Description

Technical Field

[0001] This invention relates to the field of peristaltic pump control and status monitoring technology, and in particular to a peristaltic pump hose cumulative timing and active alarm system and its working method. Background Technology

[0002] In the peristaltic pump industry, the vast majority of pump heads use flexible hoses to transfer fluids. These hoses are made of materials such as silicone, PVC, thermoplastic elastomers, and fluororubber. Regardless of the type of hose, repeated rolling by rollers can cause fatigue damage. Hose damage can lead to leaks, contamination of the transported medium, and corrosion of equipment, resulting in economic losses. If the liquid is toxic, it may also cause harm to human health. To avoid and reduce the impact of hose damage, this software module was designed. It records the hose usage time in real time and automatically alarms when a set time limit is reached, reminding the user to replace the hose.

[0003] Hose timing, combined with leak sensors and AI big data, enables integrated automation of prevention and control. When several devices use the same model of pump head and hose, if a pump head triggers a leak sensor alarm, the backend server records the hose usage time and then checks if other pump heads are approaching or exceeding that time and issuing an alarm, allowing for timely hose replacement to avoid the risk of breakage. Summary of the Invention

[0004] The purpose of this invention is to provide a peristaltic pump hose cumulative timing and active alarm system and its working method, which can accurately count the actual usage time of the hose and actively alarm after the life limit is exceeded, monitor hose leakage and operating status in real time, and realize multi-device linkage early warning based on big data to achieve automated active protection.

[0010] Preferably, the remote communication module adopts the Modbus485 communication protocol.

[0011] A method for operating a peristaltic pump hose cumulative timing and active alarm system includes the following steps: Step S1: Lifetime parameter preset; Input the hose lifetime setting value through the parameter setting module; Step S2: Pump head status monitoring; The pump head status detection module monitors in real time whether the pump head is in operation. Step S3: Synchronous timing and comprehensive detection; If the pump head is detected to be running, the timing module continuously accumulates the cumulative usage time of the hose, and at the same time, the auxiliary detection module and the leakage sensor are started to carry out detection work synchronously. Step S4: Time threshold comparison; The comparison module determines in real time whether the cumulative usage time of the hose exceeds the hose life setting value; Step S5: Cyclic status detection; If the cumulative usage time has not exceeded the hose life setting value, return to step S2 and continue to cyclically detect the pump head operation status.

Detailed Implementation

[0018] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] Unless otherwise defined, the technical or scientific terms used in this invention shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0020] The terms "first," "second," and similar words used in this invention do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0021] Example 1 like Figures 1-6 As shown, this invention discloses a peristaltic pump hose cumulative timing and active alarm system, comprising a parameter setting module, a pump head status detection module, a timing module, a comparison module, an auxiliary detection module, an alarm module, a leakage sensor, a remote communication module, and a backend server. The parameter setting module receives and stores user-inputted hose life settings. The module includes an input unit and a storage unit. The input unit is used to input hose life values, and the storage unit is a non-volatile storage unit. This ensures that the hose life settings are permanently saved and the data is not lost after power failure.

[0022] Operators input parameters via a touchscreen interface, setting lifespan values ​​based on the hose material used on-site. The lifespan setting ranges from 0 to 1000 hours. Standard silicone hoses can be set to 100 hours, while imported fluororubber hoses can be set to a maximum of 1000 hours. After inputting the value, clicking "confirm" automatically saves it to the storage unit; the parameters are retained even after power outages or restarts. The parameter setting module also integrates a timer reset function; after replacing the hose, operators can reset the historical accumulated time to zero using this function.

[0023] The pump head status detection module is used to monitor the operating status of the peristaltic pump head in real time and output a status signal. The module employs a current sampling detection circuit, connected in series in the power supply circuit of the peristaltic pump drive motor, and consists of a sampling resistor, an operational amplifier, and a signal conditioning circuit. The module collects the motor's operating current in real time, pre-sets a current threshold, and determines that the pump head is in operation when the motor is running normally and the current exceeds the threshold, outputting a high-level signal to the timing module. When the motor stops and the current falls below the threshold, the module determines that the pump head has stopped operating and outputs a low-level signal. The pump head status detection module only judges the actual start-stop status of the pump head, eliminating interference from invalid states such as no-load and standby, ensuring that the timing data accurately reflects the actual rolling wear time of the hose.

