[3. Transition state and database]
Next, the state transition and the database relating to the state transition will be described with reference to the drawings.

(3.1 State transition)
5 and 8 are schematic diagrams illustrating an example of state transition. 6 and 9 are schematic diagrams illustrating an example of an image group corresponding to each state. FIG. 7 is a schematic diagram illustrating an example of an image group corresponding to a state.

  As shown in FIG. 5, for example, when there are six states in the management target, a transition from a certain state (one state) to a predetermined state is indicated. “Reset” corresponds to a state reset function. It shows that each state can be changed to, for example, “state 1” by selecting and pressing the operation button 34a.

  As shown in FIG. 5, for example, in the case of “state 1”, the state transition destination can transition to “state 2”. In the case of “state 2”, transition to “state 3”, “state 4”, “state 5”, and “state 1” (by reset) is possible. In the case of “state 3”, transition to “state 4” and “state 1” (by reset) is possible. In the case of “state 4”, transition to “state 5”, “state 6”, and “state 1” (by reset) is possible. In the case of “state 5”, transition can be made to “state 6” and “state 1” (by reset). In the case of “state 6”, transition to “state 1” is possible (reset or switching to the next screen).

  The transition destination state and the transition source state of these states form a state group (an example of a state group formed by one state and a state that can transition from the one state to the next).

  As shown in FIG. 6, an image is set corresponding to each state of the state group, and an image group is formed for each state. Here, the image of the image group is an example of each presentation information for presenting to the user corresponding to each state of the state group.

  As shown in FIG. 7, the images in the image group are sequentially displayed on the display unit 33 by the operation of the operation button 34 a. In the state transition, when the operation button 34a is operated, the display image on the display unit 33 is switched, and when the operation button 34a is confirmed, confirmation information is transmitted from the information display terminal device 30 to the display server device 10. Then, in the state management server device such as the display server device 10, the state transitions to the confirmed state.

  In addition to the operation of the operation button 34 a of the information display terminal device 30, the state transition may be an automatic transition by the display server device 10 based on a transition route, or a transition by a notification from the upper server device 20. For example, as shown in FIG. 8, for example, in the case of five states, by the transition by the operation of the operation button 34 a of the information display terminal device 30, the automatic transition by the display server device 10, and the notification from the upper server device 20 A combination of transitions is mentioned. Note that the operation of the operation button 34a of the information display terminal device 30 (for example, pressing), the transition route determination by the display server device 10 (automatic transition), and the notification from the upper server device 20 cause a state transition. Transition conditions.

  Then, corresponding to the state transition diagram of FIG. 8, as shown in FIG. 9, the state “ST-001”, the state “ST-002”, the state “ST-003”, the state “ST-004”, and In each state “ST-005”, a state group and an image group are set.

  When the state is “ST-002”, the state group is the state “ST-001”, the state “ST-002”, and the state “ST-003”, but the image group is the state “ST-001”. "And an image corresponding to the state" ST-002 ". When the state is “ST-002”, the state transitions to the state “ST-003” by the notification from the higher-level server device 20, and it is not necessary to switch the image by operating the operation button 34 a of the information display terminal device 30. The image “image3” corresponding to “ST-003” has been removed.

  In the case of state “ST-004”, the state group is state “ST-001”, state “ST-003”, state “ST-004”, and state “ST-005”, but the image group Is only an image corresponding to the state “ST-004”. In the case of the state “ST-004”, depending on the transition route, the state automatically changes to the state “ST-003” or the state “ST-005”, and the operation button 34a of the information display terminal device 30 Since there is no need to switch images by operation, it corresponds to image “image3” corresponding to state “ST-003”, image “imgage5” corresponding to state “ST-005”, and state “ST-001” due to reset operation. The image “image1” to be removed has been removed.

(3.2 Database)
Next, a database corresponding to the state transition diagram of FIG. 8 will be described with reference to FIGS.

  10, 11, 13, and 15 are schematic diagrams illustrating an example of a database constructed in the storage unit of the display server device 10. FIG. 14 is a schematic diagram illustrating an example of a storage index corresponding to the memory area of the information display terminal device 30. An example based on the state transition diagram of FIG. 8 will be described.

  As shown in FIG. 10, the state information DB 12a stores a transition condition, a transition destination, a transition source, and the like in association with a state ID that specifies each state.

