Abstract

The present application relates to the technical field of industrial data processing, and in particular relates to a field data processing method, apparatus and system, which are used to realize the timely processing of field data. In the embodiments of the present application, a field data processing apparatus located on an industrial site of an industrial system receives field data from at least a field apparatus on the industrial site, and processes the received field data and provides the processing result of the field data. In this way, untimely processing of field data can be avoided.

First claim

The invention claimed is:

1. An apparatus control method, usable to control a field data processing apparatus on an industrial site of an industrial system, the apparatus control method comprising:
receiving, at the field data processing apparatus, field data from at least a field apparatus located on the industrial site and generating field data, processing the field data and providing a processing result of the field data to a server or displaying the processing result of the field data on the industrial site; and
sending a field data acquisition permission request message to the server to request a right to acquire the field data; and
receiving, at the server located in the industrial system and connected with the field data processing apparatus, the field data acquisition permission request message, determining whether the field data processing apparatus has the right to acquire the field data, sending upon the field data processing apparatus being determined to have the right to acquire said field data, a field data acquisition permission acknowledgement message to the field apparatus, the field data acquisition permission acknowledgement message being usable to indicate that the field data processing apparatus has the right to acquire the field data; and
receiving, at the field data processing apparatus, the field data acquisition permission acknowledgement message, and determining that the field data processing apparatus has the right to acquire the field data according to the field data acquisition permission acknowledgement.

2. The apparatus control method of claim 1 , wherein the receiving of the field data acquisition permission request message includes:
receiving, via the server, the field data acquisition permission request message containing identification of the field data processing apparatus, and
acquiring, via the server, the identification of the field data processing apparatus from said field data acquisition permission request message;
the apparatus control method further comprising:
sending, via the server, upon the determining indicating that the field data processing apparatus has the right to acquire the field data, a first notification message to at least the field apparatus, the first notification message being usable to notify at least the field apparatus that the field data processing apparatus with the identification has the right to acquire the field data.

3. The apparatus control method of claim 1 , wherein the receiving of the field data acquisition permission request message includes:
receiving, via the server, the field data acquisition permission request message containing identification of the field data processing apparatus, and
acquiring, via the server, the identification of the field data processing apparatus from said field data acquisition permission request message;
the apparatus control method further comprising:

sending via the server, upon the determining indicating that the field data processing apparatus has the right to acquire the field data, a second notification message to a field control apparatus, the second notification message being usable to notify the field control apparatus that the field data processing apparatus with the identification has the right to acquire the field data, wherein the field control apparatus is configured to control the sending of the field data from at least the field apparatus.

4. An industrial system, comprising:
at least a field apparatus, located on an industrial site of the industrial system;
a field data processing apparatus, located on the industrial site, the field data processing apparatus being configured to:
receive field data from at least a field apparatus on the industrial site, process the field data, and
provide a processing result of the field data; and

a server, located in the industrial system and connected with the field data processing apparatus;
the field data processing apparatus being configured to:
send a field data acquisition permission request message to the server to request a right to acquire the field data; and

the server being configured to:
receive the field data acquisition permission request message, and
determine whether the field data processing apparatus has the right to acquire the field data, and
send, upon the field data processing apparatus being determined to have the right to acquire said field data, a field data acquisition permission acknowledgement message to the field apparatus, the field data acquisition permission acknowledgement message being usable to indicate that the field data processing apparatus has the right to acquire the field data, and the field data processing apparatus being further configured to:
receive the field data acquisition permission acknowledgement message,
determine that the field data processing apparatus has the right to acquire the field data according to the field data acquisition permission acknowledgement message, and
send processed field data from the field data processing apparatus to the server.

5. A server, the server being configured to control a field data processing apparatus on an industrial site, the server comprising:
a receiver, to receive a field data acquisition permission request message from the field data processing apparatus on the industrial site, the field data acquisition permission request message being usable for the field data processing apparatus to request a right to acquire field data from at least a field apparatus on the industrial site;
a processor, to determine whether the field data processing apparatus has the right to acquire the field data;
a sender, to send upon the field data processing apparatus being determined to have the right to acquire said field data, a field data acquisition permission acknowledgement message to the field apparatus, the field data acquisition permission acknowledgment message being usable to indicate that the field data processing apparatus has the right to acquire the field data; and
receive processed field data, associated with the field apparatus, from the field data processing apparatus.
