Description

The present invention relates to a calling system in which a receiver and a portable display perform a calling display necessary for progress of work by a calling operation of a calling device arranged on an assembly line or the like of a factory.

Conventionally, in factories that mass-produce products, workers assigned to each process of the assembly line attach, process, inspect, etc. to the equipment that flows through the assembly line by conveyor belts, etc. The line production method is adopted to carry out the flow work.

In such a line production method, in order to improve the production efficiency of products, it is necessary to smoothly support the workers assigned to each process of the assembly line, such as supply of parts and inspection and repair. A line worker is constructing a calling system that calls the manager of the production line, the person in charge of parts supply, inspection and repair, etc. to request support.

In the conventional calling system, the receiver receives a calling signal by the calling operation of the calling device arranged on the assembly line, and the monitoring device of the receiver displays the calling contents corresponding to the calling operation. For example, when a part is likely to be insufficient on the assembly line or a trouble such as a malfunction of work equipment occurs, the worker operates the caller in response to the shortage of parts or the trouble and sends a call signal to the receiver. , The receiver outputs a ringing sound and displays on the monitor device that there was a calling operation such as a shortage of parts or trouble, arranged in the order of calling, and is monitored by the production line manager, parts supply, inspection and repair, etc. We check the call display of the device and take necessary measures promptly and appropriately.

In addition, the caller used in the conventional call system is powered by a battery and requires regular charging and replacement, which makes maintenance difficult. Therefore, in recent years, switches have been used. Battery-less callers that transmit call signals by electromagnetic induction type self-power generation that accompanies operation are also becoming widespread.

Japanese Unexamined Patent Publication No. 2017-168138 JP-A-2015-061227

However, in the conventional calling system, the contents of the call by the operation of the caller are collectively displayed on the monitor device of the receiver having a screen of a size that can be confirmed from a distance, and the manager of the production line, Persons in charge of parts supply, inspection and repair, etc. need to distinguish the call display related to themselves from the call display of the monitor device that is displayed all at once. It is necessary to check the call display, and if the number of call displays is large, it takes time and effort to check, and there is a problem that the work load is heavy. Further, depending on the manager and the person in charge, there is a case where he / she is in charge of a plurality of processes, and since he / she confirms and responds to the call display for the plurality of processes in charge of himself / herself, there is a problem that the work load becomes even larger.

In order to solve this problem, the person in charge of the support department is given a mobile display such as a smartphone, and the call display displayed on the monitor device of the receiver is transmitted to the mobile display to display it, and it becomes the call destination. It is conceivable to make it possible to check the call display at the hands of the administrator and the person in charge.

However, even if the confirmation on the monitor device is not required and the call display can be confirmed at hand on the portable display, the call display not related to the call display related to oneself is similar to the call display displayed on the monitor device. Is displayed in a mixed manner, so it is necessary to check the call display related to yourself from among them and take necessary measures, and the time and effort required to confirm when the number of call displays is large has not been eliminated. In addition, there is a concern that it may be overlooked because it is confirmed on a screen smaller than the monitor device.

In order to solve this problem, a plurality of callers and a plurality of portable displays to be called are grouped, and for example, the same group address is set for the callers and mobile displays belonging to the same group. However, the caller sends a call signal including its own group address, and the portable display receives only the call signal of the group address to which it belongs and displays the call, which is affected by the call display of other groups. You can check the call display related to yourself and respond quickly without having to.

However, if the calling device is a battery-less calling device that transmits a calling signal by instantaneous electromagnetic induction type self-power generation by operating a switch, the generated power is weak, so the calling signal is only for a short time, for example, 1 ms. The amount of data of the calling signal to be transmitted is limited, and the transmitted data is, for example, the transmitter address, the calling device model number, the button number, the radio field strength, the check sum, and the demilita (separator code). If you set the group address to which you belong in addition to this, the data length may become long, and the generated power may be insufficient during transmission, making it impossible to transmit a normal ringing signal.

In addition, the group address set in the calling machine needs to be changed as necessary due to a change in the assembly line or a change in charge. However, since the battery-less caller can only obtain the instantaneous power generated by the switch operation, the group address set at the manufacturing stage cannot be changed immediately during operation, and it is manufactured to change. It is necessary to prepare the same equipment as when setting in stages. Therefore, with the change of grouping, it is necessary to prepare and replace a new caller with the changed group address, or to prepare equipment for resetting the group address, which increases the operating cost. It will be bulky.

Further, as another method for grouping the caller and the portable display device, it is conceivable to assign different channel frequencies to each group. However, if the caller is provided with a function for switching and selecting the channel frequency in advance so as to be able to cope with a group change that is not always performed, the configuration of the caller becomes complicated and the cost increases.

INDUSTRIAL APPLICABILITY The present invention enables grouping without incurring a cost to the caller when the call signal is transmitted from the caller and the receiver and the portable receiver display the call, which is required for the portable display. It is an object of the present invention to provide a calling system that can display only the calling display of a group and can easily respond to a change in grouping without incurring an operating cost.

