Abstract
A GPS synchronous acquisition device of navigation mark mode is provided, which is characterized in that: the device is composed of a single chip system (4), a GPS OEM receiver (1) and a navigation mark signal modulation circuit (9). The single chip system (4) and the GPS OEM receiver (1) are connected into a whole controlling acquisition device via the navigation mark signal modulation circuit (9).
Description
Technical field
The utility model relates to the pharos remote sensing and control field, particularly a kind of synchronous acquisition device of navigation mark state multiple parameter.
Background technology
The Compensation Liability for Damage Caused by the Fault in the Administration of Aids to Navigation of China has entered into the information-based stage, and system is made up of the Control Software of control center, long-range navigation mark remote-measuring terminal platform and GIS style etc.Its medium-long range navigation mark detection and control terminal is made up of single-chip microcomputer, GPS, GPRS/GSM, electric current and voltage Acquisition Circuit etc., can finish the measurement of many navigation mark parameter currents, as battery tension, working current, the flash of light characteristic of a navigation light, the current longitude and latitude of navigation mark etc.These navigation mark remote-measuring terminals be installed in along the river or the sea the navigation channel on, realized that follow the tracks of the location and the remote measuring and controlling of many real-time parameters, the needs of pharos monitor have been satisfied with the management real work, changed traditional channel maintenance management mode, to improve Management of Aids to Navigation, alleviate worker's labour intensity, to reduce maintenance cost significant.The parameter of these navigation marks is kept in the database of control center, and the supvr can analyze the navigation mark of appointment by GIS software, understands and grasp Changing Patterns such as its longitude and latitude position, voltage, electric current, and safeguards targetedly.But when carrying out synchro control on the time in data acquisition to the navigation mark that these multiple spots distribute, when requiring with the analysis of satisfying all navigation mark state parameters of a certain moment navigation channel, present navigation mark remote-measuring terminal does not all have this synchro control mechanism on the one hand.To the most life period error of data of navigation mark data analysis time institute foundation on a certain moment navigation channel, especially consider time-delay factors such as communication on the other hand, this temporal error more can't be predicted.
Summary of the invention
The purpose of this utility model is in order to satisfy the accurate timing requirement of Compensation Liability for Damage Caused by the Fault in the Administration of Aids to Navigation department to navigation mark realization long-haul telemetry on the navigation channel, a kind of navigation mark state synchronized harvester that adopts gps signal to be provided.
For realizing that the technical scheme that the utility model purpose of design adopts is: device is made up of Single Chip Microcomputer (SCM) system, GPSOEM receiver and beacon sign modulate circuit, and by the navigation mark metering circuit Single Chip Microcomputer (SCM) system, GPSOEM receiver is connected into integral body.Two lines of serial ports transmitting-receiving of two lines of serial ports transmitting-receiving of GPS OEM receiver and single-chip microcomputer are connected, the pps pulse per second signal output of GPS OEM receiver output links to each other with an input pin with interrupt function of Single Chip Microcomputer (SCM) system, the A/D input port of Single Chip Microcomputer (SCM) system inside links to each other with the measurand navigation mark, and the navigation mark data acquisition is triggered by this pps pulse per second signal.The beacon sign modulate circuit is exactly a current-voltage conversion circuit, the operating voltage of navigation mark, working current and the characteristic of a navigation light etc. is converted to meet the voltage signal that A/D requires.
The beneficial effects of the utility model are, gps satellite signal is stable, can not drift about, and synchronisation control means is simple, cost is low, and time error is little, can realize the time synchronized to many navigation marks data acquisition on the navigation channel easily.
Description of drawings
Fig. 1 is the utility model structural representation.
In Fig. 1, (1) is GPS OEM receiver, (2) be two lines of serial ports transmitting-receiving, (3) be pps pulse per second signal in the GPS OEM receiver (1), (4) are Single Chip Microcomputer (SCM) system, and (5) are the inner serial port resources of Single Chip Microcomputer (SCM) system, (6) be the input pin that has interrupt function in the Single Chip Microcomputer (SCM) system, (7) be the A/D input port of Single Chip Microcomputer (SCM) system inside, (8) are the measurand navigation marks, and (9) are the beacon sign modulate circuits.Serial ports transmitting-receiving two lines (2) of GPS OEM receiver (1) and (5) two lines of inside serial port resource of Single Chip Microcomputer (SCM) system (4) link to each other, the pulse per second (PPS) output (3) of GPS OEM receiver (1) and the input pin with interrupt function (6) of Single Chip Microcomputer (SCM) system (4) link to each other, the A/D resource output port (7) of Single Chip Microcomputer (SCM) system (4) links to each other with beacon sign modulate circuit (9), and beacon sign modulate circuit (9) links to each other with measurand navigation mark (8).
Embodiment
For the ease of the design is further understood, now the synchro control harvester of navigation mark data acquisition is done specific implementation process and describe in conjunction with Fig. 1.
As gathering navigation mark data synchronization signal, realize that the time synchronized of many navigation marks data acquisition on the navigation channel is controlled with the pps pulse per second signal (3) of GPS OEM receiver (1) output.Error second of pps pulse per second signal (3) output is 1 microsecond in the GPS OEM receiver (1), and with the time series of this signal as the navigation mark data acquisition, then the time error of per second sampling is certainly less than 1 microsecond.This synchronous disposal route strictness in the collection of synchronization to the navigation mark data, the data that are transmitted back to control center have also comprised the correct time mark of GPS OEM receiver output, thereby have realized the time strict synchronism of many navigation marks data.
