When installing a wired GPS tracker, we sometimes find a "remote fuel cut-off" function. However, this is often followed by the text "This function is to be used in conjunction with a relay". So what is a relay? What does it do and how is it wired? This article will give you the answer.
A. The role of automotive relays.
The remote oil/electricity cut-off relay described in this article is a control relay. It is the equivalent of a switch that draws the armature into the circuit by means of a magnetic field, thus driving the contacts to break the normally closed contacts. In this way, it plays the role of changing the control circuit. It is the key to controlling the circuit on and off.

With the continuous improvement of everyone's living standards, cars have become a vital travel tool for everyone. Therefore, the GPS locator has become the most widely used machine in people's daily life. It has a wide range of applications and is suitable for different groups of people, such as the car rental industry. Many places have production locations for car gps tracker, so many people come to buy them. When you are ready to buy it, you must pay attention to the following knowledge points, otherwise you will not be able to buy your favorite product.
A. Compare the quality of the GPS locator
When we choose a GPS locator, we must learn to compare products. Many people who buy a new GPS tracker will say that the one I used before is better. But this is not correct, because each product is used at a different time and place, and the final result is different. It must be used for a long time to feel the difference between the two GPS locators. Choosing a trusted GPS tracker is a...
There are many GPS tracker manufacturers on the market, but how to choose a suitable for their own, next will teach you how to choose a good GPS tracker.
In terms of hardware(GPS tracker)
1, whether or not there is a battery, charging IC will increase the cost of $0.5, but it will make the battery in the trickle, constant current, constant voltage charging conditions, full automatically cut off the charging circuit, the damage to the battery is the least, not easy to cause battery damage. ERY boiler drum overheating, explosion and other accidents. The cost saving hardware does not need to charge the IC, but instead uses a current limiting resistor to connect the 4.xx voltage directly to the battery. The battery will always be in current-limited charging state. Battery life will be greatly reduced. Prone to bulge, explosion and other accidents. It's easy to have an accident when the phone is plugged into the charger all the time.
2. No matter whether the battery itself has overcurren...
Does GPS have the same life span as cell phones?
What is the reason for the sudden offline display? Next, great-Will GPS trackers takes you to understand these problems.
No matter what kind of product has a life span, you will take that into account when buying appliances such as mobile phones. When buying GPS trackers, I'm sure many of my friends have asked the same question: How long will GPS trackers last? Or how often does the locator need to be replaced?
Perhaps what most consumers are hearing is that regular locators last five to six years. So, does it really take 5-6 years for an electronic product to be continuously updated?
For some wired GPS trackers, as long as they are well maintained and installed, the locator can be used continuously. If you want to use them for 5-6 years, this is no problem. Some of the more advanced manufacturers may try to use better, more durable chips, such as power protection. The GPS trackers will naturally last longer.
As for wireless GPS track...
4g gps tracker
The common means of transportation in modern society has become cars. With the widespread use of cars, the auto loan industry has also ushered in a fast-growing way out. Therefore, for auto loan companies, it is necessary to ensure that the safety of the cars that are loaned out and the credit risks of the customers are within the control, which is indispensable for the help of smart locators. With the development of the Internet, 4G gps tracker have gradually become the preferred intelligent positioning terminal for auto loan companies.
well, the auto loan industry to choose 4G gps tracker benefits mainly have the following points.
1. Danger monitoring, monitoring and warning of irregular behaviors at any time
For the auto loan industry, the risk of a car being mortgaging is that it will become a second mortgage, causing property damage. In order to effectively improve the safety factor of loan vehicles, THE 4G gps tracker can collect the driving data of vehicles in ...
The birth of GPS for the positioning system has been a great help, but also for the car has brought a lot of convenience. The next GPS will take you to understand the KNOWLEDGE of GPS.
The birth of the automobile and many function service configuration, do you like a gas station, navigation systems, etc., said must mention the GPS car navigation, today, there are four parts of the world's navigation system, first of all, America's global positioning system (GPS), which is composed of 24 navigation satellites, the precision of 10 meters, followed by Russia's glonass navigation system, the system is made 24 whoStars. The third is Europe's Galileo navigation system, which has an accuracy of one meter and is a very popular positioning system. The last is China's Beidou navigation System, which consists of five in-orbit synchronous satellites and 30 non-synchronous satellites with a positioning accuracy of 10 meters.
So how did GPS come about? The previous positioning system used...

GPS positioning system has become more and more a helper for fleet management. Its powerful functions bring great convenience to managers, save time and effort, and at the same time save costs to a certain extent, improve business level and efficiency, mainly Effective management of the fleet is achieved through the following functions:
Vehicle positioning function: After selecting the vehicle that the enterprise needs to view, the GPS positioning system automatically maximizes the vehicle position on the map. The vehicle icon flashes rapidly to indicate that the vehicle is running, and the vehicle icon flashes slowly to indicate that the vehicle is stopped.
Real-time tracking function: When the enterprise needs to track a certain vehicle in real time, the GPS positioning system automatically maximizes the current location of the vehicle and the driving trajectory of the first two minutes. The map continuously describes the vehicle to be monitored with blue lines. R...
First of all, it is necessary to understand the working principle of GPS speed measurement and speedometer: After receiving the radio waves of more than 4 satellites and above, the GPS terminal can determine the position of the vehicle and calculate the driving time through the change of position in a very short time. The distance is obtained to obtain the driving speed; the signal of the speedometer comes from the speed sensor on the gearbox or the output shaft, which is synchronized with the rotational speed of the wheel. After the signal is processed, it is sent to the stepping motor pointed by the control pointer in the speedometer to display the current speed to the user.
According to the principle of the speedometer, there are two main reasons for the difference between the speedometer and the actual speed:
The tire pressure of the automobile tire is insufficient or due to wear during use.Its radius gradually decreases. The speedometer's signal is synchronized w...
There are many manufacturers of GPS positioning devices, but not all of them are "a man with professional training". Therefore, we must know how to distinguish between true and false when purchasing GPS positioning device. There are several common senses to know.
1. Civil GPS positioning device with a maximum accuracy of less than 10 meters
The GPS positioning devices we are using now belong to the civilian-grade GPS. (We don't discuss it at the military level for the time being). In the case of good signal (under ideal conditions such as open ground and sunny weather), the positioning accuracy is generally around 10 meters. If it is LBS (base station) positioning, the positioning accuracy is generally between 100 meters and 1000 meters.
GPS positioning accuracy is achieved by a certain algorithm. For the environment at that time, if there are high-rise buildings, interference signal sources, and cloudy weather, the positioning accuracy error will definitely be relatively large. The...
