Among the figure, 1. voltage sample module, the 2.DSP chip, 3.U coils module for reading and writing, 4. definite value Compare Logic module, 5. dead electricity control logic module, 6. power module, 7. nonvolatile memory, 8. wireless communication module.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
The structure of the utility model railway low-voltage distribution fault alarm automated wireless transmitting supervisory device, as shown in Figure 1, comprise the voltage sample module 1 that connects successively, dsp chip 2, USB flash disk module for reading and writing 3 and nonvolatile memory 7, voltage sample module 1 also successively with definite value Compare Logic module 4, dead electricity control logic module 5 connects, also be connected with wireless communication module 8 on the USB flash disk module for reading and writing 3, wireless communication module 8 is connected with dead electricity control logic module 5, power module 6 respectively with voltage sample module 1, dsp chip 2, USB flash disk module for reading and writing 3, definite value Compare Logic module 4, dead electricity control logic module 5, nonvolatile memory 7, wireless communication module 8 connects powers.Wherein,
USB flash disk module for reading and writing 3 is used for the parameter tuning of device, reads the related data of storage simultaneously by USB interface.
Definite value Compare Logic module 4 is used for the comparison of sampled data and preset data.
Dead electricity control logic module 5 is used to judge situations such as whether circuit short circuit occurs, open circuit.
The course of work of the utility model railway low-voltage distribution fault alarm automated wireless transmitting supervisory device is: input two-way three-phase voltage signal is given voltage sample module 1, voltage sample module 1 filters harmonic wave and undesired signal, definite value Compare Logic module 4 compares the data and the preset data of sampling, if voltage exceeds preset value, then report to the police by wireless communication module 8, be sent to information center and maintenance personal's on duty mobile phone with the GSM note, simultaneously this incident is write USB flash disk module for reading and writing 3 by nonvolatile memory 7, convenience later record and analysis to data; If do not exceed preset value, then whether judge at interval the current sampled value of this storage to write USB flash disk module for reading and writing 3 by nonvolatile memory 7 if should store then by the data storage of adjusting.When circuit short circuit appears, when situation such as opening circuit, voltage can occur unusually, this moment, sampled data judged that through dead electricity control logic module 5 back sends off signal by wireless communication module 8 to information center, so that eliminating line fault is in time dispatched by information center, finish the storage of information simultaneously.Under the device busy state, detect its USB interface automatically and whether be inserted with USB flash disk equipment, then light run indicator and finish read-write operation automatically USB flash disk if having.At first read the parameter tuning file on the USB flash disk and finish adjusting and upgrading of contents such as setting-up time and date, voltage upper lower limit value, the phone number that sends message pick-up, periodically sending information, device Working mode set, data storage interval by USB flash disk module for reading and writing 3, adjust till the parameter tuning value of file changes up to detecting USB flash disk next time; Stored record information in will installing then writes in the file of USB flash disk appointment, and device was closed the operation to USB flash disk automatically after operation was finished, and signal lamp extinguishes.The data that USB flash disk reads can obtain monitored power supply distribution ruuning situation and power supply power quality analysis by the dedicated analysis software analysis.Device is installed in the panel box, and its power supply is taken from low-voltage distribution one phase power supply, gets the operating voltage of each module of auto levelizer through rectification and voltage division.Whole device must just can send warning message in the telecommunication signal coverage, otherwise data can only be recorded in and use the USB flash disk dump in the device.
