Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a transmission signal processing method according to a first embodiment of the present invention. The transmission signal processing method provided by the embodiment can be applied to the situation of processing the signals transmitted in two directions between the camera and the flashing light. The method may be specifically executed by a signal processing device, the device may be implemented by software and/or hardware, the device may be integrated in a controller, the controller may be connected to a camera and/or a flash lamp, the camera may be a camera or a video camera, referring to fig. 1, and the method of the embodiment of the present invention specifically includes:
s110, determining a sender of a target data signal transmitted by a camera or a flashing light, wherein the target data signal is a digital coding signal.
The target data signal is sent from the camera to the flash lamp or sent from the flash lamp to the camera, optionally, if the target data signal is sent from the camera to the flash lamp, the target data signal is used for controlling or configuring the flash lamp, and if the target data signal is sent from the flash lamp to the camera, the target data signal is used for feeding back a control instruction or a configuration instruction sent by the camera, so that the camera knows the state parameter information of the flash lamp at present. The target data signal may be transmitted through at least one signal line of any type, for example, as shown in fig. 2, a camera receiving end and a flash lamp output end are added in a current bayonet system, and the target data signal may be transmitted through a signal line connecting the camera and the flash lamp in the current bayonet system without adding an additional signal line, thereby reducing hardware cost and complexity.
Alternatively, the transmission timing of the target data signal may be set by a technician according to actual conditions. For example, the camera may actively send the target data signal to the flash lamp, or the flash lamp may actively send the target data signal to the camera, or the camera may first send the target data signal to the flash lamp to control or configure the flash lamp, and then the flash lamp sends the target data signal to the camera to feed back the control instruction or the configuration instruction of the camera.
Optionally, the target data signal is a digital coded signal, where the digital coded signal includes at least one bit of data bit, and may include, for example, a flag bit, a data bit, and a parity bit, and may also be provided with other coded bits, which is not specifically limited in the embodiment of the present invention. The start bit is used to verify the target data signal to prevent the target data signal from being transmitted incorrectly, for example, the start bit may be set to 4 bits, the standard data bit may be set to 0101, and if the start bit of the received target data signal matches the standard data bit, the start bit may be verified to pass. The parity bit is used to verify whether the number of "1" s in the target data signal is odd or even. For example, when the number of the digital signals "1" in the check bits and the data bits is odd, the parity bit should be "0", and when the number of the digital signals "1" in the check bits and the data bits is even, the parity bit should be "1", so as to ensure that the number of the data signals "1" in the digital coding is odd. Similarly, when the number of the digital signals "1" in the check bits and the data bits is odd, the parity bits should be "1", and when the number of the digital signals "1" in the check bits and the data bits is even, the parity bits should be "0", so as to ensure that the number of the data signals "1" in the digital code is even. The data bits are used for analyzing and obtaining the response instruction information or the feedback information. In the embodiment of the present invention, the number of bits of the target data signal is not limited, and may be set by a technician according to an actual situation.
Optionally, the coding length of the target data signal is determined according to the effective trigger time interval of the flashing light. Specifically, if the target data signal is a signal sent to the flash lamp by the camera, the camera sends a trigger pulse to trigger the flash lamp to flash to realize light supplement before sending the target data signal to the flash lamp, and due to the application condition of the flash lamp, the two flash flashes cannot be continuous, that is, the time interval for receiving the trigger pulse needs to be greater than the effective trigger time interval of the flash lamp to meet the power return requirement of the energy storage capacitor of the flash lamp, so that the sum of the transmission time of the target data signal sent to the flash lamp by the camera and the analysis time of the flash lamp on the target data signal, or the sum of the transmission time of the target data signal sent to the flash lamp by the camera and the analysis time of the flash lamp on the target data signal and the transmission time of the flash lamp feeding the target data signal back to the camera are less than the effective trigger time interval to ensure the complete transmission of the target data signal, and normal transmission of trigger pulses.
Specifically, the controller determines the sender of the target data signal transmitted by the camera or the strobe light so as to realize different processing of the target data signal in a targeted manner.