The first wireless network sends a ringing signal from a plurality of callers to the receiver using one channel frequency in a given specific low power communication.
The second wireless network uses a predetermined wireless local area network (wireless LAN) to send and receive signals between the receiver and the plurality of portable displays.

(Effect of calling system 1)
According to the calling system 1 of the present invention, a plurality of portable display devices belonging to a group to be called are grouped by different departments that supply parts, maintain and inspect, for example, to workers on an assembly line. The receiver registers the correspondence between the caller that is the caller and the group that is the callee, and the receiver generates call frame information for displaying the predetermined call content based on the reception of the call signal from the caller. By displaying the call frame, which is the predetermined call content, and transmitting the call relay signal including the call frame information that specifies the group of the call destination to multiple portable displays, the receiver supports all call signals. However, on the mobile display, only the call frames corresponding to the call relay signal that specifies the group to which you belong are displayed, and the call frames of other groups to which you do not belong are displayed. Instead, the person in charge of possessing the portable display can easily and easily confirm the call to the group to which he / she belongs and take prompt and appropriate measures.

(Effect of calling system 2)
Further, in the calling system 2 of the present invention, in addition to the same basic effect as the calling system 1 described above, since the calling device is provided with a plurality of calling buttons, each calling button of the calling device is used by the receiver. By setting the correspondence between the call button of the caller and the group to be called as table information, even if the same caller is used, the mobile display belonging to different groups can be displayed by multiple call buttons. The machine can be called. For example, a worker on the assembly line can operate different call buttons provided on the same caller in case of a situation with a different call destination such as a shortage of parts or a malfunction of work equipment. Therefore, the call can be made only to the portable display belonging to the specific group associated with the call button, and the person in charge belonging to the group receiving the call can be called without being hindered by the call to another group. , You can check with a portable display that only brings a call to the group to which you belong, and respond quickly and appropriately to the call from the work side.

(Effect of the contents of the call frame)
Further, the call frame displayed by the receiver and the portable display is a predetermined caller name (for example, an assembly line name) indicating the caller, and a predetermined group indicating the group to which the portable display to be called belongs. Group name (for example, XX group, XX department), elapsed time from the time when the call signal was received (for example, the time such as "0 minutes before" indicating how long before the current time the call signal was received) Since it is included, the person in charge of the call destination can accurately determine the call location, the content of the call, and the call status such as when the call was made from the call frame displayed on the monitor unit of the receiver or the portable display carried. It is possible to catch the call and respond to the call.

(Effect of belonging to multiple groups of mobile display devices)
In addition, the mobile display device grouped so as to belong to a plurality of predetermined groups displays a call frame based on a plurality of call frame information specifying the group to which the mobile display belongs received from the receiver, for example. For the manager or the person in charge of multiple groups, the manager or the person in charge of multiple groups can easily check the overall status of the assembly line by displaying the call to the multiple groups in charge on one mobile display. be able to.

(Effect of priority display of call frame)
Further, by setting a priority display instruction corresponding to a caller or a call button of high importance such as an emergency call in the table information of the receiver, for example, a plurality of call frames are already displayed in the order of the call on the monitor unit. When a call signal is received from the caller for which the priority display instruction is set or the call button of the caller, the call frame corresponding to the priority display instruction takes precedence over the start position of the call frame already displayed. It is displayed in conjunction with the display of the monitor unit even on the portable display, and the person in charge who owns the portable display knows the important call such as an emergency call and takes prompt action. Make it possible.

(Effect of call cancellation)
In addition, among the table information of the receiver, some of the call buttons of the caller or the caller are not set to have a correspondence with the group, and the call cancellation instruction is set, so that the caller or the caller has no correspondence. A part of the provided multiple call buttons can be made to function as a call cancel button. For example, when the person in charge responds to the call, the operator can operate the call cancel button to already receive and carry the receiver. The call frame displayed during a call on the display side can be easily deleted.

(Effect of canceling the call on the terminal display)
In addition, the call display on the portable display can cancel the call frame information by a predetermined call cancellation operation and delete the call frame. For example, the person in charge of receiving the call goes to the caller to respond. When you are done, you can easily delete the corresponding call frame by canceling the call on your portable display. In addition, the call frame information on the receiver is canceled and the call frame on the monitor unit is deleted in conjunction with the call cancellation operation on the mobile display, and at the same time, the history frame information corresponding to the canceled call frame information is automatically displayed. Can be generated and stored in.

(Effect of the contents of history frame information)
Further, the history frame information includes a predetermined caller name (for example, an assembly line name) indicating a caller corresponding to the canceled call frame information, and a group to which the portable display to be called belongs. In addition to the specified group name (for example, XX group, XX department), the additional information associated with the cancellation includes the response completion time for the call and the name of the person in charge who responded, and who responded to the call display and how. Can be easily and easily grasped.

(Effects of ringing button and history button on mobile display)
In addition, the portable display is equipped with a ringing button and a history button by displaying a screen, etc. Normally, by operating the ringing button, the ringing frame before erasing is displayed after receiving the ringing relay signal. On the other hand, by operating the history button as needed, the history frame information corresponding to the deleted corresponding call frame information is displayed as a history frame, and the past calls that have been handled and their correspondence status are displayed. You can easily check it.

