Description
Technical Field
The invention belongs to the field of power consumption information acquisition and Internet of things, and particularly relates to a meter reading network and a meter reading method for mixed loading of HPLC (high performance liquid chromatography) and micropower wireless equipment.
Background
Communication modules applied to the low-voltage power distribution network are divided into a single mode and a double mode, wherein the single mode mainly comprises two schemes of an HPLC carrier wave and a micro-power wireless RF, and the double mode mainly comprises two schemes of an HPLC/RF double-channel single network and an HPLC/RF double-protocol stack double network.
The micro-power wireless RF single-mode scheme belongs to the previous generation products, is gradually eliminated by the market and is replaced by an HPLC carrier single-mode scheme and a dual-mode scheme. The schemes need to be networked before meter reading is realized, the reading function can be realized only after the communication module is connected into the network, and the perfect compatibility of the original micropower RF equipment cannot be realized.
The HPLC carrier single-mode scheme is shown in FIG. 1, wherein H in FIG. 1 represents HPLC, a solid black line represents an HPLC network, CCO and STAs 1-6 are HPLC single-mode modules, and STAs 7-8 are standard micropower wireless RF single-mode modules. Because the HPLC carrier single-mode scheme only supports an HPLC protocol, the STA 1-STA 6 can access the network through HPLC to realize meter reading, but the STA 7-STA 8 cannot access the network and cannot realize meter reading.
The HPLC/RF dual-channel single-network scheme is shown in FIG. 2, wherein H in FIG. 2 represents HPLC, R represents micro-power wireless RF, a solid black line represents an HPLC network, a dotted line represents wireless signals, CCO and STA 1-STA 6 are HPLC/RF dual-channel dual-mode modules, and STA 7-STA 8 are standard micro-power wireless RF single-mode modules. STA1~ STA6 can all access the network through HPLC and realize meter reading, only uses micropower wireless RF signal to forward HPLC data under the condition that HPLC signal is disturbed, realizes meter reading. Due to the fact that the HPLC/RF dual-channel single-network scheme does not support a standard micro-power wireless protocol, STA 7-STA 8 cannot be connected to the network, and meter reading cannot be achieved.
The HPLC/RF dual-protocol-stack dual-network scheme is shown in FIG. 3, wherein H in FIG. 3 represents HPLC, R represents micro-power wireless, a solid black line represents an HPLC network, a dotted line represents wireless signals, CCO and STA 1-6 are HPLC/RF dual-protocol-stack dual-mode modules, and STA 7-8 are standard micro-power wireless RF single-mode modules. STA 1-STA 6 can access the network through HPLC and micro-power RF, STA 7-STA 8 can access the network through micro-power RF, and meter reading is achieved. However, when the distance between the STAs 1-6 exceeds the micro-power wireless RF communication distance, the micro-power wireless RF network is not completely constructed, so that the STAs 7-8 cannot access the network for meter reading.
It can be seen that the above-mentioned existing communication scheme has several disadvantages:
(1) the HPLC carrier single-mode scheme can only be used for networking a module with an HPLC protocol stack to realize meter reading, and for the original support of micropower RF equipment, networking meter reading cannot be carried out, the micropower equipment needs to be completely replaced, so that the construction is difficult and the cost is high;
(2) the HPLC/RF dual-channel single-network scheme cannot solve the interconnection and intercommunication with the micropower wireless RF, and the modules at two ends of communication need to be replaced, so that the field construction difficulty is high;
(3) the HPLC/RF dual-protocol stack dual-network scheme has a small micropower coverage range, so that the micropower wireless RF complete network access cannot be realized in scenes such as far distance, weak signals and the like;
(4) in order to read the scattered micropower wireless RF module data, a corresponding environment needs to be built to enable the module to be networked, and the difficulty and the cost are high.

