Summary of the invention
The purpose of this utility model is to overcome the problem that can't return to operating state after ADSL MODEM goes offline, crashes in working online in the prior art, provide a kind of can be from go offline, crash self-healing control device.
For realizing above purpose, the utility model has been taked following technical scheme: a kind of Asymmetric Digital Subscriber Line modem system, comprise the ADSL MODEM, the CPU application terminal that are electrically connected successively, be electrically connected with control switch between described ADSLMODEM and CPU application terminal, described ADSL MODEM is electrically connected with power supply by control switch; In this CPU application terminal, be provided with the main control unit that receives the mutual handshake of local side administrative center; Described main control unit detects terminal cpu and has or not the handshake of receiving that local side administrative center sends, controls described control switch according to this testing result.
Operation principle of the present utility model: the application terminal that contains CPU adopts the terminal management center of ADSL mode and local side to carry out exchanges data, upload data, and carry out shaking hands alternately regularly with administrative center, if the CPU application terminal can not receive the handshake of administrative center and carries out handshake request and affirmation, when confirming that ADSL MODEM occurs can't carrying out transfer of data unusually, restart and dialing online again after then cutting ADSL MODEM power supply certain hour.
Described main control unit includes the interactive unit of shaking hands, and receives the handshake of described local side administrative center and sends answer signal to local side administrative center; Detecting unit, being used to detect the described interactive unit of shaking hands has or not and receives the confirmation signal of shaking hands that described local side administrative center sends, when detecting the interactive unit of shaking hands and not receiving described handshake, it sends control signal, and described control switch is connected according to this control signal deenergization and ADSL MODEM's.
Described main control unit also includes first delay unit of setting monitoring period, this first delay unit is electrically connected with the described interactive unit of shaking hands, and the described interactive unit of shaking hands is sent request signal to described local side administrative center in the monitoring period that first delay unit is set.
Described main control unit also includes the limit transfer slip unit that sets the continuous monitoring number of times, and this limit transfer slip unit is electrically connected with the described interactive unit of shaking hands, and the interactive unit of shaking hands is sent request signal to described local side administrative center repeatedly in the monitoring number of times of limitting the first setting of transfer slip.
Also include second delay unit, described detecting unit detects the interactive unit of shaking hands and fail to receive the confirmation signal of shaking hands of local side administrative center in the monitoring number of times that limit transfer slip unit sets, and then the monitoring period of setting according to second delay unit is controlled described control switch and opened and closed being connected of ADSL MODEM and power supply.
The CPU application terminal is by MODEM and platform communication, as not receiving shaking hands of local side administrative center within the time of setting at first delay unit, think that then MODEM has the possibility that goes offline, crashes, therefore the power supply of MODEM is closed in the CPU application terminal by control switch, after the time that first delay unit is set, control switch is opened the MODEM power supply again.Simultaneously after the number of times that limit transfer slip unit sets, as the time lengthening of still failing and the contact of local side administrative center, then opening to close the MODEM power supply in the time that second delay unit is set, to avoid MODEM power-on and power-off repeatedly, the useful life of protection MODEM.
Described control switch is electrically connected with I/O interface on being arranged on the CPU application terminal.Control switch is controlled by the level of I/O output on the CPU application terminal, gives the power supply of ADSL MODEM power supply and cut-off switch cut-out ADSL MODEM with Closing Switch;
The utility model compared with prior art has following advantage: solved effectively by the control of handshake request/confirmation signal and electric power on/off that ADSL MODEM long-play goes offline, the deadlock problem, and transfer of data is carried out in the operation that recovers ADSLMODEM; Support ADSL broadband access product can be under need not the situation of human intervention operate as normal, there is fault to detect and recovery automatically, improved the stability of ADSL broadband access, satisfy the ADSL broadband access and extend the requirement of the industrial application of information technology, widened the range of application of ADSL broadband access the long-term stability operation.
