A kind of terminal equipment theory diagram that Fig. 1 provides for the embodiment of the invention;
The method flow diagram of a kind of terminal equipment power failure alarm reporting that Fig. 2 provides for the embodiment of the invention.
Embodiment
In conjunction with the accompanying drawings the present invention is described in further detail below by embodiment.
As shown in Figure 1, be example with the PON terminal equipment, the main functional modules of PON terminal equipment comprises PON protocol processes functional module, PON optical module and user function module.Wherein:
PON protocol processes functional module is finished the mutual conversion of user data package and PON protocol massages.
The PON optical module is finished the mutual conversion of the light signal and the signal of telecommunication.
The user function module provides service interface to the user, and user function module commonly used comprises: Ethernet switched circuit and ethernet physical layer circuit, its function are to provide the Ethernet data service to the user; Plain old telephone interface circuit, its function are to provide the phone access service to the user; USB circuit, its function are to provide the USB interface service to the user; WLAN (wireless local area network) circuit, its function are to provide the WLAN (wireless local area network) access service to the user; Coaxial cable TV signal circuit, its function are to provide the cable TV access service to the user.These several classes are user function modules more common and commonly used, but are not limited to this several user function modules.Need to prove that Ethernet switched circuit, ethernet physical layer circuit, plain old telephone interface circuit, WLAN (wireless local area network) circuit etc. have the RESET input; USB line feed part, coaxial cable TV signal circuit does not have the RESET input.
PON terminal equipment, especially domestic type terminal equipment adopt the 12V power voltage supply of standard code.Device interior is converted to 12V low-voltages such as 3.3V, 1.8V, 1.2V by voltage changer, for each functional module work in the terminal equipment.
As shown in Figure 2, the method for PON terminal equipment power failure alarm reporting specifically may further comprise the steps:
After the step S201:PON terminal operate as normal, voltage detecting circuit compares input voltage (being generally 12V) and preset reference voltage, if input voltage is higher than preset reference voltage, the PON terminal equipment keeps normal operating state; When the user was closed electricity or grid power blackout, input voltage began to fall.When input voltage is lower than preset reference voltage, enter step S202.
Step S202: power module transmits control signal and stops the work of user function module to save the consumption to electric energy to the user function module.Concrete, if this user function circuit has the RESET input, then enter step S203; If this user function circuit does not have the RESET input, then enter step S204.
Step S203: this user function circuit that resets, it is quit work, reduce the power of its consumption greatly.
Step S204: cut off its working power input, make the power of its consumption be reduced to zero.
Step S205: to the power fail warning module, be PON protocol processes chip in the present embodiment, send interrupt signal, make it enter interrupt handling routine immediately.This interrupt handling routine is responsible for making up the power fail warning packet, empties the data cached district of current transmission, and the power fail warning packet is write the data cached district of transmission.Wait for the arrival of the next sending time slots that local side apparatus distributes then.
Step S206: when next sending time slots arrives, power fail warning information is sent to local side apparatus by optical fiber.Repeat the power fail warning packet is write the data cached district of transmission, continue the arrival of the next sending time slots of wait local side apparatus distribution.
Step S207: repeating step S206 is until the thorough power down of equipment, and for guaranteeing that local side apparatus receives the power fail warning that this interrupting device sends reliably, the S204 step preferably repeats 3 times.
In sum, the invention provides the method for a kind of terminal equipment and power failure alarm reporting thereof, owing to do not need jumbo storage capacitor, can satisfy of the strict demand of domestic type PON terminal equipment, on such PON terminal, very wide application scenarios and practical value be arranged size and cost.Continuous lifting along with communication network operation maintenance and management expectancy, report power fail warning or may be required on the terminal equipment of other type, to realize, as digital local loop, cable modem etc., certain thought of the present invention and implementation method have more than and are confined to the PON terminal.
Above content be in conjunction with concrete execution mode to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
