Description

TECHNICAL FIELD The present invention relates to a calling system in which call displays necessary for progress of work by calling operation of a calling machine arranged in an assembly line of a factory or the like are displayed on the side of a receiver and a portable display device.

Conventionally, in a factory that mass-produces products, workers assigned to each process of the assembly line attach, process, inspect, etc. parts to the equipment that flows through the assembly line by a belt conveyor or the like. We have adopted a line production system that performs the flow work of

In line production systems like this, in order to increase the production efficiency of products, it is necessary to smoothly support the workers assigned to each process of the assembly line, such as parts supply and inspection and repair. A calling system has been constructed in which line workers call production line managers, parts supply personnel, inspection and repair personnel, etc., for assistance.

In a conventional call system, a receiver receives a call signal by a call operation of a call machine arranged on an assembly line, and displays call contents corresponding to the call operation on a monitor device of the receiver. For example, when there is a shortage of parts on an assembly line or trouble such as a failure of work equipment occurs, the worker operates the caller corresponding to the shortage of parts or trouble, and transmits a call signal to the receiver. In addition to outputting a ring tone from the receiver, the call operation such as parts shortage or trouble occurrence is displayed on the monitor device in the order of call, and monitored by the production line manager, parts supply, inspection and repair etc. The call indication of the device is confirmed, and the necessary response is taken promptly and appropriately.

In addition, the paging machines used in conventional paging systems operate on battery power and require periodic charging and replacement, making maintenance difficult. The spread of battery-less callers that transmit call signals by self-power generation of electromagnetic induction that accompanies operation is also progressing.

JP 2017-168138 A JP 2015-061227 A JP 2019-193016 A JP 2010-263294 A JP 2014-42687 A Japanese Unexamined Patent Application Publication No. 2005-20348 JP 2010-51545 A U.S. Patent Application Publication No. 2014/0248804

However, in the conventional call system, the contents of the call made by operating 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. Persons in charge of parts supply, inspection and repair, etc. need to identify and respond to call indications related to themselves from among the call indications of the monitor device that are collectively displayed. It is necessary to check the call indications, and if there are a large number of call indications, it takes time and effort to confirm, which poses a problem of a large work load. In addition, some managers and persons in charge may be in charge of a plurality of processes, and since they have to check the call indications for the processes they are in charge of and respond to them, there is a problem that the work load is further increased.

In order to solve this problem, the person in charge of the support department has a portable display device such as a smartphone, and the call display displayed on the monitor device of the receiver is sent to the portable display device and displayed. It is conceivable that the call display can be confirmed by the manager or person in charge.

However, even if confirmation by the monitor device is not required and the call display can be confirmed at hand by the portable display device, the call display is similar to the call display displayed on the monitor device. are displayed together, it is necessary to check the call indications that are related to you from among them and take necessary measures. In addition, there is a concern that the information 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 portable displays are grouped, and the same group address is set for the callers and portable displays belonging to the same group. Then, the caller transmits 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, so that it is not affected by the call display of other groups. You can see the call indications that are relevant to you and respond quickly without having to wait.

However, if the caller is a battery-less caller that transmits a call signal by instantaneous electromagnetic induction self-generation generated by switch operation, the generated power is weak, so the call signal can only be sent for a short period of time, such as 1 ms. and the amount of data of the calling signal to be transmitted is restricted. In addition to this, if the group address to which one belongs is set, the data length becomes long, and there is a case where the generated power becomes insufficient during transmission, making it impossible to transmit a normal call signal.

Also, the group address to be set in the calling machine must be changed as necessary according to the change of the assembly line or the change of person in charge. However, since the battery-less paging machine can only obtain instantaneous power generation accompanying switch operation, it is not possible to immediately change the group address set at the manufacturing stage during operation. It is necessary to prepare facilities similar to those set in the stage. Therefore, when the grouping is changed, it is necessary to prepare and replace a new paging machine in which the group address after the change is set, or to prepare a facility for resetting the group address, which increases the operation cost. It will get bulky.

