Description

Technical fields:

[0001] This utility model relates to a device for acquiring and detecting the operating parameters of a synchronous motor in a pumping station. Background technology:

[0002] A pumping station is a water-lifting facility that converts electrical energy into water energy for irrigation or drainage. It consists of structures such as pumps, synchronous motors, electrical equipment, pipelines, and pump houses. Its core functions include liquid transportation and pressure regulation. It is equipped with a remote monitoring system to monitor parameters such as water level and flow rate and to intelligently schedule pumps.

[0003] In pumping station systems, synchronous motors are essential functional components. As the power source of the pumping station system, their operating performance directly affects the overall efficiency and accuracy of the pumping station. Therefore, it is necessary to detect and provide feedback on the operating parameters of the synchronous motor. Most existing data acquisition and detection devices use a single type of sensor to collect and detect different operating parameters of the synchronous motor multiple times. The overall process takes a lot of time, resulting in an excessively long data acquisition and detection cycle, which affects the normal operation of the pumping station system.

[0025] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0026] like Figure 1-7 As shown, the pump station synchronous motor operating parameter acquisition and detection device includes a housing, and inside the housing 1 are:

[0027] The controller includes a data acquisition component, a timer, a display screen, and an audible and visual alarm.

[0031] The controller is an STM32F103C8T6 with 64 pins. The controller is connected to the AD converter via pin 15, to the audible and visual alarm via pins 33 and 34, and to the timer via pin 45.

[0032] The AD converter is model AD8551 and has 8 pins. The AD converter is connected to pin 15 of the controller through pin 6, and the AD converter is connected to the infrared sensor, ultrasonic sensor and photoelectric sensor through pin 3.

[0035] Heat dissipation holes are provided at the bottom of the insulating protective layer.

[0036] The working principle of the pump station synchronous motor operation parameter acquisition and detection device in this embodiment of the utility model is as follows: Based on the integrated control function of the controller, and in conjunction with multiple types of electrical components and functional components, it can acquire multiple categories of synchronous motor operation parameters at the same time node, reduce the acquisition and detection cycle, simplify the workflow, replace the existing single acquisition method, and fuse and calculate the multi-category synchronous motor operation parameters to accurately obtain the actual operating status of the synchronous motor. Once an abnormal situation occurs, it can be repaired in time, thereby ensuring the long-term stable operation of the pump station system.

[0037] Due to the special nature of synchronous motor operation in pumping station systems, it is necessary to collect and detect the real-time operating parameters of synchronous motors to ensure the normal and stable operation of the pumping station system. Most existing data collection and detection methods are single-detection methods, which have low overall efficiency and cannot detect and provide feedback in a timely manner when abnormal conditions occur.

[0038] The overall solution mainly includes a housing 1, within which is a controller. Electrically connected to the controller are a data acquisition component, a timer, a display screen, and an audible and visual alarm. The data acquisition component includes an AD converter, to which are electrically connected a photoelectric sensor, an infrared sensor, and an ultrasonic sensor. The photoelectric sensor detects the real-time rotational speed of the synchronous motor shaft using photoelectric feedback. The infrared sensor detects the real-time temperature of the synchronous motor using infrared sensing, thereby obtaining the real-time power of the synchronous motor. The ultrasonic sensor detects the real-time operating pressure of the synchronous motor using ultrasonic detection. The timer transmits clock pulse signals to the controller to ensure real-time acquisition and detection of the synchronous motor's operating parameters. The display screen displays the acquired synchronous motor operating parameters in real time. The audible and visual alarm emits an audible and visual alarm signal when abnormal conditions occur.

[0039] In actual use, the insulating protective layer 3 is fixed to the housing 1 by bolts and slots to form an integrated acquisition and detection device. The acquisition component is placed close to the synchronous motor. The acquisition component includes an acquisition base. Multiple detection windows corresponding to sensors are provided on the acquisition base 2. Through the multiple detection windows set in different positions, the photoelectric sensor, infrared sensor and ultrasonic sensor can give full play to their functions and accurately detect the speed parameters, temperature parameters and pressure parameters of the synchronous motor to obtain the operating status of the synchronous motor.

[0040] Generally, the detection threshold for each operating parameter is preset in the controller. When the collected speed, temperature and pressure parameters exceed the detection threshold, the audible and visual alarm will be activated to alert the user and prompt the user to perform timely maintenance on the synchronous motor.

[0041] The housing of this application is a structure that is spliced ​​and fixed to the insulating protective layer, which facilitates assembly and is a technical feature that distinguishes it from existing devices.

A red indicator light is connected to the first electromagnetic relay, and a speaker is connected to the second electromagnetic relay. The first electromagnetic relay is connected to pin 34 of the controller, and the second electromagnetic relay is connected to pin 33 of the controller, which can trigger the audible and visual alarm signal in a timely manner.

[0045] Preferably, the timer is a DS1302 with 8 pins. A fourth capacitor and a fourth resistor are provided between pins 6 and 7 of the timer. Pin 7 of the timer is connected to pin 45 of the controller, which can continuously transmit clock signals to the controller to realize real-time detection and control of the controller.

[0046] A heat dissipation hole is provided at the bottom of the insulating protective layer, which can reduce the operating temperature rise of the controller and ensure the stable operation of the controller.

[0047] It should be noted that the acquisition component is generally located on the top of the housing, which makes it convenient to approach the synchronous motor for testing during actual operation.

[0048] In summary, the pump station synchronous motor operation parameter acquisition and detection device in this embodiment of the present invention, based on the integrated control function of the controller and in conjunction with multiple types of electrical components and functional components, can acquire multiple categories of synchronous motor operation parameters at the same time point, reduce the acquisition and detection cycle, simplify the workflow, replace the existing single acquisition method, and fuse and calculate multiple categories of synchronous motor operation parameters to accurately obtain the actual operating status of the synchronous motor.
