Description

[Technical field]

[0001] The present invention relates to an environmental load determination system. [Background technology]

[0002] For example, control systems are used for monitoring and controlling various facilities attached to buildings and plants, and furthermore, device management devices are used (Patent Document 1).For example, device management devices exchange signals with field devices, such as process devices and various sensors, installed at the site and connected via a network such as a field bus, and perform calibration by setting parameters, for example, and display diagnostic results regarding the operating status of the field devices.

[0003] On the other hand, field devices are affected by various factors from the environment in which they are installed, and understanding these factors is important for managing field devices. In order to implement such management, it is important to measure and determine the environmental load that the field device is subjected to. For example, if the vibration of the field device from the environment exceeds an allowable value, it can be determined that the field device is not operating normally.

[0004] [Patent Document 1] JP 2015-090595 A Summary of the Invention [Problem to be solved by the invention]

[0005] In the above-mentioned judgment, information on the allowable environmental load of the field device is required. This type of information is stored (stored) in a device management device or the like, and at the site where the field device is installed, communication is established with the device management device to obtain the information. On the other hand, an instrument that measures vibration generally does not have a function to establish communication with the device management device. For this reason, the allowable environmental load is obtained using a setting device that performs engineering work on the field device at the site, and the judgment is made by comparing the allowable environmental load with the measurement result measured manually by the instrument. Thus, there has been a problem in the past that it is time-consuming to judge the environmental load on a field device.

[0006] The present invention has been made to solve the above problems, and has an object to make it possible to determine the environmental load imposed on a field device without much effort. [Means for solving the problem]

[0007] The environmental load determination system according to the present invention is an environmental load determination system that measures the environmental load received from a site where a field device is installed and determines the impact of the field device, and includes a mobile terminal and a server. The mobile terminal includes a sensor configured to measure the environmental load of the field device by bringing the mobile terminal into contact with or approaching the field device, a readout circuit configured to read from the field device device information for identifying the field device including attributes of the field device, a terminal transmitting circuit configured to transmit the device information read by the readout circuit to a server, a terminal receiving circuit configured to receive the environmental load allowable value transmitted from the server, and a determination circuit configured to determine the degree of impact of the environmental load received by the field device by comparing the environmental load measurement value measured by the sensor with the environmental load allowable value received by the terminal receiving circuit. The server includes a storage device configured to store an allowable value for the environmental load corresponding to the field device, a server receiving circuit configured to receive device information transmitted from the mobile terminal, an extraction circuit configured to extract from the storage device an environmental load allowable value corresponding to the device information received by the server receiving circuit, and a server transmitting circuit configured to transmit the environmental load allowable value extracted by the extraction circuit to the mobile terminal.

[0008] In one example of the configuration of the environmental load determination system, the sensor measures vibrations of the field device. Effect of the Invention

[0009] As described above, according to the present invention, the environmental load of a field device is measured by a sensor of a portable terminal, and the measured environmental load value is compared with the received environmental load allowable value to determine the degree of influence of the environmental load on the field device. Therefore, the environmental load on the field device can be determined without much effort. [Brief description of the drawings]

[0010] [Figure 1] FIG. 1 is a diagram showing the configuration of an environmental load determination system according to an embodiment of the present invention. [Diagram 2] FIG. 2 is a timing chart for explaining an example of the operation of the environmental load determination system according to the embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] An environmental load determination system according to an embodiment of the present invention will be described below with reference to Fig. 1. This environmental load determination system is a system that measures the environmental load received from the site where a field device 121 is installed and determines the influence received by the field device 121, and includes a mobile terminal 101 and a server 110.

[0012] The mobile terminal 101 includes a sensor 102 , a read circuit 103 , a terminal transmitting circuit 104 , a terminal receiving circuit 105 , a determination circuit 106 , a memory 107 , an input unit 108 , and a display unit 109 .

[0013] The sensor 102 measures the environmental load of the field device 121 by contacting the sensor 102 with the field device 121. The sensor 102 measures, for example, the vibration of the field device 121. For example, the vibration of the field device 121 can be measured by a person carrying the mobile terminal 101 bringing the mobile terminal 101 into contact with the target field device 121 and operating the sensor 102. The sensor 102 can be a sensor that measures various physical quantities such as acceleration, inclination (horizontal), electromagnetic wave intensity, sound wave / ultrasonic wave, illuminance, temperature, humidity, and radiation amount. If the physical quantity to be measured can be measured by bringing the mobile terminal 101 into close proximity to the field device 121, the mobile terminal 101 having a built-in sensor for measuring the physical quantity can be brought into close proximity to the field device 121 without contacting the field device 121.

