The present disclosure will be described in further detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for the purpose of explaining the present disclosure and are not intended to limit the present disclosure.
The present embodiment provides a method for dynamically monitoring the working state of a vehicle, and the method can be realized by an on-board computer or a separately installed computer. As shown in
Step 101: a monitoring unit is woken up according to a vehicle starting signal.
In an implementation mode, the waking-up of the monitoring unit according to the vehicle starting signal includes:
the vehicle starting signal is obtained through the state of an ignition wire of the vehicle; and
the monitoring unit is woken up according to the vehicle starting signal through a wireless waking-up component.
For the sake of power saving, the monitoring unit is generally in a sleep state before being awakened. Moreover, after being awakened, the monitoring unit will re-enter the sleep state if the response of the on-board computer is not received within a preset period of time. In the present embodiment, after being awakened, data reporting is conducted once every 5 minutes, and the response is received every time data reporting is conducted. When no response is received for 3 consecutive times, the monitoring unit re-enters the sleep state. The wireless waking-up component herein can adopt the principle of Radio Frequency (RF), i.e. the frequency range of a wireless signal is between 300 kHz and 300 GHz, which is a widely used wireless communication signal.
Step 102: the load of the vehicle, the tire pressure of a wheel and the temperature of a wheel hub are acquired through the monitoring unit.
In one implementation mode, the acquisition of the load of the vehicle, the tire pressure of the wheel and the temperature of the wheel hub through the monitoring unit includes:
the deformation data of the vehicle hub after the vehicle hub is loaded is acquired through a deformation sensor of the monitoring unit, so as to acquire the load of the vehicle;
the tire pressure of the wheel is acquired through a pressure sensor of the monitoring unit; and
the temperature of the vehicle hub is acquired through a temperature sensor of the monitoring unit.
Herein, when the vehicle hub is loaded, there will be slight deformation, which can be detected by the deformation sensor. Then, the load of the vehicle hub, that is, the load of the vehicle, can be calculated based on the detected slight deformation of the hub. The pressure sensor can be arranged on the inner wall of the wheel, and the temperature sensor can be arranged on the surface of the vehicle hub.
In one implementation mode, the method further includes:
an acceleration value of the vehicle is acquired through an acceleration sensor; and
the acquired load value of the vehicle is corrected according to the acceleration value of the vehicle.
Since the deformation of the wheel hub of the vehicle will change even if the load of the vehicle does not change in the acceleration process, the obtained load value of the vehicle needs to be corrected according to the acceleration value.
Step 103: the working state of the vehicle is determined according to the load of the vehicle, the tire pressure of the wheel and the temperature of the wheel hub.
In one implementation mode, the determination of the working state of the vehicle according to the load of the vehicle, the tire pressure of the wheel and the temperature of the wheel hub includes:
the working state of the vehicle is determined to be abnormal and alarm information is set out if any one of the load of the vehicle, the tire pressure of the wheel and the temperature of the wheel hub exceeds a corresponding upper limit value;
otherwise, the working state of the vehicle is determined to be normal.
In one implementation mode, the method further includes:
the determined working state of the vehicle is sent to a vehicle cloud platform through a public mobile communication network.
In this way, the vehicle can be controlled and dispatched through the cloud platform, for example, transportation companies can manage truck drivers through the cloud platform, and the data of the cloud platform can also be archived for the public security department and other government departments to consult.
The public mobile communication network herein may be the second-generation (2G) global system for mobile communication (GSM)/code division multiple access (CDMA), the third-generation (3G) time division-synchronous code division multiple access (TD-SCDMA)/code division multiple access 2000 (CDMA2000)/wideband code division multiple access (WCDMA) and the fourth-generation (4G) time division long term evolution (TD-LTE)/frequency division duplexing long term evolution (FDD-LTE), but is not limited thereto, and may also be other networks capable of realizing communication.
Further, in order to better understand the present embodiment, the following describes the specific flow of the method for dynamically monitoring the working state of a vehicle according to the embodiment of the present disclosure, as shown in
Step 201: whether the vehicle is started is confirmed. The vehicle starting signal is obtained through the state of the ignition wire of the vehicle. If yes, step 202 is executed, otherwise the last step is returned.
Step 202: the monitoring unit is woken up. The monitoring unit is woken up through the wireless waking-up component.
Step 203: the load of the vehicle, the tire pressure of the wheel and the temperature of the wheel hub are acquired. The deformation data of the vehicle hub after the vehicle hub is loaded are acquired through the deformation sensor of the monitoring unit, so as to acquire the load of the vehicle; the tire pressure of the wheel is acquired through the pressure sensor of the monitoring unit; and the temperature of the vehicle hub is acquired through the temperature sensor of the monitoring unit.
Step 204: whether the working state of the vehicle is abnormal is determined. The working state of the vehicle is determined to be abnormal and alarm information is sent out if any one of the load of the vehicle, the tire pressure of the wheel and the temperature of the wheel hub exceeds a corresponding upper limit value; otherwise the working state of the vehicle is determined to be normal.
If the working state is abnormal, step 205 is executed, otherwise step 207 is executed.
Step 205: an alarm signal is sent out. The alarm signal may be an acousto-optic alarm.
Step 206: the information that the working state of the vehicle is abnormal is sent to the cloud platform. In order to save the resources of the cloud platform, only the information that the working state of the vehicle is abnormal is sent to the cloud platform, and normal information is not sent.
Step 207: the working state information of the vehicle is sent to a user. For example, it is sent to a display screen of a center console of the vehicle. The sending principle may be ZigBee protocol.
