Referring to fig. 2, fig. 2 is a schematic diagram of a preferred embodiment of an ATE tester frame apparatus according to the present invention. Each serial port communication module comprises a serial port communication cable and a serial port communication switch, and the serial port communication switch receives a panel mode and/or a back plate mode instruction input by a user from the line card side plate host and starts remote collection of serial port information.
Referring to fig. 3, fig. 3 is a schematic diagram illustrating an implementation manner of a side plate of a line card according to an embodiment of the present invention. As shown in fig. 3, the line card side board host 1 is described as an example.
Firstly, sending by a host 1 of a side plate of the line card
The serial port communication data sent by the line card side plate host 1 is gated by a serial port communication switch, and the broadcast mode is selected to be a backboard interface, a panel interface or a broadcast mode with both channels being gated.
The gating of the communication switch is determined by an activity detection module, which has 3 input sources:
I. whether a panel serial port cable is inserted or not;
II, whether the panel receiving direction detects effective serial port data or not is judged;
and III, the line card side plate host 1 forcibly configures the gating of the communication switch through a low-speed access bus.
The input source 3 has the highest priority, and the three input sources and gating relations are as follows:
② line card side board main board 1 receiving
The serial port communication switch of the line card side plate can receive serial port communication from a back plate (issued from a main plate) and a panel, specifically receives which source (such as the line card side plate main plate 1) through validity (activity) detection module gating, and can only support 1 data source while the receiving direction does not support broadcasting, namely, the gating relation of the receiving direction is similar to the sending direction and only does not support broadcasting.
Referring to fig. 4, fig. 4 is a schematic diagram illustrating an implementation manner of the main board side according to the embodiment of the invention. As shown in fig. 4, the serial port communication Hub module includes a bus switch, an uplink buffer, a bus access module, and a downlink buffer; the bus switch is used for receiving serial port communication data gated according to the first priority processing rule and storing the serial port communication data into an uplink buffer, and the gating of the bus switch is configured by the bus access module between the host 0 and the communication hub.
That is to say, the host 0 controls the downlink buffer to buffer the serial communication data received from the bus access module, and the bus switch selects one path of the serial communication data as the current serial communication data according to a second priority processing rule and sends the serial communication data to the host of the corresponding line card side plate; the second priority processing rule is that M groups of serial port communication data are processed according to a first-in first-out queue, a high-priority first-out queue is selected according to configured priority, or only one path of output processing in the M groups is gated according to configuration.
The main control board further comprises a data buffer, and after the host 0 receives a data sending request sent by the line card side board host, the serial port communication data is buffered into the data buffer; correspondingly, after receiving the data sending request sent by the upper computer, the host computer 0 caches the serial port communication data into a data buffer. The communication link is an internet access or serial port communication link.
Seen from the main control panel side:
(ii) a sending direction
It should be noted that the transmission direction refers to transmission of the line card side board host. And the serial port communication hub on the main control board receives serial port sending data sent by all the line card side plate hosts. The bus switch gates 1 of the channels and stores data into an upstream buffer (TX buffer), and the gating of the bus switch is configured by an access bus between the host 0 and the serial port communication hub. The upstream buffer continuously buffers the data and signals the depth of the buffer to the bus access module by an indication.
The host 0 may actively access the bus to read the data in the uplink buffer, or report an interrupt by the serial port communication hub after the buffer depth of the uplink buffer reaches half, and notify the host 0 to read the data. The host 0 sends the read data out through the network interface via a network protocol such as SSH.
② direction of reception
It should be noted that the receiving direction refers to the receiving direction of the line card side board host. After receiving a network data request sent by an external host (upper computer), the host 0 caches the data in a data buffer (data buffer), simultaneously initiates access bus writing, writes the data in a downlink buffer (RX buffer), feeds back a receiving indication signal in real time by the downlink buffer, and if the data is found to occupy 80% of the buffer depth, feeds back an interrupt to the host 0 and stops writing. The host 0 turns to receive the indication to obtain the real-time buffer depth of the downlink buffer, and starts to rewrite the remaining data after the downlink buffer is idle.
And the bus switch selects one path of line card, sends out the data in the downlink buffer, and finally sends the data to the line card side plate host.
In the actual process, the above functions can support a serial bus access message program (serial _ connect) through software on the main control board, realize the selective receiving and the serial port of which line card side plate SLOT is sent to be in butt joint, convert the user issued command into serial port data to be sent, and simultaneously output the return message of the serial port to the ssh terminal. Through connecting different ply-yarn drill curb plate SLOT, can be comparatively convenient carry out the long-range collection of serial ports information.

step S312: the host 0 reads the data in the uplink buffer by accessing the bus module, or after the depth of the uplink buffer reaches half, the serial port communication Hub module reports an interrupt and informs the host 0 to read the data;
the transmission direction step S32 includes:
step S321: after receiving a data request sent by the upper computer, the host computer 0 caches the data into a downlink buffer and simultaneously initiates the access bus module to write, and the downlink buffer feeds back a receiving indication signal in real time;
step S322: if the data of the downlink buffer occupies X% of the buffer depth, feeding back an interrupt to the host 0, and stopping writing; wherein, the X% is more than or equal to 60%;
step S323: and the host computer 0 rounds to train and receive the indication signal so as to obtain the cache depth, and when the cache depth of the downlink buffer is less than X%, the residual data is rewritten.
9. The method for uniformly collecting serial ports of ATE tester frame-type equipment according to claim 8, wherein X% is 80%.
