Detailed Description
The invention will be described in detail hereinafter with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
Fig. 1 is a flowchart of an optical module access processing method according to an embodiment of the present invention, where the method includes:
step S102, judging whether the optical module is in a state of being capable of being accessed currently;
step S104, in response to the query request of the application, returns to the application whether the optical module is currently in a state that can be accessed, so that the application determines whether to access the optical module.
By the method, before each access to the optical module such as the SFP, the effective access opportunity is obtained in the above manner, so that the effectiveness of each access is greatly ensured, and the phenomena of time sequence disorder (for example, I2C (also called IIC, Inter IC bus, a serial expansion technology, originally proposed by PHILIPS company, providing a communication line between integrated circuits) caused by the access in improper time, even the optical module is rewritten, and the like are greatly reduced. The method is particularly suitable for PON (passive optical network) (including EPON, GPON and NG-PON) and other system equipment which requires high stability, reliability and efficiency for the access of the optical module.
It should be noted that the above method is applicable to various situations that affect whether the optical module can be normally accessed, and for various situations, the application software can very conveniently determine whether the optical module is accessible, so as to determine whether to continue to access, thereby very well ensuring the effectiveness of the application software in accessing the optical module. The following exemplary description describes two general specific implementation processes for determining whether an optical module is currently in an accessible state in the method under the condition that normal access is affected:
(1) judging whether the optical module is inserted or pulled out according to a signal from the optical module; and if the optical module is plugged in, determining that the optical module is in the state which can not be accessed currently.
In a preferred embodiment, when the optical module is determined to be inserted, it is determined that the optical module starts to be in a state where the optical module can be accessed after a first preset time. The method fully considers the condition that a certain buffer time is needed from power-on to the accessible state of the general optical module, so that the access state of the optical module is more accurately grasped.
In order to facilitate a Central Processing Unit (CPU) executing the application software to obtain such status information, a value of an in-place indication register of a corresponding optical module may be set to be ONLINE (ONLINE) when the optical module is determined to be in an accessible state; under the condition that the optical module is determined to be in the state incapable of being accessed, the value of the in-place indication register of the corresponding optical module is set to be OFFLINE (OFFLINE), so that the application can read the in-place indication register of the optical module to be accessed, and determine whether to access the optical module according to the value of the in-place indication register. By this method, CPU can judge the current access state of optical module conveniently.
(2) When an indication for triggering a received signal strength indication Trigger (RSSI Trigger, abbreviated as RSSI _ TRI) signal is received, it is determined that the optical module is currently in a state that the optical module cannot be accessed, and it is determined that the optical module starts to be in a state that the optical module can be accessed when a difference between the current time and a time when the indication for triggering the RSSI _ TRI signal is received last time reaches a second preset time.
Preferably, after receiving the indication for triggering the RSSI _ TRI signal, before determining that the optical module starts to be in a state where the optical module can be accessed, the RSSI _ TRI signal is set to a high level, after waiting for a third preset time, the RSSI _ TRI signal is set to a low level, and a fourth preset time is waited, wherein the second preset time is the third preset time plus the fourth preset time.
In order to facilitate the CPU executing the application software to acquire such status information, the value of the RSSI signal indication register of the corresponding optical module may be set to RSSI available (RSSI _ OK) when it is determined that the optical module is in a state where it can be accessed; and under the condition that the optical module is determined to be in the state of being incapable of being accessed, setting the value of the RSSI signal indication register of the corresponding optical module as RSSI BUSY (RSSI _ BUSY). Therefore, the application can read the RSSI signal indication register corresponding to the optical module to be accessed, and determine whether to access the optical module according to the value of the RSSI signal indication register. By this method, CPU can judge the current access state of optical module conveniently.
Fig. 2 is a block diagram of a structure of an optical module access processing apparatus according to an embodiment of the present invention, and as shown in fig. 2, the apparatus includes: the judging module 22 is configured to judge whether the optical module is currently in an accessible state; and the query module 24 is configured to return the determination result of the determination module 22 to the application in response to a query request of the application, so that the application determines whether to access the optical module.
Preferably, the judging module 22 is used for judging whether the optical module is inserted or pulled out according to a signal from the optical module; and if the optical module is plugged in, determining that the optical module is in the state which can not be accessed currently.
Preferably, the judging module 22 may be further configured to determine that the optical module is currently in a state that cannot be accessed when receiving an indication for triggering the RSSI _ TRI signal; and when the difference value between the current time and the time when the indication triggering the RSSI _ TRI signal is received last time reaches a second preset time, determining that the optical module is in a state of being capable of being accessed.
