Embodiment 1

[0054] A data communication system is given in this embodiment, please refer to figure 1 , the data communication system 1 comprises a data acquisition device 10 and a plurality of data transmission devices 20; the data acquisition device 10 forms a communication network 30 through all ports on it and all / part of the ports on the plurality of data transmission devices 20, and communicates The network 30 is a semi-mesh network topology including multiple paths, and the data requests and data responses are transmitted in one direction on the paths of the communication network 30 .

[0055] The technical contribution of the above-mentioned data communication lies in: the network topology of the communication network 30 and the data are transmitted in the way of unidirectional transmission on the path in the network topology, which can ensure that even if the communication network 30 fails It can realize the collection of data on most of the external devices.

Embodiment 2

[0059] This embodiment will describe the data acquisition device 10 in the above-mentioned embodiment 1 in detail, please refer to figure 2 , the data acquisition device 10 includes two groups of data transceiving ports and a first control device 150, wherein the two groups of data transceiving ports include a first data sending port 110, a first data receiving port 120, a second data sending port 130 and a Two data receiving ports 140; the first control device 150 is connected to the first data sending port 110 and the second data sending port 130, and is connected to the first data receiving port 120 and the second data receiving port 140, wherein the first control The device 150 includes: a data request sending module 151, which is used to simultaneously send a data request through the paths connected by the first data sending port 110 and the second data sending port 130 in the communication network; a data response receiving module 152, which is used to Simultaneously re...

Embodiment 3

[0066] This embodiment will describe the data sending device 20 in the above-mentioned embodiment 1 in detail, please refer to Figure 4 , the data sending device 20 may include two groups of data transceiving ports, namely the third data sending port 220, the third data receiving port 210, the fourth data sending port 240 and the fourth data receiving port 230, and may also include a second control device 250, which can be respectively connected to the third data receiving port 210 or / and the fourth data receiving port 230, and connected to the third data sending port 220 and / or the fourth data sending port 240, the second control device 250 Including: a data request receiving module 251, which receives a data request through the path connected to the third data receiving port 210 or the fourth data receiving port 230 in the communication network; a data response sending module 252, through the third data receiving port 230 The data sending port 220 and / or the fourth data sen...

Abstract

The invention provides a data collecting device, a data sending device and a data communication system, wherein the data communication system comprises a data collecting device and data sending devices; the data collecting device is built with total/partial ports on a plurality of data sending devices to form a communication network through all ports on the data collecting device; the communication network is of a semi-reticular network topological structure including a plurality of paths; the data request and the data response are in one-way transmission on the paths of the communication network. The realization of normal collection on data on most external equipment can be ensured under the condition that the communication network generates single-point or partial multi-point fault.

Description

technical field [0001] The invention relates to a power communication network, in particular to a data acquisition device, a data sending device and a data communication system. Background technique [0002] At present, the meter reading methods of the electric meter terminal in the power system include narrowband power line carrier meter reading, RS485 copper wire communication meter reading, wireless meter reading and broadband carrier meter reading to realize the meter reading of the meter terminal, but these meter reading methods have their own limitations. However, it cannot fully meet the requirements of various indicators for meter reading at the meter terminal. Narrowband carrier meter reading system equipment is susceptible to electromagnetic interference, and the carrier meter reading system is unstable during peak power consumption. Moreover, many companies are currently unable to solve the problem of unstable communication capabilities of the carrier meter readi...