  Here, with the transition condition “automatic transition” in the state ID “ST-004”, the transition destination “ST-005” and the transition source “ST-003” are changed from the state “ST-003” to the state “ST-004”. When the transition is made, it indicates that the transition is made immediately to the state “ST-005”. In addition, the transition destination “ST-003” in the transition condition “server notification” in the state ID “ST-002” indicates, for example, information “with order” from the upper server device 20 as a predetermined notification. Indicates that the state transits to “ST-003”.

  As shown in FIG. 11, in the state information DB 12a or the display information DB 12b, information on a base image, which is an image of a basic framework associated with a state ID specifying each state and displayed on the display unit 33, is displayed. A variable part format indicating information that changes depending on the state of the base image is recorded as a state table. The state table is a table that stores information for generating an image to be displayed in each state.

  Here, for example, as shown in FIG. 12, the base image is an image of a basic framework displayed on the display unit 33 such as a shelf code and a component code. The variable part format information is a format describing the base image and variable information to be superimposed. The variable part format information is, for example, information displayed on the display unit 33 in FIG. 4 from which the base image information is removed, and the position, size, and size of characters and images displayed in the variable value area are XML. (Extensible Markup Language) format information. Here, the information of the base image and the variable part format is an example of each piece of presentation information for presentation to the user corresponding to each state of the state group.

  As shown in FIG. 13, a database of image groups corresponding to each state is constructed in the state information DB 12a. In the state information DB 12a, as an image group table, an image ID (state ID) associated with each state for each index and a flag indicating whether display is not displayed for each index are associated with each state. An initial display index storing an image (state) to be displayed as a default in a certain state is stored.

  For example, in the case of the state “ST-001”, the state “ST-001” corresponding to the image “image1” is associated with the image group in the “Index1” column, and the image “image2” is associated with the “Index2” column. A state ID “ST-004” corresponding to the image “image4” is stored in the corresponding state ID “ST-002” and “Index3” columns.

  In addition, the initial display index is an index for indicating a place where an image (state) to be displayed by default in a certain state is stored. For example, when transitioning to the state of ST-001, the initial display index is Index1. , ST-001 stored in the memory corresponding to Index1 is displayed.

  Here, as shown in FIG. 14, the indexes in the “Index1” column, the “Index2” column, and the “Index3” column store images indicating the state in the storage unit 32 or the RAM 36c of the information display terminal device 30. The memory area allocated for this purpose is shown. These indexes are used for the display server device 10 (or the host server device 20) to grasp and manage all the memory areas of the information display terminal device 30 in which images are stored. These indexes are common to each information display terminal device 30.

  In the index column, blank information to be deleted and null information to be hidden may be stored according to the state of the image data in the storage unit 32. Even if image data exists in the storage unit 32, a flag indicating whether to perform display may be provided.

  As shown in FIG. 15, the state information DB 12 a is a table storing basic information of the information display terminal device 30, and is associated with the terminal ID of the information display terminal device 30, so that the information display terminal device 30 is positioned. The access point ID of the access point determined to belong to, the status of the information display terminal device 30, the status of the battery, the management target ID of the management target to which the information display terminal device 30 is attached, the information display terminal device 30 The state ID indicating the state of the transition state shown, the last communication time with the display server device 10, and the like are stored.

[5. Operation of state management system 1]
Next, operation | movement of the state management system 1 which concerns on one Embodiment of this invention is demonstrated using figures.

(5.1 Operation Example of Information Display Terminal Device 30)
First, an operation example of the information display terminal device 30 will be described with reference to FIG.

  FIG. 20 is a flowchart illustrating an operation example of the information display terminal device 30.

  The information display terminal device 30 is set in the article 5, and the information display terminal device 30 is turned on as shown in FIG.

  Next, the state management system 1 displays the image stored in the storage unit 32 of the information display terminal device 30 (step S1). Specifically, the system control unit 36 of the information display terminal device 30 displays the image stored in the storage unit 32.

  Next, the state management system 1 notifies the display server device 10 of activation (step S2). Specifically, as shown in FIG. 18, the system control unit 36 of the information display terminal device 30 transmits a communication packet including the terminal ID of the information display terminal device 30 itself, the access point ID to which the information display terminal device 30 belongs.

  Next, the state management system 1 determines whether there is an event (step S3). Specifically, the system control unit 36 of the information display terminal device 30 determines whether there is an event of the information display terminal device 30 (for example, the operation button 34a is pressed) or an event from the display server device 10. It is determined whether there is (for example, transmission information of an image group). In addition, as an event of the information display terminal device 30, depending on how the operation button 34a is selected and pressed, the next screen switching event, the reverse screen switching event, the screen finalization event, and the state before the previous transition are restored. An event, an event for transitioning to a predetermined state, and an event for turning on / off the power source are included.

  When there is no event (step S3; NO), the information display terminal device 30 stands by until there is an event.

  When there is an event (step S3; YES), the state management system 1 determines whether the event is from the display server device 10 (step S4). Specifically, the system control unit 36 of the information display terminal device 30 determines whether it is image group transmission information from the display server device 10.

  If the event is from the display server device 10 (step S4; YES), the state management system 1 receives an image group as an example of the state group (step S5). Specifically, the system control unit 36 of the information display terminal device 30 receives data of a communication packet including an index associated with the state group information from the display server device 10 as illustrated in FIG.

  In this way, the information display terminal device 30 acquires state group information for acquiring information on a state group formed by one state and a state that can be transited from the one state to the next in the state transition indicating the state transition in the management target. It functions as an example of means. The information display terminal device 30 functions as an example of a state group acquisition unit that acquires information on a state group including the index.

  Next, the state management system 1 stores the received image group in the storage unit 32 of the information display terminal device 30 (step S6). Specifically, the system control unit 36 of the information display terminal device 30 extracts image data of the image group from the received communication packet and stores it in the storage unit 32.

  If it is not an event from the display server device 10 (step S4; NO), that is, if it is an event of the information display terminal device 30, the state management system 1 determines whether it is an image switching event (step S7). ). Specifically, the system control unit 36 of the information display terminal device 30 determines whether the operation of the operation button 34a is an image switching event.

  If it is an image switching event (step S7; YES), the state management system 1 updates the index (step S8). Specifically, the system control unit 36 of the information display terminal device 30 changes the index value in the storage unit 32 to an index value corresponding to the displayed image.

  If the index is null information or blank information, the index value may be changed to the following value.

  Next, the state management system 1 acquires an index image from the storage unit 32 (step S9). Specifically, the system control unit 36 of the information display terminal device 30 acquires an image corresponding to the index from the memory area of the storage unit 32 corresponding to the index.

  Next, the state management system 1 updates the display image (step S10). Specifically, the system control unit 36 of the information display terminal device 30 displays the acquired image on the display unit 33. After the display, the information display terminal device 30 returns to the process of step 3.

  Thus, the information display terminal device 30 functions as an example of a display unit that displays one presentation information among the pieces of presentation information to be presented to the user corresponding to each state of the state group.

  When the event is not an image switching event (step S7; NO), the state management system 1 determines whether the event is an image determination event (step S11). Specifically, the system control unit 36 of the information display terminal device 30 determines whether or not the operation of the operation button 34a is an image determination event.

  If the event is an image determination event (step S11; YES), the state management system 1 transmits the index information of the image being displayed to the display server device 10 (step S12). Specifically, the system control unit 36 of the information display terminal device 30 sets the index information to the display server device 10 through the communication unit 31. More specifically, as shown in FIG. 19, the system control unit 36 performs communication including the terminal ID of the information display terminal device 30 itself, the transition source image index corresponding to the current state, and the transition destination image index. The packet is set as the display server device 10. After the transmission, the information display terminal device 30 returns to the process of step 3.

  If the event is not an image determination event (step S11; NO), the state management system 1 performs other processing (step S13). Specifically, the system control unit 36 of the information display terminal device 30 determines whether the event is another event such as a power ON / OFF event, and performs processing according to the determination. Then, after the other processing, the information display terminal device 30 returns to the processing in step 3.

(5.2 Operation Example of Display Server Device 10)
Next, an operation example of the display server device 10 will be described with reference to FIG.

  FIG. 21 is a flowchart illustrating an operation example of the display server device 10.

