Embodiment Construction
[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many of the details listed in the specification are only for readers to have a thorough understanding of one or more aspects of the present invention, and these aspects of the present invention can be implemented even without these specific details.
[0024] The inventors of the present invention consider that the traditional monitoring data for the operation status of industrial equipment is generally transmitted by wire, the system wiring is intricate, the site construction is large, and a lot of manpower and material resources are required. Data transmission mostly adopts a question-and-answer communication method. The master station sends instructions to each sub-station in turn, and the designated sub-stat...

The invention discloses a monitoring data acquisition and transmission device which comprises a data acquisition unit, a control unit and a wireless transmission unit. The data acquisition unit is used for acquiring monitoring data and sending the monitoring data to the control unit. The control unit is used for coding the monitoring data according to a user-defined protocol and controlling the wireless transmission unit to initiatively upload the coded monitoring data to an upper computer. The monitoring data acquisition and transmission device adopts a wireless mode to initiatively upload the monitoring data to the upper computer, and thus the shortcomings of complicated wire arrangement, high cost, low communication reliability and likely interruption of a traditional transmission mode are solved. In addition, the device adopts the user-defined protocol to code the monitoring data, and the upper computer can accurately obtain monitoring data without depending on the protocols provided by instrument manufacturers.
Description
technical field [0001] The invention relates to the field of electric power technology, in particular to a monitoring data collection and transmission device. Background technique [0002] At present, the monitoring data for the operation status of industrial equipment is generally transmitted through wired methods. The wiring of the system is intricate, and the amount of on-site construction is large, which requires a lot of manpower and material resources. Data transmission mostly adopts a question-and-answer communication method. The master station sends instructions to each sub-station in turn, and the designated sub-station transmits some data, and only the sub-station that is inquired will respond. This communication method has extremely high requirements on the configuration of the master station and the communication efficiency is low. A certain sub-station must wait for the transmission of the sub-station in front before it can transmit data. In practical applicati...