And S120, determining the receiving state or the decoding state of the target data signal according to the sender of the target data signal.
Wherein the sender comprises a camera or a flashing light. The receiving state includes a normal receiving state or a rejecting state. The decoding state includes a normal decoding state or a non-decoding state.
Specifically, in order to realize the signal transmission in the half-duplex form between the camera and the strobe, the sender of the received target data signal needs to be determined, so as to perform different forms of targeted processing on the target data signal according to different senders. In addition, as shown in fig. 3, since the signal transmission lines are connected, when the output end 4 in the camera sends out the target data signal, the receiving end 1 in the flash lamp and the receiving end 3 in the camera both receive the target data signal, and at this time, the receiving end 4 in the camera is not required to process the target data signal, and similarly, when the output end 2 in the flash lamp sends out the target data signal, the receiving end 1 in the flash lamp and the receiving end 3 in the camera both receive the target data signal, and at this time, the receiving end 3 in the flash lamp is not required to process the target data signal. In the embodiment of the invention, the sender of the target data signal is judged firstly, and then the receiving state or the decoding state of the target data signal is determined according to the sender of the target data signal.
Optionally, the determining, by the controller located in the camera, a receiving status or a decoding status of the target data signal according to the sender of the target data signal includes: if the sender of the target data signal is a flashing light, the decoding state is a normal decoding state or the receiving state is a normal receiving state; and if the sender of the target data signal is a camera, the decoding state is a non-decoding state or the receiving state is a rejecting state.
Optionally, if the controller is located in the flashing light, determining a receiving state or a decoding state of the target signal according to the sender of the target data signal includes: if the sender of the target data is a camera, the decoding state is a normal decoding state or the receiving state is a normal receiving state; and if the sender of the target data is the flashing light, the decoding state is the non-decoding state or the receiving state is the rejecting state.
Specifically, if the controller in the camera determines that the sender is a flashing light according to the target data signal, the controller should normally receive the target data signal or normally decode the target data signal, so that the decoding state is set to a normal decoding state, or the receiving state is set to a normal receiving state; if the sender is judged to be the camera according to the target data signal, the target data signal should be refused to be received or not processed, and the decoding operation is not carried out, so that the decoding state is set to be a non-decoding state or the receiving state is set to be a refusing state. For the controller in the flashing light, if the sender is judged to be the camera according to the target data signal, the target data signal is normally received or normally decoded, so that the decoding state is set to be the normal decoding state, or the receiving state is set to be the normal receiving state; if the sender is judged to be the flashing light according to the target data signal, the target data signal is refused to be received or not processed, and the decoding operation is not carried out, so that the decoding state is set to be a non-decoding state or the receiving state is set to be a refusing state.
It should be noted that the above-mentioned scheme in the embodiment of the present invention is also applicable to the case when the controller is connected to the camera and the flashing light at the same time, and the method for determining the recipient of the target data signal and the method for processing the target signal are the same as those described above, and are described in detail in the above-mentioned scheme.
And S130, processing the target data signal based on the receiving state or the decoding state of the target data signal.
Specifically, the controller may determine whether to receive or decode the target data signal according to a reception state or a decoding state of the target data signal. Wherein the receiving of the target data signal may be performed in accordance with an input of the control I/O. And if the decoding state is a normal decoding state, performing decoding operation on the target data signal according to a decoding rule, and if the decoding state is a non-decoding state, not decoding the target data signal. And if the receiving state is a normal receiving state, controlling the I/O port to normally receive the target data signal and normally perform subsequent operation on the target data signal, and if the receiving state is a rejection state, controlling the I/O port not to receive the target data signal.
According to the technical scheme of the embodiment of the invention, a sender of a target data signal transmitted by a camera or a flashing light is determined; determining a receiving state or a decoding state of the target data signal according to a 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.

And S250, determining that the sender of the target data signal is a camera, and the decoding state is a non-decoding state or the receiving state is a rejection state.

