Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] Such as figure 1 As shown, the initialization of the master E1 interface 8, the slave E1 interface 7, and the time slot exchange unit 6 is completed by the CPU unit.

[0028] The asynchronous serial port unit 1 and the smart device perform asynchronous serial port communication, the serial / parallel conversion unit 2 collects the data on the asynchronous serial port unit 1, completes the serial-to-parallel conversion, the parallel data is buffered in the latch unit 9, and sent by the timing control unit 10 Under the control of the enable signal and the clock, the parallel / serial conversion unit 3 completes the parallel / serial conversion of the output data of the latch unit 9 .

[0029] Under the control of the enable signal and clock sent by the timing control unit 10, the synchronous serial port unit 4 performs multimedia data communication, and the s...

Abstract

This invention relates to a transmission method and its application device for remote monitor data for solving the problem of unstable monitor system resulted from software reform on the basis of using transmission channel bandwidth as much as possible. This invention applies the following technology: an asynchronous serial interface outputs the data to a serial / parallel switch unit to finish the switch then the data is put in a latch unit which outputs it to a parallel / serial switch unit for switching then to be output to a synchronous serial multiplex unit multiplexed with the data to the unit from the synchronous serial interface to occupy a time slot together which is output to a time slot exchange unit exchanging it to a definite time slot to be merged with PCM stream from the slave E1interface and output from the master E1 interface.

Description

technical field [0001] The invention relates to a remote monitoring data transmission method and its implementation device, in particular to a data transmission method and its implementation device in a remote monitoring system in the telecommunication industry. Background technique [0002] In the telecommunications industry, PCM resources for remote monitoring systems are very limited, and a 64K time slot is often used to transmit compressed multimedia data such as images and voices and data collected by smart devices at the same time. The existing method usually packs multimedia data and collected data together, transmits them according to a certain protocol, and then unpacks the data according to the protocol in the data processing center. If a different protocol is used, the software needs to be changed. Application number: 99124690.X, Publication number: CN1302136A The invention patent application of CN1302136A on July 4, 2001 disclosed th...
