And the unification of the format protocol of the acquisition end can ensure that the communication resources of the communication base station can be mutually called.
The communication base station configuration subsystem 200 includes a path division module 210, a route generation module 220, a requirement division module 230, a path management module 240, a base station division module 250, and a queue configuration module 260, where the path division module 210 configures a communication topology model that reflects an internet of things relationship among a collection end, a communication base station, and a processing end in the distributed collection network, the path division module 210 includes a destination determination policy and a path screening policy, the destination determination policy determines a corresponding target processing end according to data of the target processing end, the path screening policy configures path screening conditions, and the path screening policy screens a communication path that meets the path screening conditions with the collection end as a starting point and the target processing end as an ending point; the route generating module 220 configures a communication route table for each communication base station according to the communication path; the demand dividing module 230 is configured with a collection demand database, the collection demand database stores collection demand data and corresponding collection demand types, the demand dividing module 230 determines the collection demand type of a corresponding collection end according to the corresponding collection demand data, the path management module 240 is configured to generate a collection window and a collection communication load corresponding to the collection window for each communication base station directly connected with the collection end according to the collection demand type, and the collection window reflects the connection condition of the communication base station and the collection end; the base station dividing module 250 is configured to divide the communication base stations connected to the same acquisition end into the same acquisition base station group, the queue configuration module simulates a combination manner of all acquisition windows of the same acquisition base station group to generate a plurality of window combination states, and determines a pointer relationship between the window combination states according to the acquisition communication loads corresponding to the acquisition windows to generate a window combination queue; firstly, a communication base station subsystem is used for configuring a communication base station, the working principle is as follows, firstly, a path dividing module 210 determines possible paths according to a communication topological model, then, screening is carried out through a screening strategy, the topological model is pre-configured when a power grid is accessed, the types, the physical distances and the connection relations of the communication base station, a collecting end and a processing end are marked, if equipment is accessed into or accessed out of the network, the change can be directly carried out by adjusting the topological model, and the path dividing module 210 firstly determines the processing end through which information of the collecting end passes, determines the starting point and the end point of the path, and then determines all possible transmission paths according to the model. And then configuring reference transmission time for the path screening conditions, simulating the actual transmission time for transmitting standard data by each communication path by the path screening strategy, and judging that the communication path accords with the actual transmission time when the actual transmission time is lower than the reference transmission time. Whether the path meets the condition is judged through the theoretical transmission time, and the communication path which obviously does not meet the transmission time is screened out, so that all possible basic communication paths are obtained. The routing generation module 220 can configure a communication routing table for each communication base station according to the communication path, the communication routing table is different from the basic routing table, the routing table is generated corresponding to the acquisition end and the processing end, so the setting of the communication routing table can greatly save resources for repeated verification of various data, dynamic verification is replaced by a routing table verification mode, so the transmission rate between the communication base stations is greatly improved, the acquisition demand database configured by the demand division module 230 is divided according to the characteristics of the acquisition end, because each acquisition end has the default acquisition demand, such as how many times to acquire once and how many data quantity to acquire once, which is generated according to the protocol in which the processing end and the acquisition end are symmetrical, the acquisition ends are classified on the communication logic according to the types of the acquisition demands, such as the types of the acquisition ends are very various, however, if the data amount and the collection frequency are classified according to the collection logic, and only the data amount and the collection frequency are considered, the value of the load of the collection end on the collection communication side can be quantified, for example, a-Z is used as the collection end, a-B has the same characteristics such as continuous and uninterrupted communication, C-F of the first type is collected every 1S, the data amount collected once is 128 bits (second type), G is collected every 1S, the data amount collected once is 1024 bits (third type), H-K is collected every 60S, the data amount collected once is 4096 bits (fourth type), L-O is collected every 0.1S, the data amount collected once is 8 bits (fifth type), P-Z is collected once every 30S, the data amount collected once is 2048 bits (sixth type), the acquisition frequency and the acquired data amount are taken as division basis, the timely acquired data are different, the types of sensors for acquisition are different, as long as the acquisition frequency and the acquired data amount belong to the acquisition ends in the same range, the acquisition ends are uniformly divided, then all possible acquisition windows of each communication base station can be obtained through the path management module 240 according to the division result, for example, the number 1 base station is connected with five acquisition ends of A \ C \ F \ P \ Z, the acquisition ends can be quantized to have a first type, two second types and two sixth types, the combination of all possible acquisition windows of the communication base station can be exhausted, then the acquisition load of the acquisition end corresponding to each communication base station is known (related to distance, material and communication protocol), and then the communication base station with the same acquisition end can be divided into the acquisition base station groups, because the acquisition window of each communication base station in the acquisition base station group is known information, the acquisition window in the same acquisition base station group can be simulated to obtain the window combination state, because, for example, under the simulation scene that A transmits data through the base station No. 1, the data cannot be transmitted through the base station No. 2, so that all the window combination states can be obtained, for example, when only A needs to transmit, the window combination state is preferentially transmitted through the base station No. 1, but if C needs to access to transmit, the window combination state is preferentially transmitted through the base station No. 2, and the corresponding window combination state is A-1, C-2, but if F accesses to acquire, the next window combination queue is generated according to the actual load condition, and if F is connected with three communication base stations 1, 2, 3, the window combination state is calculated in advance, A/F-1, c-2 or A-1, C/F-2 or A-1, C-2, F-3, the collected communication load of three window combination states can be directly obtained by calculation, and the load value is related to the communication task which the communication base station has already taken over according to the actual physical distance, transmission protocol and the like, thus the setting can balance the communication task of each communication base station, if the calculation result is that the load of the second window combination state is minimum, the pointer of A-1 and C-2 in F access is pointed to A-1 and C/F-2, thus when F access is carried out, the No. 2 base station knows that the user wants to know the task, namely the principle of the pointer relation can be determined, therefore, the setting has very large calculation amount when the system is configured, but once configuration is completed, after the pointer relation is established, the communication efficiency is very high.
