The material metering device provided by the invention is used for improving the metering accuracy of the admixture metering container.

The invention discloses a method and system for detecting the corona state of a corona discharge ion source. The method includes: acquiring discharge sound data when the ion source is discharging; In comparison, judge the corona state of the corona discharge ion source. The method for detecting the corona state of the corona discharge ion source provided by the embodiment of the present invention obtains the discharge sound data when the ion source is discharged through the sound collection device, and compares the discharge sound data with the sound data in the audio library through the audio recognition algorithm , so as to judge the corona state of the corona discharge ion source. Therefore, adopting this detection method does not need to actually measure the high voltage at the ion source, and does not need to use the existing current measuring device, the design cost is low, the detection method is simple, and it solves the problem of the discharge phenomenon of the ion source detected by the current measuring device in the prior art. Technical problems with fragile devices.

The embodiment of the invention discloses a control method and device for a gate of a card reader, financial equipment and a storage medium. The method comprises the steps that after it is detected that a card is inserted into an recognizer, a digital identification code on the card is obtained; according to a category code contained in the digital identification code, it is found whether or not acorresponding bank identification code is stored; and when the corresponding bank identification code is found, the gate of the card reader is opened. The control method and device for the gate of the card reader, the financial equipment and the storage medium have the advantages that the technical scheme solves the problem that the card reader of the financial equipment is damaged easily due tothat a bank card user accidentally or a lawless person deliberately inserts a card medium not belonging to bank cards into the financial equipment, and the maintenance cost of the financial equipmentis reduced at the same time.

The invention discloses a core neutron flux measuring device and a measuring circuit protection method. The device comprises: a self-powered detector and a secondary meter measuring circuit, wherein the self-powered detector and the secondary meter A discharge device is connected between the measuring circuits, realizing the release of the electric energy generated by the self-powered detector, protecting the measuring circuit of the secondary instrument, and making the core neutron flux measuring device not easy to be damaged.

The invention discloses a method and a device for charging detection on USB type C equipment. The method comprises steps that a voltage of a configuration signal of the USB type C equipment is acquired; whether the voltage of the configuration signal surpasses a first threshold is detected; if the voltage of the configuration signal is detected to surpass the first threshold, high voltage charging for the USB type C equipment is forbidden; if the voltage of the configuration signal is detected to be lower than the first threshold, high voltage charging for the USB type C equipment is permitted. The method is advantaged in that a technical problem that the configuration signal can be easily damaged during high voltage charging for the USB type C equipment in the prior art is solved.
