In the taxi industry, automotive electronic GPS navigation and positioning systems mainly have the following applications: GPS navigation and positioning systems are used in the automotive field, which we call automotive GPS positioning systems:
1. Vehicle scheduling, unified management and scheduling of all taxis in the control center, reduce empty driving, and improve the effective use of vehicles and road resources;
Second, anti-theft and anti-robbing, real-time query of vehicle location through positioning, stolen vehicles can be retrieved in time to avoid causing major economic losses, and the general GPS locator system is integrated with an alarm function, the driver can immediately call the company or 110 in an emergency Call the police and seek help immediately;
3. Data collection. The management platform collects the positioning information of all vehicles, processes and publishes them to relevant units or platforms in order to achieve the purpose of information sharing and cooperation;
4. Video surveillance. By installing a camera and uploading photos of passengers in the car to the server, you can ensure that you can quickly and timely find relevant personnel in the event of an accident or crime, and ensure the safety of the driver's personal property.
The GPS positioning system is a practical system that combines high technology with actual needs, so in practical applications, how effective is it? Is it convenient to use, or does it really increase the profit? Let us take a closer look at it.
Many people report that although it is possible to call a taxi by phone, the actual implementation is quite disappointing. Although there is a customer service to answer and provide services, most of the time there is no affirmative answer, after the passengers have waited for a long time I would rather go to find a taxi by myself, and most people have not heard that you can call a taxi by phone, or get used to go out and find it by yourself. Drivers also have difficulties. There is no shortage of passengers during peak hours, and it is more efficient to find guests through their own experience when there is little traffic.
As for anti-theft and anti-robbing, if the dispatch center cannot report to the police in time, it will not be a good preventive and remedial measure. Although the fuel and power cutoff function can prevent the vehicle from being driven away, the driver trapped in the same car is still in danger Among them, not to mention the serious traffic accidents that may be caused by sudden fuel and power cuts while driving.
To sum up, if GPS positioning system can really bring benefits to taxi companies and drivers, it is also necessary for service providers and companies to cooperate better and propose a truly win-win solution.
Li-ion Battery With SMBUS refers to the battery datas can be collect through equipments based on SMBUS data communication, it usually applied to the military grade battery which need higher safety level protection .but as these battery have SMBUS inside ,it also should meet these requirements as :
1.The rated voltage is high (the operating voltage of the unit is 3.7v or 3.2v), which is about equal to the series voltage of three nickel-cadmium or nickel-hydrogen charging batteries, so as to form the battery power supply group
2.The self-discharge rate is very low, which is one of
the most prominent advantages of the battery. At present, it can reach less
than 1% per month, less than 1/20 of the nickel hydrogen battery.
