Abstract
A detection and alarm device for electric power cyclic waves comprises an electric power cyclic wave circuit; electric power cyclic wave signals output by the electric power cyclic wave circuit enter a singlechip system after frequency division by a frequency dividing circuit; the input end of the singlechip system is connected with a Northern Dipper reference frequency circuit, and the output end of the singlechip system is connected with an alarm circuit. By adopting the technical scheme, precise Northern Dipper reference signals are taken as basis, the electric power cyclic wave signals collected in real time can be monitored, and when an anomaly occurs, the alarm circuit can alarm timely. As the detection and alarm device adopts precise time signals provided by a Northern Dipper satellite clock, the measurement accuracy of the cyclic waves can be effectively improved. As time signals based on a Northern Dipper satellite I navigation positioning system are adopted, the potential safety hazard caused by adoption of a GPS system is avoided, and the safety and reliability of the measurement can be ensured.
Description
Technical field
The utility model relates to a kind of electric power cycle signal that detects and unusual warning device whether occurs.
Background technology
Electric system is the important component part of the country and the regional national economic development, electric system makes, and electric power efficient, pollution-free, easy to use, that be easy to regulate and control is used widely, promoted the development of social every field, electric system scale and technical merit become one of important indicator of weighing a national economic development level.
In Operation of Electric Systems, utilize the random variation and the extraneous various interference of electric load can influence the stable of electric system, cause the fluctuation of system voltage and cycle, thereby influence the quality of electric energy, can cause collapse of voltage when serious, make electric power system accident occur.
Along with the fast development of China's Automation of Electric Systems management level, electric system has also had higher requirement to the measurement of power index, and how accurately monitoring power electric cycle signal is the problem that present electric system needs to be resolved hurrily.
Summary of the invention
The purpose of this utility model provides a kind of detection alarm device of electric power cycle signal.
For achieving the above object, the utility model is by the following technical solutions:
The utility model comprises electric power week wave circuit, enters Single Chip Microcomputer (SCM) system behind the electric power cycle signal process frequency dividing circuit frequency division of electric power week wave circuit output; The input end of described Single Chip Microcomputer (SCM) system connects Big Dipper reference frequency circuit, and its output terminal connects warning circuit.
The output terminal of described Single Chip Microcomputer (SCM) system connects remote control table by wireless communication module.
Adopt the utility model of technique scheme,, the electric power cycle signal of real-time collection is monitored, when noting abnormalities, can in time report to the police by warning circuit based on accurate Big Dipper reference signal.Because the correct time signal that the utility model adopts the big-dipper satellite clock to provide can effectively improve the cycle measuring accuracy.Employing is based on the time signal of Beidou I navigation positioning system, can avoid the potential safety hazard that adopts gps system to cause, and what guarantee to measure is safe and reliable.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises electric power week wave circuit, enters Single Chip Microcomputer (SCM) system behind the electric power cycle signal process frequency dividing circuit frequency division of electric power week wave circuit output; The input end of above-mentioned Single Chip Microcomputer (SCM) system connects Big Dipper reference frequency circuit, and its output terminal connects warning circuit.
For making things convenient for remote monitoring, the output terminal of above-mentioned Single Chip Microcomputer (SCM) system connects remote control table by wireless communication module.
Principle of work of the present utility model is: the electric power cycle signal of electric power week wave circuit output, enter Single Chip Microcomputer (SCM) system through behind the frequency division, and meanwhile, Big Dipper reference frequency circuit is also sent accurate Big Dipper reference signal into Single Chip Microcomputer (SCM) system.Single Chip Microcomputer (SCM) system is monitored the electric power cycle signal of real-time collection based on accurate Big Dipper reference signal, calculates the real-time deviation of electric power cycle, when finding that this real-time deviation is unusual, can in time report to the police by warning circuit.In addition, also real-time deviation can be sent in the remote control table by wireless communication module, make things convenient for remote personnel to monitor.
