Abstract
Description
Technical Field
[0001] This utility model relates to the field of water pump control and display technology, and in particular to a novel water pump control and display circuit. Background Technology
[0002] Current water pump control displays mostly use digital tube display technology, which has the following drawbacks:
[0003] 1. Simple display function: The digital tube can only display numbers (0-9) and a few simple letters (such as AF), and cannot intuitively display dynamic working status. For example, it cannot present graphs, dynamic curves or real-time data of multiple parameters (such as flow rate, pressure and temperature displayed at the same time). Users need to switch the display content through buttons or codes. Users need to operate frequently to obtain complete status information, which is inefficient and prone to errors.
[0004] 2. The configuration is not intuitive: the operation interface is complex, parameter adjustment relies on numerical codes or simple symbols, and there is a lack of intuitive menus or icon guidance, which makes it difficult for non-professionals to operate.
[0005] 3. Production inconvenience: The alarm needs to be placed externally on the equipment casing, involving additional wiring and fixing steps, extending the production cycle, and increasing assembly difficulty and cost. Moreover, external connections are susceptible to environmental factors such as vibration and humidity, leading to poor contact or an increased failure rate.
[0006] Therefore, there is an urgent need for a water pump control display screen that features dynamic display, intuitive configuration, and high production and assembly efficiency. Utility Model Content

[0035] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0036] Reference Figure 1, in an exemplary embodiment, a novel water pump control display circuit is provided, including:
[0037] A control main board, including a single-chip microcomputer, is connected to the water pump and is used to control the display and alarm of the water pump;
[0038] A segment code liquid crystal display screen is connected to the single-chip microcomputer through a display driving circuit and is used to dynamically display the working state of the water pump;
[0039] An alarm module integrated on the control main board is connected to the single-chip microcomputer and is used to trigger an alarm after receiving a water pump alarm signal.
[0040] A power conversion module is connected to the single-chip microcomputer and the display driving circuit and is used to convert the externally input power supply.
[0041] The display driving circuit of the segment code liquid crystal display screen includes a driving chip and peripheral components. The driving chip includes a dedicated chip for segmented liquid crystal, such as Figure 2 shown. This chip supports up to 128 segment codes, a 3-wire serial interface (SPI compatible), a working voltage of 2.4V - 5.2V, adjustable driving current, simple interface, and low cost, and is suitable for dynamic display requirements.
[0042] As Figure 3 shown, the single-chip microcomputer uses an ARM core 32-bit single-chip microcomputer. The single-chip microcomputer circuit forms a control core to control display and alarm. The single-chip microcomputer sends display data and display logic signals to the driving chip, and the driving chip controls the segment code liquid crystal display screen for display. Specifically, it is connected to the driving chip through the corresponding pins of MCU-LED-LIGHT.
[0043] The alarm module includes a driving transistor and a buzzer connected in sequence. The state of the water pump is fed back to the single-chip microcomputer through a sensor. The single-chip microcomputer judges whether the water pump is running normally according to the data of the sensor. If a fault or abnormality occurs, a fault signal and a linkage signal are sent to the alarm module, and the alarm module emits an alarm sound. As Figure 4 shown, the alarm module can perform linkage alarm. Specifically, when a water pump fails, it triggers other associated devices or systems to take coordinated actions, such as triggering a valve to close when the water pump fails, notifying the upper computer system, etc. Usually, a fault code is prompted through a sound and light signal (buzzer, LED flashing) or a display screen. Combining Figure 2 , Figure 3 it can be known that the linkage alarm signal is sent to the driving chip through the pin corresponding to MCU - WR1 on the single-chip microcomputer. The driving chip accesses the signal through the pin VLCD1 and displays the linkage information through the segment code liquid crystal display screen.
[0044] Figure 5As shown, the alarm module can also provide fault alarms. When the water pump malfunctions (such as overload, excessive temperature, abnormal pressure, short circuit, etc.), a local alarm is triggered to remind operators to immediately troubleshoot and repair the fault, preventing equipment damage or safety accidents. Fault codes are typically displayed via audible and visual signals (buzzer, LED flashing) or a screen, combined with... Figure 2 , Figure 3 As can be seen, the linkage alarm signal is sent to the driver chip through the corresponding pin of MCU-WR2 on the microcontroller. The driver chip receives the signal through pin VLCD2 and displays the fault alarm information on the segment LCD screen.
[0045] Preferably, the driving transistor is an NPN transistor, and the buzzer is a passive piezoelectric ceramic buzzer.
[0046] like Figures 6-7 As shown, the power conversion module includes a switching regulator and a level conversion chip connected in sequence. The switching regulator converts an externally supplied 12V power supply to 5V, and then the level conversion chip converts the 5V power supply to 3.3V to power the components on the mainboard. Preferably, the switching regulator is a non-isolated DC-DC buck converter, and the level conversion chip is a TTL level converter.
[0047] The above detailed embodiments are a detailed description of the present utility model. It should not be considered that the specific embodiments of the present utility model are limited to these descriptions. For those skilled in the art, several simple deductions and substitutions can be made without departing from the concept of the present utility model, and all of these should be considered to fall within the protection scope of the present utility model.
