[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present disclosure will be described with reference to the accompanying drawings. In the drawings, the same or corresponding parts are designated by the same reference numerals, and redundant explanations will be appropriately simplified or omitted.

[0010] Embodiment 1 FIG. 1 is a configuration diagram of an equipment system having an equipment data acquisition system 100. The facility system in FIG. 1 is mainly composed of a facility data acquisition system 100, three facilities A, B, and C, a communication terminal 300, and a communication network 400.

[0011] 1, the equipment data acquisition system 100 includes a receiving device 101, a data processing device 102, an equipment information storage device 103, a stored data management device 104, and a data lake 105. The data processing device 102 also includes a data analysis unit 102a and a data acquisition instruction unit 102b. The data lake is a storage area that aggregates a huge amount of data from various sources and stores the data in its raw state. The equipment data acquisition system 100 is installed in a monitoring center, a data center, or the like.

[0012] The receiving device 101 is capable of wireless or wired communication with the alarm transmitting device 201A of facility A, the alarm transmitting device 201B of facility B, and the alarm transmitting device 201C of facility C via the communication network 400. The data processing device 102 is also capable of wireless or wired communication with the control device 202A of facility A and the control device 202B of facility B via the communication network 400. Note that facility C does not have a control device, or even if it does have a control device, communication is not possible because the communication protocols used are different or the information obtained through communication cannot be deciphered. Facilities A, B, and C here can be various things such as elevators, escalators, production facilities (machines), air conditioning facilities, and lighting facilities, but the following example will be mainly described assuming an elevator.

[0013] The data processing device 102 is also capable of wireless communication with a communication terminal 300 carried by a maintenance worker.

[0014] Next, the operation of each component in the block diagram of FIG. 1 will be described with reference to a flowchart. 2 is a flowchart showing the operation of the alarm issuing device 201. Note that the alarm issuing device 201 is a general term for the alarm issuing device 201A, the alarm issuing device 201B, and the alarm issuing device 201C, which perform the same operation.

[0015] The alarm issuing device 201 monitors whether an abnormality has occurred in the equipment, determines whether an abnormality has been detected (step S100), and if an abnormality is detected, transmits alarm data (step S101). For example, this alarm data includes the equipment name, alarm time, alarm content, and urgency. If equipment A is an elevator, the equipment name = A, alarm time = 09:00, alarm content = door open running, urgency = emergency, etc. Equipment names are assigned individually so that they are not duplicated among all the equipment targeted by the equipment data acquisition system 100.

[0016] 3 is a flowchart showing the notification data reception process in the equipment data acquisition system 100. First, the receiving device 101 determines whether notification data is included in the various data it receives, that is, whether notification data has been received (step S200). If the notification data has been received, the receiving device 101 assigns a reception time to the notification data and transfers it to the data processing device 102 (step S201).

[0017] In the data processing device 102, the data analysis unit 102a determines whether the equipment with the equipment name in the alert data has a control device 202 (step S202). FIG. 4 shows a registered equipment table 103a registered in the equipment information storage device 103. In this registered equipment table 103a, the equipment name 103a1, the communication address 103a2 of the alert issuing device 201 in that equipment, and the communication address 103a3 of the control device 202 are registered in tabular form. Therefore, the data analysis unit 102a reads the registered equipment table 103a and determines whether or not a control device is present based on whether or not the communication address 103a3 of the control device 202 corresponding to the equipment name in the alert data exists. For example, if the equipment name is A, the control device communication address aaa.aaa.aaa.2 exists, so it is determined that a control device is present. On the other hand, if the equipment name is C, the control device communication address does not exist, so it is determined that a control device is not present.

[0018] If the data analysis unit 102a determines in step S202 that a control device is present, it issues an inspection instruction to the data acquisition instruction unit 102b by adding the control device communication address 103a3 to the data acquisition instruction unit 102b (step S203), and transfers the alert data to the stored data management device 104 (step S204). The stored data management device 104 temporarily stores the alert data (step S205).

[0019] If the data analysis unit 102a determines in step S202 that there is no control device, it selects a maintenance person and requests the maintenance person to dispatch the person by specifying the equipment name to the communication terminal 300 that the maintenance person has (step S206).

[0020] Then, the alert data is transferred to the stored data management device 104 together with the dispatch request data (step S207). The stored data management device 104 adds the content of the dispatch request data to the content of the alert data, adds metadata, and stores the data in the data lake 105 (step S208). The dispatch request data may include, for example, the name of the maintenance worker who made the dispatch request, and the time of notification = 09:12.

[0021] Next, an explanation will be given of the inspection of each facility by the control device 202. Fig. 5 is a flowchart showing the inspection instruction process in the facility data acquisition system 100. Fig. 6 is a flowchart showing the inspection instruction process in the control device 202.

[0022] First, inspections include periodic inspections that are carried out periodically and emergency inspections that are carried out based on inspection instructions given in step S203 of the flowchart in FIG.

[0023] 5, the data acquisition instruction unit 102b determines whether the fixed time has arrived (step S300). The fixed time is the time when an inspection instruction is issued to the control device 202, and is set in advance as a time or a time interval. Note that this fixed time may be set to be the same for all connected control devices 202, or may be set to be different.