(Effect of call button invalidation instruction)
In addition, in the table information of the receiver, a part of the caller or the call button of the caller has no correspondence with the group, and the invalid instruction of the caller or the call button of the caller is set. Therefore, even if an unused caller or call button is erroneously operated, the operation is invalidated and confusion due to the erroneous operation can be prevented.

(Effect of additional registration of table information)
Further, in the table information of the receiver, the display color and the ringing sound of the calling frame corresponding to the calling button of the calling device or the calling device are set, and the calling device or the calling device in which the display color and the ringing sound are set are set. When a call signal is received from the call button of, the call frame is displayed by the display color acquired from the table information and the ring sound acquired from the table information is output to display the call frame displayed on the receiver and the portable display. , It is possible to easily distinguish and distinguish.

(Effect of wireless network)
Further, the plurality of callers and the receiver are connected via the first wireless network, the receiver and the plurality of portable displays are connected via the second wireless network, and the first wireless network is a predetermined specification. The call signal is transmitted from multiple callers to the receiver using one channel frequency in low power communication, and the second wireless network uses a predetermined wireless local area network (wireless LAN) to send the call signal to the receiver. By transmitting and receiving signals between and multiple portable displays, for example, the first wireless network uses one channel of specific low power communication in the 920 MHz band, so that the channel frequencies of all callers are the same. , It is possible to reduce the cost by simplifying the configuration of the caller that operates by the instantaneous electromagnetic induction power generation accompanying the operation of the call button and transmits the call signal. In addition, the second wireless network uses a known wireless LAN such as WiFi (registered trademark) provided in a smartphone used as a mobile display, or a known short-range wireless communication such as Bluetooth (registered trademark). This enables a simple and reliable communication connection between the receiver and the portable display via a wireless line.

Hereinafter, embodiments of the calling system according to the present invention will be described in detail with reference to the drawings. The present invention is not limited to the following embodiments.

[Basic concept of embodiment]
Embodiments are generally related to a calling system. In the calling system, when a worker on an assembly line of a factory calls a calling device, the calling is displayed on a receiver and a portable display, and the person in charge of the calling destination proceeds with the work. It is a system to take necessary measures such as. Here, the "call display" means to display information indicating a predetermined call content on a receiver or a portable display, and the type and form of the call display are arbitrary, but in the present embodiment. Means that the "call frame" is displayed on the receiver or the portable display based on the "call frame information" indicating the predetermined call content.

The calling system of the present embodiment is composed of a plurality of calling devices, a receiver including a monitor unit, and a plurality of portable display devices.

The "calling machine" is, for example, placed in the vicinity of a worker placed in each process of the assembly line, operates by instantaneous electromagnetic induction power generation accompanying the operation of the calling button, and sends a calling signal to the receiver. It is to be transmitted, and the number of call buttons may be plural, and the number is arbitrary. Here, "electromagnetic induction power generation" means that, for example, the induction coil and the permanent magnet are relatively moved by mechanical movement accompanying the operation of the call button, and electric energy is generated by the change of the magnetic flux passing through the induction coil. Since it is self-generated, it realizes a so-called battery-less caller that does not require a battery power source.

Further, the "call signal" is a signal indicating that the call button of the caller has been operated, and although the signal format of the call signal is arbitrary, information that enables the caller or the call button of the caller to be identified. Is included. The information that makes the caller identifiable includes, for example, the address set for each caller, and the information that makes the caller of the caller identifiable includes, for example, the call button number indicating the operated call button. be. Here, the "call button number" is a number for identifying the operated call button, but is not limited to the number, and is a concept including an identifier, an identification code, an identification code, an address, and the like. .. The call signal is a signal that includes information for specifying the caller by including the call button number, but does not include information for specifying the callee, and the callee is specified by the receiver described later. be.

The "receiver" is a correspondence relationship between a caller as a caller and a group as a callee, or a call as a caller, on the assumption that a plurality of portable displays are grouped into a plurality of groups. It has table information that sets the correspondence between the call button of the machine and the group that is the call destination, and by referring to the table information based on the call signal received by the caller, the predetermined call content, for example, the caller name and the call. Generates call frame information for displaying the destination group name, etc., displays the call frame on the monitor, generates a call relay signal including call frame information that specifies the destination group, and sends it to multiple mobile displays. It is to be sent.

Here, the "call frame information specifying a group of call destinations" is call frame information including a "call destination group" which is information for identifying a group of call destinations, and is referred to as a "call destination group". Is a concept including a group address, a group name, an identifier, an identification code, an identification code, and the like.

Further, the "table information" is information registered for each caller, for example, table information in which a caller name, a call button number, and a correspondence relationship with a callee group are registered, and is a concept including a lookup table. It is not limited to the table format, and includes an appropriate information format for registering the correspondence. Further, the "call frame information" is information for displaying the contents of the call of what kind of call was made from the caller, and is a group indicating the caller name and the call destination of, for example, the assembly line in which the caller is installed. This is information including call frame image data in which a name, an elapsed time from a call, and the like are collectively displayed on a monitor unit, for example, in one call frame (display frame). Further, in the table information, for example, a display color and a type of ring tone are registered in advance corresponding to the call button number, and the call frame is displayed on the monitor device in the display color based on the table information. The ring tone is output from the monitor unit based on the table information.

