone to call specific patients or staff, nurses, etc., and give voice instructions, or call specific patients or staff, etc. in groups to give voice instructions, or all 9 is a flowchart showing a processing procedure of an information processing apparatus of a communication system for performing processing such as emergency broadcasting to patients and staff.

In this communication system, in the flow chart of FIG. 8, when the processing to be executed is the processing at the hospital reception, the terminal installed at the hospital reception is used to execute the processing shown in FIG.
The "reception process" is executed by the procedure shown in the flowchart.
If the processing to be executed is the processing of calling the receiver in the medical examination room of the hospital and the processing after calling the medical examination room, the terminal installed in the medical examination of the hospital is used and the flow chart of FIG. The "terminal calling process" is executed in the procedure as shown.

If the processing to be executed is processing of calling a receiver at an appropriate place in a hospital where terminals are not installed and only telephones are installed, such as a nurse center of a hospital, it is installed. Using the telephone set, the "telephone call process" is executed according to the procedure shown in the flowchart of FIG. If the process to be executed is the process after the examination in the hospital examination room, the terminal installed in the examination room of the hospital is used to perform "calling the terminal" according to the procedure shown in the flowchart of FIG. Execute processing.

When the process to be executed is the process at the time of medication in the pharmacy of the hospital, the terminal installed in the pharmacy of the hospital is used to perform the "pharmacy process" as shown in the flow chart of FIG. Execute. Further, the receiver collected at the pharmacy, for example, at the reception of the hospital, executes the “charging process” in the procedure as shown in the flowchart of FIG. 14 and uses it for the next use.

FIG. 9 is a flow chart showing a processing procedure for reception of a receiver handed to staff, nurses, patients, etc. in the communication system. The receiver executes the "reception process" in the procedure shown in the flowchart of FIG. 25 in the flowchart of FIG. Next, regarding "reception processing", "terminal calling processing", "telephone calling processing", "pharmacy processing", "charging processing" and "reception processing" in the receiver in the information processing device, telephone and transmitting device of the communication system The following is a detailed description with reference to the drawings.

First, the procedure of the "reception process" using the hospital reception terminal will be described with reference to FIG. First, it is determined whether or not the other party to whom the receiver should be handed over is a patient, and when the other party is the patient, the case of the receiver for which the “bar code reading process” is executed by the procedure shown in the flowchart of FIG. The individual ID of the receiver, which is given as a barcode on the outer surface, is read. The individual ID assigned to the receiver is, for example, a decimal number “128” to “409”.
4 ”is selected appropriately so that the same number is not used. This individual ID is mechanically set in the receiver so that it can be changed by a switch, etc., and the bar code indicating this individual ID is the case of the receiver. In addition, the same number or symbol as the individual ID or another number or symbol that has a predetermined correspondence with the individual ID is attached to the outer surface of the case to indicate the individual ID of the receiver. There are also cases.

Next, the "patient ID reading process" is executed in the procedure shown in the flowchart of FIG. 16 to read the patient ID. Next, it is judged whether or not the patient who should hand over the receiver is a member of the group, and if it is a member of the group, it is represented by, for example, a decimal number “3” to “126” (see FIG. 27).
Enter the group ID manually. If you are not a member of the organization, for example, "NUL" represented by the decimal number "4095"
L (meaning no group ID) "is automatically set.

Next, after handing over the receiver to the patient, the individual ID of the receiver is registered in the host computer (including the main storage device), and further associated with the individual ID, and the patient ID is sent to the host computer. Registration is performed, and the group ID of the patient who should hand over the receiver is set in the host computer. Next, the "group ID setting process" is executed in the procedure as shown in the flowchart of FIG. 17 to return to the original program shown in FIG.

On the other hand, it is judged whether or not the other party to whom the receiver is to be handed over is a patient, and if it is not a patient, the reception of staff etc. is performed.
"Bar code reading process" by the procedure as shown in the flow chart of 5
Is executed to read the individual ID of the receiver given by the barcode on the outer surface of the case of the receiver to be handed. Next, the "staff ID reading process" is performed by the procedure shown in the flowchart of FIG.
To read the staff ID. Then, when the staff ID indicates a nurse, for example, a group ID represented by a decimal number “0” (see FIG. 27) is set. Also, staff ID
Indicates a staff member, an organization ID represented by a decimal number "1" (see FIG. 27) is set. When the staff ID indicates other staff, it is represented by a decimal number “2” to “126” (see FIG. 27).
Set.

