Description

Technical Field

[0001] The present invention relates to a management support system for supporting the management of management objects.

Background Art

[0002] Conventionally, a hazardous material management system for managing hazardous materials, which is an example of management objects, is known (for example, see Patent Document 1). Such a hazardous material management system includes a database server and a client terminal connected to the database server via a LAN (Local Area Network). The database server has a storage means and an arithmetic unit, etc. The storage means includes a product master and inventory data, etc.

[0003] The product master stores the type, name, capacity of the container for use, and specified quantity of the hazardous materials to be handled. The inventory data stores the type, name, and quantity of the hazardous materials stored in the storage warehouse. The arithmetic unit combines the "quantity of hazardous material type" item in the inventory data with the "hazardous material type" item in the product master. The arithmetic unit calculates the total of the individual quantities in the storage warehouse and calculates a multiple of the specified quantity by performing an operation on the "quantity" item in the inventory data and the "capacity" item in the product master.

[0004] The hazardous material management system performs inventory management of the hazardous materials stored in the storage warehouse based on the calculation result by the arithmetic unit as described above. The calculation result by the arithmetic unit in the database server can be displayed on the client terminal.

Summary of the Invention

Problems to be Solved by the Invention

[0006] Incidentally, the doors to storage facilities where the aforementioned hazardous materials are kept are usually locked. These keys are often kept in a guard room far away from the storage facility. Therefore, users need to go to the guard room to get the key when entering the storage facility. Furthermore, when leaving the storage facility, users need to lock the door and then return the key to the guard room.

[0007] Furthermore, key removal information is generally managed by security guards recording it on paper. Therefore, when discrepancies are found in hazardous materials inventory data, the process of comparing key removal information with hazardous materials inventory data becomes cumbersome. Consequently, a management support system that facilitates the matching of managed data is desired. [Means for solving the problem]

[0008] The following describes various types of management support systems designed to address the above-mentioned challenges. [Aspect 1] A management support system comprising: a server having a memory unit; a user terminal configured to output an unlocking signal for unlocking an electronic lock provided on the door of the entrance to a storage room where managed objects are stored, and to transmit unlocking information including the user's ID and the date and time of unlocking to the server; and an information acquisition and transmission unit configured to acquire and transmit to the server the name, quantity, and date and time of removal of the managed objects being taken out of the storage room, as well as the unlocking information, wherein the server is configured to store the received unlocking information and the removal information received after the unlocking information in the memory unit.

[0009] With the above configuration, the server links the removal information and unlocking information and stores them in the memory unit, allowing for centralized management of the unlocking status of the electronic lock on the door of the storage room where the managed items are stored, and the inventory status of the managed items. Therefore, for example, if an inconsistency occurs between multiple data sets being managed, the data can be easily reconciled.

[0010] [Aspect 2] The management support system according to [Aspect 1], wherein the managed object is stored in a container and is taken out of the storage room in the container unit, and the information acquisition and transmission unit acquires the take-out information by reading a two-dimensional code attached to the managed object that contains the take-out information of the managed object.

[0011] With the above configuration, information on the removal of managed objects can be easily obtained simply by reading the two-dimensional code with the information acquisition and transmission unit. [Aspect 3] The management support system according to [Aspect 1], wherein the managed object is stored in a container and a required amount is taken out of the container and taken out of the storage room, and the information acquisition and transmission unit acquires the take-out information by reading the numerical value displayed on the weighing device when the managed object to be taken out of the storage room is weighed by the weighing device.

[0012] With the above configuration, information on the removal of managed objects can be easily obtained simply by reading the numerical value displayed on the weighing scale using the information acquisition and transmission unit. [Aspect 4] The management support system according to [Aspect 3], characterized in that the storage unit is configured to store, as the removal information, a pre-remaining amount which is the remaining amount of the managed object before the managed object is removed from the container, and a post-remaining amount which is the remaining amount of the managed object after the managed object is removed from the container, and the server includes a deviation signal output unit which outputs a deviation signal when the deviation between the pre-remaining amount in the latest removal information and the post-remaining amount in the removal information stored immediately before the removal information is greater than or equal to a preset value.

[0013] With the above configuration, for example, if the managed object is taken out illegally, a deviation signal is output from the deviation signal output unit, so that, for example, it is possible to notify that the managed object has been taken out illegally.

