The present invention relates to a water level detecting system, and more particularly to an intelligent water level detecting system and method thereof for detecting a change in water level of an outdoor parking space.

In today's daily life, vehicles have become an indispensable part of people's lives. In an era of increasing vehicle demand, vehicle parking lots are often in short supply. Vehicle parking lots can be divided into indoor parking lots and outdoor parking lots. Indoor parking lots, such as parking towers or underground parking lots, can be used to protect the vehicles from the wind and rain, in addition to parking for the owners.

However, there are still many parking lots belonging to outdoor parking lots. In the case of rainy days, vehicles parked in outdoor parking lots often become water-buffered vehicles due to excessive water in the road area, causing the vehicle to be damaged or scrapped. Therefore, there is a need for a water level detection system that can solve the problem that the vehicle becomes a water tanker when the road area is too high.

The embodiment of the invention provides an intelligent water level detecting system, which is suitable for an outdoor parking space. The intelligent water level detecting system includes a carrying device and a lifting device.

The water level sensor is configured to sense a water level change around the vehicle and output at least one water level sensing signal. The wireless module is configured to generate at least one control signal according to the water level sensing signal number. The lifting device comprises at least one lifting rod. The two ends of the lifting rod are respectively coupled to the carrying device and the lifting device, and the lifting device is used for controlling the ascending or descending action of the carrying device according to the control signal. The intelligent water level detecting system sets a first threshold value and a second threshold value. When the water level sensor senses that the water level around the vehicle is greater than or equal to the first threshold value and lower than the second threshold value, the lifting device adjusts the carrying device. To the first height. When the water level sensor senses that the water level around the vehicle is greater than or equal to the second threshold, the lifting device adjusts the carrying device to the second height.

The embodiment of the invention provides a smart water level detecting method, which is suitable for a smart water level detecting system. The intelligent water level detecting system includes a carrying device and a lifting device. The carrying device further includes at least one water level sensor, a wireless module, and at least two pressure sensors. In this intelligent water level detecting method, firstly, when the pressure sensor senses that the vehicle enters the carrying device, the water level sensor starts to sense the water level change around the vehicle. When the water level sensor senses that the water level around the vehicle is lower than the first threshold, the wireless module outputs at least one control signal to the lifting device, so that the lifting device adjusts the carrying device to the initial height. When the water level sensor senses that the water level around the vehicle is greater than or equal to the first threshold and lower than the second threshold, the wireless module outputs a control signal to the lifting device, so that the lifting device adjusts the carrying device to the first height. When the water level sensor senses that the water level around the vehicle is greater than or equal to the second threshold, the wireless module outputs a control signal to the lifting device, so that the lifting device adjusts the carrying device to the second height.

In summary, the intelligent water level detecting system and the intelligent water level detecting method provided by the embodiments of the present invention can automatically detect the water level change around the vehicle, and adjust the height of the carrying device correspondingly according to the water level change. That is to say, the height of the vehicle from the ground will be adjusted correspondingly according to the change of the water level.

Please refer to FIG. 1A. FIG. 1A is a block diagram of a smart water level detecting system according to an embodiment of the present invention. The intelligent water level detecting system 1 includes a carrying device 10 and a lifting device 11. The carrying device 10 is used to carry a vehicle (not shown). The carrying device 10 includes at least one water level sensor 101, a wireless module 102, and at least two pressure sensors 103a, 103b. The water level sensor 101 and the pressure sensors 103a, 103b are all connected to the wireless module 102 via wireless communication (for example, Bluetooth). The lifting device 11 is for controlling the ascending or descending action of the carrying device 10, and includes at least one lifting rod 111, a wireless receiver 112 and at least one motor 113. The two ends of the lifting rod 111 are respectively coupled to the carrying device 10 and the lifting device 11 .

Pressure sensors 103a, 103b may be provided on the gear wheels 12a, 12b, respectively, for sensing whether the vehicle enters the carrier device 10. After the pressure sensors 103a, 103b sense that the vehicle enters the carrier device 10, the pressure sensors 103a, 103b respectively output pressure sensing signals to the wireless module 102. Then, the wireless module 102 activates the smart water level detecting system 1 according to the pressure sensing signal.

It is worth mentioning that the embodiment of the present invention places the pressure sensors 103a, 103b on the gear wheels 12a, 12b, respectively. However, the present invention does not limit the position at which the pressure sensors 103a, 103b are disposed.

The water level sensor 101 is configured to sense a water level change around the vehicle and generate at least one water level sensing signal. That is to say, after the smart water level detecting system 1 is activated, the water level sensor 101 starts to sense the water level change around the vehicle, and outputs the water level sensing signal to the wireless module 102 through wireless communication. Then, the wireless module 102 generates at least one control signal according to the water level sensing signal, and outputs the control signal to the wireless receiver 112 through wireless communication.

The wireless receiver 112 receives the control signal and outputs the control signal to the motor 113. Finally, the motor 113 controls the lifting rod 111 correspondingly according to the control signal to adjust the height of the carrier 10.

