Accidents are highly likely to cause serious casualties and damage to property. Many cities in the country have been actively exploring ways of governance in recent years。
On the night of late july, a group of search engineers were followed by a reporter from the night's report of lamb town to carry out an in-situ detection mission in the streets of guangzhou. Through interviews, journalists were informed of an advanced science and technology that can be detected with extreme speed — the “ct” of the road, which exposes the danger hidden in the depths。
It is known that guangzhou has recently been caught in the cross-cutting spiral. The safe running of cities has been effectively secured by a previously undetectable set of pitfalls that have been discovered and managed before the accident had occurred, under the “thinking” of technology enterprises and the “playing of government departments. In addition to the introduction of technology, our research units and enterprises are actively studying the domesticization of relevant technologies。
Mine detector
Late in the night of 29 july, a commercial vehicle was shuttled across the border between the huang po and tianhe districts of guangzhou city. In contrast to the normal vehicle, the commercial vehicle had a flat-tangled device on its tail; the rear window of the vehicle had arrows to avoid the lights and to alert other vehicles to allow them to operate. Engineers in the car, who keep an eye on the computer screen, observe the transmission of tail devices to every radar data in front of the computer screen。
"we're working on an underground trap detection." the party storm from shenzhen andre space technology ltd. Was part of the team of interior engineers. He told journalists that the equipment on the back of a commercial car could be detected at a maximum speed of 100 km/hour for a three-dimensional mine detector capable of detecting a 3-metre radius of the ground. Through commercial vehicle towing, radars allow full cover detection of motor vehicle tracks. On top of the back of the commercial car, there is a positioning system and a high-resolution camera system, where the location determined by the above-mentioned equipment and the high-resolution video data are transmitted back to the detection station in the vehicle。
“as a result of the undamaged scanning of 3d mine detection equipment, we are able to detect the distribution of the hazard and the degree of harm caused by the pitfalls that have taken place.” the party team informed the journalist that since july 2018, when the company that took up duty took part in the site inspection, he had travelled with 3d mine detection vehicles to various parts of the country. He and his colleagues had detected hundreds of underground holes that could be trapped and had been notified of the governance efforts。
But the radar echoes to determine what's at stake
Journalists followed the party's campaign to document how engineers had discovered the pitfall。
A mine surveyer carrying engineers and journalists traveled through the streets of guangzhou. In the course of the journey, journalists saw the workstation constantly receiving underground echoes. “a return signal does not necessarily mean that the ground is in danger.” party attacks tell journalists that many cities have complex underground structures and numerous underground facilities, such as pipelines, well-covered facilities, etc. Once cleared, 3d mines can be found both in the ground and in normal underground facilities. Combined with the pattern of the echo signal and the road through which the radar vehicle passed, the party sprints determined that most of the echo was related to the well cover facility。
“if we are to be more clear about what's going on below the surface, we have to analyse the 3d radar data.” party impulses indicate that they upload radar, positioning systems and high-resolution video data back to the company's analysis system. A system with artificial intelligence allows for rapid and large-scale analysis of radar echo information, determination of normal or abnormal underground holes, determination of the type and distribution of underground hazards on roads, etc. In the case of an abnormal underground hole, the system produces a three-dimensional model of an empty hole, in addition to indicating where it occurred。
“we will send a review team back to the site for review as analysed through the artificial intelligence analysis system.” the party's sprinting team colleagues will use portable 2-d radar to review the scan and, if necessary, also core the site, using a perforated camera to film an inner-space video of the subterranean hazard, so as to exclude interference from normal man-made underground facilities. Once the scale and location of the hazard is clearly defined, they will notify the road manager or emergency management department of the location of the hazard in a timely manner。
“if the time for later review is not calculated, we can, in a short period of time, complete the steps from 3d mine detection to detection of the danger.” party sprints told journalists that experienced engineers could immediately identify the location of the hazard on site by detecting the mine back. For further “diagnosis”, engineers are required to upload radar scan results to the system analysis. It takes only one to two hours from upload to analysis of the results。
There was nothing we could do, and now there's something we can do
An accident is a governance challenge for many cities, including guangzhou. A variety of factors, such as the clandestine nature of the underground earth column, leaking erosion for drainage pipes, construction of a subway shield and construction disturbance of a large base pit, all lead to accidents。
On 1 december 2019, the western and western road in guangzhou, which resulted in the loss of vehicles for the loss of life and injuries, was caught in an accident that drew the attention of guangzhou to the underlying problems of governance. From december 2019 to july 2020, guangzhou was still caught up in accidents from time to time. Compared to the previous authorities, the presence of landmines has now allowed them to “do what they can”。
Journalists have been informed by the guangzhou city emergency management authority that since january 2020, in the guangzhou city districts of haiju, tianhe, baekyun and south sand, territorial authorities have conducted mine detection operations in high-risk locations, many of which have been identified and promptly repaired. The reports from the guangzhou city emergency management agency were viewed, and all of them were found to be at risk, with the involvement of third parties with mine detection techniques, without exception, by the territorial authorities。
According to the party, in the early hours of 14 july, he completed a radar expedition in guangzhou, uploading the amount of data from the site to the enterprise's artificial intelligence analysis platform. Following an on-site review, the party members and colleagues immediately contacted the huang po district establishment. Before the early peak of the day, the hoang poi district housing authority blocked areas in danger. Upon the identification of the pitfalls associated with the break-up of underground sewage pipes and the erosion of earth bodies, the huang po district water authority immediately carried out emergency repairs, not only to repair the break-down sewage pipes, but also to fill them properly with the associated pitfalls, thus preventing accidents from occurring。
“we are inviting companies with earth-detection technology to carry out experiments in the yellow plum area in preparation for the next normalization exercise.” in guangzhou, the relevant officials of the department of construction of the hoang pil district informed journalists that, in view of the certification, the methods used by the enterprises to locate the sites were highly technical. In addition to the market for bountiful goods, other hazards have been discovered. The pitfalls discovered through radar detection techniques are now all under control。
As a result of the fact that guangzhou is still a “new technology”, guangzhou's functional units are well-versed in the brain. Access to the procurement platform of the government departments of guangzhou city and guangzhou, journalists found that the districts of yutsu and tang yu have been involved in the management of underground hazards on important roads in the area and the procurement of technical mine detection services。
Three-dimensional ground exploration technology is accelerating national production
“everytime i see a story in the news, i'm worried. It's comforting for me to find out where it's coming from.” the party argued that, as a research engineer, he wanted to work for each city of his own to find as much danger as possible. When you see the pits you discover being dealt with, you feel much better and drive。
“radar exploration technology is constantly being updated, taking into account practical applications and local needs.” according to the party, the nationalization of advanced technology is the direction of his enterprise. Although the 3d mine detector is still dependent on imports, vehicle-borne workstations have been improved on the import system by company technicians. An artificial intelligence analysis system to help “identify” the pitfalls is also developed by enterprises. The system allows for the rapid analysis of three-dimensional mass detection data, paving the way for the application of three-dimensional mine detection to the detection of underground hazards on large-scale roads at the city level。
“recommends that all parts of the country should be able to pay attention to underground areas where underground construction is intensive.” the party's rush indicates that the long-used underground pipeline routes are places where he normally finds himself in more danger. Underground works, such as subways and subsurface space projects, which are under way or newly built, are also the more frequent places of exposure. He suggested that cities in various parts of the country should be examined from these more dangerous places, so that accidents that occurred in unknown places and places could be dealt with before they occurred, in order to guarantee safe road travel。