[0014] [Aspect 5] The management support system according to any one of [Aspect 1] to [Aspect 4], characterized in that the user terminal measures the elapsed time since the electronic lock was unlocked and issues a warning when the elapsed time reaches a preset time while the electronic lock is unlocked.

[0015] According to the above configuration, for example, if a user forgets to lock the electronic lock, the user will be able to realize that they have forgotten to lock it. [Aspect 6] The management support system according to any one of [Aspect 1] to [Aspect 5], wherein the managed objects include hazardous materials, the storage unit is configured to store the total quantity of hazardous materials stored in the storage room and a designated quantity of hazardous materials, and the server receives storage information, including the quantity of hazardous materials stored, transmitted from the user terminal when hazardous materials are stored in the storage room, and transmits warning information to the user terminal if the total quantity of hazardous materials, including the quantity of hazardous materials stored, is equal to or greater than the designated quantity of hazardous materials, and the user terminal issues a warning when it receives the warning information.

[0016] According to the above configuration, it is possible to prevent the total quantity of hazardous materials stored in the storage room from exceeding the designated quantity of hazardous materials. [Effects of the Invention]

Mode for Carrying Out the Invention

[0019] Hereinafter, an embodiment will be described with reference to the drawings. <Storage Room 12> FIG. 1 shows a storage room 12 to which the management support system 11 is applied. The storage room 12 may be inside a warehouse or may be one room of a building having a plurality of rooms. An electronic lock 14 for locking the door 13 is provided on the door 13 at the entrance of the storage room 12. Inside the storage room 12, dangerous goods 15 as an example of the management object and highly toxic substances 16 as an example of the management object are stored in a state of being placed on a plurality of tiers of the first shelf 17 and a plurality of tiers of the second shelf 18, respectively.

[0020] <Dangerous Goods 15> As shown in FIG. 1, a plurality of types of dangerous goods 15 are placed on the first shelf 17. The dangerous goods 15 are, for example, flammable liquids classified into Class 4 such as oil-based paint. The dangerous goods 15 are stored in the storage room 12 in a state of being contained in a container such as a can, and are carried out of the storage room 12 in units of containers. A card 19 shown in FIG. 2 is attached to the container containing the dangerous goods 15. The card 19 is printed with a two-dimensional code 20 and various information including the name and quantity (volume) of the dangerous goods 15 contained in the container to which the card 19 is attached. The card 19 may be attached to the container containing the corresponding dangerous goods 15.

[0021] <Highly Toxic Substances 16> As shown in Figure 1, the second shelf 18 contains several types of poisonous and deleterious substances 16. Poisonous and deleterious substances 16 refer to poisons and deleterious substances. Poisons are more toxic than deleterious substances. The poisonous and deleterious substances 16 are stored in the storage room 12 in containers such as bottles, and the necessary amount is taken out of the container and taken out of the storage room 12. The amount of poisonous and deleterious substances 16 taken out of the storage room 12 must be weighed and managed.

[0022] When the poisonous and hazardous substance 16 is taken outside the storage room 12, the amount of poisonous and hazardous substance 16 remaining before it is removed from the container (pre-remaining amount / weight) and the amount of poisonous and hazardous substance 16 remaining after it is removed from the container (post-remaining amount / weight) are weighed and managed. For this reason, an electronic scale 21, as an example of a weighing device for weighing the poisonous and hazardous substance 16 as shown in Figure 3, is kept on the second shelf 18 of the storage room 12.

[0023] The electronic scale 21 has a placement section 22 on which the poisonous and hazardous substance 16 is placed when it is weighed by the electronic scale 21 before being taken out of the storage room 12, and a display section 23 that digitally displays the weighing result of the poisonous and hazardous substance 16 placed on the placement section 22 as a numerical value.

[0024] <Electronic Lock 14> As shown in Figures 1 and 4, the electronic lock 14 is composed of, for example, an electronic padlock. The electronic lock 14 includes a lock communication unit 24, a lock control unit 25, a drive circuit 26, and a drive motor 27. The lock communication unit 24 receives an unlocking signal transmitted (output) from a user terminal 28, which will be described later. The communication standard at this time is, for example, Bluetooth®, Wi-Fi®, and ZigBee®.

