A PCI bus data acquisition card and a serial port are arranged on the computer. The pulse per second signal of GPS satellite receiver is connected with the digit triggering channel of PCI bus data acquisition card. The standard time signal of GPS satellite is connected with the serial port of computer. The measurand is connected with the analog input channel of PCI bus data acquisition card. The utility model is particularly fit for the industry with the distributed work of petroleum, power, traffic, water conservancy, water supply, gas, etc. as well as with the requirement of remote precise timing control and measurement.
Description
Technical field:
The utility model relates to a kind of multiple spot synchronous data collection device, relates in particular to the multiple spot synchronous data collection device that adopts gps satellite signal to trigger in the long-distance distribution TT﹠C system.
Background technology:
GPS (Global Position System GPS) satellite provides in global range regularly and positioning function, and GPS user obtains spatial positional information, synchronous time mark and standard time by the gps satellite receiver.When the long-distance distribution TT﹠C system needs many places strict time synchronous acquisition data, use the clock of the synchronous time mark calibration data acquisition device of gps satellite receiver usually, with the data acquisition unit clock control sampling time.The process need acknowledge(ment) signal of clock alignment, deal with data are operated hardware then, the unavoidable life period error of this process, and especially under Windows operating system, this error more can't be predicted.
Summary of the invention:
The purpose of this utility model is exactly in order to satisfy the job scheduling of water conservancy, electric power, traffic system, the analyzing and positioning of electric network fault, the leakage monitoring of oil transportation, water supply, gas piping, the early warning distributed operation industry of sudden disaster such as floods, earthquake provides a kind of multiple spot synchronous data collection device that adopts gps satellite signal to trigger for the requirement of remote measurement and control accurate timing.
The purpose of this utility model is achieved in that it comprises computing machine, gps satellite receiver, measurand, computing machine is provided with the pci bus data collecting card, gps satellite receiver pps pulse per second signal links to each other with pci bus data collecting card numeral trigger port, the time reference signal and the serial ports of computers of gps satellite join, and measurand links to each other with pci bus data collecting card analog input channel.
Compared to existing technology, it is easy to the utlity model has the method for manipulating, and cost is low, time error is little, and gps satellite signal can not wear out, and can not drift about, be not subject to external interference, can realize easily that the many places that are distributed in different regions carry out advantages such as strict time data in synchronization collection.
Description of drawings:
Fig. 1 is the utility model structural representation
Embodiment: the utility model is described in detail in detail below in conjunction with accompanying drawing and embodiment, it comprises computing machine 4, gps satellite receiver 1, measurand 9, computing machine 4 is provided with pci bus data collecting card 7, serial ports 6, the pps pulse per second signal 3 of gps satellite receiver 1 links to each other with pci bus data collecting card 7 on the computing machine 4, the standard time mark 2 and the serial ports 6 of gps satellite join, measurand 9 links to each other with the pci bus data collecting card 7 of computing machine 4 by signal wire 8, and computing machine 4 is provided with data output interface 5.
Principle of work of the present utility model is, by the pci bus data collecting card 7 on the pps pulse per second signal 3 triggering computing machines 4 of gps satellite receiver 1, and the time reference signal 2 of additional gps satellite, realize being distributed in many places strict time synchronous data collection of different regions.
Pci bus data collecting card 7 needs numeral and triggers function, begins a data acquisition after promptly receiving a pulse signal 3.For example use the E series data capture card of America NI company, it is receiving that the mistiming that begins to sample behind the pulse signal 3 is far below the microsecond level.The error of the pps pulse per second signal 3 of gps satellite receiver 1 is generally 1 microsecond.When therefore doing the signal source of trigger data acquisition with the pps pulse per second signal 3 of gps satellite receiver 1, the time error that each sampling position per second begins to sample will be less than 1 microsecond.
Each signal of measurand 9 is connected respectively to each sampling channel of pci bus data collecting card 7, and the pps pulse per second signal 3 of gps satellite receiver 1 is connected to the digital trigger port of pci bus data collecting card 7.Driver programming to pci bus data collecting card 7 is set to whenever receive that a rising edge of digital pulse signal 3 begins a data acquisition.Receive the standard time information of gps satellite simultaneously by the serial ports 6 of computing machine 4, as the sampling time label.
This method has guaranteed that each different location strictness carries out data acquisition at synchronization, and adds the correct time mark for the data of gathering.Having solved remote measuring and controlling system adopts modes such as telephone wire, LAN (Local Area Network) and wireless public network to transmit the problem that data can not guarantee the data transmission real-time, the data of each point collection through different routes, not equidistantly realize strict time synchronized according to the time mark of data after being transferred to control command centre, obtain the precise time information of different location sampling.
For example the oil pipeline leakage monitoring system needs each monitoring point strict synchronism to carry out data acquisition, and the sampled data in the identical moment arrives the host computer of doing analyzing and positioning simultaneously with the location leakage point.But because present the limiting this and almost can not accomplish of network technology level.In order to remedy the data transmission period difference that network environment causes, sampled data can be added that the time mark of sampling instant is transferred to host computer, carry out leakage point when location again with sampled data by sampling time " alignment ".But the clock of computing machine 4 exists time error, although this error generally has only 0.3～0.5 second every day, but is unallowable for the leakage monitoring location.Adopt this device to address this is that, and gps satellite signal can not wear out, can not drift about, not be subject to external interference, realize easily technically, on cost, can accept.
