field

The present disclosure generally relates to the field of circuit protection technology, and more specifically to a driver loading method, device, wireless access device and storage medium.

background

SLIC is the abbreviation of Subscriber Line Interface Circuit, which refers to the interface circuit between the switch and the user's phone. It is currently commonly used between digital wireless access point AP and user's phone. The specific connection relationship is shown in Figure 1.

The user's phone is not connected to the power supply. The voltage required by the phone when working comes from the two telephone line signals, so the SLIC must be able to supply power to the phone. When the phone rings, the voltage will reach 90V AC effective value, so the SLIC also needs an external boost circuit.

SLIC itself cannot identify the external Boost circuit situation. The SLIC driver can only be set to the PNP Boost solution or the NMOS Boost solution. Since the two Boost control circuit solutions have opposite transistor conduction levels, if the wrong driver is downloaded, the SLIC Boost circuit will not work and may even burn out the transistors over time.

Details

In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

The present disclosure will be described in further detail below in conjunction with the accompanying drawings and embodiments.

An embodiment of the present disclosure provides a method for loading a driver program, as shown in FIG2 , the method comprising:

Step 201: Control the user line interface circuit to output a high level voltage to the Boost control circuit;

Step 202: Read the Isen register data in the subscriber line interface circuit; and

Step 203: Load a driver corresponding to the Boost control circuit according to the Isen register data.

In the related art, in order to solve the problem of SLIC Boost control circuit self-adaptation, the method adopted is: by setting a dedicated detection IO in the SLIC circuit, manually configuring the IO The high level or low level allows the host AP to detect the high and low levels of the IO, determine whether the boost circuit solution of the SLIC circuit is a triode solution or a MOS tube solution, and then load the corresponding driver.

This method requires identifying the high and low levels of the manually set detection IO, and there may be a situation where an error is uploaded, or there may be a situation where the external detection IO is not set, resulting in the inability of the compatible driver to function.

The SLIC Boost control circuit adaptive method provided in this embodiment does not require an additional external detection circuit. It uses the characteristics of the conduction levels of the two boost circuit transistors to detect the presence or absence of feedback current, determine the SLIC Boost control circuit solution, and then load the corresponding SLIC driver program to avoid downloading the wrong driver program, which may cause the Boost control circuit transistor to burn out.

In some embodiments, the SLIC external boost circuit in this embodiment includes a PNP Boost control circuit and an NMOS Boost control circuit, as shown in Figures 3 and 4, respectively. In some embodiments, the loading of a driver corresponding to the Boost control circuit according to the Isen register data includes: judging whether Isen has current according to the Isen register data; if Isen has current, loading a driver corresponding to the NMOS Boost control circuit; if Isen has no current, loading a driver corresponding to the PNP Boost control circuit.

In certain implementation schemes, when controlling the subscriber line interface circuit to output a high level voltage to the Boost control circuit, the PWM pin of the subscriber line interface circuit may be controlled to output a high level voltage to the Boost control circuit.

In some embodiments, in order not to damage the transistor, the user line interface circuit can be controlled to output a high level voltage to the Boost control circuit within a first duration. The first duration can be set based on the situation. Specifically, when setting, the first duration should be set to a smaller value, for example, 100ms. In this way, the duration of outputting the high level voltage to the Boost control circuit is shorter, thereby not damaging the transistor.

The driver loading method provided by the present invention does not require the addition of an external detection circuit. It utilizes the characteristics of the transistor conduction level in the two Boost control circuits to detect the presence or absence of feedback current, determine the currently used Boost control circuit, and then load the corresponding driver, thereby realizing adaptive loading of the Boost control circuit driver.

The present disclosure will be described in detail below in conjunction with application examples.

This embodiment provides a SLIC Boost control circuit adaptive software solution design. In certain implementation schemes, see Figure 5, which is a principle block diagram of the SLIC Boost control circuit adaptive software solution. According to the block diagram shown in Figure 5, this embodiment sets a SLIC simple driver on the host AP side to allow the SLIC PWM pin to output a 100ms high level to the Boost control circuit. Since the PNP Boost solution is turned on at a low level, and the NMOS Boost solution requires a high level to be turned on, when the SLIC PWM pin outputs a high level, the Isen of the NMOS Boost solution has a detection current, and the Isen of the PNP Boost solution has no current. Since the high level lasts for a very short time, it will not cause damage to the transistor. At this time, the host reads the SLIC register data about Isen through SPI to determine whether there is current. If there is current in Isen, reload the driver of the NMOS solution. If there is no current in Isen, retest and load the driver of the PNP solution.

