Detailed Description
As shown in fig. 1, the redundant reliable monitoring system provided by the utility model comprises a whole vehicle upper module and a plurality of tire lower modules, wherein the whole vehicle upper module is installed inside the vehicle and is composed of a reliable starting unit, a multipath alarm unit and an emergency processing unit; the tire lower module is arranged in each automobile tire and consists of a redundant measurement unit and a field processing unit. And each tire lower module and the whole vehicle upper module are communicated in a wireless mode. The reliable starting unit in the upper module of the whole vehicle is provided with a vehicle-mounted information interface, the multipath alarm unit is provided with a remote network interface, and the emergency processing unit is provided with a vehicle-mounted driving interface.
The redundant reliable monitoring system is characterized in that a plurality of sensors are arranged in a redundant measuring unit and are respectively used for realizing pressure measurement, temperature measurement, humidity measurement, electric quantity measurement and motion induction in the automobile tire. The sensors adopt a redundant configuration mode, namely a main sensor and at least one backup sensor are arranged aiming at the same measurement purpose, and each sensor respectively and independently sends a measured signal. In addition, the wireless communication interface between the tire lower module and the vehicle upper module adopts a similar redundant configuration mode. Therefore, correct information of the internal working condition state of the automobile tire can be obtained after the main sensor or the wireless communication interface fails.
The redundant measurement unit is connected with the field processing unit. The field processing unit utilizes an embedded microprocessor in the tire lower module to carry out field processing, including information acquisition, analysis and judgment, data uploading, shielding switching, dormancy or waking up. The information acquisition refers to the acquisition of information such as motion induction, pressure measurement, temperature measurement, humidity measurement, electric quantity measurement and the like. The analysis and judgment means that the internal mechanism of the field configuration scheme is utilized to analyze according to the collected measurement information, and whether the sleep or the wake-up is required to be carried out is judged; uploading data; masking and switching.
Reliable starting unit in the whole vehicle upper module has the functions of: the whole vehicle upper module learns that the vehicle is started and stably runs from vehicle-mounted information interfaces such as a vehicle CAN bus or a GPS receiver, and the like, but does not acquire the uploading data of a certain tire lower module in time, the vehicle upper module sends a command to the tire lower module to request the uploading data or to request the main/standby switching of the motion induction sensor, otherwise, the vehicle upper module switches the communication interfaces.
The multipath alarm unit in the upper module of the whole vehicle not only has LED display and alarm sound alarm adopted in the prior art, but also adopts specific preset voice alarm (can be Chinese such as 'slow air leakage of front right tire', also can be other national languages or dialects, has default presetting and can be set by recording), and comprises remote alarm through a wireless network.
An emergency processing unit in the upper module of the whole automobile acquires relevant information of the capacity reduction of a driver (such as alcoholic strength 'micro-drinking' or fatigue 'yellow' alarm) based on a vehicle-mounted information interface, and the automobile can be automatically controlled to decelerate, lean to the side, brake to stop and the like through a vehicle-mounted driving interface.
As a direct type tire condition monitoring system, it is necessary to manage the amount of electricity in terms of reliability, whether it is an active type with a battery, a passive type that generates electricity by tire motion, or a hybrid type that charges a battery by motion generation. When the electric quantity measuring sensor reflects that the electric quantity is insufficient and an alarm is required, the alarm is given through the field processing unit.
From the perspective of reducing power consumption, the redundant reliable monitoring system should be dormant when the vehicle is parked with the tires stationary and not awake when the vehicle is starting with the tires rotating. Therefore, the motion induction sensor detects the rotation and the static conditions of the tire, and the embedded microprocessor in the tire lower module determines to wake up or sleep according to the detection result. When the tire is just stopped to rotate, the tire lower module should continuously send the current tire condition data to the vehicle upper module.
If all the main sensors in work are normal, how to judge whether the tire condition is normal or not is judged according to the measurement information, and if the tire condition is abnormal, the judgment is important. Because the electricity consumed by the uploading communication occupies an absolute position, if the communication is required to be uploaded frequently, the communication is alarmed at a medium frequency if the communication is not required to be uploaded frequently, and if the communication is required to be uploaded normally, the communication is alarmed at a sparse frequency. For example, the temperature is high enough to cause tire burst; the rapid deflation of the tire is also very critical.
Taking the tire pressure as an example, for example, the optimal value of the pressure in a certain automobile tire is 2.5 atmospheres, as shown in fig. 2, when the tire pressure is greater than 2.0, the whole automobile can still run; however, if the tire pressure is lower than 2.0 and continues to decrease, the resistance to rolling operation of the tire increases significantly. The embedded microprocessor in the tire lower module can judge whether the tire pressure is abnormal, slow air leakage or fast air leakage according to the relationship between the tire rolling resistance and the tire pressure shown in fig. 2.
On the other hand, how can one know that the main sensor in operation is abnormal by itself? There are several solutions to this, for example, if the measurement data is not available, or the measurement data is scrambled all the time, the embedded microprocessor in the tire level module can autonomously determine that the master sensor is out of order. When the whole vehicle upper module learns that the vehicle is started to run through the vehicle-mounted information interface, and the tire lower module does not upload related data, the main motion induction sensor is possibly abnormal. When the tire pressure is found to be abnormal during regular maintenance and maintenance, an alarm is not obtained during recent driving, and the main pressure sensor may fail.
When the embedded microprocessor in the lower module of the tyre finds that the main sensor is abnormal, the detection interface is automatically shielded, and the backup sensor interface is automatically changed to obtain the measurement data. If the main sensor is found to be abnormal through other modes, the whole vehicle upper module sends a command to the tire lower module, the tire lower module shields the corresponding detection interface after receiving the command, and the backup sensor interface automatically obtains the measurement data.
It is right above the utility model provides a redundant reliable monitoring system of automobile tire internal operating mode has carried out detailed description, nevertheless obviously the utility model discloses a concrete implementation form is not limited to this. Various obvious changes to the invention without departing from the scope of the claims of the invention are within the protection scope of the invention for a person with ordinary skill in the art.
