[0002] During the use of the car, the expansion tank and brake fluid tank of the coolant in the car play a vital role in the normal use of the car. In the use requirements of the car, the driver is required to check the fluid level before using the car. If the fluid level is below the qualified line, it needs to be replenished to above the qualified line (below the maximum value) before using the car.

[0003] However, during normal use of the car, users will not or forget to observe the liquid levels of the antifreeze expansion tank and the brake fluid tank, which can easily lead to malfunctions during driving and cause traffic accidents.

Inaccurate liquid level measurement may easily cause the car to malfunction during use.

[0005] Therefore, in order to ensure the safety of automobile use, it is necessary to provide an intelligent system that can monitor the liquid level in the automobile liquid tank. Summary of the invention

[0006] Based on this, an object of the present invention is to provide an intelligent liquid level monitoring system capable of monitoring liquid level.

[0037] like Figure 1 As shown, the present invention relates to an intelligent liquid level monitoring system, comprising a liquid level monitoring device 1 for monitoring the change of the liquid level in a monitored container 100, a data processing module 2 for receiving and processing the signal sent by the liquid level monitoring device 1, and a prompting module 3 for receiving the signal of the data processing module 2 and prompting the user of the liquid level situation in the monitored container 100; the data processing module 2 comprises a judgment unit for judging the signal sent by the liquid level monitoring device 1; the liquid level monitoring device 1 is communicatively connected to the judgment unit, and the judgment unit is communicatively connected to the prompting module 3.

[0038] In the present invention, the liquid level change in the monitored container 100 is monitored by the liquid level monitoring device 1, and the signal of the liquid level change is transmitted to the data processing module 2 for analysis and processing. Thereafter, the data processing module 2 sends the analyzed and processed signal to the prompt module 3 to prompt the user of the liquid level in the monitored container 100, so that when the liquid level in the monitored container 100 is low, the user can discover and replenish it in time to avoid safety problems caused by the low liquid level in the monitored container 100; at the same time, the signal sent by the liquid level monitoring device 1 is judged and analyzed by the judgment unit to eliminate the liquid level changes caused by external factors, so that the user can obtain the most accurate liquid level of the monitored container 100.

[0039] The judgment unit includes one or more of a liquid level change frequency judgment subunit 21 , a liquid level change amplitude judgment subunit 22 , a temperature judgment subunit 23 , and a time point judgment subunit 24 .

[0040] The liquid level change frequency judgment subunit 21, the liquid level change amplitude judgment subunit 22 and the temperature judgment subunit 23 are all connected to the liquid level monitoring device 1 and the prompt module 3 in communication. During the use of the monitored container 100, it may be affected by external vibration or temperature, causing the liquid level in the monitored container 100 to change continuously, and the precise liquid level of the monitored container 100 cannot be known. Therefore, through the setting of the liquid level change frequency judgment subunit 21, the liquid level change amplitude judgment subunit 22, the temperature judgment subunit 23 and the time point judgment subunit 24, when the liquid level change frequency in the monitored container 100 is less than the preset value of the liquid level change frequency, when the liquid level change amplitude in the monitored container 100 is less than the preset value of the liquid level change amplitude, when the liquid temperature in the monitored container 100 is less than the preset value of the liquid level temperature, and within the time interval from a predetermined time after the car is turned off to before the car is started again, the judgment unit sends a valid signal to the prompt module 3 to ensure the accuracy of the data received by the user.

[0041] In this embodiment, one or more combinations of the liquid level change frequency judgment subunit 21, the liquid level change amplitude judgment subunit 22, the temperature judgment subunit 23 and the time point judgment subunit 24 can be selected to work together. When multiple subunits are working and multiple judgment subunits receive valid signals, multiple judgment subunits send data to the prompt module 3; when any seed unit is judged as an invalid signal, no signal is sent to the prompt module 3, so as to ensure the accuracy of the data received by the prompt module 3.

[0042] The prompt module 3 includes a terminal 31 that is communicatively connected to the data processing module 2, and the terminal 31 includes one or more of a PC, a smart phone, a smart wearable device, a car instrument, and a vehicle-mounted control display screen, so as to facilitate sending a monitoring report of the monitored container 100 to the user; the monitoring report can be information such as the liquid level and liquid temperature in the monitored container 100, and can also display the urgency of the liquid level situation of the monitored container 100 to the user, so as to facilitate the user to deal with the liquid level situation in the monitored container 100 in a timely manner to avoid safety problems or damage to the monitored container 100.

[0044] In other embodiments, the prompt module 3 includes an alarm unit 32 that is communicatively connected to the data processing module 2. The alarm unit 32 can be a buzzer or a warning light. It can be reasonably selected according to the specific needs of the user, ensuring that the user can be informed in time after the liquid level of the monitored container 100 is in an emergency, thereby avoiding subsequent safety problems.

