Embodiment Construction

[0046] The method of the invention selects embedded hardware with low power consumption, and controls the working sequence of different parts by sub-modules and sub-sequences, thereby greatly reducing the power consumption of the whole machine while ensuring overall high performance. The basic principle is as follows: RTU contains many functions, which can be logically divided into power control module, data acquisition module and main control module, and can be divided into waiting time and working time in terms of timing. All functions of RTU do not happen at the same time. Subdivided into independent working hours of different functional modules, therefore, the whole machine, sub-module and timing control can be carried out to reduce power consumption. The basic method of the present invention is: first logically divide the functional modules and sort out the interrelationships, then determine the working sequence and mutual combination relationship of each module from the t...

Abstract

The invention discloses a high-performance hydrology and water resource RTU (remote terminal unit) based on an ARM (advanced RISC machine) framework and a power consumption control method of the RTU. A plurality of high-performance embedded type CPUs (central processing units) are adopted to constitute a host system of the RTU, a logical structure of the host system consists of three main function modules: a main control module, a data acquisition module and a power supply control module; each module is divided into a plurality of function sub-modules, and each function sub-module only accomplishes single functional mask; and the modules and the function sub-modules thereof are combined and operate alternatively under the unified sequential control, the minimum number of operating modules at any time is guaranteed, and accordingly, the overall power consumption is optimal. With the adoption of the scheme, the overall power consumption is greatly reduced while the overall performance of the terminal unit is guaranteed.

Description

[0001] technical field [0002] The invention belongs to the field of energy consumption control methods for data acquisition telemetry terminals, and specifically relates to a high-performance hydrology and water resources telemetry terminal based on an ARM architecture and a power consumption control method thereof, and is especially suitable for long-term RTU working in the field without mains power Energy consumption control management. Background technique [0003] The hydrological and water source telemetry terminal (RTU) needs to work for a long time in the field without mains power, so the low power consumption of the whole machine is a key indicator, and domestic and foreign manufacturers have made various efforts on this indicator. At present, methods such as selecting low-power devices or simplifying the functions of the whole machine are generally adopted to reduce power consumption. Although the selection of low-power devices can greatly reduce the power consum...
