[0047] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0048] In an exemplary embodiment, the embodiment of the present application provides a liquid leakage detection system. As Figure 1 shown, the system includes: a control module, a processing module, and a plurality of detection devices, where:

[0049] The detection device is used to detect the status signal of the target object on the transmission device and send the status signal.

[0050] The control module is used to receive the status signals sent by each detection device, and generate a control instruction and output the control instruction when it is determined that the status signal is an abnormal signal. The abnormal signal is a status signal that meets the preset liquid leakage detection condition.

[0051] The processing module is used to receive the control instruction sent by the control module and execute the liquid leakage processing operation corresponding to the control instruction.

[0052] Among them, the status signal can reflect whether the liquid of the target object drips onto the detection device. The preset liquid leakage detection condition can be that the status signal exceeds the preset status, and the preset status signal threshold can be determined according to the actual application environment. The preset liquid leakage condition can also be determined according to the correspondence between the status signal and the liquid leakage state. For example, the status signal of 1 corresponds to the liquid leakage state, and the status signal of 0 corresponds to the normal state.

[0053] Specifically, the detection device can transmit data to the control module in a wired manner. The control module can communicate with the processing module in a wired manner and perform data interaction. The transmission device can be a conveyor belt. The detection device can be a detection board. The detection device can be arranged below the transmission device, and the target object is placed above the transmission device. The conveyor belt can be composed of chains. When there is liquid leakage in the target object, the leaking object can drip through the chains onto the corresponding detection board, causing the status signal on the detection device to change.

[0054] Multiple sensors can be arranged on each detection device. When the target object on the transmission device passes by the detection device, the detection device can detect the status signal of the target object through the sensors. The number of detection devices can be determined according to the length of the transmission device and the actual application scenario, and no specific limitation is provided here.

[0055] The control module can receive the status signals sent by each detection device in real time or after reaching a certain preset cycle duration. Alternatively, when each detection device detects a change in the status signal, it transmits the status signal to the control device in real time. For example, the status signal changes from 0 to 1, or from 1 to 0.

[0056] The control module can detect whether each status signal meets the preset liquid leakage detection condition. If it detects that a status signal exceeds the preset status signal threshold, it determines that the status signal meets the preset liquid leakage condition and determines this status signal as an abnormal signal. The control module can also, based on the correspondence between the status signal and the liquid leakage state, if the status signal corresponds to the liquid leakage state, determine that the status signal meets the preset liquid leakage detection condition and determine this status signal as an abnormal signal.

[0057] When the status signal is determined to be an abnormal signal, the control module can generate a control instruction and output the control instruction to the processing module.

[0058] The processing module can receive the control instruction sent by the control module, and the processing module can execute the liquid leakage handling operation corresponding to the control instruction. The liquid leakage handling operation can include but is not limited to removing the target object with liquid leakage, cleaning the liquid leakage on the detection device, adjusting the running speed of the transmission device, and so on.

[0059] In the above liquid leakage detection system, the status signal of the target object is detected by the detection device, and the control module determines the status signal that meets the preset liquid leakage condition as an abnormal signal, generates a corresponding control instruction based on the abnormal signal, and sends the control instruction to the processing module. The processing module can execute the liquid leakage handling operation corresponding to the control instruction, which can timely detect the target object with liquid leakage and perform timely processing on the target object with liquid leakage, improving the detection efficiency, as well as the production efficiency and production quality, and ensuring the safety of the production and transportation processes.

[0060] In an exemplary embodiment, multiple detection devices are respectively installed at preset positions on the transmission device. The preset positions are determined according to the liquid leakage frequency at each position on the transmission device and / or the risk position information of the transmission device. Each detection device is composed of multiple sensors.

[0061] Among them, the leakage frequency at each position on the transmission device can be statistically calculated based on the historical data of the position information where leakage occurs on the transmission device and the number of leakage times corresponding to each position information. The risk position information of the transmission device can be determined according to the actual operating environment of the transmission device and its design, to identify high-risk positions where leakage may occur. For example, the high-risk positions may include positions on the transmission device that are prone to jitter, etc. The preset position can be the position information on the transmission device corresponding to a leakage frequency greater than the frequency threshold. The preset position can also be determined based on the risk position information. The preset position can also be comprehensively determined based on the leakage frequency and the risk position information.