[0025] When the lock control unit 25 receives an unlocking signal from the lock communication unit 24, it transmits a drive signal to the drive circuit 26. When the drive circuit 26 receives the drive signal transmitted from the lock control unit 25, it supplies a drive current to the drive motor 27. As a result, the drive motor 27 is driven and the electronic lock 14 is unlocked.

[0026] <Management Support System 11> As shown in Figures 1, 5, and 6, the management support system 11 comprises a server 29 and a user terminal 28. The server 29 and the user terminal 28 are connected via a network such as the Internet or an intranet.

[0027] <User Terminal 28> As shown in Figures 1 and 5, the user terminal 28 is comprised of, for example, a smartphone or a tablet device. The user terminal 28 includes a terminal communication unit 30, a display operation unit 31, a terminal storage unit 32, a camera 33, an unlock signal output unit 34, and a terminal control unit 35. The terminal communication unit 30 is configured to enable wireless communication with the server communication unit 36 ​​(see Figure 6) of the server 29. As a result, the terminal communication unit 30 communicates data with the server 29.

[0028] The display operation unit 31 is configured, for example, as a touch panel. Various input operations are performed on the display operation unit 31 by the user 37. The terminal storage unit 32 is configured as ROM (Read Only Memory) and RAM (Random Access Memory), etc. The terminal storage unit 32 stores various programs, a pre-set time T (described later), and the ID of the user 37 who is registered as the user of the user terminal 28. The terminal storage unit 32 temporarily stores the contents of the communication between the user terminal 28 and the server 29.

[0029] Camera 33 captures images of the two-dimensional code 20 printed on the card 19 shown in Figure 2, or the weighing result of the poisonous substance 16, which is digitally displayed numerically on the display unit 23 of the electronic scale 21 shown in Figure 3. The image data captured by camera 33 is stored in the terminal storage unit 32. In this case, the image data captured by camera 33 includes date and time information of when the image data was captured.

[0030] The unlock signal output unit 34 transmits (outputs) an unlock signal to unlock the electronic lock 14 shown in Figures 1 and 4 when the user 37 selects, for example, the "unlock" icon shown in Figure 7, which is displayed on the display operation unit 31 using an application on the user terminal 28.

[0031] The terminal control unit 35 constructs an information acquisition unit 38, an information transmission unit 39, and a warning unit 40 by executing a control program stored in the terminal storage unit 32. The information acquisition unit 38 acquires information including the name, quantity (volume), and date and time of removal of hazardous materials 15 being taken out of the storage room 12 by reading image data of a two-dimensional code 20 (see Figure 2) captured by the camera 33.

[0032] The information acquisition unit 38 acquires information about the removal of poisonous and hazardous substances 16, including the quantity (weight) and the date and time of removal, by reading the numerical image data displayed on the display unit 23 of the electronic scale 21, which has been captured by the camera 33, using image recognition. When the name of the poisonous and hazardous substance 16 to be taken out of the storage room 12 is entered by the user 37 from the display operation unit 31, the information acquisition unit 38 acquires the name of the poisonous and hazardous substance 16 as removal information. When an unlocking signal to unlock the electronic lock 14 is transmitted from the unlocking signal output unit 34, the information acquisition unit 38 acquires unlocking information including the user 37's ID and the date and time of unlocking.

[0033] The information transmission unit 39 transmits the removal information and unlocking information acquired by the information acquisition unit 38 to the server 29. In this case, the information transmission unit 39 transmits the removal information and unlocking information acquired by the information acquisition unit 38 to the server 29 in real time, so it transmits the removal information to the server 29 after the unlocking information. In this embodiment, the information acquisition and transmission unit is configured by the user terminal 28.

[0034] The warning unit 40 measures the elapsed time since the electronic lock 14 was unlocked, that is, the elapsed time since the unlock signal output unit 34 transmitted the unlock signal. When the elapsed time since the electronic lock 14 was unlocked reaches a set time T, the warning unit 40 issues an audible warning, for example, by displaying a warning on the display operation unit 31. When the terminal communication unit 30 receives a deviation signal, which will be described later, the warning unit 40 issues an audible warning, for example, by displaying a warning on the display operation unit 31.

[0035] The warning unit 40 stops measuring the elapsed time since the unlock signal was sent by the unlock signal output unit 34 when the user 37 selects, for example, the "lock" icon shown in Figure 7, which is displayed on the display operation unit 31 in the application on the user terminal 28.

