Embodiment Construction

[0019] Refer to attached Figure 1~3 , the data acquisition gateway based on contract energy management in the present invention has a data acquisition circuit, a communication protocol conversion circuit, a TCP / IP interface, a 16-port RS-485 communication interface and an RS-232 interface module, and the 16-port RS-485 communication interface There are 16 485 communication interfaces, which can be connected to 16 energy consumption measurement devices. The communication protocols of each energy consumption measurement device are different. The gateway sends different data collection instructions according to the communication protocols of each energy consumption measurement device, and stores the data in on the gateway. The setting of communication protocol can be input through TCP / IP interface or RS-232 interface and setting software. The TCP / IP interface or RS-232 interface can be connected to a communication device with the same interface, and the collected data can be tr...

Abstract

The invention discloses an energy performance contracting-based data acquisition gateway, which relates to equipment for automatically remotely acquiring and transmitting the energy consumption data of an energy utilization department. The energy performance contracting-based data acquisition gateway comprises a data acquisition circuit, a communication protocol conversion circuit, a transmission control protocol (TCP) / Internet protocol (IP) interface, 16 RS-485 communication interfaces and an RS-232 interface module, wherein the 16 RS-485 communication interfaces are 16 485 communication interfaces; the RS-232 interface module adopts a 232 interface chip U22; the data acquisition circuit is provided with 485 interface chips U1 to U16, analogue switches U17 to U20, a singlechip U21, the 232 interface chip U22, the 485 interface chip U23 and an Ethernet interface chip U24; and the RXD ends, TXD ends, RE ends and DE ends of the 485 interface chips U1 to U16 are connected with the singlechip U21 by the analogue switches U17 to U20 respectively. The energy performance contracting-based data acquisition gateway saves singlechip serial port resources, and reduces the cost.

Description

technical field [0001] The data acquisition gateway based on contract energy management of the present invention relates to a device for remote and automatic acquisition and transmission of energy consumption data of energy consumption units. Background technique [0002] As the Chinese government attaches great importance to energy conservation, environmental protection and green economy, various enterprises and institutions put energy conservation and emission reduction on the agenda. In view of the advantages of contract energy management mode for energy-consuming units with no investment and low risk, more and more The energy-consuming units hand over the energy-saving transformation work to professional contract energy management companies. However, traditional manual meter reading and statistical reports cannot guarantee the real-time and consistency of energy consumption data of energy-consuming units, and economic disputes are likely to arise during contract executio...
