The invention relates to a crusher, in particular a rock crusher, having a crusher unit (40), to which a band conveyor unit (60) having an endlessly circulating band conveyor is indirectly or directly assigned, wherein a magnetic separator (70) having a magnet (79) is held in the area of the band conveyor unit (60) above the band conveyor in the direction opposite from the direction of gravity, and an adjustment unit (80) is provided, which can be used to change the height of the magnet (79) above the band conveyor. To enable the reliable operation of such a crusher, it is provided according to the invention that the magnetic separator (70) is suspended from at least two limp ties (81, 82, 84, 85), and that the limp ties (81, 82, 84, 85) can be adjusted by means of at least one actuator unit (90) to change the height of the magnet (79).

The invention provides a narrow-linewidth tunable laser system and an operation method thereof. A tunable laser module of the system comprises a semiconductor laser, a driving circuit and a wavelength-tunable control submodule, wherein the driving circuit and the wavelength-tunable control submodule are connected with the semiconductor laser. A switch voltage stabilizer, connected with an inductor and a diode, of a power management submodule enables positive voltage to be converted into negative voltage so as to supply electricity to the system. A microcontroller connected with a host is connected with the driving circuit through digital-to-analog conversion to transmit instructions of the host and states of the laser. The microcontroller and a power failure detection submodule are used for detecting circuit voltage of the laser at regular time, and power is recovered in time when power failure is found out. The operation method of the narrow-linewidth tunable laser system includes the steps that after being initialized, the microcontroller transmits preset default data frames to the laser, the data frames returned by the laser are read, the situation that the data frames have no error is determined, whether power failure occurs or not is detected at regular time, updated instructions of the host are received and transmitted to the laser, and the current working state information of the laser is transmitted to the host. The system only needs to be powered up by a single power supply and can be used easily in an embedded mode. A tuning control interface of the host is simple and visual, and reliable operation is guaranteed through power failure self-detection.

The invention discloses a DC power control method for suppressing multi-infeed DC commutation failure. First, a simplified model of a multi-infeed DC transmission system is established, and then based on a sin-cos component detection and judgment method, the start of DC power control is judged, and then the DC power is determined. The power adjustment amount and the DC power control rate, and finally the DC power control is performed in different commutation failure scenarios according to the DC power adjustment amount and the DC power control rate. The control method of the present invention has fast and accurate control speed, is convenient to realize, has good control effect, does not need wide-area measurement data, has fast control speed, does not interfere with the operation of other equipment, does not require additional investment, and is economical.

The invention discloses a method for modifying the configuration of a cloud host online. The steps include: duplicating the old cloud host twice to obtain two new cloud hosts, respectively the first cloud host and the second cloud host; according to the modified old cloud host Cloud host configuration, configure the corresponding configuration for the first cloud host, and configure the same IP address as the old cloud host for the first cloud host; open the cloud host, prohibit the first cloud host from connecting to the Internet; close the network for the old cloud host, and Activate the network and run the work on the first cloud host; compare the data between the old cloud host and the second cloud host, if the data is the same, no operation is required; if the data is different, copy the different data of the old cloud host to the first cloud host superior. The present invention realizes the modification scheme of the configuration without restarting the cloud host, and enables business systems to seamlessly connect and run uninterruptedly.