In the embodiment of the present invention, the intelligent water level detecting system 1 sets a first threshold value and a second threshold value for determining the degree of accumulation of the water level around the vehicle. In addition, the intelligent water level detecting system 1 sets an initial height, a first height, and a second height for adjusting the ground height of the carrier device 10. The initial height is the height of the front load device 10 before the smart water level detecting system 1 starts. The initial height is tangent to the ground 14. The first height is higher than the initial height and the second height is higher than the first height.

When the water level sensor 101 senses that the water level around the vehicle is below the first threshold, the wireless module 102 outputs a control signal to the lifting device 11 such that the motor 113 correspondingly adjusts the carrier device 10 to the initial height. When the water level sensor 101 senses that the water level around the vehicle is greater than or equal to the first threshold and lower than the second threshold, the wireless module 102 outputs a control signal to the lifting device 11 so that the motor 113 adjusts the carrying device 10 correspondingly. To the first height. When the water level sensor 101 senses that the water level around the vehicle is greater than or equal to the second threshold, the wireless module 102 outputs a control signal to the lifting device 11 such that the motor 113 correspondingly adjusts the carrier device 10 to the second height.

For example, when the smart water level detecting system 1 has not been activated, the grounding height of the carrying device 10 is equal to the initial height. When the smart water level detecting system 1 is activated, the water level sensor 101 starts sensing the water level change around the vehicle. When the water level sensor 101 senses that water is accumulated around the periphery of the vehicle, but the water level has not reached the first threshold, the wireless module 102 will judge that the current accumulated water level does not affect the vehicle. Therefore, the carrier 10 will maintain the initial height.

When the water level sensor 101 senses the water level accumulated around the vehicle to reach the first threshold, the wireless module 102 will determine that the current accumulated water level will cause harm to the vehicle. Therefore, the wireless module 102 will output a control signal to the wireless receiver 112 of the lifting device 11 such that the lifting device 11 adjusts the carrier device 10 to the first height. When the water level sensor 101 senses that the accumulated water level around the vehicle continues to accumulate to the second threshold, no The line module 102 will again output a control signal to the wireless receiver 112 of the lifting device 11 such that the lifting device 11 adjusts the carrier device 10 to a second level.

When the water level sensor 101 senses that the water level accumulated around the vehicle drops from above the second threshold to between the first threshold and the second threshold, the wireless module 102 outputs a control signal to the lifting device 11 The wireless receiver 112 causes the lifting device 11 to adjust the carrier device 10 to a first height. Similarly, when the water level sensor 101 senses that the water level accumulated around the vehicle drops below the first threshold, the wireless module 102 will output a control signal to the wireless receiver 112 of the lifting device 11 so that the lifting device 11 will The carrier device 10 is adjusted to an initial height.

It should be noted that the initial height, the first height, and the second height are set by way of example only in the embodiments of the present invention. Those skilled in the art can also set a plurality of heights so that the carrying device 10 can be adjusted in stages, which is not limited by the present invention.

Please refer to FIG. 1B together. FIG. 1B is a schematic diagram of a smart water level detecting system according to an embodiment of the present invention. Briefly, when the water level sensor 101 senses that the water level accumulated around the vehicle reaches a certain level (for example, up to a first threshold), the lifting device 11 raises the carrying device 10 such that the grounding height of the carrying device 10 is high. Above the ground 14, to protect the vehicle from excessive water soaking.

Please refer to FIG. 2. FIG. 2 is a schematic diagram of a wireless remote controller of the smart water level detecting system of the present invention.

Furthermore, the user can control the opening or closing of the intelligent water level detecting system 1 by himself. In addition, the user can also control the height of the carrier device 10 through the wireless remote controller 20. That is to say, the user can adjust the height of the carrying device 10 (for example, from the initial height to the first height) after stopping the vehicle.

Please refer to FIG. 3. FIG. 3 is a practical application diagram of the intelligent water level detecting system of the present invention. As can be seen from FIG. 3, the embodiment of the present invention can connect the smart water level detecting system 1 and the remote server 31 through the Internet 30. The remote server 31 is coupled to the operation As interface 32. The remote server 31 can be placed in a remote central monitoring center. The wireless module 102 can output the water level sensing signal to the remote server 31. The remote server 31 presents the water level change information around the vehicle to the operation interface 32 according to the water level sensing signal. The monitor can monitor the water level change around the vehicle and the current height of the carrier device 10 through the operation interface 32. In addition, the monitor can also remotely control the intelligent water level detecting system 1 through the operation interface 32. For example, the monitor can turn the smart water level detecting system 1 on or off through the operation interface 32, or control the height of the carrying device 10.

In the embodiment of the present invention, the lifting device 11 further includes an alarm module (not shown). The alarm module includes at least one light emitting diode and at least one buzzer. The alarm module is coupled to the wireless receiver 112 for issuing an alarm to notify the user when the vehicle is not moving normally. For example, when the smart water level detecting system 1 is activated and the pressure sensors 12a, 12b sense the movement of the vehicle, the wireless module 102 will judge that the vehicle is abnormally moving. At this time, the wireless module 102 will output an alert signal to the alarm module, so that the LED of the alarm module starts to illuminate, and the buzzer sounds an alarm. At the same time, the wireless module 102 outputs the warning signal to the remote server to inform the monitor that the vehicle is currently moving abnormally.