The dynamic access subsystem 300 includes a queue update module 310, an acquisition capture module 320, and an acquisition execution module 330, where the queue update module 310 acquires a current window combination state in real time and generates a corresponding trigger task to a corresponding acquisition end according to the window combination queue, and generates a first verification condition according to the trigger task when the acquisition end is in an access or an access condition, the acquisition capture module 320 is configured to capture variation information of the acquisition end, the variation information of the acquisition end reflects the access or the access condition of the acquisition end, the acquisition capture module 320 acquires a corresponding pointer relationship according to the variation information of the acquisition end and generates a second verification condition according to the pointer relationship, the acquisition execution module 330 is configured with an acquisition verification policy, and the acquisition verification policy is configured to verify whether the first verification condition generated by the acquisition end corresponds to the second verification condition generated by the communication base station, if the verification is passed, the collection executing module 330 updates the corresponding collection window according to the trigger task. The purpose of the queue updating module 310 is to obtain the current window combination state, and configure the corresponding response result at the acquisition end in advance, for example, pointers of a-1 and C-2 point to a-1 and C/F-2 when F is accessed, then F can be configured in advance, so that F knows that the corresponding communication base station is the base station No. 2, so that once F starts working, handshake can be realized immediately, steps needing to be determined are omitted, the F end does not send handshake requests to other communication base stations, for example, pointers of a-1 and C-2 when a is accessed out point to C-1, that is, C needs to be switched to the base station No. 1 for transmission, so that the data can be sent to the base station C in advance, and once the acquisition end C determines that the acquisition end a is accessed out, the base station No. 1 can be directly accessed, specifically, the trigger task comprises an access task, an exit task and a switching task, wherein the access task correspondingly connects one acquisition end with one communication base station, the exit task correspondingly disconnects one acquisition end from the communication base station, and the switching task correspondingly connects or disconnects one acquisition end with the corresponding communication base station and simultaneously switches other acquisition ends to another communication base station through a switching strategy. The acquisition execution module 330 is configured with a switching strategy, the switching strategy comprises an acquisition step and a verification step, the acquisition step is used for generating a target acquisition end, a target communication base station and a current communication base station according to a pointer relation corresponding to a switching task, the verification step comprises generating transverse verification information through the current communication base station and sending the transverse verification information to the target communication base station, the target communication base station verifies the transverse verification information and generates a switching instruction to the corresponding target acquisition end, the target acquisition end completes the switching action after receiving the switching instruction, the acquisition and the verification of the target acquisition end are realized through the two steps of acquisition and verification through the setting of the switching strategy, and then the verification is carried out through the transverse verification information, the transverse verification information is the verification information sent from the No. 1 base station to the No. 2 base station, and comprises a transverse verification information including a heartbeat synchronization data packet, the communication base station is provided with a heartbeat synchronization unit, and the heartbeat synchronization unit is used for synchronizing the time reference between the communication base stations according to the heartbeat synchronization packet. The transverse verification information comprises the latest complete waveform data. The first heartbeat synchronous data is used for synchronous calibration through transverse verification, the whole data acquisition network can perform heartbeat calibration regularly, but when data is acquired, the clock of an initiating end and a destination end which are switched is required to be consistent, so that the accuracy of waveform data can be ensured, a heartbeat data packet is sent through the transverse verification, and on the other hand, because the characteristics of the acquisition end are reserved in two communication base stations, whether the switching task belongs to or not can be verified through a group of complete waveforms, and whether the switching task corresponds or not. The acquisition capture module 320 may generate a second verification condition according to the access and exit conditions of the acquisition end, therefore, the acquisition end and the communication base station synchronously configure handshake requirements, can realize the rapid access and output of data, and after the verification is passed, because the first verification condition and the second verification condition do not correspond to each other if the data is delayed and interfered to cause data errors, the original acquisition window is kept at the moment and the data is considered to be failed in verification, if the verification is passed, the acquisition window can be updated, the dynamic access of the whole communication network is completed, the calculation cost is low, and the blocking situation is aggravated by calculating the communication load of each communication base station when the communication is congested, therefore, the dynamic balance and adjustment effects can be achieved by simplifying the calculation of a large amount of static data and feeding the data back to the communication base station in a pointer mode.
The acquisition end is provided with a local comparison unit and a corresponding transmission sub-strategy, the acquisition end compares waveform changes in real time through the local comparison unit to generate waveform change data, and the transmission sub-strategy transmits complete waveform data once every first preset time and transmits the waveform change data once every second preset time. Therefore, after the acquisition end sends data for the first time, the content of data sending can be reduced by sending variable quantity later, and the data base owned by the switched base station can realize data docking by switching the base stations through the last complete waveform data.
