Description

Technical Field

[0001] This invention relates to the field of equipment control technology, and in particular to a method, apparatus, equipment, and storage medium for detecting the status of a feed line. Background Technology

[0002] During the feeding process, the main or auxiliary feed line may experience problems such as large foreign objects falling into the feed line, feed clumping, feed inlet not opening, or feed inlet blockage. As a result, the feed accumulates more and more in the feed pipe, the load on the feed chain increases, and eventually the feed pipe becomes completely blocked or the feed chain breaks.

[0003] Currently, to prevent complete blockage of the feed pipe and chain breakage, the decision to stop the feed line is made by detecting whether the maximum current in the feed line drive motor is within the protection range. As the chain load increases, the maximum current in the drive motor also increases. However, this solution can only ensure that the condition of the feed pipe and chain does not deteriorate further. Usually, by the time the maximum current is detected to exceed the protection range, the condition of the feed pipe and chain is already very serious, making it difficult to clear the blockage and relieve the pressure on the chain. Furthermore, the current detection method has a long response time, low sensitivity, and is easily affected by external voltage, making it impossible to accurately predict and respond to the condition of the feed pipe and chain in advance.

[0004] Therefore, there is an urgent need for a method to detect the condition of the feed line that can improve the sensitivity and accuracy of feed line and chain jamming detection. Summary of the Invention

[0005] This invention provides a method, apparatus, device, and storage medium for detecting the state of a feed line, in order to solve the technical problem of low sensitivity and accuracy in the detection of feed lines and plug chains in the prior art.

[0006] To address the aforementioned technical problems, embodiments of the present invention provide a method for detecting the state of a material production line, comprising:

[0007] The system collects the on / off signal of the discharge valve at the junction between material lines and determines the state of the discharge valve based on the on / off signal; the state of the discharge valve includes a closed state and an open state.

[0008] If it is in the closed position, the signal from the probe at the end of the feed line is collected, and the fullness of the feed inside the feed line is determined based on the signal from the probe at the end of the feed line. Then, based on the fullness and the state of the feed valve, the current operating status of the feed line is detected.

[0009] If it is in the fully open state, the limit switch signal of the chain in the material line is collected, and the tension state of the chain is determined according to the limit switch signal. Thus, the current operating state of the discharge line is detected according to the state of the discharge valve and the tension state of the chain.

[0010] The current operating status of the discharge line includes normal operating status and abnormal operating status.

[0011] As a preferred embodiment, the method involves collecting the on / off signal of the discharge valve at the transition point between material lines, and determining the state of the discharge valve based on the on / off signal, specifically as follows:

[0012] Collect and determine the on / off state signals of the feed valve at the transition point between material lines; wherein, the on / off state signals include an open state signal and a closed state signal, the open state signal is generated when the feed valve is fully open, and the closed state signal is generated when the feed valve is fully closed;

[0013] If the signal is "open to position", then the discharge valve is in the "open to position" state;

[0014] If the signal is closed, the discharge valve is in the closed state.

[0015] As a preferred embodiment, the signal from the probe at the end of the feed line is collected, and the feed filling level inside the feed line is determined based on the signal from the probe at the end of the feed line. Then, based on the feed filling level and the status of the discharge valve, the current operating status of the feed line is detected. Specifically:

[0016] The distance between the feed line and the feed is detected by the probe at the end of the feed line. When the distance is less than a preset value, a full feed signal is generated.

[0017] When the generated full feed signal is collected, the feed inside the feed line is in a full feed state;

[0018] When the feed line is full and the feed valve is closed, the current operating state of the feed line is detected as abnormal, and an abnormal operating alarm for feed line blockage is generated.

[0019] As a preferred embodiment, before the on / off signal of the discharge valve at the transfer point between the material collection lines, the following is also included:

[0020] The current value of the drive motor of the feeding line is collected, and the current operating status of the feeding line is detected based on the current value and the preset current protection range.

[0021] If the current value exceeds the preset current protection range and continues for a preset time, the current operating state of the material line is detected as abnormal, and the operation of the material line is stopped.

[0022] As a preferred embodiment, the limit switch signal of the feed conveyor belt in the collection line is used to determine the tension state of the feed conveyor belt based on the limit switch signal, specifically as follows:

[0023] The limit switch signal of the feeder chain in the feed line is collected by means of the limit switch of the feeder chain; wherein the limit switch is disposed on both sides of the feeder chain;

[0024] If the limit switch signal is in the open state, the chain is in a taut state;

[0025] If the limit switch signal is in the off state, the chain is in a relaxed state.

