Detailed Description

The present invention will be described in further detail with reference to the following embodiments, which are illustrative, not restrictive, and the scope of the invention should not be limited thereto.

A positioning device comprises a CPU-communication module, a positioning module, a gravity acceleration sensor, a battery, an SIM card seat, an LED indicator light, a reset hole and a key, wherein the positioning module, the gravity acceleration sensor, the battery, the SIM card seat, the LED indicator light, the reset hole and the key are respectively connected with the CPU-communication module. The battery is connected with the voltage conversion chip, and the voltage conversion chip is connected with the positioning module.

The CPU and the communication module select MT6260, and the MT6260 comprises a SIM interface, a UART interface, a radio frequency interface, an I2C interface, a power supply interface and a keyboard interface. The I2C interface is connected with a gravity acceleration sensor. The SIM interface is connected with the 6pinSIM card seat. The UART interface is connected with the positioning module. The keyboard interface is connected with the keys, and the power supply interface supplies power through the battery. In addition, the GPIO pin of the MT6260 is also used, and an external LED is used for displaying the states of GSM signals, positioning and electric quantity, thereby being convenient for users to use.

The positioning module adopts an eighth generation product UBLOX-M8030 of UBLOX company.

In order to detect illegal displacement, reduce the power consumption of terminal equipment and prolong normal use time, the position of the equipment adopts an intelligent reporting mode, when the terminal detects that the equipment is in an illegal motion state, the position of the terminal is automatically reported to a platform, and when the equipment is in a static state within a period of time, a positioning module is closed, GPRS data connection is disconnected, and the position reporting to the platform is stopped, so that a gravity acceleration sensor is needed to detect the state of the equipment, and in the scheme, an mKube series MotionSensor product MC3236 is selected.

The MT6260 supports internal charge management, which converts the 5V output from the charger into 4.2V for charging the battery. The voltage conversion chip is used for converting the voltage (4.2V-3.7V) of the battery into 3.3V, the positioning module is powered, and the ME6211C33R5GN chip is adopted due to the small voltage difference.

The battery mainly considers the standby time requirement and the temperature environment requirement brought by capacity, so a ternary lithium battery is selected.