The group IDs indicating other groups overlap the number range of the group IDs indicating the groups of patients. This group ID is represented by decimal numbers "2" to "126".
(See FIG. 27) It means that the patient group and other groups are appropriately selected so as not to be the same. Also, in FIG. 27, decimal numbers “0” to “4095”
Although the number represented by is shown as an ID, the total number of assignable IDs is not limited to this and may be any number. Also, the individual I
It is not necessary to set D, the group ID, and the emergency ID as shown in FIG. 27, and they can be set to arbitrary numbers.

Next, after the receiver is handed over to the staff, the individual ID of the receiver is registered in the host computer (including the main storage device), the staff ID is registered in the host computer, and the receiver is further registered. The group ID of the staff to be handed is set in the host computer. Next, as in the case of the group ID set of the patient, the "group ID set process" is executed in the procedure shown in the flowchart of FIG. 17 and the process returns to the original program shown in FIG.

Secondly, the procedure of the "terminal calling process (including the examination ending process)" using the terminal in the examination room of the hospital will be described with reference to FIG. First, when the data indicating that the examination subject of the patient who came to the reception of the hospital is the examination subject of the examination room is sent from the reception terminal, the individual ID of the patient is fetched from the host computer 33, and then, The patient ID is fetched, and then the group ID is fetched.

Next, the address of the storage area of the patient ID in the main storage device of the host computer is set at the beginning, and the memory patient stored in the start address of the storage patient ID of the storage patient ID in the main storage device. If a match with the ID is detected, and if they do not match, the match detection between the fetched patient ID and the memory patient ID is continued while sequentially updating the address of the storage area for the patient ID in the main storage device. When the import patient ID and the memory patient ID match,
The medical record number or the like corresponding to the imported patient ID stored in the main memory of the host computer is imported to the terminal.
The memory patient ID and various information such as the chart number of the patient are stored in advance in the main storage device of the host computer in association with each other. If the patient ID is searched, various types of chart numbers and the like corresponding to the patient ID are stored. Information can be imported to the terminal.

Next, when the examination subject of the patient who came to the examination room of the hospital with the receiver is not the examination subject of this examination room,
In the case of the process of calling the receiver by the terminal, the "terminal broadcast process" is executed and the receiver is called, for example, in the procedure shown in the flowchart of FIG. On the other hand, when the process is not the call of the receiver but the process of ending the medical examination, the “medical examination ending process” is executed by the procedure shown in the flowchart of FIG. 20, and various information is sent to the terminal of the pharmacy. Back to the program
If it is not the process for ending the examination, the process returns to the beginning of FIG.

Thirdly, the procedure of "telephone call processing" using a hospital telephone will be described with reference to FIG. First, dial the telephone to call the transmitter,
Wait for a response from the transmitter. At this time, the transmitting device executes a "call process" as shown in FIG. In the telephone, when there is a response from the transmitter, the call ID (individual ID,
Dial the group ID and emergency ID). And
Waiting for the ringing to stop, and using the handset of the telephone as a microphone to speak the necessary requirements, broadcasting is performed, and when the broadcasting ends, a termination signal is sent and the original program shown in FIG. Return.

Fourthly, the procedure of "pharmacy processing" using the terminal of the pharmacy of the hospital will be described with reference to FIG.
First, it is judged whether there is pharmacy data sent from the terminal in the examination room, and if there is pharmacy data, the prescription is fetched from the host computer, then the individual ID is fetched, then the patient ID is fetched, and then the group ID. Take in and return to the beginning.

Here, the determination as to whether or not there is pharmacy data means to determine whether or not there is a data transmission (transfer) request from each examination room terminal. The pharmacy data refers to individual IDs, patient IDs, group IDs in FIG. 20, and also includes prescriptions when prescription data exists. By transferring these data to the pharmacy terminal, it means that the medical examination is completed. That is, regardless of the presence or absence of prescription data, each ID is transferred to the pharmacy terminal, and the pharmacy collects the receiver and the like. Further, the content of the prescription is used as the prescription data, and the medicine is not always provided to the patient even after the medical examination is completed, and thus the content of the prescription may not be provided. Therefore, the prescription and the prescription data are separately expressed. Although pharmacy data is basically transferred from the examination room terminal to the pharmacy terminal, the size of the system is large and small, and may be transmitted from the examination room terminal to the pharmacy terminal via the host computer. Conceivable.

