Fig. 1 is the electrical schematic diagram of the utility model embodiment.

Embodiment

With reference to Fig. 1, the utility model is made up of triode Q1, Q2, diode D1, light lotus root pipe OP1, OP2, K switch 1 to K3, resistance R 1 to R1O, wire-pressed terminal S1 to S6.Fig. 1 is the electrical schematic diagram of present embodiment, and embodiment presses Fig. 1 connection line.Fig. 1 middle connecting terminal S1 is connected with enabling signal, as the enabling signal of circuit.Connection terminal S2 is connected with upper end module connecting line.Connection terminal S3 is connected with lower end module connecting line.Connection terminal S5 is connected with local synchronous signal, imports the synchronizing signal that this module produces.Connection terminal S6 is connected with synchronous bus, is all module common transmitted synchronizing signals in the yarn system.Connection terminal S4 is K switch 3 signal input end.

The concise and to the point work of the utility model is as follows:

At first the regulation module that is arranged in system's least significant end is No. 1 module, is followed successively by from bottom to top No. 2, No. 3 ... the upper end module, the K1 closure of No. 1 module, the K2 of other modules disconnects.During No. 1 module work, the S1 enabling signal is a high level, light lotus root pipe OP1 conducting, the current collection of OP1 is low level very, triode Q1 conducting, and the anode of light lotus root pipe OP2 is a high level, negative electrode is owing to K switch 1 closure is passed through R5 ground connection, light lotus root pipe OP2 conducting, the current collection of OP2 is low level very, triode Q2 conducting, the signal of connection terminal S4 is a high level, make electronic switch K3 conducting, the synchronizing signal of this machine S5 and S6 synchronous bus are connected, and become primary module.Because the triode Q1 of No. 1 module is in conducting state, the current collection of Q1 is high level very, the negative electrode of the light lotus root pipe OP2 of all upper end modules of No. 1 module is a high level, so the light lotus root pipe OP2 of all upper end modules of No. 1 module all is in cut-off state, so, the Q2 of all modules is in cut-off state, and the signal of connection terminal S4 is a low level, the electronic switch K3 of all modules all disconnects, and this machine S5 synchronizing signal can not link to each other with the S6 synchronous bus.

When No. 1 module because failure cause when out of service, the S1 enabling signal becomes low level, light lotus root pipe OP1 ends, triode Q1 ends, the collector of Q1 becomes low level, and the negative electrode of the light lotus root pipe OP2 of No. 2 modules that at this moment are attached thereto is a low level, the OP2 conducting of No. 2 modules, its triode Q2 conducting immediately, connection terminal S4 signal becomes high level by low level, and the synchronizing signal of No. 2 this machine of module S5 and S6 synchronous bus are connected, and become primary module.And the like, when breaking down, No. 2 modules withdraw from, No. 3 module becomes primary module ... therefore it has abandoned the single-point bottleneck of single signal source, there are a plurality of signal sources in the system, when the signal source as the low side primary module withdraws from, from remaining module, produce primary module again, and with the signal source of its signal source, thereby the normal operation of the system of assurance as system.