As another method of grouping the paging machines and the portable display machines, it is conceivable to assign different channel frequencies to each group. However, if the calling machine is previously provided with the function of switching and selecting the channel frequency so as to cope with group changes that are not always made, the configuration of the calling machine becomes complicated and the cost increases.

The present invention enables grouping without costing the caller when a call signal is transmitted from the caller and the call is displayed on the receiver and the portable receiver, and is required for the portable display. To provide a call system capable of displaying only call display of a group and easily responding to change of grouping without incurring operation cost.

To allow a manager or a person in charge of a plurality of groups to easily confirm the overall situation of the assembly line by displaying calls to the plurality of groups he or she is in charge of on one portable display device. be able to.

(Effect of preferential display of call frame)
In addition, by setting a priority display instruction in the table information of the receiver corresponding to a caller or call button with a high degree of importance such as an emergency call, for example, a plurality of call frames can already be displayed in order of call on the monitor unit. In this state, when a call signal is received from the caller or the call button of the caller to which the priority display instruction is set, the call frame corresponding to the priority display instruction takes precedence over the top position of the call frames already displayed. It is also displayed on the portable display device in conjunction with the display on the monitor, so that the person in charge who has the portable display device can know the emergency call and other calls of high importance and respond quickly. make it possible.

(Effect of Call Cancellation)
Further, among the table information of the receiver, some of the callers or the call buttons of the caller do not have a correspondence relationship set with the group, and the call cancellation instruction is set, so that the caller or the call button of the caller is set. Some of the provided call buttons can be made to function as call cancel buttons. The call frame displayed during calling on the display side can be easily deleted.

(Effect of Call Cancellation on Terminal Display)
In addition, the call display on the portable display can be canceled by performing a predetermined call cancellation operation to cancel the call frame information and erase the call frame. When the call is finished, the user can easily delete the call frames that have been dealt with by performing a call cancellation operation on his/her own portable display device. In conjunction with the call cancellation operation on the portable display, the call frame information on the receiver is canceled and the call frame on the monitor is erased. can be generated and stored in

(Effect of content of history frame information)
In addition, the history frame information includes a predetermined caller name (for example, assembly line name, etc.) indicating the caller corresponding to the canceled call frame information, and the group to which the called portable display device belongs. In addition to the specified group name (e.g., XX group, XX department), as additional information accompanying the cancellation, including the time when the call was completed and the name of the person in charge who responded, who responded to the call indication and how can be grasped simply and easily.

(Effects of calling button and history button on mobile display)
In addition, the portable display device has a calling button and a history button on the screen, etc. Normally, by operating the calling button, the call frame before erasing is displayed after receiving the call relay signal. On the other hand, by operating the history button as necessary, the history frame information corresponding to the deleted handled call frame information is displayed as a history frame, and the past calls that have been handled and their handling status are displayed. It is easy to confirm.

(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 is not set to correspond to the group, and an 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 erroneous operation can be prevented.

(Effect of additional registration contents of table information)
Further, the table information of the receiver is further set with the display color and ringing tone of the call frame corresponding to the call button of the calling machine or the ringing machine, and the display color and the ringing tone are set. When a call signal is received from the call button, the call frame is displayed in the display color obtained from the table information and the ringing sound obtained from the table information is output, so that the call frame displayed on the receiver and portable display is displayed. , easily distinguishable and audible.

(Effect of wireless network)
Also, the plurality of callers and the receiver are connected via a first wireless network, the receiver and the plurality of portable displays are connected via a second wireless network, and the first wireless network is connected to a predetermined specific wireless network. A single channel frequency in low power communication is used to transmit ringing signals from a plurality of pagers to a receiver, and a second wireless network uses a predetermined wireless local area network (wireless LAN) to the receiver. By transmitting and receiving signals between and a plurality of mobile display devices, for example, the first wireless network uses one channel of specific low-power communication in the 920 MHz band, so that all callers have the same channel frequency. To reduce the cost by simplifying the structure of a caller which operates by instantaneous electromagnetic induction power generation accompanying the operation of a call button and transmits a 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 portable display device, or a known short-range wireless communication such as Bluetooth (registered trademark). Therefore, a simple and reliable communication connection can be established between the receiver and the portable display device through a wireless line.

