receiving and displaying second information from a cloud monitoring platform.
In the above solution, acquiring the first information of the automobile may include:
acquiring a load of the automobile through a deformation sensor;
acquiring a tire pressure of a wheel of the automobile through a pressure sensor; and
acquiring a temperature of a wheel hub of the automobile through a temperature sensor.
In the above solution, acquiring the load of the automobile through the deformation sensor may include:

The present disclosure will be further described in detail below in conjunction with the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure, but not to limit the present disclosure.
This embodiment provides a method for monitoring an automobile based on a satellite. The method can be performed by a vehicle-mounted computer or an independent computer connected to a monitoring sensor of an automobile. As shown in
At block 101: acquiring first information of the automobile.
In this embodiment, acquiring the first information of the automobile includes:
acquiring a load of the automobile through a deformation sensor;
acquiring a tire pressure of a wheel of the automobile through a pressure sensor; and
acquiring a temperature of a wheel hub of the automobile through a temperature sensor.
That is to say, in this embodiment, the first information includes a load of the automobile, a tire pressure of a wheel of the automobile, and a temperature of a wheel hub of the automobile.
In this embodiment, acquiring the load of the automobile through the deformation sensor includes:
acquiring deformation data of the wheel hub of the automobile after being loaded through the deformation sensor; and
acquiring the load of the automobile by processing the deformation data through a preset algorithm.
Here, both the tire pressure of the wheel and the temperature of the wheel hub are acquired directly through sensors, while the load of the automobile is acquired by processing data acquired by the deformation sensor through a preset algorithm, which will not be described in detail with reference to the preceding content.
At block 102: sending the first information to the satellite through a satellite DTU.
The satellite DTU is configured to send automobile information directly to the satellite. In this way, the monitoring of the automobile will not be affected in a remote region without network.
In this embodiment, the satellite DTU is connected to each sensor through a Modbus communication protocol, which is more efficient and more accurate. Modbus is a serial communication protocol, which was published by Modicon company (now Schneider Electric) in 1979 for the use of Programmable Logic Controller (PLC) communication. Modbus has become an industry standard (De facto) of communication protocols in the industrial field, and is now a common connection mode between industrial electronic devices.
At block 103: receiving and displaying second information from a cloud monitoring platform.
The second information can also be sent to the automobile in addition to being used in the cloud monitoring platform, that is, monitoring the automobile in the cloud monitoring platform and analyzing and judging an operating state of the automobile. In order to make an automobile driver better understand a current operating state of the automobile, a vehicle-mounted computer or an independent computer can receive and display the second information from the cloud monitoring platform. A display place can be a display screen of a center console, which is a better implementation for the driver to understand. It can also be other places that can be displayed, such as a screen of an independent computer.
The receiving process also requires a satellite, that is, a cloud monitoring platform sends second information to a ground gateway station, the ground gateway station forwards the second information to the satellite, and the satellite directly sends the second information to a satellite DTU of the automobile. In this way, the vehicle-mounted computer receives the second information. A large amount of parallel information can be sent at the same time through the ground gateway station, that is, the information can be sent to many automobiles at the same time.
Herein, the ground gateway station is in communication with the cloud monitoring platform through a public mobile communication network.
The aforementioned public mobile communication network can include the 2nd generation (2G) global system for mobile communication (GSM)/code division multiple access (CDMA), time division-synchronous code division multiple access (TD-SCDMA)/code division multiple access 2000 (CDMA 2000)/wideband code division multiple access (WCDMA) of the 3rd generation (3G) mobile communication, time division long term evolution (TD-LTE)/frequency division duplexing long term evolution (FDD-LTE) of the 4th generation (4G) mobile communication and 5th generation mobile networks (5G), etc., which is not limited to this, and can also be other networks that can realize communication.
This embodiment provides a method for monitoring an automobile based on a satellite, and the method can be implemented by a cloud monitoring platform. As shown in
At block 201: receiving first information from the satellite.
In this embodiment, receiving the first information from the satellite includes:
receiving the first information from the satellite through a ground gateway station.
At block 202: acquiring second information by pre-processing the first information.
The pre-processing here refers to the classification, statistics, and graphics of scattered data, such as, eliminating some erroneous and distorted data through classification and statistics, and vividly displaying changes in data by drawing a trend line. Further analysis, reasoning and prediction, etc. can be made, such as analyzing whether an automobile has low tire pressure of a wheel or a high temperature of a wheel hub due to an excessive load, and predicting a probability of damage to an automobile due to an excessive load and the like.
At block 203: sending the second information to the automobile.
Same as the block 101 in the first embodiment, a satellite is required for sending, that is, a cloud monitoring platform sends the second information to a ground gateway station, the ground gateway station forwards the second information to the satellite, and the satellite directly sends the second information to the automobile.
