Embodiment
See also Fig. 1, it is the overall applicability structural representation of the utility model household camera card, the pluggable household camera of the proprietary definition of a kind of employing card, comprise MCU, multichannel is selected switch, first video buffer, audio video synchronization testing circuit and camera and The Cloud Terrace telecommunication circuit, described multichannel is selected switch, the audio video synchronization testing circuit is connected with MCU respectively with camera and The Cloud Terrace telecommunication circuit, multichannel selects switch by the external four-way CCD camera of first video buffer, also comprise a gateway and main circuit board interface, MCU is connected to this gateway and main circuit board interface, and multichannel also is connected to this gateway and main circuit board interface after selecting switch through second video buffer.Described household camera card is connected with the main circuit board interface by gateway with external gateway main circuit board.
As Fig. 2, be that the multichannel of the utility model household camera card is selected switch circuit figure, because the video channel of this household camera card and gateway main circuit board has only one the tunnel, so synchronization has only a camera job.For reaching the function of four road video switchs, increase described multichannel and selected switch, select the output of a road in the middle of four tunnel by the level of control S0 and S1, used a slice 74HC4051D, multichannel is selected switch, and it is the logical block that 1 tunnel output is selected in 8 tunnel inputs, under the 10V power supply, bandwidth is 40Mhz, satisfies bandwidth requirement.
As Fig. 3, be the video buffer circuit diagram of the utility model household camera card.The main effect of described video buffer is that the video to front end carries out buffered, video to prime can not produce any influence on the one hand, be that relative prime video is a high impedance load, the video to prime carries out clamp on the other hand, the vision signal of outputting standard.
As Fig. 4, be the MCU circuit diagram of the utility model household camera card, described MCU single-chip microcomputer, major function is that it is made up of a MCU single-chip microcomputer, a reset circuit and a crystal oscillator in the video transmission of coordinating and control a plurality of terminal rooms.
As Fig. 5, the camera of the utility model household camera card and The Cloud Terrace telecommunication circuit schematic diagram.It adopts the MAX485 communicating circuit, this chip for driving can control circuit reiving/transmitting state, if the front end camera has only this integrated circuit board control, the output of drive circuit can keep transmit status always, if the front end camera is with other system and connect controller, the output of drive circuit can only remain on accepting state, and inquiring is oneself to have in the time of sending permission, begins to send data.
As Fig. 6, it is the audio video synchronization testing circuit schematic diagram of the utility model household camera card, the LM1881 chip that described audio video synchronization testing circuit adopts is the Video Sync Separator Chip at TV signal, it can directly carry out separated in synchronization to TV signal, obtains required video signal exactly.
As Fig. 7, the gateway of the utility model household camera card and the circuit diagram of main circuit board interface, described gateway and main circuit board interface are made up of the interface of one 64 pin, realize that by this interface whole household camera card is connected with external plugging of gateway main circuit, its each pin is defined as follows shown in the table:
| Pin arrangements | Pin name | The |
| 1 | TX | Send data to |
| 2 | RX | Receive the data on the |
| 5 | INT3 | The interrupt signal of four-way |
| 15 | SEL0 | Chip selection signal 0 |
| 16 | SEL1 | |
| 17 | SEL2 | |
| 18 | SEL3 | |
| 19 | STROBE | Chip selection signal enables (low level is effective) |
| 24 | VI2 | Four-way CCD camera card |
| 20、33、34、41、42、53、54、60 | GND | |
| 21、22、48 | +5V | + 5V |
| 55、56 | +12V | + 12V DC power supply |
| 59 | RESERT | The reset signal of four-way CCD camera card |
Its operation principle is as follows:
(1) when host computer does not have sheet to select integrated circuit board, the four-way CCD camera card is in accepting state; When host computer (main frame) need be with four-way CCD camera card intercommunication, STROBE, SEL0, SEL1, SEL2, these chip selection signals of SEL3 were to be set to corresponding state; When data sent host computer (main frame) to, integrated circuit board sent interrupt signal and informs host computer (main frame); The function that realization is switched four-way CCD camera;
(2) carry out PTZ, FI when control when host computer needs the camera of band cloud platform, the order of transmission through MCU " parsing " after, use the video equipment control protocol of standard to send to the camera of band cloud platform by serial ports again.Because RS485 maximum transmission distance standard value is 4000 feet, this 50 feet of maximum transmission distance standard than RS232 is much bigger, and therefore, it generally all is to adopt RS485 that the camera of band cloud platform is controlled.The camera of band cloud platform receives only order generally speaking, and no return data if any, also is the communication pattern that adopts RS422, so this integrated circuit board is as long as the TX transmitting terminal signal of UART at once, need not the RX receiving terminal.Because baud rate is supported four kinds, so, must there be two toggle switch that required baud rate is set.
The utility model adopts the pin of proprietary definition, makes pluggable intelligent monitoring card, and function for monitoring as long as insert this control card and insert camera equipment on the basis of original system, can be realized intelligent monitoring function if desired; Otherwise if do not need this function, as long as pull out this control card and talk back equipment, the changeable of functional module is saved cost for producing, for the client brings material benefit; Can also the PTZ of multichannel camera control and FI controlled function be realized in integrated circuit board by the four-way CCD camera card, make more stable treated data of system, improved the autgmentability of system, reduced the cycle of repair and upgrade.
