The system further comprises an online router access module (also called as A machine access module), a standby router access module (also called as B machine access module), an external line access module, a management module and a circuit switching module.
As shown in fig. 1 to 5, the online router access module is used to connect access for each asynchronous interface of a router running online; the standby router access module is used for accessing each asynchronous interface of the standby router; the external connection module is used for linking the local MODEM equipment.
As shown in fig. 1 to 5, the management module detects an operation state of the online router, activates and deactivates an alarm function, switches a mode selection, and manually switches.
As shown in fig. 1 to fig. 5, the management module firstly collects a large number of data transmission signals under the condition that the router normally operates through experiments, obtains the minimum number per unit time of the asynchronous port data transmission signals (TxD), i.e. the minimum limit value, of the asynchronous port data transmission signals under the condition that the router normally operates, and if the data transmission signals (TxD) collected by the switcher at the same time period to all the ports of the router are lower than the limit value through comparison, it can be determined that the router operating on line is in a fault state. Or the number of the data transmission signals of one or more asynchronous ports of the router is lower than the limit value for a long time, the ports and related circuits of the router can be judged to have faults.
The alarm function and alarm releasing function of the management module are realized in the following modes:
when the management module detects that the running state of the online router is abnormal, the buzzer is driven to sound through the driving circuit so as to remind an operator to observe the running state of the router, and further judgment is made so as to determine whether to switch. The operator can also press the reset key to remove the alarm.
The switching mode selection of the management module is such that:
the device provides two switching modes: firstly, manual switching is carried out; second, intelligent switching. If manual switching is selected, when the switcher detects that the running state of the router is abnormal, the buzzer is driven to alarm, an operator is reminded to observe the running state of the router, and whether manual switching is performed or not is judged; if intelligent switching is selected, under the unattended condition, once the router running state abnormality is detected by the switcher, the management module drives the switching module to switch by itself.
The switching function of the circuit switching module is realized as follows: the circuit switching is realized by a plurality of miniature electromagnetic relay elements because the electromagnetic relay is generally composed of an iron core, a coil, an armature, a contact reed, and the like. As long as a certain voltage is applied to the two ends of the coil, a certain current flows in the coil, so that an electromagnetic effect is generated, the magnet overcomes the pulling force of the return spring and is attracted to the iron core under the attraction effect of the electromagnetic force, and the movable contact and the fixed contact of the armature are driven to be attracted. When the coil is powered off, the electromagnetic attraction disappears, and the armature returns to the original position under the pushing of the counterforce of the spring, so that the movable contact and the original fixed contact are attracted. The circuit is switched by the pull-in and release.
The utility model relates to a network information center router auto-change over device, its circuit part includes: the system comprises an online router access module, a standby router access module, an external line access module, a management module and a circuit switching module.
The online router access module is used for connecting access of each asynchronous interface of a router which is running online; the standby router access module is used for accessing each asynchronous interface of the standby router; the outside connection module is used for linking the local MODEM device, as shown in fig. 1.
The management module has the following functions: firstly, detecting the running state of an online router; secondly, starting and relieving the alarm function; thirdly, a switching mode selection function; fourthly, switching function; as shown in fig. 2.

Or the number of the data transmission signals of one or more asynchronous ports of the router is lower than the limit value for a long time, the ports and related circuits of the router can be judged to have faults.
The alarm function and alarm releasing function of the management module are realized in the following modes:
when the management module detects that the running state of the online router is abnormal, the buzzer is driven to sound through the driving circuit so as to remind an operator to observe the running state of the router, and further judgment is made so as to determine whether to switch. The operator can also press the reset key to remove the alarm.
The switching mode selection of the management module is such that:
the device provides two switching modes: firstly, manual switching is carried out; second, intelligent switching. If manual switching is selected, when the switcher detects that the running state of the router is abnormal, the buzzer is driven to alarm, an operator is reminded to observe the running state of the router, and whether manual switching is performed or not is judged; if intelligent switching is selected, under the unattended condition, once the router running state abnormality is detected by the switcher, the management module drives the switching module to switch by itself.

the circuit switching is realized by controlling a plurality of miniature electromagnetic relay elements through a microprocessor in the management module, because the electromagnetic relay generally comprises an iron core, a coil, an armature, a contact reed and the like. As long as a certain voltage is applied to the two ends of the coil, a certain current flows in the coil, so that an electromagnetic effect is generated, the magnet overcomes the pulling force of the return spring and is attracted to the iron core under the attraction effect of the electromagnetic force, and the movable contact and the fixed contact of the armature are driven to be attracted. When the coil is powered off, the electromagnetic attraction disappears, and the armature returns to the original position under the pushing of the counterforce of the spring, so that the movable contact and the original fixed contact are attracted.
