Global Positioning System (GPS) trackers are portable terminal devices manufactured by related technology companies for object positioning. It's a finished product, and with the help of the relevant location platform or APP, we can get accurate location information.
As the name suggests, lte gps tracker is a gps location device dedicated to the automotive sector that allows fleet managers, parents, and car owners to monitor and track the location of their cars and trucks. Generally speaking, lte gps tracker for cars not only provides the instantaneous speed and location data of the car in real time, but also provides the location data of the car. Most companies in order to make the car gps tracker to solve the needs of more owners, they will expand many practical functions, such as historical location data query, so that the owner of the car to better grasp the trajectory of the car to statistics over a period of time, the car's driving situation, just like a lot of step counting software now, can replay your running route.
The real-time alarm function can prevent your car from being stolen and grasp the abnormal information of the car in real time, and even some car gps trackers can be operated without fuel. You can imagine, you are the manager of the fleet company, when you find that one of your employees driving a car deviates from the normal driving route, the employees are driving the car, at this time, you only need to use the mobile APP, can interrupt the car, this is how cool function!
With the improvement of technology level, we believe that car gps trackers will have more rich functions in the future. Mobile communication company is currently focusing on the development and design of a new car GPS locator, please look forward to it!
After saying the purpose of lte gps tracker, let's take a look at how lte gps tracker works.
How does a GPS tracking device work?
lte gps tracker uses a network of GPS satellites to find where devices need to be located. The basic principle is that the lte gps tracker uses a trilateral measurement method to determine its physical location, and the premise of determining the location needs to be worth its distance from three GPS satellites. Then, by using the coordinate method, we know exactly where the device is. The same principle applies to personal in-car navigation systems.
However, there are differences between GPS and car navigation systems. The difference between a GPS locator and a car navigation system is that a navigation system gives you location and driving directions, while a tracker can record your driving habits or play your location in real time.
What the in-car navigation system serves is that we don't need to install other facilities in order to find individuals who turn on navigation in a certain location. GPS locator services are mainly leaders of fleet management companies, as well as individuals who need real-time detection of object movement information, GPS locator can be used as a carrier of information channels, requiring us to install a SIM card for the device.
Car tracking locator application scenario?
The main purpose of GPS car tracking devices is to let you know where your vehicle is at any time, and it is very effective in some specific scenarios. For example, if your car is stolen but you have a tracker installed, you can provide the police with its exact location, which will help them solve the crime quickly and recover your car.
In fleet management. In order to ensure the efficient operation of corporate vehicles, and prevent employees from using vehicles for personal use, GPS car tracker is a very effective solution, which can help enterprises efficiently manage assets and save labor costs, because it only requires a few GPS car positioning devices.

fume sucker non-core indicators operating temperature should be considered according to long-term operating temperature, in order to avoid condensation, generally should keep fume sucker non-core indicators smoke temperature above the dew point 15 ~ 20℃. When purifying the high temperature gas whose temperature is close to the dew point, the relative humidity of the gas should be reduced by indirect heating or by mixing the high temperature gas.
When running fume sucker non-core indicators, the status of the differential pressure system should be observed to see if there is any fault. The pressure difference value of fume sucker non-core indicators pressure difference system is accurately recorded. If the pressure difference is suddenly found during the recording process, it is necessary to check the filter bag to see whether there is blockage or dust compaction. At the same time, the ash cleaning system should be accurately checked. Avoid excessive accumulation of ash in the ash hopper. If there is a sharp drop during the recording process, it may be that the filter bag is damaged or is falling off.
Below, teach you to improve fume sucker non-core indicators cleaning speed methods:
In the use of fume sucker non-core indicators, it is necessary to prevent the gas from cooling below the dew point in the bag room, especially when using fume sucker non-core indicators equipment under negative pressure.
Second, because its shell often has air leakage, so that the bag room gas temperature is lower than the dew point, the filter bag will be damp, resulting in dust is not loose, but sticky attached to the filter bag, the fabric hole blocked, resulting in ash failure, so that the dust collector pressure drop is too large, can not continue to operate, some can not dust paste bag.
fume sucker non-core indicators a branch lift valve is closed, the filter air is cut off, and then the electromagnetic pulse valve is opened, the compressed air expands in the upper box in a short time, and rushes into the filter bag, so that the filter bag expands and deforms to produce vibration, and under the action of reverse airflow. Dust attached to the outer surface of the filter bag is stripped and dropped into the ash hopper.
Fourth, after the cleaning is completed, the electromagnetic pulse valve is closed, the lifting valve is opened, and the chamber is restored to the filtering state. Cleaning each chamber in turn, from the beginning of room cleaning to the next cleaning for a cleaning cycle. The dust trapped by the filtration and ash cleaning work falls into the ash hopper, and then is centrally discharged by the ash discharging device at the mouth of the ash hopper.
fume sucker non-core indicators With the extension of filtration time, the dust layer on the filter bag continues to accumulate, the resistance of the dust removal equipment continues to rise, when the resistance of the equipment rises to the set value, the cleaning device begins to clean.
fume sucker non-core indicators equipment The equipment that separates dust from flue gas is called dust collector or dust removal equipment. The performance of the dust collector is expressed by the amount of gas that can be processed, the resistance loss of gas passing through the dust collector and the dust removal rate.
The price of dust collector, operation and maintenance costs, good and short service life and the difficulty of operation management are also important factors to consider its performance. Dust collector is a common facility in boiler and industrial production.