[0036] <Server 29> As shown in Figure 6, the server 29 may be configured, for example, as a cloud server operating in a cloud computing environment, or as one or more general-purpose computers such as workstations or personal computers. The server 29 includes a server communication unit 36, a server storage unit 41 as an example of a storage unit, and a server control unit 42.

[0037] As shown in Figures 5 and 6, the server communication unit 36 ​​is configured to enable wireless communication with the terminal communication unit 30 of the user terminal 28. This allows the server communication unit 36 ​​to communicate data with the user terminal 28. The server storage unit 41 is composed of ROM, RAM, and the like. Various programs and pre-set configuration values ​​S (described later) are stored in the server storage unit 41.

[0038] The server storage unit 41 stores various information and data transmitted from the user terminal 28. In this case, the server storage unit 41 stores unlocking information received by the server communication unit 36 ​​and take-out information received by the server communication unit 36 ​​after the unlocking information, linked together, as shown in Figure 8, for example.

[0039] The server storage unit 41 is configured to store, each time the poisonous substance 16 is taken out of the storage room 12, the pre-remaining amount (weight), which is the amount of poisonous substance 16 remaining before it is removed from the container, and the post-remaining amount (weight), which is the amount of poisonous substance 16 remaining after it is removed from the container, which are transmitted from the user terminal 28.

[0040] The server control unit 42 constructs a divergence signal output unit 43 by executing a control program stored in the server storage unit 41. The divergence signal output unit 43 transmits (outputs) a divergence signal to, for example, the user terminal 28 if the divergence between the remaining amount before the most recent withdrawal information and the remaining amount after the withdrawal information stored in the server storage unit 41 immediately before the withdrawal information is greater than or equal to a preset value S. The preset value S is set to, for example, a value that allows for a divergence between the remaining amount before and after the withdrawal due to measurement error.

[0041] <Operation of the Embodiment> Next, we will explain the process when user 37 takes hazardous material 15 out of storage room 12. As shown in Figure 1, when user 37 takes hazardous materials 15 from storage room 12, first, user 37 performs an operation in front of the electronic lock 14 by selecting the "unlock" icon, for example, shown in Figure 7, displayed on the display operation unit 31 using an application on user terminal 28. Then, an unlock signal is sent from user terminal 28 to the electronic lock 14, and the electronic lock 14 is unlocked. At this time, unlock information is sent from user terminal 28 to server 29, and this unlock information is stored in server 29.

[0042] Next, user 37 opens door 13 and enters storage room 12. Then, user 37 takes out the container containing the hazardous material 15 along with the attached card 19 from shelf 17. Next, user 37 uses the camera 33 of user terminal 28 to scan the two-dimensional code 20 on card 19. As a result, information about the removal of the hazardous material 15 is transmitted from user terminal 28 to server 29, and this removal information is stored in server 29. At this time, server 29 stores the unlocking information and the removal information linked together, for example, as shown in Figure 8.

[0043] Next, user 37 takes the container containing the hazardous material 15 along with the attached card 19 out of the storage room 12, for example, using a trolley. Then, user 37 manually locks the electronic lock 14 with the door 13 closed. Next, user 37 performs an operation on the application on the user terminal 28 to select the "lock" icon, for example, shown in Figure 7, displayed on the display operation unit 31.

[0044] Furthermore, if user 37 forgets to lock the electronic lock 14, the user terminal 28 will, for example, display a warning on the display operation unit 31 and issue an audible warning when the elapsed time since the electronic lock 14 was unlocked reaches a set time T. This allows user 37 to realize that they have forgotten to lock the electronic lock 14.

[0045] Next, we will explain the process by which user 37 takes the poisonous substance 16 from storage room 12. As shown in Figure 1, when user 37 takes poisonous or hazardous material 16 from storage room 12, first, user 37 performs an operation in front of the electronic lock 14 by selecting the "unlock" icon, for example, shown in Figure 7, displayed on the display operation unit 31 using an application on user terminal 28. Then, an unlock signal is sent from user terminal 28 to the electronic lock 14, and the electronic lock 14 is unlocked. At this time, unlock information is sent from user terminal 28 to server 29, and this unlock information is stored in server 29.

