Characteristics of Underground Pipeline Detector
Characteristics of Underground Pipeline Detector
Most of the underground pipelines are metal materials, which can induce and transmit electromagnetic waves. With its superior performance and flexible and convenient detection methods, the underground pipeline detector has a large number of users in the fields of electric power, telecommunications, water supply, heat, gas, petroleum, chemical industry, urban public utilities and so on, It has played a positive role in improving the pipeline management level of relevant industries in China. The underground pipeline detector is characterized by multi-functional measurement and simple operation. Stable performance, full digital control, sufficient power, long continuous use time, portable design, suitable for field operation. Under the condition of no excavation, it can not only accurately measure the position of buried pipeline, but also accurately locate the damaged point. Even pipelines with branch pipes or forming a network can be effectively detected. Thus, the pipeline network diagram of * * is drawn, which provides strong support for urban construction and pipeline maintenance. Auxiliary functions of underground pipeline detector 1. Automatic adjustment of receiving gain: automatically adjust the gain of the receiver to make the receiver in an optimized state, avoiding the tedious manual adjustment. 2. Sound function: the tone change sent by the receiver through the horn directly reflects the measured signal size. 3. Pipeline state detection: when the transmitter is in injection mode, first detect the insulation resistance and residual voltage of the pipeline, and then apply the signal to the target pipeline. When the insulation resistance on the pipeline is small (close to short circuit to ground), the transmitter will automatically exit this mode. When the residual voltage is large, the transmitter will give an alarm, and the operator shall immediately stop loading the signal and turn off the transmitter. 4. Battery power detection: real-time detection of battery power. When the power is low to the protection value, an alarm will be sent out and the battery will be shut down automatically. 5. Power saving function: after the transmitter is turned on for about 30 seconds without pressing other keys, and after the receiver is turned on, if other keys are not pressed for about 10 minutes, the machine will shut down automatically to save battery power.
How to Use the Cable Identifier and How to Judge Whether the Cable Is Live
How to Use the Cable Identifier and How to Judge Whether the Cable Is Live
How does the cable identifier judge whether the cable is live? First: why should we judge that the cable is live: as an important instrument of power cable detection instrument, cable identification instrument has been used more and more widely. When there are multiple cables in the cable trench, it is necessary to identify a specific power-off cable, calibrate, move or cut off the cable, and other cables in the cable trench operate live, so the cable identification instrument shall be used for cable identification. Second: easy to use: compared with the cable fault tester, the use of the cable identification instrument is relatively simple. It is easier to use it by reading the instructions. Third: test example: since the cable shielding layer is usually connected to the ground, if other cables are also connected to the public ground in the cable bundle, the black output jack on the generator can be connected to the public ground, The return current is distributed in several cable shielding layers, and the return current is divided into many tributaries, which means that the difference current of the identified cable is large and the useful signal is clear. "Difference" means that the output current and its divided return current are in the same channel. As shown in Figure 4, there are 5 cables in Figure 4. Cable 4 needs to be identified. The "output current" of the cables to be identified is 20A. Assuming that the return current is evenly distributed among the shielding layers of all cables, there should be a return current of 4A in the cable to be measured. The difference in the cable to be identified is: 20A (output) - 4a (return) = 16A (difference). How to use the cable identification instrument I. working method of the cable identification instrument: the transmitter (host) is powered by 220V AC power supply, which is used for the power-off The cable to be identified, plus a fixed period, unipolar DC pulse signal. The output line of the transmitter is connected to the cable core and the grounding point or ground nail. The armor of the cable is disconnected from the earth, and the core is connected to the grounding point or ground nail at the far end. The loop can conduct pulse current, which can be read out by the meter on the receiver of the identifier. The current is determined by the loop resistance, and the loop resistance should be as small as possible. The wiring diagram of the identifier is shown in Figure 2. Note: during field use, if the grounding resistance is too small, the output current of the transmitter will also be large when the output adjustment knob is turned back to zero, and the protection circuit in the transmitter will act (shown as a small fast swing of the meter). At this time, the randomly configured 1 ohm 20W high-power resistor can be connected in series in the transmitter circuit. After the transmitter and receiver start working normally, the voltage induced in the sensor coil is displayed in the receiver header. The pointer swing direction of the header can display the current direction, that is, only the cable with current flowing out, the pointer deflects and swings greatly. This is the cable to be found. For all other cables, only the return current flows, the pointer deflects in the opposite direction and the swing is very small. The output adjustment knob on the receiver can adjust the signal strength. 2、 Wiring mode: 1. Before the test, cut off the tested cable, and the surrounding environment shall be in a safe state. 2. The generator is connected with the tested cable, and the red clip is connected with one or several cores of the identified cable. Connect the black clip to the ground nail. 3. Connect the core wire at the far end of the cable to the ground nail. 4. Disconnect the armor at both ends of the cable from the ground wire. 5. Plug the power cord into the power outlet. 3、 Identify the cable through the loop test. 1. In order to ensure the normal use of the instrument, pay attention to setting the test loop. 2. Connect the red output jack to the core of the cable to be identified, connect the black output jack to the ground, and connect the cable core to the ground at the far end. As shown in Figure 3, 3. The output current flows to the far end in the direction of the arrow in the cable, and all cores of the identified cable can be connected together through the earth return generator to obtain a clearer signal.

