Vehicle-mounted TBOX SOS key state detection device, system and method

Abstract

The invention provides a vehicle-mounted TBOXSOS key state detection device, system and method. The detection device comprises a microprocessor MCU, a remote communication module and a double-wire key detection circuit module. The MCU is respectively connected with the remote communication module and the double-wire key detection circuit module; the double-wire key detection circuit module is connected with a detected vehicle-mounted key; the MCU module is used for managing and controlling each functional module in the equipment, acquiring the key state ADC, judging the key state, and uploading abnormal information to a vehicle network platform and / or notifying an emergency rescue center through the remote communication module when the key state is abnormal; the remote communication module is used for realizing information interaction between the vehicle-mounted TBOX equipment and the vehicle networking platform server and / or communicating with an emergency rescue center through a telephone; and the double-line key detection circuit module is used for detecting the state of the key. Therefore, various abnormal key states can be detected, and the safety risk is reduced.

Description

technical field [0001] The present application relates to the technical field of Internet of Vehicles, in particular, to a vehicle-mounted TBOX SOS key state detection device, system and method. Background technique [0002] Since a large number of cars are equipped with TBOX with ECALL function, when the vehicle encounters an emergency, such as a rollover or collision in a deserted suburb or on a highway, the ECALL function can automatically trigger an emergency call. Or press the SOS button artificially to trigger an emergency call; if the button is short-circuited, dropped, stuck, etc. at this time, it may not be able to automatically or manually trigger the emergency call, resulting in the owner being unable to seek help in time. Delayed timing may lead to relatively serious casualties. Contents of the invention [0003] In view of this, the present application provides a vehicle-mounted TBOX SOS button state detection device, system and method, so as to at least achi...
