In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced in other ways than those specifically described and will be readily apparent to those of ordinary skill in the art without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.
Furthermore, reference herein to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one implementation of the invention. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.
Example 1
Referring to fig. 1 to 3 and 5, a first embodiment of the present invention provides a multimode power communication method and module, which includes providing a wlan access window, so that a communication chip is connected to a plurality of distributed data monitoring terminals in a power system;
providing a communication resource channel to enable the communication chip to be connected with a control center;
and the data monitoring terminal interacts terminal service data with the control center through the communication chip.
Preferably, see fig. 1, which is a flowchart of a multimode power communication method according to an exemplary embodiment of the present application. Firstly, a wireless local area network access window is provided for data monitoring terminals which are scattered in an electric power system and take equipment ID numbers as unique marks, and support is provided for Transmission protocols such as TCP (Transmission Control Protocol), UDP (User Datagram Protocol) and the like. Further, wireless WiFi communication resources are provided for the data monitoring terminal, so that the communication chip is connected with the terminal equipment; and the communication chip can be connected with the control center through communication resource channels such as 3G/4G, and the like, so that the receiving and sending of IP service data between the local area network and the wide area network are realized, namely, the data monitoring terminal interacts with the control center through the communication chip. Of course, the use mode of the communication resource can be set by an administrator, and the communication resource can be flexibly and fully utilized.
Further, after the data monitoring terminal interacts with the management and control center through the communication chip for terminal service data, the method further includes: and adjusting the working mode of a carrier circuit of the communication chip to reduce power consumption.
Preferably, the communication module for power line meter reading has strict requirements on power consumption, and in the requirement documents of national grid electric academy, the static power consumption is not greater than 250mW and the dynamic power consumption is not greater than 1.5W for the single-phase module. In a general carrier mode, especially in an OFDM mode, static power consumption of an existing chip is generally large. If a wireless radio frequency RF circuit is added, the static power consumption requirement is difficult to meet. In the aspect of dynamic power consumption, as the carrier signal is transmitted to the power line as much as possible, the capacity of the power supply which can be provided by the electric energy meter is basically fully utilized, and if a radio frequency part is added, the power supply is easy to catch an elbow.
Further, the following measures are generally adopted to reduce the power consumption of the dual-mode module: the method comprises the following steps: waking up a carrier circuit of the communication chip at regular time to reduce the static power consumption of the communication chip; under the time-sharing working mode of the carrier circuit and the RF circuit, the carrier circuit and the wireless radio frequency circuit work in different time slots, so that the dynamic power consumption of the module is reduced; and reducing power consumption by improving a networking mode, comprising: the current communication environment is automatically detected in the subnets of the data monitoring terminal networking, a proper single-mode is adopted, and a flexible dual-mode is adopted among the subnets, so that the networking efficiency is improved while the dynamic power consumption is reduced.
Preferably, before providing the wlan access window to enable the communication chip to establish a connection with a plurality of data monitoring terminals dispersed in the power system, the method further includes: and testing the communication chip.
Preferably, the user operation interface provides an upper computer and a touch screen interface for a user, and is used for receiving a test operation instruction of the user on the novel digital micromirror chip (i.e. the communication chip) and transmitting the test operation instruction to the auxiliary controller. And the micro control unit MCU is responsible for instruction analysis, module communication and system control.
Preferably, the instruction analysis module receives an operation instruction from a user, and the MCU transmits test information transmitted from the user operation interface to the core processor. The FPGA of the core processor is responsible for carrying out function test on the communication chip and realizing the transmission of test data, namely the FPGA judges the type of a test instruction from the MCU, transmits test information to a function module corresponding to the communication chip as required and controls a driving module of the communication chip to realize the function test of the communication chip, and a video processor control module comprising the communication chip realizes the control on a video processor SiI 9616; the internal temperature testing module of the communication chip directly tests the temperature of the communication chip, and the like, so as to obtain a testing result. And the core processor transmits the result data obtained by the test back to the MCU, and the MCU transmits the result data to the operation interface for data display after receiving the returned data, so that the automatic function test of the communication chip is completed.
