Abstract
The utility model relates to a kind of underground site law-enforcing recorder, comprising: main control chip, camera, memory, touch display screen, microphone, loud speaker, LED light, radio receiving transmitting module, button.Main control chip adopts ARM9 chip; Camera adopts the closed integrated camera module of technical grade OV7725; Memory is made up of dynamic random access memory and static memory, and the chip of what dynamic random access memory (SDRAM) adopted is 64MB, can be synchronous with cpu clock, and carry out dynamic data storage, random write fetching determines address date; Static memory adopts the SD card of 32G.Underground site law-enforcing recorder and 3G transmission system, server form whole work system jointly.
Description
Technical field
The utility model belongs to recorded downhole communication field, particularly a kind of underground site law-enforcing recorder.
Background technology
Existing law-enforcing recorder has mainly gathered digital vedio recording, digital photographing, intercommunication transmitter function, can carry out digitized record to field condition dynamic, static in enforcing law, is convenient to management and law enforcement use.But in down-hole, this particular location of such as colliery scene uses and just there is deficiency: instrument itself does not meet relevant national regulation in design, cause it not by the certification of coal peace, cannot use under colliery; The data transmission environments that existing instrument is complicated under can not adapting to mine, information cannot be uploaded in time; Systemic-function is single.
Summary of the invention
The utility model is for above-mentioned technical problem, and the utility model provides a kind of underground site law enforcement record, overcomes the deficiency that existing on-site law-enforcing recorder cannot use in down-hole.
The main technical schemes that the utility model adopts is: a kind of underground site law-enforcing recorder, it is characterized in that, comprising: main control chip, camera, memory, touch display screen, microphone, loud speaker, LED power indicator light, radio receiving transmitting module, button; Described camera, described memory, described touch display screen, described microphone, described loud speaker, described LED power indicator light, described radio receiving transmitting module, described button are all connected with described main control chip.
Described main control chip adopts ARM9 chip; Described camera adopts the closed integrated camera module of technical grade OV7725; Described memory is made up of dynamic random access memory and static memory, and the chip of what dynamic random access memory (SDRAM) adopted is 64MB, can be synchronous with cpu clock, and carry out dynamic data storage, random write fetching determines address date; Static memory adopts the SD card of 32G.
The utility model also adopts following attached technical scheme:
Described underground site law-enforcing recorder and 3G transmission system, server form whole work system jointly.Be positioned on central machine room, configuration wireless video gateway, storage server and streaming media server main frame, main frame installs " server admin platform software ", " SQL2000 " software, be responsible for the management to whole system, " storage server " software installed by storage server, is responsible for the audio frequency and video data of Collection and preservation safety law enforcement recorder.
Accompanying drawing explanation
Be described further below in conjunction with accompanying drawing:
Fig. 1 is underground site law-enforcing recorder front view.
Fig. 2 is underground site law-enforcing recorder rearview.
Fig. 3 is the utility model system hardware entire block diagram.
Fig. 4 is the utility model system information transmissions schematic diagram.
Embodiment
In underground site law-enforcing recorder appearance assumption diagram as shown in Figure 1 and Figure 2, antenna 1 for the connecting of down-hole 3G wireless network, button comprises menu button 2, ACK button 3, return push-button 4, and button and touch display screen 5 conbined usage, for the UI interface of field recorder under operating well.The dormancy of switch key 6 control instrument and unlatching, LED power indicator light 7 is shared out bonus, green two states, and it is not enough that red light lights indicating instrument battery electric quantity, need charge in time, and green light lights and shows that instrument electricity is sufficient, without the need to charging.Image record when camera 8 is enforced the law for down-hole and video capture.Carriage interface 9 can leave unused also can select with cameramount etc. with the use of, be convenient to long-term shooting, fuselage when being beneficial to shooting is stablized.
In the system hardware entire block diagram shown in Fig. 3, ARM9 chip connects respectively at touch display screen, LED power indicator light, button, radio receiving transmitting module, SD card, SDRAM card, microphone, OV7725 camera module, loud speaker as main control chip, realizes the various design functions of instrument.Loud speaker adds power amplifier module in being connected with ARM9 chip, for starting.
In the system information transmissions schematic diagram shown in Fig. 4, underground site recorder 4 recorded downhole by antenna transmission to information, connects with down-hole 3G wireless network 1,2,3 and communicates, then send server 5 to by 3G network, realize real-time communication over long distance.
The utility model is not limited to above embodiment, and every other execution modes drawn according to the technical solution of the utility model by those skilled in the art, drop within protection range of the present utility model equally.