On the other hand, if there is no pharmacy data, it is judged whether or not there is prescription data, a drug to be delivered to the patient is created based on the prescription data, and an individual ID is designated to call the patient to whom the drug is delivered. Then, the “terminal broadcasting process” as shown in FIG. 19 is executed to call the patient to whom the medicine is given. And
The receiver is collected from the patient who came to the pharmacy in response to the call, and the barcode attached to the collected receiver is read by executing the “barcode reading process” as shown in FIG. Detects the individual ID of the. Then, it is determined whether or not the read individual ID of the receiver matches the individual ID corresponding to the patient ID of the patient to whom the drug should be delivered, and if not, the patient who came to the pharmacy is different from the patient to whom the drug is to be delivered. As a result, the receiver is returned to the patient who came to the pharmacy. If there is a match, it is judged whether there is a drug to be passed, and if there is a drug to be passed, a drug is created and passed to the patient who came to the pharmacy to input a signal of completion, and if there is no drug to be passed For example, by inputting the completed signal as it is, each data (individual ID, group ID, patient ID) stored in the host computer or the like regarding the patient is canceled, and further the prescription is canceled to restore the original shown in FIG. Return to the program.

Fifth, the procedure of the "charging process" of the receiver will be described with reference to FIG. First, for the receiver that came back from the pharmacy, determine whether the group ID has been deleted. If the group ID has been deleted, set the receiver as it is in the charge box and if the group ID has not been deleted After clearing the group ID stored in the built-in RAM of the receiver, the receiver is set in the charge box, the built-in battery of the receiver is charged, and it waits until the next use.

The subprogram will be described below. First, the "bar code reading process" in the "reception process" of FIG. 10 will be described with reference to the flowchart of FIG. First, the information on the bar code provided on the outer surface of the case of the receiver is read, and it is determined whether the read bar code matches the individual ID.
Return to the original program indicated by 0.

If they do not match, the address of the bar code storage area of the host computer is set to the head address, and the read bar code and the registration code stored at the head address of the bar code storage area of the host computer are set. It is determined whether they match, and if they match, the individual ID stored corresponding to the registration code stored at the top address of the barcode storage area is read from the host computer and the terminal (in FIG. Terminal) to return to the original program shown in FIG.
If they do not match, the address of the bar code storage area of the host computer is updated to determine whether the read bar code matches the registration code, and the individual ID corresponding to the matching registration code is similarly sent to the terminal. If there is no matching registration code even when the end address of the barcode storage area of the host computer is reached, the "registration process" is executed because the individual ID corresponding to the barcode has not been registered.

In this "registration process", as shown in the latter half of the flow chart of FIG. 15, the reception terminal searches the free memory of the host computer, reads the bar code from the receiver, and registers it in the host computer. Then, the individual ID of the receiver is associated with the barcode and registered in the host computer. The above processing is performed for all unregistered receivers.

Secondly, the "patient ID reading process" in the "reception process" of FIG. 10 will be described with reference to the flowchart of FIG. First, it is determined whether the patient who came to the reception has a new patient, and if it is not a new patient, the patient I
The patient ID is read from the D card (for example, a medical examination ticket).
If the patient who came to the reception is a new patient, the patient ID
After creating the card, the patient ID is read from the patient ID card. Next, fill in the examination subject of the patient, and
Return to the original program indicated by 0.

Thirdly, the "group ID setting process" in the "reception process" of FIG. 10 will be described with reference to the flowchart of FIG. First, it is determined whether the group ID is "NULL". If the group ID is "NULL", the process directly returns to the original program shown in FIG. Group ID is "NULL"
If not, the host computer causes the transmitter to send the individual ID corresponding to the receiver to which the group ID should be set. At this time, the transmitting device executes a "call process" as shown in FIG.

Next, the control code (see FIG. 26) is sent from the host computer to the transmitter. Next, the host computer sends the audio device number specifying the audio device to be used to the transmitting device, and returns to the original program shown in FIG. Fourthly, the "staff ID reading process" in the "reception process" of FIG. 10 will be described with reference to the flowchart of FIG.

First, it is determined whether the staff member is a new staff member, and if the staff member is not a new staff member, the staff member ID card is read from the staff member ID card possessed by the staff member. If the staff is not a new staff, the staff ID is read from the staff ID card after the staff ID card is created. Then, the program returns to the original program shown in FIG. Fifthly, the "terminal broadcasting process" in the "terminal calling process" of FIG. 11 will be described with reference to the flowchart of FIG.

