Description of drawings
Fig. 1 is structural representation of the present invention.
Among the figure, 1, gas tank 2, gas boost pump 3, normally closed gas open-close valve 4, gas pressure sensor 5, ECU (Electrical Control Unit) 6, tire admission piece 7, flue branch road 8, warning device.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
In the drawings, whole system monitoring and gas filled device mainly are made of gas tank 1, gas boost pump 2, normally closed gas open-close valve 3, gas pressure sensor 4, ECU (Electrical Control Unit) 5, tire admission piece 6, gas pipe line 7, warning device 8.A normally closed gas open-close valve 3 and gas pressure sensor 4 all are installed on the flue branch road of every axletree one side, and described normally closed gas open-close valve 3 is connected with described gas tank 1 by gas pipe line 7; Described gas pressure sensor 4 is connected with described ECU (Electrical Control Unit) 5, described gas pressure sensor 4 with the tire pressure electric signal transmission of the respective line that detects to ECU (Electrical Control Unit) 5; , described ECU (Electrical Control Unit) 5 is used for controlling the switch of described normally closed gas open-close valve 3; The terminal of described gas pipe line 7 is connected with the tire admission piece 6 of every axletree one side, and described warning device 8 is connected with described ECU (Electrical Control Unit) 5.
Described gas tank 1 is as the air storage part of whole inflation, and 1 pair of tire of gas tank is inflated.
Tire pressure for vehicle, the tire pressure of the vehicle specifies that has may be higher than the air storage pressure of gas tank 1, gas tank 1 one ends can be connected gas boost pump 2, by gas boost pump 2 air pressure is elevated to the requirement of regulation, the high pressure gas after boosting link to each other with normally closed gas open-close valve 3 by gas pipe line.Adjust the air pressure adjusting valve of gas boost pump 2, making the high pressure gas after boosting is the standard pressure of tire.
The gas pipe line 7 of every axletree one side communicates with the tire admission piece 6 of a corresponding side, and tire admission piece 6 opens all the time, and the gas pipe line 7 that guarantees every axletree one side communicates with gas in two tires of this side.Namely among the figure two of every axletree one side the tire pressure of wheel is identical side by side.
Because flue branch road 7 terminals communicate with being connected with the admission piece 6 of all tire, the air pressure of corresponding axletree one side that the gas pressure sensor 4 of every axletree one side will detect converts magnitude of voltage to and is input in the ECU (Electrical Control Unit) 5.The magnitude of voltage of a standard of ECU (Electrical Control Unit) 5 interior settings, the size of its standard voltage value equal the magnitude of voltage that gas pressure sensor 4 detects tire standards air pressure.The magnitude of voltage of the gas pressure sensor 4 on the flue branch road 7 of every axletree one side wheel tire and the standard voltage value of ECU (Electrical Control Unit) 5 interior settings compare.When the magnitude of voltage of axletree one side gas pressure sensor 4 was lower than the magnitude of voltage of ECU (Electrical Control Unit) 5 settings, the control circuit output high level of axletree one side of 5 pairs of detections of ECU (Electrical Control Unit) was opened normally closed gas open-close valve 3 and warning device 8; This moment, gas tank 1 interior high pressure gas entered the gas pipe line 7 of a corresponding side, by tire admission piece 6 inflations of flue branch road 7 to a corresponding side.When gas pressure sensor 4 magnitudes of voltage of axletree one side were greater than or equal to the magnitude of voltage of ECU (Electrical Control Unit) 5 settings, the control circuit output low level of axletree one side of 5 pairs of detections of ECU (Electrical Control Unit) was closed normally closed gas open-close valve 3 and warning device 8; This moment, gas tank 1 interior high pressure gas can't enter gas pipe line 7, and device stops to tyre inflating.
Because the road surface of Vehicle Driving Cycle may cause the air pressure in the tire to fluctuate up and down at standard pressure, cause the frequent switching of normally closed gas open-close valve 3, in order to reduce the frequent switching of normally closed gas open-close valve 3, ECU (Electrical Control Unit) 5 also can be set comparative figure and change in a scope, when comparative figure during less than or equal to a certain variation range, the control circuit output low level of axletree one side of 5 pairs of detections of ECU (Electrical Control Unit) is also closed warning device 8; When comparative figure during greater than a certain variation range, the control circuit of axletree one side of 5 pairs of detections of ECU (Electrical Control Unit) output high level is also opened warning device 8.The setting comparative figure changes in a scope can reduce tire pressure because the frequent switching that causes normally closed gas open-close valve 3 when standard pressure changes up and down.