[0062] Specifically, each detection device can be installed below the transmission device. The size of the detection device can be determined based on the actual size of the transmission device, and the positions of the detection devices do not overlap. The control module can pre-store the position information corresponding to each detection device and the number information of the detection device corresponding to each position information.

[0063] Multiple sensors can be arranged on each detection device. The types of sensors on each detection device can be the same or different. The types of sensors can be the same type or an arrangement combination of multiple different types of sensors. When the target object on the transmission device passes through the detection device, the detection device can detect the state signal of the target object through the sensors, and this state signal can reflect whether the liquid of the target object drips onto the detection device. For example, the state signal can at least include one or more of the humidity value of the detection board and the pressure value on the detection board detected by the sensors. The state signal can also be in the form of a digital signal. For example, 0 indicates no leakage, and 1 indicates there is leakage.

[0064] The control module can receive the status signals sent by each detection device in real time or within a preset period. The control module can detect whether each status signal meets the liquid leakage detection condition. If it is detected that there is a status signal greater than the liquid leakage detection condition, it is determined that the status signal meets the preset liquid leakage condition, and the status signal is determined as an abnormal signal. In the case of determining that the status signal is an abnormal signal, the control module can generate a control instruction and output the control instruction to the processing module. For example, the status signal is the humidity value on the detection board. When the humidity value is greater than the preset humidity value, it is determined that the status signal meets the preset liquid leakage condition, and it is determined that the target object has a liquid leakage. The status signal is the pressure value of the detection board. When the pressure value is less than the preset pressure value, it is determined that the status signal meets the preset liquid leakage condition, and it is determined that the target object has a liquid leakage; the status signal can also include the humidity value and the pressure value. The control module can comprehensively determine whether the target object has a liquid leakage based on the humidity value and the pressure value. If the humidity value is greater than the preset humidity value and the pressure value is less than the preset pressure value, it is determined that the status signal meets the preset liquid leakage condition, and it is determined that the target object has a liquid leakage. It should be understood that the examples here are only for explanation and do not constitute specific limitations.

[0065] In this embodiment, multiple detection devices are respectively installed at preset positions, which improves the utilization efficiency of the detection devices and the accuracy of detecting liquid leakage.

[0066] In an exemplary embodiment, as Figure 2 shown, the control module can specifically include a controller and a relay;

[0067] The controller is used to receive the status signals sent by each detection device, and judge whether the status signals meet the preset liquid leakage detection condition. If the status signals meet the preset liquid leakage condition, it is determined that the status signals are abnormal signals, and a trigger signal is generated based on the abnormal signals, and the trigger signal is sent to the relay;

[0068] The relay is used to determine the position information of the liquid leakage of the target object based on the number information, generate a control instruction based on the position information and the trigger signal, and send the control instruction to the processing module.

[0069] Among them, the trigger signal carries the number information of the abnormal detection device. The control instruction can reflect the execution operation on the corresponding processing module.

[0070] Specifically, the controller can receive the status signals sent by each detection device in real time or after a certain preset cycle duration. The controller can determine whether the status signal meets the preset liquid leakage detection condition. If the status signal exceeds the preset status signal threshold, it is determined that the status signal meets the preset liquid leakage condition, and the status signal is determined to be an abnormal signal. The controller can identify the number information of the detection device carried by the abnormal signal. The controller can generate a trigger signal based on the abnormal signal and carry the number information of the detection device corresponding to the abnormal signal on the trigger signal. The controller sends the trigger signal carrying the number information to the relay.

[0071] The relay can determine the position of the target detection device corresponding to the number information in the correspondence between the number information and the position information of the detection device. The position of the target detection device is the position information where the target object has liquid leakage. The relay can generate a corresponding control instruction based on the position information and the trigger signal. The relay can send the control instruction to the corresponding processing module.

[0072] In an exemplary embodiment, as Figure 2 shown, the processing module includes an alarm unit;

[0073] The alarm unit is used to perform an alarm prompt operation based on the control instruction.

[0074] Among them, the control instruction can carry parameters related to the alarm, such as the abnormal signal. The alarm prompt operation is used to prompt that the target object has liquid leakage and the position of the target object with liquid leakage. The alarm prompt operation includes but is not limited to one or more of voice reminder, light reminder, and remote reminder.

