Base station control processor for managing status/alarm message and system time received by GPS receiver

A global positioning system (GPS) receiver 2-1, 2-2 in a base station (BTS) 10 of a PCS (personal communication services) system receives current time and position information from a GPS satellite, and generates various clocks for the BTS subsystem. The GPS receiver also generates status/alarm management data and system time message data (time-of-day (TOD) data) which is sent to the GPS base station control processor 20 at regular intervals. The control processor extracts system time information from the system time message data and immediately broadcasts it to all the processors 22 in the base station. Periodically the status/alarm message data is checked for changes and any changes are reported to the base station controller. Thus the base station provides stable clocks and accurate system time for operation of the base station system, without the need for a time and frequency processor (TFP).

The method and device are intended for two embodiments of mains-synchronised integrated clock circuits (2, 2a), of which one (2) has an input (5) for pulses at mains frequency and an input (R) for resetting pulses, and the second has only one (S)-input. In the event of a mains failure, the clock circuits continue to emit 1 Hz pulses which control the synchronisation after mains voltage has returned. A short mains failure does not impair the synchronisation. The device contains logic circuits (1, 13, 14, 15 or 18) in addition to the clock circuits (2, 2a). The logic circuits (1, 14) consist of at least one D flipflop (5) and an AND gate (6). The clock circuit (2) with a resetting input (R) contains a logic circuit (1) having an input for 1 Hz pulses and a differentiating network (7). The clock circuit (2a) with only one synchronisation input (S) requires a downstream pulse shaper (13) for 1 Hz pulses, a changeover switch (18) switched by the logic circuit (14), and an oscillator (15).

Industrial controller with coordinated timing

A method for providing a standard coordinated time throughout spatially separated functional modules of an industrial controller employs a module operating as a time-master which transmits a coordinated time value to various dependent modules through communication modules. The particular time-master is determined by an arbitration process among potential masters which examines a time quality value, indicating the precision of the time-master's clock, and incorporated in the transmitted synchronization signal. Upon the loss of a master or the introduction of a new master, mastership is reallocated so that the master time value is provided from that module having the best time quality. Offset caused by "ripple through" of the time value through communication modules is minimized by summing to that time value as it traverses a communication module with a time quantity measuring the processing time of the communication module.

Method of scheduling spatially separated control events with an industrial controller

A coordinated system time is established for spatially separated components of an industrial control system using synchronizing messages transmitted over a communication link between those parts. Precisely coordinated actions may be obtained at separated components by the use of a time conditional command received by those components prior to a time of execution the command instructing the component to execute the command only when at execution time in the future has been reached. The coordinated system time may be used to time stamp received triggering events for use in coordinating subsequent actions based on those triggering events.

Protected clock synchronisation

FIELD: electrical engineering.SUBSTANCE: for single-stage transfer of a clock signal as per IEEE 1588 standard symmetrical and asymmetrical protection circuit. Clock signals of crucial or widely available devices in industrial automation systems connected to communication network are synchronised by means of synchronization message transfer by master clock generator, in particular one message of single-stage synchronisation as per IEEE 1588 standard with time stamp and receipt and evaluation of this message by slave clock generator. Before beginning of the planned time moment tsynchronising component or module of the master clock generator prepares or shapes synchronisation message that includes time stamp of the transfer and protects is before moment of transfer. Protection of synchronisation message is carries out by appropriate cryptographic means that allow at least identification of the time stamp in the slave clock generator, for example, by method of computation and sign assignment for check sum or hashing of the synchronisation message. Transfer of the protected synchronisation message is carried out at the planned moment of time.EFFECT: improved accuracy of clock synchronisation.8 cl, 4 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) 2 487 382 (13) C1 (51) МПК G04G 7/00 (2006.01) H04L 12/42 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (21)(22) Заявка: 2012101763/08, 13.05.2011 (24) Дата начала отсчета срока действия патента: 13.05.2011 (72) Автор(ы): КИРРМАНН Хуберт (CH), ТУРНЬЕ Жан-Шарль (FR) (73) Патентообладатель(и): АББ РИСЕРЧ ЛТД (CH) R U Приоритет(ы): (30) Конвенционный приоритет: 09.06.2010 EP 10165325.1 (45) Опубликовано: 10.07.2013 Бюл. № 19 2 4 8 7 3 8 2 (56) Список документов, цитированных в отчете о поиске: EP 2148473 A1, 27.01.2010.
