Benefits of technology

This technology allows for continuous testing while keeping things running smoothly even if they are connected through different types of interfaces like serial ports with multiple chips attached together.

Problems solved by technology

Technological Problem: Current communication systems equipments used in electronic products require testing before they go into use. However, current methods may result in inconsistence between different parts of the device being tested, leading to instabilities overtime which affects their performance negatively. Additionally, existing solutions only work well when applied correctly but cannot detect any issues related to poorly maintained circuitry within them.

Embodiment Construction

[0035] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0036] Such as figure 1 As shown, a communication system device usually includes multiple equipment single boards, a main control board and a backplane, and the multiple equipment single boards and the main control board are connected through the backplane. On the basis of the above structure, the present invention provides a communication system device with an online test function by adding an online test chain between each single board and an online test controller for managing a test database, which is mainly based on JTAG standard in-circuit test, so if figure 1 As shown, in the device of the present invention, the main connection relationship includes the following parts:

[0037] (1) Equipment single board and its JTAG online test chain 101, that is, on each equipment single board, the online test ports (such as JTAG test ports) of i...

Abstract

The invention discloses a communicating system apparatus and detecting method thereof. The apparatus includes an on-line testing controller, connected to a master control board for managing a testing database, wherein the controller is used for distributing testing data and transmitting testing data sequences to apparatus boards through the master control board, or colleting testing data sequences from apparatus boards; and board external testing interfaces, respectively set up on the back board in one-to-one correspondence with the plurality of apparatus boards, wherein, on-line testing terminal ports of integrated circuit chips on each apparatus are connected in series to form a board on-line testing chain, the input-output terminal ports of the board on-line testing chain are connected onto the back board and the board external testing interface corresponding to the apparatus board. The invention can perform on-line or periodically failure testing and locating to the communicating system apparatus, preventing and maintaining the probable existing faults beforehand, thereby improving reliability of the communicating system apparatus.
