Description

A kind of concentrator circuit for heating system

Technical field

The utility model relates to a kind of concentrator circuit of receiving and dispatching meter information, specifically, is a kind of concentrator circuit for heating system.

Background technology

In existing heating system, usually adopt the mode that Every household has an ammeter, be provided with calorimeter and temperature-sensing valve on each service pipe, the switching by gauge tap control temperature-sensing valve realizes traffic statistics by calorimeter.

Original calorimeter is generally off-line type, charged by manual metering, manage cumbersome, development along with electronic information technology, many online charge systems of checking meter have appearred on the market, be connected with administrative center by the calorimeter of wired or wireless mode with each user, realize intelligent management.

Such system also comes with some shortcomings, because number of users is various, each user's instrument directly is connected with administrative center, if wired connection, it is cumbersome to connect up, if wireless connections, system cost is relatively more expensive again, and the maintenance of system is also relatively more difficult.

The utility model content

In order to address the above problem, the utility model proposes a kind of concentrator circuit for heating system, by adopting GPRS(General Packet Radio Service general packet radio service technology) and MBUS(Meter bus meter bus) combine, realize intelligent heating and intelligent meter data recording, simplify network topology, the intelligent degree of raising system reduces maintenance cost.

In order to achieve the above object, the technical solution adopted in the utility model is as follows:

A kind of concentrator circuit for heating system, comprise power module and microcontroller, its key is: be connected with GPRS module and mbus module at described microcontroller, microcontroller links to each other with the telemanagement center by the GPRS module, is connected with a plurality of temperature-sensing valves and calorimeter at described mbus module.

In order to realize the collection of backwater water temperature, on described microcontroller, also be connected with the return water temperature sensor.

Remarkable result of the present utility model is: circuit structure is simple, networking is convenient, utilize the MBUS meter bus that microcontroller is connected with calorimeter with the temperature-sensing valve of each user side, make a concentrator in the building can receive a plurality of users' the thermal information of using simultaneously, and then by carrying out the signal transmission between GPRS module and the telemanagement center, not only the user's heat information of collecting can be transferred to the telemanagement center, user's temperature-sensing valve control signal of can also receiving remote administrative center sending, thereby realize long-range accounting management, system intelligent height, installation and maintenance are also very convenient.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model and operation principle are described in further detail.

As shown in Figure 1, a kind of concentrator circuit for heating system, comprise power module 1 and microcontroller 2, be connected with GPRS module 3 and mbus module 4 at described microcontroller 2, microcontroller 2 links to each other with telemanagement center 5 by GPRS module 3, is connected with a plurality of temperature-sensing valves 6 and calorimeter 7 at described mbus module 4.

In order to realize the collection of backwater water temperature, on described microcontroller 2, also be connected with return water temperature sensor 8.

Specific embodiment 1:

As shown in Figure 2, calorimeter 7 is a building calorimeter, be installed on the water inlet manifold of entire building, add up the hot total amount of using in whole building, temperature-sensing valve 6 is installed on each user's the water arm of registering one's residence into, the user controls the on off state of temperature-sensing valve 6 according to being configured in indoor temperature controller 9, concentrator is collected the make-and-break time of each user's temperature-sensing valve 6 in the entire building by the MBUS bus, receive the hot total amount of using that a building calorimeter 7 adds up simultaneously, according to the make-and-break time area-method, concentrator is shared with heat each user's, will share the data upload of gained at last to telemanagement center 5, thereby realize long-range accounting management.Concentrator is connected by the MBUS bus with local instrument, passes through the GPRS module communication with telemanagement center 5, reduces the wiring trouble, reduces maintenance cost, and user's charging is shared also relatively more fair.

Specific embodiment 2:

As shown in Figure 3, calorimeter 7 and temperature-sensing valve 6 are installed on each user's the water arm of registering one's residence into, the user controls the on off state of temperature-sensing valve 6 according to being configured in indoor temperature controller 9, concentrator is collected the statistic of each user's calorimeter 7 by the MBUS bus, the user can pay heat cost in advance, limited the heating load of user's prepayment by telemanagement center 7, when a certain user's calorimeter 7 statistics gained surpass the heating load of user's prepayment with heat the time, 5 at telemanagement center sends the valve closing informations from the corresponding temperature-sensing valve 6 of this user of trend, stop this user's heat supply, concentrator not only can be collected the information of each user's calorimeter 7, can also transmit the valve control information to each user's temperature-sensing valve 6, finally reach the purpose of intelligent management.
