[0021] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
[0022] The words "coupled" or "connected" or "connected" in the specification include both direct connection and indirect connection. Indirect connection is a connection through an intermediate medium, such as a connection through an electrically conductive medium, which may have parasitic inductance or parasitic capacitance; indirect connection may also include connection through other active or passive devices on the basis of achieving the same or similar functional purposes, such as connection through circuits or components such as switches and follower circuits. In addition, in the present utility model, words such as "first" and "second" are mainly used to distinguish one technical feature from another technical feature, and do not necessarily require or imply that there is a certain actual relationship, quantity or order between these technical features.
[0023] like Figure 1 As shown, the power generation system in one embodiment of the utility model includes a control module 10, a conversion module 20, a transformer module 30, a rectifier and filter module 40, a sampling module 51, a temperature sensor 52, a display module 53, an input port 61, an output port 62, a communication interface 63 and a switch S1.
[0024] The input port 61 is used to connect an AC power source. In one embodiment, the AC power source is a 220V standard mains power source. The first end of the switch S1 is connected to the input port 61, and the second end of the switch S1 is connected to the conversion module 20. The switch S1 is used to control the on-off between the conversion module 20 and the AC power source. The conversion module 20 is connected to the transformer module 30. The conversion module 20 is used to convert the AC power source into a DC power source provided to the transformer module 30.
[0025] Specifically, the conversion module 20 includes a connected filter unit 21 and a rectifier unit 22. The filter unit 21 is connected to the second end of the switch S1 to filter the AC power supply and generate a primary AC power. The rectifier unit 22 is connected to the transformer module 30, and the rectifier unit 22 is used to convert the primary AC power into a DC power supply provided to the transformer module 30. The filter unit 21 and the rectifier unit 22 can adopt an existing circuit structure that can achieve their effects.
[0026] The control module 10 is connected to the transformer module 30 to generate a control signal. The transformer module 30 is used to transform the DC power supply based on the control of the control signal and generate an output signal.
[0027] In one embodiment, the voltage transformation module 30 is a program-controlled transformer, whose output range reaches DC0-300V and whose resolution reaches 0.1V, thus meeting the fine power control requirements of the optical fiber demodulation system.
[0028] The rectifier and filter module 40 is connected to the transformer module 30, the output port 62 and the sampling module 51. The rectifier and filter module 40 is used to further rectify and filter the output signal, and transmit the rectified and filtered output signal to the sampling module 51 and the output port 62 to ensure that the final output signal waveform is sufficiently smooth.
[0029] The output port 62 is used to output the output signal. In actual work, the output port 62 can be directly connected to the fiber optic interrogator to provide the direct current required by the fiber optic interrogator to heat the optical cable. The output port 62 can also be connected to a channel expansion module, through which an output signal generated by the power generation system is expanded into output signals of multiple channels to meet the multi-channel power requirements of the fiber optic interrogator.
[0030] The sampling module 51 is connected to the control module 10. The sampling module 51 is used to sample the voltage and current of the output signal and generate a sampling signal, and transmit the sampling signal to the control module 10. The control module 10 is also used to adjust the control signal based on the sampling signal, thereby adjusting the output of the transformer module 30, playing a role of feedback control, and further improving the accurate control of the output signal power. The control module 10 can also set a current protection program and an overvoltage protection program. When the output signal is sampled to be overloaded, short-circuited or other abnormalities, the control module 10 adjusts the control signal and adjusts the transformer module 30 to control the current value and voltage value of the output signal to the current current setting value and voltage setting value, so as to avoid long-term abnormal current or abnormal voltage from damaging the circuit and load.
[0031] The control module 10 is also used to generate a display signal based on the sampling signal. The display module 53 is connected to the control module 10 to display the voltage value and current value of the output signal based on the display signal. The display module 53 is specifically a display screen.
[0032] The temperature sensor 52 is connected to the control module 10. The temperature sensor 52 is used to detect the temperature and generate a temperature signal. The control module 10 is also used to adjust the control signal based on the temperature signal. In actual work, when an abnormal working state generates high temperature, the temperature sensor 52 can promptly feed back the temperature to the control module 10, so that the control module 10 can take corresponding treatment measures according to the actual temperature. For example, if the control module 10 is set with a high temperature protection of 80°C, when the temperature sensor 52 detects that the ambient temperature reaches 80°C, the control module 10 generates a control signal according to the temperature signal to forcibly close the transformer module 30, forcing the system to shut down and cool down to prevent further damage. In addition, a variety of adjustment and control methods can be set as needed to improve the safety and stability of the entire system.
[0033] The communication interface 63 is connected to the control module 10, and the communication interface 63 is used for signal transmission between the control module 10 and external devices. In one embodiment, the communication interface 63 is used to connect to a fiber optic demodulator, which will generate a power demand signal including information such as the required power size and duration according to the working state. After the control module 10 receives the power demand signal through the communication interface 63, it will generate a control signal according to the information contained in the power demand signal to control the transformer module 30 to generate a specified output signal. In other embodiments, the communication interface 63 can also be used to connect other devices that can feedback power demand. In this way, remote and automated power control is achieved, so that the power generation system can be flexibly applied to various engineering scenarios.
[0034] like Figure 2 As shown, an embodiment of the present invention further provides a power generation device, including a power generation system and a housing 70 for installing the power generation system.
[0035] like Figure 2 As shown, the display module 53 and the switch S1 are installed on the front of the housing 70. Figure 3 As shown, an input port 61, an output port 62 and a communication interface 63 are installed on the back of the housing 70. Other components of the power generation system are installed inside the housing.
[0036] like Figure 4 As shown, a heat dissipation assembly 71 is disposed on the surface of the housing 70. In one embodiment, the heat dissipation assembly 71 is disposed on the top surface and the left and right side surfaces of the housing 70. In other embodiments, the heat dissipation assembly 71 may also be disposed on other surfaces of the housing 70 as required.
[0037] Specifically, the heat dissipation assembly 71 includes a plurality of mutually parallel heat dissipation fins. The heat dissipation area is increased by the heat dissipation fins, which has a good heat dissipation effect, so that the device does not need to add a fan, heat dissipation holes and other structures, and the entire machine housing does not need to have holes, thereby improving the dustproof function of the device.
