Detailed Implementation

[0022] The embodiments for implementing this disclosure are described with reference to the accompanying drawings. Furthermore, in the drawings, identical or equivalent parts are labeled with the same reference numerals, and repeated descriptions are appropriately simplified or omitted.

[0023] Implementation Method 1

[0024] Figure 1 This is a structural diagram of a device system with a device data acquisition system 100.

[0025] Figure 1The equipment system mainly consists of equipment data acquisition system 100, three devices A, B, and C, communication terminal 300, and communication network 400.

[0026] exist Figure 1 The equipment data acquisition system 100 includes a receiving device 101, a data processing device 102, an equipment information storage device 103, a data storage and management device 104, and a data lake 105. Furthermore, the data processing device 102 includes a data analysis unit 102a and a data acquisition instruction unit 102b. Additionally, a data lake refers to a storage area that aggregates large amounts of data from various sources and stores the data in an unprocessed state. Moreover, the equipment data acquisition system 100 is installed in monitoring centers, data centers, etc.

[0027] The receiving device 101 can communicate wirelessly or wiredly with the transmitting device 201A of device A, the transmitting device 201B of device B, and the transmitting device 201C of device C via the communication network 400. Furthermore, the data processing device 102 can communicate wirelessly or wiredly with the control device 202A of device A and the control device 202B of device B via the communication network 400. Additionally, device C lacks a control device, or even if it has a control device, the communication protocols are different, or it cannot interpret the information obtained during communication, therefore it is assumed to be unable to communicate. Devices A, B, and C here correspond to various devices such as elevators, escalators, production equipment (machinery), air conditioning equipment, and lighting equipment; however, as an example below, an elevator will be primarily used for explanation.

[0028] The data processing device 102 can also communicate wirelessly with the communication terminal 300 held by the maintenance personnel.

[0029] Next, according to the flowchart... Figure 1 The actions of each structure in the block diagram are explained.

[0030] Figure 2 This is a flowchart illustrating the operation of the transmitting device 201. Furthermore, transmitting device 201 is a collective term for transmitting devices 201A, 201B, and 201C, all of which perform the same operations.

[0031] The transmitting device 201 monitors for any abnormalities occurring in the equipment and determines whether an abnormality has been detected (step S100). If an abnormality is detected, it sends transmitting data (step S101). Furthermore, for example, the transmitting data includes the equipment name, transmitting time, transmitting content, and urgency level. In the case that equipment A is an elevator, equipment name = A, transmitting time = 09:00, transmitting content = door open and moving, urgency level = emergency, etc. The equipment name is assigned individually in a way that it will not be repeated among all the equipment that is an object of the equipment data acquisition system 100.

[0032] Figure 3 This is a flowchart illustrating the data transmission and reception processing in the device data acquisition system 100. First, the receiving device 101 determines whether there is transmitted data among the various types of data to be received, that is, whether transmitted data has been received (step S200). If transmitted data has been received, the receiving device 101 assigns a reception time to the transmitted data and forwards it to the data processing device 102 (step S201).

[0033] In the data processing device 102, the data analysis unit 102a determines whether the device in the transmitted data has a control device 202 (step S202). Figure 4 This is the device registration table 103a registered in the device information storage device 103. In this device registration table 103a, the device name 103a1, the communication address 103a2 of the transmitting device 201 located in that device, and the communication address 103a3 of the control device 202 are registered in a table format. Therefore, the data analysis unit 102a reads the device registration table 103a and determines whether a control device exists based on whether there is a communication address 103a3 for the control device 202 corresponding to the device name in the transmitted data. For example, if the device name is A, and the control device communication address aaa.aaa.aaa.2 exists, then it is determined that a control device exists. Conversely, if the device name is C, and there is no control device communication address, then it is determined that no control device exists.

[0034] If the data analysis unit 102a determines in step S202 that a control device is present, it attaches the control device communication address 103a3 to the data acquisition instruction unit 102b and issues an inspection instruction (step S203), and forwards the transmission data to the data storage management device 104 (step S204). The data storage management device 104 temporarily stores the transmission data (step S205).

