Detailed Description

The following description will further describe a preferred embodiment of the present invention with reference to fig. 1, including a core board structure disposed inside a shell structure, where the shell structure is composed of a front cover 1, a main shell 2, a rear cover 3, and a waterproof cable head 4, the front cover 1, the rear cover 3 and the main shell 2 are assembled by screws 21, and the waterproof cable head 4 is fixed on the rear cover 3; the shell structure is used for installing the core plate structure and the battery module and leading out two antenna interfaces and data interfaces; the surface of the main shell 2 is also added with necessary marks such as company Logo, product model and serial number in a silk-screen or sticking mode.

A sealing ring 22 with a sealing function is arranged between the front cover 1, the rear cover 3 and the main shell 2;

the core plate structure constitute by lithium cell 6, GSM antenna 7, GNSS orientation module 8, the pilot lamp 9 of being connected with PCB board 5 respectively, GSM antenna 7, GNSS orientation module 8, pilot lamp 9 are fixed on protecgulum 1.

The core board structure realizes data acquisition and forwarding, power monitoring and management functions and the like by the main control module:

the main control module is a core part of an intelligent terminal RTU of the Internet of things and comprises a main control chip, an SPI FLASH, an MEMS accelerometer and a JTAG interface for debugging. The main control chip is realized by MCU or micro MPU, and has several operation modes of work, low power consumption work, sleep and the like. The MCU based on the ARM Cortex-M kernel is selected for realization in consideration of low cost, low power consumption, easy development, sufficient resources and other factors. The ARM chip is externally connected with an independent watchdog reset chip and is used for resetting during power-on and monitoring program operation. The independent watchdog reset function is similar to the internal watchdog reset function, and the independent watchdog circuit is used for verification in the debugging stage for the reservation function.

The communication module supports functions of wireless internet access, short messages and the like, and performs data communication and interaction with the monitoring service platform under the condition of an external antenna. The main control module is interconnected with the communication module through a UART serial port, controls and transmits data to the communication module through AT instructions, and simultaneously needs to manage the communication module so as to meet the requirement of low power consumption.

The communication module also needs to realize a remote wake-up function, and the communication module supports a short message wake-up function. The communication module can not be powered off, the monitoring service platform waits for the short message to be awakened after entering the sleep mode, and sends the short message to the communication module for awakening; after the communication module is awakened, the level of an output pin of the module RI is pulled down for 120ms, and the master control MCU is awakened through the level pulling down, so that the remote awakening function is realized. If the power supply voltage of the communication module is low or the short message cannot be received after power failure, the remote awakening function cannot be realized, and the main control MCU is required to awaken the communication module regularly.

The GNSS positioning module 8 receives a navigation satellite signal mainly through an external active GNSS antenna, processes the received signal to obtain longitude and latitude, speed information and current time service information of the beacon light, completes real-time positioning of the running state of the beacon light, and transmits the obtained information to the main control module. The intelligent terminal on the RTU requires that the positioning accuracy is in the meter level, and the positioning result output frequency supports more than 10Hz, therefore requires that the GNSS positioning module 8 has RTD or even RTK positioning ability. The GSM antenna 7 is an external independent component, connected to the GSM antenna interface, and used for wireless transceiving of data signals.

Waterproof cable head

4 and 6 electric connection of lithium cell. The lithium battery 6 provides a backup power supply, can meet the requirement that the terminal works for more than 10 minutes at full load after an external power supply is disconnected, and can provide a power supply necessary for the module in a timekeeping and sleep state. The power module realizes the power conversion function and comprises input protection, power switching, voltage and current monitoring, lithium battery charging, LDO and DC/DC. Since the peak current demand of the wireless GSM antenna 7 is 2.5A in 577 μ S of the transmission cycle, the power supply voltage decreases as the current increases. The power conversion chip for supplying power to the GSM module must meet the requirement, the LDO is most suitable, the output power supply ripple is small, but the large-current LDO is expensive, and the DC-DC chip is selected for realization in consideration of high cost and power loss.

And a buffer sponge 61 is also arranged between the lithium battery 6 and the PCB 5.

The LED driving module of the indicator light 9 is designed by adopting a CAT4101 TV-T75 chip, and the chip is a constant current LED driver with a PWM dimming function and can support 1A load at most. The lamp quality is controlled by a PWM mode, for example, a PWM control signal circuit is realized by adopting an SN74LVC1G32DBV OR gate circuit, namely two GPIO signals of ARM generate an LED _ CNTL signal after being superposed by the OR gate circuit, and the LED brightness control can be realized by the high and low level change of the signal. Because the system integrates the GNSS module, the GNSS module outputs 1pps signals, and the ARM is set to light or extinguish the LED at the rising edge of 1pps, so that synchronous flashing operation of a plurality of beacon lights can be realized.