  First, the state management system 1 receives an activation notification of the information display terminal device 30. Specifically, the system control unit 16 of the display server device 10 receives the information of the activation notification transmitted from the information display terminal device 30 in the process of step S2 through the communication unit 11.

  Next, the state management system 1 transmits an initial state image to the information display terminal device 30 (step S20). Specifically, information on an image group including an initial state image corresponding to the management state of the information display terminal device 30 is transmitted to the information display terminal device 30. More specifically, the display server device 10 transmits communication packet data as shown in FIG. 17 to the information display terminal device 30. Here, in the communication packet, the initial display index first indicates the initial state image.

  Next, the state management system 1 determines whether there is an event (step S21). Specifically, it is determined whether or not the display server device 10 is an event from the host server device 20 or an event from the information display terminal device 30. As an event from the higher-level server device 20, notification from the higher-level server device 20 of information related to a management target in the entire system, such as ordering information, arrival information, and discharge information, can be given. An event from the information display terminal device 30 includes reception of a storage index corresponding to image confirmation in the information display terminal device 30 in the process of step S12.

  When there is no event (step S21; NO), the display server device 10 stands by until there is an event.

  If there is an event (step S21; YES), the state management system 1 determines whether the event is from the information display terminal device 30 (step S22). Specifically, the system control unit 16 of the display server device determines whether or not a storage index associated with the image confirmation of the information display terminal device 30 has been received.

  When the event is from the information display terminal device 30 (step S22; YES), the state management system 1 collates the received index with the database (step S23). Specifically, the system control unit 16 of the display server device 10 refers to the state information DB 12a as shown in FIG. 13 based on the transition source image index and the transition destination image index (storage index) of the communication packet in FIG. To do.

  Next, the state management system 1 acquires the state transition destination state from the database (step S24). Specifically, the system control unit 16 of the display server device 10 refers to the state information DB 12a as illustrated in FIG. 13 based on the transition source image index and the transition destination image index, and corresponds to the corresponding state ID (state transition The state ID of the previous state is specified. Referring to the state information DB 12a as shown in FIG. 15, the system control unit 16 of the display server device 10 grasps the state of the information display terminal device 30 based on the terminal ID. For example, in the case of the terminal ID “xxxxx1”, the system control unit 16 reads the record corresponding to the state ID “ST-001” with reference to the state information DB 12a as shown in FIG. If the received transition source image index is “Index1”, the current state is the state “ST-001”, and if the received transition destination image index is “Index2”, the transition destination state is If the state is “ST-002” and the received transition destination image index is “Index3”, the transition destination state is the state “ST-004”. Next, if the received transition destination image index is “Index2”, the state ID of the record of the terminal ID “xxxxx1” becomes the state “ST-002” in the state information DB 12a as shown in FIG. Alternatively, if the received transition destination image index is “Index3”, the state ID of the record of the terminal ID “xxxxx1” becomes the state “ST-004”.

  Since there may be an automatic transition, the system control unit 16 of the display server device 10 refers to the state information DB 12a as shown in FIG. 10, for example, the transition source is the state “ST-001”, and the state ID In the case of “ST-004”, the state ID of the record of the terminal ID “xxxxx1” becomes the state “ST-003”.

  As described above, the display server device 10 is an example of a state group specifying unit that specifies a state group formed by one state and a state that can be transited next from the one state in the state transition indicating the state transition in the management target. Function as.

  In addition, when it is not an event from the information display terminal device 30 (step S22; NO), that is, when it is an event from the upper server device 20, the display server device 10 performs the process of step S24.

  Next, the state management system 1 determines whether it is automatic transition (step S25). Specifically, the system control unit 16 of the display server device 10 refers to the state information DB 12a as shown in FIG. 10, and the transition condition is “automatic transition” based on the transition source image index and the transition destination image index. It is judged whether it corresponds to "." For example, when the state corresponding to the transition source image index is the state ID “ST-003” and the state corresponding to the transition destination image index is the state ID “ST-004”, the state information DB 12a as shown in FIG. It is determined that the state ID is “ST-004” and the automatic transition is made according to the transition condition column. In the case of an event from the upper server apparatus 20, the transition condition corresponds to “server notification”.

