Abstract
The utility model relates to the data communication technology field, in particular to a device for infinite cascading of backplate signals among cabinets. The device comprises backplates, data-transmitting sub plates, data-receiving sub plates and receivers. The backplates are connected with the data-transmitting sub plates and the data-receiving sub plates via cables. The receivers are arranged on the data-transmitting sub plates and the data-receiving sub plates. Data-transmitting sub plate connectors and data-receiving sub plate connectors of the backplates of two to-be-connected cabinets are connected. The device of the utility model has the beneficial effects that the a method for signal cascading among multiple cabinet backplates well solves the limits to backplate signal cascading when cabinets are expanded to form large-scale systems, effectively lowering the design requirement on the volume of a single cabinet and therefore significantly reducing the overall system cost.
Description
Technical field
The utility model relates to the data communication technology field, relates in particular to backboard signal infinite cascade device between a kind of cabinet.
Background technology
At present, in the design of 19 inches rack-mount units of standard, often need a plurality of same equipment be carried out cascade, the backboard signal of a plurality of cabinets is carried out interconnected, with the increase total system capacity.
Present solution is that the size that strengthens backboard is combined into bigger cabinet; But this method is limited by the restriction of PCB production technology; Can not enlarge backboard arbitrarily system is enlarged, therefore need better method to make the signal of backboard between a plurality of cabinets carry out cascade.
Summary of the invention
The utility model is to overcome the weak point that exists in the prior art; It is backboard signal infinite cascade device between a kind of cabinet that purpose is to provide method; This device is that the backboard data are drawn out to the cabinet edge through veneer, is connected to the reception veneer of another cabinet then through cable, receives to deliver to this cabinet veneer again after veneer recovers signal; Realize the cascade in a plurality of cabinets that the backboard signal is unlimited, solved the problem that exists in the prior art.
The utility model is to achieve the above object through following technical scheme: backboard signal infinite cascade device between a kind of cabinet; Comprise backboard, data transmission daughter board, Data Receiving daughter board and connector; Backboard sends daughter board through cable and data and is connected with the Data Receiving daughter board; Connector is located at data and sends on daughter board and the Data Receiving daughter board, and the data of two cabinet backboards that need connect send the connector of daughter board and the connector of Data Receiving daughter board links to each other.
As preferably, on the connector of installing on data transmission daughter board and the Data Receiving daughter board radio receiving transmitting module is installed, can pass through the wireless method transmission of data signals each other.
The beneficial effect of the utility model: the limitation of backboard signal cascade when the device that is applied in signal cascade between the multiple cases backboard that the utility model proposes has well solved through cabinet expansion composition large scale system; Can effectively reduce designing requirement, thereby reduce the overall cost of system significantly the unit tankage.
Description of drawings
Fig. 1 is the device synoptic diagram of backboard signal infinite cascade between cabinet.
Label among the figure:
The 1-backboard; The 2-data are sent daughter board; 3-Data Receiving daughter board; The 4-connector; The 5-radio receiving transmitting module.
Embodiment
Embodiment 1: below in conjunction with specific embodiment the utility model is described further, but the protection domain of the utility model is not limited in this:
Backboard signal infinite cascade device between cabinet backboard cabinet; Comprise backboard 1, data transmission daughter board 2, Data Receiving daughter board 3 and connector 4; Backboard sends daughter board through cable and data and is connected with the Data Receiving daughter board; Connector is located at data and sends on daughter board and the Data Receiving daughter board, and the data of two cabinet backboards that need connect send the connector of daughter board and the connector of Data Receiving daughter board links to each other, and data are sent radio receiving transmitting module 5 is installed on the connector of installing on daughter board and the Data Receiving daughter board; Can pass through the wireless method transmission of data signals each other, as shown in Figure 1.
Concrete workflow comprises the steps:
1) design one blocks of data sends daughter board and blocks of data reception daughter board on each cabinet backboard;
2) the backboard signal sends daughter board and the exchange of Data Receiving daughter board through cable and data;
3) data are sent mounted connector on daughter board and the Data Receiving daughter board, and two cabinet backboard signals that need to connect are connected through the connector of data transmission daughter board and the connector of Data Receiving daughter board;
4) data are sent daughter board and are driven output or direct signal output according to cascade apart from enhancing signal;
5) the Data Receiving daughter board can carry out being sent to backboard or directly being sent to backboard after data are recovered according to signal quality;
6) any two cabinets can be according to the mutual cascade of the described method of step 1)-step 6), thereby realizes the unlimited cascade of backboard signal.
According to the needs of system's cascade system, each cabinet backboard can add a plurality of transmission daughter boards or the reception daughter board forms star-like or serially concatenated.
Data are sent radio receiving transmitting module 5 are installed on the connector of installing on daughter board and the Data Receiving daughter board, can pass through the wireless method transmission of data signals each other.
Above said be specific embodiment of the utility model and the know-why of being used; As if the change of doing according to the conception of the utility model; When the function that it produced does not exceed spiritual that instructions and accompanying drawing contain yet, must belong to the protection domain of the utility model.