[0024] The timing module is electrically connected to the pump head status detection module. It receives pump head operation signals and continuously accumulates hose usage time during pump head operation. The timing module relies on the microcontroller's internal hardware timer to implement the timing function. It only starts timing when it receives a high-level signal indicating pump head operation, and the accumulated time is synchronized to the touch screen for display in real time. When it receives a low-level stop signal, the timing immediately pauses and locks the current accumulated value. The timing resumes when the pump head restarts.

[0025] The comparison module is electrically connected to the parameter setting module and the timing module respectively, and is used to compare and judge the cumulative usage time of the hose with the hose life setting value in real time.

[0026] The comparison module uses the microcontroller's built-in logic to perform data comparison, reading the hose life setpoint and real-time cumulative time every second and performing numerical judgment. The comparison module is also electrically connected to the pump head status detection module. When the comparison module determines that the cumulative usage time has not exceeded the hose life setpoint, it sends a signal to the pump head status detection module, causing the system to continuously execute the pump head status detection process. If the cumulative usage time does not exceed the life setpoint, it sends a loop signal to the pump head status detection module, causing the system to continuously execute the pump head status detection process; if the cumulative usage time exceeds the life setpoint, it immediately outputs a timeout trigger signal to the alarm module.

[0027] The auxiliary detection module is electrically connected to the timing module and is used to start synchronously during pump head operation, sequentially performing pressure detection, flow rate detection, and motor torque detection. Each detection unit is equipped with a flow stabilization and rectification structure and a digital filtering processing mechanism to counteract the interference of periodic pulsations in the peristaltic pump fluid and ensure the accuracy of detection and judgment.

[0028] The auxiliary detection module includes a pressure detection unit, a flow rate detection unit, and a motor torque detection unit, which are electrically connected in sequence. Data acquisition and anomaly detection are performed in a fixed-cycle polling manner. After the pump head starts, the auxiliary detection module runs in parallel with the timing process, continuously monitoring the status throughout the entire operating cycle of the pump head.

[0029] The pressure detection unit uses an industrial pressure sensor and is installed in the buffer pipeline section downstream of the pump head outlet. A pulse damper or buffer cavity is installed on the pipeline between the pump head outlet and the pressure sensor to suppress the periodic pressure pulsation of the fluid output by the peristaltic pump. At the same time, the pressure detection unit is connected to the system microcontroller signal and uses a digital filtering algorithm of moving average and amplitude limiting to smooth the sampled data and obtain a stable effective value of fluid pressure for subsequent anomaly detection.

[0030] The flow velocity detection unit employs a turbine flow velocity sensor, positioned in the middle section of the fluid delivery pipeline. Straight pipe straightening sections conforming to metrological specifications are installed on both the inlet and outlet sides of the turbine flow velocity sensor. The length of these straight pipe sections is no less than 10 times the nominal diameter of the sensor, used to regulate the flow field and reduce the impact of fluid pulsations on the impeller. Flow velocity detection data is calculated by taking the arithmetic mean of multi-cycle sampling, using the average flow velocity per unit time as the detection basis to offset pulsation fluctuations within a single cycle, ensuring stable and reliable detection values.

[0031] The motor torque detection unit is used to detect the output load torque of the pump head drive motor, and can be implemented in, but is not limited to, the following two forms: Direct measurement solution: A strain gauge torque sensor is used and mounted on the output shaft of the drive motor to directly collect the actual output torque at the shaft end. It has high detection accuracy and is suitable for scenarios requiring high-precision monitoring.

[0032] Indirect estimation scheme: When the drive motor is a low-speed constant current chopper controlled stepper motor, a sampling resistor is connected in series in the drive circuit of each phase winding of the stepper motor to collect the winding current waveform in real time. After signal conditioning by operational amplifier and quantization by analog-to-digital converter, the signal is transmitted to the system microcontroller. Combined with the torque constant Kt of the stepper motor, the estimated value of the current output torque is obtained. No additional mechanical sensing components are required, which is simple to implement and has a low cost. It can meet the needs of coarse torque monitoring, stall detection and overload detection.