In other embodiments, the carrier device 10 further includes at least one photo sensor 104. The light sensor 104 senses whether the vehicle enters the carrier device 10 through a change in brightness. When the pressure sensors 103a, 103b and the light sensor 104 both sense that the vehicle enters the carrier device 10, the smart water level detecting system 1 is automatically activated, and the water level sensor 101 starts to sense the water level around the vehicle. Variety. Additionally, light sensor 104 can be used to assist in determining if the vehicle is being moved abnormally. Specifically, when the smart water level detecting system 1 is activated, the pressure sensors 103a, 103b sense the vehicle movement, and the light sensor 104 senses the brightness change, the wireless module 102 will determine that the vehicle is not Moves normally and outputs a warning signal.

Next, please refer to FIG. 4. FIG. 4 is a schematic flow chart of the smart water level detecting method of the present invention. The intelligent water level detecting method is applicable to the above intelligent water level detecting system 1.

First, in step S401, when at least two pressure sensors of the carrying device sense that the vehicle enters the carrying device, the smart water level detecting method is automatically executed. Then, at least one water level sensor of the carrying device starts to sense the water level change around the vehicle, and outputs at least one water level sensing signal to the wireless module of the carrying device, so that the wireless module outputs at least one control signal and correspondingly controls the lifting Device. It is worth mentioning that before the intelligent water level detection method is activated, the carrying device is at an initial height, wherein the initial height is tangent to the ground. In step S402, the water level sensor determines whether the water level around the vehicle reaches the first threshold. When the water level sensor determines that the water level around the vehicle is greater than or equal to the first threshold, it proceeds to step S403. Conversely, when the water level sensor determines that the water level around the vehicle is lower than the first threshold, it proceeds to step S404.

In step S403, the lifting device performs an ascending motion and adjusts the carrier device from an initial height to a first height, wherein the first height is higher than the initial height. Then, when the carrying device is adjusted to the first height, the water level sensor will continue to sense the water level change around the vehicle, and proceeds to step S405.

In step S404, the lifting device performs a lowering motion and adjusts the carrying device to an initial height. Next, the water level sensor will continue to sense the water level change around the vehicle and return to step S402. That is, when the water level sensor does not sense that the water level is greater than or equal to the first threshold, the carrier will remain at the initial height.

In step S405, the water level sensor determines whether the water level around the vehicle reaches the second threshold. When the water level sensor determines that the water level around the vehicle is greater than or equal to the second threshold, then proceeds to step S406. Conversely, when the water level sensor determines that the water level around the vehicle is lower than the second threshold, it proceeds to step S407.

In step S406, the lifting device performs a rising motion and adjusts the carrying device from the first height to the second height, wherein the second height is higher than the first height. Then, after the carrier device is adjusted to the second height, the water level sensor will continue to sense the water level change around the vehicle and return to step S405. In other words, if the water level around the vehicle is maintained at or above the second threshold, the carrier will remain at the second level.

In step S407, the lifting device performs a lowering action and adjusts the carrying device To the first height. Next, the water level sensor continues to sense the water level change around the vehicle, and returns to step S402. Then, the water level sensor senses whether the water level reaches the first threshold to further determine whether to adjust the height of the carrying device again.

In addition, the intelligent water level detection method can also be performed together with a warning method. In detail, when the smart water level detecting method is in execution and the pressure sensor senses the movement of the vehicle, the wireless module of the intelligent water level detecting system outputs a warning signal to the lifting device, so that the lifting device The alarm module drives the LED flashing and drives the buzzer to sound an alarm.

In an embodiment of the invention, a light sensor can be used to assist in sensing whether the vehicle enters the carrier. That is to say, when both the pressure sensor and the light sensor sense that the vehicle enters the carrying device, the smart water level detecting system automatically executes the smart water level detecting method, and proceeds to step S402. In addition, a light sensor can also be used to assist in determining whether the vehicle is moving abnormally. For example, when the smart water level detecting method is in the process of execution, the pressure sensor senses the movement of the vehicle, and the light sensor senses the brightness change, the wireless module of the intelligent water level detecting system will The warning signal is output to the lifting device, so that the alarm module of the lifting device drives the LED to flash and the buzzer is sounded.

According to the above, the intelligent water level detecting system and the method thereof according to the embodiments of the present invention can automatically detect the water level change around the vehicle, and adjust the height of the carrying device correspondingly according to the water level change. Compared with the existing outdoor parking lot, the embodiment of the invention can solve the problem that the vehicle becomes a water tanker because the road area water is too high. In addition, the intelligent water level detecting system and the method provided by the embodiments of the present invention can be combined with the warning function to provide a more secure parking service for the vehicle owner.
