[0030] The following will clearly and completely describe the concept and technical effects of the utility model in conjunction with the embodiments, so as to fully understand the purpose, features and effects of the utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the utility model without creative effort are all within the protection scope of the utility model.

[0031] In the description of the embodiments of this utility model, the term "several" means one or more, and the term "multiple" means two or more. The terms "greater than," "less than," and "exceeding" should be understood as excluding the stated number, while the terms "above," "below," and "within" should be understood as including the stated number. The terms "first" and "second" should be understood as distinguishing technical features and not as indicating or implying relative importance, the number of indicated technical features, or the order of the indicated technical features.

[0032] Reference Figure 1 and Figure 2This utility model provides a detection probe, which includes a housing and a detection circuit. The housing includes a housing cavity 110 and a detection prism 120. The detection circuit includes a transmitter 210 and a receiver 220, both of which are disposed within the housing cavity 110. In this embodiment, the detection prism 120 is fixedly connected to one end of the housing cavity 110. The transmitter 210 is used to send a detection signal to the detection prism 120. When the detection prism 120 is in a preset state, it feeds back the detection signal to the receiver 220. In a specific embodiment, when the detection probe proposed in this embodiment is used to detect whether it has left the target water body (or other solution), the transmitting end 210 is excited by the external control device to emit a detection light signal to the detection prism 120. If the detection prism 120 is in the target water body, the detection light signal will be refracted at the detection prism 120. At this time, the receiving end 220 cannot receive the detection light signal, and therefore cannot provide feedback to the external control device, indicating that the detection probe is in the target water body. However, when the detection probe leaves the target water body and is exposed to air, the detection light signal emitted by the transmitting end 210 is reflected by the detection prism 120 to the receiving end 220, and then the feedback signal is received by the external control device connected to the receiving end 220, indicating that the detection probe is now outside the target water body and exposed to air. In this embodiment, to ensure the reliability and stability of the detection circuit, the detection circuit includes a photoelectric sensor circuit. The transmitting end of the detection circuit includes a light-emitting diode, and the receiving end includes a photosensitive device. The direction of the detection light signal (i.e., the detection signal) emitted by the light-emitting diode D1 is consistent with the orientation of the receiving surface of the photosensitive device k. In this system, the detection light signal emitted by LED D1 is transmitted to the detection prism 120. When the detection prism 120 is in the target water body, the detection light signal emitted by LED D1 is refracted at the detection prism 120, and the photosensitive device k cannot receive the detection light signal. When the detection prism leaves the target water body and is in the air, the detection light signal emitted by LED D1 is reflected by the detection prism 120, and the photosensitive device k receives the detection light signal and sends an electrical signal back to the external control device, triggering an external alarm. This solves the technical problem in related technologies where it is impossible to effectively monitor whether various instruments are immersed in water and function properly during aquaculture, providing an accurate and reliable detection probe.

[0033] Reference Figure 1 and Figure 2In some embodiments, to achieve accuracy in the refraction and reflection of the detection light signal by the detection prism 120, the detection prism 120 includes a first detection edge 121 and a second detection edge 122. The first detection edge 121 and the second detection edge 122 form a 90-degree angle, so that when the first detection edge 121 and the second detection edge 122 are outside the target water body (i.e., in a preset state), the detection light signal emitted by the light-emitting diode D1 to the first detection edge 121 is reflected to the second detection edge 122, and the second detection edge 122 reflects the detection light signal to the photosensitive device k, and then feeds back an electrical signal to the external control device to indicate that the detection probe is outside the target water body.

[0034] Specifically, in some embodiments, the detection prism 120 (i.e., including the first detection edge 121 and the second detection edge 122) is made of glass, styrene, vinyl chloride, PC, or ABS. The detection prism 120 made of any of the above materials can meet the requirements for its function.

[0035] Reference Figure 3 In some embodiments, if aquaculture is carried out in the target water body, the water temperature often needs to be strictly controlled to provide an ideal scientific aquaculture environment. Therefore, in this embodiment, the detection probe also includes a temperature acquisition circuit TH1, which is disposed in the housing cavity 110. The temperature acquisition circuit TH1 collects the current temperature information and transmits it to the external control device, thereby enabling real-time monitoring of the current temperature information of the target water body.

[0036] Specifically, in some embodiments, the temperature acquisition circuit TH1 is implemented through a temperature sensor, which is set in the cavity of the housing to realize real-time monitoring of the current temperature information of the target water body.

[0037] Reference Figure 4This utility model embodiment also provides a detection and control system, which includes a main control unit, a heating unit, and a detection probe as described in any of the above embodiments. In this embodiment, the main control unit is electrically connected to the heating unit and the detection probe, respectively. The main control unit controls the transmitting end in the detection probe to continuously emit a detection light signal to the detection prism. Typically, the detection probe is fixedly placed in the target water body. At this time, the detection light signal cannot be reflected to the receiving end in the detection probe, and therefore the main control unit cannot receive the control signal fed back by the detection probe. At this time, the temperature sensor set in the detection probe will transmit the current temperature information of the target water body to the main control unit. The system controls the heating unit to operate based on the received current temperature information, preventing the temperature in the target water from falling below or exceeding a preset temperature range. When the detection probe is outside the target water and exposed to air, the detection light signal is reflected at the detection prism and received by the receiver. The receiver then sends a control signal back to the main control unit, which in turn controls the heating unit to stop heating. This prevents the main control unit from accurately controlling the heating unit's operation if the current temperature information transmitted from the temperature sensor in the detection probe is not the actual temperature of the target water, thus avoiding the target water temperature falling outside the preset temperature range. This invention provides a detection and control system that achieves accurate and reliable heating control by incorporating a detection probe. When applied to ornamental or farmed fish, placing the detection probe and heating unit in the target water accurately and effectively controls the target water within a preset temperature range and enables real-time monitoring of the target water temperature.

