Disclosed are a collision detection method, a magnetic radio frequency device and a communication system. A first magnetic radio frequency device performs magnetic communication access with a second magnetic radio frequency device using a magnetic channel; and the first magnetic radio frequency device further emits a collision detection request signal via the magnetic channel and judges whether there are a plurality of second magnetic radio frequency devices colliding with each other according to whether a response signal of the collision detection request signal is received or according to the received response signal. During the whole process of collision detection, the interaction between relevant instructions is performed via the magnetic channel without the participation of a radio frequency module and independent of a radio frequency channel, so the radio frequency interaction time will not be affected, improving the communication efficiency of the first magnetic radio frequency device and the second magnetic radio frequency device to a certain extent; furthermore, the situation where relevant instructions for detecting collisions on the radio frequency channel interfere with the application data can be avoided, thus the accuracy of collision detection results and the reliability of radio frequency communication can be improved.

The invention discloses a random switching device for automobile body forming clamps. The random switching device comprises a clamp switching support provided with a clamp switching mechanism. The clamp switching support is composed of multiple supporting legs and a support platform fixed to the tops of the supporting legs. The clamp switching mechanism comprises lower-layer switching mechanism assemblies arranged on the left side and the right side of the clamp switching support and fixed to the ground and upper-layer switching mechanism assemblies arranged on the left side and the right side of the support platform. The random switching device is divided into an upper layer and a lower layer and composed of X-direction conveying segmental rails, lifters, Y-direction horizontally-moving mechanisms and clamp storehouses, the occupied area is small, mixed line production of at least four automobile models can be achieved, and the more efficient clamp switching capacity is achieved through the small occupied area, the simple structural manner and the scientific switching principle.

The bicycle pedal of which the magnetism is controlled by the brake comprises a bicycle, electromagnetic induction coils, an accumulator and a controller. The bicycle comprises a bicycle frame, the pedals, a handlebar and the brake; the electromagnetic induction coils are arranged in the pedals; the accumulator is arranged on the bicycle frame and used for connecting the electromagnetic induction coils with the controller; the controller comprises a control module, a detection module, a gear module, a display module and a control button; the control button is used for controlling the status switching of the accumulator; the control module is connected with the detection module, the gear module, the display module and the control button; the control button comprises a main switch and a sub switch; the main switch is arranged on the handlebar; the sub switch is controlled by the brake. The electromagnetic induction coils and the brake are used in a matched way, thus the problem that the pedals and the shoe soles slide relative to each other is solved, and meanwhile the time at which the feet of a rider leave the pedals in case of emergency is not influenced.

The application provides a watch. The watch includes a casing, and the casing includes a body and side walls bent and connected from the periphery of the body. The transparent substrate is arranged on the side wall. The transparent display screen, at least part of the transparent display screen is set on the transparent substrate. In the watch provided by this application, a transparent display screen is added, and at least part of the transparent display screen is provided on a transparent substrate. First of all, when the transparent display is not working or displaying, it has a transparent effect and will not affect the time when the user watches the watch from the transparent substrate. When the transparent display is working, it will display patterns in the corresponding area of ​​the transparent substrate, such as weather, steps, messages, news, etc. can be displayed. Or at night, use the transparent display screen to display the specific time, thereby increasing the functionality of the watch and improving the texture of the watch.

The invention provides a control device and method for vehicle headlamp cleaning and belongs to the technical field of vehicle headlamp cleaning, wherein the control device and method can be used for solving the problems of single working mode and inconvenient control in the vehicle headlamp cleaning. The control device comprises a washing motor, a headlamp cleaning mechanism, a vehicle speed sensor, a switch information acquirer and a controller; the washing motor, the vehicle speed sensor and the switch information acquirer are all connected with the controller, the vehicle speed sensor canacquire a vehicle speed signal and send the vehicle speed signal to the controller, the switch information acquirer can acquire the switch signals of an ignition switch, a headlamp switch, a headlampcleaning switch and a front air window washing switch and send the switch signal to the controller; and the controller analyzes and judges the received vehicle speed signal and switch signal and sends a control signal to control the work of the washing motor or not according to the judgment result. The control method comprises: judging before headlamp cleaning; controlling the headlamp cleaning by the headlamp cleaning switch; and controlling the headlamp cleaning by the front air window washing switch. The system is accurate in control, convenient and high in security.

The method includes following steps. (1) Determining central coordinate of each subzone in activation set. (2) Making out straight lines perpendicular to connecting lines between center of reference subzone and each center of adjacent subzones as well as passing through center of reference subzone, and areas enclosed by said straight lines and borderline of the reference subzone are selected as direction areas, if the said enclosed areas are near to adjacent subzones. (3) Based on positioning method, positioning result of UE in reference subzone is obtained. (4) Superposed areas between direction areas obtained from step (2) and positioning result obtained from step (3) are as final positioning result for UE. Comparing with prior art, the invention raises precision of positioning UE, simple without complex calculation, and not affecting time for obtaining result by using RNC.

The invention provides a test method of an SGPIO (Serial General Purpose Input / Output) signal on an SAS (Serial Attached Small Computer System Interface) backboard. The method comprises the following steps of: accessing an MINI SAS cable in the SAS backboard and a test system; and then carrying out controlling test through a visualized unit. The SAS backboard structurally comprises a data generating and processing unit simulating an SGPIO signal, the visualized unit and an MINI SAS interface. Compared with the prior art, the test method of the SGPIO signal on the SAS backboard has the advantages of reasonable design, simple structure, convenient use, easy maintenance, and the like, greatly simplifies the test flow under the conditions that server and hard disk resources are not occupied, avoids repeatedly plugging a hard disk and repeatedly booting up or shutting down a server in a traditional test mode and realizes the graphic interface of the SGPIO signal test flow.
