Upper computer, transceiving processing terminal machine and program loading system

Abstract

The invention discloses an upper computer, a transceiving processing terminal machine and a program loading system. The transceiving processing terminal machine comprises at least one single board and an interface board, wherein the at least one single board comprises an interface chip of a preset bus protocol, and the at least one single board is mutually connected with the interface board by the preset bus protocol; and the interface board is used to load and update programs for the at least one single board according to the preset bus protocol under control of the upper computer. According to the invention, hard wire connection is replaced by a software protocol and the programs are updated externally in real time by the bus protocol, so that the system becomes simple and flexible, and actual engineering application effects are good; a simulator is not needed, so that various unstable factors related to interfaces caused by use of the simulator are reduced, and the system becomes more reliable; the transceiving processing terminal machine is only equipped with a few of external cables, and the system has good electromagnetic compatibility performance; and expansion and clipping can be implemented according to different quantities of the single boards in the system, and the applicable scope is wide.

Description

technical field [0001] The invention relates to the field of automation, in particular to a host computer, a sending and receiving processing terminal and a program loading system. Background technique [0002] At present, the transceiver processing terminal of communication terminal equipment often needs to update the program of the single board during the test. The traditional update method needs to open the case cover and take out the single board to update the program. This update method consumes manpower and material resources, especially in the transceiver processing terminal After assembly, the case cover cannot be opened to test and update the program, which brings great inconvenience to the actual engineering application. [0003] The traditional external program loading system of the transceiver processing terminal uses the program loading interface of all single boards (generally, the joint test action group (JointTestActionGroup, referred to as JTAG) is drawn out...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned system can solve the problem that the external program of the transceiver processing terminal cannot be loaded, it needs to be connected to an emulator, and too many connections require a dedicated control board for gating. The whole system is relatively complicated and the reliability is not high.
