Abstract

The utility model relates to a wireless radiation-frequency (RF) temperature concentrator. In a technical scheme provided by the utility model, an uplink direction of a single-chip microcomputer is in long-distance wireless transmission with a data management center through a network module in an Ethernet manner; a downlink direction of the single-chip microcomputer is in short-distance wireless communication with a temperature measurement meter though a RF module in a wireless RF transmission manner; a CPLD (Complex Programmable Logic Device) controller is responsible for carrying out conversion control on various interface types and time-sequence control on each module, and a storage module is used for realizing periodic centralized block storage of data under the management of the single-chip microcomputer and a CPLD control unit; and a calendar management module is used for managing system time and generating periodic storage trigger signals. The wireless RF temperature concentrator disclosed by the utility model has the beneficial effects of helping operation managers to master indoor temperature conditions of users in real time so as to ensure that a heat supply company can timely learn the real-time indoor temperature values of the users without outing, and simultaneously formulating a reasonable automated operating scheme to regulate a heat source to operate and realize temperature controllability so as to reduce the energy consumption by 8-15%.

Description

Less radio-frequency temperature Centralized device

Technical field:

The utility model relates to a kind of room temperature harvester, particularly a kind of less radio-frequency temperature Centralized device.

Background technology:

Wireless room temperature collection is the new thermometric mode of rising in the last few years, mainly is used in fields such as central heating, central cooling, also can be used in industrial circle.And the continuous development of Along with computer technology, electronic technology and mechanics of communication, the automated process of industry-by-industry is accelerated gradually, to such an extent as to real-time, reliability, the quantity of information to the data collection had higher requirement in temperature acquisition.Present wireless room temperature collection mainly contains the telephone wire thermometric, GPRS mode thermometric etc., and all there is drawback separately in above-mentioned dual mode; The telephone wire temperature measuring gauge need take the phone of users home; Make troubles for user's daily life, GPRS mode thermometric need be by the GPRS network of China Mobile; Through charge on traffic, make troubles for user's follow-up maintenance.And in recent years, along with the development of wireless radio-frequency, the maturation of automatic data logging technology; Adopt wireless radio frequency mode to carry out the main flow that data transmission becomes application, radio frequency transmission need not application by free frequency range; Can conveniently in certain zone, carry out data transmission, and not have follow-up expense, once investment; Lifelong being benefited more and more receives client's favor.

Summary of the invention:

The purpose of the utility model is exactly the above-mentioned defective that exists to prior art; A kind of less radio-frequency temperature Centralized device is provided; Be used to gather the heating period user indoor temperature, and upload to Thermal Corp, for it provides temperature data accurately and timely; Assist Thermal Corp that heating network is rationally regulated, play energy-saving and cost-reducing effect.

Its technical scheme is: mainly be made up of single-chip microcomputer, CPLD controller, mixed-media network modules mixed-media, RF radio-frequency module, memory module and calendar management module, the up direction of described single-chip microcomputer is realized carrying out the long distance wireless transmission with control data corporation through mixed-media network modules mixed-media Ethernet mode; Down direction realize with the less radio-frequency transmission mode through the RF radio-frequency module and temperature measuring gauge between carry out short-distance wireless communication; Described CPLD controller is responsible for the sequential control of conversion and control and each module between the various interface type, and memory module is under the management of single-chip microcomputer and CPLD control module, and the periodicity that realizes data is concentrated and freezed to store; Calendar management module management system time and generation cycle storage trigger pip.

Above-mentioned single-chip microcomputer adopts the ATMega single-chip microcomputer.

The beneficial effect of the utility model is: this system can help operational management person to grasp the user indoor temperature situation in real time, and heating company is home-confined, can in time see the instantaneous value of remote subscriber indoor temperature; Formulate rational automatic operating scheme simultaneously, regulate the thermal source operation, realize the controllability of temperature, thereby make energy consumption reduce 8%-15%.

Description of drawings:

Accompanying drawing 1 is the structural representation of the utility model;

Accompanying drawing 2 is circuit interconnect patterns of the single-chip microcomputer of the utility model.

Embodiment:

In conjunction with accompanying drawing 1-2, the utility model is done further to describe:

The utility model mainly is made up of ATMega single-chip microcomputer, CPLD controller, mixed-media network modules mixed-media, RF radio-frequency module, memory module and calendar management module, and the up direction of described ATMega single-chip microcomputer is realized carrying out the long distance wireless transmission with control data corporation through mixed-media network modules mixed-media Ethernet mode; Down direction realize with the less radio-frequency transmission mode through the RF radio-frequency module and temperature measuring gauge (also claiming the write by hand table) between carry out short-distance wireless communication; Described CPLD controller is responsible for the sequential control of conversion and control and each module between the various interface type, and memory module is under the management of ATMega single-chip microcomputer and CPLD control module, and the periodicity that realizes data is concentrated and freezed to store; Calendar management module management system time and generation cycle storage trigger pip.

The less radio-frequency concentrator can be established the multistage routing function of deciding, and couples together the polylith temperature measuring gauge through route instruction, effectively increases the transmission range of temperature measuring gauge in the sub-district.

The utility model main application fields: the temperature monitoring in central heating field; Intelligent building, buildings temperature monitoring; Central air conditioner control and management, energy-conservation temperature control system; The temperature monitoring in museum, profile shop; Public place environment temperature monitorings such as subway; Industry Control, the monitoring of industry spot environment temperature.
