Detailed Description
The above and further features and advantages of the present invention will be apparent from the following, complete description of the invention, taken in conjunction with the accompanying drawings, wherein the described embodiments are merely some, but not all embodiments of the invention.
Referring to fig. 1 and fig. 2, a power outage warning method based on a radio frequency network according to an embodiment of the present invention includes the following steps;
s100, monitoring the power supply condition of each device in the radio frequency network in real time, and generating alarm information corresponding to power failure equipment when the power failure of the device is monitored; acquiring basic information corresponding to each adjacent node device recorded in a radio frequency module of the power down device, wherein the basic information comprises standby battery information and position information of the standby battery information;
s200, selecting a radio frequency module in corresponding node equipment to generate an optimal alarm path according to the information of the standby battery and the position information of the standby battery;
and S300, reporting the alarm information of the power failure equipment to a power failure detection system according to the optimal alarm path to perform power failure alarm.
It should be noted that the radio frequency network is formed by a plurality of devices with radio frequency modules, and data interaction can be performed between the devices by the Radio Frequency (RF) modules. And the radio frequency module can be provided with a standby battery, and the standby battery supplies power to the radio frequency module after the equipment is powered off so that the radio frequency module reports the alarm information. In this embodiment, the standby battery may be a super capacitor. For each radio frequency module, recording basic information of each node device adjacent to the radio frequency module, wherein the basic information comprises but is not limited to spare battery information, affiliated position information and signal strength information; the signal strength information is not constant, and the signal strength of each device can be periodically tested and updated, so that the accuracy of the signal strength information is ensured. The neighboring node devices include, but are not limited to, wireless access point devices capable of data interaction, small base station devices with wireless backhaul functions, and the like; the relationship between these devices may be that of an upper and lower level node.
In this embodiment, the power failure detection circuit may be used to monitor the power supply condition of each device in the radio frequency network in real time, and the power failure detection circuit may be directly implemented by using the prior art, which is not limited to this. In order to filter instantaneous faults of a user, after the power failure of the equipment is monitored, carrying out secondary monitoring on the power supply condition of the power failure equipment according to a preset time threshold value, and judging whether to recover power supply; and if the secondary monitoring result is that the equipment normally supplies power, monitoring the power supply condition of each equipment in the radio frequency network in real time. The preset time threshold may be set as appropriate, and may be 50ms to 150 ms. In this embodiment, the predetermined time threshold is 100 ms. That is, after the power failure of the device is monitored, the power supply condition of the power failure device is monitored for the second time after the device waits for 100ms, and whether the power supply is recovered or not is judged. And if the power supply of the equipment is recovered, waiting for the next power failure monitoring. And if the radio frequency module is still in a power-down state, the radio frequency module enters a generation process of an optimal alarm path. It is necessary to know that alarm information is generated every time the power failure of the device is monitored. And the alarm information generated at the last time is used as the standard. The alarm information comprises power failure time, equipment name, equipment position information and the like, so that the power failure detection system can analyze and judge the fault location, property and range according to the alarm information.
In the existing radio frequency network, when a certain device in a power grid is powered off, a transformer, a fuse section, a feeder line or a transformer substation in which the device is located may be powered off, only a communication path is directly selected, and when an upper-level routing device is also powered off, the device power failure alarm can not be reported to a power failure detection system successfully. Since each radio frequency module records the basic information of each node device adjacent to the radio frequency module, the use condition of the node device adjacent to the radio frequency module in the radio frequency network can be known only by analyzing the basic information in the radio frequency module. And then, according to the information of the standby battery and the information of the position to which the standby battery belongs, reliable reporting nodes can be effectively and quickly selected, so that the corresponding optimal alarm path is determined. The problem that the success rate is low due to the fact that the existing device directly selects a fixed communication path to report alarm information after power failure is solved.
The power failure warning method and the system based on the radio frequency network provided by the invention monitor the power supply condition of each device in the radio frequency network in real time, and report generated warning information to a power failure management system through a warning optimal path when the power failure of the device is monitored; because the optimal alarm path is determined by the backup battery information and the affiliated position information which are recorded in the radio frequency module of the power failure equipment and correspond to each adjacent node equipment, the equipment can select a reliable node to quickly determine the corresponding optimal alarm path when the power failure occurs, and the success rate of reporting power failure alarms is improved; the response time is fast, and the economic loss of customers caused by power failure is reduced.
