The basis of the Houston PeopleMover is the short stator, low speed, track mounted Linear Induction Motor (LIM), which propels up to six three-car urethanewheeled trains around a 2.38 km (1.49 mi) steel track with nine stations. Approximately 900 motors, controlled by hardware or microprocessor-based logic cards, are used in the system. Train collision protection is provided by a safety block system, which prevents a following train from entering an already occupied block. Each block is controlled by a pair of microcomputers, via a fully redundant set of motor inhibits and track-mounted caliper safety brakes. System supervision is provided by a programmable controller located in the central equipment area. This controller monitors system status, operates the central display board, and relays supervisory commands from central to the station microcomputers. A minicomputer monitors the programmable controller's input data to detect anomalous conditions and to create status reports and system logs. This system has been operating in Houston since July, 1981 with an availability greater than the contract-specified level of 99.6 percent.","PeriodicalId":230854,"journal":{"name":"32nd IEEE Vehicular Technology Conference","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1982-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116192471","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This feature was the result of a need to gather basic data on performance of the mobile telephone equipment and, in particular, on certain interactions of the user with the system. For this purpose, the mobile monitors many of its own actions and telemeters information to the Mobile Telephone Switching Office (MTSO). When a telemetry equipped mobile is enabled, it can make autonomous requests for the system's retrieval of telemetry information at periodic intervals determined by the system. Upon receiving the request, the MTSO commands the mobile unit to transmit the telemetry information. The actual telemetry data, along with any of the events associated with the request and retrieval process, is recorded by the Data Retrieval System (DRS). The DRS is a mini-computer based system connected to the MTSO for collecting and recording events occurring within the cellular system's No. 1 ESS switch. This paper addresses the specifics of the telemetry function, as implemented in the mobile unit and in the system, as well as the types of data that can be obtained or derived from this operating feature.","PeriodicalId":230854,"journal":{"name":"32nd IEEE Vehicular Technology Conference","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1982-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121359368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An alternative is to record the channel distortions (i.e. amplitude and phase variations) by probing the real channel and to use these stored signals to control the simulator in the lab. This stored channel method (SCM) has been applied to the following mobile radio channels • satellite to ship • SAR emergency buoy to satellite • base station to land mobile for low data rates A collection of tapes has been obtained for these channels under various conditions. They were used to compare several data transmission schemes at different data rates and various S/N-ratios, but with the same replayed fading fluctuations. The SCM was used to evaluate low rate data transmissions (< 10 Kbit/sec) with various modulation schemes such as CBPSK, digital FM, and DPSK/FM. Bit error rate results are presented. The experience with the SCM, its advantages and limitations are being discussed.","PeriodicalId":230854,"journal":{"name":"32nd IEEE Vehicular Technology Conference","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1982-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125976956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
