Detailed Description
As shown in fig. 1, the power transmission line visual monitoring system based on 5G wireless communication of the present invention includes a sensing module 1, a network module 2, a management platform 3, and an application module 4.
The sensing module 1 is electrically connected with the network module 2 and is used for carrying out panoramic on-line real-time monitoring on a line, carrying out intelligent identification on image information, converting the acquired image information into digital information and outputting the digital information to the network module 2; the intelligent recognition function of the perception module 1 is rough, and only some obvious hidden danger information can be recognized. The sensing module 1 comprises an image acquisition unit, and the image acquisition unit acquires images through an image acquisition device; the image processing unit is used for preprocessing the image and converting the image information of the image acquisition unit into a digital signal; the storage unit is used for temporarily storing the image acquired by the image acquisition unit and other data information. After the storage unit temporarily stores the data information generated by the image acquisition unit and the image processing unit, the data entering the sending queue can be quickly sent out. The image processing unit pre-processing the image includes: detecting image background and image noise reduction, deleting useless background information, and setting wavelet coefficients smaller than a threshold value to zero through wavelet shrinkage to leave actual signals. Thus, by setting a suitable threshold, coefficients smaller than the threshold are first zeroed out, while wavelet coefficients larger than the closed value are retained; then obtaining an estimation coefficient through threshold function mapping; finally, inverse transformation is carried out on the estimation coefficient, so that denoising and reconstruction can be realized; background pictures of images, such as invalid information of sky, ground, vegetation and the like, are complex, so that the images are too large and are also large even after being compressed; after the image background is deleted, the useful information expression of the image is not influenced, the size of the image can be reduced, and the transmission efficiency is improved.
Before the sensing module 1 outputs the digital information to the network module 2, the digital information is encrypted: and the image processing unit codes the two continuous images acquired by the image acquisition unit and then stores the codes of the two images in a staggered manner to generate an encrypted image code. The image information acquired by the sensing module can generate a sending queue according to the sequence of the acquisition time, the image processing unit encrypts two adjacent pictures in the queue, codes generated after the two pictures are preprocessed are arranged in a staggered mode to generate a new code, and the new code is sent. The coding information generated after the coding dislocation has no actual meaning, and is difficult to crack even if being acquired by others; after receiving the dislocation code, the management platform 3 only needs to sort the dislocation code according to a preset decryption program and then generates an original code, so that unencrypted image coding information can be obtained.
The network module 2 sends the digital information of the perception module to the management platform by using a 5G wireless communication network. By utilizing a complex wireless transmission technology and a wireless network architecture owned by a 5G wireless communication technology, the ultra-dense networking technology can improve network coverage, greatly improve system capacity, enable network deployment to be more flexible, and guarantee real-time high-definition transmission of videos collected at the front end while overcoming the problem of network coverage in mountainous areas so as to guarantee that correct judgment is made and a plan is called for rapid command and decision at the first time after hidden dangers occur.
The management platform 3 is used for receiving the data sent by the network module, and performing resource sharing and data online modification; information such as business, data, Internet of things and the like is fused in one platform, so that data sharing and communication among the platforms are facilitated; the management platform 3 includes a data platform for disclosing and managing system data. Authorized staff can monitor and manage system data such as image information of the power transmission line on the management platform through the data platform, and can find dangerous conditions which cannot be found by few machine identification. The management platform 3 also comprises an image recognition unit and an alarm unit, wherein the image recognition unit intelligently recognizes the image information collected by the sensing module to judge whether hidden dangers exist, and if yes, an alarm instruction is output to the alarm unit; and the alarm unit outputs an alarm signal after receiving the alarm instruction of the image identification unit. The intelligent identification of the image identification unit and the perception module forms multi-stage early warning, so that the probability of false judgment and missed judgment of the alarm situation can be reduced. The alarm signal that the alarm unit sent can show on the management platform, and managers can in time take corresponding action after receiving alarm signal through the management platform.
The operation principle is as follows: an image acquisition unit in a perception module 1 records the condition of a line into image information in real time by using an image acquisition device, the image information with strengthened main body information and weakened useless information is obtained after noise reduction and background weakening of an image processing unit, the images are arranged in a queue in sequence and are sent to a management platform 3 through a 5G communication technology after encryption processing, the management platform 3 obtains the line image information according to a preset decryption program and discloses the image information on the management platform 3, a manager can obtain visual information of the line state through the management platform 3, and deletion and modification operation can be carried out on the data on the management platform 3; if the image recognition unit of the management platform 3 detects that the line image has an abnormal condition, the image recognition unit triggers the alarm unit to send an alarm signal to inform a manager to take corresponding measures in time.
