Description
Technical field
The utility model belongs to breaker monitoring field, a kind of primary cut-out on-Line Monitor Device based on GPRS communication.
Background technology
Along with power system is fast-developing, people are more and more higher to the requirement of power supply quality, thereby ensure that the safe operation of power equipment is more and more important.Primary cut-out is most important equipment in power system, the most extremely complex.The deterioration of breaker relates to many factors such as heat, electricity, machinery, environment, although the research to the Fault monitoring and diagnosis existing long period of breaker, but the breaker life appraisal pattern that the most still neither one is perfect, ripe.Current breaker on-line monitoring pattern uses single-chip microcomputer that class is the highest as master controller mostly, constitutes independent monitoring device.Limitation due to aspects such as the speed of single-chip microcomputer, word length, extended capabilities, there is the problems such as sampled signal is less, gather data deficiencies, record motion process shortage, analysis precision is the highest, computation model is simple, diagnosis lacks persuasion, and there is the shortcoming that man-machine interaction is friendly not, networked capabilities is poor simultaneously.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, uses TMS320F2812 digital signal processor, carries A/D conversion, more more efficient than common single-chip microcomputer fast, solve single-chip microcomputer speed, word length, the hypodynamic problem of propagation energy.
The utility model solves it and technical problem is that and take techniques below scheme to realize:
It is made up of primary cut-out, sensor assembly, signal conditioning circuit, digital signal processor, memory, display, keyboard, GPRS communication module, power supply；Described primary cut-out connects sensor assembly；Described sensor assembly connects signal conditioning circuit；Described signal conditioning circuit connects digital signal processor；Described digital signal processor connects memory, display, keyboard, GPRS communication module respectively；Described digital signal processor model uses TMS320F2812；Described power supply is powered to modules.
And, described sensor assembly includes Hall balanced type current sensor, optical displacement sensor, piezoelectric acceleration transducer and electronic current mutual inductor.
And, described power supply uses AD/DC power supply.
The utility model advantage and good effect be:
1, the utility model use TMS320F2812 digital signal processor, carry A/D conversion, it is possible to achieve the conversion to analog signal, more more efficient than common single-chip microcomputer fast, increase substantially application efficiency and reduce power consumption.
2, the utility model can reduce maintenance workload, reduce the labour intensity of person on duty, decrease the automation checked meter and record of monitoring system, person on duty can timing meter reading and record, remote measurement, remote control, remote signalling are fully achieved, thus substantially increase the automatization level of transformer station, reduce the working strength of operations staff.
Accompanying drawing explanation
Fig. 1 is that the utility model structure connects block diagram.
Detailed description of the invention
The utility model embodiment is further described by lower combination accompanying drawing:
As shown in Figure 1, a kind of primary cut-out on-Line Monitor Device based on GPRS communication described in the utility model, is made up of primary cut-out, sensor assembly, signal conditioning circuit, digital signal processor, memory, display, keyboard, GPRS communication module, power supply；Described primary cut-out connects sensor assembly；Described sensor assembly connects signal conditioning circuit；Described signal conditioning circuit connects digital signal processor；Described digital signal processor connects memory, display, keyboard, GPRS communication module respectively；Described digital signal processor model uses TMS320F2812；Described power supply is powered to modules.
Primary cut-out on-Line Monitor Device based on GPRS communication described in the utility model, with TMS320F2812 digital signal processor as core, in data processing, the electric current of breaker, magnitude of voltage are relatively big, obtain signal by sensor assembly；After respective sensor module changes signal, transfer signals in signal conditioning circuit, voltage signal is converted into the signal of applicable TMS320F2812 digital signal processor processes by signal conditioning circuit, carrying out corresponding data process, the signal processed is transferred in keyboard, display, memory；Keyboard is for modifying to the setting of parameters various in TMS320F2812 digital signal processor, to facilitate user to be controlled monitoring device as required；The parametric results of display display monitoring；By in GPRS transmission to computer, and its data are stored, print.When a certain section failure of power system, faulty component is excised from system by primary cut-out, reduces power failure range, and Accident prevention expands.
Primary cut-out on-Line Monitor Device based on GPRS communication can reduce maintenance workload, reduce the labour intensity of person on duty, decrease the automation checked meter and record of monitoring system, person on duty can timing meter reading and record, remote measurement, remote control, remote signalling are fully achieved, thus substantially increase the automatization level of transformer station, reduce the working strength of operations staff.
It is emphasized that; embodiment described in the utility model is illustrative; rather than it is determinate; therefore the utility model is not limited to the embodiment described in detailed description of the invention; every other embodiments drawn according to the technical solution of the utility model by those skilled in the art, also belong to the scope of the utility model protection.
