Description
Technical field
The present invention relates to the communications field and electronic applications, particularly relate to a kind of interface arrangement that is used to electronic equipments such as veneer that communication interface is provided.
Background technology
In the communications industry and electron trade, in order to guarantee the normal operation of system, usually need the veneer in the system is debugged, so that the actual functional capability of veneer meets the expection requirement of design.At present, the normal adjustment method that adopts is to set up being connected between data handling system such as computing machine and the veneer, by data handling systems such as computing machine visit veneer, realizes the data communication between the two, and finishes the debugging to veneer.
In the prior art,, often the interface circuit that is specifically designed to debugging need be set on veneer in order to realize the connection of veneer with data handling systems such as computing machines.What is called is specifically designed to debugging and refers to, and this interface circuit only just is used when the debugging veneer.Described interface circuit generally includes network port circuit or serial port circuit, and the interface circuit of each veneer is identical.
Seeing also Fig. 1, is the single plate structure synoptic diagram that has interface circuit in the prior art.Veneer 100 is provided with interface circuit, and described interface circuit comprises serial port chip 101, serial port connector 102 and network interface chip 104 and network interface connector 103.Serial port connector 102 that veneer has by self or network interface connector 103 can directly be connected with the serial ports or the network interface of data handling systems such as computing machine, thereby set up the data communication channel between the two, and finish the debugging to veneer.
In actual applications, the interface circuit that has owing to veneer self is commonly used in the debug process, and use is less when normal working of single board, thereby the probability that interface circuit damages is less.Therefore, when veneer was scrapped because of the damage of components and parts commonly used or be idle, the device in the interface circuit was intact often.These intact devices have caused great waste because of scrapping or leaving unused of veneer do not re-use.Like this, just make that interface circuit is set comes cost that veneer is debugged higher on veneer.
In addition, on the existing veneer a plurality of network interfaces or serial ports can be set.Yet, in actual debug process, only need use an interface usually, and other interfaces being left unused, this has caused waste equally.And, if on veneer, only be provided with network interface, and when using, reality needs serial ports, because network port circuit is soldered, can't be replaced by serial port circuit.Otherwise, as the same.Like this, just make in actual debug process, option interface at random, thus cause versatility relatively poor.
At present, for the versatility that improves interface circuit and reduce cost, the interface circuit that is provided with on the veneer is usually taked choosing weldering circuitry measures.Just, when producing veneer, can not weld some chip (for example serial port chip or network interface chip) earlier, but welding voluntarily according to actual needs in the course of the work, just weld the network interface chip when for example needing the network interface interface, just weld serial port chip when needing serial interface, so just improve the versatility of interface circuit, and saved cost effectively.
Although, can on veneer, design and install network interface and serial interface circuit in the prior art, realizing veneer, and then finish debugging to veneer with the connection between the data handling systems such as computing machine.But in actual applications, still there is following defective inevitably in said method:
One, the cost height.Owing to need debug, therefore, just need on each veneer, be provided for the interface circuit that connects with data handling systems such as computing machines, and then finish the debug process of data handling system such as computing machine veneer to each veneer in the system.Because the interface circuit on each veneer is identical, it is higher to make on veneer design and mounting interface circuit debug the cost of veneer.In addition, although veneer can adopt the measure of choosing weldering circuit when the design and installation interface circuit, existing choosing is welded circuit often only at chip, and not at capacitance resistance ware.And in the practical application, be exclusively used in and have a large amount of capacitance resistance wares in the interface circuit of debugging single board, and wherein a lot of capacitance resistance ware is not utilized, and this has wasted resource equally, causes cost higher.
Its two, reliability is low.Because the structure of veneer and the restriction of size, in actual the use on the veneer density of components and parts higher.In this case, if also need on veneer, design complete network interface or serial interface circuit, can make that then this nervous wiring space is more nervous.Like this, too Jin Zhang wiring space and too compact components and parts layout tend to cause the phase mutual interference between the components and parts, thereby make that the reliability of veneer is lower.
Its three, debugging efficiency is lower.Owing to design on the veneer, interface circuit is installed,, often need debug described interface circuit early stage in the exploitation of veneer in order to guarantee the correctness of this interface circuit design.Be the correctness of each single board interface circuit in the assurance system, just need all debug that this will make that the efficient of whole debug process is lower to the interface circuit of each veneer.
The 4th, the construction cycle is long.In the prior art, exploitation early stage need be on veneer the design and installation interface circuit, in case mistake appears in interface circuit design, will cause veneer normally not use, and need correcting, thereby prolong the construction cycle.
Summary of the invention