In certain embodiments, see FIG6 , which is a flow chart of the SLIC Boost control circuit adaptive software operation process. The process in this embodiment is as follows:

Step 601: Start;

Step 602: Load the SLIC simple driver (the SLIC MWM pin only outputs a high level for 100ms);

Step 603: The host AP reads the SLIC Isen register status via SPI;

Step 604: Isen whether there is current;

If there is no current, execute step 605; if there is current, execute step 606;

Step 605: The host reloads the PNP Boost driver;

Step 606: The host reloads the NMOS Boot driver;

Step 607: End.

This embodiment sets a simple SLIC driver program, so that the PWM output pin of the SLIC only outputs a high level for 100ms, reads the Isen register through SPI, determines whether there is current, identifies whether the current is a PNP Boost solution or an NMOS Boost solution, and then loads the corresponding SLIC driver program to allow the SLIC to work normally. That is, this embodiment proposes a new SLIC Boost control circuit adaptive software design scheme, which sets a simple SLIC driver program, so that the PWM output pin of the SLIC only outputs a high level for 100ms, reads the Isen register through SPI, determines whether there is current, identifies whether the current is a PNP Boost solution or an NMOS Boost solution, and then loads the corresponding SLIC driver program to allow the SLIC to work normally. NMOS Boost solution, and then load the corresponding SLIC driver to make SLIC work normally, which can effectively avoid downloading the wrong SLIC program to burn out the Boost circuit transistors and cause it to not work.

In order to implement the method of the embodiment of the present disclosure, the embodiment of the present disclosure also provides a driver loading device. As shown in FIG. 7 , the driver loading device 700 includes: a control module 701, a reading module 702 and a loading module 703; wherein,

The control module 701 is configured to control the user line interface circuit to output a high level voltage to the Boost control circuit;

A reading module 702, configured to read the Isen register data in the subscriber line interface circuit; and

The loading module 703 is configured to load a driver corresponding to the Boost control circuit according to the Isen register data.

In the related art, in order to solve the problem of SLIC Boost control circuit adaptation, the method adopted is: by setting a dedicated detection IO in the SLIC circuit, manually configuring the IO to be high or low, allowing the host AP to detect the high and low levels of the IO, and judging whether the boost circuit scheme of the SLIC circuit is a triode scheme or a MOS tube scheme, and then loading the corresponding driver.

This method requires identifying the high and low levels of the manually set detection IO, and there may be a situation where an error is uploaded, or there may be a situation where the external detection IO is not set, resulting in the inability of the compatible driver to function.

Based on this, this embodiment provides a SLIC Boost control circuit adaptive method, which does not require an additional external detection circuit. It uses the characteristics of the conduction levels of the two boost circuit transistors to detect the presence or absence of feedback current, judge the SLIC Boost control circuit solution, and then load the corresponding SLIC driver to avoid downloading the wrong driver, which may cause the Boost control circuit transistor to burn out.

In some embodiments, the SLIC external boost circuit in this embodiment includes a PNP Boost control circuit and an NMOS Boost control circuit, as shown in FIG3 and FIG4 respectively. In some embodiments, the loading of a driver corresponding to the Boost control circuit according to the Isen register data includes: judging whether Isen has current according to the Isen register data; and loading the NMOS Boost control circuit when the Isen has current. The driver corresponding to the control circuit; when there is no current in the Isen, the driver corresponding to the PNP Boost control circuit is loaded.

In certain implementation schemes, when controlling the subscriber line interface circuit to output a high level voltage to the Boost control circuit, the PWM pin of the subscriber line interface circuit may be controlled to output a high level voltage to the Boost control circuit.

In some embodiments, in order not to damage the transistor, the user line interface circuit can be controlled to output a high level voltage to the Boost control circuit within a first duration. The first duration can be set based on the situation. Specifically, when setting, the first duration should be set to a smaller value, so that the duration of outputting the high level voltage to the Boost control circuit is shorter, thereby not damaging the transistor.