Further, in the table information of the receiver, a priority display instruction is registered in advance corresponding to the caller or the call button of the caller, for example, the call button number of the caller, and the call button included in the call signal received from the caller. When the priority display instruction corresponding to the number is acquired from the table information, the call frame corresponding to the priority display instruction is displayed at the predetermined head position of the monitor unit, and in conjunction with this, the terminal display also corresponds to the priority display instruction. The call frame is displayed at a predetermined start position.

Further, the "monitor unit" displays the call content (call frame) of what kind of call was made from the caller, for example, a monitor device connected to the receiver, a monitor provided in the receiver itself, or the like. It is a concept including.

A "portable display" is, for example, a portable display carried by a person in charge of a department that provides maintenance and inspection support for the supply of insufficient parts to the assembly line where the caller is placed and the occurrence of a defect. It is a mobile device with a display such as a smartphone, and it is divided into groups by selecting and registering the group to which the person in charge belongs in advance, and when the call relay signal is received from the receiver, it belongs to oneself. The call frame is displayed on the display based on the call frame information included in the call relay signal for which the group of the call destination is specified. The mobile display enables one or more group selection registration of the group to which the mobile display belongs. In addition to selecting and registering one or a plurality of groups, the mobile display device is also provided with, for example, a function of selecting and registering all groups at once.

On the other hand, the receiver can make a part of the caller or a plurality of call buttons provided on the caller function as a call cancel button for canceling the call. Therefore, in the table information of the receiver, a call cancel instruction is registered in advance corresponding to the caller used as the call cancel button or the call button of the caller, for example, the call button number, and the received call signal is called. When a call cancellation instruction is obtained by referring to the table information by the button number, the call frame information of the corresponding monitor unit is canceled and the call frame is deleted, and the call relay signal excluding the call frame information corresponding to the deleted call frame is carried. By transmitting to the display device, the call frame to be canceled is deleted by the update display on the terminal display device. The call cancel instruction includes the concept of a call cancel command or a call cancel command.

Here, the receiver displays the call frame on the monitor unit and displays the same call frame on one or more portable displays connected to the receiver, and the monitor unit adds, changes, or deletes the call frame. Is performed, the call frame is added, changed, and deleted on the portable display in conjunction with this. In this way, the display control in which the monitor unit and the display of the call frame on one or more mobile display devices are linked by the receiver is, for example, mirroring of the so-called one-to-n screen display, synchronization of the screen display, or screen display. It includes the concept of sharing.

In addition, when the person in charge responds to the call, the call cancellation operation is performed on the portable display, and when the call frame information is canceled on the portable display by a predetermined call cancellation operation and the call frame is deleted, the call frame is deleted. A call cancellation notification signal is transmitted to a receiver to cancel the corresponding call frame information to erase the call frame, and at the same time, history frame information is generated and stored. Further, the history frame information stored when the call frame information is canceled by operating the mobile display can be viewed on the mobile display as needed.

Further, when there is an unused caller or call button among the plurality of call buttons provided in the caller or caller, the receiver can make the unused caller or call button invalid. Therefore, in the table information of the receiver, a call button invalidation instruction is registered in advance corresponding to the call button of the unused caller or the caller, for example, the call button number of the call button, and the received call signal is called. When the call invalid button instruction is acquired by referring to the table information by the button number, the process is invalidated and nothing is done. The call button invalid instruction includes the concept of a call button invalid command or a call button invalid command.

Further, the plurality of callers and the receiver are connected via the first wireless network, and the receiver and the plurality of portable displays are connected via the second wireless network. Here, the "first wireless network" is a network that transmits a call signal from a plurality of callers to a receiver using one channel frequency of a predetermined specific low power communication, and is, for example, in the 920 MHz band. It uses one channel frequency of the specified low power communication. The "second wireless network" is a network that sends and receives signals between a receiver and a plurality of terminal displays using a predetermined wireless local area network (wireless LAN) or short-range wireless network. Yes, for example, it is a concept including a wireless network such as WiFi (registered trademark) and Bluetooth (registered trademark) provided in a smartphone used as a portable display.

Hereinafter, specific embodiments will be described. In the embodiment shown below, a plurality of callers are arranged on the assembly line of the factory, a plurality of terminal displays are grouped into groups G1 and G2, and the callers are provided with four call buttons.

[A. Calling system overview]
FIG. 1 is an explanatory diagram showing an outline of a calling system, and is taken as an example when applied to an assembly line of a factory. The calling system of the present embodiment includes a plurality of calling devices 10, a first wireless network 14, a receiver 16, a monitoring device 18, a second wireless network 20, a plurality of portable display devices 22, a setting device 24, and a history collecting device. It is composed of 26. The setting device 24 and the history collecting device 26 are configured to be provided as needed.

