® Symeo LPR -System ® LPR -2DB Product Documentation 1 General 1.1 Safety Instructions LPR®-2D systems are purely tracking and assistance systems. They therefore do not satisfy special requirements for personal safety, e.g. performance level c. Follow the safety instructions in the operating instructions for the device and the additional documentation! Keep these safety instructions and other documents together with the device. 1.
® Symeo LPR -System ® LPR -2DB Product Documentation 1.5 Power Supply A safety-inspected power cable that satisfies the regulations of the country of use is required for the device. Devices with metal housings must only be connected to a grounded, shock proof socket. The device must not be operated unless the nominal voltage of the device matches the local supply voltage. Check the supply voltage of the device in stationary devices.
® Symeo LPR -System ® LPR -2DB Product Documentation must be complied with. The warranty shall be voided if you cause defects to the device by installing or exchanging system extensions. 1.8 Additional Instructions Regarding Compact Type and Integral Type Stations The Compact type LPR station must not be opened except for installation. The Compact station contains no serviceable components. When opening, ensure that no fluid gets into the housing.

® Symeo LPR -System ® LPR -2DB Product Documentation 3 System Description SYMEO Industrial Local Positioning Radar (LPR) is a system for contactless, real-time determination of distances and positions. LPR B 2D is a distance measurement system which is particularly well suited for use in very harsh, industrial environments, in which other systems such as mechanical rotary encoders or lasers cannot function for long periods.
® Symeo LPR -System ® LPR -2DB Product Documentation *3 Temperature inside the housing can range from -40°C to 85°C. 3.2 Operating Mode There are different system topologies to determine a 2D position with a Symeo LPR® system. Which operating is best suited depends on the application and the environment. It depends on the number of mobile units you want to track and on the number of cells which are necessary to cover the environment.
® Symeo LPR -System ® LPR -2DB Product Documentation signal with precisely known delay and an individual frequency offset corresponding to the fixed mounted unit measurement ID. The mobile unit computes the round-trip time-of-flight and therefore the 1D distance to each transponder. Finally, the mobile unit calculates of all single 1D distances a 2D position.
® Symeo LPR -System ® LPR -2DB Product Documentation If desired the master transponder can store the coordinates of the cell (mode 2b). The master transponder then repeatedly broadcasts his coordinates and all base-stations in range receive the data. Alternatively the coordinates can be kept on the mobile unit permanently as in mode 1 (mode 2a).
® Symeo LPR -System ® LPR -2DB Product Documentation If desired the master transponder can store the coordinates of the cell (mode 3b). The master transponder then repeatedly broadcasts his coordinates and all base-stations in range receive the data. Alternatively the coordinates can be kept on the mobile unit permanently as in mode 1 (mode 3a).
® Symeo LPR -System ® LPR -2DB Product Documentation The model is set by Symeo by delivery. 3.3.1 Hover-Track The HoverTrack model is used for vehicles that can move in x- and y-direction but cannot turn over its center. A typical example is the trolley of a crane. The name based on a hovercraft which can move forward and backward as well as sideward. To make a 2D-positioning the mobile unit needs at least one antenna.
® Symeo LPR -System ® LPR -2DB Product Documentation The configuration files are: LPR-2DB Station (Mobile unit): basestation_config.txt LPR-2DB Integral Station (Fixed-mounted unit / transponder): stationXX0_config.txt stationXX1_config.txt stationXX2_config.txt stationXX3_config.txt stationXX4_config.txt stationXX5_config.txt (XX: Cell-ID) stationxxM_config.
® Symeo LPR -System ® LPR -2DB Product Documentation These 1D distances are forwarded to the software FusionEngine. The FusionEngine can either be on the ARM9 board of the mobile unit or on a separate PC of the customer. In the software FusionEngine all 1D distance measurement are merged to a 2D positioning.

To keep the protocol simple (i.e. easy to parse) the following aspects are considered: consistent data packet The protocol has a standard data packet with a fixed length. configuration The structure of the protocol can be configured by the user. It is possible to output only the required data.
® Symeo LPR -System ® LPR -2DB Product Documentation A protocol output is sent at regular intervals - independent of the availability of a valid position. The default output interval is 100 milliseconds. To set another output interval (e.g. 200 ms), insert the following parameter in the configuration file of the protocol: [OutputInterval_ms] 200 With the default configuration (OutputOnlyLockedTracks=1 in data field POSITION), only valid positions are sent (LOCKSTATE=2).
® Symeo LPR -System ® LPR -2DB Product Documentation 10.2 Binary format of the protocol For the binary format the entire data packet of the 2D protocol is transferred as binary data. This means that the binary format is more compact than the ASCII format, but is not humanreadable. 10.2.1 Data types The length of all data fields is a multiple of one byte. The data types are exclusively bit field or integer. Integers can be signed or unsigned.

In the worst case the whole data packet consists of exclusive symbols. In this case the length of the data packet is doubled.

It can be disabled via the following line in the configuration file: [SendPosition] 0 The protocol is configured per default, that only a reliable position is output (LOCKSTATE 2).

Up to five errors can be displayed simultaneously in one data packet. An error code is sent as long as an error exists.
® Symeo LPR -System ® LPR -2DB Product Documentation Name Length Type Description SAT-COUNT 1 signed int Number of satellites tracked The single allowed negative value is “-1”, it means “unknown”, e.g. in case of hardware failure. SAT-HDOP 2 signed int 10 * horizontal dilution of precision So the integer 123 would mean a 12.3 HDOP. A HDOP value of “-1” (given as “-10” in this format) means “unknown”, e.g. in case of hardware failure.
® Symeo LPR -System ® LPR -2DB Product Documentation 10.3 ASCII format of the Protocol For the ASCII format of the 2D protocol the entire data packet is transmitted as ASCII-code by letters, numbers and some special characters. This means the ASCII code is humanreadable. Due to the fewer encoding characters the data is transmitted not as compact as for the binary protocol, so the amount of data increases. 10.3.
