The invention discloses a non-oxidation non-reduction fire refined copper process. The oxygen concentration in copper liquid at the converting endpoint ranges from 0.05 to 0.3 percent; the oxidation-reduction operation in an anode furnace is canceled; gas which does not react with copper is blown into the anode furnace and the copper liquid is mixed forcibly until refining operation endpoint is reached, and oxygen and impurities which are contained in the copper liquid originally react with the gas so as to remove the impurities and oxygen at the same time. The non-oxidation non-reduction fire refined copper process has simple technology, convenient operation, high productivity effect, and low energy consumption without a reducer, avoids black smoke pollution, and is suitable for the large-scale industrial production.

The invention discloses a remote control system of a walking excavator, and belongs to the technical field of walking excavators. The remote control system is characterized in that an electronic controlled switching valve is serially connected into an original pilot control oil circuit and is used for opening or closing the hydraulic pilot oil circuit, then a proportional electromagnetic valve is connected between a hydraulic pilot control handle and pedal combination and a main control multi-way valve in parallel, relays (1) are respectively connected onto a circuit of a starting relay, a circuit of a flameout electromagnetic valve, a circuit of a loudspeaker and a circuit of a brake electromagnetic valve in parallel, and a remote control module is added to the remote control system and comprises a PLC (programmable logic controller), a transmitter and a receiver. An electronic control unit is introduced into the remote control system on the premise that merits of automatic operation and full-hydraulic pilot control flexible operation are kept, modification of a remote control function is facilitated, and the remote control system is simple in structure and low in cost. Besides, a group of relays (1) is connected onto the starting circuit, the flameout circuit, the loudspeaker circuit and the brake circuit in parallel respectively and are used for actuating remote control instructions to control basic electric functions, and the remote control functional module mainly comprises the transmitter, the receiver, the PLC and an accelerator actuator.

The invention relates to an iterative autonomous navigation and positioning method based on polarization pose information coupling. First, the polarization sensor measures the polarization angle and calculates the sun vector of the computer system, and converts it into the sun vector in the geographic coordinate system; then, from the geographic coordinate system The sun vector calculates the sun altitude and azimuth at this moment; calculates the sun's declination through time, and calculates the longitude and latitude of the moving body; uses the position and time to update the sun vector of the navigation system, and uses the new measurement information to update the sun vector under the machine system With the gravity vector, the three-dimensional attitude of the moving body is solved through the attitude transformation direction cosine matrix, and the two-step loop iteration of position update and attitude update is used to realize the concurrent calculation of the pose with polarization as the only external information source. This method uses polarization as the only external information source, and realizes the simultaneous calculation of position and attitude. It is applicable to the navigation of moving objects under satellite rejection and magnetic interference conditions, and the required sensors are low in cost, small in size, and easy to implement.
