Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please refer to Figures 1-6 One embodiment of this utility model provides a water conservancy alarm device, including a sensor component 1 and a control component 2;

[0035] The sensor assembly 1 is installed at the observation point via a mounting bracket. The sensor assembly 1 includes a water affairs simulation sensor 11 and a water affairs digital sensor 12.

[0036] The control component 2 includes a housing and a control board 4. The control board 4 has an MCU circuit module 41, a water affairs simulation sensor acquisition circuit 42, a water affairs digital sensor acquisition circuit 43, and an alarm circuit 44. The water affairs simulation sensor acquisition circuit 42 is connected to the water affairs simulation sensor 11 through an interface, and the water affairs digital sensor acquisition circuit 43 is connected to the water affairs digital sensor 12 through an interface.

[0037] The MCU circuit module 41 has an analog input interface (AIN_PWR_CTL), a digital input interface (DIN_PWR_CTL), and an alarm signal output interface (DO_PWR_CTL). The analog input interface (AIN_PWR_CTL) is connected to the water affairs analog sensor acquisition circuit 42, the digital input interface (DIN_PWR_CTL) is connected to the water affairs digital sensor acquisition circuit 43, and the alarm signal output interface (DO_PWR_CTL) is connected to the alarm circuit 44. The MCU circuit module 41 is used to output an alarm command when abnormal sensor data is detected. The alarm circuit 44 is configured to start when the MCU circuit module outputs an alarm command, connect to the alarm in the management center, and issue a continuous alarm prompt.

[0038] The water alarm device in this embodiment can achieve the following technical effects:

[0039] 1. The MCU circuit module 41 of this utility model can be connected to the water analog sensor 11 and the water digital sensor 12 simultaneously through the water analog sensor acquisition circuit 42 and the water digital sensor acquisition circuit 43. This allows the MCU circuit module 41 to output an alarm command when it detects abnormal sensor data. The alarm circuit 44 is powered on and connected to the alarm in the management center to issue a continuous alarm prompt, realizing alarms for various abnormal situations. At the same time, the combination of the water analog sensor 11 and the water digital sensor 12 can achieve a more accurate water level alarm effect and water quality alarm, avoid false alarms and improve versatility.

[0040] In one application scenario of this embodiment, the MCU circuit module 41 also has an analog input output voltage control interface (AIN_VOUT_CTL). The output voltage control interface (AIN_VOUT_CTL), analog input interface (AIN_PWR_CTL), and digital input interface (DIN_PWR_CTL) are used to realize the reception of sensing data from the water analog sensor 11 and the water digital sensor 12.

[0041] Please refer to Figure 3 In one embodiment of this utility model, the water simulation sensor acquisition circuit 42 includes a plurality of signal waveform calibration chips U19; the signal waveform calibration chip U19 is connected in series with a single corresponding water simulation sensor 11.

[0042] The main function of a signal waveform calibration chip is to calibrate the analog signals acquired by the sensor to ensure the accuracy and consistency of the signals. At the same time, by calibrating the signal waveform, the error of the sensor output can be reduced and the measurement accuracy can be improved.

[0043] In this embodiment, by connecting the signal waveform calibration chip U19 in series with the corresponding water simulation sensor 11, it is ensured that the signal of each sensor can be individually calibrated and conditioned. This allows for optimization for different types of sensors to meet their respective measurement requirements. Therefore, this embodiment can improve the accuracy of the signals acquired by the water simulation sensor 11 by the water simulation sensor acquisition circuit 42.

[0044] Please refer to Figure 3 In one embodiment of the present invention, the water simulation sensor acquisition circuit 42 further includes a signal format conversion chip U20, and a plurality of signal waveform calibration chips U19 are connected in parallel to the signal format conversion chip U20.

[0045] The signal format conversion chip is responsible for converting the calibrated analog signal into a digital signal or other standard format suitable for subsequent processing. This conversion allows the signal to be further processed and analyzed by the MCU or other digital systems.