  When it is automatic transition (step S25; YES), the state management system 1 changes the state transition destination (step S26). Specifically, the system control unit 16 of the display server device 10 refers to the state information DB 12a as illustrated in FIG. 10 and acquires the state ID of the transition destination. For example, when the state corresponding to the transition source image index is the state ID “ST-003” and the state corresponding to the transition destination image index is the state ID “ST-004”, the state information DB 12a as shown in FIG. It can be seen that the state ID is “ST-004”, the transition source corresponds to “ST-003”, and the state ID of the next automatic transition destination state is “ST-005”. Then, the state transition destination is changed from the state ID “ST-004” to “ST-005”.

  Next, returning to the processing of step S25, the display server device 10 refers to the state information DB 12a as shown in FIG. 10 and determines whether or not the changed state transition destination state is an automatic transition. .

  If it is not automatic transition (step S25; NO), the state management system 1 acquires the state transition destination image group from the database (step S27). Specifically, the system control unit 16 of the display server device 10 refers to the state information DB 12a as illustrated in FIG. 13 and the state corresponding to each image in the image group based on the state ID of the state transition destination state. Get an ID. Then, the system control unit 16 refers to the state information DB 12a as illustrated in FIG. 11 and acquires image data (base image and variable unit format) based on each state ID of the image group.

  If the base image is already in the storage unit 32 of the information display terminal device 30, only the variable unit format may be transmitted. In this case, the transmission amount can be reduced. Only the image data of the difference image between the image group before the state transition and the image group after the state transition may be transmitted. In this case, the transmission amount can be reduced.

  Next, the state management system 1 transmits an image group to the information display terminal device 30 (step S28). Specifically, the system control unit 16 of the display server device 10 transmits the image group acquired from the database to the information display terminal device 30.

  Thus, the display server device 10 transmits each presentation information to be presented to the user corresponding to each state of the specified state group to an information display terminal device that displays the presentation information. It serves as an example.

  The state management system 1 may determine whether or not there is an image update before transmitting the image group. For example, if the image stored in the information display terminal device 30 has a common image in the image group before the state transition and the image group after the state transition, and the common image is not updated, the display server device 10 Does not have to transmit a common image. In this case, the transmission amount can be reduced.

  Next, the state management system 1 determines whether or not there is a notification to the higher level server device 20 (step S29). For example, when the state is waiting for delivery, information on whether or not there is a delivery of a part or the like is necessary in order to transition to the next state. In this way, the display server device 10 determines whether information from other than the information display terminal device 30 and the display server device 10 is necessary.

  When there is a notification in the upper server apparatus 20 (step S29; YES), the state management system 1 notifies the upper server apparatus 20 of the state transition (step S30). For example, when the status is waiting for delivery, information indicating that the status has transitioned to the delivered status is transmitted in order to notify the host server device 20 whether or not there is a delivery of a part or the like.

  After the process of step S30 or when there is no notification to the upper server apparatus 20 (step S29; NO), the display server apparatus 10 returns to the process of step S21.

  As described above, according to the present embodiment, in the state transition indicating the state transition in the management target, information on the state group formed by one state and a state that can be transited next from the one state is acquired, and each state group is obtained. Of each piece of presentation information to be presented to the user in correspondence with the state, one presentation information is displayed, and by switching the display of the presentation information, switching or display is limited to a state group that can transition from one state to the next. Therefore, information on a state that cannot be changed is not displayed, and it is possible to prevent a mistake in work on the management target.

  Further, since the state group is limited to a state group that can be transitioned from one state to the next, even if the state transition relation of the state is complicated, the input mechanism for selection when transitioning to the next state can be simplified. For example, it can be operated only with the operation button 34a. It takes no time for the user to use the device.

  As an example of a confirmation accepting unit that accepts confirmation of a state, when the operation button 34a is provided and information on a state group that can be transited next from the confirmed state is acquired, the user's intention is confirmed and the transition is made to the next state. As a result, malfunctions are reduced.

  Further, when switching the display of the presentation information based on the input from the button switch (operation button 34a) that receives the user input, the user can easily select the state by operating the button switch.

  Further, when the display of the presentation information is switched based on the pattern in which the button switch (operation button 34a) is pressed, it is possible to deal with the selection and determination of the state with a small number of button switches. Also, the number of parts can be reduced.

