in an embodiment of the present invention, after the step of acquiring the first metering data received by the primary gateway and the second metering data stored by the primary gateway, the method further includes: and disconnecting the data connection of any two gateways of the at least two gateways.
In one specific embodiment, as shown in fig. 11, the metering method includes:
In this embodiment, as shown in fig. 5, after the user acquires the first metering data received by the primary gateway and the second metering data stored by the primary gateway, the data connection between any two gateways may be disconnected immediately, or the data connection between any two gateways may be disconnected after a preset time. Data connection between any two gateways is disconnected after data acquisition is finished, data transmission between the gateways is achieved only when a user acquires metering data, unnecessary data transmission between the gateways is avoided, data stored in the gateways are too much, gateway breakdown is caused, and stability of the metering device is affected.
Example eight:
in a third aspect of the present invention, a computer-readable storage medium is provided, where a charging program is stored on the computer-readable storage medium, and the charging program, when executed by a processor, implements the steps of the metering method in any one of the above embodiments.
The computer-readable storage medium provided by the present invention stores a charging program, and the charging program, when executed by the processor, implements the steps of the metering method in any of the above technical solutions, so that the present invention has all the technical effects of the charging method, and is not described herein again.
Example nine:
on the basis of any one of the above embodiments, the metering device comprises: the air conditioning system provides operation data of the system for the charging device, the input device is used for accessing internal systems of the at least two gateways to acquire the metering data stored by the gateways, and the at least two metering components are used for acquiring the metering data of the air conditioning system for charging.
Further, the at least two gateways comprise: a master gateway and a slave gateway. And the main gateway is responsible for carrying out overall statistics on all gateways in the metering device and outputting the UI interface and query data to the outside. Specifically, the master gateway receives a control instruction (the instruction includes but is not limited to gateway setting change, metering device topology, metering device inner end control and metering device activation) input by a user through an input device, and after receiving the control instruction, the master gateway issues the control instruction to a corresponding slave gateway according to the content of the control instruction and feeds back feedback information to the user through a UI (user interface) through the reply of the slave gateway; the master gateway receives a query instruction (the instruction includes but is not limited to gateway setting query, metering device topology query, metering device internal terminal information query and metering device activation state query) and issues the query instruction to a corresponding slave gateway below the master gateway, and after receiving the control instruction, the master gateway issues the query instruction to the corresponding slave gateway according to the content of the control instruction and feeds back feedback information to the user through a UI (user interface) through the reply of the slave gateway. After the slave gateway completes topology, the slave gateway performs conventional polling and charging query on the metering element connected with the slave gateway, and records the query result in the storage module. In general, the gateway is in a silent state, the master gateway does not actively interact with the slave gateway, and corresponding operation and reply are only performed when an inquiry or control instruction of the master gateway is received.
Furthermore, one gateway comprises a first data interface, a second data interface, a third data interface, a fourth data interface, a data processing and collecting module and a storage module.
The third data interface provides an operation interface for the terminal access of a user, and can be used for carrying out configuration, control, topology, query and the like related to the metering device. Furthermore, user interaction with the metering device is provided by the interface. After the interface obtains the operation of the user, the interface converts the operation into an HTTP external protocol of the metering device and issues the HTTP external protocol to a fourth data interface of the gateway.
The fourth data interface carries protocol analysis and instruction calling between any two gateways of the at least two gateways and between the gateway and the third data interface. The transmission protocol between any two gateways is an HTTP internal protocol, and the protocol between the gateways and the UI interface is an HTTP external protocol.
The second data interface is an interface of at least two gateways for processing charging, polling and other gateways to call the data processing and collecting module, and receives the call of the data processing and collecting module and the fourth data interface.
The data processing and collecting module is responsible for processing specific transaction operations such as charging, polling, setting, topology and the like, is connected with the storage module and the Modbus interface, and receives the call of the second data interface.
The storage module is used for storing information such as charging, operation records and user information.
The first data interface is used for communicating with the air conditioning system and converting a protocol of the air conditioning system.
At least two gateways in the metering device provided in the embodiments of the present invention adopt a distributed system, each gateway in the at least two gateways maintains an independent and loose organization architecture, and each gateway can independently operate (a master gateway only needs to perform topology once, that is, first communication address gateway information of other gateways except the master gateway in the at least two gateways and a second communication address of a group of metering components corresponding to each gateway are obtained, and then an off-line state can be maintained between any two gateways in the at least two gateways without affecting the charging operation), and only any two gateways in the at least two gateways need to be networked when performing query and control.
The reason why each of the at least two gateways can be independently operated is that the data processing module and the storage module of each gateway are independent metering devices, and only the tail ends of the metering pieces corresponding to the gateways are inquired and recorded. The whole metering device is not provided with a uniform storage module to collect and store data.
Primary gateway does not refer to a single gateway, and each gateway is accessible as a "primary gateway". The slave gateway is packaged into the master gateway which is communicated with the UI interface and any one of the at least two gateways through a sandwich structure of a third data interface, a fourth data interface and a second data interface.
The system disassembles the charging device and distributes the charging device on each identity equal gateway to realize the distributed layout of the system.
The metering device provided by the embodiment of the invention has the following beneficial effects:
first, the distributed layout can reduce the construction deployment of the system, the access between any two gateways of at least two gateways can be performed through the local area network, and the local area network between the buildings already exists quite universally under the current situation, and additional construction is not needed. Each gateway only needs to be connected with the corresponding metering piece and then output through the Ethernet or the wireless network.
Secondly, the distributed layout can reduce the risk of systematicness, in the traditional centralized layout, the storage module and the topological result are all centralized on one device (gateway, PC), and the stability of the metering device needs to be ensured through regular maintenance and backup, and the risk of data loss can be reduced under the condition that the metering device is damaged; and in such cases, the disruption to the data integrity of the entire metering device is substantial, if not completely, if the data is irreversibly destroyed or lost. In the metering device provided by the embodiment of the invention, because the storage module and the at least two gateways are distributed, if the metering data is unfortunately damaged, the influence is only limited on the damaged gateway, and the whole metering device cannot be affected.
Thirdly, another systematic risk reduction of the distributed layout is that the whole metering device can be operated independently in a long time offline, without relying on the scheduling of the whole metering device by the centralized master device. The whole metering device stops working under the condition that the main equipment is disconnected or shut down. In metering devices, long-term stable operation is important.
As shown in fig. 1, the metering device provided in the embodiment of the present invention is provided with at least two gateways 200 connected to an air conditioning system, and any two gateways 200 of the at least two gateways 200 are connected to each other through an ethernet or a wireless network; the metering device is connected to the air conditioning system via its own gateway 200 (bus protocols such as Modbus, CAN, bacnet).
As shown in fig. 2, each gateway 200 of the at least two gateways 200 performs external interactive communication through a third data interface 214, receives an instruction of the third data interface 214 or other gateways 200 through a fourth data interface 216, and calls and operates the data processing and collecting module through the second data interface 206.
The metering device provided by the embodiment of the invention has the following advantages:
firstly, at least two gateways adopt a distributed layout mode to realize decentralization, and a storage module and data storage operation of a metering piece are independent and offline, so that the metering device can run more stably and has simpler construction layout.
Secondly, the method of packaging the slave gateways into the master gateway through a sandwich structure of a third data interface, an external interface and a second data interface enables each slave gateway to be converted into the master gateway, enables the gateways to operate uniformly and does not add new hardware.
The charging device and the charging method provided by the embodiment of the invention reduce the hardware cost of the charging system, the structural complexity of the charging system, the construction difficulty of the charging system, the maintenance difficulty of the charging system and the use and access difficulty of the charging system.
