Example 1
Because the dangerous chemical vehicle structure is more complicated, 12 signals actually received by 3 tire pressure receivers are not completely effective or stable, so the acquisition of the actual information for evaluating the tire pressure state is required to reasonably match the tire pressure sensor and the tire pressure receiver according to the vehicle structure and the signal intensity, and the wireless signals of all the tire pressure sensors can be stably received.
As shown in fig. 1, a configurable tire pressure monitoring system of a commercial vehicle is applied to a dangerous chemical vehicle with 12 wheels, and comprises a power supply 1, 12 tire pressure sensors 2, 3 tire pressure receivers (respectively comprising a first tire pressure receiver 3-1, a second tire pressure receiver 3-2 and a third tire pressure receiver 3-3) and a tire pressure controller 4; wherein the power supply supplies power to the whole monitoring system. The 12 tire pressure sensors 2 are correspondingly arranged on each wheel rim and are used for sampling tire pressure and temperature information in real time. According to the vehicle structure and the wheel distribution, 3 tire pressure receivers are flexibly distributed and installed on a vehicle chassis; the 12 tire pressure sensors are respectively connected with the first tire pressure receiver 3-1, the second tire pressure receiver 3-2 and the third tire pressure receiver 3-3 through wireless networks, namely each tire pressure receiver receives tire pressure and temperature signals sent by the 12 tire pressure sensors; meanwhile, the 3 tire pressure receivers are all connected with the tire pressure controller 4 and transmit the tire pressure and temperature information to the tire pressure controller through the CAN network, and the tire pressure controller 4 also configures the number of the receivers through power distribution control of the receivers.
Specifically, the tire pressure controller comprises a power interface 4-1, a filter interface 4-10, an overvoltage protection circuit 4-2, a direct current power supply conversion circuit 4-3, a receiver power supply control circuit 4-4, a microcontroller 4-5, 3 receiver power supply driving circuits (a first receiver power supply driving circuit 4-7, a second receiver power supply driving circuit 4-8, a third receiver power supply driving circuit 4-9 respectively) and a receiver CAN interface 4-6. The power interface 4-1, the overvoltage protection circuit 4-2 and the direct current power supply conversion circuit 4-3 are sequentially connected, the direct current power supply conversion circuit 4-3 is respectively connected with the receiver power supply control circuit 4-4 and the microcontroller 4-5, the microcontroller 4-5 is respectively connected with the receiver power supply control circuit 4-4 and the receiver CAN interface 4-6, the receiver power supply control circuit 4-4 is respectively connected with the first receiver power supply driving circuit 4-7, the second receiver power supply driving circuit 4-8 and the third receiver power supply driving circuit 4-8, and the CAN interface 4-6 is respectively connected with the first tire pressure receiver 3-1, the second tire pressure receiver 3-2 and the third tire pressure receiver 3-3.
The microcontroller 4-5 is connected with the receiver power supply control circuit 4-5, so that the 3 tire pressure receivers are controlled to supply power through the 3 receiver power supply driving circuits, and the number of the receivers is configurable. Wherein the first receiver power driving circuit 4-7 is connected with the first tire pressure receiver 3-1, the second receiver power driving circuit 4-8 is connected with the second tire pressure receiver 3-2, and the third receiver power driving circuit 4-9 is connected with the third tire pressure receiver 3-3.
The tire pressure monitoring system in the embodiment further comprises a whole-vehicle CAN interface 4-11, wherein the whole-vehicle CAN interface 4-11 is connected with the microcontroller 4-5, and the tire information is transmitted to the display interface through the CAN network.
Working principle:
according to the structural design of the dangerous chemical vehicle, 3 tire pressure receivers are arranged at 3 different positions of a vehicle chassis, and the 3 receivers can all receive the tire pressure and temperature information of 12 tires. In order to reduce the energy consumption of the system, only the data received by the first tire pressure receiver and the second tire pressure receiver are needed under the condition that the tire pressure information is ensured to be stable. The object is to achieve a configuration of the number of receivers. The specific method comprises the following steps:
the vehicle power supply 1 is connected to the power interface 4-1, and a direct current voltage-stabilized power supply is provided for the microcontroller 4-5 and the receiver power supply control circuit 4-4 by the direct current power supply conversion circuit 4-3 after passing through the filter circuit 4-10 and the overvoltage protection circuit 4-2. The receiver power supply driving circuit of the tire pressure controller 4 is connected with the tire pressure receiver 3. The microcontroller 4-5, the receiver power supply control circuit 4-4 and the receiver power supply driving circuit of the tire pressure controller 4 realize the configurable power supply to the tire pressure receiver 3 (for example, when the first receiver power supply driving circuit and the second receiver power supply driving circuit are controlled to work and the third receiver power supply driving circuit is not operated, namely, the first tire pressure receiver and the second tire pressure receiver are operated and the third tire pressure receiver is not operated), so as to further realize the configurable number of the receivers, reduce the power consumption of the system and reduce the external electromagnetic interference. The tire pressure receiver 3 is flexibly distributed and installed on the chassis of the vehicle according to the vehicle structure and the wheel distribution, so that the wireless signals sent by the tire pressure sensor 2 are stably received and transmitted.
Example 2
The commercial vehicle has a tractor and a trailer, and the tractor can frequently replace the trailer. The tire pressure sensors of the trailer configurations produced by different manufacturers may be different in model, so that there are two tire pressure sensors of different models on the same vehicle at the same time. For the situation of the tractor and the trailer, for example, the tire pressure sensor of the tractor is a tire pressure sensor A, the tire pressure sensor of the trailer is a tire pressure sensor B, and the receiver CAN interfaces 4-6 of the tire pressure controller 4 are respectively connected with each tire pressure receiver. The microcontroller 4-5 of the tire pressure controller 4 is respectively connected with the receiver CAN interface 4-6 and the whole vehicle CAN interface 4-11. When two tire pressure sensors with different types exist on one vehicle at the same time, the microcontroller 4-5 configures each tire pressure receiver through the receiver CAN interface 4-6, and distributes different numbers of receivers to respectively receive and transmit wireless signals to the tire pressure sensors with different types, so that the problem that two tire pressure sensors are compatible simultaneously on the same vehicle is solved.