An embodiment of a call system according to the present invention will be described in detail below with reference to the drawings. In addition, this invention is not limited by the following embodiments.

[Basic concept of the embodiment]
Embodiments generally relate to paging systems. A calling system is a system in which when a worker on the assembly line of a factory performs a call operation on a caller, the call is displayed on the receiver and portable display device, and the person in charge of the called party can proceed with the work. It is a system for making the necessary response to such as. Here, "call display" means displaying information indicating predetermined call content on a receiver or portable display device, and the type and form of the call display are arbitrary. means that the "call frame" is displayed on the receiver or the portable display based on the "call frame information" indicating the specific call content.

The paging system of this embodiment includes a plurality of paging devices, a receiver having a monitor section, and a plurality of portable display devices.

A "caller" is, for example, placed in the vicinity of a worker placed in each process of an assembly line, operates by instantaneous electromagnetic induction power generation accompanying the operation of a call button, and sends a call signal to a receiver. The number of call buttons may be plural, and the number is arbitrary. Here, "electromagnetic induction power generation" refers to the mechanical movement associated with the operation of a call button, for example, to move an induction coil and a permanent magnet relative to each other, and to generate electric energy by changing the magnetic flux passing through the induction coil. Since it is self-powered, it realizes a so-called battery-less paging machine that does not require a battery power source.

A "call signal" is a signal indicating that a call button of a call machine has been operated, and although the signal format of the call signal is arbitrary, information that enables identification of the call machine or the call button of the call machine. contains Information for identifying the calling machine includes, for example, an address set for each calling machine, and information for identifying the call button of the calling machine includes, for example, a 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 numbers, and is a concept including identifiers, identification codes, identification codes, addresses, and the like. . The call signal is a signal that includes information specifying the caller by including the call button number, but does not include information specifying the callee, and the callee is specified by a receiver, which will be described later. be.

"Receiver" means the correspondence relationship between the caller and the callee group, or the caller It is provided with table information that sets the corresponding relationship between the call button of the machine and the group to be called. Generate call frame information for displaying the destination group name, etc., display the call frame on the monitor unit, generate a call relay signal including the call frame information specifying the call destination group, and send it to a plurality of portable display devices. is to be sent.

Here, the "calling frame information designating the group of the called party" is the information of the calling frame including the "group of the called party" which is the information for identifying the group of the called party. is a concept including group address, group name, identifier, identification code, identification code, and the like.

Also, "table information" is information registered for each calling machine, for example, table information in which the correspondence between caller name, call button number, and callee group is registered, and the concept includes a lookup table. , and is not limited to the table format, and includes an appropriate information format for registering the correspondence relationship. The "call frame information" is information for displaying the contents of the call from the calling machine. This is information including call frame image data for displaying the name, elapsed time from call, etc. in one call frame (display frame) on the screen. In the table information, for example, the display color and the type of ringing tone are registered in advance corresponding to the call button number. A ringing tone is output from the monitor section based on the table information.

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 is registered in advance. 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 a predetermined top position of the monitor unit, and in conjunction with this, the terminal display also corresponds to the priority display instruction. A call frame is displayed at a predetermined head position.

Also, the "monitor part" is to display the contents of the call (call frame) indicating what kind of call was received from the calling machine. It is a concept that includes

A “portable display device” is, for example, a portable display device that is carried by a person in charge of a department that supports maintenance inspections, etc. in response to insufficient supply of parts or the occurrence of defects in an assembly line equipped with a calling machine. is a mobile device with a display such as a smartphone, and is grouped by selecting and registering the group to which the person in charge belongs in advance. The call frame is displayed on the display based on the call frame information included in the call relay signal designating the callee group. The portable display device allows selection and registration of one or a plurality of groups to which the user belongs. In addition to selecting and registering one or a plurality of groups, the portable display device is also provided with a function of collectively selecting and registering all groups, for example.