First, the calling ID corresponding to the called party is designated from the individual ID, the group ID and the emergency ID.
At this time, the transmitting device executes a "call process" as shown in FIG. Next, the designated call ID is sent to the transmitter. Then, the control code is sent to the transmitter. Then, the audio device number indicating the number of the audio device to be used is sent to the transmitting device.

Next, it is judged whether the broadcast content is a fixed sentence. If it is a fixed sentence, one of a plurality of fixed phrases is designated, and the voice is waited for until the ringing tone stops. Broadcast audio by synthesis or magnetic tape, and when the broadcast ends, send a broadcast end signal and return to the original program shown in FIG. On the other hand, if it is not a fixed sentence, the transmitter and the receiver are turned on, the ringing tone is confirmed, and after the ringing tone is stopped, the voice is broadcast, and when the broadcast is finished, a broadcast end signal is sent and Return to the original program shown.

The above ringing tone is generated by the main controller 3 of the transmitter.
8 signal sound output terminals to hybrid circuits 41a to 41
It is sent to the receiver side and the audio device side through c, 42, 46a and 46b. Therefore, on the fixed phrase side of FIG.
The judgment of stoppage of the ringing sound is made mechanically and the broadcast of the fixed phrase is started. Usually, a recording tape or a voice synthesizer is used for the fixed phrase, and the end signal is output at the end of the fixed phrase, that is, at the end of broadcasting. Specifically, a fixed sentence is recorded, and then an end signal is recorded to form one fixed sentence.

In the real voice broadcast, a human makes all the judgments, confirms by ear that the ringing sound heard from the receiver is stopped, and then the broadcast is started via the transmitter. Therefore, a person determines the end of the broadcast, and the end signal is transmitted manually. Sixth, the "examination termination process" in the "terminal calling process" of FIG. 11 will be described with reference to the flowchart of FIG.

First, the end of consultation is designated, it is judged whether or not there is a prescription, and if there is no prescription, the individual ID of the receiver corresponding to the patient for which the consultation is completed is sent to the terminal of the pharmacy, and if there is a prescription. Creates prescription data, sets no prescription data if there is no prescription, then sends the prescription to the terminal of the pharmacy, and further sends the individual ID of the receiver corresponding to the patient who completed the examination to the terminal. Then, the patient ID is sent to the terminal of the pharmacy, then the group ID is sent, and the individual ID of the receiver, the patient ID, and the group stored in the memory of the own terminal in the examination room and corresponding to the patient who has finished the examination. The ID and the like are canceled, and the process returns to the original program shown in FIG.

Seventh, "Telephone call processing" in FIG.
The "calling process" in the "group ID setting process" of FIG. 17 and the "terminal broadcasting process" of FIG. 19 will be described with reference to the flowchart of FIG. First, it is determined whether or not the call has arrived at the line control unit (network control unit, NCU).

If the call is not received by the line control device, the call ID (individual ID) is fetched, then the control code is fetched, the voice device number is fetched, and then, for example, whether the eighth bit of the control code is "1" or not. And the 8th bit is "1", the call ID
The (individual ID) is sent to the signal sending buffer, the control code is also sent to the signal sending buffer, the signal sending flag is raised, and the "signal sending process" as shown in the flowchart of FIG. 22 is executed. Then, it is determined whether or not the signal transmission flag has been lowered, and after waiting for the signal transmission flag to be lowered, the original program shown in FIG. 12 or 19 is returned to.

On the other hand, if, for example, the 8th bit of the control code is not "1", it is determined whether or not there is a free transmitter by a flag. If there is a free transmitter, the flag of the free transmitter is activated. , The transmitter number is sent to the signaling buffer, and then the calling ID is sent to the signaling buffer. If there is no transmitter available, the calling ID is emergency I.
If it is not the emergency ID, the process returns to the determination of the idle transmitter, and if it is the emergency ID, the calling ID is sent to the signal transmission buffer.
After transmitting the call ID to the signal transmission buffer, the voice device number is transmitted to the signal transmission buffer, then the signal transmission flag is raised, and the "signal transmission process" shown in the flow chart of FIG. 22 is executed. After that, it is determined whether the call ID is an emergency ID. If the call ID is an emergency ID, the volume is set to a high level, and then the "emergency broadcast process" as shown in the flowchart of FIG. , Return to the original program shown in FIG. 17 or FIG. 19, and if the call ID is not the emergency ID, set the volume to low and then execute the “broadcast process” shown in the flowchart of FIG. 12 and 17
Alternatively, the process returns to the original program shown in FIG.

