Signal input module mainly is to realize the input of normal signals such as the input of door magnetic signal, the input of shift knob signal, the input of TTL auxiliary signal, the input of door lock state signal; Signal output module mainly is to realize door lock signal output, the output of door lock state signal, the output of normal signals such as electric lock power supply introducing signal output.
This programme only needs just can realize real ring bus networking to many communication interface chips of access controller interpolation and peripheral circuit (connection terminal); Increase from the angle of cost and not to be a lot, but product stability and maintainability are increased greatly.
A kind of annular door access control system also is provided in the utility model; This system comprises the webserver and at least one group of aforesaid access controller; Every group comprises N access controller, and wherein N >=2 are provided with two host computer interfaces on each access controller; Adopt the N-1 communication bus to interconnect between the access controller in same group, the host computer interface that does not connect on two access controllers of wherein same group initial and end is connected with the webserver respectively.
The webserver and access controller all adopt the mechanism of concurrent communication in this gate control system.
Two slave computer communication interfaces of every group of access controller map network server.
Be on access controller, also to indicate corresponding numbers in the preferable scheme.
All be to adopt the transmission protocol mode to communicate between the said webserver and the access controller, between the access controller.
The advantage of this gate control system is:
1, when the circuit generation disconnection in the ring bus, this chip one section telecommunication circuit of living in was lost efficacy, whole system still can continue communication through 2 end buses, can not impact whole system.After comparing old ring bus disconnection, only have a circuit effective, reliability increases a lot.
2, during situation, this chip one section telecommunication circuit of living in was lost efficacy to ground when ab line short circuit or line short circuit take place the circuit in the ring bus, whole system still can continue communication through 2 end buses, can not impact whole system.
3, if after line short or disconnection occurring, network server can be judged between certain two circuit and break down, and brings very large convenience to maintenance like this.Therefore native system has better practicability and market outlook.