On the other hand, the receiver can cause the caller or some of the call buttons provided on the caller to function as a call cancel button to cancel the call. For this reason, in the table information of the receiver, a call cancel instruction is registered in advance corresponding to the call button number of the call machine or the call button of the call machine to be used as the call cancel button. When a call cancellation instruction is acquired by referring to the table information by the button number, the call frame information of the corresponding monitor unit is canceled, the call frame is erased, and the call relay signal excluding the call frame information corresponding to the erased call frame is transmitted to the mobile phone. By sending this to the display, the call frame that has been canceled due to the updated display on the terminal display is deleted. The call cancellation instruction includes the concept of a call cancellation command or a call cancellation instruction.

Here, the receiver displays a call frame on the monitor unit and also displays the same call frame on one or a plurality of portable display devices connected to the receiver. is performed, the addition, change, and deletion of the call frame are performed on the portable display in conjunction with this. In this way, the display control for interlocking the display of the call frame on the monitor unit and the display of the call frame on one or a plurality of portable display devices by the receiver is, for example, so-called one-to-n screen display mirroring, screen display synchronization, or screen display synchronization. It includes the concept of sharing.

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

Further, if there is an unused caller or call button among a plurality of callers or call buttons provided on the caller, the receiver can disable the unused caller or call button. For this reason, in the table information of the receiver, a call button invalidation instruction is registered in advance corresponding to the call button number of the call button of the call machine or the call button of the call machine which is not used, for example, and the call of the received call signal is registered. When the call invalidation button instruction is obtained by referring to the table information by the button number, the processing is invalidated and nothing is performed. Note that the call button disable instruction includes the concept of a call button disable command or a call button disable instruction.

Also, the plurality of callers and the receiver are connected via a first wireless network, and the receiver and the plurality of portable displays are connected via a 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. It uses one channel frequency of specific low power communication. A "second wireless network" is a network for transmitting and receiving signals between a receiver and a plurality of terminal displays using a predetermined wireless local area network (wireless LAN) or short-range wireless network. For example, the concept includes wireless networks such as WiFi (registered trademark) and Bluetooth (registered trademark) provided in smartphones used as portable display devices.

Specific embodiments will be described below. In the embodiment shown below, a plurality of callers are arranged on an assembly line in a factory, a plurality of terminal displays are grouped into groups G1 and G2, and four call buttons are provided on the callers. I will explain the case where

[a. Overview of calling system]
FIG. 1 is an explanatory diagram showing the outline of the calling system, and takes the case of applying it to a factory assembly line as an example. The paging system of this embodiment includes a plurality of paging devices 10, a first wireless network 14, a receiver 16, a monitor device 18, a second wireless network 20, a plurality of portable display devices 22, a setting device 24, and a history collection device. 26. Note that the setting device 24 and the history collection device 26 are configured to be provided as necessary.

The calling machine 10 is arranged near the workers who are arranged in each process of the assembly line. For example, the assembly line consists of a first assembly line L1 and a second assembly line L2. The first assembly line L1 is divided into, for example, a first process L1-1 and a second process L1-2, and workers 15a and 15b are assigned to each process. A machine 10 is arranged. The second assembly line L2 is also divided into, for example, a first process L2-1 and a second process L2-2, and workers 15c and 15d are assigned to each process. A calling machine 10 is arranged.

The caller 10 has, for example, four call buttons 12a, 12b, 12c and 12d. Note that the number of call buttons is arbitrary. When any one of the call buttons 12a to 12d is pressed, the built-in call button switch is turned on, receives electric power generated by instantaneous electromagnetic induction generation accompanying the pressing operation, and operates to transmit the call signal E1 to the first wireless network 14. to the receiver 16 via. The call signal E1 contains 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 paging machine 10, generates 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 tone is output from the speaker of the monitor device 18 to indicate that there is a call. Further, the receiver 16 transmits a call relay signal E2 designating a callee group to the connected portable display device 22 via the second wireless network 20 based on the reception of the call signal E1. The timing of transmission of the paging relay signal E2 from the receiver 16 is arbitrary, for example, at each predetermined period or at each occurrence of an event such as addition, change, or deletion of a paging frame.