Next, in the case of an incoming call from the line control device, a response to the incoming call is made and it is judged whether or not a time-out has occurred.
And then set the line control device number as the voice device number. Then, it is determined whether there is a free transmitter by the flag. If there is a free transmitter, the flag of the free transmitter is activated, the transmitter number is sent to the signal sending buffer, and then the call ID is sent. If there is no idle transmitter, the call ID is determined whether it is an emergency ID. If it is not an emergency ID, the process returns to the determination of an idle transmitter, and if it is an emergency ID, the call ID is used.
22 is sent to the signal sending buffer, and in any case, after the calling ID is sent to the signal sending buffer, the voice device number is sent to the signal sending buffer, and then the signal sending flag is raised, as shown in FIG. The "signal transmission process" as shown in the flow chart is executed, then it is determined whether or not the call ID is the emergency ID, and if it is the emergency ID, the volume is set to a high level, and then the flow chart shown in FIG. 23, after returning to the original program shown in FIG. 12, FIG. 17, or FIG. 19, if the call ID is not the emergency ID, the volume is set to a low level, and then FIG. The "broadcast process" shown in the flowchart of FIG. 12 is executed to return to the original program shown in FIG. 12, FIG. 17 or FIG.

If the time-out occurs, it means that the telephone is erroneously connected, and the process returns to the original program shown in FIG. 12, FIG. 17 or FIG. Eighth, the "signal transmission processing" in the "call processing" of FIG. 21 will be described with reference to the flowchart of FIG. 22 and the table showing the contents of the signal transmission buffer of FIG.

First, it is determined whether or not the signal transmission flag has risen, and when the signal transmission flag has risen, after waiting for the receiver processing time, the synchronization signal (SY
N) is sent, then a heading is sent, then a control code is sent, then an ID code indicating an individual ID is sent, then an end of text is sent, and then a signal transmission flag is turned off.

The signal transmission buffer shown in FIG. 28 uses, for example, a 7-bit control code, a 12-bit ID code, a 7-bit audio device number, and a signal transmission flag as one set of data, and stores these data. A plurality of sets can be stored, and the "signal transmission process" in FIG. 22 is repeated until all the signal transmission flags in the signal transmission buffer fall.

Ninth, the "broadcast process" and "emergency broadcast process" in the "call process" of FIG. 21 will be described with reference to FIG. First, the "broadcast process" will be described. It is determined whether or not the signal transmission flag has fallen, and when the signal transmission flag has fallen, the transmitter with the signal transmission flag lowered and the voice device are connected, and then a ringing tone is output, for example, 5 It is determined whether or not a second has elapsed, and when 5 seconds have elapsed, the ringing tone is stopped, and then the "broadcast end processing" shown in the flowchart of FIG. 24 is executed. This "broadcast end process" continues until the transmitter flag is turned off. When the transmitter flag falls, it waits n seconds (may be several milliseconds), disconnects the transmitter from which the transmitter flag was lowered and the audio device, and returns to the original program shown in FIG.

Even when the above 5 seconds have not elapsed,
The "broadcast end process" as shown in the flowchart of FIG. 24 is executed. After this, it is determined whether the transmitter flag has been turned off, and if the transmitter flag has not been turned off,
Returning to the determination as to whether or not 5 seconds have elapsed, when the transmitter flag is turned off, wait for n seconds (it may be several milliseconds) and wait for the transmitter and voice device that turned off the transmitter flag. Is separated, and the program returns to the original program shown in FIG.

Next, the "emergency broadcast process" will be described. First, when a predetermined voice device is connected to the BGM input, then all transmitters are connected to the above voice device, and then a ringing tone is emitted, for example, it is determined whether 5 seconds have passed, and when 5 seconds have passed Then, the ringing tone is stopped, and then the "broadcast end process" as shown in the flowchart of FIG. 24 is executed. This "broadcast end process" continues until the transmitter flag is turned off. When the transmitter flag falls, it waits n seconds (may be several milliseconds), disconnects the transmitter from which the transmitter flag was lowered and the audio device, and returns to the original program shown in FIG.

Even when the above 5 seconds have not elapsed,
The "broadcast end process" as shown in the flowchart of FIG. 24 is executed. After this, it is determined whether the transmitter flag has been turned off, and if the transmitter flag has not been turned off,
Returning to the determination as to whether or not 5 seconds have elapsed, when the transmitter flag is turned off, wait for n seconds (it may be several milliseconds) and wait for the transmitter and voice device that turned off the transmitter flag. Is separated, and the program returns to the original program shown in FIG.

