Description
Technical field
The present invention relates to a kind of implementation method of integrated circuit board in-place detection.
Background technology
In control system, the interconnected card insert type structure that generally adopts between the integrated circuit board is made of a backboard and several piece integrated circuit board usually, and as shown in Figure 1, several piece integrated circuit board 11 is by the connector 13 and backboard 10 socket connections of connector 12 on it and backboard.Owing to need the tenaculum hot-line insertion and extraction, therefore, when important integrated circuit board powers on, must detect oneself and whether be connected (detection that is integrated circuit board signal on the throne) reliably, with decision and backplane interface Signal Processing with the interface signal of backboard.If integrated circuit board can not detect signal on the throne reliably, signal that may the toward back plate output error during its warm swap then, the normal operation of EVAC (Evacuation Network Computer Model).
The design of integrated circuit board input on the throne generally is on backboard and card connector, defines specific level, do on the respective signal of integrated circuit board opposite on drop-down processing, if integrated circuit board is read the level on the backboard, then think to be connected with backboard reliably.At present the specific design to the detection of integrated circuit board signal on the throne has two kinds of methods:
1) as shown in Figure 2, between backboard 10 and integrated circuit board 11, only design a signal 14 on the throne, and the contact pin length of this signal on the throne on connector 12 or 13 is identical with other signal pin length, as long as integrated circuit board is read signal on the throne and just thought that integrated circuit board has been connected with backboard reliably.This method is adopted in most of at present design.
The shortcoming of this method is: it has only designed an integrated circuit board signal on the throne, and the long pin with the normal signal line of the pin of this signal is long consistent.When the plug integrated circuit board, owing to can not do absolutely accurately on the process structure, the power or power-down of signal on the throne and normal signal line order might be inconsistent.When signal on the throne power on prior to the normal signal line or after in its power down, it is own on the throne that integrated circuit board is thought, beginning or continue it when on the throne the work that should do, and in fact some important holding wire does not contact with the holding wire of backboard, will bring some hidden danger like this.For example, two integrated circuit boards of active and standby usefulness each other, when the main board card is pulled out, standby integrated circuit board should be upgraded to main using in the shortest time, normal to guarantee this function that integrated circuit board is supported, but plate holding wire on the throne is not pulled out if the normal signal line of main board card is pulled out, mainboard with regard to think own still main with and forbid that the standby master of liter uses, this moment, this system just was in a dereliction with under the state of integrated circuit board, thereby may cause some unpredictable faults.
2) second method is similar to last a kind of method, difference is that connector adopts the long and short hands designing technique, also referring to shown in Figure 2, the contact pin length of plate signal 14 on the throne is shorter than the contact pin length of other signals 15, and plate signal on the throne is connected with backboard at last when guaranteeing to insert integrated circuit board.
For this method, though it does not have the defective of first method,, can increase the complexity of connector owing to complex process, improve the cost of backboard.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of integrated circuit board detection method on the throne in the system that draws, and solves in the prior art scheme plate signal on the throne and normal signal is asynchronous and problem such as system process complexity.
For achieving the above object, technical scheme of the present invention specifically is achieved in that
A kind of integrated circuit board in-place detection method, wherein integrated circuit board and backboard have connector respectively, and integrated circuit board is connected by connector with backboard, and this method may further comprise the steps at least:
Two groups of plate signals on the throne are set respectively on the connector of integrated circuit board and backboard, and these two groups of plate signals on the throne place the upper and lower of back panel connector and card connector respectively;
The level value of plate signal on the throne is set on backboard, on integrated circuit board, makes opposite level and handle;
If the level of these two groups of plate signals on the throne is consistent and with the described level value that is provided with when identical, judge that then integrated circuit board reliably is connected with backboard, this integrated circuit board is on the throne, otherwise judges that this integrated circuit board offs normal.
According to the invention described above technical scheme, described two groups of plate signals on the throne can place the top of connector and bottom respectively.
According to the invention described above technical scheme, described two groups of plate signals on the throne take a holding wire respectively, and two groups of plate signals on the throne use this two holding wires altogether.
This shows that integrated circuit board in-place detection method provided by the present invention has following characteristics and advantage:
Simple and practical, both improved the reliability of system widely, can not increase cost yet, so not strict to the technological requirement of backboard simultaneously yet.