[0033] The system has preset anomaly detection criteria: fluid pressure below 70% of normal operating pressure, fluid flow velocity fluctuation exceeding ±20%, and motor output torque below 75% of normal torque. Meeting any one of these conditions indicates an abnormal hose condition. These anomaly thresholds are significantly larger than the fluid pulsation fluctuation amplitude under normal peristaltic pump operation (normal pressure pulsation amplitude not exceeding ±10% of the nominal value, and normal flow velocity pulsation amplitude not exceeding ±15% of the nominal value). Combined with the aforementioned flow stabilization structure and filtering, interference from normal pulsation on anomaly detection can be completely eliminated. An alarm is only triggered when the hose experiences aging, damage, internal leakage, or other faults causing significant parameter deviations. If any item in a single round of testing is deemed abnormal, an anomaly signal is immediately output to the alarm module without waiting for the completion of other testing items.

[0034] The three detection units operate in strict sequence: pressure detection, flow rate detection, and motor torque detection. The next detection is started only after the previous one is completed. If any detection is found to be abnormal, an abnormal signal is immediately output to the alarm module.

[0035] Leak sensors are deployed around the hose to detect leaks in real time and output leak alarm signals. Several sets of leak sensors are distributed below the hose, at the pump head base, and in areas prone to leakage in the pipeline, serving as direct detection components for hose damage. The leak sensors continuously sense the presence of leaking fluid in the surrounding area. Once a leak is detected, a leak alarm signal is immediately output to both the alarm module and the remote communication module, enabling rapid on-site detection of hose damage and leaks.

[0036] The alarm module is electrically connected to the comparison module, the auxiliary detection module, and the leakage sensor, and is used to issue an alarm when the cumulative usage time exceeds the life set value, the auxiliary detection result is abnormal, or the leakage sensor detects a leak.

[0037] The alarm module includes a display alarm unit and a sound alarm unit, which are configured in three forms: text prompt, sound prompt, and combined text and sound prompt. For different fault types, corresponding prompt pop-up windows will appear on the touch screen: when the duration limit is exceeded, it shows "Exceeded time limit for hose use"; when the parameter is abnormal, it shows "Abnormal hose status"; when leakage occurs, it shows "Hose leakage, please repair immediately"; the buzzer emits continuous alarm sounds synchronously according to the preset mode to remind on-site operation and maintenance personnel to handle the fault.

[0038] The remote communication module is electrically connected to the timing module, the liquid leakage sensor, and the alarm module respectively, and is used for uploading local data and alarm signals and receiving remote instructions.

[0039] The remote communication module adopts the Modbus485 communication protocol to achieve two-way data interaction between local devices and the background server. The remote communication module is the data interaction hub between the local terminal and the background server, and is bidirectionally electrically connected to the timing module, the liquid leakage sensor, and the alarm module. During operation, the module transmits the cumulative hose duration, pump head operation status, and various alarm signals upwards in real time; at the same time, it receives the cluster warning instructions and remote parameter modification instructions issued by the background server and forwards them to the corresponding function modules.

[0040] The background server is communicatively connected to the remote communication module and is equipped with AI big data analysis function, which is used to receive the data and alarm signals uploaded by several peristaltic pumps and establish an equipment database. When receiving a liquid leakage alarm signal, it records the actual service life of the corresponding hose, retrieves the remaining devices in the database that use the same type of pump head and the same specification of hose, and issues a warning instruction to the devices whose cumulative hose duration is close to or exceeds the actual service life.

[0041] An industrial cloud server is adopted and deployed in the plant central control room, equipped with AI big data analysis software and an equipment database. The basic information of all networked peristaltic pumps is uniformly entered into the database, including pump head model, hose material, hose specification, preset life, real-time cumulative duration, historical fault records, etc. The AI big data program has functions of data storage, intelligent retrieval, life statistics, and linkage warning. After receiving the liquid leakage alarm signal uploaded by the local terminal, it automatically records the actual service life of the hose when it is damaged. And with "pump head model and hose specification" as the retrieval condition, it batch-screens all devices with the same configuration in the database to complete risk level determination and warning instruction issuance. The background server and all local terminals establish a long connection through the Modbus485 protocol to achieve all-time data intercommunication.

[0042] A working method for cumulative timing and active alarm of a peristaltic pump hose includes the following steps: Step S1: Lifespan parameter preset; input the hose lifespan setting value through the parameter setting module; after the equipment is powered on and the system is initialized, the operator enters the corresponding lifespan setting value (0-1000 hours) according to the hose material on site through the touch screen interface of the parameter setting module. After confirmation, the parameter is automatically saved. For example, if a silicone hose is used to transport conventional media, the lifespan is set to 100 hours.

[0043] Step S2: Pump head status monitoring; The pump head status detection module monitors in real time whether the pump head is in operation. The system enters normal monitoring mode, and the pump head status detection module continuously collects motor current and continuously monitors the pump head's start-stop status.

[0044] Step S3: Synchronous Timing and Comprehensive Detection; If the pump head is detected to be running, the timing module continuously accumulates the hose's cumulative usage time, while simultaneously activating the auxiliary detection module and leak sensor to perform detection. The operator starts the peristaltic pump, and the pump head operates normally. The pump head status detection module outputs a high-level operating signal to the timing module; the timing module begins to continuously accumulate the hose's cumulative usage time. At the same time, the auxiliary detection module and leak sensor are activated synchronously, running in parallel with the timing process to perform real-time pipeline parameter detection and leak monitoring. If the pump is temporarily stopped during operation, the timing module immediately pauses timing and retains the current value, automatically resuming accumulation upon restarting the pump head.

[0045] In step S3, the timing module only accumulates time when the pump head is running; when the pump head stops running, the timing work is paused and the current accumulated time is saved, and the timing continues to accumulate when the pump head is restarted.

[0046] In step S3, the detection process of the auxiliary detection module and the leakage sensor and the timing process of the timing module are executed in parallel and run continuously throughout the entire operating cycle of the pump head.

[0047] Step S4: Duration Threshold Comparison; The comparison module determines in real time whether the cumulative usage time of the hose exceeds the hose lifespan setting. The comparison module reads the cumulative duration and the preset lifespan value every second, performs data comparison, and determines whether the hose usage time exceeds the limit.

[0048] Step S5: Cyclic status detection; if the cumulative usage time has not exceeded the hose life setting value, return to step S2 and continue to cyclically detect the pump head operation status.

[0049] Step S6: Timeout alarm prompt; if the cumulative usage time exceeds the hose life setting value, the alarm module will issue a timeout alarm prompt.

[0050] Step S7: Execution of auxiliary detection process and alarm; if any of the detection results of pressure detection, flow rate detection, or motor torque detection is abnormal, or if the leakage sensor detects a hose leak, an alarm will be triggered directly; during stand-alone operation, the remote communication module will upload the cumulative hose duration, equipment status, and various alarm signals to the backend server in real time.

[0051] In step S7, an alarm is triggered immediately when any abnormal signal is generated, without waiting for the remaining detection items to be completed.

[0052] When several peristaltic pumps are operating in a network on site, and some of the equipment uses the same model of pump head and the same specification of hose, the cluster linkage early warning function is activated. The specific procedure is as follows: When the leak sensor of a peristaltic pump in the cluster detects a hose leak and triggers an alarm, the device uploads the leak alarm signal and the current cumulative usage time of the hose to the backend server via the remote communication module; the backend server records the actual service life of the hose when fatigue failure occurs.

[0053] The backend server starts an AI big data analysis program, using "pump head model, hose material, and hose specifications" as search criteria, to traverse the equipment database and filter out all peristaltic pump devices in the cluster that use the same pump head and hose.

[0054] The backend server compares the cumulative usage time of the hoses of each device. For devices whose cumulative usage time is close to or exceeds the actual service life of the aforementioned damaged hoses, an early warning command is issued via the remote communication module. Upon receiving the command, the local terminal's alarm module issues a hose replacement warning, reminding maintenance personnel to replace the hoses in advance and preventing mass hose damage incidents from the source.

[0055] Therefore, the present invention adopts the above-mentioned peristaltic pump hose cumulative timing and active alarm system and working method, which completely solves the defects of traditional peristaltic pumps that rely on manual experience to judge the hose replacement time, lack leak monitoring, and cannot link multiple devices for protection, and realizes automated monitoring and active protection of the hose throughout its entire life cycle.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention; and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
