Abstract
A GPS clock of blank pipe system is provided, which comprises a 485 serial receiving chip and a RS232 serial receiving chip which receive GPS clock signal respectively; the output signals of the two serial receiving chips is drawn to a singlechip by interconverting; the singlechip controls a LED to display UTC time or Beijing time digitally; the front board of a cabinet is arranged with a UTS or Beijing time display selector button connected with the singlechip and a time display window. The utility model is compatible with two different data of civil aviation and military aviation and can display UTC time or Beijing time respectively. After receiving serial alert data from an industrial computer, the singlechip can drive a warner to give out alarm; meanwhile, an auto clock connected with the singlechip is provided, which can output real time clock signal to the singlechip in case of having no GPS clock. The utility model has widespread application value in blank pipe system and other fields.
Description
Technical field
The utility model relates to time display, and particularly the clock of GPS (GPS) timing system used of air traffic control system is made the field.
Background technology
GPS (global satellite product positioning system) clock signal is the time reference in the whole world, the gps time display that uses in the air traffic control field lacks the compatibility to civil aviaton and two kinds of different pieces of informations of army's boat, and display panel is provided with the UTC time showing, therefore, its use occasion has certain limitation.
The utility model content
Task of the present utility model provides a kind of compatible civil aviaton, army's boat data, can carry out the Beijing time demonstration, can carry out the air traffic control system gps clock of UTC time showing again.
This novel task is achieved in that a kind of air traffic control system gps clock, comprise casing, single-chip microcomputer, LED nixie display, also have the 485 serial ports receiving chips and the RS232 serial ports receiving chip that receive the gps clock signal respectively, the output signal of the two can be changed mutually and cause described single-chip microcomputer; Also be provided with on the casing front panel and be connected UTC/ Beijing time with single-chip microcomputer and show selector button; The casing front panel is provided with can be according to selecting to show UTC or the time showing window of Beijing time.
Also has the alarm that receives the Single-chip Controlling signal, sends chimes of doom.
Also have with single-chip microcomputer be connected, the circuit of retention time real-time clock so that when no gps clock, export the signal of real-time clock to single-chip microcomputer.
The circuit of above-mentioned retention time real-time clock is a constant-temperature crystal oscillator, and its oscillation frequency is 12MH, and precision is 0.5ppm.
This gps clock is that the LED under Single-chip Controlling shows, it adopts 485 serial ports receiving chips and RS232 serial ports receiving chip, the two can change (as through a change-over switch K conversion) mutually, can receive the data of two kinds of different-formats of the civil aviaton that sends here by the GPS receiver or army boat respectively, under Single-chip Controlling, realize the static state or the dynamic time of LED charactron are shown; In addition, the selector button on the casing front panel can be made Beijing time demonstration or UTC time showing respectively.
This is novel to have following characteristics:
1, to satisfy aviation air traffic control system demand, compatible civil aviaton, army's boat data can be carried out the UTC time showing, can carry out the Beijing time demonstration again.
2, have the Realtime Alerts function, receive the warning serial data that Industrial Control Computer is sent here, after single-chip microcomputer receives the serial alert data, drive alarm and send chimes of doom by RS232.
3, have automatic clock (being the circuit of retention time real-time clock), can be when no gps clock, export the signal of real-time clock to single-chip microcomputer, show again.
4, since nixie display pass through transmission line after 485 interfaces carry out conversion the serial ports of signal input single-chip microcomputer, the longest 800m that reaches of transmission line can satisfy the on-the-spot needs of air traffic control system.
This gps clock can be accepted the data of civil aviaton, two kinds of different-formats of army's boat, can easily realize the demonstration of UTC time or Beijing time, thereby its scope of application is bigger, function is more complete, satisfies the request for utilization in blank pipe field and also is with a wide range of applications in its field.
Description of drawings
Fig. 1 is this novel embodiment electric theory diagram of (static state of LED number shows);
Fig. 2 is the electric theory diagram of this novel another embodiment (the dynamic demonstration of LED number);
Fig. 3～Fig. 6 is the front view of the front panel of this Novel GPS clock series.
Embodiment
Fig. 1 illustrates, the gps clock signal inserts 485 serial ports receiving chips and RS232 serial ports receiving chip respectively, the output of the two (through a change-over switch K) can cause single-chip microcomputer with changing mutually, single-chip microcomputer is through code translator, latch driver, control static LED nixie display, with static state show the moon, day, week, the time, minute, second.What adopt among Fig. 1 is hardware decoding, also can adopt convenient, flexible, can show special font, radix point is handled software decoding easily.UTC/ Beijing time shows that selector button is connected with single-chip microcomputer, selects by bouncing pilotage, shows UTC time or Beijing time, and promptly nixie display is sent into signal the serial ports of single-chip microcomputer, the longest 800m that reaches of transmission line by transmission line after 485 interfaces carry out conversion.Also can receive the gps time Data Receiving by the RS232 serial ports.UTC/ Beijing selects may command to show UTC or Beijing time, determine as calculated to show, and calculate number of weeks according to year, month, day, by code translator produce latch signal the corresponding moon, day, the time, the minute, second code deposits in separately the register, show behind driver being transformed into seven-segment code by chip, more than operation is finished under Single Chip Microcomputer (SCM) program control.
Fig. 2 is a dynamic time display circuit block diagram, and display is sent into signal the serial ports of single-chip microcomputer, the longest 800m that reaches of transmission line by transmission line after 485 interfaces carry out conversion.Another single-chip microcomputer 2 is accepted the number of weeks sent here by single-chip microcomputer 1, produces a series of corresponding number of weeks by the control program of single-chip microcomputer 2, and raw column data shows corresponding Chinese-character digital code by light emitting array.Year, month, day, hour, min, second dynamically demonstration of realization under the control of refurbishing procedure.Its process is the number that is shown by single-chip microcomputer 1 output, export the address that this number shows again, in latch driver, code translator are during in unit, refresh number and address respectively, like this year, month, day, hour, min, second just can on nixie display, show dynamically.
Automatically clock (being the circuit of retention time real-time clock) is connected with single-chip microcomputer, and its signal inputs to single-chip microcomputer, so that when no gps clock, exports the signal of real-time clock to single-chip microcomputer.Automatically clock is when outage, and standby power supply is powered to automatic clock, thereby will be from automatic clock acquisition time data at that time when powering again.
Automatically clock can adopt local crystal oscillator (to produce the Beijing time signal), local crystal oscillator output signal to single-chip microcomputer.Local crystal oscillator is selected constant-temperature crystal oscillator for use, and its oscillation frequency is 12MHZ, and precision is 0.5ppm.
Single-chip microcomputer also is connected with the alarm (not shown), and after single-chip microcomputer received the warning serial data that Industrial Control Computer sends here by RS232, the control alarm sent chimes of doom.
Above-mentioned UTC/ Beijing time shows that selector button is arranged on the casing front panel, and the LED nixie display is placed on the time showing window of casing front panel.UTC time showing pilot lamp and Beijing time show that pilot lamp all is located on the casing front panel.
