Monitoring (Control) vehicle — actively used in enterprises with the operation of vehicles in order to prevent improper use or theft,
Project GPS — Global Positioning System — is a satellite navigation system owned by the United States, the project took place in 1973.
System GLONASS (GLOballroom ATvigatsionnaya Withputnikovaya WithSystem) — Russiansatellite navigation system, component of a sluggish competition GPS, acceptance into operation took place in 1993, but because of the then insufficient satellites in orbit has been temporarily suspended (for the moment only works 23 working satellites because of the recent failure of the 24 satellites and then the spare satellite in the same orbit), the system GLONASS currently has full coverage of the globe because of the delay of the signal (up to 3 hours).
The components of the system satellite tracking of vehicles
Satellite monitoring system includes three main elements:
1. GPS | GLONASS The controller is directly mounted on the trucks.
2. Storage server that receives data from the controller through GSMi a Wi-Fi signal.
3. A client program downloads the data from the server and allows the user to handle it.
GPS | GLONASS controller consists of a specialized GPS | GLONASS device comprising a receiver GPS | GLONASS antenna for remote communication with the database server (GSM or Wi-Fi). As a server, the data is possible using a personal computer containing the specified server software, while the computer with the server software should be open 24/7, to continuously receive data. The client software does not require a permanent job, but only for download from time to time the actual data from the server and process them.
The history of the development of systems for monitoring vehicles
Over time, since technological progress and the emergence of the high demand vehicle monitoring systems keep pace with the times.
Originally controllers GPS | GLONASS not have online mode data and the data received in the database dispatcher terminal only after the arrival of the machine with the route and the manual download to the control computer with the device this option controllers have enough big drawback is that each unit had to withdraw from the transport and download the data manually.
Then came the instruments with online sending data through the transfer of GSM signals. This type of controller required for a remote data server to collect information sent to the client in the future which could download the data and process, ie the production of customer data considerably simplified, and also now monitoring of transport was conducted online.
But also, a number of disadvantages are: 1) The subscription fee for the service GSM operator 2) Potential loss of signal or no coverage in areas beyond the reach of the operator GSM.
Over time, there was a solution to the problems associated with the work out of the reach of mobile operators, with the advent of the controllers can operate by transmitting data via Wi-Fi access points, this type of controller is badly needed in the remote corners of our country. Data is transmitted in transport passage points with Wi-Fi access and enters the server which, in turn, the customer can carry out their preparation for further processing.
