Description

TECHNICAL FIELD

BRIEF DESCRIPTION OF DRAWINGS

[0031] The embodiments of the present application are illustrated by way of specific examples, and other advantages and effects of the present application can be understood by those skilled in the art from the description of the specification. The present application can also be implemented or applied by other different specific embodiments, and various modifications or changes can be made to the details in the specification without departing from the spirit of the present application. It should be noted that the following examples and features in the examples can be combined with each other without conflict.

[0032] All other embodiments obtained by those skilled in the art based on the embodiments in the present application without creative labor are within the scope of protection of the present application.

[0033] In the prior art, there are the following problems: first, the vehicle transmits brake, traction, door related information and part of the vehicle other alarm information through the VOBC and TCMS interface. Since the number of information is large, the MVB bus occupancy rate has certain requirements, and too much vehicle alarm information cannot be directly provided through the TCMS-VOBC interface. Second, the vehicle alarm information signal system required by the integrated monitoring cannot be completely obtained through the TCMS-VOBC interface, so after obtaining the vehicle alarm information through the PIS channel, the alarm information is sent to the integrated monitoring system by the signal communication front-end machine. Since the PIS channel has poor stability, it is easy to have high alarm delay, loss of alarm and other situations. Third, the amount of vehicle alarm information data is huge, the communication front-end machine has high processing pressure, and the risk of downtime is high. Fourth, the expansibility is poor. If vehicle alarm display needs to be added in the future, the vehicle, signal and integrated monitoring three parties need to modify the protocol point. Fifth, when the alarm occurs, since the signal communication front-end machine is the alarm processing device of the integrated monitoring upper level, the alarm display of the integrated monitoring terminal has a certain delay compared with the signal terminal alarm display.

[0034] Therefore, in order to solve the above problems, the embodiments of the present application propose a vehicle alarm system and method. Through the signal LTE network, the data obtained by the vehicle gateway machine is more accurate and stable.