Aiming at the defects in the prior art, the invention aims to provide a meter reading network and a meter reading method for mixed loading of an HPLC (high performance liquid chromatography) and micropower wireless equipment, and the micropower wireless technology is combined to read and write data of micropower modules which are mixed loading but are not connected to the network on the basis of establishing the HPLC network, so that low-cost fusion of a carrier and micropower is realized.
In order to achieve the technical purpose and achieve the technical effect, the invention is realized by the following technical scheme:
a meter reading network with mixed HPLC and micropower wireless equipment comprises an HPLC central coordinator, an HPLC single-mode module, an HPLC/RF dual-mode module and an RF single-mode module;
the HPLC central coordinator supports a standard single-mode HPLC protocol stack and supports the connection of II-type collector equipment types;

the RF single-mode module supports a standard single-mode micro-power RF protocol stack;
the HPLC central coordinator starts networking, the HPLC single-mode module and the HPLC/RF dual-mode module are networked through an HPLC protocol, the HPLC/RF dual-mode module is networked through the type of equipment of a type II collector, the HPLC central coordinator directly manages the networked HPLC single-mode module and the HPLC/RF dual-mode module, meanwhile, the HPLC central coordinator manages the RF single-mode module which is not networked around the HPLC/RF dual-mode module through the HPLC/RF dual-mode module, and the RF single-mode module serves as equipment for downloading the HPLC/RF dual-mode module.
Further, the HPLC central coordinator directly manages the RF single-mode module which is not networked around the HPLC/RF dual-mode module through the HPLC/RF dual-mode module; or after the HPLC central coordinator passes through at least one HPLC single-mode module, the RF single-mode module which is not networked around the HPLC/RF double-mode module is managed through the HPLC/RF double-mode module.
Further, the HPLC central coordinator simultaneously supports an HPLC transparent meter reading and concurrent meter reading.
Further, the data forwarding function between the standard HPLC protocol and the standard micropower wireless protocol of the HPLC/RF dual-mode module is specifically embodied as having a capability of performing data interaction with the standard HPLC module and the standard micropower module respectively, a capability of identifying a broadcast address meter reading and a unicast address meter reading, a capability of splitting and recombining a data frame, and a capability of data conversion between the standard HPLC protocol and the standard micropower wireless protocol, thereby realizing the intercommunication between the standard HPLC module and the standard micropower module.
Further, all the networked HPLC/RF dual-mode modules directly communicate with the HPLC central coordinator through an HPLC protocol, and are directly managed by the HPLC central coordinator; when a certain HPLC/RF dual-mode module fails to enter the network due to line interference, so that an HPLC/RF dual-mode module which does not enter the network is formed temporarily, the HPLC/RF dual-mode module which does not enter the network firstly communicates with the nearby HPLC/RF dual-mode module which enters the network through a micropower wireless protocol, then the HPLC/RF dual-mode module which enters the network communicates with the HPLC central coordinator through an HPLC protocol, and the HPLC/RF dual-mode module is indirectly managed by the HPLC central coordinator.
Further, the HPLC central coordinator is installed in a distribution room or a control room of a cell, the HPLC/RF dual-mode module is installed in a smart meter of each user in the cell, or selectively installed in smart meters of some users, the RF single-mode module is installed in a smart water meter, a smart gas meter and other meters of each user in the cell, and is installed in a smart meter in which the HPLC/RF dual-mode module is not installed, and a distance between the smart meter in which the HPLC/RF dual-mode module is installed and the smart meter in which the RF single-mode module is installed is within a communication range of a standard micropower wireless protocol.