Here, the portable display devices 22 are grouped into, for example, a group G1 for parts supply and a group G2 for maintenance and inspection in response to calls from the workers 15a to 15b of the first and second assembly lines L1 and L2. there is Three persons in charge 25a, 25b, and 25c belong to group G1, and two persons in charge 25c and 25d belong to group G2, each of which has a portable display device 22. FIG. The person in charge 25c is the general person in charge who belongs to both groups G1 and G2.

In correspondence with the grouping of the portable display devices 22, the receiver 16 provides, for each address of the calling device 10, a caller name indicating the installation location of the calling device 10, and a group G1 of the called party to which the portable display device 22 belongs. , and G2 are registered in advance as table information to be clarified later. For example, group G1 is registered corresponding to the call button number of call button 12a in calling machine 10, and group G2 is registered corresponding to the call button number of call button 12b. Therefore, the call button 12a of the calling machine 10 functions as the call button for the group G1, and the call button 12b functions as the call button for the group G2.

When the receiver 16 receives the call signal E1 from the calling machine 10, the receiver 16 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. , a call relay signal E2 including call frame information designating the group G1 or G2 of the called party is transmitted to all terminal callers 22 in connection.

The portable display device 22 is, for example, a smart phone, and the groups G1 and/or G2 to which it belongs are set in advance before operation. For example, group G1 is set for the portable displays 22 of the persons in charge 25a and 25b, groups G1 and G2 are set for the portable display 22 of the person in charge 25c, and group G2 is set for the portable display 22 of the person in charge 25d. is set. Therefore, the portable display device 22 displays a call frame on the display based on the call frame information specifying the call destination group G1 or G2 that matches the group G1 or G2 to which the mobile display device 22 belongs, which is included in the received call relay signal E2. do. As a result, the call frames for all groups G1 and G2 are displayed on the monitor device 18 connected to the receiver 16, while the portable display device 22 displays the call frames for the groups G1 and/or G2 to which the user belongs. will be displayed.

Further, in the table information of the receiver 16, it is possible to register all groups as the callee group corresponding to the call button number of the call button 12c of the caller 10. FIG. As a result, the receiver 16 can cause the call button 12c of the caller 10 to function as an all-group call button.

Also, 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 with a high degree of urgency. As a result, when the receiver 16 receives a call signal including the call button number for which the priority display instruction is registered in a state in which a plurality of call frames are displayed on the monitor device 18 in call order, the receiver 16 displays the call frame on the monitor device 18 . can be displayed at the beginning of a call frame already displayed in the . Along with this, on the portable display device 22 as well, in conjunction with the display on the monitor device 18, the call frame of the call button number for which the priority display instruction is registered is displayed at the top position.

Also, in the table information of the receiver 16, a "call cancellation instruction" is registered corresponding to the call button number of the call button 12d of the caller 10. FIG. As a result, the receiver 16 can cause the call button 12d of the caller 10 to function as a call cancel button. For example, after the operator performs the calling operation, the call can be canceled by operating the call button 12d of the calling machine 10 when the person in charge of the called party no longer needs to respond or the operator makes an erroneous operation.

On the other hand, on the portable display device 22 as well, it is possible to cancel the call and erase the display of the call frame by performing a predetermined call cancellation operation. Cancellation of the call by the portable display device 22 is an operation performed when the person in charge who received the call goes to the caller and completes the response such as parts replenishment or inspection and repair. 22 transmits a call cancellation notification signal E3 to the receiver 16 via the second wireless network 20; This call cancellation notification signal E3 includes time information on which the response has been completed, the name of the corresponding person in charge, and the like. When the receiver 16 receives the call cancellation notification signal E3 from the portable display device 22, it deletes the corresponding call frame displayed on the monitor device 18, and also generates history frame information corresponding to the deleted call frame. memorize. This history frame information includes the name of the caller, the group name of the called party, the time when the call was completed, and the name of the corresponding person in charge.

