Below is a description of the "Sensors" tab, detailed examples of work are published here.

 

The "Sensors" tab of the object's card is intended for managing the composition and properties of the sensors used on the object.

At the top of the "Sensors" tab there is a control panel for the composition of controlled sensors, through which you canadd new,edit an existing one orremove the sensor.
 

It is also possible to export the created sensors or import them using the Import/Export button.

When exporting sensors, you can select a list of sensors and the need to upload their calibration tables and event templates to a *.csv file.

When importing, you can also make a similar selection.

The created sensors are shown in a table with the following columns:

№  - serial number of the sensor;

name, type, input number and input type  - fields of the same name specified in the sensor properties;

display  - flag for displaying the sensor in the tooltip of the monitoring panel;

alias  - variable to be set using the current sensor in the formulas of virtual sensors;

 sensor activity  - activates/deactivates the sensor. In the off state, the sensor does not participate in event detection and other calculations for the object.

Button "Add" is designed to add a new sensor to the object.

The following fields are available in the add sensor dialog:

Type  – selection of sensor connection type (simple/virtual). The simple type is used when entering physical sensors that are displayed in the dashboard as unregistered sensors or in the navigation report as non-calibrated.

The virtual sensor connection type allows you to create a sensor that uses other sensors. When selected, the "Function" field opens.

Alias  ​​– set variable for special formulas of the virtual sensor, using the current sensor;

Sensor type  - determines the type of sensor usage and is selected from the list of available, divided into groups. The sensor type must match the characteristics of the equipment installed on the site, otherwise the calculations may be incorrect.

Function  - the field becomes available when you select the type of sensor connection "Virtual" and allows you to select the aggregating function "sum", "average" or "expression".

The aggregating functions "sum" and "average" allow you to add physical sensors to the virtual sensor, which will be calculated as the sum of the sensors or their average value.

The aggregating function "expression" allows you to use a special formula in the field of the same name.

Formula  - the field becomes available when you select the sensor connection type "Virtual" and the aggregating function "expression". The reference book of functions and parameters of the virtual sensor with examples is available by clicking the buttonor by link

Calibration type  – enables/disables sensor calibration. The list of available calibration types depends on the input type and sensor type.

By default  - tare is not used;

On/Off  - discrete sensor, below in the Form  you can specify the text that will be displayed instead of On. or Off. ;

Table  - the output value is calculated in accordance with the calibration table, while the input parameters less than the first and greater than or equal to the last line are considered invalid and ignored. Thus, it is possible to cut off bursts / drops in the fuel level more / less than the maximum allowable;

Accumulator  - converts the input parameters into an accumulated value. For sensors of this type, the calculation table is applied to the difference between two adjacent messages. Used for flow meters and signal pickup devices. Also, for this type of calibration, you can specify the maximum value of the parameter in the Max. value . In the case when the parameter value reaches the maximum and jumps, the system will correctly calculate the "zeroing" of the sensor;

The difference from before  - also converts the input parameters to an accumulated value. Unlike the accumulator, it counts the input parameters since the previous measurement (message). For sensors of this type, the calculation table is applied to the difference between two adjacent messages. It is used for instantaneous flow sensors when the device transmits not the accumulated value of pulses, but the number of pulses between messages.

Invert  - enables/disables the inversion of the discrete state of the sensor.

Display in tooltip  - enables/disables the display of the sensor in the object's tooltip (a tooltip that the user opens by clicking on the element) of the monitoring window.

Enable median filtering  - allows you to apply a smoothing algorithm to the sensor readings. In the field, you must specify the degree of such smoothing from 0 to 255. The degree of filtering can be applied to the following types of sensors: on-board voltage, engine speed, engine temperature, trailer temperature, fuel, fuel level, fuel level in the tank, arbitrary.

Display last valid value  - enables/disables fixing the last valid value received from the sensor.

Color on chart  - allows you to select the color for displaying the sensor on charts.

Display track without ignition on  - the option is available for the "ignition" sensor type and affects the visibility of object movements without the ignition on on the map when generating the "Track" report. The feature works for both web and mobile versions.

In the monitoring system, the presence of ignition is an additional confirmation of the movement of the object. If it is necessary to display all movements of an object on the map when generating the "Track" report, then it is necessary to enable the corresponding option in the sensor settings. When this option is enabled, in addition to the main track, the map will also display the track of the object without the ignition on. The track will be painted in a translucent color, and tooltips when you hover over a track point will contain a note that the object moved without ignition on this section.

Display on the graph as a fuel level sensor "- the option is available for the "fuel consumption" sensor type and affects the display of the fuel consumption sensor on the graph of the "Track" report. When the option is enabled, the fuel consumption graph is displayed as a level and allows you to visually compare the readings of the fuel consumption and fuel level sensors. The line of the graph goes down with the increase in consumption, while it rises when the "Refill" event is detected. When the option is enabled, the graph of fuel consumption readings starts from the graph readings of a simple or virtual fuel level sensor. If the object has several fuel level sensors installed, but there is no virtual one, the fuel consumption graph starts from the fuel level graph that has a higher value at the beginning of the period requested in the report. If the object does not have a fuel level sensor, then when the option is enabled, the graph of the fuel consumption sensor is inverted. 

Calibration table  - the tab is available when selecting the types of calibration table, accumulator and difference from previous. and is designed to convert data that comes from a specific input into sensor values. For example, an abstract input value of 42 can be converted to 15 liters of fuel at the output.

The tab "Calibration table" is divided into two parts: on the left, the input value that comes from the equipment and the output value that should be used in reports are indicated. The graph of the calculation result is displayed on the right.

At the top of the tab there is a taring control panel, through which you canadd a new line, or  delete the existing one and also importtable via the clipboard, after copying it from another sensor by clicking the buttonor from an Excel spreadsheet.

The Save button replaces table rows with clipboard values.

Buttonallows you to go to the historical list of calibration tables. More details about the functionality can be found in the article .
 

Sensors  - the tab becomes available when you select the virtual type of sensor connection with the aggregating function "sum" or "average".

At the top of the “sensors” tab there is a control panel for aggregated sensors, through which you canadd or  remove sensors.

Active sensors added in this way are excluded from displaying in the charts and the object tooltip separately. The virtual sensor will be displayed.
 

Add. settings  - the tab becomes available when you select the type of sensor "Arbitrary" and allows you to fine-tune the sensor depending on the scope of its application.

Type  - allows you to select sensor presets from the "Discrete" and "Analog/Pulse" profiles.

A discrete profile activates the capture of an operation event and the display of the sensor in the payload graph with the rendering type Area.

The analog/pulse profile activates the display of the sensor in the payload graph with the Line drawing type.

Capture work events  - adds the "Operation Sensor_name" event template, the name of which can be changed in the "Operation event name" field.

Fix the number of triggers  - the option becomes available when the "Fix operation event" checkbox is enabled and adds the event template "Number of triggers Sensor_name", the name of which can be changed in the "Name of triggers events" field.

Sensor triggering by selected conditions can be tracked in a separate tab of the "Track" report.

Display on the map  - the option becomes available when the "Fix the number of triggers" checkbox is enabled and displays the sensor triggering on the map.

The sensor operation icon displayed in the “Track” report can be selected from the library.

The options Show on the object chart  and  Show on the payload chart  allow you to enable the display of sensor operation readings in the object and payload charts as a line or area by selecting the appropriate drawing type. The "Area" drawing type is used for discrete sensors, and "Line" for all others.
