Description

  The present invention remotely collects process data generated by a plurality of field devices distributed in a plant in a data collection center, and a patrol person patrols the field devices in a predetermined route and collects five sense information. It relates to the inspection system.

  FIG. 3 is a functional block diagram illustrating a configuration example of a conventional inspection inspection system. The plurality of field devices 10 to 50 distributed in the plant installation sites P1 to P5 are each provided with a wireless module for remote communication.

Process data generated by each of the plurality of field devices 10 to 50 is transmitted to the data collection center 60, which is a higher-level device, by remote communication R1 to R5 . Further, the plurality of field devices 10 to 50 receive commands and settings from the host device. Patent Document 1 discloses a technical disclosure of a field device including a wireless modem.

  The data collection center 60 includes a CPU 61 that manages the overall functions, a remote wireless module 62 that communicates with the remote communications R1 to R5 from the field devices 10 to 50, a data processing means 63 that processes data communicated remotely, and predetermined received data. Data storage means 64 for storing the period, diagnosis means 65 for executing process abnormality diagnosis from the received data trend and the like, and alarm processing means 66 for outputting an alarm AL externally based on the diagnosis result.

  As described above, general process data can be collected and processed in real time in the data collection center 60 by remote communication, but can be sensed only by the human senses, for example, abnormal noise, odor, smoke, heat generation As for abnormalities such as vibrations, a human-mediated system is employed in which a patrol person periodically patrols the installation site of each field device and collects information.

  The patrol person 1 carries the check sheet 2 and the map 3 on which the patrol route is described, patrols the installation sites P1 to P5 of the field devices 10 to 50, enters the results of the five senses check into the check sheet 2, and completes the patrol. Submit the completed check sheet 2 to the manager 4 at times.

  The administrator 4 confirms and approves the check sheet submitted by the patrol person 1 and stores it for a predetermined period. Regarding the five senses abnormalities, the response by the check sheet may be delayed, so if the patrol checks for abnormalities that require emergency response at the inspection site, he / she notifies the administrator 4 via communication means such as a mobile phone. To do.

JP 2003-134030 A

The conventional inspection system has the following problems.
(1) After the patrol person 1 checks the field device 20 at the installation site P2, a place to be inspected to the field device 30 at the next remote installation site P3 is skipped to the field device 40 at the immediate installation site P4. There is no mechanism for checking whether the field device 30 has been inspected when the operator checks the absence of abnormality on the check sheet 2 and gives it to the administrator 4 without noticing that the field device 30 has not been inspected.

(2) In the system in which the sense information collection is based on the information entered in the check sheet 2, the collection of abnormality information lacks real-time characteristics. In the case of an emergency telephone contact system, it is necessary for the administrator 4 to be resident, and it is a human intervention system for remote collection of process data and an automatic management system, so that mistakes and response delays are likely to occur. .

(3) The patrol inspection system according to (1) or (2), wherein the field device communicates with a mobile terminal carried by the patrol person and acquires the five sense information from the mobile terminal.

(4) The data collection center includes a patrol point monitoring unit that monitors and warns the patrol person of missing patrol based on the five sense information data collected from the plurality of field devices. The inspection inspection system in any one of thru | or (3).

(5) The data collection center includes five sense abnormality monitoring means for alarming abnormality information exceeding a predetermined threshold based on five sense information data collected from the plurality of field devices. 4) Inspection inspection system in any one of.

(6) The inspection inspection system according to any one of (1) to (5), wherein the data remotely collected from the field device to the data collection center is by wireless means.

( 7 ) The inspection system according to ( 3), wherein the portable terminal includes means for communicating with the field device, acquiring output information of the data synthesizing means, and transmitting the information remotely to the data collection center. .

According to the present invention, the following effects can be expected.
(1) Normal or abnormal five sense information of each field device is transmitted together with process data, so it is possible to automatically warn of missing inspection by monitoring missing sense information input at the data collection center. .

(2) Normal or abnormal sense information of each field device is transmitted remotely along with process data, so the data collection center can automatically alert the sense of sense abnormality in real time and can be promptly handled by the host device. Become.

(3) In the patrol system of the present invention, the patrol person only needs to input the five senses information to the field device at the installation site, and a paper medium such as a check sheet is not necessary. In addition, abnormal information is automatically collected remotely at the data collection center, eliminating the need for a resident administrator.
