In recent years, the logistics development of China grows, the enterprise that manages logistics is on the increase, number constantly expands, the vehicle of being engaged in logistics transportation also constantly increases, and vehicle-mounted monitoring instrument is widely used, and vehicle-mounted monitoring instrument is the nucleus module of mobile unit, it locate by high-precision GPS and and other mobile unit (as Auto analyzer, fatigue driving monitor etc.) between data communication continuously, at a high speed, realize the closed loop monitoring to vehicle and personnel.But vehicle-mounted monitoring instrument function singleness in the market, the limitation of equipment application is stronger, be not easy to the expansion of follow-up function, and mostly with wired mode and sense terminals equipment connection, shortcoming data reclaim and teleprocessing function in real time, be not easy to holistic management and scheduling to vehicle and personnel, and accident is taked to counter-measure timely and effectively.
Along with making constant progress of wireless mobile telecommunication technology, the vehicle-mounted monitoring instrument that many employing wireless modes reclaim detection data continues to bring out.For example, support bluetooth or WiFi function.Bluetooth technology message transmission rate can reach 1Mbps, but communication distance is short, and network coverage nodes is limited.WiFi communication distance can reach 50 meters, and network coverage nodes is many, and message transmission rate is very high, but power consumption is also very large, generally needs external power supply.
For vehicle-mounted monitoring instrument, the data type of its collection and treatment is various and data volume is not very large, and bluetooth and WiFi have considerable message transmission rate, but corresponding power consumption is also very large, use cost is higher simultaneously, installs and uses process complexity, has caused the unnecessary wasting of resources; Meanwhile, China is on a large scale not universal WiFi still, is also restricted to a certain extent so use WiFi to carry out diagnostic data recovery.
Summary of the invention
The utility model aims to provide the vehicle-mounted monitoring instrument of the novel transmission technology of a kind of combination to address the above problem.The utility model adopts ARM CM3 series monolithic, band several functions Peripheral Interface, expectation can be contained in the cabinet of a hand size, can in haulage vehicle, bus, platform (field) and multiple industry measurement and control system, collect the user requested data such as vehicle and driver by the mode of radio communication, and by mobile communications network or reclaim storage medium in time, management and monitoring vehicle and personnel accurately.
The utility model adopts following technical scheme:
A vehicle-mounted monitoring instrument based on technology of Internet of things, comprising: MCU micro-control unit, ZigBee wireless communication module, bluetooth module, GPS locating module, data memory module, display screen, mobile communication module, camera, voice module, power module.
It is characterized in that: described described MCU micro-control unit, inner integrated ZigBee wireless communication module.
The standard that described mobile communication module adopts is GPRS/CDMA.
Described camera is placed in vehicle-mounted monitoring instrument outside, monitors at any time situation in car, and passes in real time the video data collecting back management backstage.
Described MCU micro-control unit respectively with bluetooth module, GPS locating module, data memory module, display screen, mobile communication module, camera, voice module connect.
The inner integrated multiple functional modules of vehicle-mounted monitoring instrument, not only can realize among a small circle in the communication of LAN (Local Area Network), and can realize and the communicating by letter and location of outside mobile network:
Local area network communication: vehicle-mounted monitoring instrument adopts high-grade ARM CM3 series monolithic, external bluetooth and ZigBee module for and the equipment such as Auto analyzer, fatigue driving detector carry out radio communication, reclaim in time the data that terminal sensing equipment collects.
Wan communication: external GPRS/CDMA module is for after passing the data of recovery in real time back
Platform management system, is convenient to supvr's judging promptly and accurately, decision-making.
Vehicle location: by receiving gps signal, administrative center can determine position, the shape of vehicle
State information, understands the operation distribution situation of vehicle at any time.
Image data reclaims storage: the data that collect are as driven duration, rest duration etc., warp
ZigBee or Bluetooth wireless technology return and are saved in the SD card of vehicle-mounted monitoring instrument, realize
The function of driving recording.Finally pass through USB interface, or reclaim SD card the data of record are protected
Deposit on the medium of backstage, for management software analysis.
Transmission of video: the video data of camera collection or picture are sent to control center by mobile communication module.
Voice system: driver is released news by voice system.
Show: LCD liquid crystal display (and voice announcer) can provide relevant driving information, operation indicating and schedule information etc. to driver.
The beneficial effects of the utility model are:
1, effectively utilize Internet resources, Rapid Establishment communication, Zigbee connect time
Between only need 30ms, maximum data transfer rate can reach 250Kbps, meets the requirement of the relatively little travelling data of data volume completely, has effectively utilized Internet resources; If the data volume reclaiming is large or when recovery speed is had to requirement, switch to bluetooth mode.
2, volume is little, is easy to carry, and bluetooth and Zigbee have higher integrated level, so integrated the two vehicle-mounted monitoring instrument volume is very little, facilitates user to carry.
3 install, use simply, and bluetooth and Zigbee install, use procedure is simple, have facilitated to a great extent the user of some Computer Basic Knowledge deficiencies.
4, considerable wireless communication distance: original Bluetooth communication can reach 10 meters apart from maximum, shows Zigbee module integration in diagnostic equipment, and communication distance is expanded to more than hundred meters, for user provides considerable communication distance, has expanded communication range.
