4results about How to "Avoid signal delay" patented technology

The application provides a collision detection circuit, a method and a vehicle, and belongs to the technical field of vehicle detection, wherein the collision detection circuit comprises a data acquisition module and at least two monitoring modules connected with the data acquisition module respectively, and the data acquisition module is connected with a controller of the vehicle; when the collision signals of the at least two monitoring modules are synchronously acquired, the data acquisition module transmits the collision signals to the controller, so that the controller controls to close high-voltage components of the vehicle. The collision detection circuit of the vehicle provided by the application can avoid the operation and processing steps of the controller on the collision signals, and can instantly determine the existence of a collision event through the collision signals of the two monitoring modules. The controller controls to close the high-voltage components of the vehicle according to the collision signals, so that the detection failure or signal delay is prevented, the response time of the system power-off during the collision is shortened, and the safety and reliability of the system are improved.

The application provides a charging pile gun lock control circuit and method, and relates to the technical field of new energy vehicle charging, in particular to a gun lock control circuit of a charging pile. The application aims to solve the problems of a large number of components, a large volume, high cost, slow response speed and lack of power-off emergency processing mechanism of the existing gun lock control circuit due to the use of discrete components. The core scheme includes a gun lock identification module U1, which receives a processed external control signal SS-A, SS-B and outputs a driving signal; a switch control circuit, which controls the potential of the first input pin INA1 of U1 according to the SS-A signal level; and an emergency processing circuit, which utilizes the energy storage of the energy storage element EC1 when the system loses power, and uses the one-way conduction element D1 to pull down the potential of the second input pin INB of U1, so as to automatically trigger the output of U1 to drive the relay L1 to act, and retract the lock tongue. The circuit structure is simple, and safe and reliable gun lock control can be realized only by hardware.