[0024] If it is not the scheduled time in step S300, it is determined whether or not an inspection instruction has been issued from the data analysis unit 102a (step S301). This inspection instruction is based on step S203 in the flowchart of FIG. 3, and is issued when alarm data has been received.

[0025] If it is determined in step S301 that an inspection instruction is present, an emergency inspection instruction is sent to the relevant control device 202, i.e., the control device 202 corresponding to the equipment name in the alert data (step S302). For example, if the equipment name in the alert data is A, an emergency inspection instruction is sent to the control device 202A with the control device communication address aaa.aaa.aaa.2 in the registered equipment table 103a.

[0026] Thereafter, it is determined whether inspection result data has been received from the control device 202 (step S303), and this is repeated until it is received.

[0027] As shown in the flowchart of FIG. 6, the control device 202 of each facility first determines whether a regular inspection instruction has been received (step S400), and if not, determines whether an emergency inspection instruction has been received (step S401). If it is determined in step S401 that an emergency inspection instruction has been received, the control device 202 inspects the facility and generates inspection result data (step S402). This inspection method is predetermined and differs for each facility. Possible inspection methods include checking the layout of the facility's component devices, test operations, and electrical system current inspection. Furthermore, for example, if facility A is an elevator, the inspection result data may include facility name = A, inspection time = 09:03, and acceleration = 1 m / s 2 , opening and closing of a door = open, etc.

[0028] The control device 202 determines whether or not a serious fault has occurred during the inspection in step S402 (step S403). This serious fault is one that requires repair by a maintenance technician and is set in advance.

[0029] If the control device 202 determines in step S403 that a serious failure has occurred, it adds a maintenance technician request flag to the inspection result data (step S404) and transmits the inspection result data to the data acquisition instruction unit 102b (step S405). If the control device 202 determines in step S403 that no serious failure has occurred, it transmits the inspection result data acquired in step S402 to the data acquisition instruction unit 102b in step S405. Thereafter, the control device 202 restarts the equipment (step S406). This is performed by incorporating a post-inspection restart instruction into the emergency inspection instruction.

[0030] In response to step S405 in Fig. 6, the inspection result data is received in step S303 in the flowchart of Fig. 5. The data acquisition instruction unit 102b passes the inspection result data to the data analysis unit 102a, and determines whether a maintenance person request flag has been added to the inspection result data (step S304). If it is determined in step S304 that a maintenance person request flag has not been added, the data analysis unit 102a transfers the inspection result data to the stored data management device 104 (step S305).

[0031] The stored data management device 104 adds the contents of the received inspection result data to the contents of the alarm data temporarily stored in step S205 of FIG. 3, adds metadata, and stores the data in the data lake 105 (step S306).

[0032] Furthermore, if it is determined in step S304 that a maintenance worker request flag has been added to the inspection result data, a maintenance worker is selected, and the equipment name is specified on the communication terminal 300 held by the maintenance worker to request dispatch (step S307).

[0033] Then, the inspection result data is transferred to the stored data management device 104 together with the dispatch request data (step S308). The stored data management device 104 adds the contents of the dispatch request data and the inspection result data to the contents of the alert data temporarily stored in step S205 of Fig. 3, adds metadata, and stores the data in the data lake 105 (step S309).

[0034] FIG. 7 shows the data stored in the data lake 105. Data group 105a is a case where an alert was issued in facility A equipped with control device 202A. The content of the alert data is facility name = A, alert time = 09:00, alert content = door open running, urgency = emergency, reception time when receiving device 101 received the alert data = 09:01, and the content of the inspection result data is inspection time = 09:03, acceleration = 1 m / s 2 , door opening and closing = open, is included.

[0035] Data group 105b is a case where an alert was issued in facility C, which is not equipped with a control device. The alert data includes the following contents: facility name = C, alert time = 09:10, alert content = running with door open, urgency = emergency, reception time when receiving device 101 received the alert data = 09:11, and the dispatch request data includes the maintenance worker who notified the dispatch request = XXX and the time of notification = 09:12.

[0036] 5, if the scheduled time has come, a regular inspection instruction is sent to the corresponding control device 202 (step S310). Thereafter, it is determined whether inspection result data has been received from the control device 202 (step S311), and this is repeated until it is received.

[0037] Since the control device 202 of each facility determines that it has received a periodic inspection instruction in step S400 of Fig. 6, the control device 202 inspects the facility and acquires inspection result data (step S407).Then, the control device 202 transmits the inspection result data as is to the data acquisition instruction unit 102b (step S408).

[0038] 6, the inspection result data is received in step S311 in the flowchart of FIG. 5, so the data acquisition instruction unit 102b transfers the inspection result data to the stored data management device 104 via the data analysis unit 102a (step S312). The stored data management device 104 adds metadata to the contents of the received inspection result data and stores it in the data lake 105 (step S313).

[0039] Data from various types of equipment is stored in a mixed manner in the data lake 105. In order to check the failure status at a later date, it is conceivable to extract and process data using the equipment name as a key.

