Where is the bicycle sharing gps installed?

Abstract: How to use gps to supply power for bicycle sharing? Bicycle sharing relies on solar energy to generate electricity, so it will be more labor-saving. It is said that there is a built-in 6000mAh battery. Where can I install bicycle sharing gps? Bicycle shared lock integrates embedded chip, GPS module and Internet of Things SIM card. How do bicycles share gps and bicycles share gps to supply power? Where is the bicycle sharing gps installed?

How does bicycle sharing gps provide power for positioning?

Netizen speculated that:

1. Traffic: mobike should have a built-in GPS+GSM module, and the traffic fee should be discussed separately with mobile and telecommunications. The amount of data sent by each hitchhiking is very limited, so the traffic fee should be very economical.

2. Positioning: GPS is used for outdoor positioning, AGPS is used for indoor positioning and GSM is used for auxiliary positioning. Positioning is a power-consuming function, which mainly reports errors when unlocking and locking.

3. Power supply: old bicycles rely on manpower to generate electricity, and bicycles have built-in generators; Lite is solar power, so it will be more labor-saving. It is said that the built-in 6000mAh battery is almost equal to the 8-cell battery of the notebook.

Where can I install bicycle sharing gps? (Take mobike as an example)

Mobike built a stable and efficient "CPU" brain processor through embedded chips, and used GPS module to achieve the best performance. ...

After comparison, Bian Xiao thinks that mobike has done well in this respect, so he takes mobike as an example to discuss.

The use of explosion-proof tires, chainless transmission and all-aluminum stainless steel body: it belongs to original industrial design and production, and does not show the concept of intelligent hardware.

Embedded chip, GPS module and Internet of Things SIM card are integrated in the body lock, which is convenient for mobike to monitor the specific position of the bicycle on the road. The specific analysis is as follows.

1, embedded chip: according to the application scope and processing capacity of the processor, it can be divided into embedded microprocessor, embedded microcontroller, embedded DSP processor and embedded system on chip. A little silly, haha.

1. 1, embedded microprocessor unit (MPU): The embedded microprocessor is evolved from the CPU in a general-purpose computer. It is characterized by more than 32-bit processors and high performance, and of course its price is correspondingly higher. However, different from the computer processor, in the actual embedded application, only the functional hardware closely related to the embedded application is kept, and other redundant functional components are removed to achieve the special requirements of the embedded application with the lowest power consumption and resources. Compared with industrial control computer, embedded microprocessor has the advantages of small size, light weight, low cost and high reliability.

1.2, embedded microcontroller unit (MCU): The typical representative of embedded microcontroller is single chip microcomputer. There are various necessary functions and peripherals, such as ROM/EPROM, RAM, bus, bus logic, timer/counter, watchdog, I/O, serial port, PWM output, A/D, D/A, FlashRAM, EEPROM, etc. Compared with embedded microprocessor, the biggest feature of microcontroller is monolithic and its size is greatly reduced, thus reducing power consumption and cost and improving reliability. Microcontroller is the mainstream of embedded system industry at present. Recently, Avr microcontroller produced by Atmel has a high cost performance due to the integration of FPGA and other devices, which will certainly promote the higher development of microcontroller.

1.3, Embedded Digital Signal Processor (EDSP): DSP processor is specially designed for signal processing, with high compilation efficiency and instruction execution speed. DSP has been widely used in digital filtering, FFT, spectrum analysis and other instruments.

1.4, embedded system-on-chip: SOC pursues the most inclusive integrated device of product system, which is one of the hot spots in embedded application field at present. The biggest feature of SOC is the seamless combination of software and hardware, and the code module of operating system is directly embedded in the processor chip. Moreover, SOC is very comprehensive, and a complex system is realized on a silicon chip with VHDL and other hardware description languages. Because most of the system components are inside the system, the whole system is particularly simple, which not only reduces the volume and power consumption of the system, but also improves the reliability and design production efficiency of the system. SOC chip also plays an important role in applications such as sound, image, film and television, network and system logic.

2.GPS module: GPS positioning is widely known, so what does GPS module mean?

GPS module is an integrated circuit that integrates RF chip, baseband chip, core CPU and related peripheral circuits. At present, the GPS chip of GPS module with the largest market share in the world is mainly SiRFIII series. Because the chipset used by GPS module is different, the performance and price are different. The performance of GPS module using SIRF third-generation chipset is the best, and the price is much more expensive than that using GPS chipset such as MTK or MSTAR. At this stage, the chip is continuously upgraded, such as sirf4, and then sirf5, which improves the overall sensitivity, shortens the positioning time, and helps customers quickly enter the positioning application state.

3. Internet of Things SIM card: The application of SIM in daily life is no stranger. What is the Internet of Things SIM?

The Internet of Things card is connected to the wireless network through an interface such as a SIM card, a sensor and a QR code. Installed on various objects, it can realize the communication and dialogue between people and things, things and things. The Internet of Things has three characteristics: scale, liquidity and security. China Mobile's Internet of Things service is based on China mobile communication network, providing customers with personalized, intelligent and information-based Internet of Things applications. Is this a clearer understanding?
