I want to install a cheap car tracking device for my car, but I find that there are too many varieties. Don't know which one works? Afraid of being cheated? Do you face such chaos? Not in a hurry!
1. What is cheap car tracking device
The first thing to know is that gps positioning in a car is not the same as gps navigation in a car. Although they sound similar, they are two different things.
The GPS location of the car is based on the GPS locator installed on the car, and then the vehicle location data is transmitted to the vehicle monitoring platform through the communication network, and then you, your family and friends can remotely check the location status information of the vehicle. Simply put, it is used to locate vehicles so that you can find them anywhere, anytime.
In-car GPS navigation is when you have a destination, but don't know how to get there. At this point, you can use the GPS navigation device. After setting the destination on the navigation device, it will provide you with some routes. You can choose it. The right way is good.
2. Working principle of cheap car tracking device
Vehicle GPS positioning system consists of three parts: GPS terminal device, communication network (namely SIM card traffic card) and GPS monitoring platform.
3. GPS terminal equipment
GPS terminals belong to hardware devices, which can be divided into wired devices and wireless devices. Its shape and size are different. Whether wired or wireless, installation is usually relatively simple. The GPS terminal is the information receiving terminal of the cheap car tracking device system, which is used to receive and execute the satellite signals and commands issued by the monitoring platform.
The wired gps terminal is connected to the car battery and powered by the battery, which can realize 24-hour real-time positioning and tracking.
The wireless GPS terminal has its own power supply, which is usually timed positioning and sends the location information to the owner monitoring platform on time according to the time interval set by the owner. The advantage of wireless GPS terminal is that it does not need wiring, as long as it does not block the signal, it can be installed anywhere in the car, and the extra long standby time is hidden, which is simple and convenient.
4. Communication Network (SIM card)
In fact, the communication network described in this article is mainly used for SIM cards in terminal devices. The SIM card is used to upload data. You can query vehicle location data on the monitoring platform. It relies on a SIM card to transmit data to the platform. If the SIM card is damaged, overdue, or the area signal is weak, it will result in the number of locations the vehicle's GPS locates
The data will be biased.
5. Vehicle monitoring platform
Vehicle monitoring platform is the display end of vehicle gps position information. Owners use monitoring platforms to check the condition of their vehicles wherever and wherever they are.
Vehicle monitoring platform includes PC terminal, mobile terminal and web site online inspection car. After the platform receives the data returned by the equipment, the data will be displayed on the map of the monitoring platform, and the owner can view the track playback directly or select a certain period of time. Or it's managing data like mileage statistics. The platform also plays an important role in big data acquisition and remote operation of devices. For example, the remote terminal issues commands to power off the vehicle and remotely lock the vehicle, and also sets the vehicle's speed limit value and usage area on the platform. Driving route, driving time, etc.
For gps vehicle positioning system, any problem in the above three links will affect the normal positioning of the equipment.
