There are many kinds of guidance systems, which are generally divided into 6 categories according to guidance methods. ① Autonomous: This guidance system controls the flight of the aircraft according to the internal or external reference benchmark of the aircraft, it does not need any human control and navigation, nor does it need ground equipment to work with, so the anti-interference ability is strong. The systems that use this method are inertial guidance systems inertial guidance systems, astronomical guidance systems.
Guidance comes by signalThe basic types of source are: wired guidance, radio guidance, radar guidance, infrared guidance, laser guidance, acoustic guidance, geomagnetic guidance, inertial guidance and astronomical guidance. Wired guidance is a way of remote control guidance, the guidance station constantly tracks the target, forms guidance instructions, and transmits the instructions to the guided weapon through the wired form to control the flight trajectory, so that it hits the target.
The basic types of guidance according to the signal source are: wired guidance, radio guidance, radar guidance, infrared guidance, laser guidance, acoustic guidance, geomagnetic guidance, inertial guidance and astronomical guidance. Wired guidance system mainIt is composed of guidance and control device, optical sight, operating handle and control wire.
The missile guidance system is mainly divided into four types: autonomous, homing, remote guidance and compound guidance. The autonomous guidance system is an independent mode of operation, without specific information or external equipment, the missile can navigate to the target. Such systems are widely used in missiles that attack fixed targets on the ground, such as the U.S. Hercules and Minuteman intercontinental ballistic missiles, and rely primarily on inertial guidance.. There are many kinds of guidance systems, which are generally divided into six categories according to the guidance method: autonomous, beam, and fingerReam, search, image matching and compound. 2 The autonomous guidance system controls the flight of the aircraft according to the internal or external reference benchmark of the aircraft, without any human control and navigation, and without the cooperation of ground equipment.
Command guidance system can be divided into radar tracking and optical tracking according to the way the target tracks and corrects the missile's flight path. The radar tracking command guidance system processes the observation data (the distance and Angle between the missile and the target) through a computer, calculates the flight error, and then transmits the information to the missile via radio waves. After the missile receives the command, the control system (Similar to autopilot) drives the actuator (rudder or engine) to correct.
1, QI wireless charging is required to do the RED directive, the EU CE certification has a special test standard for wireless charging equipment, the test standard is EN 303 417 V1. Deep light standard.
2, in order to successfully pass the RED certification, the manufacturer needs to provide a series of detailsAll documents, these are important evidence of product compliance: User Manual Circuit schematic Circuit block diagram and Operation description Circuit wiring diagram and component list Antenna Specifications and Charger LVD report Fixed frequency software (BT and WiFi products must be provided) RED certification is not only a threshold for products to enter the European market, but also a key step for manufacturers to demonstrate the quality and compliance of their products.
3, wireless products CE-RED certification is a necessary condition to enter the European market, for manufacturers, to obtain CE-RED certification can improve the market competitiveness of products, and reduce trade risks. By understanding andCompliance with the relevant directive requirements and procedures can ensure the safety and environmental protection of wireless products, and thus smooth entry into the European market.
4. The RED directive applies only to wireless products. Removed the requirement for communication products. Radio broadcast receivers are included in the scope required by the RED directive.
1, open the phone, and then click the dial button on the desktop of the phone. 2, the pop-up interface, click the button in the lower left corner. 3, the pop-up interface, click the bottom left corner of the dialnumber 4, enter the dial, enter *#*#2846579#*#* *. 5, after the input is completed, it will enter the engineering mode.
2. You can enter the engineering mode of a Huawei mobile phone in either of the following ways: Dialing. First, find and click the "Dial" icon on the home screen of your Huawei phone, and then enter the specific code "*#*#2846579#*#*" in the dial screen. After the input is completed, press the dial button, and the phone will automatically jump to the engineering mode interface.
3. There are two methods for Huawei mobile phones to enter the engineering mode. First and foremost
