This standard applies to the scheme, carried out manually or by automated means, products of all industries and construction, and establishes a conditional graphical notation (SSD) devices robot. (Revised edition, Alt. № 2). 2. General notation telemetry devices are shown in Table. 1. Table 1: Name Designation 1. Remote control device. Note. Turning the conventional graphical notation is not allowed, or 2 device (appliance) remote control 3. To indicate the direction of transmission (reception), signal devices, remote control on the line put qualifying symbols transfer (receive) signal, presented in Table. 2. Table 2: Name Designation 1. To use the device remote control: a) transfer b) at a reception in) to receive and transmit simultaneously r) on the transmitter and receiver alternately 2. To use the device on the robot «n» channel 3. To use the device to relay telemetry Note. Qualifying symbol retransmission ? assign robot devices from which the relay, and placed it next to the ASB on the line (Revised edition, Alt. № 1, 2). 3a, 3b. (Deleted, Mod. № 2). 4. In constructing the robot SSD devices within the general notation in the bottom field is placed qualifying symbols of functions performed by this device are listed in the Table. 3. Table 3: Name Designation 1. Remote control: a) the transferor b) the receiving party 2. Teleregulirovanie: a) the transferor b) the receiving side 3. Telesignalization: a) the transferor b) the receiving side note to Secs. 1-3. In cases where the devices robot does not specify the transmitting (receiving) side, allowed the function "remote control", "teleregulirovanie" and "signaling" refers to paragraphs. 1a, 2a, 3b, respectively 4. Remote metering: a) the current values ??of the parameters which are displayed with the record b) the current display to record a) voltage indication with a record of) the power to display a record d) of the integral values ??Note. When telemetry to specify the receiving side is allowed affix a qualifying symbol «y». 5. Telekomandovanie 6. Teleautomatics 7. Transferring production of statistical information Note to paragraphs. 1-7. Used to indicate the capacity (number of managed objects) device remote control with a qualifying symbol of the function performed by a specific device, may be placed above numerals. 8. Calling a 9. (Deleted, Mod. № 3). 10. Selectable Notes: 1. To specify the functions of telemetry current, voltage, power and other electrical parameters in the devices robot is supposed to apply qualifying characters distinguishing mark of the measured value, for example: a) current measurement with the indication from the record b) measuring the voltage indication with a record of) power measurement with display with a record 2. To specify a particular device function remote control is supposed to apply lettering with the necessary explanations, for example, telemetry unit current settings with VTI indication on call. 5. To indicate the type of signal transmission (reception) within the common signs telemetry devices in the top box put the characters sort of qualifying current and voltage or pulse shape in accordance with GOST GOST 2,737 and 2,721. 4, 5. (Revised edition, Alt. № 2, 3). 5a. To indicate the type of information transmitted using qualifying symbols: (digital) and (analog), respectively, to pass from the input or output, next to the symbol graphic symbol. 5b. Examples of building conventional graphic symbols telemetry devices are shown in Table. 4. Table 4: Name Designation 1. Remote control device transmits alternating current of 10 executive sites 2. Teleregulirovaniya receiving device 2 objects 3. Signaling device transmitting at 15 sites 4. Signaling device on 20 objects 5. Signaling device on a call from 15 sites 6. Telemetry device current parameter values ??with indication of performing the transmission of binary Five digit codes-pulse method 10 objects 7. Telemetry device voltage indication transmitted output digital data 8. Telemetry device integral values ??5 objects 9. Telemetry device current settings which are displayed on-call two objects 10. Active power device telemetry transmitter Note to paragraphs. 6-10. In the notation of telemetry allowed to specify a unit of the measured value, the characteristics of the measured quantity (eg, type of current), device type, etc. In this case, the designation of the unit is placed to the left of the bottom margin, or within the bottom margin on the left of qualifying symbol measurement functions and characteristics the device type, etc., respectively, on the right, for example, telemetry transmitter power measurements with indication of three-phase two objects 11. Device telekomandovaniya 10 objects 12. Device teleautomatics 5 objects 13. The device transfer production of statistical information 3 objects 13a. Telecommand and telemetry device with display and recording transmitter, changing the sound frequency modulation and the host of n communication channels 13b. Device remote control transmitter at 10 sites, with indication of current telemetry receiver from 2 sites, signaling the receiver of 8 objects in n communication channels 13c. Device remote control transmitter at 7 facilities, telemetry receiver with recording from 20 sites, signaling the receiver of 15 objects 14. Adder 15. The device scaling 16. Summing amplifier 17. Note the primary converter. The letters X and Y are respectively the input and output parameters of 5a, 5b. (Established in addition, Mod. № 2). 6. Dimensions of basic notation telemetry devices are shown in Table. 5. Table 5: Name Designation 1. Remote control device 2. Telemetry apparatus Reference APPENDIX TERMS AND THEIR DEFINITIONS device (appliance) remote control - a device that performs an independent auxiliary function (conversion, amplification, summation, etc.) and represents a single structure. Calling the object - to send commands to a distance of a connected device robot controlled object to the communication channel. Transferring production of statistical information - transmission distance alphanumeric information. Remote control - transmission distance of signals that affect the executive bodies of the managed object. Teleregulirovanie - transmission distance of signals that affect regulatory authorities managed object. Telekomandovanie - to send signals to a distance of orders on duty personnel controlled object. Teleautomatics - automatic distance control systems, signaling devices, etc. - to send signals to a distance about the state of the controlled object. Remote metering current values ??of the parameters - measuring distance quantities that characterize the mode of the controlled object. Remote metering integrated parameters - measuring distance variables whose values ??are obtained by integrating over time. Remote Control, - convert and transfer of technical data associated with the system of rights to the technical installations, or vice versa, or between technical installations.