Example four
In the fourth embodiment of the present invention, a detailed description is given of a specific flow of signal processing in the case of processing a signal transmitted in two directions between a camera and a flash lamp, details which are not described in detail in the fourth embodiment are described in the above embodiments, and a technical solution in the fourth embodiment of the present invention is executed by a controller connected to the camera and/or the flash lamp.
(1) The camera sends a trigger pulse and a target data signal.
In the bayonet system, when a camera detects that a vehicle passes through, a trigger pulse is sent to a flashing light through a trigger output end in the camera to trigger the flashing light to flash to realize light supplement, and a target data signal is sent out through a trigger pulse index. And after the trigger output end in the camera finishes sending the target data signal, controlling a receiving end in the camera to be in a state of receiving the target data signal and in a state of decoding the target data signal. In the embodiment of the present invention, the effective triggering time interval of the flashing light is set to be 60ms, the target data signal is a 12-bit encoded signal, which includes 4 as a start bit, 7 as a data bit, and 1 as a parity bit, as shown in fig. 6, 7-bit data can represent 128 instructions. In the case where the 1-bit encoding has a transmission time of 2ms, the transmission time of the target data signal is 24 ms. The target data signal fed back by the flashing light is 12, the transmission time is 24ms, so the transmission time of the target data signal is 48ms, the analysis time of the target data signal is less than 12ms, and the total time required for processing the target data signal is less than 60 ms.
(2) The strobe light receives the trigger pulse and the target data signal and decodes the target data signal.
And after the flashing lamp receives the trigger pulse, flashing is carried out, a target data signal is received, and the target data signal is decoded by the controller. Before decoding, checking the start bit in the target data signal; if the check of the initial bit in the target data signal passes, checking the parity check bit in the target data signal; if the parity check bits in the target data signal pass the check, the data bits in the target data signal are decoded. If the check on the start bit and the parity bit is not passed, the decoding procedure is exited. And the flashing light determines target instruction information corresponding to the data bit in the target digital signal according to the mapping relation between the data bit code in the digital code and the camera instruction information. For example, if the data bit in the received target data signal is "0000001", the target command information corresponding to the data bit may be determined as "flash set to low brightness level" according to table 1 in the above embodiment.
(3) And the flashing light generates a feedback target data signal and sends the feedback target data signal to the camera.
The flash lamp generates target feedback information according to the target instruction information, determines a data bit code corresponding to the target feedback information according to a mapping relation between the data bit code in the digital code and the flash lamp feedback information, further generates a feedback target data signal by the start bit, the data bit and the parity bit, and sends the target data signal to the camera. And in the process of sending the target data signal to the camera by the output end in the flashing light, controlling the receiving end in the flashing light to reject the target data signal or not decoding the target data signal after receiving the target data signal. And after the target data signal is sent, controlling a receiving end in the flashing light to be in a state of receiving the target data signal and in a state of decoding the target data signal.
(4) And the camera receives the target data signal fed back by the flashing light and decodes the target data signal.
After the camera receives the target data signal fed back by the flashing light through the receiving end of the camera, the fed back target feedback information corresponding to the fed back target data signal is determined according to the mapping relation between the data bit in the digital coding signal in the signal decoding rule of the flashing light and the flashing light feedback information, and therefore the current state of the flashing light is obtained. For example, if the data bit in the target data signal of the feedback received by the camera is "0000001", it can be determined from table 2 that the target feedback information corresponding to the data bit is "low brightness level setting success".
According to the technical scheme of the embodiment of the invention, the camera sends the trigger pulse and the target data signal to the flash explosion lamp, so that the control and the configuration of the flash explosion lamp of the camera are realized, the target data signal fed back is generated by the flash explosion lamp according to the instruction signal obtained by decoding, and the target data signal is fed back to the camera, so that the bidirectional signal transmission between the camera and the flash explosion lamp is realized under the condition of only one signal wire without adding an additional signal transmission wire, the information transmission form and the information transmission content are enriched, and the state of the flash explosion lamp can be more comprehensively known by the camera.
