Abstract: A method for carbon tracking and analysis in a city is provided. Basic information of a target city is acquired. A three-dimensional visual city model is constructed based on the basic information. The target city is divided into a plurality of sub-regions. A carbon emission monitoring plan is formulated based on regional properties of each sub-region. According to the acquired carbon emission monitoring data, a carbon emission change of each sub-region within the current preset period is analyzed by means of linear regression to obtain carbon emission change trend data of each sub-region. Carbon emission tracking is performed based on the carbon emission change trend data. A current carbon tracking route and a carbon prediction route are generated by means of a preset ant colony optimization algorithm. A system non-transitory computer-readable storage medium for implementing carbon tracking and analysis in a city and are also provided.

Abstract: A multi-target dynamic simulation test system for vehicle-mounted millimeter-wave (MMW) radar. The test system includes an antenna turntable, a radar pan-and-tilt head (PTH), a radar echo simulation module, a control module, a signal acquisition module and a display. A test radar is driven by the radar PTH to pan or tilt. The radar PTH and the test radar are both placed in a darkroom module. An antenna is driven by the antenna turntable to pan. The control module sends expected states of the test radar and the antennas to the radar PTH and the antenna turntable, respectively, and sends relative states between host vehicle and virtual targets to the test radar after processing by the radar echo simulation module. The signal acquisition module acquires and stores a detection signal of the test radar, and transmits the detection signal of the test radar to the display for real-time display.

Abstract: “Charging geomagnetic interference resisting method executed by a mobile terminal is provided. The charging geomagnetic interference resisting method includes detecting, by the mobile terminal, a current charging state of the mobile terminal. When the current charging state includes the mobile terminal is being charged, voltage values of multiple preset sampling points are read.

A corresponding magnetic field compensation value is also determined based on the voltage difference value. Then, a current magnetic field value of the mobile terminal is read, and the current magnetic field value and the magnetic field compensation are superimposed to acquire a corresponding actual magnetic field value.