Home Robots Can Be Hacked to Spy and Attack Their Owners and This Clip of a Mini Android Wielding a
THIS adorable humanoid robot can be programmed to stab you when you're not looking.UBTech's home android Alpha 2 - which has proved a particular hit in the US - was hacked by security experts who used the experiment as way to expose how vulnerable the technology we are allowing into our homes is.In the clip, little Alpha 2 can be seen furiously stabbing a tomato with a screwdriver after researchers at security company IOActive managed to hack the software that controls it.They were also able to turn two other popular robot brands, NAO and Pepper, to capture video and audio as they manoeuvred around a home and send it to whoever they wanted.Factory robots could also be hacked, they warned.According to the boffins, a brand of industrial robots called Cobots that work alongside humans, are a potential hazard.They usually include certain safety and collision detection technologies to prevent possible injury from use of the products but an experiment has proven thatthese robots can be hacked remotely and used to injure humans around them."Even running at slow speeds, their force is more than sufficient to cause a skull fracture," IOActive wrote in a statement.Bride-to-be Regina Allen Elsea, 20, was recently crushed to death by a robot just two weeks before she was due to marry the love of her life.This research follows an open letter to the UN from tech leaders such as Elon Musk urging it to ban killer robots for warfare.But IOActivewarned that we also need to evaluate the security and dangers of robotic devices that are appearing in our homes and workplaces.Lucas Apa, IOActive principal security consultant, said: "The brightest minds in the word have spoken out this week about the potential dangers of robots, but I would argue that it isn't just the use of robots in the defence industry we need to worry about, it's also the ones in our homes and factories."I have no doubt that devices used by armed forces will be infinitely better secured than the devices weve tested but nothing is fool proof."Tech leaders already want killer robots banned for doing what theyre meant to do. Just imagine if they go rogue or do what malicious hackers tell them to do instead."We pay for your stories! Do you have a story for The Sun Online news team?

Cable Grounding Troubleshooting and Precautions
Cable Grounding Troubleshooting and Precautions
There are three main reasons for cable grounding fault. First, cable manufacturing defects are unqualified products; Second, poor operating environment, natural aging and external damage; Third, the installation is not standardized and the wiring is rough. There is only one root cause of grounding fault --- the insulating material of the cable. China's large-scale ground power stations are generally located in the West. These places are generally desert, saline alkali land, large temperature difference in the daytime, serious rat damage and very humid environment. For cable buried laying, the filling and excavation requirements of cable trench are relatively high; The operating environment of the distributed power station cable is no better than that of the above ground. The cable will bear a very high temperature, which is measured and controlled by technicians. The roof temperature can even reach the high temperature of 100-110 ℃. The fire and flame retardant requirements of the cable and the high temperature have a great impact on the insulation breakdown voltage of the cable. Therefore, the following points should be considered in the type selection design: 1. The insulation performance of the cable 2. The moisture-proof, cold proof and weather resistance of the cable 3. The heat-resistant and flame-retardant performance of the cable 4. The laying mode of the cable 5. The conductor material of the cable (copper core, aluminum alloy core and aluminum core) 6. The Section specification of the cable