The calling machine 10 is arranged in the vicinity of the operator arranged in each process of the assembly line. For example, the assembly line is composed of a first assembly line L1 and a second assembly line L2. The first assembly line L1 is divided into, for example, the first process L1-1 and the second process L1-2, and each process is accompanied by workers 15a and 15b, which are called in response to the workers 15a and 15b. The machine 10 is arranged. Further, the second assembly line L2 is also divided into, for example, the first process L2-1 and the second process L2-2, and each process has workers 15c and 15d corresponding to the workers 15c and 15d. The calling machine 10 is arranged.

The calling machine 10 includes, for example, four calling buttons 12a, 12b, 12c, 12d. The number of call buttons is arbitrary. When any one of the call buttons 12a to 12d is pushed in, the built-in call button switch turns on and operates by receiving the electric power generated by the instantaneous electromagnetic induction power generation accompanying the pushing operation, and the call signal E1 is transmitted to the first wireless network 14. It is transmitted to the receiver 16 via. The call signal E1 includes at least a caller address unique to the caller 10 and a call button number indicating the operated call button.

The receiver 16 receives the call signal E1 transmitted from the caller 10 to generate call frame information indicating a predetermined call content, and displays the call frame on the monitor screen of the monitor device 18 based on the call frame information. At the same time, a ringing sound is output from the speaker of the monitoring device 18 to indicate that the call has been made. Further, the receiver 16 transmits a call relay signal E2 designating a group of call destinations to the connected mobile display 22 via the second wireless network 20 based on the reception of the call signal E1. The timing of transmission of the call relay signal E2 from the receiver 16 is arbitrary, and is performed, for example, every predetermined cycle or every time an event such as addition, change, or deletion of a call frame occurs.

Here, the portable display 22 is divided into a group G1 for supplying parts and a group G2 for performing maintenance and inspection in response to calls from workers 15a to 15b of the first and second assembly lines L1 and L2. There is. Three persons in charge of 25a, 25b and 25c belong to group G1, and two persons in charge of 25c and 25d belong to group G2, each of which has a portable display 22. The person in charge 25c is a person in charge who belongs to both groups G1 and G2.

The receiver 16 corresponds to the grouping of the mobile display 22 and has a caller name indicating the installation location of the caller 10 and a group G1 of the call destination to which the mobile display 22 belongs for each address of the caller 10. , The correspondence with G2, etc. are registered in advance as table information to be clarified in a later explanation. For example, the group G1 is registered corresponding to the call button number of the call button 12a in the caller 10, and the group G2 is registered corresponding to the call button number of the call button 12b. Therefore, the call button 12a of the caller 10 functions as a call button of the group G1, and the call button 12b functions as a call button of the group G2.

When the receiver 16 receives the call signal E1 from the caller 10, it generates call frame information including the caller name and the call destination group obtained by referring to the table information, and displays the call frame on the monitor device 18. , The call relay signal E2 including the call frame information specifying the group G1 or G2 of the call destination is transmitted to all the connected terminal callers 22.

The mobile display 22 is, for example, a smartphone, and the groups G1 and / or G2 to which the portable display 22 belongs are preset before operation. For example, group G1 is set for the mobile display 22 of the person in charge 25a and 25b, groups G1 and G2 are set for the mobile display 22 of the person in charge 25c, and group G2 is set for the mobile display 22 of the person in charge 25d. Is set. Therefore, the portable display 22 displays the call frame on the display based on the call frame information that specifies the call destination group G1 or G2 that matches the group G1 or G2 to which the portable display 22 belongs, which is included in the received call relay signal E2. do. As a result, the monitor device 18 connected to the receiver 16 displays a call frame for all of the groups G1 and G2, but the portable display 22 displays a call frame for which the group G1 and / or G2 to which the user belongs is designated. Will be displayed.

Further, in the table information of the receiver 16, registration can be performed in which the call destination group is designated as all groups corresponding to the call button number of the call button 12c in the caller 10. As a result, the receiver 16 can make the call button 12c of the caller 10 function as an all-group call button.

Further, in the table information of the receiver 16, a "priority display instruction" is registered corresponding to a specific call button in the caller 10, for example, a call button number of a call button having a high degree of urgency. As a result, when the receiver 16 receives a call signal including the call button number in which the priority display instruction is registered while displaying a plurality of call frames on the monitor device 18 in the call order, the receiver 16 displays the call frame on the monitor device 18. It can be displayed at the beginning of the call frame that has already been displayed in. Along with this, also in the portable display device 22, the call frame of the call button number in which the priority display instruction is registered is displayed at the head position in conjunction with the display of the monitor device 18.

Further, in the table information of the receiver 16, "call cancellation instruction" is registered corresponding to the call button number of the call button 12d in the caller 10. As a result, the receiver 16 can make the call button 12d of the caller 10 function as a call cancel button. For example, after the operator performs the call operation, the call can be canceled by operating the call button 12d of the caller 10 when the person in charge of the call destination does not need to take action or when an erroneous operation is performed.

