For those skilled in the art to understand the present invention more easily, in an embodiment of the present invention, Fig. 2 is based on the automobile oil tank data, the method for fault analysis of the automobile mailbox system, as shown in Fig. 2, the method includes:

S210, collecting vehicle fuel tank data.

In the embodiment of the present invention, the fuel tank data of the automobile can be collected through the collection module in the data collection and storage system based on the fuel tank pressure.

Wherein, the collected data of the automobile fuel tank includes the input/output voltage of the automobile fuel tank and the pressure value in the automobile fuel tank.

In the embodiment of the present invention, the input/output voltage of the fuel tank of the automobile can be collected by the collection module, for example, the collection module includes a first collection unit and a second collection unit.

For example, taking the voltage signal collected by the first collection unit as an example, the collection of the voltage signal by the first collection unit can be understood as collecting the fuel tank data of the vehicle by collecting the CAN message signal of the vehicle through the OBD port. For example, when collecting voltage signals through the first acquisition unit, the first acquisition unit is connected to the OBD main line, the OBD main line is connected to the OBD connection part, and the OBD connection part is connected to the OBD interface of the main driver of the vehicle, so that the first acquisition unit can be connected to the OBD interface of the main driver of the vehicle. The voltage signal of the pressure fuel tank sensor is collected, wherein the voltage signal is the voltage signal of the pressure fuel tank sensor monitored by the vehicle itself.

As another example, when the voltage signal is collected by the second acquisition unit, the second acquisition unit includes a first signal input interface and a second signal input interface, wherein each signal input interface is connected to a hard wire, and the hard wire is a twisted pair structure. Wherein, the twisted pair structure includes a first twisted pair and a second twisted pair, and the first signal input interface and the second signal input interface are respectively connected to the first twisted pair and the second twisted pair, wherein the first twisted pair The wires and the second twisted pair each include a first wire bundle and a second wire bundle.

Therefore, the output voltage of the pressure fuel tank sensor can be sent to the engine, so that the engine can output the pressure value in the fuel tank of the vehicle based on the pressure value and voltage conversion curve. For example, a schematic diagram of the pressure value and voltage conversion curve can be shown in FIG. 3 .

As another example, the state of the voltage data is that the input voltage collected by the first acquisition unit is 5V, the output voltage is 0V, the input voltage collected by the second acquisition unit is 5V, the output voltage is 0V, and the pressure value in the automobile fuel tank is not less than the first When the three thresholds and the corresponding auxiliary troubleshooting behavior are "replace the sensor", and the auxiliary troubleshooting result is "the fault phenomenon disappears after replacing the sensor", it can be determined that the fault behavior is that the internal power line/output line of the pressure sensor is welded/disconnected.

For another example, the state of the voltage data is that the input voltage collected by the first acquisition unit is 5V, the output voltage is 0V, the input voltage collected by the second acquisition unit is 5V, the output voltage is a value other than 0V, and the pressure value in the automobile fuel tank is not less than the third threshold, and the corresponding auxiliary investigation behavior is "replace the wire harness" or "re-insert the plug", and the auxiliary inspection result is "the fault disappears after the wire harness is replaced or the plug is re-inserted", it can be determined that the fault behavior is There is a disconnection or poor contact between the output voltage harness of the pressure sensor and the receiving end of the transmitter.

As another example, the state of the voltage data is that the input voltage collected by the first acquisition unit is 5V, the output voltage is 5V, the input voltage collected by the second acquisition unit is 5V, the output voltage is 5V, and the pressure value in the automobile fuel tank is not greater than the first When the four thresholds and the corresponding auxiliary inspection behavior are "sensor unit test", and the auxiliary inspection result is "sensor unit test qualified", it can be determined that the fault behavior is a short circuit between the power line of the pressure sensor and the output signal feedback line.

For example, the state of the voltage data is that the input voltage collected by the first acquisition unit is 5V, the output voltage is 0V, the input voltage collected by the second acquisition unit is 5V, the output voltage is 0V, and the pressure value in the automobile fuel tank is not less than the third When the threshold value and the corresponding auxiliary inspection behavior are "sensor unit test", and the auxiliary inspection result is "sensor unit test qualified", it can be determined that the fault behavior is a short circuit between the ground wire in the pressure sensor connection line and the output signal feedback line.
