The invention discloses an optimizing method of a self-correcting frequency synthesizer capable of optimizing properties of a voltage-controlled oscillator. The method comprises the following steps that: when a chip is electrified or a channel is changed each time, a frequency self-correcting loop in a synthesizer self-correcting circuit is started firstly, and a frequency sub-wave band code necessary for the voltage-controlled oscillator is searched; secondly a current self-correcting loop in the synthesizer self-correcting circuit is started, and a current sub-wave band code that an output amplitude of the voltage-controlled oscillator achieves an appointed amplitude is searched, so that the voltage-controlled oscillator works in a minimum power consumption, a good phase noise property is obtained, and at the same time the properties of the voltage-controlled oscillator are not changed when process deviation and temperature change occur; after the accomplishment of frequency correction and current correction is judged by a state machine, a synthesizer enters into the frequency self-locking process of a phase-locked loop; and the optimization and correction process is ended. The invention further discloses the self-correcting frequency synthesizer capable of optimizing the properties of the voltage-controlled oscillator. A wider frequency adjustment range can be obtained, and good local oscillator spectrum purity is obtained through small power consumption; and the optimizing method is suitable for the self-correcting frequency synthesizer of a transceiver with low power consumption, multiple modes and multi-band frequency.

By adopting the pushing of the supercharging cylinder, a plurality of kilograms of the air pressure can be converted into the highest 10MPa of the pressure, and at the same time, the automatic compensation function of the pressure loss can be realized. The small-sized pressurizing device is advantageous in that the carrying is convenient, the structure is simple, the maintenance is convenient, the use is practical and reliable; the water in the water tank can be recycled, and the use is environmental friendly and energy-saving.
