2 Safety

This chapter concerns your own safety and the safety of the system operator.

▸

Please read this chapter carefully before you begin working with the gateway system.

2.1 Qualified personnel

The gateway system must only be commissioned and maintained by properly qualified

personnel.

A qualified person

• has sufficient skills in the field of the respective equipment based on their technical

training and experience and

• has been instructed by the manufacturer in system operation and all applicable safety

guidelines and

• is familiar with all relevant country-specific occupational safety regulations, work safety

regulations, guidelines, and generally accepted technical rules and standards

(e.g., DIN standards, VDE regulations, country-specific rules) to such an extent that

they are able to evaluate the safe condition of the power-driven machinery, and

• has access to and has read the operating instructions.

2.2 Applications of the system

The Telematic Data Collector (TDC) gateway system is a system used to receive and

transmit telemetry data on a cloud server. It is, for example, ideal for sensor-controlled

monitoring tasks, vehicle tracking, working hours management, and access control as

well as for remote measurement.

The gateway system uses one or more TDC devices to collect data. The TDC devices

feature all of the standard interfaces that are required to integrate sensors and other

devices.

The sensor data received is transmitted to the cloud via the mobile network through either

the SICK online portal or a customer server.

The SICK online portal is a platform that can be used to visualize sensor data on a web-

based user interface, allowing for convenient monitoring.

The TDC gateway system also supports the integration of recorded sensor data into all

leading business applications. Integration is an option when using either the SICK online

portal or a cloud-based customer server via an API included as part of the scope of

delivery or via the MQTT protocol in a defined topic structure.

2.3 Intended use

The gateway system may only be used by qualified personnel in the environment in which

it was mounted and initially commissioned by qualified personnel in accordance with

these operating instructions.

If used in any other way or if alterations are made to the gateway system – including

in the context of mounting and installation – this will render void any warranty claims

directed to SICK AG.

3.2 System components

3.2.1 TDC devices – collecting and transmitting sensor data

The gateway system uses TDC devices to receive and transmit sensor data.

• As a receiver, the TDC device collects data from connected sensors and devices.

• As a sender, the TDC device transmits the sensor data received to the cloud via the

mobile network.

3.2.1.1 The TDC device as a receiver

A TDC device will generally receive sensor data from a vehicle or a machine. For this to

happen, the sensors are connected to the TDC device via appropriate interfaces.

The TDC device also has built-in sensors that are used to detect the movement of the

vehicle. This movement data can be output along with GPS data (this only applies to TDC

devices of the B series). A GPS antenna is included in the scope of delivery for these

devices.

Fig. 6: The TDC device as a sensor data receiver

Which sensors and devices can be integrated?

The TDC device features all of the standard interfaces that are required to integrate

sensors and other devices. Digital, analog, and CAN bus-based signals can be processed.

The interfaces are configured via the TDC Configurator configuration software included in

the scope of delivery.

TRANSLATION OF THE ORIGINAL INSTRUCTIONS | Telematic Data Collector

• SICK sensors of the TiM series detect the presence of an object within a specified area

(detection). They are ideally suited for monitoring the area around a vehicle, for

instance. If an object is detected in the monitored area, the result is output via the

digital output.

• Capacitive level sensors (such as those from the company Omnicomm) are used for

the level measurement of fuels and oils. When using a capacitive measuring method,

an insulated measurement electrode forms an electric capacitor with the medium

surrounding it. As the level and in turn the capacitance decreases, the latter is analyzed

by electronics and communicated by an electrical signal.

• Capacitive proximity sensors, such as SICK sensors of the CM series, can detect all

kinds of materials beyond a surface. This allows a minimum level to be detected, for

example.

• A TDC device can also process signals from other devices or motors. Vehicle activities

can be traced upon connection to the ignition system.

3.2.1.2 The TDC device as a sender

When using the SICK online platform, the TDC device transmits the sensor data received

to the SICK cloud server in real time. This happens automatically via the mobile network

using the SIM card inserted into the TDC device.

If a cloud-based customer server is used instead of the SICK online portal, it is not

possible to transmit the sensor data directly. However, there is the option to access the

data on the customer server using the MQTT interface of the device in question.

The TDC device alarm management system can be configured and used to trigger a real-

time alarm in the form of SMS messages via input signals.

Permanent data transmission in online mode

The TDC device is connected to a voltage supply and permanently supplied with voltage.

It is also always connected to the mobile network via the SIM card. The GPRS access data

for the SICK online portal is shared with the device through the TDC Configurator

configuration software.

This means that the TDC device is always online, regardless of whether the vehicle or

machine into which the TDC is installed has been started up or not. Sensor data is

therefore always transmitted in real time – even when the motor is not running. Given an

appropriate connection to the TDC device, starting up a motor or machine would therefore

constitute a signal in itself, which could then be transmitted and analyzed.

Data storage in offline mode

If there is no mobile signal, the data received from the connected sensors is stored on the

internal device memory. No matter how many sensors are connected, sensor data can be

stored for up to one month.

If the device is not connected to a voltage supply, it will not be possible to save sensor data.

The TDC device will be back online as soon as a connection to the mobile network is

reestablished, and at this point the sensor data that has been saved will be transmitted

automatically to the SICK online portal. When using an internal customer server, it will be

possible to access data again once the connection has been restored.

Fig. 9: Data storage on the TDC device in offline mode

If the connection to the mobile network is interrupted for longer than one month, the data

stored on the internal device memory will be overwritten in line with the FIFO (first in, first

out) principle. What this means is that the data that was stored first will be the first to be

overwritten.

This principle ensures that the data from the last four weeks is always available – even

when the connection to the mobile network is interrupted for a prolonged period of time.

Device logging

TDC device activity, such as when a voltage supply is connected or the mobile network is

accessed, is reported to the SICK online portal.

Using the notification management system, the SICK online portal can issue a message

in the event of a mains voltage failure or a failure of the mobile network (for further

information on this, please also refer to Chapter 3.2.2.3 Visualization and monitoring).
