Description

Technical Field

[0001] The present invention relates to the technical field of peristaltic pump management, and in particular to a peristaltic pump water outlet control method and system. Background Art

[0002] Peristaltic pumps pump fluids by alternately squeezing and releasing the elastic delivery hose, just like pinching the hose with two fingers. As the fingers move, negative pressure is formed in the hose, and the liquid flows. Using peristaltic pumps to drive liquid flow output is a common application in industry. It is widely used in the fields of liquid pipeline transportation and pipeline cleaning. In order to ensure the working effect of the peristaltic pump, the peristaltic pump is required to accurately discharge water and inject liquid.

[0003] In order to ensure the accuracy of water discharge and injection of peristaltic pumps, flow sensors are traditionally used to detect the volume of liquid flowing in the pipeline, and whether the peristaltic pump continues to work is determined based on the liquid volume. However, the following problems exist: 1. When the liquid flows through the pipeline, it is often affected by factors such as the rotation speed of the peristaltic pump, the liquid flow rate, and the flow volume, which makes it impossible for the liquid to fill the entire pipeline, causing a certain error in the detection feedback of the flow sensor, and there is a certain lag in controlling the operation of the peristaltic pump through the detection data of the flow sensor, which in turn affects the injection accuracy of the peristaltic pump; 2. No security measures are taken for the transmission of relevant data. When the data of the flow sensor is tampered with, it will directly affect the operation of the peristaltic pump, which may cause siltation and blockage in the pipeline, posing a huge safety hazard.

[0004] Therefore, how to provide a peristaltic pump water outlet control method and system to improve the injection accuracy and safety of the peristaltic pump water outlet control has become a technical problem that needs to be solved urgently. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a peristaltic pump water outlet control method and system to improve the injection accuracy and safety of the peristaltic pump water outlet control.

[0006] In a first aspect, the present invention provides a peristaltic pump water outlet control method, comprising the following steps:

[0007] Step S1, the server calibrates the peristaltic pump through a metering device to obtain a water output volume parameter of the peristaltic pump;

[0008] Step S2: the server obtains a liquid injection target value, and calculates the number of rotations of the peristaltic pump based on the liquid injection target value and the water output volume parameter;

[0009] Step S3: the server encrypts the number of rotations into ciphertext data, generates a water outlet control instruction based on the ciphertext data, and sends the water outlet control instruction to the controller;

[0010] Step S4: the controller receives the water outlet control instruction, verifies the water outlet control instruction, and decrypts the ciphertext data carried by the water outlet control instruction to obtain the number of rotations;

[0011] Step S5: The controller controls the peristaltic pump to perform a water outlet operation based on the number of rotations.

[0016] Perform hash calculation on the ciphertext data to obtain a hash value, obtain the current timestamp and device serial number, generate a water outlet control instruction based on the ciphertext data, hash value, timestamp and device serial number, and send the water outlet control instruction to the controller via the TLS protocol.

[0017] Furthermore, the step S4 is specifically as follows:

[0018] The controller receives the water outlet control instruction in real time through the wireless communication module, parses the water outlet control instruction to obtain ciphertext data, hash value, timestamp and device serial number, verifies the legitimacy of the device serial number through the preset device management table, verifies the timeliness through the timestamp, and then verifies the integrity of the ciphertext data through the hash value;

[0019] The controller decrypts the ciphertext data through the RC2 algorithm to obtain a fourth character string, maps the fourth character string through a preset mapping rule to obtain a third character string, decrypts the third character string through the AES algorithm to obtain a second character string, divides the second character string based on the inverse of a preset division ratio and swaps the order to obtain a first character string, and decrypts the first character string through the El Gama l algorithm to obtain the number of rotations.

[0020] Furthermore, the step S5 further includes:

[0021] During the operation of the peristaltic pump, the controller records in real time a work log including at least the operating time, the number of starts and stops, the actual number of rotations, the installation location, and the length of time in use. After encrypting the work log into an encrypted log, the encrypted log is uploaded to the server for archiving via the TLS protocol.

[0022] In a second aspect, the present invention provides a peristaltic pump water outlet control system, comprising the following modules:
