Description

The present invention relates to a device monitoring system and a device monitoring method.

Conventionally, device monitoring systems have been developed that transmit information acquired by sensor devices to a server device via a communication network. Data obtained from the sensor device is processed by the server device to monitor the state of the device to which the sensor device is attached. For example, the device monitoring system 100 of Patent Document 1 includes a sensor device 102, an agent device 104, a communication network 106, a server device 108, and a management device 110 (FIG. 4). The agent device 104 and the management device 110 exchange authentication identification information and the like via the communication network 106, and if the agent device 104 is authenticated, data can be sent from the agent device 104 to the server device 108.

If the communication network 106 of Patent Document 1 uses a cellular communication network including LTE (Long Term Evolution), a SIM (Subscriber Identity Module Card) card is required. The SIM card stores SIM identification information in a storage section. SIM identification information is printed anywhere on the SIM card. By linking the SIM identification information with the identification information of the agent device 104 or the like and storing it in the server device 108, it becomes possible to delete the SIM card on the web page of the operator of the communication network 106.

However, the SIM identification information printed on the SIM card is very small, and it is easy for the SIM identification information to be misread, creating a burden on workers. If the SIM identification information is read incorrectly, corrections will be required, which will reduce yield. If the SIM card is to be replaced, the information linking the SIM identification information and the agent device 104 must be stored again, which is a burden on the operator. A similar workload occurs when replacing a SIM card due to its lifespan.

An object of the present invention is to provide a device monitoring system and a device monitoring method that can easily store data including SIM identification information.

In order to solve the above problems, a device monitoring system and a device monitoring method according to the present invention have the following configuration.

The device monitoring system of the present invention is a device monitoring system that acquires a sensor signal with a sensor device and communicates it from a communication device to a server device via a communication network. The communication device communicates the transmission data with a SIM card including SIM identification information, and a transmission data generation unit that generates transmission data including communication device identification information included in the communication device and SIM identification information of the SIM card. and a communication module for transmitting data to a network. The server device includes a storage unit and a processing unit that causes the storage unit to store link information between communication device identification information and SIM identification information.

The device monitoring method of the present invention includes the steps of generating transmission data including SIM identification information included in the SIM card and communication device identification information included in the communication device, and transmitting the transmission data from the communication device to the server via a communication network. and a step of storing linking information between communication device identification information and SIM identification information in a storage unit in the server device.

According to the present invention, data including the SIM identification information can be automatically stored in the server device by transmitting the SIM identification information as transmission data to the server device. There is no need to store SIM identification information as in the past, and there is no need to store it by mistake. When replacing the SIM card, the business that manages the server device directly ships the SIM card to the worker of the device to which the sensor device is attached, and the worker can replace the SIM card. There is no need for the business operator managing the server device to replace the SIM card, and downtime of the device monitoring system can be kept to a minimum.

FIG. 2 is a diagram showing the configuration of Patent Document 1.

A device monitoring system and a device monitoring method according to an embodiment of the present invention will be described with reference to the drawings.

The device monitoring system 10 of the present application shown in FIG. 1 is a system that transmits a signal detected by a sensor device attached to an arbitrary device to a server device 18 via a communication network 16. For example, a sensor device is attached to a hydraulic device used in the gate device of the truck 20, and the state of the hydraulic device is detected by the sensor device. There may be a plurality of trucks 20. The sensor signal detected by the sensor device is transmitted to the server device 18 via the communication network 16 and processed by the server device 18.

The device monitoring system 10 includes a sensor device 12, a communication device 14, a communication network 16, and a server device 18 (FIG. 2).

The sensor device 12 is a pressure sensor, a thermometer, an ammeter, a rotation speed meter, or the like. For example, when detecting the state of the hydraulic device, the sensor signals detected by the sensor device 12 include the pressure of the liquid, the temperature of the liquid, the current flowing to the motor, the rotation speed of the pump, and the like. Each sensor device 12 has sensor device identification information, which is stored in the server device 18 as first linked information as described later. The sensor device identification information may be printed anywhere on the sensor device 12.

The communication device 14 is a device to which a sensor signal detected by the sensor device 12 is input and communicates with the communication network 16 . The communication device 14 includes a control circuit 22, a communication module 24, and a SIM card 26.

The control circuit 22 is an arithmetic circuit such as a CPU (Central Processing Unit) or a PLC (Programmable Logic Controller). The control circuit 22 functions as a signal collection section 28 , a SIM identification information acquisition section 30 , a transmission data generation section 32 , and a data transmission section 34 . Furthermore, communication device identification information is stored in a storage section (not shown) inside the control circuit 22 . Communication device identification information may be printed at an arbitrary position on the control circuit 22.