On the other hand, also in the portable display device 22, the call can be canceled and the display of the call frame can be erased by a predetermined call cancellation operation. Cancellation of the call by the mobile display 22 is an operation performed when the person in charge who received the call goes to the caller to perform parts replenishment, inspection and repair, etc., and the mobile display is accompanied by this call cancellation operation. 22 transmits the call cancellation notification signal E3 to the receiver 16 via the second wireless network 20. The call cancellation notification signal E3 includes the corresponding time information and the corresponding person in charge. When the receiver 16 receives the call cancellation notification signal E3 from the portable display 22, the receiver 16 erases the corresponding call frame displayed on the monitor device 18, and also generates the history frame information corresponding to the erased call frame. And remember. This history frame information includes the name of the caller, the group name of the callee, and the name of the person in charge corresponding to the corresponding time.

Further, when the calling device 10 has a calling button that is not used, a "call button invalidation instruction" is registered in the table information of the receiver 16 corresponding to the calling button number of the unused calling button. As a result, the receiver 16 can function as an invalid call button in which no processing is performed on the receiver 16 side even if the call button not used by the caller 10 is erroneously operated.

The setting device 24 is connected to the receiver 16 with a signal cable or the like, and performs an operation for registering the table information provided in the receiver 16. Therefore, the receiver 16 includes a server unit that downloads the registration screen to the setting device 24, and the setting device 24 downloads the registration screen from the receiver 16 by the browser unit and performs a necessary registration operation. The registration operation using the registration screen by the setting device 24 includes registration of the caller name, the callee group name, the callee group corresponding to the call button number, all groups, or the call cancellation instruction for each caller 10. It's a waste.

The history collecting device 26 is connected to the receiver 16 with a signal cable or the like, and periodically reads out, collects, and stores the history frame information stored in the receiver 16. The history collecting device 26 is not always connected, but may be connected when necessary.

[B. Grouping and call display]
Next, an example of a call display corresponding to grouping will be briefly described with reference to FIG. In FIG. 2, when the worker 15a attached to the first step L1-1 of the first assembly line L1 operates the call button 12a of his / her own caller 10 due to a shortage of parts to call the group G1, the call signal E1 -1 is transmitted to the receiver 16.

Based on the reception of the call signal E1-1, the receiver 16 refers to the table information 48 and acquires the caller name corresponding to the caller address, the call destination group G1 corresponding to the call button number, and the like, and the call frame. Information is generated, and the call frame 28-1 is displayed on the monitoring device 18 based on the call frame information. The call frame 28-1 shows the callee group G1 and the caller's first assembly line first step L1-1. The call frame 28-1 also displays the elapsed time since the call signal E1-1 was received, but it is omitted. Further, the receiver 16 generates a call relay signal including the call frame information of the call frame 28-1 designated as the call destination group G1, and is a portable display of all the persons in charge 25a to 25d connected to the receiver 16. Send to 22.

The call relay signal specifying the group G1 transmitted from the receiver 16 is received by the portable display 22 of all the persons in charge 25a to 25d, and the portable display 22 of the persons in charge 25a, 25b, 25c of the group G1 owns. The call frame 28-1 of the call frame information that specifies the group G1 to which the user belongs is displayed, but the mobile display 22 of the person in charge 25d of the group G2 displays the call frame information of the call frame information that specifies the group G1 to which he / she does not belong. 28-1 is not displayed.

Subsequently, when the worker 15c attached to the first step L2-1 of the second assembly line L2 operates the call button 12b of his / her own caller 10 due to a failure of the equipment or the like to call the group G2, a call signal is given. E1-2 is transmitted to the receiver 16. The receiver 16 refers to the table information based on the reception of the call signal E1-2, acquires the caller name corresponding to the caller address, the call destination group G2 corresponding to the call button number, and the like, and generates the call frame information. Then, the call frame 28-2 is displayed on the monitor device 18 based on the call frame information. The call frame 28-2 displays the call destination group G2 and the caller's second assembly line first step L2-1. Further, the receiver 16 receives a call relay signal including the call frame information of the call frame 28-2 that specifies the call group G2 and the call frame information of the call frame 28-1 that specifies the call group G1 that is already being called. It is generated and transmitted to the portable display 22 of all the persons in charge 25a to 25d connected to the receiver 16.

The portable display 22 of the person in charge 25a, 25b, 25c of the group G1 updates and displays the call frame 28-1 of the call frame information specifying the group G1 included in the received call relay signal on the display, but displays the group G2. The call frame 28-2 of the specified call frame information is not displayed.

Further, the portable display 22 of the persons in charge 25c and 25c belonging to the group G2 displays the call frame 28-2 of the call frame information specifying the group G2 to which the person belongs to the group G2 included in the call relay signal received from the receiver 16. It is newly displayed in. As a result, the terminal display 22 of the person in charge 25c belonging to both the groups G1 and G2 has the call frame 28-1 of the call frame information designated by the group G1 and the call frame 28 of the call frame information designated by the group G2. Two of -2 are displayed side by side in the order of reception.

[C. Calling system configuration]
Next, the configurations of the caller, the receiver, and the portable display constituting the calling system will be described in more detail with reference to FIG.