Why CCTV Monitor Testers Is the Better of the Other
CCV testers, also known as LCD field monitors or CCTV field monitors, provide installers with an ideal solution that allows them to view, calibrate and correct the camera's video feed in real time based on the additional features that they provide. The basic feature of a CCTV tester is an LCD display (25 inch x 3.5 inch diagonal) that allows the installer to view a camera feed on the spot. If the camera is set up in a separate area, the installer must run the feed to refine the settings.Other features of video calibration include video test patterns, the brightness, contrast and saturation adjustment, video signal intensity testing and support for PAL and NTSC video. Another aspect of the functionality that should not be overlooked by a CCTV tester is the ability to work with analog and IP cameras.If you are a professional installer, you probably have heard of closed circuit television testers (also called LCD field monitors, CCTV video testers, CCTV camera testers or IP camera testers). The ability of CCTV testers to work with both analogue and IP cameras is particularly important as digital surveillance cameras become increasingly popular. A closed circuit TV tester is a handy tool for professional CCTV installers and do-it-yourselfers to set up and configure CCTV cameras from any source.NKTech's 3.5-inch CCTV Tester is a portable device designed to install and maintain existing on-site CCTV video surveillance systems.

Disaster management uses CCTV cameras to allow emergency services and responders to assess and monitor events in real time and video the situation to the disaster management team.The CCV technology was first developed in 1942 by German scientists to monitor the launch of the V2 rocket. With road surveillance cameras and traffic lights, cities can monitor people, collect traffic statistics, evidence and speed. The legacy of the IoT (AOT) is the Chicago Initiative, which collects real-time weather and environmental data in Chicago.It is essential to constantly clean, pre-test and calibrate CCTV testers. To ensure accurate testing, it is important to study CCTV systems and conduct tests with tools that measure the performance of multiple indicators. A man on a ladder who manipulates a camera not only walks around, he measures the video signal and evaluates the running camera.This is a quick test for the effect of measuring the input and output video signal by examining a device. The same man who climbs a ladder and manipulates a camera can also do so with other video devices such as video splitters, disconnectors, switches, route switches, cable connectors, etc.With this connector we can connect the camera to its output and check the level of the video signal. It's a handy solution for men who have a ladder to manipulate the camera. You can connect the cable to the LED cable of the monitor to check the signal.Contrary to the impression, the 1.2V voltage causes many problems when we supply the camera with a long cable. The voltage loss caused by the greater resistance of the cable reduces the value of the camera clamp and interferes with proper operation.A tester with a USB port can charge mobile devices, but does not have a data interface.

Application Scope of Underground Pipeline Detector
Application Scope of Underground Pipeline Detector
Underground pipeline detection method is one of the commonly used geophysical detection methods. Generally, there are two methods: the first is to use DC detection method for geophysical detection. Specifically, in the process of detection, two power supply electrodes are mainly used for corresponding DC power supply, and a power supply cycle is formed underground, Through the circulating power supply to ensure the measurement of underground current density, we can effectively judge the specific location of buried metal pipelines. Generally, the detection using this method is mainly based on the corresponding metal pipeline. This method is based on the difference of current density. Generally, the most commonly used method of this technology is the high-density resistivity method for corresponding measurement. For example, during the measurement of underground pipelines in a city, the direct current detection method is used for geophysical detection, and the location of metal pipelines in concrete materials is effectively found; The second method is to use the alternating current detection method for geophysical detection. Specifically, in the process of detection, the corresponding conductivity and corresponding magnetic transformation generated by the alternating current in the process of magnetic field transformation are mainly used. In the process of detection, the corresponding underground pipelines are detected through the magnetic field formed by the alternating current, So as to effectively ensure the accuracy of underground pipeline detection. Through the use of alternating current detection method for geophysical exploration, we can effectively find the differences between underground media, and find out the specific problems and sources of these differences through the analysis of these differences. Specifically, these methods have the characteristics of uniform measurement and long working time. They are one of the effective means for underground pipeline detection.
