Abstract

<P>PROBLEM TO BE SOLVED: To avoid confusion in operation when setting is permitted, even from the outside of a receiver body. <P>SOLUTION: A signal transmitting/receiving method includes a local mode being a setting mode at the side of the receiver body; and a remote mode by a remote signal from an outer part. The setting processing by the remote signal is prevented in principle, in the case of a local mode, and the setting processing in the local mode is prevented in the case of a remote mode. Thus, when the mode is changed-over into the local mode, the remote mode is prevented, when the menu is selected by a key operation at the side of the receiver and the setting value of the selected menu is decided. Even when the remote signal is inputted from terminal equipment, this can be excluded. When the mode is changed-over into the remote mode, a reverse processing is performed. That is, key input is prevented, even when keys are operated in the receiver, and the key operation become invalid. Thus, the confusion is avoided in the setting operation. <P>COPYRIGHT: (C)2004,JPO

2. Description of the Related Art A plurality of microphones, especially a wireless microphone, are often used for collecting sounds used for recording in a studio or an outdoor studio of a broadcasting station.
The signal transmitted from these wireless microphones is received by a receiver, demodulated, and then recorded in a recording device to construct a receiving system. Further, in order to manage the states of a plurality of wireless microphones, a terminal device for management is connected to construct a centralized management system for the receiver as a whole.

FIG. 22 shows a central control system 1 for this receiver.
0 is a specific example, and each transmission signal from the plurality of wireless microphones 12 (12A, 12B, ...) Used in the studio is a single or a plurality of antennas, in this example, two antennas. The signals received by 14A and 14B are demodulated in the receiver 20 respectively. Here, the transmission frequency used for each wireless microphone 12 is different. The demodulated audio signals for the respective wireless microphones 12 are mixed in the mixer 22. The mixed audio signal is output as it is and supplied to a signal transmission unit (a signal transmission unit for television broadcasting or radio broadcasting) (not shown), and in some cases, a recording device such as a digital audio tape recorder (DAT). Will be recorded using.

The receiver 20 is further connected to a terminal device 30 by a communication cable 24 such as RS-232C. A personal computer or the like can be used as the terminal device 30, and information regarding the wireless microphone 12 is displayed on the monitor 30a thereof. The information regarding the wireless microphone 12 is the reception state (level, etc.) of the receiver 20, the audio output level to the mixer 22, or the battery level when the wireless microphone 12 is driven by a battery (battery). Related information, etc.

By displaying such information on the monitor 30a, the microphone reception state and the like can be grasped, so that the terminal device 30 can centrally manage the usage status of the wireless microphone 12 in the studio and the plurality of receivers 20.

It is also possible to control the receiver 20 from the terminal device 30 side. For example, when setting or changing the reception frequency from the wireless microphone 12 as described below,
The value can be set or changed from the terminal device 30 side.

In such a centralized management system for receivers, the main body of the receiver can also perform various menu setting processing and the like. By doing so, the receiver itself can perform menu selection and determination processing, and even if the terminal device is located at a place distant from the receiver main body, the receiver main body can be operated remotely. It is very convenient.

Data communication between the receiver 20 and the terminal device 30 is carried out by TCP / IP (Transmission Control Protocol).
col / Internet Protocol), that is, when data communication is performed between the transmission source, for example, the receiver 20 and the terminal device 30 that is the reception source, the line connection (connect process) is performed first. After this, the packetized data transfer process starts.

[0010]

By the way, if the menu selection and the setting process can be executed on both the receiver 20 side and the terminal device 30 side as described above, the operator receives the receiver 2
It is very convenient because setting operations such as menus can be performed on either the 0 side or near the terminal device 30.

For example, if menu setting and selection can be performed only on the receiver 20 side, it is inconvenient because the user must go to the studio where the receiver is set to perform the setting work. However, as described above, if the remote control can be performed from the terminal device 30 in addition to the receiver 20, there is an advantage that the setting work can be performed quickly.

[0012] However, if setting is possible on both sides in this way, the following problems also occur. For example, select the menu on the receiver side and perform setting processing (called local mode)
When executing, the related person who does not know that the setting work is executed may operate the same receiver 20 from the terminal device 30 at the same timing. Then, the batting of the setting process occurs, and the items that have already been set may be changed.

On the contrary, while the terminal device 30 is used to remotely operate the receiver main body, a person involved in the studio receives the message while selecting a menu and performing setting processing (called remote mode). It is conceivable to operate the machine 20, and even in this case, it is not possible to prevent double setting work,
Get confused.

Therefore, the present invention solves such a conventional problem, and in particular, both sides can be set and the setting modes can be switched so that one side executes the setting process. In the meantime, the present invention proposes a signal transmission / reception method, a receiver, and a centralized management system for the receiver, which can prevent the setting process on the other side from being disturbed so as to avoid confusion of the setting operation.

[0015]

In order to solve the above-mentioned problems, in the signal transmitting / receiving method according to the present invention described in claim 1, a plurality of setting menus and setting values can be selected and determined locally on the main body side. The mode and the remote mode where the setting menu and setting values can be selected and determined by an external remote signal are switched and used.When the local mode is selected, the setting value of the remote signal It is characterized in that the decision processing is prohibited.

In the receiver according to the present invention described in claim 5, a signal receiving unit, a data communication unit capable of communicating with the outside, a local mode capable of selecting and determining the setting menu and setting values on the main body side, and an external unit And a mode selection means for switching between a remote mode capable of selecting and deciding the setting menu and the setting value by a remote signal from.

In the receiver centralized control system according to the present invention described in claim 8, a receiver for outputting a signal related to a received signal and a remote signal for selecting and deciding a menu item of the receiver. And a terminal device having a monitor for receiving and displaying a signal related to the received signal as monitoring data, and in the receiver, the setting menu and setting values can be selected and determined on the main body side. The local mode and a remote mode in which the setting menu and setting values can be selected and determined by a remote signal from the outside are switched, and when the remote mode is selected, the setting menu and the Allows setting values to be selected and determined, and the contents displayed on the monitor together with information related to the received signal. Characterized in that to allow the middle management.

When the setting mode in which the setting process is performed on the receiver body side is the local mode and the setting mode on the terminal device side is the remote mode, the setting modes can be switched according to the present invention. The signal processing from other setting modes is prohibited.