[D. Caller]
The caller 10 transmits a call signal by operating the call button, and its function, configuration, and structure are arbitrary, but as an example, the call corresponding to the plurality of call buttons 12a to 12d shown in FIG. 1 is used. It is composed of button switches 30a to 30d, a call button control unit 32, a transmission unit 34 to which an antenna 35 is connected, and an electromagnetic induction power generation unit 33.

The call button switches 30a to 30d close the contacts by pushing the call buttons 12a to 12d and output an on signal. For example, they have a seesaw structure, and when one end of the seesaw is pushed, the contacts at the other end are closed. When it is turned on and the push is released, it returns by the force of the spring and turns off.

When the on-signal by any operation of the call button switches 30a to 30d is input, the call button control unit 32 generates a call signal E1 of a predetermined format and outputs it to the transmission unit 34. The signal format of the calling signal E1 is arbitrary, but as shown in FIG. 4A, for example, it is composed of a calling device address, a calling button number, a radio wave strength, a checksum CK, a delimiter code, and the like.

The transmission unit 34 wirelessly transmits the call signal from the antenna 35, and the communication method thereof is arbitrary, but for example, any one of the 920 MHz band assigned channels known as the specified low power communication is used. And send a ringing signal. It does not prevent the use of specific low power communication other than the 920 MHz band.

The electromagnetic induction power generation unit 33 supplies the power generated by the instantaneous electromagnetic induction power generation accompanying the on operation of any of the call button switches 30a to 30d by the call buttons 12a to 12d to the call button control unit 32 and the transmission unit 34. It operates and sends a ringing signal. For example, when any of the call button switches 30a to 30d is turned on, the permanent magnet is moved relative to the induction coil to change the magnetic flux passing through the induction coil to generate electricity. The power generation of the electromagnetic induction power generation unit 33 is instantaneous power generation in which the operating power is obtained for about 1 ms. Therefore, the signal length of the call signal that can be transmitted is restricted by the instantaneous operation of the call button control unit 32 and the transmission unit 34 for about 1 ms. For example, if the baud rate is 57.6 kbps, it is restricted to about 20 bytes.

[E. Receiving machine]
The receiver 16 receives the call signal from the caller 10 and generates call frame information of a predetermined call content, displays the call frame on the monitor device 18 connected based on the call frame information, and displays the call frame from the speaker. A ringing sound is output, and a call relay signal including call frame information for which a call destination group is specified is transmitted to the portable display 22. The function and configuration thereof are arbitrary, and are shown in FIG. 3, for example. As described above, the receiver control unit 36, the reception unit 40 to which the antenna 38 is connected, and the transmission / reception unit 42 to which the antenna 44 is connected are provided. For example, the connection with the monitor device is an HDMI (registered trademark) cable, and the connection with the HDMI (registered trademark) cable is based on the high-precision multimedia interface (High Definition Multimedia Interface) standard, and the image data (image). Content) and audio data can be transferred.

The receiving unit 40 receives a calling signal transmitted from the calling device 10 via the first wireless network 14, and is one channel in the 920 MHz band of the same specific low power communication as the transmitting unit 34 of the calling device 10. It has a reception function corresponding to the frequency.

The transmission / reception unit 42 transmits / receives various signals via the second wireless network 20, and functions as, for example, a wireless router or an access point, such as WiFi (registered trademark) which is a wireless LAN, or a short distance. It is composed of a communication unit of Bluetooth (registered trademark) which is a wireless network.

The receiver control unit 36 is a computer circuit provided with a CPU, a memory, and various input / output ports, and has a call control unit 46, a table information 48, a server unit 50, and history processing as functions realized by executing a program by the CPU. A unit 52 is provided.

(E1. Call control unit)
The call control unit 46 acquires the caller name corresponding to the caller address, the call destination group and group name corresponding to the call button number, and the like by referring to the table information 48 based on the reception of the call signal E1, and the call frame information. Is generated, and display control is performed to display a call frame on the monitoring device 18. Further, the call control unit 46 controls to generate a call relay signal E2 including call frame information for which a call destination group is designated and transmit it to the portable display 22 to display the call frame. Further, when the call control unit 46 acquires the "call cancellation instruction" by referring to the table information 48 by the call button number, the call frame displayed on the monitor device 18 is deleted, and the call frame information of the deleted call frame is used. Control is performed to generate the removed call relay signal E2 and transmit it to the portable display 22 to erase the call frame. Further, the call control unit 46 controls to cancel the call frame information and erase the call frame of the monitor device 18 based on the call cancellation notification signal E3 received from the terminal display 22.

Here, the call relay signal E2 is arbitrary, but corresponds to, for example, a receiver address (receiver URL), a connected display address, or one or a plurality of display frames, as shown in FIG. 4 (B). It is a signal of a predetermined format including call frame information and the like. Further, the call frame information includes a caller address, a call destination group, a call frame image data, and the like, and the call destination group includes any one of the G1 group, the G2 group, or all the groups registered in the table information 48. It's a waste.