The signal collection unit 28 acquires the signal acquired by the sensor device 12 from the sensor device 12. The SIM identification information acquisition unit 30 acquires SIM identification information from the communication module 24. The transmission data generation unit 32 acquires the sensor signal acquired by the communication device 14, the SIM identification information acquired by the SIM identification information acquisition unit 30, and the communication device identification information, and generates transmission data. The data transmitter 34 transmits transmission data to the communication module 24.

The SIM identification information acquisition unit 30 acquires SIM identification information in the first communication from the communication device 14 to the server device 18 after the communication device 14 is powered on. This is because it is necessary to turn off the power to the communication device 14 when installing the SIM card 26. The communication device 14 is powered on after the SIM card 26 has been installed.

The communication module 24 is a device that establishes network communication using the SIM identification information of the SIM card 26 and transmits transmission data to the server device 18 via the communication network 16.

The SIM card 26 includes a storage section, and SIM identification information for using the communication network 16 is stored in the storage section. The SIM identification information may be printed at any position on the SIM card 26. This SIM identification information includes unique information allocated to each SIM card 26, information for using the communication network 16, and information on the operator of the communication network 16. These SIM identification information are sent from the base station 36 of the operator of the communication network 16 to the switching center 38 (FIG. 1), and the switching center 38 determines whether the communication network 16 can be used based on the SIM identification information. If it is determined that the communication network 16 is available, the communication network 16 can be used. Therefore, the communication module 24 is a device for using a cellular communication network including LTE and the like.

The communication device 14 may include a sensor board. The control circuit 22, communication module 24, and SIM card 26 of the communication device 14 are mounted on a board. A connector for connecting the sensor device 12 and the communication device 14 is mounted on the board as necessary. Furthermore, the communication device 14 can be variously used as long as it is a device that can utilize a cellular communication network using the SIM card 26 as described above. For example, the communication device 14 can be a gateway device, a laptop computer, a tablet, a smartphone, or the like.

The communication network 16 is a communication network for transmitting transmission data. Communication network 16 includes base stations 36 , switching centers 38 , and communication networks 40 . Communication device 14 is wirelessly connected to base station 36 . The base station 36 and the exchange 38 are connected by wire. The switching center 38 is a device for permitting communication (establishing communication) using SIM identification information. If communication is permitted by the switching center 38, transmission data can be transmitted via the communication network 40 via the switching center 38. The communication network 40 is a communication network such as the Internet. Server device 18 is connected to communication network 40 .

The server device 18 functions as a receiving section 42, a processing section 44, and a display section 46. The receiving section 42 receives the transmission data and transmits the transmission data to the processing section 44 . The processing unit 44 performs necessary processing on the transmission data. The process performed by the processing unit 44 determines whether there is an abnormality in the hydraulic device from the sensor signal included in the transmitted data. For example, if the pressure of the liquid is low, it is determined that there is a liquid leak from the hydraulic device. The display unit 46 displays the data processed by the processing unit on a display device.

Two pieces of association information 50 and 52 are stored in the storage unit 48 of the server device 18. The first association information 50 is information that associates sensor device identification information and communication device identification information, and the second association information 52 is information that associates communication device identification information and SIM identification information identification information. The transmitted data includes communication device identification information, and the sensor device can be searched based on the communication device identification information. The first association information 50 is stored in the storage unit 48 of the server device 18 by an operator as in the conventional manner. The second association information 52 is stored by the processing unit 44 using the SIM identification information and communication device identification information included in the transmission data. In the present application, the second association information 52 can be automatically stored, and will not be stored by mistake.

Next, a device monitoring method using the device monitoring system 10 will be explained. (1) The worker attaches the SIM card 26 to the communication device 14 and turns on the power to the communication device 14. By turning on the power in this manner, the SIM identification information acquisition unit 30 acquires SIM identification information from the SIM card 26 via the communication module 24 and sends the SIM identification information to the transmission data generation unit 32. The SIM identification information acquisition unit 30 acquires SIM identification information when the communication device 14 is powered on, and does not acquire SIM identification information thereafter.

(2) The transmission data generation unit 32 generates transmission data including SIM identification information and communication device identification information, and sends it to the data transmission unit 34. The data transmitter 34 sends transmission data to the communication module 24.