For example, when switching to the local mode and selecting a menu by the key operation on the receiver side or determining the setting value of the selected menu, the remote mode is prohibited and the remote signal is transmitted from the terminal device side. Eliminate this even if you enter it. By doing so, menu setting processing and the like can be performed without being aware of the remote signal.

When switching to the remote mode, the operation is the reverse of that described above, and even if an attempt is made to operate a key on the receiver side, key input is prohibited and the key operation is invalidated. By doing this, it is possible to avoid confusion in the setting operation.

A key for switching between the remote mode and the local mode is provided on the receiver side, and the key operation is monitored by the control unit (CPU) of the receiver body. When there is a key operation, the mode selection is executed. By this switching, for example, when the mode is switched to the local mode, the indicator lights to inform that the mode is switched to the local mode. In the local mode, the lighting process was performed because the person involved in the operation is in front of the receiver in the local mode, and it is easier for the person concerned to recognize the setting mode state by displaying the light. is there.

When the receiver is set to the local mode, the remote mode prevents the receiver from being operated remotely. Even in that case, the receiver must be operated. In such a case, the local mode is forcibly switched to the remote mode. At this time, since it is a special operation, a password registered in advance is used. By authenticating this password on the receiver side, when it is confirmed that it is the same as the registered person, the switching in the remote mode is permitted for the first time. This makes it possible to avoid operational mistakes.

In the receiver centralized control system according to the present invention, a receiver having a local mode and a remote mode as setting modes, a remote signal is sent to the receiver, and various monitoring data from the receiver is sent. With a terminal device for monitoring and display that can receive and display this,
When the remote mode is selected, the setting processing can be executed by the remote signal, and its contents and the monitoring data can be displayed.

In this way, in addition to the feature that various menu settings can be remotely controlled even for the receiver installed at a place distant from the terminal device, the wireless microphone including the state of the received signal to the receiver is included. The battery level and audio output level of can be monitored at the same time.

Further, when the number of wireless microphones that can be handled by the receiver is large and the receivers are cascade-connected, it is necessary to monitor a large number of states. According to the present invention, the terminal device is centrally managed. This makes it easier to monitor and manage wireless microphones.

[0026]

BEST MODE FOR CARRYING OUT THE INVENTION Next, one embodiment of a signal transmitting / receiving method, a receiver and a centralized management system for this receiver according to the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an embodiment in which a centralized control system 40 for a receiver according to the present invention, to which the signal transmitting / receiving method and the receiver according to the present invention are applied, is applied to a reception management system for a studio wireless microphone. It is a connection diagram.

Composed of.

In the studio, a plurality of wireless microphones 1
2 (12A, 12B, ...) Is used. When using a plurality of microphones, the transmission frequency of each wireless microphone 12 is determined so as not to interfere with each other. Usually, the transmission frequency groups that do not cause mutual interference are grouped. The transmission frequency is the band (797 to 806) assigned to the land mobile station of the specific radio microphone.
(MHz band) and the UHF band frequency included in the band (806 to 810 MHz) allocated to the specific low power radio station are used, and channels are allocated in 0.125 MHz increments.

FIG. 2 shows an example of the relationship between the transmission frequencies grouped as frequencies that do not affect each other and the group GP and the channel number CH assigned to that frequency. This grouping, the number of channels that can be used in the group, and the frequencies to be used are used only for the purpose of explaining the present invention, and are not limited to this example.

Receiving antenna 1 corresponding to this transmission frequency
4 is attached to the ceiling in the studio or the appropriate studio side wall. In this example, since the diversity reception system is adopted as described later, the two reception antennas 14A and 14B attached at appropriate intervals are used to receive the transmission signals from the plurality of wireless microphones 12. In this example, the wireless microphone 12 is driven by a battery in addition to the collected voice signal as the transmission signal, so that a signal indicating the battery level is also superimposed on the voice signal and transmitted.

The signals received by the receiving antennas 14A and 14B are guided to the receiver 20 by the coaxial cables 16a and 16b. In this example, a plurality of receivers 20 are cascade-connected, but this is common when the number of wireless microphones 12 used in one studio is large or when the wireless microphones 12 used in adjacent studios are common. This is an example of connection applicable to the case where reception is performed by the receiving antennas 14A and 14B.

The number of wireless microphones 12 that can be received by one receiver 20 is arbitrary, but in the example described below, a maximum of four wireless microphones 12, and therefore four transmission signals of different frequencies, can be received. The case is shown.

Therefore, as shown in FIG. 1, one coaxial cable 16a is provided on the rear panel 1 of the first receiver 20A.
It is connected to the cascade input terminal 43a of the antenna distributor 42A provided in 7a. The cable (BNC cable) connected to the output terminal 43b is similarly cascade-connected to the input terminal 43a of the antenna distributor 42B provided on the rear panel 17b of the second receiver 20B.

Similarly, the other coaxial cable 16b is connected to the input terminal 45a provided on the antenna distributor 44A of the rear panel 17a, and the output terminal 45b is also provided.
Will be cascaded to the input terminal 45a of the next receiver 20B.

The received signal is demodulated internally, and the demodulated signal (a signal of up to 4 channels) is supplied to the mixer 22 via the XLR cable 46A. In this embodiment, a recording device 26 such as a DAT is connected to the mixer 22, and demodulated signals of up to 16 channels obtained by the respective receivers 20A to 29D are supplied to the mixer 22 via the XLR cables 46A to 46D. When they are played, they are mixed and recorded. The mixer 22 is also provided with an output terminal 23, and in the case of simultaneous broadcasting or the like, the signal is supplied to the signal transmitting section (not shown) together with the video signal as described above.

The plurality of receivers 20A to 20D and the above-mentioned terminal device 30 are connected to each other via a local area network LAN. In this example, the high speed communication cable 48
And a hub (HUB) 49 form a LAN. In this example, a 10BASE-T category 5 cable is used as the high-speed communication cable.

Therefore, a plurality of receivers 20A-20D
A signal (management data such as monitoring data) related to the received signal obtained is connected to the hub 49 via the high-speed communication cables 48A to 48D, and the hub 49 is also connected to the terminal device 30 by the high-speed communication cable 48E. ing.

