Embodiment Construction

[0018] see figure 1 , is a schematic diagram of the vehicle-mounted machine. The vehicle-mounted machine includes a driving data acquisition box 11, which is connected with several sensors for collecting the driving data of the train, such as vehicle speed, mileage mark, etc.; the data conversion platform 12 is connected to the data acquisition box. The data collected by the data acquisition box 11 must be strictly isolated, so the effect of the data conversion platform 12 is to isolate the driving data acquisition box 11 and other equipment. The data conversion platform 12 includes a microprocessor and a storage unit for storing driving data. The device is used to control the work of the data conversion platform 12; the encoding unit 13 is connected to the data conversion platform 12, and the driving data is carried out to POCSAG encoding; Modulate, power amplify and receive the radio frequency signal of the alarm data of the ground terminal equipment to demodulate; the alar...

Abstract

This invention discloses a portable receiver when a train approaches to an early warning announce system including: an antenna for receiving RF signals carrying the train data, an emitting RF signals with warning codes, a super-heterodyne receive circuit connected with the antenna for demodulating the received RF signals to digital codes, a decoder connected with the said super-heterodyne circuit for decoding the digital codes to restore them into the train data signals before emitting, a microprocessor connected with the decoder for controlling the received digital signals and displaying them after check and sending out the warning signals and receiving operators instructions to control the sent warning codes, a transmitting unit connecting the microprocessor and the antenna for receiving instructions of the microprocessor and modulating the warning codes to send them out via the antenna.

Description

technical field [0001] The invention relates to an electronic communication product combining wireless communication technology and applied electronic technology, in particular to a portable receiver for early warning and forecasting of train approaching. Background technique [0002] In the railway system, when the staff on the railway line repairs and maintains the railway facilities, the train must run normally, which forms the contradiction and conflict between the maintenance of the railway facilities and the running of the train. If the safety guarantee is not effective, vicious safety accidents such as car crashes and casualties may occur. In the past, on-site operations and schedules mainly relied on train diagrams. However, when random emergencies occur, the train diagram must be changed temporarily. At this time, the lives of staff on the railway line will be threatened. In addition, when the railway staff suddenly finds that there is a serious situation endangeri...