[0026] As a preferred embodiment, the step of detecting the current operating status of the discharge line based on the status of the discharge valve and the tension status of the plug chain specifically involves:

[0027] When the plug chain is in a relaxed state and the feed valve is in the fully open state, it is detected that the feed line is currently in normal operation.

[0028] When the feeder chain is in a taut state and the feed valve is in the fully open state, the abnormal operation of the feed line is detected, and an abnormal operation alarm indicating that the feeder chain is about to break is generated.

[0029] Accordingly, the present invention also provides a material line status detection device, comprising: a feeding valve status module, a first execution module, and a second execution module;

[0030] The feed valve status module is used to collect the on / off signal of the feed valve at the junction between material lines, and to determine the status of the feed valve based on the on / off signal; the status of the feed valve includes a closed state and an open state.

[0031] The first execution module is used to collect the signal from the probe at the end of the feed line if it is in the closed position, and determine the fullness of the feed inside the feed line based on the signal from the probe at the end of the feed line, thereby detecting the current operating status of the feed line based on the fullness and the status of the discharge valve.

[0032] The second execution module is used to collect the limit switch signal of the chain in the material line if it is in the open position, and determine the tension state of the chain according to the limit switch signal, so as to detect the current running state of the discharge line according to the state of the discharge valve and the tension state of the chain.

[0033] The current operating status of the discharge line includes normal operating status and abnormal operating status.

[0034] Accordingly, the present invention also provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, characterized in that the processor, when executing the computer program, implements the method for detecting the state of the feed line as described in any of the preceding claims.

[0035] Accordingly, the present invention also provides a computer program product that, when run on a terminal device, causes the terminal device to execute the material line status detection method as described in any of the above claims.

[0036] Compared with the prior art, the embodiments of the present invention have the following beneficial effects:

[0037] The technical solution of this invention uses the on / off signal of the feed valve at the junction between feed lines to determine the status of the feed valve. By monitoring the status of the feed valve, the fullness of the feed line or the tension of the chain can be detected, thus revealing the current operating status of the feed line. This invention avoids the problems of slow response and low accuracy caused by detecting parameters of the external motor, such as the maximum current inside the drive motor. By detecting the actual feed fullness and chain tension inside the feed line, the detection response speed and efficiency are improved. Furthermore, the acquisition of actual parameters inside the feed line enhances detection accuracy. Attached Figure Description

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example 1

[0043] Please refer to Figure 1 The present invention provides a method for detecting the state of a feed line, comprising the following steps S101-S103:

[0044] Step S101: Collect the switch position signal of the feed valve at the junction between material lines, and determine the state of the feed valve based on the switch position signal; the state of the feed valve includes the closed position and the open position.

[0045] It should be noted that you should refer to [link / reference]. Figure 2 The feed line consists of a main feed line and auxiliary feed lines. The main feed line receives feed from the feed tower and transfers it to the corresponding feed valve, discharging the feed from the main feed line into the auxiliary feed lines. The auxiliary feed lines are used to transport feed to different storage sheds. The connection between the main feed line and each auxiliary feed line is the feed valve, which controls the flow of feed from the main feed line to the auxiliary feed lines. When the feed line controller opens the feed valve, a feedback signal is generated indicating whether the valve is fully open or fully closed. If the feed valve is fully open, an open signal is provided; if it is fully closed, a closed signal is provided.

[0046] In a preferred embodiment, the opening / closing signal of the discharge valve at the junction between material lines is collected, and the state of the discharge valve is determined based on the opening / closing signal. Specifically:

[0047] The system collects and determines the on / off state signals of the discharge valve at the transition point between material lines; wherein the on / off state signals include an open state signal and a closed state signal, the open state signal is generated when the discharge valve is fully open, and the closed state signal is generated when the discharge valve is fully closed; if it is an open state signal, the discharge valve is in the open state; if it is a closed state signal, the discharge valve is in the closed state.

[0048] It should be noted that the feed valve's open / closed position signal is provided by a feedback signal when the feed line controller opens the valve. If the feed valve is fully open, an open position signal is provided; if the feed valve is fully closed, a closed position signal is provided. The open position signal of the feed valve connecting the main and auxiliary feed lines is also checked. If no open position signal is detected on the feed valve during feed line operation, it indicates that the feed is not being fed normally into the auxiliary feed line, which is highly likely to cause a blockage. Therefore, it is determined that there may be an abnormal feed supply in the feed line, and the feed valve will be in the closed position.

