Preferably, the control main frame also includes warning circuit, and the warning circuit is communicated with cell monitoring center.
The beneficial effect of the cell security access control system based on two-wire system that the present invention is provided is：Only using both threads it is
Simply, there is interference problem and can notify maintenance side in time in low cost for the transmission of achievable multiple signals, design and wiring.
Description of the drawings：
Fig. 1 is the schematic diagram of the cell security access control system based on two-wire system provided by the present invention.
Wherein reference 1- doorway machine；2- indoor terminals；3- control main frames.
Specific embodiment：
The present invention is described further in conjunction with accompanying drawing.
As Fig. 1 shows the schematic diagram of the cell security access control system based on two-wire system provided by the present invention.A kind of base
In the cell security access control system of two-wire system, including doorway machine 1, control main frame 3 and indoor terminal 2, wherein, doorway machine 1 passes through
Both threads connect control main frame 3, and control main frame 3 connects all indoor terminals 2 by both threads, doorway machine 1, control main frame 3 with
And between indoor terminal 2 by both threads come realize communication；The doorway machine 1 includes the first speech processing circuit, input unit
With unlocking circuit；The indoor terminal 2 includes the second speech processing circuit and tripper.
Preferably, the indoor terminal 2 also includes that storage includes audio signal, regards in self-checking circuit, the self-checking circuit
The standard self-test signal of frequency signal and control signal；At ordinary times, the control main frame 3 is closed and the company between all indoor terminals 2
Connect；When someone calls certain indoor terminal 2 by the input unit of the doorway machine 1, the control main frame 3 connects the interior
Terminal 2, then the self-checking circuit of the indoor terminal 2 standard self-test signal Jing control main frames 3 are sent to into the doorway machine 1, institute
The self-checking circuit that the standard self-test signal Jing control main frames 3 for receiving are fed back to doorway machine 1 indoor terminal 2 again is stated, it is described
The standard self-test signal that the standard self-test signal for feeding back to is sent with which is compared by self-checking circuit, if in allowed band,
Then start normal work, the both threads simultaneous transmission electric power signal, audio signal, vision signal and control signal；If exceeding