Tenth, the "broadcast processing" and the "emergency broadcast processing" of FIG.
This will be described with reference to FIG. First, it is determined whether or not there is an end signal, and if there is an end signal, the transmitter flag is turned off, and the program returns to the program shown in the flowchart of FIG. If there is no end signal, a timeout (1-
After about 2 minutes), if it times out, output the end signal, then turn off the transmitter flag,
If the time-out has not occurred, the program directly returns to the program shown in the flowchart of FIG.

Next, the "reception processing" in the receiver will be described with reference to FIG. First, it is determined whether or not the sync signal (SYNC) is input. When the sync signal is input, the heading is fetched and the text (code) is fetched in the buffer. This text inclusion is repeated until the end of text is entered. After that, the ID code in the text is the individual ID of your machine.
When the two match, it is determined whether the 8th bit of the control code is "1" or "H", and the 8th bit is "1" or "H". When it is ", the data of the first to seventh bits of the control code (group I
D) is stored in RAM (random access memory),
Return to the beginning. The 8th bit of the control code is "1"
Alternatively, when it is not "H", the receiving channel is shifted from the control signal channel to the audio broadcasting channel indicated by the data of the first to seventh bits of the control code, the audio circuit is turned on, and the light emitting diode for display is displayed. Flicker.

For example, it is determined whether or not 5 seconds have passed since the flicker of the light emitting diode was started. If 5 seconds have passed, the light emitting diode is turned off, it is determined whether there is an end signal, and the end signal is input. The audio circuit is turned off after being waited for, and then the reception channel is returned to the control signal channel, and the operation is returned to the beginning. After the flicker of the light emitting diode,
Even before 5 seconds have elapsed, it is determined whether the end signal is input, and if the end signal is not input, the process returns to the determination whether 5 seconds have elapsed, and the end is performed before 5 seconds have elapsed. When a signal is input, the light emitting diode is turned off, the audio circuit is turned off, and then the reception channel is returned to the control signal channel, and the flow returns to the beginning.

On the other hand, if the individual IDs do not match, then the ID code in the text is the group ID stored in RAM.
If the two match, the receiving channel is shifted from the control signal channel to the audio broadcasting channel indicated by the 1st to 7th bits of the control code, and the audio circuit Is turned on, and the light emitting diode for display flickers.

For example, it is determined whether 5 seconds have passed since the flicker of the light emitting diode was started. If 5 seconds have passed, the light emitting diode is turned off, it is determined whether there is an end signal, and the end signal is input. The audio circuit is turned off after being waited for, and then the reception channel is returned to the control signal channel, and the operation is returned to the beginning. After the flicker of the light emitting diode,
Even before 5 seconds have elapsed, it is determined whether the end signal is input, and if the end signal is not input, the process returns to the determination whether 5 seconds have elapsed, and the end is performed before 5 seconds have elapsed. When a signal is input, the light emitting diode is turned off, the audio circuit is turned off, and then the reception channel is returned to the control signal channel, and the flow returns to the beginning.

If the group IDs do not match, then it is determined whether the ID code in the text matches the emergency code stored in the ROM (Read Only Memory). If they match, then Turn on the voice circuit,
Flicker the light emitting diode for display. For example, it is determined whether 5 seconds have passed since the flicker of the light emitting diode was started. If 5 seconds have passed, the light emitting diode is turned off, it is determined whether there is an end signal, and the end signal is input. The audio circuit is turned off after waiting for, and then the reception channel is returned to the control signal channel, and the operation returns to the beginning.
After the flicker of the light emitting diode, it is determined whether or not the end signal is input even before 5 seconds have passed. If the end signal is not input, the process returns to the determination whether 5 seconds has passed and 5 seconds have passed. If the end signal is input before the time elapses, the light emitting diode is turned off, the audio circuit is turned off, and then the reception channel is returned to the control signal channel (at this time, the reception channel remains the control signal channel. Yes, go back to the beginning.

If the emergency IDs also do not match, BG
Determine whether the M switch is (OFF),
If it is (off), it returns to the beginning, and if it is not (off), it receives BGM and returns to the beginning. Next, when the sync signal (SYNC) is not input, it is determined whether or not the BGM switch is (OFF), and (OFF)
If it is, it returns to the beginning, and if it is not (off), it receives BGM and returns to the beginning.
