Abstract
The utility model discloses a train GPS antenna tester, comprising a standard antenna, a plug apparatus, a signal channel, a microprocessor, a temperature collection apparatus, a display apparatus and a power supply. The standard antenna and the plug apparatus are in connection with the signal channel; the temperature collection apparatus and the power supply are in connection with the microprocessor; the signal channel, the microprocessor and the display apparatus are successively in connection. The plug apparatus is arranged and a GPS antenna to be measured can be changed at any time; because the standard antenna and the plug apparatus are in connection with the signal channel, and the signal channel, the microprocessor and the display apparatus are successively in connection, whether a detected GPS antenna is qualified or not can be displayed after comparing difference of two GPS antennas. The temperature collection apparatus can detect special train GPS antennas. The train GPS antenna tester has high reliability, is easy to use, can realize higher performance with lower cost and has better test effect in a reasonable price scope.
Description
Technical field
The utility model relates to a kind of train gps antenna tester.
Background technology
Along with the rapid growth of global economy, the status of transportation by railroad in the national economic development is increasingly important.In rail traffic control system, train location is a critical link, therefore improves information prompt, reduces information error and just seem particularly important.Current train location is mainly to rely on to take GNSS (GPS (Global Position System)) location technology that GPS (GPS) is representative.Gps antenna is all housed above existing train, and when train carries out repair in shop, all needs gps antenna to overhaul, but do not have special train gps antenna checkout equipment at present.At civilian and other field, detect in the method for gps antenna, conventional have microwave dark room, signal simulator, signal forward scheme, wherein microwave dark room is with high costs, range of application is little, the cost of signal simulator is still very high, because being that signal imitation almanac data and other performance index and actual conditions may be not quite alike, lower-cost signal forwarding scheme has insertion loss because employing signal in the middle of being forwards or inserting to gain is inaccurate for antenna actual performance simultaneously.
Utility model content
The utility model is mainly to solve the existing technical matters of prior art, thereby provides a kind of reliability high, is easy to use, and with lower cost, realizes higher performance, has the train gps antenna tester of good test effect within the scope of reasonable prices.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
A train gps antenna tester, is characterized in that: comprise standard antenna, plug assembly, signalling channel, microprocessor, temperature collecting device, display device, power supply; Described standard antenna and the dress of pegging graft
Put with signalling channel and be connected, described temperature collecting device is connected with microprocessor with power supply, and described signalling channel, microprocessor, display device are connected successively.
As preferably, described signalling channel is radio-frequency (RF) circuit module.
As preferably, described microprocessor is intelligent single-chip microcomputer.
As preferably, described temperature collecting device is DS1820 temperature probe.
As preferably, described display device is LCDs.
As preferably, described power supply is built-in chargeable lithium cell group.
The beneficial effect of the utility model train gps antenna tester is: owing to being provided with a plug assembly, can change at any time the gps antenna of required measurement, because standard antenna is connected with signalling channel with plug assembly, signalling channel, microprocessor, display device is connected successively, can be after the discrepancy of two gps antennas of contrast, show the gps antenna that detects whether qualified, owing to there being a temperature collecting device, can detect special train gps antenna, there is reliability high, be easy to use, with lower cost, realize higher performance, the advantage that has good test effect within the scope of reasonable prices.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the theory diagram of a kind of train gps antenna of the utility model tester.
Fig. 2 is the DS1821 unibus schematic diagram of a kind of train gps antenna of the utility model tester.
Fig. 3 is the Fundamentals of Mono-Chip Computers figure of a kind of train gps antenna of the utility model tester.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Embodiment:
Consult shown in Fig. 1 to Fig. 3, the utility model adopts following technical scheme:
A train gps antenna tester, is characterized in that: comprise standard antenna, plug assembly, signalling channel, microprocessor, temperature collecting device, display device, power supply; Described standard antenna is connected with signalling channel with plug assembly, and described temperature collecting device is connected with microprocessor with power supply, and described signalling channel, microprocessor, display device are connected successively.
In the present embodiment, described signalling channel is radio-frequency (RF) circuit module, and described microprocessor is intelligent single-chip microcomputer, and described temperature collecting device is DS1820 temperature probe, and described display device is LCDs, and described power supply is built-in chargeable lithium cell group.
The special-purpose gps antenna checkout equipment of a train temperature collecting device, its principle is: at the integrated DS18B20 of internal system, as temperature test reference value, support DS18B20 He Yi road, a road DS1821 temperature probe simultaneously.
A kind of gps antenna detects, standard antenna signal-comparison method, its principle is: the gps antenna of the known parameters of having demarcated with the test of gps antenna detector, then test gps antenna to be measured, by relatively just obtaining the performance parameter of tested antenna to the parameter of the two.
The beneficial effect of the utility model generator data acquisition system (DAS) is: owing to being provided with a plug assembly, can change at any time the gps antenna of required measurement, because standard antenna is connected with signalling channel with plug assembly, signalling channel, microprocessor, display device is connected successively, can be after the discrepancy of two gps antennas of contrast, show the gps antenna that detects whether qualified, owing to there being a temperature collecting device, can detect special train gps antenna, having high being easy to of reliability uses, with lower cost, realize higher performance, the advantage that has good test effect within the scope of reasonable prices.
The above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