  In addition, an index indicating a memory area allocated to the memory of the information display terminal device, the information of the state group including the index is acquired, and the presentation information is stored in the memory area corresponding to the acquired index, the transmission The amount can be reduced. Furthermore, in this case, it can be realized with at least one input component (for example, the operation button 34a), and can be applied to a complicated transition diagram, taking into consideration the size and address of the memory area storing the image. It does not have to be. This can be realized on the state management server (display server device 10) side by grasping the current state (state ID) of each information display terminal device 30 as shown in FIG. This is because the index of the memory area of the image (state) stored in the information display terminal device 30 and the transition destination state (state ID) are linked from the state ID).

  When the information display terminal device 30 notifies the display server device 10 of a state transition by a button operation, as shown in FIG. 19, a transition source image index (number) representing a memory area in which the transition source image is stored, and The state transition can be notified only by transmitting two numbers so that a transition destination image index (number) representing a memory area in which the transition destination image is stored is transmitted together.

  In the transition diagram as shown in FIG. 8, when notifying the display server device 10 of the transition from ST-001 to ST-002, unlike the index, if it is a character, “transition from ST-001 to ST-002” If the number of characters (= data amount) is applied, and the image itself is transmitted, it is necessary to send two images of the transition source and the transition destination, which increases the data amount.

  In the case of transmitting a number called an index, what can be realized with at least one button for input in the information display terminal device 30 is stored in the memory area “10” even if the index is “10”, for example. Since it is only necessary to display and confirm the displayed image, it is not necessary to enter the number “10”, and an input device such as a numeric keypad is not necessary.

  The reason why even a more complicated transition diagram than FIG. 8 is applicable is that the information display terminal device 30 must store an image (state) regardless of how complicated the transition is. This is because the user can select and confirm an image without being aware of a complicated transition diagram. For example, even if there are 100 million states (ST-000000001 to ST-100000000) in total, if the number of states that can be transitioned from a certain state by button operation is 10 states at the maximum, the information display terminal device 30 is 10 pieces. Therefore, a large-capacity recording medium is unnecessary. Since the transition source index (for example, 01) and the transition destination index (for example, 08) may be used to notify the state transition, there is no relation even if the total number of states increases.

  Since the exchange of the state (image) between the state management server device (display server device 10) and the information display terminal device 30 uses all indexes, it is not necessary to be aware of the actual memory area. For this reason, the information display terminal device 30 can be operated in a mixed manner even if the memory areas of the new type and the old type are not compatible.

  In addition, the new information display terminal device 30 can be mixedly operated even when the display screens have different sizes (resolutions). Since the maximum size of image data is generally different when the resolution is different, the memory area to be stored is also different. For example, if the resolution is doubled (the maximum amount of data is 4 times), Index1 in FIG. 14 must be changed from 0x4000-0x41FF to 0x04000-0x107FF to secure the storage area, but the Index does not change. Therefore, the data format as shown in FIGS. 17 and 19 can be used as it is.

[6. Example of state transition]
Next, the state transition of inventory management, the state transition of manufacturing management, and the state transition of bed management such as a hospital will be described with reference to the drawings.

(6.1 Status transition of inventory management)
First, inventory management state transition will be described with reference to FIG.

  FIG. 22 is a schematic diagram illustrating an example of state transition in inventory management.

  As an example, description will be made using an example in which each information display terminal device 30 is installed in each storage box (article 5) for storing bolts as parts.

  As shown in FIG. 22, when the empty box in the state “ST01”, for example, the storage box is empty, the information display terminal device 30 displays the image group data of one state group in the state “ST01” in step S5. The image data of the empty box display screen is received. For example, on the display screen of the empty box, in the display as shown in FIG. 4, the code of the shelf code 33a is displayed, and various displays 33f “empty box” are displayed. Further, the image of the component is not yet displayed on the image 33e, and the specific contents of the component code 33b, the manufacturer code 33c, and the component name 33d are not displayed.

  Since the transition from the state “ST01” to the state “ST02” is a transition caused by a notification from the host server device 20, in the state “ST01”, an image that can be displayed on the information display terminal device 30 corresponds to the state “ST01”. Even if the operation button 34a is operated on the information display terminal device 30 with only the image to be displayed, the image corresponding to the next state is displayed or the transition does not move to the next state.