When a high-speed communication cable 48 such as 10BASE-T is used, high-speed communication with a transfer rate of about 10 Mbits per second can be achieved. Therefore, high-speed processing is possible, and by using the hub 49, 100 m It is possible to secure a sufficient communication quality and transfer speed even if the length is set.
As a result, the installation location of the terminal device 30 is not restricted.

The signal related to the received signal is a signal indicating the level of the battery used in the wireless microphone 12, and a signal indicating the received signal level (high frequency signal level (RF level)) from each of the receiving antennas 14A and 14B. , Audio output level (AF level) to be sent to the mixer 22, and the like. The signal related to this received signal is used as monitoring data for the receiving antenna and the receiver itself, and is transmitted in response to a request from the terminal device 30.

The terminal device 30 is used as a data management terminal using a personal computer as described above, and management information is displayed on the monitor 30a thereof. The management information is managed for each receiver 20 described above, and if the management information for a specific receiver can be displayed,
The management information of all the receivers can be divided and displayed on the same monitor screen. The display mode is arbitrary.

In addition to the above-mentioned monitoring data, the contents displayed as the management information include the identification number assigned to each receiver, the reception frequency, the group name and channel number of the wireless microphone used. Wireless microphone 1
The channel number 2 and therefore its transmission frequency and the like can be set or changed from the terminal device 30 side.

FIG. 3 shows a configuration example of the front panel of one receiver 20. The figure shows a configuration example of the front panel 51A of the receiver 20A, in which a voice monitor terminal PHN is provided next to the power switch SW, an earphone is inserted, and the volume VR is adjusted to output the voice of the specific wireless microphone 12. I can listen. Of course, it is possible to listen to the sound collected by all the wireless microphones 12 received by each of the receivers 20, or to mix and listen to the specific wireless microphones 12.

A display unit 53 is located next to it. The display unit 53 is a two-line upper and lower line display due to space limitations.
The number of characters in a line is small, and in the example shown in the figure, it is about 16 characters in alphabed notation. Since the number of display lines and the number of display characters are small in this way, the display unit 53 completes the display contents in one line display, and does not employ a display method of scrolling vertically and horizontally. for that reason,
On the display unit 53, a setting menu and the like are displayed with abbreviated symbols as much as possible, and hierarchical display is performed. One setting menu is constructed by a plurality of layers, and each layer is completely displayed in one line.

The upper part is a menu title display section 53a. For example, local mode and remote mode are written in English. Here, the local mode is a mode in which various settings can be made on the receiver 20A side, and the remote mode is a mode that can be set from the terminal device 30 side.

The lower part is a display section 53 for displaying menu items and setting values.
b, and showing an example of a hierarchical structure of menu items,
There are the following. The top-level menu (first layer) is a root menu, and selectable menu items (for example, four items) are displayed in abbreviated symbols. When a menu item is selected, a submenu (second layer) is displayed, and then a submenu. The item (for example, 4 items) displayed on the lower 5
By the procedure of selecting from 3b, the process proceeds to the lower hierarchy. A specific example will be described later.

Next to the display section 53, the front panel 51
An operation key group 52 is provided substantially at the center of A.
In this example, consideration is given to reducing the number of operation keys as much as possible, the menu key 54 displays the above-mentioned menu, and the left and right shift keys 5 indicated by arrows.
5 is used when selecting a menu item or setting value of the setting menu, and the result is confirmed by the enter key 56. The + and-shift keys 57 are used when changing the setting value of the setting menu in the local mode.

An operation key 58 for switching between the local mode and the remote mode is provided, and the indicator 59 lights up when the local mode is selected. With this, the mode switching can be easily recognized.

Next to the operation key group 52, a receiving section 60A for receiving signals is provided. The receiver 60A is the receiver 20
It is provided in correspondence with the number of the wireless microphones 12 that can be handled by A. In this example, four receiving units 60Aa whose receiving frequencies are set to the transmitting frequencies f1a to f1d of the wireless microphones 12 to be used. ~ 6
It is equipped with 0Ad.

The receiving sections 60Aa to 60Ad are provided with setting display sections 61Aa to 61Ad, and although not shown here, the group GP of the wireless microphones 12 and the channel CH are displayed and the receiving antennas 14A and 14B are also displayed.
The higher reception level (RF level), audio output level (AF level), or the battery level of the wireless microphone 12 is displayed in this example. However, the battery level is displayed from 1 hour before charging.
This allows you to know when to charge the battery or know when it is time to replace it. Further, when the reception frequency is changed by the UHF synthesizer, the value is displayed, and the setting display unit 61
The state of the wireless microphone 12 and the like can be grasped only by looking at Aa to 61Ad.

FIG. 4 shows the circuit configuration of the receiver 20 described above. In FIG. 4, a CPU 71 controls the entire receiver, and its system bus 78 is connected with various circuit blocks as described below. First, the signal received by one of the receiving antennas 14A is divided into 5 in this example by the distributor 42A, the received signals divided into 4 are supplied to the corresponding receiving units 60Aa to 60Ad, and the remaining received signals are cascade output terminals. 43b is supplied. Four
The receiving units 60Aa to 60Ad of the stand are connected to the system bus 78. The signal received by the other receiving antenna 14B is also supplied to the other distributor 44A, and similarly the four receiving units 6
0Aa to 60Ad and distributed to the cascade output terminal 45b. The configurations and operations of the receiving units 60Aa to 60Ad will be described later.

A microphone output circuit 72 is connected to the system bus 78 described above, and the audio output from the receivers 60Aa-60Ad passes through the microphone output circuit 72 and the external terminal 21.
It is output to the A side. In the data communication unit 73, mutual data communication is performed via a high speed communication cable connected to the terminal jack 47A.

A program storing ROM 74 is further connected to the above-mentioned system bus 78, and a control program (processing program) necessary for controlling the receiver main body, control of the receiver main body itself (setting processing system) are connected here. ), The control between the receiver main body and the receiving units 60Aa to 60Ad, the communication control with the terminal device 30, and the like are performed.
Such control processing is performed by working memory (RAM, etc.)
75 is used.

