Data Center Monitoring

A Data Center is an installation of one or several rooms full of computers and electronic equipment which function as the server of company or an organization, whether it is public or private. These facilities, as well as their features and size, can vary. They can be from large buildings dedicated entirely to this function, to small rooms within the organization’s facilities. However, all of them have in common the need for constant monitoring, in real time and at different levels, to ensure the proper functioning of the equipment inside and that the conditions of the rooms are the most suitable for the maintenance of the devices.

In an example of a typical installation we find a building with four Data Center rooms with some variables we want to monitor. The data of these variables is sent by sensors and connectivity devices in the room controlling the temperature and humidity of the equipment in the room. Our solution is organized in four rooms, each one with a modbus temperature and humidity sensor and a connectivity module with up to 16 digital inputs and modbus output to which the sensors and the equipment are connected: an industrial cold unit, a network analyzer, UPS, sensors or any other device with digital output.

In terms of connectivity, since the rooms have a permanent internet connection, internet connectivity via Ethernet is established as the main means of communication. However, for the solution to continue working in the event of a network crash, it is necessary that the connectivity device can also access the network using LTE/4G technology.

Given these interface needs and with the requirement of significant processing capacity, the solution is designed around an MTX-Router-Titan II, an industrial router with high processing performance, RS485 Modbus connectivity and output via Ethernet or LTE/4G with different protocols.

The MTX-Router-Titan II performs a continuous polling of all Modbus RTU sensors connected to the RS485 bus to manage Data Center rooms. Each time a change in the registration of any sensor is detected, the MTX-Router-Titan II sends an alarm message to an SNMP Platform informing of such change or in case of reading failures (for example, power failure of the sensors) At the same time, the modbus registers of the sensors must also be read at any time from the SNMP Platform to check, in real time, the status of any of the devices connected to the solution.

On the other hand, always in parallel to the previous SNMP functionality, the MTX-Router-Titan II maps the modbus registers read from the sensors in its own internal memory to be able to act as a Modbus TCP slave and allow a reading platform to access via modbus to read the records stored directly from the internal memory of the equipment.

Finally, the MTX-Router-Titan II sends all the information, both modbus readings and the information itself, through MQTT to the Cervello Device Manager, which can act with both the Device Manager function for the management, control and monitoring of the devices, as well as with the Data Center Monitoring Platform function, allowing to visually display all the information of each of the sensors and records obtained in each of the CPD rooms on a personalized dashboard.

Thanks to this solution, remote monitoring of a Data Center center can be carried out, regardless of its size and configuration, in a simple, practical and efficient way, improving the efficiency of the maintenance of the facilities and increasing safety.

Data Center Monitoring

A Data Center is an installation consisting of one or several rooms dedicated to maintaining the best computer and electronic equipment that serve an organization, whether public or private. These facilities, as well as their characteristics and size, can be of a different nature, from large buildings dedicated entirely to this function, to small rooms within the organization’s facilities. However, all have in common the need for constant monitoring, in real time and at different levels to ensure the proper functioning of the equipment in them and that the conditions of the rooms are the most suitable for the maintenance of the devices.

In what could be a typical installation we find a building with four CPD rooms in which it is desired to keep monitored certain variables sent by the equipment of the room, in addition to maintaining a general control of the temperature and humidity of each of them. The solution is therefore organized in four rooms, with each one having a Modbus Temperature and Humidity Sensor and a module with up to 16 digital inputs and Modbus output to which different sensors or devices are connected to which its status is to be controlled. : Industrial Cold Unit, Network Analyzer, UPS, Current Sensors or any other device with digital output.

In terms of connectivity, since the rooms have a permanent internet connection, internet connectivity via ethernet is established as the main means of communication. However, for the solution to continue working in the event of a network crash, it is necessary that the connectivity device can also access the network using LTE / 4G technology.

Given these interface needs and with the requirement of significant processing capacity, the solution is designed around an MTX-Router-Titan II, an industrial router with high processing performance, RS485 Modbus connectivity and output via Ethernet or LTE / 4G with different protocols.

