In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Fig. 1 is an external architecture diagram of a hard disk status indicator lamp control device according to an embodiment of the present invention. Only the portions related to the present embodiment are shown for convenience of explanation.
Referring to fig. 1, an external architecture of a hard disk status indicator control device provided in an embodiment of the present invention includes a back plate 1, a raid card 3 is built in the back plate 1, a plurality of hard disk slots for placing a hard disk 2 are formed in the back plate 1, and a plurality of hard disk status indicator lamps 5 are further disposed on the back plate 1; raid card 3 through the connecting wire respectively with backplate 1 with hard disk status indicator lamp controlling means 4 electric connection, hard disk status indicator lamp controlling means 4 still with a plurality of hard disk status indicator lamps 5 electric connection, a plurality of hard disk status indicator lamps 5 respectively with a plurality of hard disk grooves of seting up on backplate 1 are corresponding for instruct the state of putting into hard disk 2 in the hard disk groove. The hard disk state indicator lamp control device 4 is a CPLD.
Based on the external architecture of the hard disk status indicator lamp control device shown in fig. 1, the method for acquiring power consumption information provided by the embodiment of the present invention is described in detail below with reference to specific embodiments:
fig. 2 shows an implementation flow of a hard disk status indicator lamp control method according to an embodiment of the present invention, and in the embodiment shown in fig. 2, an execution subject of the flow is a hard disk status indicator lamp control device in fig. 1. The implementation process of the method is detailed as follows:
step S201, receiving an SGPIO BUS signal containing hard disk state information sent by a Raid card, wherein the SGPIO BUS signal comprises an SClock signal, a SLoad signal and an SDataOut signal.
In this embodiment, the Raid card sends the SGPIO BUS signal containing the status information of the hard disks to the CPLD through the Minisas interface of the backplane, the SGPIO BUS signal of each Minisas interface constantly sends the status information of 4 hard disks, and the backplane is generally provided with 8 hard disks, so two Minisas interfaces are required to send the status information of 8 hard disks, that is, the CPLD receives two groups of SGPIO BUS signals at the same time, and the processing modes of the two groups of SGPIO BUS signals are the same, so the embodiment of the present invention mainly explains the processing mode of one group of SGPIO BUS signals.
Step S202, judging whether the time that the SClock signal and the SLoad signal in the SGPIO BUS signal are simultaneously in a high level is less than a preset time threshold value; if yes, the process proceeds to step S203, otherwise, the process ends.
In this embodiment, the preset time threshold is 64ms, and when the time that the SClock signal and the SLoad signal are both high is longer than 64ms, it represents that the SGPIO BUS function is disabled, so that it is necessary to determine this condition before reading the SGPIO BUS signal, and if the time that the SClock signal and the SLoad signal are both high is longer than 64ms, an indication flag is set to "1", and the flow ends; otherwise, setting the indication flag to "0", and proceeding to step S203, reading the SGPIO BUS signal, where the reading and analysis of the data in the SGPIO BUS signal are both performed under the condition that the indication flag is "0".
Step S203, reading values of the SClock signal, the SLoad signal, and the SDataOut signal in the SGPIO BUS signal according to a preset frequency, and assigning the read values to preset variables delay _ SClock, delay _ SLoad, and delay _ sdaout, where bit widths of the variables delay _ SClock, delay _ SLoad, and delay _ sdaout are all greater than 1.
In the present embodiment, the bit width of the variable quantities delay _ sclock, delay _ slot, and delay _ sdaout is 3. The CPLD samples with a clock frequency of 50MHZ, reads the SClock signal, the SLoad signal and the SDataOut signal transmitted to the backplane at each falling edge of the clock frequency of 50MHZ, and assigns the read values to preset variables delay _ lock, delay _ Sload and delay _ SDataout respectively. Therefore, the CPLD can subsequently and respectively select a corresponding effective numerical value from the assigned variables delay _ SClock, delay _ slope and delay _ SDataOut for analysis, and the influence of burrs of the SClock signal, the SLoad signal and the SDataOut signal on the indication accuracy of the hard disk state indicator lamp is solved.
In step S204, the assigned delay _ sclock [ n ], delay _ slope [ n ], and delay _ sdaout [ n ] are analyzed, and at each falling edge of delay _ sclock [ n ], the value of one bit of delay _ sdaout [ n ] is given to another variable data _ temp, the bit width of the variable data _ temp is 12, and the values of 12 delay _ sdaout [ n ] can be added. Wherein, delay _ sclock [ n ], delay _ sload [ n ] and delay _ sdaout [ n ] respectively represent the nth value of the variables delay _ sclock, delay _ sload and delay _ sdaout, and n is a positive integer.
In the present embodiment, since the bit widths of the variables delay _ sclock, delay _ slot, and delay _ sdaout are all 3, each variable includes 3 values. In an embodiment, after the read values are assigned to the preset variables delay _ sclock, delay _ slope, and delay _ sdataout respectively, a second value is selected from the assigned variables delay _ sclock, delay _ slope, and delay _ sdataout for analysis, that is, the assigned variables delay _ sclock [2], delay _ slope [2], and delay _ sdataout [2] are analyzed, and at each falling edge of delay _ sclock [2], the value of delay _ sdataout [2] is assigned to another variable data _ temp.
Step S205, counting the number of the values of delay _ sdataout [ n ] contained in the variable data _ temp according to the value of delay _ sload [ n ], and assigning the value of data _ temp to another variable rec _ data after the assignment of the variable data _ temp is completed.