[0075] Specifically, the alarm unit can receive the control instruction sent by the relay in a wired manner. The alarm unit can respond to the abnormal signal carried in the control instruction and can determine the position of the transmission device where the abnormality occurs.

[0076] In this embodiment, the alarm unit performs an alarm prompt operation to prompt the user that the target object has liquid leakage to ensure the safety of the user and remind the user to respond to the abnormal signal in time.

[0077] In an exemplary embodiment, as Figure 2 shown, the processing module further includes a cleaning unit;

[0078] The cleaning unit is used to perform a cleaning operation based on the control instruction.

[0079] Among them, the cleaning operation is used to clean the position where the liquid leakage occurs on the transmission device based on the control instruction and the position information. The cleaning unit can be arranged beside the detection device.

[0080] Specifically, the cleaning unit can receive the control instructions sent by the relay in a wired manner. The cleaning unit can move the cleaning unit to the position information indicated by the control instructions based on the control instructions, and the cleaning unit can clean the target detection device corresponding to the position information based on the control instructions.

[0081] In addition, the liquid leakage detection system can further include a clamping device. The clamping device can receive the control instructions sent by the controller, and determine the target position of the target object based on the position information indicated by the control instructions, and move the target object with liquid leakage out of the transmission device through the target position.

[0082] In this embodiment, the transmission device at the liquid leakage position is cleaned by the cleaning unit to facilitate the subsequent operation of the transmission device.

[0083] In an exemplary embodiment, as Figure 2 shown, the system further includes a reset module;

[0084] The control module is further configured to generate a reset control instruction and output the reset control instruction if no abnormal signal is detected within a preset interval duration;

[0085] The reset module is configured to receive the reset control instruction sent by the control module and restore the system to the initial state based on the reset control instruction.

[0086] Among them, the initial state can be the preset state of the liquid leakage detection system, or the state of the liquid leakage detection system before the control module detects the abnormal signal. The reset control instruction can include the initial state information of each module in the liquid leakage detection system. The preset interval duration can be determined according to the actual application scenario, such as 10 minutes.

[0087] Specifically, the control signal can store the moment value when the abnormal signal is detected. If no next abnormal signal is detected within the preset interval duration, it indicates that there is no target object with liquid leakage on the transmission device, and a reset control instruction is generated and sent to the reset module. The reset module receives the reset control instruction sent by the control module, and sends reset indication information to the processing module and / or the transmission control module based on the reset control instruction. The processing module and / or the transmission control module restore each unit in the module to the initial state after receiving the reset indication information.

[0088] Exemplarily, the reset module can restore the processing module to the initial state, such as turning off the alarm prompt of the alarm unit or restoring the cleaning unit to the initial position, etc. The reset module can also restore the transmission speed of the transmission device to the initial speed, etc.

[0089] In addition, if an abnormal signal is still detected within a preset interval duration, the control module continues to perform corresponding processing based on the abnormal signal, improving the safety after restarting the system.

[0090] The liquid leakage detection system can also be externally provided with a reset button. The reset module can also receive trigger information. If the trigger information is received, it responds to the trigger information and restores each module to its initial state. The trigger information is formed when the reset button on the reset module is triggered. If the control module still receives an abnormal signal, the reset module does not respond to the trigger information even if it receives the trigger information.

[0091] In this embodiment, by determining that no abnormal signal is detected within a preset interval duration, the liquid leakage detection system is restored to its initial state, and the normal operation of the system is restored.

[0092] In an exemplary embodiment, as Figure 2 shown, the system further includes a transmission control module; the transmission control module is configured to receive a control instruction sent by the control module and adjust the transmission speed of the transmission device based on the control instruction.

[0093] Among them, the transmission control module can be a Programmable Logic Controller (PLC) module.

[0094] Specifically, when the transmission control module receives a control instruction sent by the control module and the control instruction is that the status signal is an abnormal signal, it adjusts the transmission speed of the transmission device to 0.

[0095] In addition, the transmission control module can also stop the operation of the palletizer based on the control instruction.

[0096] In this embodiment, according to the abnormal signal, the transmission speed of the transmission device is adjusted to an appropriate transmission speed, ensuring the safety of the transmission device and reducing the risk of failure when an abnormality occurs.

[0097] In one embodiment, the application scenario of the liquid leakage detection system provided by the embodiments of the present application can be applied not only to the liquor production field but also to other fields that require detection of liquid leakage.

