The overall design of the system: 1. The design principle of GPS safety monitoring system for logistics vehicles follows the following principles when designing the technical implementation scheme of the system: All for safety, Safety reminders include speeding reminder, dangerous road reminder and fatigue driving reminder. Safety monitoring includes speeding monitoring, overload image monitoring, fatigue driving warning, shouting warning and so on. Common standard functions: remote settings, monitoring, telephone calls, dispatching, alarm and so on. 2. The design of system economy system reduces the cost as much as possible and pursues the maximization of performance-price ratio under the condition of optimum performance. The software system is developed independently, which facilitates long-term cooperation and ensures the economy of the software system. GPS customized functions for logistics vehicles: 1. Vehicle positioning * instant positioning. Continuous recording of vehicle position defaults to 30 seconds. Recorded parameters include: speed, position, driving direction, alarm status. Tracking and comparing multi-car colleagues in new windows. 2. Mileage Statistics * GPS Mileage Statistics: Vehicle-borne GPS calculates mileage once a second. 3. Vehicle anti-theft * Vehicle positioning: After finding the vehicle lost, the vehicle can be positioned and the vehicle can be retrieved. Anti-theft device linkage: docking with original car anti-theft device, alarming synchronously with anti-theft device and platform. 4. Long-distance lockout * Long-distance extinguishing: It can control the vehicle extinguishing remotely, and use recovery vehicle with anti-theft function. Remote control: Credit vehicles can remotely control the loss of main functions of vehicles and urge payment. 5. Trajectory playback Location trajectory time interval can be adjusted 5-65535 seconds, default 30 seconds Trajectory can be saved for more than 12 months, if necessary, can be backed up by CD. Line playback: It can adjust playback speed, pause and other operations. It is often used to check the historical route, gas station and toll information of vehicles. 6. Freight dispatch Regional vehicle inspection: Search for nearby vehicles according to the source of goods. Information Sharing: Freight information can be sent to the Chinese display screen of vehicles working nearby. 7. Safety alarm Overspeed alarm: Vehicles exceed the required speed alarm, in order to ensure the safety of cargo transport. Power off alarm: GPS is removed after the power supply alarm to the platform in time. Regional alarm: Alarm when driving out of restricted driving area platform. System Composition: The monitoring center is the "nerve center" of the whole system, which centralizes monitoring, dispatching, receiving/dealing with alarms, image processing functions and other information services, and coordinates and manages the software and hardware of the whole system. Vehicle terminal function is responsible for data transmission between vehicle terminal and monitoring center. This part is mainly GPRS/CDMA public data network. As long as GSM or CDMA can cover, the system can run steadily. Common functions include the following: vehicle positioning: fixed time continuous positioning, speed measurement, motion direction, etc. Monitoring and alarming: speeding, fatigue driving, unloading, accidental long-term parking, etc. Oil-cut and power-off: Used for remote lockout in emergencies. Text scheduling: External dispatching screen, handle, etc. Voice broadcasting: External voice broadcaster with speaker. Custom alarm: Users can connect various detection switches according to their needs and support triggering camera to take photos. Monitor and alarm function: > Overspeed alarm: upload alarm beyond the speed threshold set by the company, with report forms. Enclosure alarm: vehicles exceed the prescribed range of traffic alarm; emergency alarm: when the owner is in danger, the alarm switch should be pressed to alarm, the center must intervene manually in order to cancel. Custom alarm: Support 1-2 way self-defined alarm, such as open door alarm, the vehicle should connect the door switch. Power off alarm: Battery removal or equipment power off alarm must be removed by manual intervention. Vehicle Location Tracking and Multi-vehicle Simultaneous Tracking: Immediate Location: Name Location, Location of Current Time of Vehicle; Final Location: Update Location of Vehicle Uploaded Actively; Vehicle Tracking: Continuous Location of Vehicle and Drawing Track on Map. Multi-vehicle tracking: Tracking and comparing multi-car colleagues in a new window. Support four kinds of maps, standard Mapinfor maps, direct display of vehicle location signs on Google Map maps, and Satellite Topographic maps, plane annotated maps and mixed annotated maps. Track playback Track data preservation: Track data is stored on the server, independent of the locomotive; Track data download: download from the server to the client computer. Track playback: playback of vehicle trajectory for a period of time; playback pause: pause during playback, used to observe the driving process of a section in detail. All kinds of alarms are introduced: Emergency alarm: when the owner is in danger, the alarm switch is pressed to alarm, and the center must intervene manually to cancel. Overspeed alarm: Upload alarm beyond the speed threshold set by the company, with sound and light prompts. Power off alarm: Battery removal or equipment power off alarm must be removed by manual intervention. Custom alarm: Support 1-2 way self-defined alarm, if unloading is alarm, the vehicle should be connected with the detection switch. Enclosure alarm: vehicles exceed the prescribed range of traffic alarm; line alarm: vehicles exceed the pre-planned line alarm. Overtime parking: parking beyond the specified time. Idle alarm: vehicle idle speed exceeds the specified time. Voice broadcasting, dispatching and answering module * Voice broadcasting function can make the monitoring center group voice information to achieve the effect of shouting broadcasting. The dispatching function is that the monitoring center can issue written notifications of text information. Drivers can respond to built-in information with a display screen, which can be seen in the center. Vehicle remote settings
