Problems solved by technology

[0003] However, the current SCADA monitoring software can only collect and monitor data for a specific device
If there are many types of equipment to be monitored, since the communication protocol and data transmission protocol used by each equipment are inconsistent, it is necessary to program each equipment separately and design different SCADA monitoring software, resulting in waste of resources

Embodiment Construction

[0012] Such as figure 1 Shown is a hardware architecture diagram of a preferred embodiment of the remote data acquisition system of the present invention. This system mainly comprises monitoring center 1, one or more SCADA servers 2 (the present embodiment is illustrated with 2 examples), database server 3, network server 4, client 5, data converter 6 and intelligent instrument 7, wherein , identical hardware is marked only once. The SCADA server 2 is connected to the monitoring center 1, the database server 3, the network server 4 and the data converter 6 through the network, and the data converter 6 is connected to one or more smart meters 7 through a serial port (such as an RS485 interface). Each smart meter 7 is connected with a device to be monitored ( figure 1 not shown in ) for collecting the data of the equipment to be monitored. Wherein, each area (such as area 1, area 2, area 3 and area 4) includes one or more devices to be monitored.

Abstract

The invention discloses a remote data acquisition method, which comprises the following steps that: a data acquisition parameter is set; an SCADA server transmits a data acquisition command to an intelligent instrument through a data converter every a period of time; the intelligent instrument returns the acquired data to the SCADA server through a data converter; the SCADA server checks and stores the acquired data, and judges whether the acquired data is normal, and if the acquired data is abnormal, the SCADA server transmits alarm information to a monitoring center and a client. The invention also provides a remote data acquisition system. Through the remote data acquisition method and the remote data acquisition system, the communication protocol and data transmission protocol of different equipment can be packaged into a unified interface, and the different equipment is accessed through the unified interface.

Description

technical field [0001] The invention relates to a data collection system and method, in particular to a remote data collection system and method. Background technique [0002] SCADA (Supervisory Control And Data Acquisition, data acquisition and monitoring control) system is a computer-based production process control and scheduling automation system, which can monitor and control the operating equipment on site to achieve data acquisition, equipment control, measurement , parameter adjustment and various signal alarm functions. [0003] However, the current SCADA monitoring software can only collect and monitor data for a specific device. If there are many types of equipment to be monitored, since the communication protocol and data transmission protocol used by each equipment are inconsistent, it is necessary to program each equipment separately and design different SCADA monitoring software, resulting in waste of resources. Contents of the invention [0004] In view o...