Finally, the MTX-Router-Titan II sends all the information, both Modbus readings and the information itself, through MQTT to Cervello Device Manager, which can act with both Device Manager function for the management, control and monitoring of the devices, as with the CPD Monitoring Platform function, allowing to visually display all the information of each of the sensors and records obtained in each of the CPD rooms on a personalized dashboard.

Thanks to this solution, remote monitoring of a CPD center can be carried out, whatever its size and configuration, in a simple, practical and effective way, improving the efficiency of the maintenance of the facilities and increasing security.

Industrial Cooling Unit Monitoring

In an increasingly global industrial sector in which companies aspire to sell their products worldwide, a remote monitoring, support and technical assistance system is essential to alleviate the costs of breakdowns and guarantees having thousands of kilometers of distance between the main headquarters and the installed equipment. A clear example of this: the companies dedicated to Industrial Cold, whose refrigeration units tend to be installed in any industry in the world, making prevention and remote monitoring the key to saving costs.

In these cases, the industrial refrigeration units are connected to a PLC that collects all the parameters sent by the equipment, stores them and sends them periodically thanks to the connectivity of an MTX device. The parameters sent collect information on consumption, outdoor temperature and some internal details regarding the status of the unit, such as an error log, the usage of certain components or the date of future revisions.

This PLC normally has an RS485 output, so the device necessary to achieve the solution must be economical, with RS485 and 4G / 3G / 2G connectivity (in order to cover all types of coverage regardless of the final destination). Due to these requirements, the solution is designed with an MTX-Java-T, a basic modem with an adjusted price, 4G / 3G / 2G connectivity and an RS485 input.

The data received by the MTX-Java-T is sent by MQTTs to the IoT Cervello platform, which transforms the information, stores it and allows it to be displayed graphically through different tables or graphics in the visual dashboard of the platform.

In addition to the data collected and sent periodically, the MTX-Java-T, thanks to its MTX-Tunnel firmware, allows the execution of commands that can directly and in real time request a specific data from the PLC. This can be done both from the Cervello IoT platform itself, and by simple SMS from an authorized telephone number. To add more intelligence, thanks to the MTX-Tunnel, it can also be managed that if a certain value of a selected variable leaves an established range, an alarm is sent directly via SMS.

Thanks to all this information, control and alarms carried out remotely, industrial refrigeration companies can reduce their warranty repair costs thanks to the forecast or even access to the error log of all their equipment installed around the world.

Conveyor Belt Monitoring

In a smart environment of management, control and industrial automation, one of the key elements to anticipate failures and increase productivity is to be able to monitor the status and use of conveyor belts of any kind of sector, whether it is for logistics or manufacturing. Thanks to the data obtained, the behavior of the belts can be studied (dilatation, deterioration, irregular advance…) thus creating patterns that allow to detect failures in the process. This way, it is possible to optimize the maintenance of the conveyor belts, increasing productivity and reducing the problems arising from the wear and tear of the machines.

Device: MTX-IoT-S, 4G IoT programable modem with 8x digital I/O and 2x ADC
Platform: Cervello IoT Platfotm

To obtain data, two inductive sensors detect metallic objects and calculate the distance between them based on the speed and frequency of detection. The first one is placed so that it can detect the movement of the conveyor belt itself. The second one is placed in the rotor. Thanks to these two independent measurements it is possible to detect if both elements are synchronized or if there is a speed difference between them, which could indicate a malfunction of the belt or a excessive weight supported (similar measures, but below the usual average).

The selected connectivity equipment should have enough capacity for three independent digital inputs and processing ability to capture the data, store it and analyze it thanks to an algorithm that allows to detect anomalies directly, allowing to send an alarm if something breaks before even sending the data to the IoT platform (Cervello). Due to these requirements the solution is designed with an MTX-IoT-S, an IoT modem with up to 8 digital inputs/outputs. The MTX-IoT-S, in addition, sends the data already processed in pre-recorded timestamps to an IoT platform (Cervello), which adds another complex layer of processing that allows analyzing the patterns in the behavior of the conveyor belts to foresee their deterioration.

The solution also includes a temperature sensor located next to the conveyor belt motor to monitor the operating temperature and detect overheating or abnormal temperatures. This information is also processed to send an alarm if the temperature is outside the range,and it’s also stored and analyzed in the IoT platform (Cervello).