Fig. 2 is a schematic diagram of a 4FFT architecture according to an exemplary embodiment of the present application, and the implementation structures of the FFT frequency domain processor are mainly an iterative structure and a pipeline structure. The pipeline structure is suitable for the use scene of high-speed real-time processing. At large counts, the requirements for storage resources and computing resources are much higher than for the iterative structure. For a wideband carrier communication system, the FFT size is 1024 points, the sampling rate is only 25MHz, the reception time of a single OFDM symbol is known to be not less than 40.96us, and the data rate is not high. While the system clock of the dedicated chip can be designed to be 4 times or more higher than the sampling rate. Therefore, the iterative structure with a relatively small area can meet the processing time delay requirement of the system, and real-time processing is realized. An effective 2 butterfly parallel iteration structure, a low-delay shared memory structure can simultaneously realize external data input and read-write of a computing unit or simultaneously support result output and read-write of the computing unit. The two butterfly computing units compute in parallel. The block floating point unit is responsible for improving the dynamic range of the FFT processing at a finite word length. The control unit coordinates the FFT iterative computation process, memory scheduling, and control twiddle factor generation.
Further, providing a wireless local area network access window to enable the communication chip to establish a connection with a plurality of data monitoring terminals scattered in the power system, including: the method comprises the steps that a Central Coordinator (CCO) sends signal frames in a time-sharing mode on a wireless channel and a broadband carrier power line channel; and the data monitoring terminal STA selects and connects the OFDM wireless channel and the HPLC broadband carrier power line channel by combining parameter indexes, so that the communication chip is connected with a plurality of data monitoring terminals STA dispersed in the power system, wherein the parameter indexes comprise field intensity, signal intensity and signal-to-noise ratio.
Preferably, as shown in fig. 3, the CCO transmits a signal frame in a time-sharing manner on the HPLC + RF two channels, and the CCO and the STA integrate parameter indexes such as field strength, signal-to-noise ratio, and so on, to select an OFDM wireless channel and an HPLC broadband carrier power line channel. When the networking is not completed, in order to help the nodes which are not networked to access the network, the CCO nodes and the STA nodes transmit and forward signal frames on the HPLC + RF double channel. The CCO records the module types and access channel modes of all the network access nodes, so that a correct channel can be conveniently selected when other messages are sent subsequently, and the agent protocol PCO only records the module types and access channels of each child node of the node. After networking is completed, the beacon sending channels of the CCO and the STA are determined by the link types of the node and the direct connection sub-nodes, and are not uniformly arranged by the CCO. The network topology structure takes the CCO as the center, takes the PCO as the relay agent, comprises the PCO1 to the PCO3, and connects all the STAs, comprising the STA1 to the STA9.
Furthermore, due to excellent transmission performance on broadband wireless and a strong physical layer protocol of HPLC, the extremely low packet drop rate of wireless communication is ensured; the increased neighbor nodes shorten the routing path, reduce the system network overhead and improve the system efficiency and the communication network stability; the probability of blind spot nodes is greatly reduced, the performance and the efficiency of a communication network can be greatly improved by the multi-mode system, and the requirement of new service and new service development of the power utilization information acquisition system on the communication network is met.
Further, after the data monitoring terminal interacts with the management and control center for terminal service data through the communication chip, the method further includes: periodically performing interference signal detection, comprising: in a non-sending state, a received signal is transformed into a frequency domain of the wireless local area network through a frequency domain processor FFT, a narrow-band interference signal in a wired frequency band used by the wireless local area network is detected based on a threshold judgment mode, and an interference detection result is obtained; writing the interference detection result into an interference detection result status register, and sending an interrupt instruction to a broadband carrier power line channel (HPLC), wherein the HPLC can read the interference detection result based on the interrupt instruction and can also periodically check the interference detection result status register in a polling mode; further, the HPLC determines whether to perform carrier avoidance processing based on the interference detection result.
In conclusion, the multimode power communication method disclosed by the application realizes the function of multimode converged communication based on the power line in a breakthrough manner, and provides a most basic communication channel for the interconnection of everything by using the power line network as a main road; the access standards are unified, the defects that the traditional standards such as Bluetooth wireless, micro-power wireless and power communication are independent and cannot be intercommunicated and interconnected are overcome, and the access of various terminals in a network layer is realized.
