230 MHz wireless communication speed self-adaptive designed-to-change collection terminal

Abstract

The invention relates to a 230 MHz wireless communication speed self-adaptive designed-to-change collection terminal. A signal output / input end of an interface unit is correspondingly connected with a first signal input / output end of an adapter plate, the signal output / input end of a processing and displaying unit is correspondingly connected with a second signal input / output end of the adapter plate, the signal output / input end of a communication unit is correspondingly connected with a third signal input / output end of the adapter plate, and a power supply output end is connected with power supply input ends of the adapter plate, the communication unit, the processing and displaying unit and the interface unit. The 230 MHz wireless communication speed self-adaptive designed-to-change collection terminal disclosed by the invention has the advantages of having a 230 HMz private network channel with three different speed and modulation modes of 2400bps-MSK (Minimum Shift Keying), 9600bps-GMSK (Gaussian Filtered Minimum Shift Keying) and 19200bps-4FSK (Frequency Shift Keying), different systems and field conditions can be adapted, and a GPRS (General Packet Radio Service) or CDMA (Code Division Multiple Access) public network channel can be used for logging in and operating through the issuing or the manual setting of a main station when the 230 HMz private network channel is not in existence or a public network channel needs to be used.

Description

technical field [0001] The invention relates to a 230MHz wireless communication rate self-adaptive variable acquisition terminal for a power load control system, and belongs to the technical field of wireless data transmission. Background technique [0002] Under the requirements of "full coverage, full collection, and full cost control" of the State Grid's "12th Five-Year" grid intelligent plan, the current electricity consumption information collection systems in various places have achieved considerable development. Article 18 of the national "Power Demand Side Management Measures" implemented in 2011 stipulates that users of more than 100KVA special transformers need to use control-type terminals. The recent State Grid documents have clarified the requirements of "special transformers using optical fibers and private networks". Therefore, the construction of the private network system will be rolled out in a wider range of the country, the market demand potential is huge...