[0014] The read circuit 103 reads out device information for identifying the field device 121, including attributes of the field device 121, from the field device 121. For example, in a state where the mobile terminal 101 and the field device 121 are electrically connected with a predetermined connection cable, the read circuit 103 is operated by a person in charge operating the input unit 108, whereby the read circuit 103 reads out the device information from the field device 121.

[0015] Also, the mobile terminal 101 and the field device 121 can be electrically connected by well-known near field radio communication (NFC), and the read circuit 103 can read device information from the field device 121. For example, each of the mobile terminal 101 and the field device 121 has an NFC function unit that performs near field radio communication, and a connection request by NFC communication in the NFC function unit of the mobile terminal 101 is received by the NFC function unit of the field device 121, thereby establishing near field radio communication between the two. After establishing near field radio communication in this manner, the read circuit 103 reads device information from the field device 121.

[0016] The terminal transmitting circuit 104 transmits the device information read by the reading circuit 103 to the server 110. The terminal receiving circuit 105 receives the allowable environmental load value transmitted from the server 110. The received allowable environmental load value is temporarily stored in the memory 107, for example.

[0017] For example, the mobile terminal 101 is connected to the Internet network 131 via a base station 141 connected by wireless communication, and is capable of communicating with a server 110 connected to the Internet network 131 .

[0018] The determination circuit 106 compares the environmental load measurement value measured by the sensor 102 with the allowable environmental load value received by the terminal receiving circuit 105 to determine the degree of the influence of the environmental load on the field device 121. The determination circuit 106, for example, reads out the allowable environmental load value temporarily stored in the memory 107 and compares it with the environmental load measurement value. The determination result by the determination circuit 106 is displayed on the display unit 109, for example. The input unit 108 and the display unit 109 can be touch panels.

[0019] The server 110 includes a storage device 111 , a server receiving circuit 112 , an extracting circuit 113 , and a server transmitting circuit 114 .

[0020] The storage device 111 stores an allowable value for an environmental load according to the field device 121. The storage device 111 may be, for example, a hard disk drive (HDD). The storage device 111 may also be a solid state drive (SSD).

[0021] The server receiving circuit 112 receives the device information transmitted from the mobile terminal 101. The extracting circuit 113 extracts from the storage device 111 the allowable environmental load value corresponding to the device information received by the server receiving circuit 112. The server transmitting circuit 114 transmits the allowable environmental load value extracted by the extracting circuit 113 to the mobile terminal 101.

[0022] Next, an example of the operation of the environmental load determination system will be described with reference to the timing chart of FIG.

[0023] First, at T101, the person in charge brings the mobile terminal 101 into contact with the field device 121. Furthermore, the person in charge operates the input unit 108 to operate the sensor 102, thereby measuring the vibration of the field device 121. After the vibration of the field device 121 is measured by the sensor 102 by starting the determination application, the person in charge electrically connects the mobile terminal 101 to the field device 121, and operates the read circuit 103 to read device information from the field device 121.

[0024] When the device information is read from the field device 121, in T103, the terminal transmitting circuit 104 transmits the device information read by the reading circuit 103 to the server 110. The device information transmitted to the server 110 is received by the server receiving circuit 112.

[0025] When the server receiving circuit 112 receives the device information, at T104 the extraction circuit 113 extracts the allowable environmental load value corresponding to the device information received by the server receiving circuit 112 from the storage device 111. When the extraction circuit 113 extracts the allowable environmental load value from the storage device 111, at T105 the server transmitting circuit 114 transmits the allowable environmental load value extracted by the extraction circuit 113 to the mobile terminal 101. The allowable environmental load value transmitted to the mobile terminal 101 is received by the terminal receiving circuit 105.

[0026] When the allowable environmental load value is received by the terminal receiving circuit 105, at T106 the determination circuit 106 compares the environmental load measurement value measured by the sensor 102 with the allowable environmental load value received by the terminal receiving circuit 105 to determine the degree of the influence of the environmental load on the field device 121. The determination result by the determination circuit 106 is displayed on the display unit 109.

[0027] In addition, the mobile terminal according to the above-mentioned embodiment is a computer device operated by a CPU (Central Processing Unit), and the functions of each of the above-mentioned circuits are realized by the CPU operating (executing) a program expanded in memory.

[0028] As described above, according to the present invention, the environmental load of a field device is measured by a sensor of a portable terminal, and the measured environmental load value is compared with the received environmental load allowable value to determine the degree of influence of the environmental load on the field device. Therefore, the environmental load on the field device can be determined without much effort.

[0029] It should be noted that the present invention is not limited to the above-described embodiments, and it is apparent that many modifications and combinations can be made by a person having ordinary knowledge in the art within the technical concept of the present invention.
