Disclosed are a hydraulic system, a control method and a working machine. The hydraulic system includes an oil tank, a working pump, a control cylinder controlling a displacement changing mechanism, a working oil line communicating with an output main path of the working pump, a load-sensing system including a load-sensing circuit outputting hydraulic pressure based on load, a load-sensing valve and a switching-control valve switchable between a first-valve-position and a second-valve-position. When differential pressure between the first and second control ports is greater than a first threshold, the output main path communicates with an input port of the control cylinder; when it is less than the first threshold, the input port communicates with an oil return port of the oil tank. Based on this, operators can switch the hydraulic system between the fixed-displacement mode and the fixed/variable-displacement mode, thereby achieving a better balance between energy conservation and performance.

Embodiments described herein relate to an LDO circuit device and overcurrent protection circuit of an LDO circuit. An overcurrent protection circuit is added to an LDO circuit to process an output current signal of the LDO circuit. When the output current signal of the LDO circuit increases, a voltage of a gate drive signal of a power switch in the LDO circuit is increased through adjustment performed by the overcurrent protection circuit, thereby declining the current capability of the power switch in the LDO circuit and restricting an output current thereof from continuing to increase. After feedback regulation, the output current of the LDO finally reaches to a stable value.

An oscillator comprising an RC oscillator and a bandgap reference source, wherein the bandgap reference source provides a reference current for the RC oscillator, and a temperature coefficient of the reference current is adjustable. Since the oscillation frequency of the RC oscillator has less dependency on a power supply, a clock source having a relatively precise frequency thus can be obtained; and based on the RC oscillator, the bandgap reference source having a temperature compensation function is added, the reference current generated by the bandgap reference source with an adjustable temperature coefficient is used for temperature coefficient compensation to the inherent temperature coefficient of the oscillation frequency of the RC oscillator, thereby reducing the effect of the temperature on the oscillator, so that the output frequency of the oscillator does not change with the temperature as far as possible, which improves the oscillation frequency precision of the oscillator.

The present invention discloses a voltage-controlled oscillator (VCO) circuit, When the VCO circuit works, the DC control voltage is divided into two portions, both of which determine an oscillation frequency of the VCO circuit. One portion of the DC control voltage controls a current provided by the fifth PMOS transistor, and the other portion of the DC control voltage controls the current of the forth PMOS transistor after passing through the third NMOS transistor, thereby controlling oscillation of the VCO circuit. The former plays a leading role when the DC control voltage is relatively low, and the latter plays a leading role when the DC control voltage is relatively high, thereby effectively increasing the use range of the DC control voltage while the high frequency noise interference on the DC control voltage is suppressed. The present invention further discloses a phase-locked loop circuit.

From a plurality of messages provided by at least a first license-exempt access node which give usage information for the at least one channel in license-exempt radio spectrum, there is derived channel-specific statistical traffic information. This information for the channel is then provided to a second access node that controls licensed radio spectrum. Or in another embodiment the second access node can get this information by sensing and measuring the channel itself. The second access node retrieves this information from its local memory and sends on the licensed radio spectrum a downlink message having contents, determined from the channel-specific statistical traffic information, for aiding a user equipment UE to access the channel with a probability defined by the contents. The UE receives this message, extracts the contents, and attempts to access that channel in the license-exempt radio spectrum utilizing the defined probability.
