Wireless Sensor Network Overview DT Wireless sensor network is a high-speed, scalable sensor data collection and sensor network system. Each system consists of a wireless sensor interface node, a data collector gateway and a software platform based on the host computer. Two-way wireless communication between nodes and gateways enables sensor data collection and configuration from up to two kilometers away. The gateway can be locally connected to the host computer for real-time data collection and analysis. Some gateways also have analog output capabilities that can transmit sensor data directly to a stand-alone data acquisition device or directly interface with industrial control equipment such as PLCs. The selection of available nodes allows interfacing with many types of sensors, including accelerometers, strain gauges, pressure sensors, load cells, torque and vibration sensors, magnetometers, 4 to 20 mA sensors, thermocouples, RTD sensors, soil moisture and Humidity sensors, inclinometers and displacement sensors. Some nodes come with integrated sensing devices such as accelerometers. A single gateway can coordinate multiple nodes of any type, and multiple gateways can be managed from one computer using a host computer software platform. 2. Node Overview The TC-UNIT-1 is a small, wireless, low-cost, dual-channel analog input sensor node ready for OEM integration. Featuring one differential and one single-ended analog input channel and an internal temperature sensor, the TC-UNIT-1 is capable of collecting high-resolution, low-noise data at sampling rates up to 1 kHz. Other features of the TC-UNIT-1 include an adjustable PGA, digital low-pass filter, flash memory, automatic strain gauge calibration using on-board shunt resistors, and a pulse input channel for RPM measurements. This wireless sensor is ideal for connecting to a variety of sensor types, including strain gauges, pressure sensors, load cells, and displacement sensors. To acquire sensor data, TC-UNIT-1 is used together with the DT-UNIT-BASE gateway. 1 2.1 Interface and Indicators Figure 1 - - Interface and Indicators Indicator Device status indicator Behavior OFF Rapid green flashing on start-up 1 (slow) green pulse per second 1 green blink every 2 seconds Blue LED during sampling Red LED Node Status Node is OFF Node is booting up Node is idle and waiting for a command Node is sampling Node is resynchronizing Built-in test error Table 1 - Indicator Behaviors 2.2 Node Operational Modes Sensor nodes have three operational modes: active, sleep, and idle. When the node is sampling, it is in active mode. When sampling stops, the node is switched into idle mode, which is used for configuring node settings, and allows toggling between sampling and 2 sleeping modes. The node will automatically go into the ultra low-power sleep mode after a user-determined period of inactivity. Figure 2 - Node Operational Modes 3. Connect to the Base Station and the Nodes 3.1 Software Installation Before connecting any hardware, first install the host computer DT Wireless software on the host computer. To obtain the software installation package, please contact the relevant sales engineer or technical service engineer. Figure 3 - DT Wireless software installation package 3 3.2 Gateway Communications portland Drivers for the USB gateway are included with the DT Wireless software installation. After installing the software, as long as the gateway is plugged in, the USB gateway will be automatically detected 1. Power the gateway via USB connection. Verify that the gateway status light is on, indicating that the gateway is connected and powered on. 2. Open the DT Wireless software. 3. The gateway should automatically appear in the controller window with the communication port assigned. If the gateway is not discovered automatically, verify that the port on the host is active and then unplug and replug the USB connector. 3.3 Connect to Nodes Figure 4 - USB Gateway Communication In DT Wireless software, you can use several methods to establish communication with nodes: automatic node discovery on the same frequency, automatic node discovery on different frequencies, and manual node addition. 3.3.1 Automatic Node Discovery on Same Frequency If the base station and node are on the same operating frequency, the node will automatically appear below the base station list when the node is powered on. 4 Figure 5 - Node Discovered On Same Frequency 3.3.2 Automatic Node Discovery on Different Frequency If a red circle with a number appears next to a base station, the node may be operating on a separate radio frequency. Figure 6 - Node On Other Frequency Select a base station and then select the node tile on a different frequency. Tick the new node to be added and select "Apply" to move the node to frequency Figure 7 - Move Node 4. Wireless Sensor Configuration 4.1 Hardware Configuration Node settings are stored in non-volatile memory and can be configured using DT Wireless software. This chapter describes user-configurable settings. 5 Figure 8 - Hardware Configuration Menu l Temperature Sensor There are three sensor type options: thermocouple, RTD, and thermistor. Sensor type options vary depending on the sensor type selected. There is a drop-down menu for selecting the wire type for the RTD l l Input Range The input range is automatically determined based on the sensor type, unless the sensor type is uncompensated. Available ranges are ±1.35 V, ±1.25 V, ±625 mV, ±312.5 mV, ±156.25 mV, ±78.125 mV, ±39.0625 mV or ±19.5313 mV o -Uncompensated Input range is defined in mV for thermocouples and ohms for Uncompensated RTDs and thermistors. This field does not change based on the sensor type setting. l Low Pass Filter The adjustable digital decimation filter allows low-pass filtering between 2.6 Hz and 294 Hz. 4.2 Calibration Configuration The software automatically applies these coefficients when the node outputs data in the specified units: Celsius, Fahrenheit, or Kelvin. 6 Figure 8 - Wireless Sensor Calibration Menu 4.3 Sampling Configuration TC-UNIT-1 has two user-configurable sampling options, including lost beacon timeout and diagnostic information interval. It can be entered from the following menu: Configuration > Sampling menu Figure 10 - Sampling Configuration Menu 4.4 Power Automate The TC-UNIT-1 has multiple user-settable power options, including default operating mode in the wireless node, user inactivity timeout, check radio interval and transmit power. Configuration > Power Menu 7 11 - Node Configuration Power Menu l Default operating mode After powering on, the node will enter the default operating mode. In idle mode, if the node does not receive any commands within the selected time, it will automatically enter sleep mode. If active is selected in the default operating mode, the node will automatically re-enter the sampling mode last executed with all current settings. l User inactivity timeout Disable user inactivity timeout to avoid nodes automatically changing state. . l Check Radio Interval In sleep and sample modes, check how often the radio interval setting node checks the radio channel for the "set to idle" command. Reducing the check radio interval will shorten the time required to wake the node into idle mode, but at the expense of reduced battery life. Increasing the check radio interval can extend battery life, but at the cost of increasing the time required to wake the node into its idle mode. l Transmit Power Set the radio's output power to a value between 0dBm and +20dBm. Transmit power affects communication range and battery life. 8 5. Wireless Sensor Sampling Configuration 5.1 Start Collecting Data There are several ways to collect data from nodes, including from a single node, a network of nodes, or restarting the last used sampling mode. l Single node Device/Select the corresponding node ID > Sampling > Application to complete the data collection of a single node Figure 12 - Single Node Sampling l Network of the Node Device > Base Station > Sampling > Check the node to be sampled > Apply and start sampling.
