The invention discloses a magnetic suspension rotor harmonic current inhibition method based on parallel FORC and phase lag-lead compensation, and the method comprises the steps: firstly building a magnetic suspension rotor dynamical model comprising quality imbalance and sensor harmonic; secondly employing a magnetic suspension rotor harmonic current inhibition method based on a parallel FORC structure. The structure enables internal models of a harmonic at all frequencies to be converted into a plurality of parallel units with the similar structures, and quickly improves the dynamic performances of a system. The method also employs the phase lag-lead compensation to improve the stability and dynamic performances of the system. The invention proposes a method for quickly and adaptively adjusting the controller gain for a specific harmonic signal. The method achieves the dynamic optimization of the dynamic performances and stability. The method achieves the inhibition of a harmonic component of a current of a magnetic bearing coil in a magnetic suspension rotor, and is suitable for the harmonic current inhibition of the magnetic suspension rotor system with the quality imbalance and sensor harmonic.

The invention relates to a multifunctional tourist attraction service system with a team organization function and a realization method. Based on a communication function, a GPS (Global Position System) positioning function, a network connection function, a voice input and playing function, an information display and operation function and the like on an intelligent mobile terminal, the intelligent mobile terminal is connected with a network server and a processor to form the multifunctional tourist attraction service system with the team organization function; the service system is used for carrying out real-time dynamic monitoring on users and providing a series of service supports including supports on positioning and navigation of the users, tourist attraction information display and broadcasting and salvation services, so that a leader or a tour guide can conveniently manage and lead, and furthermore, the management efficiency and the communication efficiency are improved; and the service system has abundant tourism functions, can provide functions and services of accurate navigation, introduction, route recommending, reminding of lagging behind, warning of dangerous zones, tourist attraction congestion reminding and the like, and can bring relatively great convenience for the users in tourist attractions.

The invention discloses a sagger automatic continuous charging device for an electronic kiln, and belongs to the technical field of electronic kiln auxiliary facilities. The sagger automatic continuous charging device comprises a rack, a spiral material conveying tube, a material storage box and a power transmission mechanism. The rack is supported on a terrace. The spiral material conveying tube is fixed on the top of the rack, a screw rod shaft is matched in a tube cavity of the spiral material conveying tube, and a spiral sheet is formed on the screw rod shaft. A closed end is formed at the left end of the spiral material conveying tube, and an opened end is formed at the right end of the spiral material conveying tube. The material storage box is fixedly connected with the top of the rack, and the bottom of a material storage box cavity is communicated with the tube cavity of the spiral material conveying tube. The power transmission mechanism is connected with the screw rod shaft. The sagger automatic continuous charging device for the electronic kiln is characterized in that the opened end of the spiral material conveying tube is connected with a bend connector in a matched mode, the bend connector is communicated with the tube cavity, a bend connector discharging opening of the bend connector faces downwards, the left end of the screw rod shaft stretches out of the tube cavity to form a screw rod shaft extension shaft section, the screw rod shaft extension shaft section is supported on the top of the rack, and the power transmission mechanism is connected with the screw rod shaft extension shaft section. Discharging smoothness is guaranteed, the spiral sheet can be prevented from scraping the inner wall of the tube cavity, and accordingly materials can be accurately led into a sagger.

The invention relates to the field of liquid crystal display technologies, in particular to a liquid crystal display panel which comprises a driving switch array substrate, a color optical filter substrate, a liquid crystal layer and frame adhesive. The driving switch array substrate comprises a display area and a non-display area, and the non-display area is arranged on the periphery of the display area and is further provided with a first spacing portion for spacing the frame adhesive; the color optical filter substrate is opposite to the driving switch array substrate; the liquid crystal layer is arranged between the driving switch array substrate and the color optical filter substrate and is positioned in the display area; the frame adhesive encircles the liquid crystal layer and is arranged between the driving switch array substrate and the color optical filter substrate; the frame adhesive is positioned in the non-display area and is arranged on the first spacing portion. The liquid crystal display panel has the advantages that frame adhesive spacing components are arranged on the first substrate, and accordingly the frame adhesive coating accuracy can be improved.
