GEM INTRODUCTION

1.What is the GEM

GEM(Gosafe Event Management) is a type of scripting language, which allows users to perform specific tasks or a series of tasks through GEM script programming. GEM uses events to monitor device status or environmental changes and perform certain actions in response to those changes. GEM components mainly include Events, Parameters, States, Timers, Counters and Actions. 

GEM scripts, which can be used to write the complete business logic and processes of GEM tasks according to the syntax of GEM conventions. GEM scripts support 64-bit programmable flags, 32 programmable timers, 256 custom program labels, and 512 programmable events. Supports 255 user-defined code events and uploads to the specified server via COAP/UDP and/SMS.

2.How GEM Works?

When the Generator was Generated, GEM will send an event to the GEM message queue. The event message arrives, GEM retrieves the message sent by the first Generator from the message queue, and searches for the matching Generator from the event numbered 0 through the event list.

When a matching Generator is found, GEM tests the corresponding State. If the result of the test State is true, the specified force will be performed. After performing the specified force, the GEM continues to search through the event list for the remaining matching Generators and performs the above process until the end of the event list.

After finishing this, the GEM retrieves the message sent by the next Generator from the message queue and processes it again. Then repeats this process until the message queue is empty.
