Description

Technical Field

[0001] This invention belongs to the field of power technology for broadcast transmitters, specifically an automated conversion system for shortening the power conversion time of medium wave broadcast transmitters. Background Technology

[0002] Medium wave broadcasting, as a traditional form of broadcasting, has a long history and a broad audience base worldwide. As a crucial facility for program transmission and emergency broadcasting, the hardware of transmitters has developed rapidly in recent years. However, this does not necessarily mean a significant improvement in broadcast safety. Power is the fundamental guarantee for medium wave transmitter transmission, requiring a dual-circuit power supply system with both mains and dedicated power, as well as automatic transfer switches to ensure the smooth operation of UPS equipment and diesel generators, and timely power supply in the event of a power outage. Current technology requires an automatic transfer switch to send a signal, and the power receiver can only start the backup engine after receiving the signal, taking 3-6 seconds for the transfer to occur. This results in a 4-8 second interruption in medium wave transmitter transmission before recovery. Although UPS equipment can convert stored electrical energy into AC power through an inverter to power the load, achieving the goal of zero-interruption output voltage switching, this consumes power from the UPS battery. If the diesel generator cannot start and supply power in time, the large power consumption will shorten the battery life. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide an automated conversion system that can start the diesel generator to supply power in a timely manner, has low power consumption of the battery in the UPS equipment, has a simple structure, and is convenient and practical to shorten the power conversion time of the medium wave broadcast transmitter.

[0005] The objective of this invention and the solution to its main technical problem are achieved by the following technical solutions: The present invention discloses an automated switching system for shortening the power conversion time of a medium-wave broadcast transmitter, comprising a solenoid valve, mains power, a generator, a battery, and a push switch. The solenoid valve is hinged to the push switch and the generator via a connecting rod. The solenoid valve is connected to the mains power and a power acquisition device via wires. The power acquisition device is connected to the generator via wires. The generator is connected to the push switch via wires. The push switch is connected to a time-delay relay via wires. The time-delay relay is connected to the battery via wires.

[0006] There are several power acquisition devices.

[0007] The power acquisition device is connected to the conversion server via wires, the conversion server is connected to the switch via wires, and the switch is connected to the client and the data server via wires respectively.

[0008] The push switch is a contact-type push switch.

[0009] Compared with existing technologies, this invention has significant advantages. As can be seen from the above technical solution: a solenoid valve is hinged to a hand-operated switch and a generator via a connecting rod. The solenoid valve is connected to the mains power and a power acquisition unit via wires. The power acquisition unit is connected to the generator via wires. The generator is connected to the hand-operated switch via wires. The hand-operated switch is connected to a time-delay relay via wires. The time-delay relay is connected to the battery via wires. The solenoid valve and the push-button of the hand-operated contact switch are hinged via a connecting rod. In the event of a power outage, the valve core of the solenoid valve retracts, causing the connecting rod to move. The connecting rod causes the hand-operated switch to close instantly, connecting the battery to the generator starter via wires. This direct linkage instantly connects the battery and starter, enabling the diesel generator to start generating electricity. This allows for timely switching of power supply equipment, preventing excessive power consumption by the medium-wave transmitter and preventing excessive consumption of the energy stored in the UPS equipment that could lead to interruption of the medium-wave transmitter transmission. This achieves timely start-up of the diesel generator to supply power, low power consumption of the battery in the UPS equipment, and a simple, convenient, and practical structure.

[0013] The following detailed description, in conjunction with the accompanying drawings and preferred embodiments, provides a detailed account of the specific implementation methods, structures, features, and effects of the present invention.

[0014] This invention discloses an automated conversion system for shortening the power conversion time of a medium-wave broadcast transmitter, comprising a solenoid valve 1, mains power 2, generator 3, battery 4, manual push switch 5, conversion server 6, switch 7, client 8, data server 9, power acquisition unit 10, and time-delay relay 11. The solenoid valve 1 is hinged to the manual push switch 5 and generator 3 via connecting rods. The solenoid valve 1 is connected to the mains power 2 and power acquisition unit 10 via wires. The power acquisition unit 10 is connected to the generator 3 via wires. The generator 3 is connected to the manual push switch 5 via wires. The manual push switch 5 is connected to the time-delay relay 11 via wires. The time-delay relay 11 is connected to the battery 4 via wires. There are multiple power acquisition units 10. The power acquisition units 10 are connected to the conversion server 6 via wires. The conversion server 6 is connected to the switch 7 via wires. The switch 7 is connected to the client 8 and data server 9 via wires. The manual push switch 5 is a contact-type manual push switch.

[0015] In operation, mains power 2 connects to solenoid valve 1. The valve core of solenoid valve 1 generates an electromagnetic field that is drawn into the valve. When mains power 2 is interrupted, the electromagnetic field of solenoid valve 1 disappears, and the spring inside solenoid valve 1 pushes the valve core out of the valve. The valve core then drives the connecting rods to move. One connecting rod causes the hand-operated switch 5 to close instantaneously, connecting battery 4 to the starter motor of generator 3 via a wire. The starter motor of generator 3 then disconnects the power supply to battery 4 via time delay relay 11, and the starter motor of generator 3 stops rotating. Simultaneously, the other connecting rod drives the throttle of generator 3 to accelerate. This direct linkage instantly connects the battery and starter motor, enabling the diesel generator to start generating electricity and promptly switch power supply equipment. This prevents the medium-wave transmitter from consuming too much power and prevents the UPS equipment from excessively consuming its stored energy, which could lead to an interruption in the medium-wave transmitter's transmission. When mains power 2 is restored, the valve core of solenoid valve 1 generates an electromagnetic field that is drawn into the valve. The valve core then drives the connecting rods to move. One connecting rod causes the hand-operated switch 5 to open instantaneously, disengaging the hand-operated switch 5. Simultaneously, the other connecting rod causes the throttle of generator 3 to close, and the engine stops generating electricity.

[0016] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
