Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant equipment operating device for operating plant equipment such as a motor-using device and an opening adjustment valve connected to a control device.

[0002]

2. Description of the Related Art Conventionally, in a plant, an on-site operation panel is often installed for maintenance and adjustment near a plant device itself such as a pump and a blower, or near the plant device. This on-site operation panel is a box-type facility provided with a changeover switch, a push button switch, various instruments, and the like in a housing thereof, and is subjected to, for example, an all-weather type or a corrosion-resistant type according to the surrounding environment. . Each operation panel is connected to a control device to perform centralized control. At the time of maintenance and adjustment, the operator needs to change
By operating a push button switch and the like, a pump, a blower and the like are operated.

However, each on-site operation panel is made up of expensive parts such as instruments, and regular replacement of these parts and replacement in the event of a failure increase maintenance costs. In addition, the use of the on-site operation panel is limited to the operation state confirmation (visual observation) of the plant equipment and the operation at the time of maintenance / inspection of the plant equipment, and the use frequency is extremely low.

In recent years, for example, Japanese Patent Publication No.
As disclosed in Japanese Patent Application Publication No. 8 (1996) -1994, instead of the on-site operation panel, a connection terminal device (connector) connected to a control device by a transmission line is arranged near each on-site plant device. Then, by connecting the portable operation device to an arbitrary connection terminal device, the operation control of each plant device is easily performed from the site. A plant device operating device including a combination of such a control device and a portable operating device has been proposed.

[0005]

However, since the connection terminal device and the portable operation device are connected by a cable, the portable operation device cannot be freely carried and operated, which is inconvenient. In order to solve this problem, for example, it is conceivable to use wireless communication between the portable operation device and the control device.

On the other hand, when the plant equipment is manually operated alone at the site, various interlocks for safety are not taken, so that the user is generally close to the equipment and visually confirms the state of the equipment. Need to operate.

[0007] Therefore, it is necessary for an operator who operates on site to interlock such that only the plant equipment to be operated can be operated from his / her own portable operation device. This is because it is extremely dangerous to operate plant equipment at a distance irrespective of the worker.

In the case of the plant equipment operating device connected by the cable, an operator obtains the identification number of the plant equipment to be operated by connecting the portable operating device to a connection terminal device at a predetermined position on the transmission line. Can be Therefore, it is possible to take an interlock that restricts the operation, and it is possible to prevent an operator from erroneously specifying a plant device to be controlled.

However, when a wireless connection is provided between the portable operation device and the control device, it is difficult to take an interlock for preventing such erroneous operation. This is because, since the radio signal is transmitted in all directions, it is difficult to restrict the operation so that only the device in front of the worker can be operated.

The present invention has been made in view of such circumstances, and even when wireless communication is provided between the portable operation device and the control device, the portable operation device is located near the plant equipment to be controlled. It is an object of the present invention to provide a plant equipment operation device that enables plant equipment operation only when the position is within a certain specific range.

[0011]

In order to solve the above-mentioned problems, an invention according to claim 1 is a control device that performs centralized control on a plurality of plant equipment, and is portable and can operate the plant equipment. And a plant device operating device including at least one portable operating device.

In this plant equipment operating device, the position detecting means is provided on the portable operating device, and the current position of the portable operating device is detected. Further, the storage means stores a list of device operable locations in which the operable locations are designated for each plant device.

On the other hand, information is transmitted and received between the control device and the portable operation device by the transmission means. Then, operability determination means is provided, whereby it is determined whether or not the plant equipment is operable from the position information detected by the position detection means and the contents of the equipment operable place list, and the operability is determined. Only devices that have been determined to be available can be operated from the portable operation device.

At this time, the operation signal from the portable operation device is:
The information is transmitted to the control device by the transmission unit, and the operation of the device is performed under the control of the control device. Specifically, for example, it is used as follows.

First, an operator brings a portable operating device near plant equipment to be controlled individually and operates the portable operating device to perform an operation. The portable operation device obtains the current position (latitude / longitude) from the position detection means, and locks the control of the other devices as a control target that can operate only the corresponding device in the list of device operable locations from the current position. Even if a device to be operated is selected from the portable operation device, only the device to be controlled can be operated, and the operation can be permitted only when the user is near each plant device.

According to the present invention, such means are provided.
Even if wireless communication is used between the portable operation device and the control device, the operation of the plant device should be enabled only when the portable operation device is located in a certain specific range near the plant device to be controlled. And an interlock that prevents erroneous operation from the portable operation device can be realized.

According to a second aspect of the present invention, in the first aspect of the present invention, the portable operation device is configured such that the display means displays a state such as operation, stop, or failure of the plant equipment. I have.

The portable operating device is provided with operating means for operating the plant equipment, and the plant equipment whose status is displayed on the display means is operated by this means. Then, when the processing device selects a plant device to be operated, only the device determined to be operable by the operability determining device displays the state of the plant device from the display device. .

Therefore, the status of the inoperable device is not displayed on the display device, and the device cannot be operated by the operation device. This implements an interlock that prevents erroneous operation from the portable operation device.

Further, according to the invention corresponding to claim 3, in the invention corresponding to claim 2, when the plant equipment to be operated is selected, the status display is not limited by the processing means, Instead of the function, when the power of the portable operation device is turned on, the processing means processes only the device determined to be operable to display the status from the display means. Therefore, the status of the inoperable device is not displayed on the display means from the beginning of power-on, and an interlock that prevents erroneous operation from the portable operation device is realized.
