Description
Technical Field
The invention relates to the technical field of communication of residential electricity consumption information acquisition systems, in particular to a method for monitoring power failure events of adjacent distribution areas through an electric meter dual-mode communication module.
Background
The concentrator of the existing residential electricity information acquisition system supports a power failure event reporting function, and when a power failure event occurs in a station area to which the concentrator belongs, the concentrator reports the station area power failure event to a system master station through a built-in backup battery so that a power supply company always actively controls the power supply condition; however, in the actual operation of the residential electricity consumption information acquisition system, due to various reasons, the concentrator cannot report the power failure event to the master station in time after the power failure of the transformer area.
With the technical development and cost reduction, the electricity meter dual-mode communication module is increasingly used in the residential electricity consumption information acquisition system, and the electricity meter dual-mode communication module has a micropower wireless communication function, so that the residential electricity consumption information acquisition system actually has the communication capacity of a platform collapse area, and therefore how to deeply dig the communication capacity of the electricity meter dual-mode communication module in the platform collapse area is to realize the data acquisition and abnormal event monitoring of the platform collapse area under the condition of not increasing the hardware cost so as to improve the reliability redundancy of the residential electricity consumption information acquisition system, which is one of the directions of future development of the residential electricity consumption information acquisition system, but the residential electricity consumption information acquisition system does not have the capacity of the platform collapse area data acquisition and abnormal event monitoring at present.
Disclosure of Invention
In order to overcome the defects in the background art, the invention discloses a method for monitoring the power failure events of adjacent distribution areas through an electric meter dual-mode communication module, which actively monitors the communication conditions of the adjacent distribution areas by utilizing the wireless communication function of the electric meter dual-mode communication module; when the electricity meter dual-mode communication module does not receive the wireless communication signal of the adjacent distribution area within the set time, the electricity meter dual-mode communication module reports the power failure event of the adjacent distribution area to the concentrator wireless communication module, and therefore the power failure event monitoring function of the power failure event of the power collapse area is achieved.
In order to realize the purpose, the invention adopts the following technical scheme: a method for monitoring power failure events of adjacent areas through an ammeter dual-mode communication module is characterized in that the adjacent areas use different wireless communication frequency points and power line carriers to realize networking communication between a concentrator dual-mode communication module and the ammeter dual-mode communication module of the local area; the communication between the concentrator dual-mode communication module of each distribution area and the local electric meter dual-mode communication module is orderly carried out under the control of the concentrator dual-mode communication module, so that the problem of communication interference cannot occur in the wireless communication of all the communication modules in the same distribution area; however, because two or more concentrator dual-mode communication modules exist in adjacent areas, the problem of communication interference can be caused by wireless communication of the adjacent area communication modules, and in order to avoid the problem, different wireless communication frequency points are used in the adjacent areas; the electric meter dual-mode communication module can receive wireless signals using different communication frequency points, but in the signal processing process, the wireless signals of different communication frequency points can be filtered, so that the problem of communication interference can be avoided by using adjacent station areas of different wireless communication frequency points; when the electric meter dual-mode communication module receives a wireless communication signal of an adjacent station area for the first time, carrying out communication frequency point analysis on the received wireless communication signal, automatically jumping to a corresponding frequency point according to the analyzed communication frequency point to receive and analyze a communication message, extracting and storing codes of the adjacent station area according to the analyzed communication message, and automatically jumping back to the communication frequency point of the station area where the electric meter dual-mode communication module is located; after the adjacent station area codes are stored, the electric meter dual-mode communication module only refreshes and stores the time of receiving the wireless communication signals of the adjacent station areas when receiving the wireless communication signals of the adjacent station areas; when the adjacent distribution area is powered off, all communication modules in the adjacent distribution area stop communicating, at the moment, the ammeter dual-mode communication module cannot receive wireless communication signals of the adjacent distribution area any more, the ammeter dual-mode communication module takes the last refreshing and storing time as a starting mark and continuously detects the duration time of the wireless communication signals which cannot be received by the adjacent distribution area, and when the adjacent distribution area wireless communication signals are not received all the time within the set time, the ammeter dual-mode communication module judges that a power failure event occurs in the adjacent distribution area and reports the power failure event of the adjacent distribution area to the concentrator wireless communication module.
Further, when the electric meter dual-mode communication module does not receive the wireless communication signal of the adjacent distribution area within the set time, the electric meter dual-mode communication module automatically sends a communication message to report the power failure event of the adjacent distribution area to the concentrator wireless communication module; this mode has the advantage of controllable response time.