[0046] Next, user 37 opens door 13 and enters storage room 12. Next, user 37 takes out a container containing poisonous / deleterious substance 16 from second shelf 18. Next, user 37 inputs the name of the poisonous / deleterious substance 16 taken out from second shelf 18 by operating the display operation unit 31 of user terminal 28. The name of the poisonous / deleterious substance 16 is then sent from user terminal 28 to server 29 as removal information, and this removal information is stored in server 29. At this time, server 29 stores the unlocking information and removal information linked together, for example, as shown in Figure 8.

[0047] Next, user 37 weighs the remaining amount of the poisonous substance 16 before it is removed from the container using the electronic scale 21. Then, user 37 takes an image of the remaining amount of the poisonous substance 16 displayed on the display unit 23 of the electronic scale 21 using the camera 33 of the user terminal 28.

[0048] Then, the user terminal 28 transmits the previous remaining amount of the poisonous substance 16 to the server 29, and this previous remaining amount is stored in the server 29. At this time, if the discrepancy between the previously measured amount of the poisonous substance 16 and the previously measured amount of the poisonous substance 16 is greater than or equal to a set value S, the user terminal 28 notifies the user 37 that the remaining amount of the poisonous substance 16 is inconsistent.

[0049] Next, user 37 takes out the required amount of poisonous / hazardous substance 16 from the container containing the poisonous / hazardous substance 16 and weighs it using the electronic scale 21. Then, user 37 uses the camera 33 of user terminal 28 to capture an image of the amount of poisonous / hazardous substance 16 taken out, which is displayed on the display unit 23 of the electronic scale 21. The amount of poisonous / hazardous substance 16 taken out, along with the date and time of removal, is then transmitted from user terminal 28 to server 29 as removal information, and this removal information is stored in server 29. At this time, server 29 stores the unlocking information and removal information linked together, for example, as shown in Figure 8.

[0050] Next, user 37 places the toxic substance 16 that has been removed from the container and weighed into a separate container for transport. Then, user 37 weighs the remaining amount of toxic substance 16 after it has been removed from the container using an electronic scale 21. Next, user 37 takes a picture of the remaining amount of toxic substance 16 displayed on the display unit 23 of the electronic scale 21 with the camera 33 of the user terminal 28. The remaining amount of toxic substance 16 is then transmitted from the user terminal 28 to the server 29, and the original amount is stored in the server 29.

[0051] Next, user 37 returns the container containing the poisonous substance 16 to its original position on the second shelf 18, and then takes the container containing the poisonous substance 16 out of the storage room 12. Next, user 37 manually locks the electronic lock 14 with the door 13 closed. Next, user 37 performs an operation on the application on the user terminal 28 to select the "lock" icon displayed on the display operation unit 31, for example, as shown in Figure 7.

[0052] Furthermore, if user 37 forgets to lock the electronic lock 14, the user terminal 28 will, for example, display a warning on the display operation unit 31 and issue an audible warning when the elapsed time since the electronic lock 14 was unlocked reaches a set time T. This allows user 37 to realize that they have forgotten to lock the electronic lock 14.

[0053] In this way, the management support system 11 assists in managing the unlocking status of the electronic lock 14 installed on the door 13 of the entrance to the storage room 12, and the inventory status of the hazardous materials 15 and poisonous and deleterious substances 16 stored in the storage room 12.

[0054] <Effects of the Embodiment> According to the embodiments described in detail above, the following effects are achieved. (1) The management support system 11 comprises a server 29 having a server storage unit 41, and a user terminal 28 configured to output an unlocking signal to unlock an electronic lock 14 provided on the door 13 of the entrance to the storage room 12 where the hazardous materials 15 and poisonous and deleterious substances 16 are stored, and to transmit unlocking information including the user 37's ID and the date and time of unlocking to the server 29, and to acquire and transmit to the server 29 the name, quantity and date and time of removal of the hazardous materials 15 and poisonous and deleterious substances 16 that are taken out of the storage room 12, along with the unlocking information. The server 29 is configured to store the received unlocking information and the removal information received after the unlocking information in the server storage unit 41.

[0055] According to the above configuration, the server 29 links the removal information and unlocking information and stores them in the server storage unit 41. Therefore, the unlocking status of the electronic lock 14 installed on the door 13 of the entrance to the storage room 12 where the hazardous materials 15 and poisonous and deleterious substances 16 are stored, and the inventory status of the hazardous materials 15 and poisonous and deleterious substances 16 can be centrally managed. Consequently, for example, if an inconsistency occurs between the managed removal information and unlocking information, the verification process between the removal information and unlocking information can be easily performed.

