It can be seen that the identity of each post in the plant is different, as are the requirements and tasks.
The principle of the relationship between the existing production stations and the plant control system is shown in fig. 1, wherein M1-Mn in fig. 1 is a field device, AOC1-AOCn is a machine-side operation box corresponding to the field device, J1-Jx are instrumentation devices arranged at instrumentation nodes, such as temperature, pressure, flow rate, etc., KM1-KMn are actuating elements, such as contactors, etc., for controlling the operating state of each field device, and C3, Cn are field display units of part of the instrumentation nodes.
During the production process, the field operation staff pay attention to the production operation parameters, and the production operation parameters are detected by a detection instrument (J1-Jx) arranged in the production process. As shown in fig. 1, in the existing production process parameter display system, corresponding meters J1-Jn are arranged according to production requirements at different links in the production process of a factory to detect production parameters such as temperature, pressure, flow and weight required to be detected in the production process of the factory, relevant signals are collected by the detection meters and then sent to a factory computer control system through signal lines, and part of the production parameters required to be displayed on a detection site can be displayed through display units (AOC1 and AOC2) carried by the meters. Namely, the staff of the field operation post sees the production parameters detected by the staff through the detection instrument provided with the display unit.
During the production process, the maintenance post staff of the equipment needs to operate the equipment on site. As shown in FIG. 1, the equipment M1 is powered by a power line, and the starting and stopping of the equipment are controlled by a starting element KM 1; the device KM1 received start/stop instructions from the plant computer control system via the signal system line. The on-board operation box AOC1 of the equipment M1 transmits an on-board operation request of a field maintenance post for personnel to a factory computer control system through a signal line, and finally, the on-board operation of the equipment is realized. Namely, a corresponding beside-machine operation box needs to be arranged near each existing device for operating the device on site.
In the production process, maintenance state of field equipment, spare part state and other information need to be inquired by maintenance post workers of the equipment; in addition, engineers in the plant need documentation such as design drawings for field devices. As shown in fig. 1, personnel at the relevant station (maintenance station, engineer) needs to refer to technical documents about field devices, and perform maintenance work on the devices in combination with the technical documents about the field devices.
As can be seen from fig. 1, the work of the staff at each station is related to the instrument control system, the electrical control system and the document management system of the plant, and each station needs to perform the related operation on the equipment (for example, the production parameters displayed by the instrument at the site operation station, which belongs to the instrument control system, the production parameters displayed by the instrument at the maintenance station, which belongs to the electrical control system, the machine-side operation of the equipment at the maintenance station, which belongs to the document system) attached to the system.