[0098] In an exemplary embodiment, a liquid leakage detection method provided by the embodiments of the present application can be applied to a liquid leakage detection system as Figure 1 shown. As Figure 3 shown, the method may include the following steps:

[0099] Step 301, detect the status signal of the target object on the transmission device through each detection device and send the status signal.

[0100] Step 302: Receive the status signals sent by each detection device through the control module, generate a control instruction when it is determined that the status signal is an abnormal signal, and output the control instruction.

[0101] Step 303: Receive the control instruction sent by the control module through the processing module, and perform the liquid leakage treatment operation corresponding to the control instruction.

[0102] Among them, the status signal can reflect whether the liquid of the target object drips onto the detection device. The preset liquid leakage detection condition can be that the status signal exceeds the preset status signal threshold, etc., and the preset status signal threshold can be determined according to the actual application environment. The preset liquid leakage condition can also be determined according to the correspondence between the status signal and the liquid leakage state. For example, the status signal of 1 corresponds to the liquid leakage state, and the status signal of 0 corresponds to the normal state.

[0103] Specifically, the detection device can transmit data to the control module in a wired manner. The control module can communicate with the processing module in a wired manner and perform data interaction. The transmission device can be a conveyor belt.

[0104] Multiple sensors can be arranged on each detection device. When the target object on the transmission device passes through the detection device, the detection device can detect the status signal of the target object through the sensors.

[0105] The control module can receive the status signals sent by each detection device in real time or after reaching a certain preset cycle duration. The control module can detect whether each status signal meets the preset liquid leakage detection condition. If it is detected that a status signal exceeds the preset status signal threshold, it is determined that the status signal meets the preset liquid leakage condition, and the status signal is determined as an abnormal signal. When it is determined that the status signal is an abnormal signal, the control module can generate a control instruction and output the control instruction to the processing module.

[0106] The processing module can receive the control instruction sent by the control module, and the processing module can perform the liquid leakage treatment operation corresponding to the control instruction. The liquid leakage treatment operation can include but is not limited to removing the target object with liquid leakage, cleaning the liquid leakage on the transmission device, adjusting the running speed of the transmission device, etc.

[0107] The above liquid leakage detection method can detect the status signal of the target object through the detection device, determine the status signal that meets the preset liquid leakage condition as an abnormal signal through the control module, generate a corresponding control instruction based on the abnormal signal, send the control instruction to the processing module, and the processing module can perform the liquid leakage treatment operation corresponding to the control instruction. It can timely detect the target object with liquid leakage and perform timely processing on the target object with liquid leakage, improve the detection efficiency, and also improve the production efficiency and production quality, ensure the safety of the production and transportation processes, and improve the user experience.

[0108] In one embodiment, the liquid leakage detection method may specifically include the following steps:

[0109] The controller receives the status signals of each detection device in real time. When an abnormal signal is detected in the status signals, it is determined that the target object has a liquid leakage. The controller generates a trigger signal and sends it to the relay. The relay receives the trigger signal, generates a control instruction based on the trigger signal, and outputs the control instruction. The alarm unit can receive the control instruction and send an alarm prompt signal. The PLC system can receive the control instruction sent by the relay and, based on the control instruction, stop the operation of the conveyor belt and / or the palletizer. The cleaning unit can receive the control instruction sent by the relay and, based on the control instruction, remove the target object with liquid leakage and clean the liquid leakage on the conveying device. If the control module does not receive the next abnormal signal within a preset interval duration, it generates a reset control instruction and outputs the reset control instruction. The reset module receives the reset control instruction sent by the control module and restores the normal operation of the system based on the reset control instruction.

[0110] In this embodiment, by monitoring the liquid leakage situation in real time, the problem of liquor explosion can be discovered and handled in time, reducing the occurrence of safety accidents and ensuring the normal operation of the production line. Moreover, the detection accuracy is high, which can avoid false alarms and ensure the normal operation of the transportation line. All modules need to meet the corresponding specifications and model requirements to ensure the normal operation of the system. All operations need to be carried out in strict accordance with the operation procedures to ensure safety and accuracy. The liquid leakage detection system forms a complete automated production line, improving production efficiency and production quality and meeting modern requirements. The embodiments of the present application have broad application prospects in the fields of liquor production, logistics transportation, and automation control.