When performing data communication between the above-mentioned receiving units 60Aa-60Ad and the receiver main body, the receiving units 60Aa-6
In consideration of the difference in data processing speed between the CPU (block CPU) 86 built in 0Ad and the main body CPU 71, the system bus 78 has a pair of buffer memories (RA).
M, etc.) 76, 77, 79 are provided.

The buffer memories 76 and 77 are used for synchronous and asynchronous communication, and the other buffer memory 7 is used.
9 is used as a memory means or the like when temporarily storing packetized data. The details will be described later. The system bus 78 is further connected to the key input section 80 and the display section 81 (30a) described above. The display unit (screen display unit) 81 is provided with a graphic user interface (GUI) 82 in order to realize the graphic display as shown in FIG.

Since the receiving units 60Aa to 60Ad described above have the same configuration, the receiving unit 60Aa will be outlined below. The receiving unit 60Aa has a signal processing unit 85 including a diversity receiving unit. Among the signals of the same frequency received by the reception antennas 14A and 14B, the reception frequency f1a associated with the wireless microphone 12A, which is assigned to the reception unit 60Aa, is selected, and the input level of the selected reception signal ( Of the RF levels), the higher level is always selected. In other words, this diversity receiving section is, in this example, a spatial diversity method and a signal switching method.

As will be described later, the signal processing section 85 is provided with a frequency setting means (not shown) of a PLL synthesizer system for setting a reception frequency, a demodulation circuit, a variable amplification circuit and the like, and a reception level (RF Level),
A signal processing system that outputs a sound output level (AF level) from the variable amplifier circuit is provided.

The block block CPU 8 for setting the reception frequency and communicating with the receiver body.
6, a memory that stores programs for executing various controls and processes in the receiving unit 60Aa,
A memory means 87 including a working memory and the like is built in. All of these are connected to the system bus 78 described above.

FIG. 5 shows a circuit block configuration example on the terminal device 30 side. The terminal device 30 functions as a personal computer, and as is well known, includes a program storage memory (ROM or the like) 92 and a working memory (RAM or the like) 93, and a key input section 94.
The monitor 95 and the monitor 95 are connected to the system bus 98, and the data communication means 9 is used to communicate with the outside.
6 and a buffer memory 97 for transmission / reception used in connection therewith are connected to the system bus 98 to construct the terminal device 30.

Here, the processing speeds of the block CPU 86 built in the receivers 60Aa to 60Ad and the main body CPU 71 built in the main body of the receiver are generally different from each other. In this embodiment, the processing speed is different. For this reason, a processing speed of the block CPU 86 is faster than that of the main body CPU 71. Incidentally, in the present example, the former processing speed is 5 msec per cycle, whereas the latter processing speed is 50 msec per cycle.

When performing data communication between the receiver 20 and the terminal device 30 used for data monitoring and management, the data to be transmitted from the receiver 20 is the minimum data transfer unit. The data to be transmitted is processed so that it fits within the packet size. When the packet size of the minimum transfer unit is, for example, 128 kbytes, transfer data (hereinafter referred to as packet data) is processed so that one transfer data unit is equal to or smaller than this packet size.

Then, as shown in FIG. 6, a header, an IP address such as a port number, a TCP header, etc. are added to the packet data so that the packet data has a data structure conforming to the TCP / IP protocol. . This data transfer format is sent to the high speed communication cable 48.

The data structure of packet data differs depending on the type of data to be transferred. FIG. 7 is a data structure showing an example thereof. In this example, the data is transferred collectively for each receiving unit, and four receiving units 60A as shown in FIG.
When the receiver 60A is configured with a to 60Ad, it can be configured as four continuous data blocks 100a to 100d.

In this example, two receiving antennas 14A,
The reception level (R
Monitoring data (RFA) 1, (RFB) indicating F level)
1 and monitoring data (A
F) 1 and monitoring data (BAT) 1 indicating the battery level of the wireless microphone 12A are respectively inserted to form a data block 100a.

Since all the monitoring data can be reproduced without fail by using only the data inserted in the data block 100a, the data is completed only by the data in the data block. That is, 1
The data structure does not need to use a plurality of packet data transferred before and after to reproduce one monitoring information.

Similarly, with respect to the other receiving units 60Ab to 60Ad, the corresponding monitoring data is inserted so as to be completed within the data block, and the corresponding data block 1 is received.
00b to 100d are configured. Each of the monitoring data has, for example, an 8-bit structure.

At the beginning of the data block 100a, start data STX (Start of Text) indicating the start of data and a command COM are added. Command COM in this case
Will insert an identification command indicating the display data for monitoring. The last data block 100d has end data ETX (End of Text) indicating the end of the data.
Is added to form packet data whose minimum transfer unit is equal to or smaller than the packet size.

By constructing the packet data so that the information to be transferred is completed by one transfer as described above, even if the information about the data cannot be reproduced because the packet data is lost, the packet data is transmitted next. Since the information about the packet data can be completely reproduced by restoring the packet data, the loss of the packet data does not become a bottleneck in reproducing the information.

In the case of transferring the packet data as shown in FIG. 7, it is preferable that all the inserted monitoring data can be displayed in real time. According to the TCP / IP protocol, the data receiving source confirms the correctness of the received data and transfers the confirmation information as a response confirmation signal ACK to the data transmitting source, thereby improving the data transfer quality accuracy. However, in the synchronous communication (also referred to as synchronous transfer; the same applies below) method that follows this transfer procedure, it takes a transfer time to send the monitoring data once, and real-time display may not be possible.

Therefore, depending on the contents of the data to be transferred, it is preferable to give priority to the real-time processing when the packet data is the data that does not hinder the information reproduction as described above. In this case, the asynchronous communication (also called asynchronous transfer; the same applies below) method should be adopted rather than the synchronous transfer method.

To do so, the sender (receiver 20)
After the communication between the terminal device 30 and the terminal device 30 that is the receiving source is connected (established), the receiver 20 that is the transmitting source uses the transfer mode determination information (asynchronous communication command) as shown in FIG. 8A as packet data. Send to. When the receiver 20 receives this transfer mode discrimination information, the terminal device 3
Transfer processing is performed from 0, ignoring the response confirmation signal ACK.

