In view of the above, the present invention provides a vehicle-mounted terminal with switchable communication modules having high cruising ability.
In order to solve the technical problems, the invention adopts the following technical scheme:
a vehicle-mounted terminal capable of switching communication modules is powered by a vehicle or an internal battery, and is characterized by comprising a control module, a first communication module and a second communication module, wherein the control module is connected with the first communication module and the second communication module, and the power consumption of the second communication module is lower than that of the first communication module;
the control module is configured to:
in a vehicle power supply state, enabling the first communication module to be in a networking state, and enabling the second communication module to be dormant;
and under the state of power supply by an internal battery, enabling the first communication module to be dormant, enabling the second communication module to be in a networking state, and enabling the second communication module to be dormant.
The vehicle-mounted terminal is provided with the two communication modules, the first communication module is in the networking state when the vehicle is powered on, and the second communication module with lower power consumption than the first communication module is switched to be in the networking state when the vehicle is powered off and is powered on by the internal battery, so that the cruising ability of the vehicle-mounted terminal is improved.

The invention is described in detail below with reference to the following figures and detailed description:
FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in fig. 1, an embodiment of the present specification provides an in-vehicle terminal capable of switching communication modules, which is powered by a vehicle or an internal battery, and includes a control module 11, a first communication module 12, a second communication module 13, a third communication module 14, a CAN module 15, an OBD interface 16, and a storage module 17.
The control module 11 is an MCU, and is connected to the first communication module 12, the second communication module 13, the third communication module 14, the CAN module 15, and the storage module 17.
In this embodiment, the control module 11 and the second communication module 13 are connected by a wake-up signal line and a communication signal line.
The power consumption of the second communication module 13 is lower than that of the first communication module 12, in this embodiment, the first communication module 12 is a 4G communication module, the second communication module 13 is an NBIOT communication module, and the two modules share the same SIM card, for example, the connection of the SIM card can be switched through a relay.
The CAN module 15 is connected to the OBD interface 16, and the control module 11 is connectable to the vehicle ECU via the CAN module 15 and the OBD interface 16.
Wherein the control module 11 is configured to:
in the power supply state by the vehicle, the first communication module 12 is put into a networking state, and the second communication module 13 is put to sleep.
In the state of being powered by the internal battery, the first communication module 12 is made to sleep, and the second communication module 13 is made to be in the networking state and made to sleep by itself.
The vehicle-mounted terminal is provided with the two communication modules, the first communication module is in the networking state when the vehicle is powered on, and the second communication module with lower power consumption than the first communication module is switched to be in the networking state when the vehicle is powered off and is powered on by the internal battery, so that the cruising ability of the vehicle-mounted terminal is improved.
Preferably, the second communication module 13 is configured to:
in the networking state, if an external instruction is received, the control module 11 is awakened, and the external instruction is sent to the control module 11.
The external command is a command sent by the vehicle external device 2, such as a command sent by a mobile terminal or a server.
The networking state of the second communication module 13 is to keep networking continuously, or to make intermittent sleep through a timer, and to keep networking during the wake-up period of the intermittent sleep.
Accordingly, the control module 11 is further configured to:
in a state powered by an internal battery:
after being awakened by the second communication module 13, the external instruction sent by the second communication module 13 is received.
Judging whether the first communication module 11 needs to be awakened or not according to an external instruction, if so, awakening the first communication module 12, meanwhile, enabling the second communication module 13 to be dormant, and if not, directly driving the peripheral equipment to complete corresponding functions, such as unlocking, alarming and the like, which do not need networking.
In such a manner, in order to monitor whether an external special instruction needs to respond after flameout, only when the second communication module 13 receives the external instruction, the control module 11 needs to be awakened, and whether switching to the state that the first communication module 11 is in the networking state is needed is judged through the external instruction, if the function corresponding to the external instruction needs to be networked, such as uploading photos, videos and the like, switching to the state that the first communication module 11 is in the networking state is needed, and if the function corresponding to the external instruction does not need to be networked, the first communication module 11 does not need to be awakened, so that the cruising ability is further improved.