[0049] As a preferred embodiment, before the on / off signal of the unloading valve at the transfer point between the material collection lines, the following is further included:

[0050] The current value of the drive motor of the feeding line is collected, and the current operating status of the feeding line is detected based on the current value and the preset current protection range. If the current value exceeds the preset current protection range and continues for a preset time, the current operating status of the feeding line is detected as abnormal operation, and the operation of the feeding line is stopped.

[0051] It should be noted that, based on the current value of the drive motor during the material feeding operation, a rated current value (or a preset current protection range) is set. When the current value of the drive motor of the material feeding line is greater than the rated current value (or exceeds the preset current protection range) and continues for a period of time (to prevent false judgment), the material feeding of the material feeding line is judged to be abnormal, the material feeding line is controlled to stop running, and an alarm is issued.

[0052] In this embodiment, since the existing technology usually uses the current value of the drive motor of the feeding line to determine the operating status of the feeding line, the detection sensitivity of the current value is not high. Therefore, when the current value detection has a problem, it means that the current system has an abnormal situation. When the current value detection has no problem, the current system may not have an abnormal situation, or it may have an abnormal situation. Therefore, using the current value detection as a judgment condition for the pre-detection can efficiently and accurately detect the operating status of the feeding line and the chain conveyor.

[0053] Step S102: If it is in the closed position, the signal of the probe at the end of the feed line is collected, and the fullness of the feed inside the feed line is determined according to the signal of the probe at the end of the feed line. Then, the current operating status of the discharge line is detected according to the fullness and the status of the discharge valve. The current operating status of the discharge line includes normal operating status and abnormal operating status.

[0054] In a preferred embodiment, the signal from the probe at the end of the feed line is collected, and the feed filling level inside the feed line is determined based on the signal from the probe at the end of the feed line. Then, based on the feed filling level and the state of the discharge valve, the current operating state of the feed line is detected. Specifically:

[0055] The distance between the feed line and the feed is detected by the probe at the end of the feed line. When the distance is less than a preset value, a full feed signal is generated. When the generated full feed signal is collected, it is determined that the feed line is full. When the feed line is full and the feed valve is closed, the current operating state of the feed line is detected as abnormal, and an abnormal operating alarm for feed line blockage is generated.

[0056] In this embodiment, when the feed valve is in the closed position, it indicates that the feed line may be full, causing blockage of the feed valves between the feed lines. This prevents feed from being properly fed to the auxiliary feed line, resulting in the feed valve not detecting the open position signal. Therefore, it is necessary to acquire the full feed probe signal to determine if the feed line supply is abnormal. When a full feed probe signal is detected in the main feed line or auxiliary feed line, indicating that the main feed line or auxiliary feed line is full, the feed line is stopped and an alarm is issued.

[0057] Understandably, a full feed probe can detect whether the feed line is full, thus accurately determining whether there is a blockage or other abnormality. Preferably, the full feed probe can be a distance sensor probe such as an infrared sensor, ultrasonic sensor, or lidar. It is usually set at the end of the feed line, that is, the end away from the main feed line. Therefore, by measuring the distance between the feed in the feed line and itself, it is possible to detect whether the feed line is full.

[0058] Step S103: If it is in the fully open state, the limit switch signal of the chain in the material line is collected, and the tension state of the chain is determined according to the limit switch signal. Thus, the current operating state of the discharge line is detected according to the state of the discharge valve and the tension state of the chain.

[0059] In a preferred embodiment, the step of collecting the limit switch signal of the feeder chain in the material line and determining the tension state of the feeder chain based on the limit switch signal specifically involves:

[0060] The limit switch signal of the chain in the material line is collected by means of the limit switch of the chain; wherein the limit switch is set on both sides of the chain; if the limit switch signal is in the open state, the chain is in a taut state; if the limit switch signal is in the closed state, the chain is in a slack state.

[0061] In this embodiment, if the feed valve is in the fully open state, it means that the feed lines are connected. In order to avoid the feed from becoming difficult to flow in the feed line due to the gradual accumulation of feed during the feeding process, it is necessary to detect the status of the feed line blockage to determine whether the feed line is in a normal working state.

[0062] It should be noted that the feed chain is mainly used to propel the feed forward within the feed line. Next to the feed chain is a limit switch. When the feed chain reaches a certain tension, it actuates the limit switch, causing it to switch contacts and trigger a circuit opening / closing signal. The feed chain's structure is similar to a looped rubber band. When the chain is slack, it cannot actuate the switch; when taut, it clamps the switch, causing it to open and close, thus actuating the contacts. Therefore, the limit switch signal from the feed line feed chain can be used to detect abnormal feed supply. When a signal is detected on the limit switch of the feed line feed chain in the main or auxiliary feed line, it indicates a high load on the feed chain and a potential breakage. In this case, the feed line will stop running, and an alarm will be triggered.