For example, when the packet data Da is first transferred as shown in FIG. 9, the terminal device 30 transfers a response confirmation signal ACK indicating a retransmission request or a next packet data transfer request. However, this response confirmation signal AC
Without waiting for K, packet data Db, Dc, ...
・ Transfer. Even if the response confirmation signal ACK is received, it is ignored, and, for example, it is also ignored when it is a retransmission request.

When the resend request is issued, the packet data becomes an error, and the contents of the packet data cannot be reproduced. That is, information is lost, but this information is not a problem as long as it is the above-mentioned monitoring data.

On the other hand, on the terminal device 30 side, the terminal device 30
The packet data that has arrived (received) at the processing timing on the side is reproduced, and is monitored (display unit) 95 as monitoring data.
Display in the corresponding display area of. The operator can monitor the state of the wireless microphone 12 and the output state from the receiver 20 from the displayed contents.

To end the asynchronous communication mode, the process shown in FIG.
As shown in B, the asynchronous communication stop command is inserted into the packet data as the transfer mode determination information and transferred to the receiver 20 side. Upon receiving this command, the receiver 20 disconnects the connection state of the communication line, for example, in order to end the asynchronous communication mode.

FIG. 10 shows a processing example on the receiver 20 side for realizing such processing. First, after the communication line is established, a command for asynchronous communication is confirmed from the transferred data (step 110), and when this command is received, a prescribed data amount is used by using the above-mentioned plurality of monitoring data. Data blocks and packet data are generated as follows, and then a transfer data stream as shown in FIG. 6 is generated (steps 111 and 112). After that, transfer processing is performed (step 113).

This packet data transfer processing is the asynchronous communication processing as described above, and this asynchronous communication processing is continued until the asynchronous communication stop command is received, and the reception of this command monitors the asynchronous packet data. The data transfer process ends (step 11).
4).

In the above-mentioned receiver 20, between the main body CPU 71 built in the main body of the receiver and the block CPU 86 built in the receiving unit 60Aa, etc., first, in the main body of the receiver itself, menu setting processing, etc. However, in addition to the processing on the main body side, the receiver unit 60
There is a case where Aa or the like is controlled to perform a channel change (reception frequency change) process or the like.

On the other hand, the above-mentioned monitoring data transfer processing from the receiving unit 60Aa or the like is conceivable. In this case, as described above, the monitoring data is temporarily saved on the receiver side,
The stored monitoring data is transferred to the terminal device 30 side via the communication cable 48.

At that time, the main body CPU 71 and the block CP
When the processing speeds of the U86 are different, the operation of the CPU having a low processing speed is normally used as a reference, but then the overall processing speed becomes slow. When the main body CPU 71 and the block CPU 86 described above are used, the processing speed is about 10 times different, and the processing time is also about 10 times slower.

If a CPU having a high processing speed is used as a reference, data may be missed or data may not be transmitted this time. However, there are cases in which data that does not pose a problem even if data is lost is handled. The above-mentioned monitoring data and the like are the same.

The above-mentioned monitoring data and the like are received by the receiving unit 60A.
Since it is not necessary to reliably transfer all the data obtained by processing such as a to the terminal device 30 side via the receiver main body side, in this case, the data obtained by processing are transferred while thinning out as a result. However, it is not unnatural for the observer.

Therefore, the main body CPU 7 having a slow processing speed
1 as the reference and the main body CPU 71 with a slow processing speed
It is advisable to switch between the case where the block CPU 86, which has a high processing speed, is ignored and the reference is used, depending on the content of the data. In other words, when the channel changing process is performed as in the former case, the synchronization process is performed while synchronizing with the main body CPU 71, and when the process of transferring monitoring data is performed as in the latter example, CPU7
It can be said that this is an asynchronous process that transfers data regardless of 1. The distinction between the synchronous and asynchronous processing may be made by monitoring the data writing state of the buffer memories 76 and 77, for example.

For example, when the synchronous and asynchronous buffer memories 76 and 77 are prepared and the data processing is performed in the synchronous mode, the processing data is the synchronous buffer memory at the processing speed (processing cycle) of the main body CPU 71. In the case of data processing in the asynchronous mode, the processing data is written in the asynchronous buffer memory 77 at the processing speed (processing cycle) of the block CPU 86.

Then, the block CPU 86 controls the asynchronous buffer memory 77, and the block CPU 86
While writing data (monitoring data, etc.) to the asynchronous buffer memory 77 at the processing speed of, the synchronous buffer memory 76 is constantly monitored. When data (channel changing data, etc.) has been written in the synchronization buffer memory 76, the data writing to the asynchronous buffer memory 77 is stopped, and the process immediately shifts to the synchronization process. That is, the data written in the synchronization buffer memory 76 is processed at the processing speed of the block CPU 86 this time.

When a series of synchronous processing for the data is completed, the data writing processing to the asynchronous buffer memory 77 is restarted again at the processing speed of the block CPU 86.
Then, at the processing speed of the main body CPU 71, the data written in the asynchronous buffer memory 77 is read and the transfer processing to the terminal device 30 is executed. According to the above-mentioned example, this data reading process is performed every 50 msec, so that the data reading is intermittent, and in this case, the latest data written most recently is read. The latest data is displayed on the monitor 30a of the terminal device 30.

FIG. 11 shows an example of processing for realizing such synchronous processing and asynchronous processing. This is rather a block CPU provided in the receiving section 60Aa or the like.
This is an example of processing on the 86 side.

First, during the data writing process to the asynchronous buffer memory 77, the write data to the synchronizing buffer memory 76 is monitored (steps 121 and 12).
2) If there is write data here, that is, if there is data to be read, the data write process to the asynchronous buffer memory 77 is interrupted, the data is read from the synchronous buffer memory 76, and the data is read according to the data content. The processing is executed (step 123). When this process ends, the process returns to step 121 again, and the data writing process to the asynchronous buffer memory 77 is restarted.

As described above, the writing processing of the monitoring data and the like can be realized without sacrificing the processing speed of the block CPU 86, the data can be read out and processed intermittently at the processing speed of the main body CPU 71, and the synchronous processing is required. In this case, the data written at the processing speed of the main body CPU 71 can be sequentially processed at the processing speed of the block CPU 86.

The types of menus that can be set by the receiver 20 and the setting values thereof will be described later. FIG. 12 shows an example of setting mode processing when setting many menus as described above. The setting mode is local. There are modes and remote modes. Therefore, when the operation of the corresponding key 58 is confirmed in the local / remote mode processing (step 131), the setting mode at that time is determined (step 132).

When the setting mode is the remote mode, the setting mode is switched to the local mode (step 133). In local mode, only key input from the receiver is accepted, and remote signals from remote operation (signals corresponding to key operations) are prohibited. As a result, the input operation is allowed only on the receiver main body side for the selection and decision of the setting menu and the like. At the same time when the setting mode is switched, the indicator 5 provided on the front panel 51A
9 is turned on (step 134) to notify that the current setting mode is the local mode. The operator can confirm the setting mode by this lighting display.

When the setting mode is the local mode in step 132, the setting mode is switched to the remote mode (step 136). In the remote mode, only the key input from the terminal device 30 side is accepted, and the key acceptance on the receiver 20 main body side is prohibited.

As a result, the input operation of the setting menu or the like is permitted only on the receiver main body side. Simultaneously with the switching of the setting mode, the indicator 59 provided on the front panel 51A is turned off, and it can be determined that the current setting mode is the remote mode (step 1).
37).

As described above, by making only one of the operations valid depending on the setting mode, confusion of the operations can be avoided,
Useless setting operations can be eliminated. Even when the local mode is set, the terminal device 30 side may want to change the setting contents and the like. In such a case, the forced remote mode may be selected.

FIG. 13 shows an example of the processing. When the receiver 20 receives a command for forced remote processing (a remote mode code and password, etc.), it confirms the stored password beforehand. When it is confirmed that it is the same as the registered person (step 14
1) Check the setting mode, and forcibly change to the remote mode when the local mode is set (step 143). This allows remote processing. At this time, the indicator 59 is turned off (step 144). Even when the forced remote mode ends, this setting mode is maintained.

The above-mentioned receiving units 60Aa-60Ad are shown in FIG.
4 is configured. Since the configuration is common, only the receiving unit 60Aa will be described. The receiving unit 60Aa has the above-described block block CPU 86, and also has a memory means (ROM) 152 in which various control programs for setting and changing reception frequencies (channels) and menu setting processing programs are stored. To
A memory means (RAM) 153 for working is provided. Further, the received signal input from the input terminal 43a passes through the diversity receiving unit 155 and the signal processing unit 156.
To the output terminal 21A side via the microphone output circuit 157.

Although FIG. 4 illustrates the signal processing unit 85 including the diversity receiving unit, in FIG. 14, the RF level, audio output level (AF level) of the received signal generated by the signal processing unit 156, The battery level BAT and the like are temporarily stored in the buffer memory 158. Further, these data are transferred to the above-mentioned buffer memory 7 via the interface 159 and the system bus 78.
9 (see FIG. 4).

Further, the receiving section 60Aa is provided with the above-described key input section 52 composed of a plurality of keys used when setting menus and the display section 53, and is turned on in the local mode. Indicator 5
9 is also connected.

FIG. 15 is a display example of the display unit 53 when the menu items are hierarchized. In this embodiment, the following display form is adopted.

In this embodiment, menus are displayed hierarchically. In addition, menus and the like are displayed using abbreviated symbols in the hierarchy as needed. In this embodiment, the fourth
It has a hierarchical display structure up to the hierarchical level.

For example, the first display layer is the first layer (root menu layer) as shown in FIG. 15A, and the next display layer selected in the root menu is the second layer (submenu layer) as shown in FIG. 15B. To do. Further, as shown in FIG. 15C, the third menu selected in the submenu is displayed in the submenu /
It is a setting change hierarchy. Then, although not shown, the fourth layer is the same setting change layer as the final layer. In the case of a four-layer structure, the setting value will be determined in the fourth layer.

When the display unit 53 has a structure in which the display lines are arranged in upper and lower two rows, as shown in FIG. 15, the upper row 53a becomes the display row of the menu items and the lower row 53b shows the menu items and setting values at that time. It becomes a display line. "<>" Indicating the position of the shift key (cursor) is displayed on the display line of the lower stage 53b.

The menu items displayed in the lower row 53b are
All the menu items that can be selected on the display screen are displayed. Therefore, the scroll function and page feed function are unnecessary.

The abbreviated symbols increase the number of displayed characters so that the displayed contents become clearer toward the lower layers. This is because there is only one type of item displayed in the upper row 53a, and the number of characters that can be displayed increases. The display is an alpha bed display. This is because using Kanji and Hiragana limits the number of characters that can be expressed.

Next, a specific example of the menu display will be described with reference to FIG. In FIG. 15A, in the root menu, the local menu in the local mode is "Local" in English.
It is displayed like "Menu". Menu items that can be set are displayed in the lower stage 53b.

Among the menu items, “MB” is the setting menu of the receiver main body, and “WRU” is the receiving unit 60.
A setting menu set by Aa or the like, “NET” indicates a setting menu for designating the terminal device 30 in the network configuration shown in FIG. 1, and “ETC” indicates other setting items. The other setting menu is a menu for searching and setting the reception frequency.

Explaining the hierarchical display when the setting menu "MB" is selected, the sub-menu is displayed at this time (see FIG. 15B). The menu title name "MB config" is displayed on the upper stage 53a. here,
“Config” is an abbreviation for “configuration”. Bottom 5
Menu items that can be selected are displayed on 3b. "AT
“T” is the setting of the RF attenuation amount (attenuator) of the received signal, and “DC” is the DC voltage level when operating power is supplied to the receiving antennas 14A and 14B. Also,
“AF” indicates the audio output level, and “MON” indicates which of the receiving units 60Aa to 60Ad to output or mix to the output terminal PHN shown in FIG.

When the "AF" menu is selected, the third hierarchy display is displayed (see FIG. 15C). Here, the number "1"
Indicates the receiving unit 60Aa (channel 1) shown in FIG.
If "1" is selected, the audio output level here can be set. 2 shows the case where the receiving unit Ab is selected.
Although not shown, the level is set in the fourth layer.

When the menu item "NET" is selected, a screen as shown in FIG. 15D is displayed. The name (host name) of the terminal device 30 is set by "Host", and "IP" is set.
To set its IP address. By specifying the host name and IP address, data communication with the specific terminal device 30 can be realized even when the receiver 20 is connected to the network.

FIG. 16 shows an example of such a menu setting process. When the power of the receiver 20 is turned on, this menu setting program is activated, and the display section 53 first displays a display indicating either the local mode or the remote mode (step 171). This display shows the previous mode. In the remote mode, if the local mode is selected using the key 58 of FIG. 3 (step 172), the display state of FIG. 15A is obtained (step 17).
3). Thereafter, the menu selection and determination processing described with reference to FIG. 15 is executed (step 174).

Next, the operation state of the menu key 54 is monitored (step 175). If the menu key is not pressed, it means that the menu operation selected first has not been completed, so the process returns to step 174 and the menu is returned. The selection and determination process of is continued.

On the other hand, when the menu key 54 is pressed, the step 17 is executed again unless the power is turned off.
Returning to step 3, the menu selection process (FIG. 15A) is performed (step 176).

The terminal device 30 described above is adapted to be able to communicate with a plurality of receivers 20 connected via a network line, and the terminal device 30 side performs various setting processes for all receivers. The change processing can be executed remotely, and the setting and change processing can be executed for the receiving units equipped in the respective receivers. In addition to these processes, a plurality of monitoring data transmitted from the receiver main body and a plurality of receiving units can be received and displayed in corresponding areas on the display screen for monitoring.

FIG. 17 shows a display example of the display screen 30a. This display screen 30a has a plurality of display areas (display section).
In this example, the uppermost stage 53a serves as the display section 179 of the menu bar, and the upper left section of the screen is the tree display section 1

A detailed setting section 184 for the receiver is located on the lower left side of the display screen 30a, and an event log display section 186 is provided next to it. The event log refers to displaying an abnormal state during operation of the receiver with characters or symbols, and for example, when a failure occurs, the operator is informed which part of which receiving section is out of order.
This event log is also recorded in a log file (described later). The monitor switch S is at the lower right of the display screen 30a.
The serial number of the monitor cell group displayed on the monitor cell display unit 182 is displayed on the operation unit of / S.

Next, details of these display units will be described.
If the file icon displayed on the menu bar 179 is designated and the process of saving is performed, the contents of various setting processes using the display screen 30a are saved as they are in the condition setting file. The condition setting file is prepared for each receiver and the receiving unit, but it can be saved by a method other than this.

On the tree display section 180, all the hardware controlled by the terminal device 30 and therefore all the receiving sections equipped in the receiver are displayed as icons. The main icons 190, 191, ... Are icons showing this receiver.

Receiving unit 6 associated with each receiver 20
The sub icons of 0A, ... Are the main icons 190, 19
It is displayed as a tree in relation to 1, ... Therefore,
In the receiver 20A, the tree-displayed sub-icons 190a to 190d are icons of the receivers 60Aa to 60Ad in the receiver 20A. Main icon 19
Next to the 0, 191, ... And the sub icons 190a ,.

As the main icon and the sub icon, an icon for normal display and an icon for abnormal display are prepared for each state, and when the receiver 20 and the receiving section 60A, ... Are operating normally, The icon for normal display is displayed, and when an abnormal state occurs, it is switched to the icon for abnormal display. This allows the operator to easily distinguish between normal operation and abnormal operation.

When the specific main icon is clicked, the setting contents of the receiver are displayed in the detailed setting section 184. FIG. 17 shows an example of the display. In this example, the model of the receiver is displayed in the substantially central part thereof, and the audio level Lv and the setting conditions of the audio output that can be monitored by the headphones PHN are displayed on the upper part thereof. Is displayed. The attenuator AT for the two receiving antennas 14A and 14B is located below it.
In addition to the attenuation level (setting level) of T being displayed, the presence / absence of power supply (ATTPW) is displayed when it is necessary to supply power to the receiving antenna. When the receiver side is switched to the remote mode, the detailed setting section 18
By clicking the desired item from 4, the contents can be set or changed by remote operation.

The monitor cell display section 182 shows a case where the display can be divided into 16 at maximum. Therefore, in this example, one horizontal row displays the contents of four receivers provided in one receiver. FIG. 18 shows a setting screen example (cell display example) in the receiving unit.

FIG. 18 shows an example of setting and management screen display in the receiving unit on the monitor cell. The receiving unit 60A
The name (channel number) given to a or the like makes it possible to distinguish from other receiving units. The group number GP of the wireless microphone 12 used in the receiving section is displayed,
The reception frequency (the transmission frequency of the wireless microphone 12) and, if necessary, the identification code ID of the group GP are displayed.

Further, the RF reception levels of the receiving antennas 14A and 14B (generally referred to as A and B) are displayed in a bar graph in the horizontal direction in the substantially central portion of the monitor cell, and the audio output level (AF level) is displayed in the vertical direction. In addition to the bar graph display and the transmission indicator of the wireless microphone 12, the battery level display, tone squelch TSQ, and noise squelch NSQ on / off indicators are displayed. By switching the setting condition of the receiver 20 to the remote mode, the use group and the reception frequency of the wireless microphone 12 can be set and changed on the monitor cell according to the table of FIG. In addition to this, the presence or absence of squelch can be set remotely.

On the event log display area 186, the name of the receiver in which the abnormal condition has occurred and the monitor cell number (the continuous number given from the left side to the right side) are displayed, and the time when the abnormal condition has occurred is displayed. After being displayed, the content indicating the abnormal state is displayed. The relationship between the abnormal state and the content indicating the abnormal state can be tabulated in advance, and the tabulated content can be used.

As an example, the wireless microphone 12
When the battery level of the
An expression such as "y Level is Low" is used. In addition to this, the default contents corresponding to a communication error between the receiver main body and the receiving unit and a case where the sound output is turned off when the tone signal cannot be received are displayed. In addition,
In such a case, the corresponding indicator is lit and displayed.

FIG. 19 shows an example of processing associated with drag and drop. When the main icon of the plurality of display icons displayed in the tree display section 180 is dragged and dropped at a predetermined position on the monitor cell display section, the All monitor screens for the four receivers related to the receiver relating to the main icons 190, 191, ... Are displayed at the drop positions (steps 201, 202). here,
The monitor screen is the screen shown in FIG.

On the other hand, when the tree-displayed sub-icons 190a, 190b, ... Are dragged to the main icon and dropped at a predetermined position or an arbitrary position on the monitor cell display portion 182, the reception of the dragged sub-icon is received. Only the monitor screen for the copy is displayed (step 203).

When the drag and drop operation of the sub icons 190a, 190b, ... Is completed (step 2
04), the setting and changing process using the monitor screen becomes effective (step 205). The setting / changing process is the setting process of the transmission frequency in the set group used in each receiving unit as described above, and the setting group and the setting frequency are displayed on the monitor screen.

When the monitor switch 188 on the display screen is operated, the monitor processing is started and the display processing of the monitor data sent from each receiving section is performed (steps 206 and 2).
07). In this example as the monitoring data, the RF of the received signal
The level, the audio output level (AF level), and the battery level of the wireless microphone 12 are displayed, and further, in this example, setting data (squelch-on, squelch-off) indicating whether to squelch the received signal as shown in FIG. 18 and noise. It is setting data indicating squelch-on or squelch-off for a signal.

Here, the RF level, the AF level, etc. are displayed in a bar graph as shown in FIG. In the case of squelch, it is lit up with squelch-on, and lit up with low battery.

Such monitor display processing is continued until the monitor start switch is turned off, and the display processing is frozen at the same time when the switch is turned off (step 20).
8). Then, by doing so, it is possible to display the monitoring data for all the receiving units, and it is possible to perform remote centralized management.

As described above, in the tree display section 180, all the hardware (receiver, receiving section, etc.) managed by the terminal device 30 is tree-displayed using icons, and
The operator can be alerted by changing the type of icon depending on whether the managed hardware is normal or abnormal.

FIG. 20 shows an example of icon display switching processing at the time of abnormality. When the monitor switch is turned on and the monitor mode (management mode) is started, a tree-structured icon is displayed on the icon display section (step 210), it is possible to confirm which receiver is operating and how many receiving units are operating in the receiver by a tree display of icons.

Next, the abnormal states of the iconified receiver and the receiving section are checked (step 211), and when an abnormal state of the receiver itself or the receiving section is detected, an icon relating to the hardware causing the abnormality is detected. Is switched from the normal display icon to the abnormal display icon and displayed (step 212). This makes it relatively easy to determine which hardware is causing the abnormality.

This abnormal display icon is continuously displayed until the normal operation is restored (steps 213, 21).
1) When it returns to normal, it is returned to the normal display icon (step 214). This normality / abnormality monitoring continues until the monitor mode ends (step 215). Note that when the icon is switched to the abnormality display icon, the target icon may be displayed in a blinking manner to draw attention to the icon.

In parallel with this abnormality processing, what kind of abnormality content is diagnosed, and if the diagnosis content can be displayed or recorded on the display screen, failure information can be promptly and accurately provided to the operator. I can inform you,
If you can leave it as a log (history), you can use it as a material for the next improvement. The embodiment also performs such processing.

FIG. 21 shows an example of such abnormality diagnosis display processing. The abnormality diagnosis processing starts at the same time as the monitor mode (steps 221 and 222), and an abnormal situation occurs in the receiver main body and each receiving section. When it occurs, a message notifying that an abnormal state has occurred is displayed on the display unit (steps 223 and 224). In addition to this display processing, the contents of the abnormal state are diagnosed and what happened in which department is saved in a log file (step 22).
5). The process of diagnosing, displaying, and saving to the log file of this abnormal state continues until the monitor mode ends (step 226). By executing such a process, when an abnormality occurs, the operator can be immediately notified, and by analyzing the data in the log file, the optimum preventive measure can be promptly taken.

The contents set and changed using the display screen as described above are saved in the condition setting file by clicking the file on the menu bar, and the contents of this condition setting file are read at the next startup. As a result, the management process can be performed with the contents set immediately before.

In the above embodiment, the centralized management system of the present invention is applied to a plurality of receivers connected in cascade. Since one receiver handles signals from a plurality of wireless microphones, a considerable amount of information must be centrally managed. According to the present invention, since this can be centrally monitored, it is possible to easily observe the monitoring of the wireless microphone and the receiver itself, including the menu setting and decision processing, on one monitor.

In the above-described embodiment, the present invention is applied to the receiving system for receiving the signal from the wireless microphone. However, the signal is received and the signal related to this received signal is sent to the terminal device or the like. The present invention can be applied to various transmission / reception system systems.

[0141]

As described above, in the signal transmitting / receiving method according to the present invention described in claims 1 and 6, and the receiver using the same, the local mode which is the setting mode on the receiver main body side is provided. And a remote mode by an external remote signal.When the local mode is selected, the setting process by the remote signal is basically prohibited, and when the remote mode is selected, the setting process in the local mode is performed. It has been banned.

According to this, when the mode is switched to the local mode and the menu is selected by the key operation on the receiver side or the setting value of the selected menu is determined, the remote mode is prohibited and the terminal device side This can be eliminated even when a remote signal is input. By doing so, menu setting processing and the like can be performed without being aware of the remote signal.

When the mode is switched to the remote mode, the operation is the reverse of that described above, and even if an attempt is made to operate the key on the receiver side, the key input is prohibited and the key operation becomes invalid. By doing so, there is a practical advantage that the confusion of the setting operation can be avoided.

In the central control system for a receiver according to the present invention described in claim 8, a receiver having a local mode and a remote mode as setting modes, a remote signal is sent to the receiver, It has a terminal device for monitoring and displaying that can receive various monitoring data from the receiver and display it, and when the remote mode is selected, the setting process can be executed by the remote signal and its contents can be displayed. It is possible to display or display monitoring data.

In this way, in addition to the feature that various menu settings can be remotely controlled even for the receiver installed at a place distant from the terminal device, the wireless microphone including the state of the received signal to the receiver can be used. The battery level and audio output level of can be monitored at the same time.

Further, when the number of wireless microphones that can be handled by the receiver is large and the receivers are connected in cascade, it is necessary to monitor a large number of states. According to the present invention, however, the terminal device can perform centralized management. Therefore, there is a real benefit such as easy monitoring and management of a wireless microphone.

Therefore, the present invention is extremely suitable when applied to a wireless microphone receiving system for receiving a signal from the wireless microphone as described above.