Further, step S200 includes the following steps;
judging whether the adjacent node equipment has the standby battery equipment or not according to the standby battery information; if the adjacent node equipment has the standby battery equipment, selecting a radio frequency module of any adjacent node equipment as a reporting node to obtain a first path; if the adjacent node equipment does not have the standby battery equipment, judging whether the adjacent node equipment is under different lines according to the position information of the adjacent node equipment; if the adjacent node equipment is under different lines, selecting a radio frequency module with the strongest signal strength in the node equipment of different lines as a reporting node according to the signal strength information in the basic information to obtain a second path; if the adjacent node equipment is under the same line, selecting a radio frequency module with the strongest signal strength in the node equipment of the same line as a reporting node according to the signal strength information in the basic information to obtain a third path; and determining an optimal alarm path according to the first path, the second path and the third path according to the preset path priority.
The selection of the optimal path for the alarm can be realized in various forms. For the power failure equipment in the radio frequency network, the above steps may be to report the alarm information to other nodes or a power failure management system after being executed once. However, for the rf network, the execution is not completed until the alarm information is reported to the power outage management system. It can be understood that, after a node receives the alarm information, the node also executes the above steps to find a reporting path until reporting the alarm information to the power outage management system. The optimal alarm path is the path from the radio frequency module of the power down equipment to the reporting node of the power failure management system.
In this embodiment, the path priority is preset, and the priority of the nodes with the strongest signals of different lines and the priority of the nodes with the strongest signals of the same line are sequentially reduced. That is, the path priorities of the first path, the second path, and the third path are sequentially lowered. Therefore, when the current node reports the alarm information to the next node in the alarm optimal path, the path with high priority is selected for transmission. The generated optimal alarm path has high reliability, and the success rate of reporting alarm information is improved.
In order to determine whether the adjacent node devices are located in different lines, the determination can be performed through the affiliated substation information, the affiliated feeder line information, the affiliated fuse information and the affiliated transformer information of the affiliated location information. Specifically, judging whether the adjacent node equipment is under different lines according to the belonging position information comprises the following steps;
judging whether the adjacent node equipment is under different substations according to the substation information of the position information;
if the adjacent node equipment is under different feeder lines, judging whether the adjacent node equipment is under the different feeder lines according to the feeder line information of the position information; if the node equipment is under the same feeder line, judging whether the adjacent node equipment is under different fuses according to the fuse information of the position information; and if the node equipment is under the same fuse, judging whether the adjacent node equipment is under different transformers according to the transformer information of the position information.
The four judgments for judging whether the adjacent node equipment is in different lines are progressive relationships and are sequentially judged according to the power grid structure. And each corresponding judgment specifically comprises the steps of 1, judging whether the adjacent node equipment is under different substations according to the information of the substation to which the position information belongs, and if the adjacent node equipment is under different substations, selecting the radio frequency module with the strongest signal strength in the node equipment of different substations as a reporting node according to the signal strength information in the basic information to obtain a second path. 2. And if the adjacent node equipment is positioned in the same transformer substation, judging whether the adjacent node equipment is positioned under different feeders according to the feeder information belonging to the position information, and if the adjacent node equipment is positioned under different feeders, selecting the radio frequency module with the strongest signal strength in the node equipment of different feeders as a reporting node according to the signal strength information in the basic information to obtain a second path. 3. And if the adjacent node equipment is under the same feeder line, judging whether the adjacent node equipment is under different fuses according to the fuse information of the position information, and if the adjacent node equipment is under different fuses, selecting the radio frequency module with the strongest signal strength in the node equipment of different fuses as a report node according to the signal strength information in the basic information to obtain a second path. 4. And if the adjacent node equipment is under the same fuse, judging whether the adjacent node equipment is under different transformers according to the transformer information of the position information, and if the adjacent node equipment is under different transformers, selecting the radio frequency module with the strongest signal strength in the node equipment of different feeders as a reporting node according to the signal strength information in the basic information to obtain a second path. And if the position information (including the transformer substation, the feeder line, the fuse and the transformer) of all the adjacent nodes is the same, selecting the radio frequency module with the strongest signal strength in the adjacent node equipment as a reporting node to obtain a third path.
Compared with the first embodiment, the power failure warning method based on the radio frequency network provided by the second embodiment of the invention has the difference that the method further comprises the following steps;
and after the radio frequency module in the corresponding node equipment is selected to generate the optimal alarm path, storing the optimal alarm path into the radio frequency module of the corresponding equipment. When the equipment is powered off, the radio frequency module in the equipment can directly select the stored optimal alarm path to report the alarm information, the response time is fast, and the loss of a client is further reduced.
