Problems solved by technology

[0003] However, in the current bayonet system and the application of the strobe light, there is no good information exchange between the bayonet system and the strobe light. The bayonet system can only issue a trigger command to the strobe light to trigger the strobe light to flash. , but other communication processes cannot be carried out, and the flashing light cannot feed back its own information to the bayonet
In addition, to communicate according to the current communication protocol, it is necessary to add hardware devices such as specific communication signal lines between the bayonet system and the flashing light, which increases the complexity and cost of the hardware, and cannot realize all bayonet systems and flashing lights. The transmission line settings between flashes are unified

Abstract

The embodiment of the invention discloses a transmission signal processing method, device and system and a storage medium. The method is executed by a controller and comprises the steps of: determining a sender of a target data signal transmitted by a camera or a flashing light, wherein the target data signal is a digital coded signal; determining a receiving state or a decoding state of the target data signal according to the sender of the target data signal; and processing the target data signal based on the receiving state or the decoding state of the target data signal. According to the invention, the receiving state or the decoding state of the target data signal is determined by judging the sender of the target data signal, so that the target data signal is processed in a targeted manner according to different senders, and the transmitted target data signal is selectively received or analyzed; and therefore, two-way communication between the camera and the flashing light is realized under the condition that a signal transmission line does not need to be added.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of bayonet monitoring, and in particular to a transmission signal processing method, device, system and storage medium. Background technique [0002] The road vehicle intelligent detection and recording system (referred to as the bayonet) can realize the automatic collection and processing of road vehicle information, which involves the detection of the target object by the smart camera and the supplementary light process. During this process, the smart camera detects the situation of passing vehicles, and sends a trigger pulse (usually a switch value or a level value) to the flashing light through the trigger signal line, thereby triggering the flashing light to flash and realize ambient supplementary light. [0003] However, in the current bayonet system and the application of the strobe light, there is no good information exchange between the bayonet system and the strobe light, and...