[0035] If the data analysis unit 102a determines in step S202 that there is no control device, it selects a maintenance worker, assigns a device name to the communication terminal 300 owned by the maintenance worker, and requests dispatch (step S206).

[0036] Then, the transmitted data and the dispatch request data are forwarded together to the data storage management device 104 (step S207). In the data storage management device 104, the content of the dispatch request data is appended to the content of the transmitted data, metadata is assigned, and it is stored in the data lake 105 (step S208). In addition, the dispatch request data may include, for example, the name of the maintenance personnel who made the dispatch request, the time of notification, etc.

[0037] Next, the inspection of the control device 202 of each device will be explained. Figure 5This is a flowchart illustrating the inspection instruction processing in the device data acquisition system 100. Figure 6 This is a flowchart illustrating the inspection instruction processing in the control device 202.

[0038] Firstly, regarding inspections, there are regular inspections conducted periodically and inspections based on... Figure 3 An emergency inspection is performed in accordance with the inspection instructions in step S203 of the flowchart.

[0039] exist Figure 5 In step S300, the data acquisition instruction unit 102b determines whether it is a specified time. The specified time is the time for the control device 202 to be inspected, and is preset in terms of a time interval or time period. In addition, the specified time can be set to be the same or different for all control devices 202 to be connected.

[0040] If the specified time is not in step S300, it is determined whether there is an inspection instruction from the data analysis unit 102a (step S301). This inspection instruction is based on... Figure 3 Step S203 in the flowchart represents the situation where the transmitted data has been received.

[0041] If an inspection instruction is determined to exist in step S301, an emergency inspection instruction is sent to the corresponding control device 202, i.e., the control device 202 corresponding to the device name that sent the data (step S302). For example, if the device name that sent the data is A, an emergency inspection instruction is sent to control device 202A with the control device communication address aaa.aaa.aaa.2 by registering the device table 103a.

[0042] Then, it is determined whether inspection result data has been received from the control device 202 (step S303), and the determination is repeated until inspection result data is received.

[0043] In the control device 202 of each device, such as Figure 6 As shown in the flowchart, firstly, it is determined whether a periodic inspection instruction has been received (step S400). If no periodic inspection instruction has been received, it is determined 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 performs an inspection of the equipment and generates inspection result data (step S402). This inspection method is predetermined and varies for each piece of equipment. It takes into account the configuration confirmation of the equipment's constituent machines, test operations, and power-on checks of the electrical system. Furthermore, as inspection result data, for example, in the case where equipment A is an elevator, the data would be: Equipment Name = A, Inspection Time = 09:03, Acceleration = 1 m / s². 2 The opening and closing of a door = opening, etc.

[0044] In step S402, the control device 202 determines whether a major fault exists during the inspection (step S403). This major fault requires repair by a maintenance personnel and is preset.

[0045] If the control device 202 determines that a major fault has occurred in step S403, it adds a maintenance personnel request flag to the inspection result data (step S404) and sends the inspection result data to the data acquisition instruction unit 102b (step S405). Furthermore, if it determines that no major fault has occurred in step S403, it sends the inspection result data acquired in step S402 to the data acquisition instruction unit 102b in step S405. Then, the control device 202 restarts the equipment (step S406). This is done by embedding a restart instruction after the inspection into the emergency inspection instruction.

[0046] go through Figure 6 Step S405, in Figure 5 In the flowchart, in step S303, the inspection result data is received. The data acquisition instruction unit 102b hands the inspection result data to the data analysis unit 102a, and determines whether a maintenance personnel request flag has been attached to the inspection result data (step S304). If it is determined in step S304 that no maintenance personnel request flag has been attached, the data analysis unit 102a forwards the inspection result data to the data storage management device 104 (step S305).