Further, when there is an unused call button in the calling machine 10, the table information of the receiver 16 registers "call button disable instruction" corresponding to the call button number of the unused call button. As a result, even if the receiver 16 erroneously operates a call button that is not used in the calling machine 10, the receiver 16 can function as an invalid call button in which no processing is performed on the receiver 16 side.

The setting device 24 is connected to the receiver 16 by a signal cable or the like, and performs operations for registering table information provided in the receiver 16 . For this reason, the receiver 16 has a server section for downloading the registration screen to the setting device 24, and the setting device 24 downloads the registration screen from the receiver 16 by the browser section, and performs necessary registration operations. The registration operation using the registration screen by the setting device 24 includes, for each calling device 10, registration of the caller name, the called group name, the called group corresponding to the call button number, all groups, or a call cancellation instruction. It is a thing.

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

In FIG. 2, when a worker 15a assigned to the first process L1-1 of the first assembly line L1 operates the call button 12a of his own calling machine 10 to call the group G1 due to shortage of parts, a call signal E1 is generated. -1 is sent to receiver 16 .

Upon receipt of the call signal E1-1, the receiver 16 refers to the table information 48, acquires the caller name corresponding to the caller address, the callee group G1 corresponding to the call button number, etc., and sets the call frame. Information is generated, and the call frame 28-1 is displayed on the monitor device 18 based on this call frame information. The call frame 28-1 shows the callee group G1 and the caller first assembly line first process L1-1. Although the time elapsed since the call signal E1-1 was received is also displayed in the call frame 28-1, it is omitted. Further, the receiver 16 generates a call relay signal including the call frame information of the call frame 28-1 designating the call destination group G1, and displays the mobile displays of all the persons in charge 25a to 25d connected to the receiver 16. 22.

The call relay signal specifying the group G1 transmitted from the receiver 16 is received by the portable displays 22 of all the persons in charge 25a to 25d, and the portable displays 22 of the persons in charge 25a, 25b, 25c of the group G1 display their own The call frame 28-1 of the call frame information specifying the group G1 to which it belongs is displayed. 28-1 is not displayed.

Subsequently, when the worker 15c assigned to the first process L2-1 of the second assembly line L2 operates the call button 12b of his own caller 10 due to equipment failure or the like to call the group G2, a call signal is generated. E1-2 is sent 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 callee group G2 corresponding to the call button number, etc., and generates call frame information. Then, a call frame 28-2 is displayed on the monitor device 18 based on this call frame information. In the call frame 28-2, the called group G2 and the called second assembly line first process L2-1 are displayed. In addition, the receiver 16 transmits a call relay signal including the call frame information of the call frame 28-2 designating the call group G2 and the call frame information of the call frame 28-1 designating the call group G1 which is already being called. It is generated and transmitted to the portable displays 22 of all persons in charge 25a to 25d connected to the receiver 16. FIG.

The portable display devices 22 of the persons in charge 25a, 25b, and 25c of the group G1 update and display the call frame information 28-1 specifying the group G1 contained in the received call relay signal, but the group G2 is displayed. The call frame 28-2 of the designated call frame information is not displayed.

Also, the mobile display devices 22 of the persons in charge 25c, 25c belonging to the group G2 display the call frame information 28-2 specifying the group G2 to which they belong, which is included in the call relay signal received from the receiver 16. to display anew. As a result, on the terminal display 22 of the person in charge 25c who belongs to both groups G1 and G2, the call frame 28-1 of the call frame information specifying group G1 and the call frame 28 of the call frame information specifying group G2 are displayed. -2 are displayed side by side in the order received.

[c. Configuration of calling system]
Next, based on FIG. 3, the configurations of the calling machine, the receiver and the portable display which constitute the calling system will be described in more detail.

[d. caller]
The caller 10 transmits a call signal by operating a call button, and its function, configuration and structure are arbitrary. It is composed of button switches 30a to 30d, a call button control section 32, a transmission section 34 to which an antenna 35 is connected, and an electromagnetic induction power generation section 33. FIG.

The call button switches 30a to 30d close contacts and output an ON signal by pressing the call buttons 12a to 12d. For example, they have a seesaw structure. When you release the push, the force of the spring returns and turns off.