(3) The communication module 24 establishes communication with the communication network 16 using the SIM identification information, and transmits the transmission data to the server device 18. Establishment of communication involves transmitting SIM identification information from the base station 36 of the communication network 16 to the switching center 38, and the switching center 38 using the SIM identification information to authorize use of the communication network 16. If use of the communication network 16 is permitted, the data sent by the communication module 24 is sent to the server device 18 via the communication network 40. The transmission data is received by the reception unit 42 of the server device 18 .

(4) Transmission data is sent from the receiving section 42 to the processing section 44, and the transmission data is subjected to predetermined processing in the processing section 44. The process performed by the processing unit 44 is to generate second association information 52 from the communication device identification information and SIM identification information included in the transmission data, and to store it in the storage unit 48 .

Through the above steps, information including SIM identification information is stored in the storage unit 48 of the server device 18. Since the SIM identification information is automatically stored when the communication device 14 is powered on, there is no need for the operator to read and store the SIM identification information written on the SIM card 26.

(5) Furthermore, the sensor device 12 detects the state of the device to which the sensor device 12 is attached. If the sensor device 12 is attached to the hydraulic system of the truck 20, the sensor device 12 may be a pressure gauge, a thermometer, an ammeter, a revolution counter, or the like. The sensor device 12 detects the pressure of the liquid, the temperature of the liquid, the current flowing to the motor, the rotation speed of the pump, and the like.

(6) The signal collection unit 28 acquires the sensor signal from the sensor device 12 and sends the sensor signal to the transmission data generation unit 32.

(7) The transmission data generation unit 32 generates transmission data including a sensor signal and communication device identification information, and sends it to the data transmission unit 34. The data transmitter 34 sends transmission data to the communication module 24.

(8) Similarly to the above, the transmission data is received by the receiving unit 42 of the server device 18 from the communication module 24 via the communication network 16.

(9) Transmission data is sent from the receiving unit 42 to the processing unit 44, and the transmission data is subjected to predetermined processing in the processing unit 44. For example, if the transmission data includes liquid pressure, the processing unit 44 determines whether the liquid pressure is within a predetermined range, and determines that there is an abnormality if it is not within the predetermined range. If the liquid pressure is low, it is determined that there is a liquid leak, and if the liquid pressure is high, it is determined that there is an abnormality in the valve, etc. In determining abnormality, it is preferable to comprehensively judge not only pressure but also temperature, current, and rotation speed.

The processing results performed by the processing section 44 may be displayed by the display section 46 on a display device. The sensor device can be searched from the first association information 50 using the communication device identification information included in the transmission data. Furthermore, the operating status of the device to which the sensor device 12 is attached can be confirmed from the sensor signal included in the transmitted data. The user also checks the second association information 50 displayed on the display device, accesses the server of the communication carrier connected to the communication network 16, searches the website of the communication network carrier for SIM identification information, and checks the SIM card information. It is also possible to carry out procedures such as deletion of 26.

As described above, in the present application, communication device identification information and SIM identification information can be automatically stored in the storage unit of the server device 18. There is no need for the worker to read the SIM identification information of the SIM card 26, and the work efficiency of the worker is improved. It is possible to prevent an operator from registering the second association information 52 by mistake, and the yield rate is improved. If the SIM card 26 is to be replaced for some reason, the business that manages the server device 18 will ship the SIM card 26 to the operator of the device to which the sensor device 12 is installed, and that worker will replace the SIM card 26. Can be done. There is no need for the business operator who manages the server device 18 to go to the location where the device to which the sensor device 12 is attached to replace the SIM card 26 is located, and downtime of the device monitoring system 10 can be kept to a minimum.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment. For example, when the communication device 14 is powered on, the SIM identification information is transmitted to the server device 18, but the sensor signal and the communication device identification information may be included in the data transmitted at that time.

The sensor device 12 is not limited to only detecting the state of the device to which the sensor device 12 is attached. For example, sensor device 12 may be a GPS that measures the position of truck 20. The location of truck 20 can be sent to server device 18 for monitoring.

The control circuit 22 may include a processing section 62, as in the device monitoring system 60 in FIG. The processing section 62 of the control circuit 22 processes the sensor signal obtained from the sensor device 12. Although the transmission data explained in FIGS. 1 and 2 included sensor signals, the device monitoring system 60 includes data obtained by processing the sensor signals in the transmission data. The processing unit 22 of the server device 18 does not process the sensor signal, but the processing unit 62 of the control circuit 22 processes the sensor signal. In the present application, the sensor signal may be processed by either the control circuit 22 or the server device 18. The processing unit 22 of the server device 18 stores at least the second association information 52 in the storage unit 48.
