Suntech ST4345GPS Enabled LTE CAT-M1 AVL Device

Introduction

This document describes features, protocols and detail operation of ST4345.

If there is another operation description document for special buyer to customize or model and the contents of the document is different with this, customizing document should be applied for special buyer.

Overview

Device consists of LTE-M1, GPS and event parts. The main purpose of device reports getting GPS position and other informs of vehicle to server periodically. Device can control or check connected lines and support additional functions.

Operation Mode

The device has 3 operation modes, driving, parking and emergency.
Driving : Driving status when ignition is on.
Parking : Parking status that starts if ignition is off during more than T1.
Emergency** : Once panic button is On or any other status as per designed.
The device sends emergency reports until A1 times or receiving server acknowledge.

Report

AVL reports GPS and some information at predefined interval, depending on the current modes. Also, AVL sends some alerts, for example, movement at the parking condition, changing of connected input line and so on.
Device distinguishes all reports with 6 types, Status report, emergency, event, alert, alive and command response.
Device can store reports when reporting route (For example, LTE-M1 condition) is not successful. Storage capacity is up to 2,000 status reports, 50 emergency reports, 50 alert reports (include event reports) and 1500 bytes as command response. In case of status reports, oldest report is erased and new report is buffered when the buffer is full and new status report enters (FIFO). When reporting condition is recovered, device starts sending all buffered reports. Also, this capacity can increase if it is needed.
Each type of reports has priority, and priority is as below.
Emergency ➔ Command Response ➔ Alert ➔ Status Report➔ Alive (Lowest)
Emergency is the first to be sent after recovering LTE-M1 condition.

Setting Parameter

Parameters of device can be changed by LTE-M1 or SMS, and some control can be realized also in the same way.
Detail protocols are described in Chapter 4.

Features

Key features are described here;

– Power Down
Device can process two steps of power-down, Sleep and Deep Sleep, for reducing power consumption when the vehicle is parked.

– LED Indicator
LED indicates LTE-M1 and GPS states. It’s helpful to check error cause.

– Events
Device has 2 output lines, 3 input lines and ignition line.

– Update Firmware by Over The Air (FOTA)
When Firmware of device has some error or has to be changed for a new service to be implemented, device can update internal ROM file by over the air (FOTA), remotely via LTE-M1. Customers do not need to visit every vehicle to download the new firmware. Method of FOTA describes at “SunTech_OTA_UA_Protocol” document in detail.

– Parking Lock
Device can check whether the vehicle moves off the preset parking boundary or starts driving without ignition on. In the case that it notes the unauthorized moving or driving, it sends emergency report immediately.

– Over speed
Device can check speed of vehicle and send alert of over-speed to server.

– GPS Antenna Checking
Device can alert when GPS antenna is disconnected. It’s applicable only for models that have external antenna.

– Main Power Checking
The device can recognize the main power and inform to server when main power line is disconnected or main power drops below preset value. It’s applicable only for battery model.

– Battery Error Alert
Device can alert about battery error related on charging. It’s applicable only for battery model.

Protocol Construction

All command and reports are string and follows below format.

** If report interval is set big number, network may disconnect LTE-M1 connection because LTE-M1 communication is not progressed for a long time. So, unit may not receive command by LTE-M1. T4 is for protecting against this disconnection by sending short data with short term.

** Alive report can be sent only when the device has no data to send during T4 interval.

** Function of M_SEMSOR can be used with the model that has motion sensor.

If shock or collision detection is enabled, device will report to server when gets any shock or collision.

** If this parameter has been customized, This table should be disregarded and you should follow customized

operation document.

_CONTYPE

1. KEEP_CON : The device keeps TCP connection always and can receives a command by LTE-M1.

2. KEEP_DISCON : The device connects TCP connection when the data is sent. After sending, the device disconnects LTE-M1 and TCP connection if it estimates there is no data for sending within 3minutes. In this case, it cannot receive a command by LTE-M1.

3. KEEP_NOP : The device doesn’t send any report after be installed. When the device enters emergency mode or receive ‘Start Report’ command by SMS or RS232, it starts report depending on report parameters. It may be used for saving LTE-M1 fee. Current version cannot support this
option.

Group Send
The device stores data if the vehicle is in no LTE-M1 area. And, the vehicle moves to LTE-M1 available area,
device starts sending stored data.
If group send option is enabled, the device makes 5 reports to one bundle and send these 5 reports at one
time.
Group send is useful to speed up sending.

M_Sensor

Collision: The device sending a event when ignition is ON and have a motion.
Shock: The device sending a event when ignition is OFF and have a motion.

Jamming detection procedure
JAM_CHK_DIST & JAM_CHK_TM are assist for jamming detection to avoid false detection.
At least, we recommend use JAM_CHK_DIST for safety.
If you use two assist functions, it can detect two case of jamming as follows.

Case of jamming LTE-M1 only.
Jamming detected -> JAM_CHK_DIST -> JAM_CHK_TM -> Triggered by JAM_DET mode.
Case of jamming LTE-M1 & GPS.
Jamming detected -> JAM_CHK_TM -> Triggered by JAM_DET mode.

JAM_CHK_DIST : if 0, skip this function.
JAM_CHK_TM : if 0, skip this function.

If disable all of assist functions, just triggered by HAM_DET mode after detected jamming.
In this case, it’s possible to false detection in weak LTE-M1 or strong radio area.

Command response doesn’t need ACK.

DEV_PORT| String| | Device’s port for receiving command from UDP server. It can be used only when UDP server is used.

If ‘0’ or empty, the device would use port 9000.

This command can be applied from software version 22.

ACK in case of UDP

UDP is protocol that doesn’t check whether the data is transmitted successfully. So, the device checks completion of sending with ACK depending on UDP_ACK type.

ACK is sent by server when the data is received.

If the ACK is not sent during more than 2 minutes after sending, the device recognizes the data was not reached to server and sends the data again

Examples of ACK report are as below.
String Format : “ ST4345ACK ;850000”
Zip Format : 0x15 0x85 0x00 0x00
It is recommended ACK_TYPE is set to ‘1’ to confirm all data can be transmitted safely.