Further, under a normal condition, a plurality of electric meter dual-mode communication modules monitor and receive wireless communication signals of adjacent distribution areas in a distribution area, and when the plurality of electric meter dual-mode communication modules do not receive the wireless communication signals of the adjacent distribution areas within a set time, a situation that the plurality of electric meter dual-mode communication modules automatically send power failure event messages of the adjacent distribution areas within a short time may occur, so that communication interference is generated, and the concentrator dual-mode communication module cannot receive correct communication messages; in order to prevent the situation, a communication competition mechanism is arranged in the electric meter dual-mode communication module, and the communication competition mechanism determines the sequence of automatically sending the power failure event messages of adjacent distribution areas by the electric meter dual-mode communication modules;
the communication contention mechanism is defined as: a plurality of communication sub-time windows are set in the set communication time window, and the sequence of the power failure event messages of adjacent distribution areas automatically sent by each electric meter dual-mode communication module is determined by the size of a positive integer randomly generated by the electric meter dual-mode communication module; the communication contention mechanism actually operates as illustrated by the following example: the communication time window is set to be 1.0 second, 100 communication sub-time windows are arranged in 1.0 second, and each communication sub-time window is 10 milliseconds; before each electric meter dual-mode communication module automatically sends out a power failure event message of an adjacent transformer area, positive integers of 1-100 are automatically generated in the electric meter dual-mode communication module; if the positive integer automatically generated in the electric meter dual-mode communication module is 1, automatically sending a power-off event message of an adjacent transformer area within the first 10 milliseconds of a communication time window; if the positive integer automatically generated in the electric meter dual-mode communication module is 25, automatically sending a power-off event message of an adjacent transformer area within twenty-fifth 10 milliseconds of a communication time window; the communication time window takes the last refreshing and storing time of the electric meter dual-mode communication module as a starting mark, and is automatically generated after the time is set in a delayed mode; if the last refreshing and storing time of the electric meter dual-mode communication module is 10; because the generation of the communication time window has randomness, the communication time window has certain interference on the communication of the original station area.
Preferably, when the electricity meter dual-mode communication module does not receive the wireless communication signal of the adjacent station area within the set time, the electricity meter dual-mode communication module reports the power-off event of the adjacent station area to the concentrator wireless communication module through the next sent communication message; in the mode, independent adjacent power-off event messages are not adopted, and the power-off events of the adjacent power-off stations are embedded into the original communication messages of the electric meter dual-mode communication module, so that the interference to the original power-off station communication is avoided to the greatest extent.
Further, after the concentrator wireless communication module receives the power failure event of the adjacent distribution area, a broadcast instruction for prohibiting the ammeter dual-mode communication module from reporting the power failure event of the adjacent distribution area is sent out, so that the phenomenon that a plurality of ammeter dual-mode communication modules report the power failure event of the adjacent distribution area repeatedly is avoided; after the ammeter dual-mode communication module receives a broadcast instruction for prohibiting the ammeter dual-mode communication module from reporting the power failure event of the adjacent distribution area, the function of reporting the power failure event of the adjacent distribution area is closed; and when the electric meter dual-mode communication module receives the wireless communication signal of the adjacent distribution area again, the function of reporting the power failure event of the adjacent distribution area is recovered.
Due to the adoption of the technical scheme, the invention has the following beneficial effects: the invention discloses a method for monitoring a power failure event of an adjacent district through an ammeter dual-mode communication module, wherein the adjacent district uses different wireless communication frequency points and carrier communication to realize networking communication between a concentrator dual-mode communication module and the ammeter dual-mode communication module of the district; when the ammeter dual-mode communication module receives a wireless communication signal of an adjacent distribution area for the first time, the communication frequency point analysis is carried out on the received wireless communication signal, the communication frequency point is automatically jumped to a corresponding frequency point according to the analyzed communication frequency point to receive and analyze a communication message, and codes of the adjacent distribution area are extracted and stored according to the analyzed communication message; after the adjacent station area codes are stored, the electric meter dual-mode communication module only refreshes and stores the time of receiving the wireless communication signals of the adjacent station areas when receiving the wireless communication signals of the adjacent station areas; when the electricity meter dual-mode communication module does not receive the wireless communication signal of the adjacent distribution area within the set time, the electricity meter dual-mode communication module reports the power failure event of the adjacent distribution area to the concentrator wireless communication module, and therefore the power failure event monitoring function of the power failure event of the power collapse area is achieved.

When the electricity meter dual-mode communication module does not receive the wireless communication signal of the adjacent station area within 60 seconds of the set time, the electricity meter dual-mode communication module reports the power failure event of the adjacent station area to the concentrator wireless communication module through the next communication message which is sent out to answer the concentrator wireless communication module.