In this embodiment, each rising edge of the SClock signal, the Raid card transmits one bit of SLoad and SDataOut data, where the high level of SLoad is the start flag bit, and the SDataOut starts transmitting data of the 0 th hard disk when the low level of SLoad is low, and each 3 bits of data is status information of one hard disk, and 4 hard disks transmit 12 bits of data in total. When SDataOut transmits the 12 th bit of data, SLoad is high, which is the start flag of the next round of transmission, and the data transmission mode can be seen in fig. 3. Further, step S205 specifically includes:
at each falling edge of delay _ sclock [ n ], judging whether the value of corresponding one bit of delay _ slope [ n ] is '1';
if yes, the number of the values of delay _ sdataout [ n ] contained in the data _ temp is counted as zero; if not, adding 1 to count the number of the values of delay _ sdataout [ n ] contained in the data _ temp;
when the count is 11, the assignment of the variable data _ temp is completed, and the value of the data _ temp is assigned to another variable rec _ data.
As can be seen from the data transmission scheme shown in fig. 3, while the value of the corresponding one bit delay _ sdataout [ n ] is assigned to the other variable data _ temp at the falling edge of delay _ sclock [ n ], it is determined whether delay _ slot [ n ] is high, which represents the start, at the falling edge of delay _ sclock [ n ], and the count is 0 at this time, and whether delay _ slot [ n ] is low, which is incremented by 1, and when the count is 11, the data _ temp value is the status data of 4 hard disks, and the data _ temp value is assigned to the other variable rec _ data.
And step S206, reading the value of the variable rec _ data, grouping the value of the variable rec _ data according to a preset strategy, analyzing the grouped data respectively to acquire the state of each hard disk, and controlling a corresponding hard disk indicator lamp to indicate.
In this embodiment, after the data _ temp value is assigned to the variable rec _ data, the CPLD may extract the state data of 4 hard disks, analyze the state data to obtain the state of each hard disk, and control the corresponding hard disk indicator lamp to indicate the state data. Further, step S206 specifically includes:
reading the value of the variable rec _ data, grouping the value of the variable rec _ data into one group according to every 3 bits of data to obtain four groups of hard disk state data, wherein each group of hard disk state data corresponds to the state information of one hard disk;
and analyzing the state data of each group of hard disks respectively to acquire the state information of each hard disk and control the indication of a corresponding hard disk indicator lamp.
In this embodiment, the hard disk states include five types, where the hard disk states represented by the respective values of the 3-bit data are: "000": a disc is arranged; "100": reading and writing; "001": reporting an error; "010": positioning; and others: and (4) reconstructing.
In the embodiment, 4 pieces of hard disk state information are collected by adopting the variable data _ temp and the variable rec _ data, and the 4 pieces of hard disk state information are analyzed after being read all at once, so that each SDataOut data can be ensured to be read and correspond to the hard disk number, and the problems of unstable and incorrect indication of a hard disk state indicating lamp are solved.
Preferably, in this embodiment, before analyzing the hard disk state data, the method may further include:
detecting whether the level of a GND pin of a hard disk slot is low;
if the level is low, analyzing the hard disk state data corresponding to the hard disk slot to acquire the state of the hard disk in the hard disk slot and control a corresponding hard disk indicator lamp to indicate;
if the level is high, the hard disk state data corresponding to the hard disk slot is not analyzed, and the hard disk indicator lamp corresponding to the hard disk slot is controlled to keep in an off state.
Because whether the hard disk slot is connected with the hard disk cannot be known through the SGPIO signal, the GND pin level of the hard disk slot is used for judging whether the slot is connected with the hard disk in the embodiment, and if the slot is connected with the hard disk, the GND pin level is a low level; if the hard disk is not connected, the GND pin belongs to a suspended high-resistance state, and the electrical level of the GND pin is high, so that when the hard disk slot does not have a hard disk, the hard disk indicator lamp corresponding to the hard disk slot is directly kept in an off state, when the hard disk is arranged in the hard disk slot, the hard disk state data corresponding to the hard disk slot is analyzed, and the hard disk state indicator lamp corresponding to the hard disk slot is controlled to indicate according to the analysis result, so that the analysis efficiency of the CPLD can be improved.
As can be seen from the above, in the hard disk state indicator lamp control method provided in this embodiment, after the values of the SClock signal, the SLoad signal, and the SDataOut signal in the SGPIO BUS signal are read, the read values are assigned to preset variables delay _ SClock, delay _ slope, and delay _ sdaout, bit widths of the variables delay _ SClock, delay _ slope, and delay _ sdaout are all greater than 1, and then the variables delay _ SClock [ n ], delay _ slope [ n ], and delay _ sdaout [ n ] are selected from the assigned variables delay _ SClock, delay _ slope, and delay _ sdaout to perform analysis, so that the influence of the SClock signal, the SLoad signal, and the SDataOut signal on the accuracy of the hard disk state obtained can be solved; since the value of the corresponding one bit delay _ sdataout [ n ] is given to another variable data _ temp at the falling edge of each delay _ sclock [ n ], the bit width of the variable data _ temp is 12, and 12 values of delay _ sdataout [ n ] can be put; counting the number of values of delay _ sdataout [ n ] contained in the variable data _ temp according to the value of delay _ sload [ n ], and assigning the value of data _ temp to another variable rec _ data after the assignment of the variable data _ temp is completed; the method comprises the steps of reading the value of the variable rec _ data, grouping the value of the variable rec _ data according to a preset strategy, analyzing grouped data respectively to obtain the state of each hard disk, and controlling the indication of a corresponding hard disk indicator lamp, so that each SDataOut data can be read and corresponds to the number of the hard disk, and the problems of instability and inaccuracy of the indication of the hard disk state indicator lamp are solved.
