Abstract

A dual-power-supply input data acquisition terminal comprises a power supply module, an energy data acquisition terminal, data acquisition units and a communication bus unit. The power supply module comprises a switching power supply and a dual-power-supply shifter, the dual-power-supply shifter comprises a main power supply, standby power supplies and an intermediate relay, the main power supply is divided into two branch circuits, one branch circuit is connected with the incoming line side terminal of a normally open switch of the intermediate relay, the other branch circuit is connected with a sucking coil of the intermediate relay, the standby power supplies are connected with the incoming line side terminal of a normally closed switch of the intermediate relay, and the outgoing line side terminal of the normally closed switch is connected with the outgoing line side terminal of the normally open switch in parallel and then connected with the switching power supply. Input of dual power supplies is achieved through the dual-power-supply shifter, when one power supply breaks down, the damaged power supply is automatically switched to the other power supply, operational reliability of the data acquisition terminal is improved, and the dual-power-supply input data acquisition terminal has the advantages of being low in power consumption and cost.

Description

technical field [0001] The invention relates to a data acquisition device, in particular to a data acquisition terminal with dual power supply input. Background technique [0002] Industry is the main area of ​​energy consumption, and industrial energy consumption accounts for more than 70% of the total energy consumption of the whole society. With the acceleration of industrialization and urbanization in my country, the task of industrial energy conservation and emission reduction during the "Twelfth Five-Year Plan" period is heavier and the pressure is greater. Applying information technology to build a digital energy management and control system, realize online monitoring of energy consumption, and accurately grasp the energy consumption of key industries, key enterprises, and key processes in real time is not only an inevitable requirement for enterprises to achieve refined energy conservation management and promote energy conservation and consumption reduction, It is a...