  The display server device 10 receives the information “waiting for delivery” from the higher-level server device 20, and in step S21, there is an event, and the state transition destination state is acquired in step S24. As shown in FIG. 22, since the transition from the state “ST01” to the state “ST02” is not an automatic transition, the display server device 10 determines in step S27 the state group (state) of the transition destination including the state “ST02”. ST02 ”, state“ ST03 ”, and state“ ST05 ”) are acquired, and are transmitted to the information display terminal device 30 in step S28.

  Next, the information display terminal device 30 stores the image group, and in the image corresponding to the state “ST02”, for example, in the display shown in FIG. 4, various displays 33f “4/1 delivery schedule”, image 33e, The contents of the part code 33b, the manufacturer code 33c, and the part name 33d are displayed.

  After the parts are delivered and the operator delivers the parts to the storage box, the operation button 34a is operated to switch the image (step S7). If the number of parts is greater than or equal to the predetermined number, the state "ST03" is supported. When the number of parts is smaller than the predetermined number, the image corresponding to the state “ST05” is confirmed (step S11).

  When the image corresponding to the state “ST03” is confirmed, the information display terminal device 30 automatically changes to the state “ST04”, and the information display terminal device 30 selects the image group corresponding to the state group (state “ST04” and state “ST05”). An image acquired from the display server device 10 and corresponding to the state “ST04” is displayed.

  When the number of parts in stock is less than the predetermined number, the operator confirms the image corresponding to the state “ST05”, and the information display terminal device 30 transmits information indicating that the stock is low to the display server device 10. Information indicating that the stock is low is transmitted from the display server device 10 to the upper server device 20, and the upper server device 20 operates the state management system 1 so as to prompt the purchaser to place an order.

  Next, the state automatically shifts to the state “ST06”, and the information display terminal device 30 acquires the image group corresponding to the state group (the state “ST06” and the state “ST09”) from the display server device 10, and the state “ST06 The image corresponding to “(various displays 33f“ stock is low ”) is displayed.

  When a part is ordered, the upper server apparatus 20 transmits information indicating that the part has been ordered to the display server apparatus 10, and the state transitions to the state "ST07". The information display terminal device 30 obtains an image group corresponding to the state group (state “ST07” and state “ST09”) from the display server device 10 and orders an image corresponding to the state “ST07” (various display 33f being ordered). + Inventory ") is displayed.

  Further, when the delivery date of the part is confirmed, the upper server apparatus 20 transmits information indicating that the delivery date is confirmed to the display server apparatus 10, and the state transitions to the state “ST08”. The information display terminal device 30 acquires an image group corresponding to the state group (state “ST08” and state “ST09”) from the display server device 10, and displays an image corresponding to the state “ST08” (various displays 33f ”5 / 1 delivery + low inventory ”).

  In the state “ST06”, the state “ST07”, and the state “ST08”, when the stock runs out, the operator confirms the image corresponding to the state “ST09”. When transitioning from state "ST06" to state "ST09", transition is automatically made to state "ST10". When transitioning from state "ST07" to state "ST09", transition is automatically made to state "ST11" and state "ST08" Automatically transitions to state “ST02” when transitioning from state to state “ST09”.

(6.2 Example of hospital bed management)
Next, the state transition of bed management in a hospital or the like will be described with reference to FIGS.

  FIG. 23 is a schematic diagram illustrating an example of an information display terminal device installed in a bed of a hospital or the like. FIG. 24 is a schematic diagram illustrating an example of state transition in bed management in a hospital or the like.

  As shown in FIG. 23, an information display terminal device 30 is installed on a hospital bed. Here, a bed code, a patient name, a doctor in charge, the number of days of hospitalization, a patient code, and the like are displayed on the display unit 33 of the information display terminal device 30. The information display terminal device 30 has three users: a patient, a nurse, and a cleaning staff.

  First, when the information display terminal device 30 is installed in the bed and activated, the state is “ST01” (in preparation), and the bed code and “in preparation” are displayed on the display unit 33. As shown in FIG. 24, the images that can be displayed on the display unit 33 are images corresponding to the state group, the state “ST01”, the state “ST02” (preparation completion notification), and the state “ST10” (failure notification), respectively. It is.

  Next, the cleaning staff prepares the bed and confirms the image corresponding to the state “ST02” in order to notify the host server 20 that the bed is ready. In addition, when there is an abnormality such as a failure in the equipment around the bed, the cleaning staff confirms the image corresponding to the state “ST10”.

