Centralized energy supply household metering and energy-saving control system

(On/Off Time Area Method)

Using the thermal inlet of each building as the settlement point, install a heat meter here to obtain the heating consumption data of the building as the basis for settlement.

Each end user is equipped with an indoor temperature controller to regulate the room temperature; Install intelligent valves on the inlet pipes of each end user to control the on/off flow of water, record the on/off time, and save data.

Collect end-user data through the building's data collection box, upload it to the data center, and the data center can control the heating behavior of end-users as needed.

The data center allocates costs based on heat meters and user heating data, in accordance with relevant policies and methods

The entire system is composed of monitoring computersNetwork base station, concentrator、Wireless data collectorIntelligent valveTemperature controller, thermal energy meterTo form a system that enables observation, payment management, recording, and querying of users' thermal energy usage.

Household metering is the core component of the entire billing and energy-saving control systemintelligenceValves to meet users' demand for energy-saving controlAt the same timeIntelligent valveCalculate the relevant data collected and upload it to the data center.When the user experiences abnormal usage or malfunctions,Intelligent valveIt will proactively send out a signal, and the monitoring system will immediately notify the management personnel.

systems software

The remote data collection and retrieval management software adopts a browser and server architecture, allowing users toWebpageSimply enter the server address on the browser to easily access management software remotely, without the need to install specialized software,Just as convenient as regular internet access.At the same time, it supports remote access from smartphones and handheld computers, facilitating users' mobile usage needs.

ZessenThe management software has the following functions：

1. Multi user and multi permission management. Different users can see the management content within their permission range to prevent information leakage.

2. Real time display of data. All copied data is displayed intuitively on the page.

3. Historical data query and summary. Support historical usage data queries and stage summaries for users, buildings, and residential areas, and can generateaccomplishexcelFormatted report.

4. Historical curve display. Can intuitively display the user's usage situation, facilitating production analysis and summary.

5. Alarm information management. Users can customize alarm conditions and search for abnormal situations such as table and pipeline failures.

6. Management of instrument replacement. After the replacement of the instrument, the system automatically records and corrects the readings, reducing losses and facilitating management.

7. Users can add community, building, and other information on their own to facilitate system maintenance and use to the greatest extent possible.

Network base station

Through the internet or3GThe network card directly connects to the Internet and transmits the data collected by the concentrator to the remote monitoring center.

function：

1. SDCard data storage function:8GCapacity ofSDThe card can store meter readings for one year.

2.Wired and wireless transmission methods are optional, providing standardsRJ45Network interface orUSBInterface (Connection)3GNetwork equipment).

concentrator

Responsible for receiving all data from the data collector. Can provide serial port connection to computerOr connect to the network base station to transmit data through the Internet.

function：

1. Network transmission breakpoint continuation function: When the network is unexpectedly interrupted, breakpoint continuation can be achieved to improve transmission efficiency.

2. Query function: Supports the client's query and meter reading function for a single meter.

Wireless Collector

The collector is integrated withM-BusBus485Bus interface, reading meter data. The data collector has both wireless data transmission and routing functions. When there are obstacles or the distance between nodes and base stations is too far, data can be automatically relayed through other nodes.

function：

1. Real time clock function, which can achieve automatic network timing and hourly readingread

2. Data storage function, realizing local storage of data to prevent losslose

3. Flexible configuration function, which can configure the reading time interval, connection table number, building number, and unit number function through the communication port

Intelligent temperature controlvalve

Intelligent valves are mainly used for centralized supplyabilityThe system accurately controls the flow rate of the heat medium according to actual needs without causing drastic temperature changes, achieving the goal of real-time and precise control of room temperature. The control valve is connected to the temperature controller, which integrates a temperature sensor for convenient construction: the temperature controller continuously samples and processes on-site data, sends control signals, controls the opening and closing of the electric ball valve, and provides heating for the room; Keep the room temperature consistently within the temperature range set by the thermostat.

heat meter

The thermal energy consumption in the collection area of the thermal energy meter serves as the basis for measurement and allocationFilters and manual valves should be installed before and after the table for easy maintenance. Customized ultrasonic thermal energy meter with protection level availableextendIP68Can still function normally when soaked in waterrunWithout being harmedSuitable for working in harsh environments.
