''''' | '''''Fuel level sensor (FLS)''' -'' device which is used for measuring fuel level. | ||
''''' | '''''Serial number''' -'' code consisting of letters and numbers assigned to a device (sensor). | ||
'''''CNT''''' | '''''CNT''' -'' an oscillatory circuit, thanks to which the basic level of filling of the sensor measuring tubes with fuel is calculated. This level is converted to a final value determined by the data interface. | ||
'''''Протокол передачи данных''''' - набор определённых правил или соглашений интерфейса логического уровня, который определяет обмен данными между различными программами или устройствами. Для ТД-150 основным протоколом передачи является '''LLS по интерфейсу RS-485''' и по интерфейсу '''Bluetooth''' для передачи пакетов данных используется протокол '''Escort BLE'''. | '''''Протокол передачи данных''''' - набор определённых правил или соглашений интерфейса логического уровня, который определяет обмен данными между различными программами или устройствами.

''' | '''Sensor's name''' - sensor's designation among BLE devices consisting from two letter from the sensor's model name and six last digits from the serial number; E.g. TD_100100; | ||
'''MAC- | '''MAC-address''' - unique identifier assigned to every active device. Used to recognize devices in the network. | ||
''' | '''Data packet''' - is a set of parameters transmitted by a device equipped with a Bluetooth transmitter, the structure of which is determined by the data transfer protocol. | ||
''' | '''Advertising mode''' - is a data transfer mode in which the device “distributes” data packets at a certain frequency, regardless of the presence of a device receiving the data. | ||
''' | '''Connection mode''' - is a data transfer mode in which the transmitter waits for a connection to the receiving device in order to begin transmitting data packets. | ||
'''[[BA-BLE|База BA-BLE]]''' - | '''[[BA-BLE|База BA-BLE]]''' - is a device that relays data transfer and converts it from a Bluetooth packet into a data packet transmitted via the RS-485 interface in accordance with the LLS protocol. | ||
''''' | '''''Data transfer mode''''' - this is a type of boundary between two objects or nodes, which are regulated by a special accepted standard and implemented using established methods, tools and rules. TD-150 has the following operating modes: | ||
* '''RS-485 ( | * '''RS-485 (Passive and Active)''' | ||
* ''' | * '''Analog''' | ||
* ''' | * '''Frequency''' | ||
''''' | '''''Interface''''' - a physical connection method and/or a set of software tools that allows data to be transferred between two or more devices. | ||
'''''RS-485''''' - | '''''RS-485''''' - digital data transmission mode. The sensor waits for a corresponding request from the receiving device. Works using the LLS protocol. Based on CNT, a value is generated in conventional units of the selected range (1-1023 units or 1-4095 units) | ||
''' | '''''Converter''''' - digital converter RS-485 to USB ([https://www.fmeter.ru/download/_ftp/escort_c-200m/%D0%9F%D0%B0%D1%81%D0%BF%D0%BE%D1%80%D1%82%20%D0%A1-200%D0%9C.pdf?v=200320145441 С200М] или [https://www.fmeter.ru/download/_ftp/escort_c-200m/%D0%9F%D0%B0%D1%81%D0%BF%D0%BE%D1%80%D1%82%20%D0%A1-200M2.pdf?v=150323104901 С200М2]) for configuring wired sensors. | ||
''''' | '''''Active (periodic) RS-485''''' - operating mode in which the sensor, without waiting for a request from the receiver, itself transmits packets with command data within 2 seconds. | ||
''''' | '''''Analog''''' - mode in which a corresponding voltage is generated based on the CNT in the approximate range of 0.2-9V. | ||
''''' | '''''Frequency''''' - mode in which the corresponding frequency in Hz is generated based on the CNT (301-1323 Hz with a value range of 1-1023; 301-4395 Hz with a value range of 1-4095). | ||
''''' | '''''Navigation terminal''''' - the main element of the system for monitoring the operation of transportation carried out by means of satellite communication. Without it, it is impossible to control transportation, to determine the coordinates of the vehicle location. It collects information from sensors and on-board system of the vehicle, and then transmits it to the device/server, which belong to the controlling specialist. | ||