  When the image corresponding to the state “ST02” is confirmed, the information display terminal device 30 automatically displays the image group corresponding to the state group (state “ST03”) by automatically transitioning to the state “ST03” (usable). An image acquired from the server device 10 and corresponding to the state “ST03” is displayed. The display unit 33 displays a bed code and “available”.

  When the patient is hospitalized, the upper server extracts available beds, sends patient information to the information display terminal device 30 of the corresponding bed, and changes from the state “ST03” (usable) to the state “ST04” (in use) ). The information display terminal device 30 acquires the image group corresponding to the state group (state “ST04”, state “ST05” (cleaning required notification) and state “ST10”) from the display server device 10, and enters the state “ST04”. A corresponding image (an image on which patient information is described) is displayed.

  A nurse or the like who has visited the bed looks at the state of the bed and, if cleaning is necessary, notifies the host server device 20 so that the nurse or the like confirms the image corresponding to the state “ST05”.

  When the image corresponding to the state “ST05” is confirmed, the information display terminal device 30 automatically changes to the state “ST06” (cleaning required), and the information display terminal device 30 displays the state group (state “ST06” and state “ST07” (cleaning permission). Notification)) is acquired from the display server device 10 and an image corresponding to the state “ST06” is displayed. Information indicating that cleaning is necessary is displayed on the display unit 33. The host server device 20 notifies the cleaning staff of a rough time zone and place where cleaning can be performed from the patient's schedule.

  The host server device 20 recognizes that this process has been completed by another means, and displays an image for the next C process (an image corresponding to the state “ST03”) via the display server device 10 as an information display terminal device. 30.

  In the state “ST03” of the process C, the display unit 33 of the information display terminal device 30 displays the work instruction content “power supply installation work”, the power supply image, and the like. Installation is carried out as written, and the assembled personal computer is passed to the next inspection process.

  The host server device 20 recognizes that this process has been completed by another means, and an image for the inspection process (an image corresponding to the state “ST04”) and a non-defective notification image (an image corresponding to the state “ST05”) And the image for defect notification (image corresponding to the state “ST09”) is transmitted to the information display terminal device 30 via the display server device 10. The information display terminal device 30 receives an image group corresponding to the state group (state “ST04”, state “ST05”, state “ST09”) from the display server device 10 and displays an image corresponding to the state “ST04”. .

  In the inspection process state “ST04”, the display unit 33 of the information display terminal device 30 displays inspection items, personal computer images, and the like as work instruction contents, and the operator instructs the information display terminal device 30. Inspect as written. Based on the inspection result, the operator selects the next process. If it is a non-defective product, it is confirmed with an image corresponding to the state “ST05”, and if it is a defective product, it is confirmed with an image corresponding to the state “ST09”.

  The host server device 20 grasps the product status from the received information, and transmits an image for the next state transition to the information display terminal device 30 via the display server device 10.

  If the product is non-defective, the information display terminal device 30 automatically transitions to the state “ST06”, and the information display terminal device 30 acquires the image group corresponding to the state group (state “ST06” and state “ST07”) from the display server device 10. The image corresponding to “ST06” is displayed. The state “ST06” (shipping) is a step for preparing to ship a finished product, and the state “ST07 (packaging notification) is a step for notifying that the packaging of the finished product has been completed.

  When packing is completed and the image corresponding to the state “ST07” is confirmed, the state automatically changes to the standby state “ST08”. In the standby state, the screen returns to the initial screen.

  If it is defective, the information display terminal device 30 automatically transitions to the state “ST10”, and the information display terminal device 30 displays an image group corresponding to the state group (state “ST10”, state “ST11” state “ST12”) from the display server device 10. Acquire and display an image corresponding to the state “ST10”. The state “ST10” (correction) is a process for recovering a defective product, and the state “ST11” (correction notification) is a process for notifying that a defective product has been recovered, and the state “ST12” (analysis notification). Is a process of notifying that analysis is performed when a defective product cannot be recovered.

  The operator performs recovery according to the instructions on the information display terminal device 30. Based on the recovery result, the operator selects the next step. If it can be recovered, it is confirmed with the image corresponding to the state “ST11”.
