With the development of modern technologies, companies are getting more and more technical opportunities to improve their services and increase the quality assurance of their provision. Increasingly popular and accessible in the market of technical solutions are mobile object monitoring systems. With their help, any transport company can guarantee the safety of the delivery of goods to its customers. They show the location of the vehicle, what it was doing stops, at what speed was the cargo carried and whether the route changed. For large cities, the ability to monitor the movement of vehicles is relevant not only for corporate purposes, but also in everyday life. With its help you can determine in which area the traffic jams.
Principle of operation
The vehicle is equipped with a tracker capable of receiving signals from the navigation system. Moreover, satellite signals and a global wireless network can be used. For this, a GLONASS, GPS or LBS module must be installed. This tracker stores in its memory all the events that occur with the car. At certain intervals, this information is sent to the main server or to the owner’s phone as an SMS message.
The main function of the system is to determine the exact location of the car with an accuracy of 2.5 meters. In addition, it allows you to view the history of the movement of vehicles. More modern systems also provide voice communication with the driver, allow you to record the audio environment around the machine, and also tell the amount of gasoline consumption and any deviations of the machine from the specified route.
Monitoring systems for mobile objects are very similar to each other, basically their trackers are identical, but there are important differences that distinguish different objects in the market. Naturally, the main difference is state ownership.
The methods of radio frequency operation are also different. So, for example, in systems of GPS-control weak protection and stable encoded access CDMA, while they are more economical and non-expensive. But the GLONASS system has a secure, reliable dedicated FDMA line, but it requires more resources.
In addition, there are differences in the location of the satellites receiving the signal. Thus, Russian satellites are unchanged when the Earth rotates. Eight satellites and three planes are used here. But in the case of American satellites, constant synchronization and correction of data are needed. Here, four satellites and six planes operate. Also there are differences in different latitudes and in the error of the signal. For example, GPS monitoring systems can distort data between two and four meters, and the GLONASS system from three to six. According to forecasts, such a gap will be reduced to ten centimeters by 2020.
The most optimal option for transport companies is the use of systems that support both navigation methods. They allow you to make the percentage of accuracy of detection of transport better and work even in difficult conditions of large cities with a high density of buildings that affect the signals from satellites.
Scope of application
Satellite monitoring of transport is relevant for courier and service providers, who need to obtain operational data on the location of couriers and cargo. Thus, it is possible to quickly track which of the employees is closest to the client’s office of the company. They are also needed by companies that have their own vehicle fleet, including taxi services, logistics companies, public transport administrators.
With the help of mobile objects monitoring systems, it is really possible to track the way, calculate the most convenient and non-expensive routes and reduce the costs for the delivery of goods. In addition, it will protect the company from unscrupulous employees who specifically wind extra miles or drain the gasoline for their needs. It should be noted that modern systems can also monitor the driver. For example, if the machine has traveled beyond a previously defined route, you can remotely muffle the engine. Also there is an option to control the ignition by tuning the car so that it will work only after sending an SMS message. GPS monitoring systems allow you to limit the speed of the car, thereby affecting the reduction in fuel consumption. Many trackers are equipped with an alarm button, which allows the driver to promptly call for help, Protecting their lives and the safety of cargo. And the availability of voice communication significantly reduces the consumption of mobile means.