The apparatus may be implemented by software, or may be implemented by a programmable Logic Device such as a Complex Programmable Logic Device (CPLD), or a combination of both.
The present embodiment further provides an optical module access processing apparatus, including: the CPLD is used for judging whether the optical module is in a state capable of being accessed currently or not and recording a judgment result in a state register of the CPLD; and the Central Processing Unit (CPU) is configured to receive an inquiry request from an application, read the status register of the CPLD, obtain a judgment result, and return the judgment result to the application, so that the application determines whether to access the optical module.
In the device, a protection module is realized by a CPLD, the protection module runs independently of a CPU and the like, that is, after programming is set, the protection module in the CPLD may be used for inquiring the plugging and unplugging condition of an optical module and the information such as RSSI (received signal strength indicator) signals and the like all the time, then obtaining the conclusion whether the optical module is in an accessible state or not, and then storing the conclusion into a specific state register of the CPLD. On the other hand, if the CPU receives an access request of an application to the optical module, the CPU first accesses the status register of the CPLD to obtain whether the corresponding optical module is in an accessible state, and if the optical module is in the accessible state, then accesses the optical module through I2C.
The following described embodiments 1-3 combine the technical solutions of the above described preferred embodiments.
Example 1
Fig. 3 is a schematic diagram of a position of a protection module in a system according to embodiment 1, and as shown in fig. 3, a protection module (which functions like the determination module in the optical module access processing apparatus) is added before a conventional I2C timing implementation module, and a previous protection measure is performed before the I2C timing of the optical module starts, so that the access reliability can be effectively improved. The protection module can be realized by software, or by a programmable logic device such as a CPLD, or by the combination of the two.
In the method, each time the optical modules such as the SFP and the like are accessed, the protection module is required to be started firstly, so that an effective access opportunity is obtained, and the access reliability of the optical modules such as the SFP and the like is greatly improved. The following is a detailed description:
in this embodiment, a set of I2C buses is used in the PON system to mount a plurality of SFP optical modules, and the protection module is mainly implemented by a CPLD. Since a certain time is required from power-on to an accessible state of a general pluggable optical module (depending on different optical modules), it is necessary to introduce this protection into the protection module. In addition, when the received optical power information RxPower of the optical module is collected, the RSSI _ TRI signal needs to be triggered to start the received optical power conversion of the single chip microcomputer in the optical module. During the period of RSSI _ TRI trigger (200-500 microseconds, depending on the specific optical module), the optical module is in an inaccessible state (as shown in fig. 4), so that this portion also needs to be introduced into the protection module in the CPLD.
Example 2
This embodiment describes in detail a protection process for optical module plugging and unplugging, and fig. 5 is a flowchart of the protection process for optical module plugging and unplugging according to embodiment 2, and the process includes the following steps:
step 501, detecting a signal caused by plugging and unplugging an optical module;
step 502, judging whether the optical module is pulled out or inserted, if the optical module is inserted, executing step 503, and if the optical module is pulled out, turning to step 505;
step 503, delaying waiting for a period of time;
step 504, setting an in-place indication register of a corresponding optical module in the CPLD as ONLINE, and turning to step 501;
and 505, setting the in-place indication register of the corresponding optical module in the CPLD as OFFLINE, and continuing to execute downwards.
Example 3
This embodiment describes the protection process for the RSSI _ TRI signal in detail, and fig. 6 is a flowchart of the protection process for the RSSI _ TRI signal according to embodiment 3, including the following steps:
step 601, receiving an indication for triggering an RSSI _ TRI signal;
step 602, setting an RSSI signal indication register in the CPLD as RSSI _ BUSY;
step 603, pulling up the RSSI _ TRI;
step 605, pulling the RSSI _ TRI signal low;
step 606, delay a certain time;
and step 607, setting the RSSI signal indication register in the CPLD as RSSI _ OK.
From the above description, it can be seen that in the solutions provided in the above embodiments, what the CPU needs to do is relatively simple through the above protection module, before accessing the I2C optical module each time, the optical module in-place indication register and the RSSI signal indication register in the CPLD are read first, and only when the value of the optical module in-place indication register is ONLINE and the value of the RSSI signal indication register is RSSI _ OK, the optical module can be accessed.
It will be apparent to those skilled in the art that the modules or steps of the present invention described above may be implemented by a general purpose computing device, they may be centralized on a single computing device or distributed across a network of multiple computing devices, and alternatively, they may be implemented by program code executable by a computing device, such that they may be stored in a storage device and executed by a computing device, or they may be separately fabricated into various integrated circuit modules, or multiple modules or steps thereof may be fabricated into a single integrated circuit module. Thus, the present invention is not limited to any specific combination of hardware and software.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
