Description

Technical Field

[0001] The present application relates to the technical field of analog-to-digital conversion, and in particular to an analog monitor digitization system. Background Art

[0002] Cameras are installed for monitoring in all underground chambers, mining faces, key areas, etc., and they are all network digital cameras, which are easy to install, with clear monitoring images and strong practicality. However, some old cameras are analog cameras, such as the main conveyor belt lane, the upper and lower openings of the auxiliary shaft, and other places where visual monitoring was realized in the early days. In order to meet the requirements of visual monitoring image clarity, it is required to gradually eliminate and update analog cameras, but the supporting monitors are analog monitors and cannot be used with digital cameras. On-site monitoring cannot be realized in the main conveyor belt head, the auxiliary shaft marking room, etc. If digital monitors are installed, it will cost a lot of money, and the replacement cost is high, so the analog cameras are transcoded for use.

[0003] Analog signals can only be processed by software after being converted into digital signals through A / D, and all this is achieved through A / D converters (ADC). Corresponding to analog-to-digital conversion is digital-to-analog conversion, which is the reverse process of analog-to-digital conversion. However, various analog-to-digital conversions on the market still have various problems.

[0004] For example, the analog / digital conversion system disclosed in the authorization announcement number CN101207384B has achieved high-speed sampling rate, low power consumption and low complexity. At the same time, it can also improve the chip yield and effective area utilization rate. This newly proposed analog / digital converter is composed of a flash converter with a high-speed sampling rate and low resolution and a continuous approximate converter with low power consumption and low-speed sampling rate. However, it does not solve the problems that the existing analog-to-digital conversion cannot achieve control and regulation, cannot effectively perform filtering processing before and after conversion, and cannot achieve amplification processing. For this reason, we propose an analog monitor digitization system. Summary of the invention

[0005] In order to make up for the above shortcomings, the present application provides an analog monitor digitization system, aiming to improve the problems that the existing analog-to-digital conversion cannot achieve control and adjustment, cannot effectively perform filtering before and after conversion, and cannot achieve amplification processing.

[0006] The embodiment of the present application provides an analog monitor digitization system, including a control module,

[0010] In the above implementation process, the control module is used to control and adjust the system, and the clock module is used to implement clock delay operation on the system. A data receiving module, a multi-way switch module, a data receiving module, a quantization encoder, a timing pulse generator, a comparison amplifier, a matching filter, a successive approximation register, an analog-to-digital conversion module and a digital filter are provided, which can realize the simultaneous transmission of multiple groups of data information and facilitate control and adjustment. The quantization encoder and the timing pulse generator process the data information and encode and remove redundant data information. The timing pulse generator can effectively realize sequential control, and the comparison amplifier, the matching filter and the successive approximation register can realize the processing, conversion and noise filtering of the data information, maintain the stability of the data information during conversion, and thus improve the efficiency and accuracy of the analog-to-digital conversion.

[0011] In a specific implementation, the data receiving module is electrically connected to an input data interface, the input data interface is used to connect a data information cable, and the data receiving module is used to receive data information transmitted by the input data interface.

[0012] In the above implementation process, data information can be received and connected to complete the transmission and processing of data information.

[0013] In a specific implementation scheme, the multi-way switch module is used to select the data information transmitted by the data receiving module. The multi-way switch module uses a four-to-one or eight-to-one selector as a selection switch, thereby enabling the multi-way switch module to connect several groups of the data receiving modules.

[0014] In the above implementation process, multiple groups of data information are received simultaneously and selectively, which increases the amount of data information received and facilitates the simultaneous operation of multiple groups of surveillance cameras.

[0017] In a specific implementation scheme, the timing pulse generator is used to implement calculations or operations in a specified order, to correctly issue control signals, and the control signals have a certain sequence in time, that is, to output timing pulse signals, thereby realizing coordinated actions. The timing pulse generator uses a trigger to form a timing pulse generator or a shift register to form a timing pulse generator.

[0018] In the above implementation process, effective sequential control of data information transmission is achieved to maintain the operating stability and timing of the system.

The comparison amplifier is electrically connected to a reference voltage, and the reference voltage is used to compare and determine the voltage of the analog signal through the comparison amplifier.

[0020] In the above implementation process, the comparison amplifier can process and compare the data information to prevent the data information from being too weak and being lost.

[0021] In a specific implementation scheme, the matching filter is used to implement filtering processing on the transmitted analog signal, which can effectively filter out the noise in the analog signal and prevent the noise from interfering with the analog signal. The matching filter is a linear filter with the largest ratio of the instantaneous power of the signal at the output end to the average power of the noise.

[0022] In the above implementation process, clutter can be effectively filtered out to maintain the accuracy and effectiveness of the data.

[0023] In a specific implementation, after receiving the start command, the most significant bit of the successive approximation register is set to logic 1, and all other bits are set to logic 0. The output of the successive approximation register is fed back to the analog-to-digital conversion module, and the output of the analog-to-digital conversion module is compared with the input signal. When the output of the analog-to-digital conversion module is greater than the analog input, the most significant bit is reset, otherwise it remains set, and the next most significant bit is set to 1, and the above process is repeated until each bit of the successive approximation register is compared. At the end of this process, the final value of the successive approximation register corresponds to The end of the conversion process is indicated by a ready signal for the analog input value. The analog-to-digital conversion module is used to convert the analog signal into a digital signal. The analog-to-digital conversion module includes a sampling rate and a resolution. The sampling rate is based on the sampling theorem. The sampling frequency fs of the A / D converter should be greater than 2Wa. Due to the influence of factors such as the nonlinearity, quantization noise, distortion and receiver noise of the A / D converter, fs>2.5Wa is generally selected; the selection of the resolution, that is, the number of bits of the sampling value, needs to meet certain dynamic range and digital part processing accuracy requirements. Generally, it cannot be less than 12 bits under the dynamic range requirement of 80dB.

[0024] In the above implementation process, the analog data information can be effectively converted and the conversion rate can be improved.

[0025] In a specific implementation, the digital filter is electrically connected to an output data interface, the output data interface is used to output the converted digital data information, the digital filter is used to effectively filter the converted digital data information, and the digital filter includes a one-dimensional digital filter that processes a signal as a single variable function sequence and a two-dimensional or multi-dimensional digital filter that processes a signal as a two or more variable function sequence.
