[0026] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.
[0027] This application discloses an adjustable transmitter circuit. (Refer to...) Figure 1 An adjustable transmitter circuit includes a signal output module 1, a signal processing module 2, and a constant output module 3. The output terminal of the signal output module 1 is connected to the signal processing module 2, and the output terminal of the signal processing module 2 is connected to the constant output module 3.
[0028] Reference Figure 2The signal output module 1 includes a programmable linear Hall chip HR, resistors R1, R2, R3, R4, R5, and R30, capacitors C4 and C5, and a voltage regulator U1. Pin 1 of the programmable linear Hall chip HR is connected to power supply terminal A. Pin 1 of the programmable linear Hall chip HR is also connected to resistor R30. The other end of resistor R30 is connected to pin 1 of the voltage regulator U1. Pin 1 of the voltage regulator U1 is connected to resistor R4. The other end of resistor R4 is connected to pin 2 of the voltage regulator U1. The other end of resistor R4 is also connected to resistor R... 5. The other end of resistor R5 is connected to the ground terminal. Pin 3 of voltage regulator U1 is connected to the ground terminal. Pin 1 of programmable linear Hall chip HR is also connected to capacitor C5. The other end of capacitor C5 is connected to the ground terminal. Pin 2 of programmable linear Hall chip HR is connected to the output terminal of signal output module 1. Pin 2 of programmable linear Hall chip HR is also connected to capacitor C4. The other end of capacitor C4 is connected to the ground terminal. One end of resistor R1 is connected to the power supply terminal +15A. The other end of resistor R1 is connected to pin 1 of voltage regulator U1. Resistors R2 and R3 are both connected in parallel with resistor R1.
[0029] Among them, the voltage regulator U1 can be a voltage reference chip with the model number TL431BCDBZTG4.
[0030] The programmable linear Hall effect (HR) chip can be programmed. Once programmed, the HR chip outputs a control signal based on the detected conditions. Subsequent modules process this control signal to obtain the final desired signal. By modifying the programmed information, the control signal output by the HR chip can be altered, thereby adjusting the final output signal to suit more application scenarios and improving convenience. Compared to related technologies that require the use and preparation of different transmitter models, this reduces operating costs.
[0031] Reference Figure 3 and Figure 4 The signal processing module 2 includes a signal amplification submodule 21 and a filtering submodule 22. The input terminal of the signal amplification submodule 21 is connected to the output terminal of the signal output module 1, that is, the input terminal of the signal amplification submodule 21 is connected to pin 2 of the programmable linear Hall chip HR. The output terminal of the signal amplification submodule 21 is connected to the filtering submodule 22, and the output terminal of the filtering submodule 22 is connected to the constant output module 3.
[0032] Reference Figure 5 and Figure 6The constant output module 3 includes a first-stage constant output submodule 31 and a second-stage constant output submodule 32. The input terminal of the first-stage constant output submodule is connected to the output terminal of the signal processing module 2, that is, the input terminal of the first-stage constant output submodule is connected to the output terminal of the filtering submodule 22. The second-stage constant output submodule 32 is connected to the first-stage constant output submodule 31.
[0033] The components of the first-stage constant output submodule 31 are as follows: Figure 5 As shown. The first-stage constant output submodule 31 uses a sliding rheostat GIN, resistor R20 and resistor R21 to form a voltage divider circuit, so that the non-inverting input terminal of the operational amplifier N2B receives a voltage, and then outputs to control transistor BG1 to obtain the final desired value, and performs negative feedback to ensure that the desired signal output by the first-stage constant output submodule 31 is a constant signal.
[0034] The components of the second-stage constant output submodule 32 are as follows: Figure 6 As shown. The second-stage constant output submodule 32 can also output the required value, and the output at the second-stage constant output submodule 32 has greater driving capability.
[0035] Furthermore, by adjusting the resistors in the first-stage constant output submodule 31 and the second-stage constant output submodule 32, a constant voltage signal or a constant current signal can be obtained. Specifically, when resistors R24 and R25 in the first-stage constant output submodule 31 are soldered, while resistors R26, R27, R28, and R29 in the second-stage constant output submodule 32 are not soldered, the output is a constant voltage signal; when resistors R24 and R25 in the first-stage constant output submodule 31 are not soldered, while resistors R26, R27, R28, and R29 in the second-stage constant output submodule 32 are soldered, the output is a constant current signal. In other words, by adjusting the resistors, the desired signal—whether a constant current signal or a constant voltage signal—can be adjusted. This allows for different application scenarios, improving applicability.
[0036] The implementation principle of an adjustable transmitter circuit in this application embodiment is as follows: the signal output module 1 outputs a control signal based on the detection status, which is then processed by the signal processing module 2. The constant output module 3 outputs a constant required signal based on the processed control signal, thus completing the detection feedback process and outputting a constant required signal, which makes the adjustment more stable. Furthermore, by using a programmable linear Hall chip HR, different control signals can be output when the detection status is the same by changing the programmed code, thereby achieving adjustability to meet the needs of different application scenarios.
[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