A meter reading method by mixing HPLC and micropower wireless equipment comprises the following steps:
1) after files are synchronized, the HPLC central coordinator initiates a standard HPLC networking process, an HPLC single-mode module accesses the network through an HPLC protocol, an HPLC/RF double-mode module accesses the network through the HPLC protocol according to the equipment type of a II-type collector, and an RF single-mode module does not access the network;
2) because the RF single-mode module is used as a micropower module supporting a standard single-mode micropower RF protocol stack and cannot be connected to the network, when the RF single-mode module is read for the first time, the HPLC central coordinator adopts an HPLC protocol to initiate broadcast meter reading and sends an HPLC broadcast meter reading frame to the surrounding network;
3) after the HPLC broadcast meter reading frame reaches the HPLC/RF dual-mode module through the HPLC single-mode module, the HPLC/RF dual-mode module recombines and converts the HPLC meter reading frame into a micro-power meter reading frame, and forwards the micro-power meter reading frame on a micro-power RF public channel;
4) after receiving the micropower meter reading frame, the RF single-mode module judges whether the reading address is the own meter address or not, if not, the RF single-mode module does not respond, and if the reading address is the own meter address, the RF single-mode module sends micropower reply data to the HPLC/RF double-mode module and responds to the meter reading data;
5) after receiving the micropower reply data responded by the RF single-mode module, the HPLC/RF double-mode module recombines and converts the micropower reply data into HPLC reply data and forwards the reply to the HPLC central coordinator;
6) after receiving the HPLC reply data forwarded by the HPLC/RF dual-mode module, the HPLC central coordinator establishes a corresponding relation between the HPLC/RF dual-mode module and the RF single-mode module, and mounts the RF single-mode module to the HPLC/RF dual-mode module for management;
7) when the RF single-mode module is read again, the HPLC central coordinator directly adopts an HPLC protocol to initiate unicast meter reading according to the corresponding relation between the HPLC/RF dual-mode module and the RF single-mode module, and sends an HPLC unicast meter reading frame to the corresponding HPLC/RF dual-mode module;
8) after the HPLC unicast meter reading frame reaches the corresponding HPLC/RF dual-mode module, the corresponding HPLC/RF dual-mode module recombines and converts the HPLC unicast meter reading frame into a micropower meter reading frame and sends the micropower meter reading frame to the RF single-mode module mounted below the HPLC/RF dual-mode module;
9) after receiving the micropower meter reading frame, the RF single-mode module needing to be read sends micropower reply data to the HPLC/RF dual-mode module to which the RF single-mode module belongs;
10) and after receiving the micro-power reply data responded by the RF single-mode module mounted under the HPLC/RF dual-mode module, the HPLC/RF dual-mode module recombines and converts the micro-power reply data into HPLC reply data and forwards the response to the HPLC central coordinator.
Furthermore, some of the HPLC/RF dual-mode modules cannot be networked due to interference of a line, and thus the HPLC/RF dual-mode modules are temporarily used as non-networked HPLC/RF dual-mode modules, and when the non-networked HPLC/RF dual-mode modules are read, the HPLC central coordinator reads the non-networked HPLC/RF dual-mode modules through the adjacent HPLC/RF dual-mode module after passing through the HPLC single-mode module.
Further, when the off-network HPLC/RF dual-mode module is read for the first time, the specific steps are as follows:
1) the HPLC central coordinator adopts an HPLC protocol to initiate broadcast meter reading and sends an HPLC broadcast meter reading frame to the periphery;
2) after the HPLC broadcast meter reading frame reaches the network-connected HPLC/RF dual-mode module through the HPLC single-mode module, the HPLC/RF dual-mode module recombines and converts the HPLC meter reading frame into a micro-power meter reading frame, and forwards the micro-power meter reading frame on a micro-power RF public channel;
3) after receiving the micropower meter reading frame, the non-network-accessing HPLC/RF dual-mode module judges whether the non-network-accessing HPLC/RF dual-mode module is the own meter address or not according to the meter reading address, if not, no response is made, and if the non-network-accessing HPLC/RF dual-mode module is the own meter address, micropower reply data is sent to the nearby HPLC/RF dual-mode module to respond to the meter reading data;
4) after receiving the micropower reply data responded by the non-network-connected HPLC/RF dual-mode module, the nearby HPLC/RF dual-mode module recombines and converts the micropower reply data into HPLC reply data and forwards the reply to the HPLC central coordinator;
5) after receiving the HPLC reply data forwarded by the corresponding HPLC/RF dual-mode module, the HPLC central coordinator establishes the corresponding relationship between the HPLC/RF dual-mode module and the off-network HPLC/RF dual-mode module, and temporarily mounts the off-network HPLC/RF dual-mode module to the nearby HPLC/RF dual-mode module for management.
