Vehicle-mounted terminal simulation test system applicable to detection of overload and overspeed of various types of vehicles

The invention discloses a vehicle-mounted terminal simulation test system applicable to detection of overload and overspeed of various types of vehicles. In the system, signal output terminals of a GPS simulated positioning unit, a timing unit, a vehicle type recording unit and an engine parameter acquisition unit are connected with signal input terminals of an overload and overspeed calculation processor unit by virtue of a first wireless communication transmission unit; a signal output terminal of the overload and overspeed calculation processor unit is connected with a first alarm reminding switch and is connected with a signal output terminal of an overload warning unit by virtue of a second wireless communication transmission unit; and the signal output terminal of the overload and overspeed calculation processor unit is connected with a second alarm reminding switch and is connected with a signal output terminal of an overspeed warning unit. The vehicle-mounted terminal simulation test system applicable to the detection of overload and overspeed of various types of vehicles overcomes the defects of existing static and dynamic overload monitoring and a laser radio frequency technology and a radar speed measurement system and realizes vehicle real-time online overload and overspeed precise monitoring according to different road conditions and different vehicle types.
