Description
Technical field
The present invention relates to industrial cable communicating technology field, more particularly, relate to a kind of emulation mode and device of automatic instruction system.
Background technology
Out of doors industrial production is on-the-spot or similarly than in the long distance work scene, generally all has automatic instruction system to be installed in the scene, and these systems are essential industry wire communication facilities that the region produces instruction, information issue.This type systematic is realized automatic connection by the calling subscriber with dial mode in use, realizes indivedual or colony's amplifying call, and called end adopts powerful broadcast ﹠ call, also can carry out the duplex conversation by end office (EO) between the user, realizes assigning of work order.The major function of system have exhale, conversation, group calling, two group calling, exhale together, tone-off detects, call out functions such as timing.System mainly is made up of main frame (mainly being made up of control switching part, power amplifier part, power unit), user end office (EO) (containing loud speaker), cable, the core of this type systematic is exactly program control control switching part, it finishes various continuities under the CPU software control, thereby reach every function of reserving in advance, realize the automatic exchange and the calling of user side interoffice.The control switching part is mainly continued by master control borad (CPU board), user's plate (SUB plate), speech channel, and partly (SW plate), individual amplifier section (AMP40 plate), group calling amplifier section (AMP04 plate), the note of exhaling are sent out a feeder panel (note is sent out feeder panel), signal plate (OSC plate), monitor board feature boards such as (MONI plates) and power unit formation.
Also be not used at present the general offline inspection equipment of the emulation automatic instruction system course of work, to the debugging of automatic instruction system with when safeguarding, master control borad (CPU board) software that then needs spare part, the repair member to various feature boards or changed confirms by present technology two kinds of methods are arranged:
First method be in this system directly on the machine operation verify that there is the problem of two aspects in this, the one, checking work can only be arranged in special time period (as the production unit annual overhaul of this system) to be carried out, otherwise can influence normal production communication; The 2nd, owing to move with regard to last machine, in case it is wrong and cause the possibility of system's misoperation or device damage to exist the software and hardware of feature board without off-line testing.So the method not only is restricted, and there is great risk on the proving time.
Second method is to use system simulation technology, makes up the general offline inspection equipment of the simulation automatic instruction system course of work.System simulation technology is to utilize essential process that takes place in the model reproduction real system and the technology of testing on model, and the existing systems emulation technology can be divided into physical simulation, mathematical simulation, semi-physical simulation by used implementation method.
