Description

The 3G intellective video monitoring device

Technical field:

The utility model relates to the monitoring field of electric control, in particular, relates to a kind of 3G intellective video monitoring device.

Background technology:

3G more is used in wireless telecommunications at present, in the wireless network.3G combined with intelligent object analysis is used in development in future trend on the mobile traffic.Taxi trade is an industry that flowability is very strong, and is more and more at the crime of taxi at present.But each city is to increase the means such as registration, GPRS location of going out of the city to the management of this respect.But still can't stop the generation of criminal offence, and main cause is that part driver vigilance is not high, seeks the convenient registration of not stopping, GPRS is to factors such as offender's fright power are not enough.Increase a vehicle-bone 3 G intellective video monitoring device, dynamically send the image in the car to center, simultaneously the position of energy positioned vehicle.If the generation crime also can be to grasp interior situation of car and offender's facial feature police's very first time, for basis for estimation is accurately made in next step action.Also can provide the most direct evidence in addition for the dispute of being unable to explain clearly between driver and the passenger.

Along with the application that 3G moves, the more and more frequent appearance in our daily life of various forms of 3G products.Yet, also do not form certain market in highly professional field of video monitoring.Its main cause is the place difference of utilization.In harmony, under the overall background of safety, field of video monitoring such as supervision of the cities, road monitoring have grown up with speed at a gallop.But these video monitorings are all installed in a fixed manner, can't satisfy the video monitoring requirement under the moving state.In public transport, railway transportation, some special industry such as taxi trade, the present product that does not also have mobile video monitor.So can't grasp the dynamic image in above-mentioned place intuitively.

The utility model content:

The purpose of this utility model is to overcome deficiency of the prior art, and a kind of 3G intellective video monitoring device is provided.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions.

A kind of 3G intellective video monitoring device, comprise CPU, 3G module, GPRS module, EM770 module, motor drive module, CMOS video sensor, the integrated ARM9 nuclear of CPU, 3G module, GPRS module, EM770 module, motor drive module, CMOS video sensor all are the external drive equipment that is based upon CPU; CPU inside comprises video compressing module, video signal sampling module, SD storage, the network port.

As a kind of improvement, described CPU is the Hi3512 chip, and the Hi3512 chip is by the external DDRAM storage of data/address bus and control bus, FALSH storage.

As further improvement, described EM770 module is carried out exchanges data by the Hi3512 chip of a PCIE interface and Hai Si.

As further improvement, described motor module adopts dc stepper motor, branch level and vertical two parts.

3G monitor video signal of the present utility model is by the 3G communication module, and form that can video is observed the field condition in the mobile traffic.Can also be applied to all trades and professions, as the type of the automatic identification vehicle used in the Intelligent traffic management systems, the stolen phenomenon of speed, museum's intellectual analysis object, a series of application such as packet loss analysis of public place.

Description of drawings:

Fig. 1 is the utility model specific embodiment main functional modules structured flowchart;

Fig. 2 is the utility model specific embodiment CPU peripheral processes circuit block diagram;

Fig. 3 is the utility model specific embodiment motor circuit schematic diagram.

Embodiment:

In conjunction with the accompanying drawings, below the utility model is further described.

The 3G intellective video monitoring device is structurally as shown in Figure 1:

1, whole system is moved under an Embedded LINUX operating system.Adopt the Hi3512 chip of Hai Si, the integrated ARM9 nuclear of this chip.Other functional module such as 3G, GPRS, SD storage, network etc. all are to be based upon the next external drive equipment of this operating system.CPU peripheral processes circuit such as Fig. 2.

2, the video compressing module of system is selected MPEG4, is H.264 waited multiple compression account form, and its compression algorithm is hardware.Reduce the resource that operates on the image compression like this, guaranteed the time of data processing.The Hi3512 chip internal that operates in Hai Si of this part is finished.

3, the EM770 module of Huawei provides 3G communication and GPRS positioning function, and the 3G communication can be selected TD CDMA and WCDMA according to the user to operator's demand.Can realize the transmission of image and voice by this module.For the terminal use, can select lan network, or the wireless network video image of watching module to provide.The size of image can be provided with video compressing module by the operating system of terminal to the 3G intellective video monitoring device according to the actual transmission speed of network and client's demand, can be set to CIF form, D1 form etc.

The EM770 module is carried out data exchange operation by the Hi3512 chip of a PCIE interface and Hai Si, and certainly, this module is also supported the USB interface operable.

4, the CMOS video sensor of 3G intellective video monitoring device is one light signal is become the device of the signal of telecommunication, its output be the mixed video signal of CVBS.

5, the mixed signal of front end is by an AD sample circuit, the analog video signal of CVBS is encoded into a digital video signal that meets the CCIR605 standard, to input to video compressing module to signal then and carry out Video processing, same audio signal is sent into an AD sample circuit after by an amplitude limit and clamp circuit, the audio signal after the sampling is directly sent in the audio-frequency module of Hi3512 and is carried out data processing.Hi3512 chip by an I2C interface and Hai Si carries out data exchange operation.

6, the network port is an output port, its objective is the audio-video signal after the compression is sent on each client by network.Procotol is supported TCP/IP stack agreement, PPPOE, Http etc.Client just can be operated and browsing video by the WEB browser on the LAN.The Hi3512 chip internal that operates in Hai Si of this part is finished.Externally as long as connect a network pulse transformer.

7, SD storage is an on-the-spot memory device.Because the restriction in space so can not do a mass memory unit, is only in particular cases just carried out the storage of short time report to the police, unusual etc.

8, Electric Machine Control.

By motor can mobile CMOS camera lens correspondence scene.Motor adopts dc stepper motor, branch level and vertical two parts.The step pitch of motor is 1.8 degree.Two-phase four is clapped.Motor circuit such as Fig. 3.

9, power supply is an important link, and the power supply in the system has 3.3V, 2.5V, 1.8V, 5V, 12V etc.And the existence of inductive load is arranged, and the PCIE bus is supported the high-speed data of 133M, the front end frequency of audio-video collection exists from the signal distributions of 100Hz ~ 10MHZ.Therefore the reasonable distribution between power supply and the signal is the key of whole design, adopts 6 layers of pcb board in design, considers EMC simultaneously.

At last, it is also to be noted that what more than enumerate only is specific embodiment of the utility model, obviously, the utility model is not limited to above examples of implementation, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection range of the present utility model.
