(8), after the target silicone tube has been installed wireless intelligent silicone tube stopper; System failure monitoring modular in the wireless intelligent silicone tube stopper begins to start automatically and operation constantly; Be installed in the range sensor of silicone tube on the plate as monitoring 2 groups of silicone tubes when the distance between the plate does not reach the control of conduction and cut-off target silicone tube; With feedback information to linear electric motor control module, restart control program in real time, carry out feedback control; To reach the control effect, avoid the generation of the system failure; In addition; Alarm module will be triggered; The LED warning light is started working with alert ring, the external storage in the system failure monitoring modular simultaneously the opening entry fault message to guarantee in the very first time detection failure, record trouble, analysis of failure, reparation fault and Access Control System in order to the adjustment fault;
(9), when the standby power supply in the system failure monitoring modular will externally power module be stopped power supply, standby power supply starts voluntarily, the control of assurance device;
(10), linear electric motor control module, wireless signal transmission module, linear electric motor Executive Module and the system failure monitor between four parts and communicate with universal serial bus mode and wireless signal transmitting-receiving, constitutes a communications network system.
