CN201928356U - Dome camera control system - Google Patents

Abstract

The utility model discloses a dome camera control system. A control panel consists of a keyboard with a ball-head joystick, an identity code memory chip, a master control chip, a display chip, a temperature chip, a clock chip, a motor-driving chip and a position-limit chip. A monitor is provided with a resistance touch liquid crystal display screen or a capacitance touch liquid crystal display screen. The dome camera control system changes the conventional mechanical control mode and can reflect required information directly without requirements of human memorization. The system can display menu prompts when confronted with faults, maintenance and questions. If a touch liquid crystal display screen is adopted, operators can carry out man-machine conversation directly on the screen, thereby greatly reducing operation tensity and reducing risks of work at height in maintenance and debugging processes.

Description

A kind of spherical camera control system

Technical field

The utility model relates to the photography apparatus, particularly a kind of spherical camera control system.

Background technology

Present most of spherical camera does not have menu to show, spherical camera mainly by spherical joystick and wiring realizes and main frame between get in touch, in general be connected with main frame by the RS485 connection, and address code is set with the DIP switch, such operation is very not directly perceived, monitoring for multimachine position spherical camera, the monitor staff must remember that address code seeks corresponding key position at piano type DIP switch, people's sight line must be switched back and forth at different visual fields, be easy to generate visual fatigue, too much DIP switch address sign indicating number, make that operating personnel are difficult to remember, if careless be provided with the error or the wrong line can cause the ball machine not run well, serious words can be damaged ball machine control circuit.

In addition for install, debug, staff's repetition ascend operation when safeguarding, exist the risk of high-altitude construction.

Summary of the invention

The utility model purpose is to propose a kind of spherical camera control system at the existing technical problem of existing spherical camera operating environment, all operations is arranged on its original display screen shows with menu-style, accomplishes human-computer dialogue.

The technical scheme that the utility model solves is: a kind of spherical camera control system comprises control desk; Spherical camera; Monitor; RS485 communication line assembly; Video line,

Described control desk is made of the spacing chip of keyboard, address code storage chip IC1 (W78E65), main control chip IC2 (W78E65), OSD display chip IC4 (MAX7456), chip temperature (DS18B20), clock chip (DS1302), 24C256 motor drive ic IC3 and 2PIN DIP switch (SW1) of dribbling shape joystick, wherein 4 of IC1 11 and 13 pin that are connected IC2 with 5 pin; 24,25,26,27,28 pin of IC1 connect 16,17,18,19,20 pin of DIP switch (SW1); 29,30,31,36 pin connect 12,13,14,15 pin of DIP switch (SW1), and 17,18 pin of IC2 connect 5 and 6 pin of IC3, and 28,29,30,31 pin of IC2 connect 8,9,10,11 pin of IC4;

Described monitor, its display screen are resistive touch liquid crystal display screen or capacitance touch liquid crystal display screen.

The beneficial effects of the utility model are: the MAX7456 character overlap chip is come display menu, the RS485 protocol signal is converted to the serial ports level (TTL) of single-chip microcomputer by the level conversion device, program control with single-chip microcomputer, realize that spherical camera shows relevant information and address code setting on the OSD menu, make operation become directly perceived, the risk of having avoided debugging, repeating when safeguarding to ascend a height and construct has been simplified debugging routine.

Embodiment

Spherical camera 6 reads the address code by hardware setting (DIP switch SW 1) after starting, if revised spherical camera 6 address codes in menu, address code is set is new address code and be presented on the screen.Operation to spherical camera 6 is the address according to this new address code all afterwards, if address code is not waited for newer command and judged whether address code is correct spherical camera 6.The correct spherical camera 6 of address code is just according to order operation corresponding operating.Spherical camera 6 is restarted the back address code and is initialized as the hardware address sign indicating number.

Spherical camera 6 power on back IC1 receive spherical camera 6 addresses that are provided with by toggle switch SW1 then IC1 send to main control chip IC2(W78E65 by pin 4,5).IC2 sends to OSD display chip IC4(MAX7456 to spherical camera 6 addresses of changing with the spherical camera 6 address .IC2 in its built-in menu program of this address initialization by pin 28,29,30 and 31 in menu), IC4 outputs to external connection display equipment to spherical camera 6 addresses that needs show by pin 26 through inter-process.

By pin 17 and 18 spherical camera 6 addresses are sent to IC3, and spherical camera 6 addresses that receive are stored in the IC3 chip.

Controlling level is rotated; P0.1 controls vertical rotation; P2.4, P2.5, P2.6, P2.7 are used for communicating by letter with OSD display chip MAX7456; Write displaying contents, initial explicit address, show end address and display mode etc.

, TXD is used for communicating by letter with spherical camera 6, read spherical camera 6 information and send order to spherical camera 6; UP DOWN is vertical limit signal.0 degree position of control upright position and 90 degree positions.

, P3.6 is used for communicates by letter with storage chip; Preserve and read information, it is spacing that P2.2 is used for level; The datum mark of The Cloud Terrace horizontal level, P1.3 are used to read the temperature information of chip temperature DS18B20; P1.0, P1.1, P1.2 are used for and the communicating by letter of the following piece DS1302 of clock, can modification time, and time for reading.

Compare with traditional spheroidal video camera 6 control system, the utility model has changed the traditional mechanical control model, make that operating personnel only need to operate on a display screen interface, during for numerous spherical camera 6 team controls, can be directly on computer keyboard 9 input need the title of address spherical camera 6 (as floor; Street name etc.), system can directly reflect information needed, need not the manpower memory, as run into fault, maintenance, query, but system's display menu prompting, as adopting touch LCD screen, operating personnel then can directly realize human-computer dialogue on screen, thereby alleviate manipulation strength greatly, also avoid safeguarding and the risk of ascend operation when debugging.