[0038] Reference Figure 5 In some embodiments, to ensure the stable and reliable operation of the heating unit, the heating unit includes a heating element, a heating switch control circuit, and a heating power supply circuit. The control terminal of the heating switch control circuit is connected to the main control unit, and the two output terminals of the heating power supply circuit are respectively connected to the two ends of the heating element. The heating switch control circuit includes a switching element. When the switching element is closed under the control of the control unit, the switch control circuit is activated, forming a circuit in the heating power supply circuit to provide power to the heating element. When the switching element is open under the control of the control unit, the switch control circuit is de-circuited, breaking the circuit in the heating power supply circuit and preventing it from providing power to the heating element. This achieves precise control of the heating element's operating state, i.e., precise control of the temperature of the target water body where the heating element is located.

[0039] In some embodiments, to achieve stable and reliable control of the heating power supply circuit, the heating switch control circuit includes a first switching transistor and a first relay; wherein, the control terminal of the first switching transistor is connected to the main control unit, and the output terminal of the first switching transistor is connected to the control terminal of the first relay. In this embodiment, when the heating device needs to work to heat the target water, the main control unit outputs a control signal to turn on the first switching transistor, thereby causing the first relay to close. At this time, the heating power supply circuit and the heating device form a closed loop, providing working power to the heating device, and the heating device is in working state to heat the target water. When the heating device does not need to work, the main control unit outputs a control signal to turn off the first switching transistor, thereby causing the first relay to open. At this time, the heating power supply circuit and the heating device loop are disconnected, and the heating device stops working.

[0040] Reference Figure 6 In some embodiments, when the detection and control system proposed in this utility model is applied, it further includes a display unit to allow users to intuitively obtain the current operating status of the detection and control system. The display unit is connected to the main control unit and is used to display preset data information sent by the main control unit. Typically, the preset data information includes the current temperature information collected by the detection probe. In other embodiments, the detection and control system also includes a temperature adjustment control button, which is connected to the main control unit. The temperature adjustment control button is used to receive external temperature control signals and transmit them to the main control unit. The main control unit controls the working status of the heating unit according to the received external temperature control signals. That is, after the user obtains the current temperature information of the target water body through the display unit, they can send an external temperature control signal to the main control unit as needed through the temperature adjustment control button, thereby achieving temperature adjustment of the target water body.

[0041] Reference Figure 3 , Figure 7 , Figure 8 , Figure 9 and Figure 10 The following specific embodiment illustrates the implementation of some important components of the detection and control system provided by this utility model. It should be noted that this embodiment is merely a specific example; no creative improvements are made on this embodiment, and various simple variations still fall within the protection scope of the detection system proposed by this utility model. In this embodiment, reference is made to... Figure 7 The main control unit is implemented using a CA51F351P6 MCU; refer to Figure 3 The detection probe utilizes a photoelectric sensor, and a temperature sensor TH1 is incorporated within the probe to collect current temperature information; (Refer to...) Figure 8The first switching transistor includes a first transistor Q1, the first relay includes a relay JQ1, and the heating element includes an resistor R11; the heating power supply circuit includes a 78L05 voltage regulator chip, a non-isolated buck switching power supply constant voltage control driver chip LP-2179A, and its peripheral circuitry; refer to... Figure 9 The display unit includes a digital tube display. In this embodiment, the detection probe sends a signal to the main control unit indicating whether it is in the target water body, as well as the current temperature information collected by the temperature sensor TH1. When the detection probe is still in the target water body, the main control unit cannot receive the electrical signal fed back by the photoelectric sensor in the detection probe. At this time, the temperature sensor TH1 sends the collected current temperature information to the main control unit. When it is necessary to heat the target water body, the main control unit controls the first transistor Q1 to conduct and the relay JQ1 to close. At this time, the 8L05 voltage regulator chip is used to regulate the external input power supply and output it to the LP-2179A. The LP-2179A is used to provide working power to the heating device R11. When the main control unit receives the electrical signal fed back by the photoelectric sensor in the detection probe or the current temperature information collected by the temperature sensor TH1 is lower than the preset temperature range, the main control unit outputs a control signal to turn off the first transistor Q1 and disconnect the relay JQ1, thereby disconnecting the heating power supply circuit that provides working power to the heating device R11, and the heating device R11 stops working. (Refer to...) Figure 10 Furthermore, during the operation of the detection and control system provided in this embodiment of the present invention, the display unit is used to display the current temperature information collected in real time by the temperature sensor TH1 in the detection probe, so that the user can intuitively obtain the current working status of the detection and control system and accurately adjust the working status of the detection and control system according to the displayed current temperature information.