[0063] In a preferred embodiment, the step of detecting the current operating status of the discharge line based on the state of the discharge valve and the tension state of the plug chain specifically involves:

[0064] When the feed chain is in a relaxed state and the discharge valve is in the fully open state, the feed line is detected to be in normal operation. When the feed chain is in a taut state and the discharge valve is in the fully open state, the feed line is detected to be in abnormal operation and an abnormal operation alarm indicating that the feed chain is about to break is generated.

[0065] Understandably, detecting the status of the chain blockage can reduce the risk of chain breakage, while improving the accuracy and sensitivity of blockage detection. It enables highly sensitive detection of the material line's condition, reducing the risk of blockage, ensuring normal material supply, extending the material line's lifespan, increasing production efficiency, and providing timely alarms for abnormal material supply, allowing for manual intervention and prevention.

[0066] Implementing the above embodiments has the following effects:

[0067] The technical solution of this invention uses the on / off signal of the feed valve at the junction between feed lines to determine the status of the feed valve. By monitoring the status of the feed valve, the fullness of the feed line or the tension of the chain can be detected, thus revealing the current operating status of the feed line. This invention avoids the problems of slow response and low accuracy caused by detecting parameters of the external motor, such as the maximum current inside the drive motor. By detecting the actual feed fullness and chain tension inside the feed line, the detection response speed and efficiency are improved. Furthermore, the acquisition of actual parameters inside the feed line enhances detection accuracy.

[0068] Example 2

[0069] Please see Figure 3 It is a material line status detection device, including: a feeding valve status module 201, a first execution module 202, and a second execution module 203.

[0070] The feed valve status module 201 is used to collect the switch position signal of the feed valve at the junction between material lines, and to determine the status of the feed valve based on the switch position signal; the status of the feed valve includes a closed position and an open position.

[0071] The first execution module 202 is used to collect the signal from the end probe of the feed line if it is in the closed position, and determine the fullness of the feed inside the feed line based on the signal from the end probe of the feed line, thereby detecting the current operating status of the feed line based on the fullness and the status of the feed valve.

[0072] The second execution module 203 is used to collect the limit switch signal of the chain in the material line if it is in the open position, and determine the tension state of the chain according to the limit switch signal, so as to detect the current running state of the discharge line according to the state of the discharge valve and the tension state of the chain.

[0073] In a preferred embodiment, the opening / closing signal of the discharge valve at the junction between material lines is collected, and the state of the discharge valve is determined based on the opening / closing signal. Specifically:

[0074] The system collects and determines the on / off state signals of the discharge valve at the transition point between material lines; wherein the on / off state signals include an open state signal and a closed state signal, the open state signal is generated when the discharge valve is fully open, and the closed state signal is generated when the discharge valve is fully closed; if it is an open state signal, the discharge valve is in the open state; if it is a closed state signal, the discharge valve is in the closed state.

[0075] In a preferred embodiment, the signal from the probe at the end of the feed line is collected, and the feed filling level inside the feed line is determined based on the signal from the probe at the end of the feed line. Then, based on the feed filling level and the state of the discharge valve, the current operating state of the feed line is detected. Specifically:

[0076] The distance between the feed line and the feed is detected by the probe at the end of the feed line. When the distance is less than a preset value, a full feed signal is generated. When the generated full feed signal is collected, it is determined that the feed line is full. When the feed line is full and the feed valve is closed, the current operating state of the feed line is detected as abnormal, and an abnormal operating alarm for feed line blockage is generated.

[0077] As a preferred embodiment, before the on / off signal of the unloading valve at the transfer point between the material collection lines, the following is further included:

[0078] The current value of the drive motor of the feeding line is collected, and the current operating status of the feeding line is detected based on the current value and the preset current protection range. If the current value exceeds the preset current protection range and continues for a preset time, the current operating status of the feeding line is detected as abnormal operation, and the operation of the feeding line is stopped.

[0079] In a preferred embodiment, the step of collecting the limit switch signal of the feeder chain in the material line and determining the tension state of the feeder chain based on the limit switch signal specifically involves:

[0080] The limit switch signal of the chain in the material line is collected by means of the limit switch of the chain; wherein the limit switch is set on both sides of the chain; if the limit switch signal is in the open state, the chain is in a taut state; if the limit switch signal is in the closed state, the chain is in a slack state.

[0081] In a preferred embodiment, the step of detecting the current operating status of the discharge line based on the state of the discharge valve and the tension state of the plug chain specifically involves:
