Intellectualized mobile telephone signal shielding device of automobile operator cabin

Abstract

The invention asks for an intelligent mobile phone signal shielding device for protecting a vehicle cab, relating to the technical field of electron. When the vehicle runs, a sensor detects a speed signal, and an intelligent control circuit switches the speed signal and outputs a control signal. A control signal shielding device opens to shield the mobile phone signal. When the vehicle stops, the speed signal detected by the sensor is zero and the control mobile phone signal shielding device closes automatically, thus realizing the intelligent control of the mobile phone signal shielding device. The invention carries out automatic detecting on the vehicle running state based on the existing technical principle of shielding device and automatically opens or closes the signal shielding device according to the detecting result to realize the intelligent shielding of the mobile phone signal when the vehicle runs, thus being able to effectively stop a driver to dial or answer the mobile phone when driving the vehicle and ensuring the safe driving of the vehicle. The invention is especially suitable to be popularized and used on bus.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a mobile terminal signal shielding device. Background technique [0002] When the mobile phone works, within a certain frequency range, the mobile phone and the base station communicate with each other through radio waves, and complete the transmission of data and sound with a certain baud rate and modulation method. Generally, the mobile phone signal jammer generates scanning signals in a fixed frequency band through a scanner, and forms garbled code interference in the received signal of the mobile phone, so that the mobile phone cannot detect the normal data sent from the base station, thereby realizing signal shielding (interference). At present, various mobile phone signal jammers (devices) are mainly used in gas stations, conference rooms and other specific places where the use of mobile phones is prohibited and where safety and quietness are required. The radius is ge...

AI Technical Summary

Problems solved by technology

At present, various mobile phone signal jammers (devices) are mainly used in gas stations, conference rooms and other specific places where the use of mobile phones is prohibited and where safety and quietness are required. The radius is generally above 5M, and the startup and shutdown must be done manually, without intelligent functions

Therefore, even if the existing universal mobile phone signal jammer is installed in the vehicle cab, it is still impossible to effectively control the driver's dialing and answering the mobile phone when driving the vehicle due to the need for manual activation and shutdown.