Further, the call relay signal E2 is repeatedly transmitted, for example, is transmitted at predetermined intervals, and is transmitted when a display event such as addition, change, or deletion of a call frame occurs, whereby the receiver is transmitted. The call frame is updated and displayed on the display of the portable display 22 in conjunction with the display of the call frame on the monitor device 18 connected to 16, but the portable display 22 uses the group to which it belongs as the call destination. Only the call frame is updated and displayed.

(E2. Table information)
The table information 48 registers the caller name corresponding to the address of the caller 10, the call button number corresponding to the plurality of call buttons 12a to 12d, the correspondence relationship between the call destination group, and the like, and the data structure thereof is Although it is optional, for example, the list format shown in FIG. 5 is used.

The table information 48 includes a caller address, a caller name, a call button number, a call target, a display priority, a display color, a ring tone, and the like. The caller address is a unique address for identifying the plurality of callers 10 shown in FIG. The caller name is information indicating the location where the caller 10 is installed. For example, the caller addresses of the caller 10 installed corresponding to the workers 15a and 15b shown in FIG. 1 are designated as A1 and A2. Then, the caller name of the caller address A1 is "1st assembly line 1st step L1-1", and the caller name of the caller address A2 is "1st assembly line 2nd step L1-2".

The call button number sets the call button numbers CB1 to CB4 unique to, for example, the call buttons 12a to 12d provided in the caller 10. Note that CB1 to CB4 are merely notations, and a predetermined bit code is actually set.

The call target is information based on specifying a call destination group corresponding to the call button numbers CB1 to CB4, and corresponds to, for example, grouping of groups G1 and G2 of the portable display 22 shown in FIG. , The group G1 is registered as the call destination of the call button number CB1, and the group G2 is registered as the call destination of the call button number CB2. The groups G1 and G2 mean group addresses unique to each group.

Further, in addition to the call destination group, "all groups" corresponding to the call button number CB3 are registered as call destinations in the call target. Further, the "call cancellation instruction" is registered corresponding to the call button number CB4. In addition to this, it is also possible to register a "call button invalidation instruction" corresponding to the call button number of the call button that is not used.

The display priority indicates the order in which a plurality of display frames to be displayed on the monitor device 18 are displayed, and "normal" or "priority" is registered. "Normal" is a normal display instruction, and displays a plurality of display frames in the order of calling. "Priority" is a priority display instruction, and the newly received display frame is displayed at the head of the display frame already displayed in the calling order.

As the display color, the display color of the calling frame to be displayed on the monitor device 18 or the portable display 22 is registered corresponding to, for example, a calling destination group, and the display color is arbitrary, but for example, the calling destination. The call frame of group G1 is "green", the call frame of callee group G2 is "blue", the call frame of all groups is "red", and the call frame targeted by the "call cancellation instruction" is also "red". ". This makes it possible to easily distinguish that the call frames belong to the same group by the same display color.

The ringing tone registers the type of the notification tone when the ringing signal is received, and the display tone is arbitrary. For example, the calling destination group G1 is "ping pong" and the calling destination group G2 is "sharan". All groups are "win-win", and "call cancellation instruction" is also "ping-pong". This makes it possible to easily distinguish that the calls belong to the same group by the same ring tone.

(E3. Call display by call frame)
The call frame 28 to be displayed on the monitor device 18 when the receiver 16 receives the call signal has an arbitrary shape and structure, but has, for example, a horizontally long rectangular shape as shown in FIG. 6A. , The group name 68 to be the call destination is arranged in the upper row, the caller name 70 is arranged in the middle row, and the elapsed time from receiving the call signal is arranged as the time information 72 in the lower row. Further, a frame frame 74 having a predetermined width is formed around the call frame 28, and when the same call signal is received twice or more, the frame frame 74 is flickered (blinks or blinks) to call attention. ing.

Specifically, as shown in FIG. 6B, the group name 68 is “parts supply group 001”, the caller name 70 is “first assembly line first step L1-1”, and time information. 72 is, for example, "5 minutes ago".

The display of the call frame 28 to the monitor device 18 is arranged as shown in FIGS. 7 and 8, for example, depending on the number of calls. The number of call frames to be displayed is divided into 1, 2, 4, 7, and 12, but the two call frames are not shown. FIG. 7A shows a case where the number of calls is one, and one call frame 28 is displayed in a large size in the center of the monitor screen 18a. FIG. 7B shows a case where the number of calls is four, four call frames 28 are displayed in 2 rows and 2 columns on the monitor screen 18a, the upper left is the latest call, and the lower right is the oldest call. FIG. 7C shows a case where the number of calls is 7, in which 3 call frames 28 are displayed in the order of newest from the left in the upper row, and 4 call slots 28 are displayed in a slightly smaller size in the lower row. .. Further, FIG. 8 shows a case where the number of calls is 12 which is the display limit, 12 call frames 28 are displayed in 3 rows and 4 columns, and the 13th and subsequent calls exceeding 12 are scrolled on the screen. ..

(E4. Server section)
The server unit 50 includes a registration screen necessary for the registration operation of the table information 48 shown in FIG. 5, and downloads and requires the registration screen by the browser unit provided in the setting device 24 shown in FIG. It allows you to perform a registration operation.