[0047] Data storage management device 104 pairs in Figure 3 In step S205, the content of the temporarily stored transmission data is appended with the content of the received inspection result data, metadata is assigned, and it is stored in data lake 105 (step S306).

[0048] Furthermore, if it is determined in step S304 that a maintenance worker request flag has been attached to the inspection result data, a maintenance worker is selected, the device name of the communication terminal 300 owned by the maintenance worker is specified, and a request is made to dispatch (step S307).

[0049] Then, the inspection result data and the dispatch request data are forwarded together to the data storage management device 104 (step S308). In the data storage management device 104, the data is processed... Figure 3 In step S205, the content of the dispatch request data and the inspection result data are added to the temporarily stored transmission data, metadata is assigned, and stored in data lake 105 (step S309).

[0050] Figure 7 It is the data stored in Data Lake 105.

[0051] Data group 105a refers to a situation where a message is transmitted from device A, which has control device 202A. The message includes the following: device name = A, transmission time = 09:00, transmission content = door open and move, urgency level = emergency, reception time of the transmitted data received by receiving device 101 = 09:01, inspection time as inspection result data = 09:03, acceleration = 1 m / s². 2 The opening and closing of a door = opening.

[0052] Data group 105b refers to a situation where a message is transmitted from device C, which does not have a control device. The message contains the following information: device name = C, transmission time = 09:10, transmission content = door opening and driving, urgency level = emergency, receiving time of receiving the message from receiving device 101 = 09:11, maintenance personnel who notified of the dispatch request as data = XXX, notification time = 09:12.

[0053] exist Figure 5 In step S300, when the specified time is reached, a periodic inspection instruction is sent to the corresponding control device 202 (step S310). Then, it is determined whether inspection result data has been received from the control device 202 (step S311), and the determination is repeated until inspection result data is received.

[0054] In the control device 202 of each device, Figure 6 In step S400, it is determined that a periodic inspection instruction has been received. Therefore, the control device 202 performs an inspection of the equipment and obtains the inspection result data (step S407). Then, the inspection result data is directly sent to the data acquisition instruction unit 102b (step S408).

[0055] go through Figure 6 Step S408, in Figure 5 In the flowchart, the inspection result data is received in step S311. Therefore, the data acquisition instruction unit 102b forwards the inspection result data to the data storage management device 104 via the data analysis unit 102a (step S312). The data storage management device 104 adds metadata to the content of the received inspection result data and stores it in the data lake 105 (step S313).

[0056] In addition, data from various devices is stored together in Data Lake 105. In the future, to confirm the fault status, we will consider using device names and other keywords to extract and process the data.

[0057] Thus, in Implementation 1, when an anomaly occurs, an inspection is instructed in accordance with the equipment's transmitted data, and the inspection result data is obtained and saved. Therefore, it is easy to analyze the anomaly and investigate the cause.

[0058] In addition, the content of the transmitted data is supplemented with the inspection results data of a similar time and stored, which makes it easy to extract and process.

[0059] Furthermore, in equipment with a control device, the content of the transmitted data is supplemented with the content of the inspection result data; in the absence of a control device, the content of the transmitted data is supplemented with the content of the dispatch request data. In this way, the data becomes the same in the case of having a control device and not having a control device, thereby facilitating management.

[0060] Furthermore, in emergency inspections based on received data, the equipment is restarted after the inspection, which can help eliminate the anomaly to some extent.

[0061] Furthermore, while the transmitting device 201A of device A, which has a control device 202A, and the transmitting device 201C of device C, which does not have a control device, can be configured with the same structure, slight modifications are also possible. For example, the transmitting device 201C can be configured to reduce the I / F function added for connecting to the control device, or to reduce the control communication program for the control device.

[0062] Furthermore, regarding equipment without control devices, such as Figure 7 As shown in data group 105b, in addition to attaching dispatch request data to the content of the transmitted data, information on the maintenance personnel's inspection and repair status of equipment C can also be added. In this case, the maintenance personnel manually input the repair data from the communication terminal 300 and send it to the data analysis unit 102a.

