Description

Technical Field

[0001] This utility model relates to the field of automobile chassis, and in particular to a humidity detection and early warning system for vehicle air tanks. Background Technology

[0002] With rapid economic development, the logistics and machinery industries have an increasing demand for heavy-duty vehicles, leading to the widespread adoption of air-pressure brakes. Drivers typically rely on experience to determine whether the air reservoir needs draining. However, the complex operating conditions of vehicles mean that misjudgments can cause moisture to enter the brake chamber and brake valve body along with the compressed air, affecting vehicle braking safety. Similarly, the dryer filter should be replaced every six months or 100,000 kilometers. However, the performance of different products can affect its replacement, potentially leading to premature replacement (wasting resources) or delayed replacement (damaging the brake valve body, and in severe cases, brake failure). Utility Model Content

[0005] The vehicle air tank humidity detection system includes an air compressor, a dryer, an air tank, and a humidity sensor; the air compressor, dryer, and air tank are connected by pipelines, and the humidity sensor is installed on the air tank.

[0007] An early warning system based on any of the above-described gas storage tank humidity detection systems, characterized in that the early warning system includes a controller;

[0009] Preferably, the early warning system further includes an electrically controlled water discharge valve, which is installed on the gas storage tank and is controlled and connected by a controller.

[0010] Preferably, the dryer is connected and controlled by a controller.

[0011] Compared with the prior art, the present invention has the following beneficial technical effects:

[0012] This invention can detect the moisture content of the air storage cylinder and automatically control the water discharge to prevent water vapor from entering the brake chamber, thereby avoiding affecting the safe driving of the vehicle; at the same time, it controls the backflushing of the dryer to improve the drying effect and service life of the dryer.

[0016] This utility model provides a vehicle air tank humidity detection system, including an air compressor 1, a dryer 3, an air tank 6, and a humidity sensor 8; the air compressor 1, dryer 3, and air tank 6 are connected by pipelines, and the humidity sensor 8 is installed on the air tank 6.

[0017] The humidity sensor 8 uses a capacitive humidity-sensitive element sensor.

[0018] This utility model also provides an early warning system based on the above-mentioned vehicle air tank humidity detection system, the early warning system including a controller 10;

[0019] The humidity sensor is controlled and connected by controller 10.

[0020] The early warning system also includes an electrically controlled water discharge valve 7, which is installed on the gas storage tank 6 and is controlled and connected by the controller 10.

[0021] Dryer 3 is controlled and connected by controller 10.

[0022] Example 1

[0023] like Figure 1 As shown, the air compressor 1 is connected to the dryer 3 via the brake steel pipe 2, and the dryer 3 is connected to the air storage tank 6 via the four-circuit 4. The humidity sensor 8 is installed on the air storage tank 6 to detect the humidity of the air inside the air storage tank 6.

[0024] Example 2

[0025] like Figure 2 As shown, the air compressor 1 is connected to the dryer 3 via the brake steel pipe 2, and the dryer 3 is connected to the air tank 6 via the four-circuit 4. The electrically controlled drain valve 7 and the humidity sensor 8 are installed on the air tank 6. The controller is connected to the electrically controlled drain valve 7, the humidity sensor 8, and the dryer 3 via the wiring harness 9. Its working principle is as follows:

[0026] After the vehicle is powered on, the humidity sensor 8 is powered on and performs a self-test, transmitting humidity information to the controller 10. When the humidity exceeds a certain upper limit, the controller 10 sends a signal to the electronically controlled drain valve 7. Upon receiving the information, the electronically controlled drain valve 7 automatically drains water. When the humidity sensor 8 detects that the gas humidity exceeds the set value, it sends an alarm message to the controller. The controller 10 sends a backflush command to the dryer 3, and the dryer 3 performs a backflush operation. If the gas humidity stored in the air tank 6 exceeds the set value within a set time, the controller 10 sends a message to extend the filter life, and the instrument displays an alarm message "Dryer filter needs to be replaced".

[0027] Example 3

[0028] Based on implementation 1 or implementation 2, connecting this system to the vehicle's brake chamber can effectively prevent moisture from entering the brake chamber and avoid affecting the vehicle's safe operation.