[0045] In this embodiment, the judgment unit sends a signal to the prompt module 3 via WIFI, Bluetooth, 4G or 5G mobile communication, etc., to ensure the timeliness of the information through remote transmission; and the judgment unit can have a unique ID number to have an encryption effect during remote transmission.

[0046] In other embodiments, the judgment unit may also be connected to the prompt module in a wired communication manner.

[0047] Combination Figure 2 and Figure 3 As shown, the liquid level monitoring system 1 includes a guide structure 11 vertically arranged on the side wall of the monitored container 100, a float 12 movable along the guide structure 11, and a sensor 13 for sensing the float 12; in this embodiment, the sensor 13 is preferably a Hall proximity sensor, and the float 12 is preferably a magnetic float; the sensor 13 is communicatively connected to the judgment unit of the data processing module 2.

[0048] The float 12 can move along the guide structure 11 according to the change of the liquid level, and can be sensed by the sensor 13 to obtain the liquid level in the monitored container 100 .

[0049] In this embodiment, the guide structure 11 is preferably a liquid guide tube disposed on the side wall of the monitored container 100, the float 12 is cylindrical, and the float 12 is disposed in the liquid guide tube, and the upper and lower parts of the liquid guide tube are both provided with openings 14, and the liquid guide tube is connected to the monitored container 100 through the openings 14. In other embodiments, the sensor 13 can be selected from other inductive sensors that can be used to sense the float 12.

[0050] The liquid catheter can be arranged on the inner wall of the monitored container 100, and the sensor 13 can be arranged on the outer wall of the monitored container 100; the liquid catheter can also be arranged on the outer wall of the monitored container 100, and the sensor 13 can be arranged on the outer wall of the liquid catheter; the liquid catheter and the monitored container 100 are integrally formed.

[0051] The upper and lower parts of the liquid conduit are both provided with openings 14 that are connected to the monitored container 100, so that the position of the float 12 in the liquid conduit relative to the liquid conduit can change with the change of the liquid level in the monitored container 100. The outer wall of the liquid conduit is provided with a sensor 13 for sensing the position of the float 12, so that the liquid level of the monitored container 100 can be monitored.

[0052] In other embodiments, the guide structure 11 can also be a guide column arranged on the inner wall of the monitored container 100, the float 12 is in a circular ring shape, the float 12 is sleeved on the outer periphery of the guide column, and can move along the guide column, and the sensor 13 is arranged on the outer wall of the monitored container 100 to sense the float 12; the guide column and the monitored container 100 are integrally formed.

[0053] In this embodiment, a plurality of sensors 13 are provided, and the plurality of sensors 13 are arranged along the height direction of the guide structure 11 to improve the monitoring intensity of the liquid level situation in the monitored container 100, and more accurately grasp the liquid level situation in the monitored container 100, so as to facilitate the user to take timely measures according to the liquid level situation in the monitored container 100 and avoid subsequent safety problems.

[0054] In this embodiment, the plurality of sensors 13 are evenly distributed along the height direction of the liquid guiding tube, thereby dividing the liquid level in the monitored container 100 into different conditions, so that the user can accurately grasp the liquid level condition in the monitored container 100.

[0055] In other embodiments, the plurality of sensors 13 are arranged in an arithmetic progression, so that when the liquid level of the monitored container 100 is in a critical situation, it is more convenient for the user to be informed of the critical situation of the liquid level in the monitored container 100. For example, the user receives liquid level information more and more frequently, so as to prompt the user to add corresponding liquid to the monitored container 100 as soon as possible.

[0056] In other embodiments, the liquid level monitoring device 1 includes a capacitive liquid level sensor or an ultrasonic sensor arranged outside the monitored container 100, and both the capacitive liquid level sensor and the ultrasonic sensor are communicatively connected to the data processing module 2 to monitor the liquid level of the monitored container 100.

[0057] In this embodiment, the monitored container 100 may be an expansion tank and a brake fluid tank of a car coolant to ensure the driving safety of the user. In other embodiments, the intelligent liquid level monitoring system may also be used in other containers whose liquid levels need to be monitored.

[0058] The present invention also relates to a monitoring method of an intelligent liquid level monitoring system, which is applied to the above-mentioned intelligent liquid level monitoring system and comprises the following steps:

[0059] S1. The liquid level monitoring device 1 monitors the liquid level of the monitored container 100 and transmits the signal of the liquid level change to the data processing module 2 for analysis and processing;

[0060] S2. The data processing module 2 receives and processes the liquid level change signal of the liquid level monitoring device 1 to obtain an accurate liquid level change, and transmits the processed liquid level change signal to the prompt module 3;

[0061] S3. The prompt module 3 receives the signal from the data processing module 2 and reminds the user of the liquid level in the monitored container 100;

[0062] Wherein, the data processing module 2 includes a judgment unit for judging the accuracy of liquid level change.

