Objective: what do you want to be an electronic map, to achieve a certain range any object (with this equipment, and moving) displayed on the electronic map (like navigation, unlike the navigation display multiple objects at the same time the dynamic location), their design ideas: consists of two systems: transmitting and receiving system, Gps module to MCU to wireless transmitting module, launch system (launch system: the Gps to obtain the latitude and longitude, speed, time and other information, through the microcontroller programming, wireless transmitting module to launch or broadcast). Receiving module to single chip microcomputer to electronic map (display) receiving display system (receiving display system: the launch of the broadcast information module receiving other objects, by SCM compilation, then feedback to the electronic map, the electronic map display the received multiple object location information), requirements: 1, the transmission distance is more than 500 metres (obstacles have adapt to the environment), 1000 m; 2, no late fee (the absence of other schemes, then consider using mobile network); 3, the sending and receiving GPS location information must be continuous, real-time updates, please master to give directions, this idea is feasible? If there is a better idea (plan)?

Please master to give directions! Thank you very much!
CodePudding user response:
A Gps module is done directly,
CodePudding user response:
The Gps module
CodePudding user response:
//a 500 m distance, no follow-up expenses, not possible,
//is 315 m, but also more than 1 w transmission power, without the ac for you a cup of tea,
CodePudding user response:
Warrior advice please! Thank you very much!
CodePudding user response:
GPS module plus LORA, LORA narrow-band high sensitivity, 500-1000 - m should do not have what problem,
CodePudding user response:
Agree with the 6th floor thinking! GPS + LORA
Channel 1: LORA, 433 MHZ, free application, sending and receiving in the accessibility theory 3 kilometers, the elder brother of the atom has a version of the stamp hole LORA module, small, using a serial port to send and receive, good programming
2: receiving module, MCU on the map? With what type of chip, how to answer the map? Can share, also have a piece of my recent project, and you are same, has adjusted the 10-inch screen output in Chinese, but I don't know how on the map