Further, when the off-network HPLC/RF dual-mode module is read again, the specific steps are as follows:
1) the HPLC central coordinator directly adopts an HPLC protocol to initiate unicast meter reading according to the corresponding relation between the HPLC/RF dual-mode module and the non-network-connected HPLC/RF dual-mode module, and sends an HPLC unicast meter reading frame to the corresponding HPLC/RF dual-mode module;
2) after the HPLC unicast meter reading frame reaches the corresponding HPLC/RF dual-mode module, the corresponding HPLC/RF dual-mode module recombines and converts the HPLC unicast meter reading frame into a micropower meter reading frame and sends the micropower meter reading frame to the off-network HPLC/RF dual-mode module mounted below the HPLC/RF dual-mode module;
3) after receiving the micropower meter reading frame, the non-network-connected HPLC/RF dual-mode module needing to be read sends micropower reply data to the HPLC/RF dual-mode module to which the non-network-connected HPLC/RF dual-mode module belongs;
4) and after receiving the micro-power reply data responded by the off-line HPLC/RF dual-mode module, the HPLC/RF dual-mode module recombines and converts the micro-power reply data into HPLC reply data and forwards the reply to the HPLC central coordinator.

the invention adopts the HPLC communication technology which accords with the national network technical specification standard to construct the HPLC network, and increases the micropower RF protocol stack on some HPLC single-mode modules to form an HPLC/RF dual-mode module, thereby fully playing the advantages of high HPLC transmission speed and long transmission distance on one hand, and on the other hand, utilizing the HPLC/RF dual-mode module to complete the mutual conversion of HPLC protocol data and micropower RF protocol data, thereby realizing the data interaction of the HPLC central coordinator to the RF single-mode modules at the periphery of the HPLC network.
When the method is specifically applied to upgrading and transforming community electric meters, only an electric meter at a proper position needs to be selected, and an HPLC single-mode module is upgraded and replaced by an HPLC/RF dual-mode module, so that the upgraded electric meter can not only use an HPLC network to copy electric meter data, but also copy data of intelligent water meters and gas meters in surrounding families through micro-power RF forwarding. Therefore, the scheme of the invention can be realized only by replacing part of modules on the basis of maintaining the original cell network, CCO and other configurations are not required to be replaced, the construction is simple and convenient, the cost is low, meanwhile, the problem that reading cannot be carried out due to the fact that part of electric meters cannot replace HPLC modules can be solved, the problem of mixed loading of part of RF single-mode modules in a station area is solved with the minimum cost, and the popularization of a smart power grid, the Internet of things and big data application is facilitated.

Taking a residential community as an example, a standard micropower module is arranged in an electric meter box of each user in the original residential community, meters such as an intelligent water meter and an intelligent gas meter which support a micropower protocol are also used in each user, and the meter reading function of various intelligent meters is realized by using a micropower network.
However, as the technology is updated, old equipment is gradually eliminated and upgraded in the community, and the standard micro-power wireless module in the original electric meter box of each user in the community is replaced by the standard HPLC module, which results in that the data of the original intelligent water meter and intelligent gas meter supporting the micro-power protocol of each user in the community cannot be copied.
The existing solution mainly uses two concentrators CCO supporting an HPLC protocol and a micropower protocol in a platform area at the same time, the concentrator supporting the HPLC protocol is responsible for reading the electric meter of a standard HPLC module, and the concentrator supporting the micropower protocol is responsible for reading the intelligent water meter, the intelligent gas meter and other micropower wireless meters supporting the micropower protocol, so that the cost of maintaining the dual-network is high.