[0063] In the monitoring method of the intelligent liquid level monitoring system of the present invention, the liquid level change signal of the liquid level monitoring device 1 is judged by the judgment unit to determine whether the liquid level change signal of the liquid level monitoring device 1 is valid, and the valid signal is transmitted to the prompt module 3 to ensure that the data received by the user is highly accurate.

[0064] In this embodiment, the judgment unit includes one or more of a liquid level change frequency judgment subunit 21, a liquid level change amplitude judgment subunit 22, a temperature judgment subunit 23, and a time point judgment subunit 24;

[0065] The liquid level change frequency judgment subunit 21 is in communication connection with the liquid level monitoring device 1, and is used to judge the accuracy of the liquid level change of the monitored container 100 according to the frequency of the liquid level change. When the liquid level change frequency of the monitored container 100 is greater than the preset value of the liquid level change frequency, the liquid level change signal monitored by the liquid level monitoring device 1 is judged to be an invalid signal. Otherwise, a valid signal is sent to the prompt module 3.

[0066] The liquid level change amplitude judgment subunit 22 is in communication connection with the liquid level monitoring device 1, and is used to judge the accuracy of the liquid level change of the monitored container 100 according to the liquid level change amplitude. When the liquid level change amplitude of the monitored container 100 is greater than the preset value of the liquid level change amplitude, the liquid level change signal monitored by the liquid level monitoring device 1 is judged to be an invalid signal; otherwise, a valid signal is sent to the prompt module 3;

[0067] The temperature judgment subunit 23 is in communication connection with the liquid level monitoring device 1, and is used to judge the accuracy of the liquid level change of the monitored container 100 according to the liquid temperature in the monitored container 100. When the liquid temperature in the monitored container 100 is greater than the preset value of the liquid temperature in the monitored container 100, the liquid level change signal monitored by the liquid level monitoring device 1 is judged to be an invalid signal; otherwise, a valid signal is sent to the prompt module 3;

[0068] The time point judgment unit 24 is communicatively connected with the liquid level monitoring device 1, and is used to judge the accuracy of the liquid level change of the monitored container 100 according to the time interval. In the time interval from a predetermined time after the car is turned off to before the car is started again, the liquid level change signal monitored by the liquid level monitoring device 1 is judged to be a valid signal, and the valid signal is sent to the prompt module; in other time intervals, it is judged to be an invalid signal.

[0069] By setting the time point judgment unit 24, the liquid level information received by the user is the liquid level information when the liquid level is less affected by temperature and vibration conditions after the car is turned off, which is beneficial to the accuracy of liquid level monitoring.

[0070] In this embodiment, the time point judgment unit 24 can determine that the liquid level signal monitored by the liquid level monitoring device 1 is a valid signal within the time interval from one hour after the car is turned off to before the car is started again. In other embodiments, the starting point of the time interval determined by the time point judgment unit 24 as a valid signal is two hours, three hours, etc. after the car is turned off. The time interval can be reasonably set according to the user's vehicle model or other conditions to ensure the accuracy of monitoring.

[0071] In this embodiment, when the judgment unit includes at least two judgment sub-units, all the judgment sub-units in the judgment unit determine that the signals they receive are valid signals, and then transmit the signals to the prompt module 3; as long as one of the judgment sub-units in the judgment unit receives an invalid signal, the judgment unit does not send a signal to the prompt module 3 to ensure that the data received by the prompt module 3 is accurate.

[0072] Alternatively, in other embodiments, among all judgment subunits in the judgment unit, except for the judgment subunit that receives an invalid signal, other judgment subunits that receive a valid signal all send the valid signal to the prompt module 3 for user reference.

[0073] In summary, compared with the prior art, on the first aspect, the monitoring method of the intelligent liquid level monitoring system of the present invention filters out invalid signals detected by the liquid level monitoring device 1 due to external factors, so that the user can obtain the accurate liquid level in the monitored container 100 and ensure subsequent safety; on the second aspect, the user does not need to observe the liquid level in the monitored container 100 with the naked eye, thereby avoiding the failure of the monitored container when it is working due to not knowing how to check or forgetting to check the liquid level of the monitored container 100, thereby affecting safety; on the third aspect, the intelligent liquid level monitoring system can send a signal to remind the user to replenish the liquid in the monitored container 100 to prevent omissions and ensure safety.

[0074] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