[0063] In addition, when the equipment is an elevator, the content of the data transmission should include not only door opening and movement, but also issues such as poor floor stopping and being trapped.

[0064] Figure 8 This diagram illustrates an example of the hardware resources of the data processing device 102. As hardware resources, the data processing device 102 includes a processor 1021, a memory 1022, and a transceiver circuit 1023. Alternatively, there may be multiple processors 1021, memory 1022, and transceiver circuits 1023.

[0065] The program is stored in the memory 1022, and is read out appropriately and executed by the processor 1021. In addition, the transceiver circuit 1023 is responsible for data transmission and reception with the control device 202 and the communication terminal 300.

[0066] Additionally, the processor 1021 is also referred to as a CPU (Central Processing Unit), central processing unit, arithmetic unit, microprocessor, microcomputer, or DSP. The memory 1022 can also be a semiconductor memory, magnetic disk, floppy disk, optical disk, high-density disk, mini-disk, or DVD. Suitable semiconductor memories include RAM, ROM, flash memory, EPROM, and EEPROM.

[0067] Figure 9 This is a diagram illustrating another example of the hardware resources of the data processing device 102. Figure 9 In the example, the data processing device 102 has processing circuitry including a processor 1021, a memory 1022, a transceiver circuitry 1023, and dedicated hardware 1024. Furthermore, a portion of the functions of the data processing device 102 are implemented by the dedicated hardware 1024. Alternatively, all the functions of the data processing device 102 can be implemented by the dedicated hardware 1024. The dedicated hardware 1024 can be a single circuit, a composite circuit, a programmable processor, a parallel programmable processor, an ASIC, an FPGA, or a combination thereof.

[0068] In addition, the hardware resources of the receiving device 101 and the data storage and management device 104 are also related to... Figure 8 , Figure 9 The situation is the same as shown.

[0069] Implementation Method 2

[0070] In implementation method 1, upon receiving the transmitted data, in Figure 3 In step S202, it is determined whether the device has a control device according to the device registration table 103a. In contrast, in embodiment 2, when the transmitting device 201 generates transmitting data, it is determined whether there is a corresponding control device 202. If there is a control device 202, its communication address is included in the transmitting data.

[0071] Figure 10 This is a flowchart illustrating the data transmission and reception processing in the device data acquisition system 100 of Embodiment 2. Furthermore, in this case, Figure 10 In step S210, depending on whether there is information related to the control device in the transmitted data, the process is divided into a process leading to step S203 and a process leading to step S206. Therefore, the device information storage device 103 can be reduced, and the device data acquisition system 100 can be constructed more cost-effectively.

[0072] Implementation Method 3

[0073] Considering Figure 6In step S406, if the same abnormality occurs again within a short period of time after the device is restarted, no inspection instruction is issued.

[0074] Figure 11 This is a flowchart illustrating the data transmission and reception processing in the device data acquisition system 100 of Embodiment 3. Furthermore, in this case, Figure 11 In step S202, after determining that a control device is present, it is determined whether there is no identical transmission data recently (step S211). If there is no identical transmission data, proceed to step S203. If there is identical transmission data, proceed to step S206.

[0075] In this way, if the abnormality occurs even after restarting the equipment, maintenance personnel can be dispatched to deal with the abnormality quickly.

[0076] In addition, in this case, if the data storage management device 104 adds the content of the current transmission data to a data group based on previously stored transmission data, it will be easier to perform anomaly analysis and investigate the cause thereafter.

[0077] The preferred embodiments have been described in detail above. However, the embodiments are not limited to these embodiments, and various modifications and substitutions can be made to the above embodiments without departing from the scope of disclosure.

[0078] Furthermore, when the number, quantity, quantity, range, etc., of each element are mentioned in the embodiments, the apparatus of this disclosure is not limited to the mentioned numbers, unless specifically stated or obviously determined in principle. Furthermore, the structures described in these embodiments are not essential, except when specifically stated or obviously determined in principle.