[0056] (2) In the management support system 11, the hazardous materials 15 are stored in containers and are taken out of the storage room 12 in container units. The user terminal 28 obtains the removal information by reading the two-dimensional code 20 attached to the hazardous materials 15, which contains the removal information of the hazardous materials 15.

[0057] According to the above configuration, information on the removal of hazardous materials 15 can be easily obtained simply by reading the two-dimensional code 20 with the user terminal 28. (3) In the management support system 11, the poisonous and deleterious substances 16 are stored in containers, and the required amount is taken out of the containers and taken out of the storage room 12. The user terminal 28 obtains the information about the removal of the poisonous and deleterious substances 16 that are taken out of the storage room 12 by reading the numerical value displayed on the display unit 23 of the electronic scale 21 when the poisonous and deleterious substances 16 are weighed by the electronic scale 21.

[0058] With the above configuration, information on the removal of poisonous and hazardous substances 16 can be easily obtained simply by reading the numerical value displayed on the display unit 23 of the electronic scale 21 using the user terminal 28. (4) In the management support system 11, the server storage unit 41 is configured to store, as removal information, the pre-remaining amount, which is the remaining amount of poisonous and hazardous substance 16 before it is removed from the container, and the post-remaining amount, which is the remaining amount of poisonous and hazardous substance 16 after it is removed from the container. The server 29 includes a deviation signal output unit 43 that transmits a deviation signal to the user terminal 28 when the deviation between the pre-remaining amount in the latest removal information and the post-remaining amount in the removal information stored immediately before the removal information is greater than or equal to a preset value S.

[0059] With the above configuration, for example, if the poisonous or hazardous substance 16 is taken out illegally, a deviation signal is sent from the deviation signal output unit 43 to the user terminal 28, so that the user 37 can be notified, for example, that the poisonous or hazardous substance 16 has been taken out illegally.

[0060] (5) In the management support system 11, the user terminal 28 measures the elapsed time since the electronic lock 14 was unlocked, and issues a warning when the elapsed time while the electronic lock 14 is unlocked reaches a preset time T.

[0061] According to the above configuration, for example, if user 37 forgets to lock the electronic lock 14, user 37 can become aware that they have forgotten to lock it. <Example of changes> The above embodiment can be implemented with the following modifications. Furthermore, the above embodiment and the following modifications can be combined with each other to the extent that they do not contradict each other technically.

[0062] The server storage unit 41 may be configured to store the total quantity of hazardous materials 15 stored in the storage room 12, as well as the designated quantity of hazardous materials 15. The designated quantity is the amount of hazardous materials 15 that can be stored as stipulated by the Fire Service Act. The following describes the process when a user 37 deposits hazardous materials 15 into the storage room 12.

[0063] When user 37 stores hazardous materials 15 in storage room 12, they input storage information, including the quantity of hazardous materials 15, from the display operation unit 31 using an application on user terminal 28. The storage information is then sent from user terminal 28 to server 29, where it is received. Subsequently, if the total quantity of hazardous materials 15, including the newly added quantity, exceeds the designated quantity for hazardous materials 15, server 29 sends a warning to user terminal 28.

[0064] Then, when the user terminal 28 receives warning information transmitted from the server 29, for example, the warning unit 40 displays the warning on the display operation unit 31 and issues an audible warning to that effect. As a result, the user 37 can realize that the entry of the hazardous material 15 into the storage room 12 will result in the total quantity of hazardous material 15 stored in the storage room 12 exceeding the designated quantity of hazardous material 15. Therefore, it is possible to prevent the total quantity of hazardous material 15 stored in the storage room 12 from exceeding the designated quantity of hazardous material 15.

[0065] The user terminal 28 does not necessarily need to measure the elapsed time since the electronic lock 14 was unlocked, or issue a warning when the elapsed time while the electronic lock 14 is unlocked reaches a preset time T.

[0066] The server 29 does not necessarily need to be equipped with a divergence signal output unit 43. The divergence signal output unit 43 may be configured to transmit (output) the divergence signal not only to the user terminal 28, but also to, for example, a master terminal connected to the server 29 in a communicative manner.
