BRIEF DESCRIPTION OF DRAWINGS

[0015] The following is a brief description of the contents and symbols in the drawings of the present invention:

[0016] Figure 1 This is a structural principle diagram of the shipborne water pump intelligent monitoring system of the present utility model. DETAILED DESCRIPTION

[0017] The specific implementation of the present invention will be further explained in detail below by describing the best embodiment with reference to the accompanying drawings.

[0018] This embodiment mainly designs a control system for a shipboard water pump used on a ship. Through this system, the water pump can be controlled to work on demand, reducing energy consumption. At the same time, the working status of the water pump can be monitored, thereby improving the monitoring effect of the ship. The specific scheme is as follows:

[0019] like Figure 1 As shown, an intelligent control system for shipborne water pumps is shown, the shipborne water pumps include cooling system water pumps, and the control system includes a temperature sensor, a microprocessor, a PWM controller, an IoT chip, and a remote monitoring platform; the temperature sensor is used to collect temperature data of the object acted on by the cooling system, and its output end is connected to the microprocessor; the microprocessor controls the operating speed of the cooling system water pump according to the temperature data, and its output end is connected to the PWM controller; the PWM controller outputs a corresponding PWM signal to the cooling system water pump based on the control signal of the microprocessor to control the speed of the water pump; the microprocessor is connected to the IoT chip, and is connected to the remote monitoring platform through the IoT chip, and is used to upload the monitored working status data of the shipborne water pump to the remote monitoring platform.

[0020] Wherein since there are various types of ship-mounted water pumps, for the cooling system water pump, its speed can be adjusted by temperature to reduce the noise and waste of energy consumption of the cooling system water pump, and to achieve on-demand control; the temperature sensor monitors the temperature of the object of the cooling system, such as the temperature of the heating part of the power battery, and the temperature data is sent to the microprocessor, which has simple data processing and control functions, such as commonly used 51 single-chip microcomputer, DSP processor, etc. The microprocessor judges whether the speed of the water pump should be adjusted up or down according to the temperature and outputs the corresponding speed control signal to the PWM controller, which is a control chip that can output PWM duty cycle signal. The PWM signal output from the output end of the PWM controller acts on the ship-mounted water pump, thereby controlling the speed of the ship-mounted water pump and achieving precise control. Since the speed of the water pump is adjusted according to the temperature demand, the speed adjustment is more accurate and reliable, and the energy waste caused by the mismatch between the speed and the demand is reduced. Since the cooling of the power battery of the electric ship is not important, the temperature of the water pump needs to be monitored and the working state of the water pump needs to be understood, so the working state and the monitored data of the water pump need to be remotely monitored, and therefore an IoT chip is provided for uploading information. The data is uploaded to the remote monitoring platform through the IoT chip for monitoring and viewing. The remote server or cloud platform performs centralized storage and management, and the platform can use computers, mobile phones, servers, etc. to realize viewing and storage management, etc.

[0021] In a preferred embodiment, the monitoring data required by the monitoring platform not only includes basic data such as speed and temperature, but also includes working state data of the water pump, so a monitoring sensor is arranged on the ship, which is used to monitor the operating parameters of the ship-mounted water pump, and its output end is connected to the microprocessor; the microprocessor regulates the ship-mounted water pump based on the monitored operating parameters or uploads the operating data of the ship-mounted water pump to the remote monitoring platform through the IoT chip. The monitoring sensor includes a pressure sensor, a flow sensor, and a working voltage and current sensor; the pressure sensor is used to collect water pressure data at the water inlet of the water pump, and its output end is connected to the microprocessor; the flow sensor is used to collect the flow of the water pump at the outlet of the water pump, and its output end is connected to the microprocessor; the working voltage and current sensor is used to collect the working voltage and current data of the water pump, and its output end is connected to the microprocessor. The monitored water pressure, flow, working voltage and current data of the water pump can be used to judge the working state of the water pump and make adaptive adjustment of the speed, and even can judge whether the water pump is malfunctioning, and at the same time the data can be uploaded to the remote monitoring platform for processing, realizing remote monitoring and processing.

