Realize the major function of card insert type testing apparatus, traditional method for designing is to adopt single data processing unit (as CPU, DSP etc.), on backboard, utilize address/data bus or communication interface (as serial ports, I2C etc.) to expand each functional module, realize the needed function of testing apparatus.As shown in Figure 2, processing unit is drawn address bus (A ［ 24:0 ］), data bus (D ［ 15:0 ］), read-write and is controlled WR/OE, chip selection signal (CS ［ 7:0 ］), look-at-me (IRQ[7:0]) backboard by the time, on backboard, each groove position is according to the design needs of the functional module of pre-installation, be assigned to different signals, discrete function module also needs serial communication, IO equisignal line.This design has following shortcoming: 1, because the function of module is different, corresponding groove position bus interface is different, causes different functional modules can only be arranged on fixing groove position, can not mixed insertion; 2, on backboard, address data bus signal quantity is many, has improved the design difficulty of core bus, has improved manufacturing cost; 3, the address data bus driving force of processing unit is limited, unless the design phase is reserved, otherwise be difficult to realize later stage function, expands; 4, interface signal is complicated, and the replaceability of module is poor, once certain module stops production, is difficult to find substitute products.5, processing unit will be controlled all functional modules, has improved the difficulty of Software for Design.
[utility model content]
The purpose of this utility model is effectively to overcome the deficiency of above-mentioned technology, and a kind of card insert type automated test device of core bus Network Based is provided.
The technical solution of the utility model is achieved in that it comprises processing unit, backboard, power module and a plurality of functional module, and described power module is electrically connected on backboard, so that electric energy to be provided; On described backboard, there is a plurality of grooves position, described functional module comprises standard source module, standard scale module, switching value module and communication interface modules, and standard source module, standard scale module, switching value module and communication interface modules are plugged on the groove position of backboard; Described processing unit inside is provided with processor and switch, described switch can be communicated by letter with above-mentioned standard source module, standard scale module, switching value module and communication interface modules by the network being arranged in backboard, described processor can realize and standard source module, standard scale module, switching value module and communication interface modules between exchanges data.
In above-mentioned structure, also have communication interface on described processing unit, described processing unit is connecting a user interface UI by this communication interface.
In above-mentioned structure, described processor is CPU or DSP.
In above-mentioned structure, have a plurality of network interfaces on described switch, the network interface of switch connects each above-mentioned groove position by backboard.
The beneficial effects of the utility model are: the utility model designs switch at processing unit, and the network interface of switch connects each groove position by backboard, the corresponding network interface in each groove position; All groove positions are according to identical Design of Signal, and on backboard, the signal of each groove position is identical, and therefore above-mentioned functional module just can be arranged on arbitrarily different groove positions, thereby has simplified Interface design, makes the simplicity of design of core bus easy; Because network service possesses very strong driving force, the later stage is easy to practical function expansion, and the needed number of signals of network service is few, has simplified back plate design difficulty, reduces manufacturing cost.