[0040] In this way, in the first embodiment, when an abnormality occurs, the system responds to equipment alert data, instructs an inspection, and acquires and stores the inspection result data, making it easier to analyze the abnormality and investigate its cause.

[0041] In addition, by adding the contents of inspection result data from a nearby time to the contents of the alarm data and storing them, extraction and processing become easier.

[0042] In addition, for equipment with a control device, the contents of the inspection result data are added to the contents of the alarm data, and for equipment without a control device, the contents of the dispatch request data are added to the contents of the alarm data, making management easier by using a similar data format whether the equipment has a control device or not.

[0043] Furthermore, by conducting emergency inspections based on the receipt of alarm data and restarting the equipment after the inspection, it is expected that abnormalities can be resolved to some extent.

[0044] Although the alarm issuing device 201A of facility A equipped with the control device 202A and the alarm issuing device 201C of facility C equipped with no control device have the same configuration, they may be slightly modified. For example, the alarm issuing device 201C may be configured to eliminate the I / F function added for communication with the control device, or to eliminate the control communication program for the control device.

[0045] Furthermore, for equipment that does not have a control device, in addition to adding the contents of the dispatch request data to the contents of the alert data, the inspection status and repair status of equipment C by the maintenance personnel may be added, as shown in data group 105b in Fig. 7. In this case, the maintenance personnel will manually input the repair data from the communication terminal 300 and transmit it to the data analysis unit 102a.

[0046] Furthermore, if the facility is an elevator, possible alarm contents of the alarm data include improper landing and being trapped in addition to running with the door open.

[0047] 8 is a diagram showing an example of hardware resources of the data processing device 102. The data processing device 102 includes, as hardware resources, a processor 1021, a memory 1022, and a transmission / reception circuit 1023. Note that there may be a plurality of processors 1021, memories 1022, and transmission / reception circuits 1023.

[0048] The memory 1022 stores a program, which is read out as needed and executed by the processor 1021. A transmission / reception circuit 1023 is responsible for transmitting and receiving data to and from the control device 202 and the communication terminal 300.

[0049] The processor 1021 is also called a CPU (Central Processing Unit), central processing unit, arithmetic unit, microprocessor, microcomputer, or DSP. The memory 1022 may be a semiconductor memory, a magnetic disk, a flexible disk, an optical disk, a compact disk, a minidisk, or a DVD. Usable semiconductor memory includes RAM, ROM, flash memory, EPROM, EEPROM, etc.

[0050] 9 is a diagram showing another example of hardware resources of the data processing device 102. In the example of FIG. 9, the data processing device 102 includes a processing circuit including a processor 1021, a memory 1022, a transmission / reception circuit 1023, and dedicated hardware 1024. Some of the functions of the data processing device 102 are realized by the dedicated hardware 1024. Note that all of the functions of the data processing device 102 may be realized by the dedicated hardware 1024. The dedicated hardware 1024 may be a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof.

[0051] The hardware resources of the receiving device 101 and the stored data management device 104 are also the same as those shown in FIGS.

[0052] Embodiment 2 In the first embodiment, when the alarm data is received, it is determined whether or not the equipment has a control device based on the registered equipment table 103a in step S202 of Fig. 3. In contrast to this, in the second embodiment, when the alarm issuing device 201 generates the alarm data, it checks whether or not it has a corresponding control device 202, and if so, it inserts its communication address into the alarm data.

[0053] Figure 10 is a flowchart showing the report data reception process in the equipment data acquisition system 100 in embodiment 2. In this case, in step S210 of Figure 10, depending on whether the report data contains information about the control device, the flow branches to step S203 or step S206. This makes it possible to reduce the number of equipment information storage devices 103 and configure the equipment data acquisition system 100 more inexpensively.

[0054] Embodiment 3 After restarting the equipment in step S406 in FIG. 6, the possibility that the same abnormality occurs again within a short period of time is taken into consideration, and an inspection instruction is not issued in this case.

[0055] Fig. 11 is a flowchart showing the alarm data reception process in the equipment data acquisition system 100 in the third embodiment. In this case, after determining that a control device is present in step S202 of Fig. 11, it is determined whether the same alarm data has been present recently (step S211), and if not, the process proceeds to step S203, and if present, the process proceeds to step S206.

[0056] In this way, if an abnormality occurs even after restarting the equipment, maintenance personnel can be dispatched to quickly deal with the abnormality.

[0057] In this case, if the stored data management device 104 stores the contents of the current alert data in addition to the data group based on the previously stored alert data, it will be easier to analyze the abnormality and investigate its cause later.

[0058] Although the preferred embodiments have been described in detail above, the present invention is not limited to these embodiments, and various modifications and substitutions can be made to the above-described embodiments without departing from the scope of the disclosure.

[0059] Furthermore, when the number, quantity, amount, range, etc. of each element is mentioned in the embodiments, the device of this disclosure is not limited to the mentioned number unless otherwise specified or clearly specified in principle. Furthermore, the structures, etc. described in the embodiments are not necessarily essential unless otherwise specified or clearly specified in principle.