The call button control unit 32 generates a call signal E1 in a predetermined format and outputs it to the transmission unit 34 when an ON signal is input by operating one of the call button switches 30a to 30d. The signal format of the call signal E1 is arbitrary, but as shown in FIG. 4A, for example, it consists of a caller address, a call button number, radio wave intensity, a checksum CK, a delimiter, and the like.

The transmission unit 34 wirelessly transmits a call signal from the antenna 35, and the communication method is arbitrary. to send a ringing signal. Note that the use of specific low-power communication other than the 920 MHz band is not prohibited.

The electromagnetic induction power generation unit 33 supplies power to the call button control unit 32 and the transmission unit 34 by instantaneous electromagnetic induction power generation accompanying the ON operation of any one of the call button switches 30a to 30d by the call buttons 12a to 12d. to transmit a ringing signal. For example, when one 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 power. The power generation of the electromagnetic induction power generation unit 33 is instantaneous power generation for which the operating power is obtained for about 1 ms. For this reason, the signal length of the call signal that can be transmitted by the instantaneous operation of about 1 ms of the call button control section 32 and the transmission section 34 is restricted to about 20 bytes when the baud rate is 57.6 kbps, for example.

[e. Receiving machine]
The receiver 16 receives the call signal from the paging machine 10, generates call frame information of predetermined call content, displays the call frame on the connected monitor device 18 based on the call frame information, and calls from the speaker. It outputs a sound and also transmits a call relay signal including call frame information designating a called party group to the portable display device 22. Its function and configuration are arbitrary, but for example, as shown in FIG. , a receiver controller 36, a receiver 40 to which an antenna 38 is connected, and a transmitter/receiver 42 to which an antenna 44 is connected. For example, the connection with the monitor device is an HDMI (registered trademark) cable, and the connection by the HDMI (registered trademark) cable is based on the High Definition Multimedia Interface standard, and the image data (image content) and audio data can be transferred.

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

The transmitting/receiving unit 42 transmits/receives various signals via the second wireless network 20, and functions as, for example, a wireless router or an access point. 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 having a CPU, a memory, and various input/output ports. A portion 52 is provided.

A pager address is a unique address for identifying a plurality of pagers 10 shown in FIG. The caller name is information indicating the place where the caller 10 is installed. Then, the caller name of the caller address A1 is "first assembly line first process L1-1", and the caller name of the caller address A2 is "first assembly line second process L1-2".

As the call button number, call button numbers CB1 to CB4 unique to the call buttons 12a to 12d provided in the calling machine 10 are set. Note that CB1 to CB4 are merely notations, and in reality, predetermined bit codes are set.

The call target is information based on designating call destination groups corresponding to the call button numbers CB1 to CB4. , 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. Groups G1 and G2 each mean a unique group address.

In addition to the call destination group, "all groups" are registered as call destinations corresponding to the call button number CB3. Further, a "call cancellation instruction" is registered corresponding to the call button number CB4. In addition to this, it is possible to register a "call button invalidation instruction" corresponding to the call button number of the unused call button.

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

As for the display color, the display color of the call frame displayed on the monitor device 18 or the portable display device 22 is registered in correspondence with, for example, the callee group. The call frame for group G1 is "green", the call frame for group G2 is "blue", and the call frame for all groups is "red". ”. This makes it possible to easily distinguish between call frames belonging to the same group by the same display color.

The ringing tone is for registering the type of notification sound when a calling signal is received, and the display sound is arbitrary. All groups are "win-win", and the "call cancellation instruction" is also "ping-pong". This makes it possible to easily distinguish between calls belonging to the same group by the same ringing tone.

(e3. Call display by call frame)
The call frame 28 displayed on the monitor device 18 when the receiver 16 receives a call signal may have any shape and structure, but may be, for example, a horizontally long rectangular shape as shown in FIG. 6(A). , the group name 68 to be called is arranged in the upper row, the caller name 70 is arranged in the middle row, and the elapsed time after receiving the call signal is arranged as the time information 72 in the lower row.
