“…Figure 5 shows the configuration that is made in the GPRS of an alarm system; in this you must configure the APN provided by the communications company with their respective users and passwords, the receiver's IP, the receiver's port, the subscriber's number, telephone and life pulse; these last two items are provided by the central and are used in case the GSM network has failures, [52].…”

This article, in the context of documentary research carried out and interpreted for that was taken as baseline in investigations on electronic security and their themes for the ORCA group, it´s describe the state of the art of electronic surveillance focused in communications for monitoring stations. It’s set up chronologically in the last decade, in Latin America, and Colombia particularly. The subject has been categorized and subcategorized in such a way that keys are established sources extraction: university digital repositories, online academic magazines and corporate web page. As a product produced by the review, a particular communication model is presented for a case of a monitoring center and a equipment for tracking people.

“…With regards to safety, the integrated management of the critical factors in the process ensures an optimum reliability level in the industrial plants [ 5 , 6 ]. Factors such as the control of the process variables, procedures, and steps followed in the transitional stages are intended to keep the plants within the operating established limits [ 7 , 8 ]. On the starting or shutdown procedures, the quantity of signals increases, so the plant’s safety needs to involve the integrated management of those factors when analyzing the causes of the accidents.…”

In automated plants, particularly in the petrochemical, energy, and chemical industries, the combined management of all of the incidents that can produce a catastrophic accident is required. In order to do this, an alarm management methodology can be formulated as a discrete event sequence recognition problem, in which time patterns are used to identify the safe condition of the process, especially in the start-up and shutdown stages. In this paper, a new layer of protection (a Super-Alarm), based on the diagnostic stage to industrial processes is presented. The alarms and actions of the standard operating procedures are considered to be discrete events involved in sequences; the diagnostic stage corresponds to the recognition of the situation when these sequences occur. This provides operators with pertinent information about the normal or abnormal situations induced by the flow of the alarms. Chronicles Based Alarm Management (CBAM) is the methodology used in this document to build the chronicles that will permit us to generate the Super-Alarms; in addition, a case study of the petrochemical sector using CBAM is presented in order to build one chronicle that represents the scenario of an abnormal start-up of an oil transport system. Finally, the scenario’s validation for this case is performed, showing the way in which, a Super-Alarm is generated.

“…The use of digital data-based technologies in these systems suggests an increase in the amount of data that must be monitored and processed, including better communication ability among process agents [1]. Factors such as the control of process variables, procedures, and steps followed in transitional stages seek to keep the plants within the operating established "limits" [7] With regard to start up or shutdown procedures, the number of signals increases, the plant safety must have a comprehensive management of factors to analyze accident causes. In other words, these factors must be managed in a comprehensive, rather than separate manner, because if any of them is left outside, unattended or they decrease, this will be a safety threat [8]- [9].…”

When an industrial process changes its status, for example, start-up or shutdown, the alarm flood spreads, cuasing severe situations that prevent the operator's correct reaction.…”

An alarm management methodology can be proposed as a discrete event sequence recognition problem where time patterns are used to identify the process safe condition, especially in the start-up and shutdown stages. Industrial plants, particularly in the petrochemical, energy, and chemical sectors, require a combined approach of all the events that can result in a catastrophic accident. This document introduces a new layer of protection (super-alarm) for industrial processes based on a diagnostic stage. Alarms and actions of the standard operating procedure are considered discrete events involved in sequences, where the diagnostic stage corresponds to the recognition of a special situation when these sequences occur. This is meant to provide operators with pertinent information regarding the normal or abnormal situations induced by the flow of alarms. Chronicles Based Alarm Management (CBAM) is the methodology used to build the chronicles that will permit to generate the super-alarms furthermore, a case study of the petrochemical sector using CBAM is presented to build the chronicles of the normal startup, abnormal start-up, and normal shutdown scenarios. Finally, the scenario validation is performed for an abnormal start-up, showing how a super-alarm is generated.
