Embodiment 1

[0064] Please refer to figure 1 and figure 2 , this embodiment provides a method of combining multiple communication methods to build a power consumption information collection network, which solves the problem of low-voltage power consumption in the existing power consumption information collection system. The above three or more communication methods in the system cannot be arbitrarily mixed into a network; if you want to mix a network, you need to perform complex conversion problems.

[0065] The hybrid networking network in this embodiment includes at least one or more of the communication methods of micro-power wireless, power line carrier, RS485, MBUS, and infrared. Assuming that according to a specific communication network combination and equipment installation, the example network topology diagram of the mixed network that needs to be implemented currently is drawn as follows figure 2 shown.

[0066] In this embodiment, the process of realizing the above-mention...

Embodiment 2

[0089] This embodiment is further expanded on the basis of the first embodiment, and can also mark data forwarding path information in the data link layer, thereby greatly improving the efficiency of networking.

[0090] Specifically, the same part as Embodiment 1 will not be repeated, and the difference is:

[0091] In the process of "3" in the process of "2. Abstracted network model setting" in the first embodiment, the logical device addresses defined and allocated corresponding to each device also include the logical address of the forwarding tag port.

[0092] An example of logical device address allocation of a device is shown in Table 2 below.

[0093]

[0094]

[0095] The forwarding marking port is used to mark the source channel of the forwarding data frame.

[0096] Specifically, when a device contains more than two uplink channels, the forwarding mark port includes a first-level forwarding source port and a second-level forwarding source port; wherein, the fir...

Embodiment corresponding Embodiment 2

[0100] This embodiment corresponds to Embodiment 2, and provides a specific application example:

[0101] A hybrid network that includes micropower radio (RF), power line carrier (PLC), RS485, and infrared communications.

[0102] Such as figure 2 As shown, the network includes equipment: concentrator 1 with RF gateway module, energy meter 2 with RF module and RS485 interface, energy meter 3 with RF module and infrared interface, energy meter 4 with RF to PLC gateway module , multiple energy meters 5 with RS485 interface, energy meters 6 with infrared interface, energy meters 7 with PLC module and RS485 interface, and multiple energy meters 8 with PLC module.

[0103] The connection relationship of the equipment in the network is as follows: the concentrator 1 with the RF gateway module is connected to the energy meter 2, the energy meter 3 and the energy meter 4 with the RF module through the RF network; the concentrator with the RF module and the RS485 interface The elect...

Abstract

The present invention provides a method and system for constructing an electricity consumption information collection network by mixing various communication modes. The method includes: abstracting the seven-layer OSI model of the network into a three-layer communication model including The final data link layer includes the transport layer, network layer and data link layer of the OSI model; the communication addresses of each device in the network corresponding to the abstracted data link layer include logical device addresses and physical addresses; The logical device address defines and allocates logical addresses including the device itself, each functional module in the device, and each communication port used to connect to different networks, and the logical addresses in the network are not repeated. The invention supports any communication mode to flexibly build a power consumption information collection network without complex communication protocol conversion, making the networking mode simpler, more efficient, lower in cost, and higher in practicability; at the same time, the communication efficiency of the mixed networking is greatly improved.

Description

technical field [0001] The invention relates to the field of electric power communication, in particular to a method and a system for constructing a power consumption information collection network by mixing multiple communication modes. Background technique [0002] The present invention relates to communication technology, one of the key technologies of the electricity consumption information collection system. The current main communication technologies include micro-power wireless, power line carrier, RS485, MBUS, and infrared communication. At present, each of these technologies has its own advantages and disadvantages, but for the time being, none of them can cover all the requirements of the use environment through one of the communication methods. The cost of communication needs to be realized will be very high. In fact, most of the smart meter communication networks currently in operation around the world are based on a combination of multiple communication techno...