[0046] In this embodiment, multiple signal waveform calibration chips U19 are connected in parallel to signal format conversion chip U20, which can simultaneously calibrate multiple sensor signals, effectively improving the performance of the water affairs simulation sensor acquisition circuit 42 when acquiring multiple or more water affairs simulation sensors 11.

[0047] Please refer to Figure 4 In one embodiment of the present invention, the water digital sensor acquisition circuit 43 further includes an anti-phase buffer circuit U25, which is disposed at the output terminal of the water digital sensor acquisition circuit 43.

[0048] The main function of the inverting buffer circuit is to invert the input digital signal, that is, to change logic 0 to logic 1 and logic 1 to logic 0, so as to match the output signal of the sensor with the logic level standard of the system.

[0049] In this embodiment, by placing the inverting buffer circuit U25 at the output terminal of the water digital sensor acquisition circuit 43, the accurate acquisition and reliable transmission of sensor signals can be ensured.

[0050] In one embodiment of this utility model, the water simulation sensor 11 includes one or more of a water level sensor, a water pressure sensor, and a water temperature sensor;

[0051] The water digital sensor 12 includes one or more of the following: pH sensor, turbidity sensor, dissolved oxygen sensor, and wind speed sensor.

[0052] Please refer to Figure 6In one embodiment of the present invention, the water alarm device further includes a communication module 5, which is disposed on the side of the housing and is electrically connected to the alarm circuit 44.

[0053] The communication module 5 is any one of a WiFi module, a 4G module, a 5G module, a satellite communication module 5, an Ethernet port, or a LoRa module.

[0054] In this embodiment, by setting up communication module 5, the alarm device can communicate with the management center to facilitate data transmission and remote monitoring.

[0055] In one embodiment of the present invention, the water alarm device further includes a memory 6, which is connected to the MCU circuit module 41.

[0056] In this implementation, by setting up memory 6, water data can be stored locally, avoiding data loss due to communication interruptions or other reasons.

[0057] In one embodiment of the present invention, a display screen 3 is further included, which is embedded in the front of the housing, and the MCU circuit module 41 is connected to the display screen 3.

[0058] In this embodiment, the display screen allows on-duty personnel to visually view the current water data when they inspect the water alarm device.

[0059] In one embodiment of this utility model, the alarm is at least one of a warning light and a buzzer alarm.

[0060] In this embodiment, by setting up warning lights and buzzer alarms, the on-duty personnel can be promptly and effectively alerted to the occurrence of a situation requiring early warning and handling. This facilitates the on-duty personnel to arrive at the warning location in a timely manner to resolve the warning information, or to carry out corresponding contingency plans based on the alarm information.

[0061] Please refer to Figure 5 In one embodiment of this utility model, the alarm circuit 44 is provided with at least two inputs, DO1 and DO2, and the alarm circuit 44 is provided with signal isolation optocoupler OPT3 and signal isolation optocoupler OPT4 respectively.

[0062] There is no electrical connection or common ground between the input and output circuits of the signal isolation optocoupler. Therefore, various interference signals on one side of the circuit are difficult to feed to the other side through the signal isolation optocoupler, avoiding the generation of interference signals from common impedance coupling and preventing interference and noise transmission between circuits.

[0063] In this embodiment, by setting a signal isolation optocoupler in the alarm circuit, even if the water affairs analog sensor acquisition circuit 42 or the water affairs digital sensor acquisition circuit 43 experiences a short circuit or other fault, or even if the input signal line is short-circuited, the equipment connected to the output interface of the alarm circuit will not be damaged, because the input and output circuits of the optocoupler can withstand several thousand volts of high voltage. The water affairs alarm device in this embodiment can not only achieve effective isolation of multiple alarm signals, but also enhance the security of the equipment connected to the water affairs alarm device.

[0064] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