[0022] In a preferred embodiment, the ship-mounted water pump includes a main and standby water pump, and the microprocessor is connected to the main and standby water pump respectively and controls one of them to work. The main and standby water pumps are controlled by the microprocessor, that is, the microprocessor is connected to the main and standby water pump respectively through the PWM controller, and by default, the microprocessor controls the main water pump to work and the standby water pump not to work; when it is judged according to the signal collected by the monitoring sensor that the main water pump has an abnormal work, the standby water pump can be switched to work and the main water pump is controlled to stop working, thereby reducing the failure caused by the abnormal water pump. The main and standby water pumps are connected in parallel when connected.

[0023] In the embodiment, the ship-mounted water pump also includes a domestic water pump. Real-time required flow data is collected by the water demand sensor to the microprocessor, and the output end of the microprocessor is connected to the domestic water pump to adjust the work of the domestic water pump. The water demand sensor can collect water pressure according to the water pressure sensor in the domestic water pipeline, and control the speed of the domestic water pump according to the size of the water pressure to meet the demand of the domestic water pump.

[0024] No matter what kind of ship-mounted water pump is, a noise sensor can be arranged on or around the water pump, the microprocessor is connected to the noise sensor, and the noise sensor is used to collect the noise in the working process of the ship-mounted water pump; the microprocessor controls and alarms the ship-mounted water pump based on the noise data. The noise in the working process of the water pump is certain, and when the noise is abnormal, it can be judged that the water pump works abnormally, so monitoring and alarming are needed. The noise sensor collects the decibel value of the noise in the working process of the water pump to the microprocessor, and the microprocessor judges whether the working noise of the water pump is normal according to the decibel value of the noise. If it is not normal, an alarm can be sent to the remote monitoring platform to realize the monitoring of the noise.

[0025] In a preferred embodiment, the water pump is also connected to be controlled according to the SOC value. For an electric ship, its power is electric energy, and the SOC sensor is used to collect the SOC value of the ship-mounted battery, and the output end is connected to the microprocessor. When the SOC value of the power battery is greater than the set threshold, the microprocessor will not adjust the water pump speed based on the SOC value. When the SOC value is lower than the set threshold, the microprocessor adjusts the water pump speed according to the SOC value, reduces the power consumption of the water pump as much as possible, ensures the power of the ship, and can control the water pump speed to be lower or even stop the water pump work when the SOC is lower, to meet the needs of ship navigation.

[0026] A control rule unit is preset in the remote monitoring platform, which outputs corresponding water pump control instructions to the microprocessor according to the uploaded water pump running parameters. The rule control unit is a rule set by the user according to the actual needs, and the rule in the rule unit can be adjusted to meet the needs of self-adaptive adjustment on the ship.

[0027] The ship of the embodiment comprises the ship-mounted water pump intelligent monitoring system in the above embodiment, and has all the features and technical advantages of the control system.

[0028] The water pump of the embodiment adopts an electronic water pump, and the electronic water pump adopts a high-performance rare earth permanent magnet synchronous motor as a power source, which has the advantages of small size, light weight, high efficiency, high power factor, etc. The rotation speed and torque of the motor are accurately controlled through a PWM controller, so that the water pump can operate at the maximum efficiency under different working conditions, and the energy consumption is effectively reduced. A microprocessor (MCU) or a digital signal processor (DSP) is used as a control center, and the Internet of Things (IoT) technology is combined to realize remote monitoring and local control of the water pump. The flow, lift and power output of the water pump can be automatically adjusted according to actual needs, so that the system can stably operate and the energy efficiency can be maximized. The built-in IoT module can be realized by, for example, a 4G industrial router or a Wi-Fi module, so that the water pump can access the Internet and be connected to a remote monitoring platform. A variety of sensors, such as pressure sensors, temperature sensors and flow sensors, are installed in the water pump, which can monitor various operating parameters of the water pump in real time, such as pressure, temperature, flow, E-flow, voltage, etc. The data collected by the sensors are transmitted to a remote server or a cloud platform in real time through the IoT module, and are stored and managed centrally. At the same time, these data can also be displayed synchronously on terminal devices such as intelligent water conservancy monitoring platforms, computers and mobile phones, so that management personnel can check them at any time.

[0029] Obviously, the specific implementation of the present application is not limited by the above-mentioned manner, and various non-essential improvements made by adopting the method concept and technical scheme of the present application are within the protection scope of the present application.
