In addition, first parts in above-described embodiment are movable part, second parts are first sense switch, the 3rd parts are second sense switch, and this first sense switch and second sense switch are installed on the two ends up and down of gathering sill, but be not limited to this, a projection, then second parts can respectively be installed in the two ends up and down of gathering sill, the 3rd parts are projection, and a sense switch is installed on first parts (being movable part), when movable part is touched second parts, sense switch closure on the movable part is exported first signal of telecommunication to control module, when movable part is touched the 3rd parts, sense switch closure on the movable part is exported second signal of telecommunication to control module.
Describe the control method that the invention safe and intelligent is locked in detail below in conjunction with Fig. 1 to Fig. 5, specifically comprise the steps:
S1: communication interface 132 receive outside send execute sealed signal processed, and will execute the envelope signal and be sent to control module 131;
S2: control module 131 detects first sense switch 1341, whether second sense switch 1342 and the 3rd sense switch 1343 satisfy is executed strip of paper used for sealing spare, if satisfy, (be that movable part 15 is not touched first sense switch 1341 and second sense switch 1342, the 3rd sense switch 1343 is closure state, locking bar 12 and shell 19 is closed and intact) then export one and control signal to control motor 133, control motor 133 starts, and drive corresponding execution unit and carry out and execute the envelope action, execute seal successfully after, output one controls signal to control motor 133, and control motor 133 stops the rotation, and returns by communication interface 132 and to execute the envelope successful result, otherwise, return and execute the envelope failure result;
S3: execute and be honored as a queen, control module 131 detects first sense switch 1341 in real time, whether normally (namely whether first sense switch 1341 and second sense switch 1342 be touched for second sense switch 1342 and the 3rd sense switch 1343, whether the 3rd sense switch 1343 disconnects), if alert takes place, and (namely first sense switch 1341 or second sense switch 1342 are touched, or the 3rd sense switch 1343 disconnections), corresponding sense switch is exported an alarm signal to control module 131, control module 131 is preserved this alarm signal, and sends alarm signal to the external world by communication interface 132;
S4: communication interface 132 receives the outside deblocking control signal that sends, and the deblocking signal is sent to control module 131;
S5: control module 131 detects first sense switch 1341, the current state of second sense switch 1342 and the 3rd sense switch 1343, and the alarm signal of preserving according to history and current detection state carry out the judgement before the deblocking, (namely first sense switch 1341 and second sense switch 1342 are in off-state if satisfy the deblocking condition, the 3rd sense switch 1343 is in closure state, and alarm is disengaged), then export one and control signal to control motor 133, control motor 133 starts, and drive corresponding execution unit and carry out the deblocking action, after the deblocking success, output one controls signal to control motor 133, control motor 133 stops the rotation, and return the deblocking successful result by communication interface 132, otherwise, the deblocking failure result returned.
Seal in the step above-mentioned executing, control module 131 can judge whether successful execute envelope operates according to executing envelope sense switch 1344.
In above-mentioned deblocking step, control module 131 can judge whether unsealing operation is successful according to first sense switch 1341.
In above-mentioned deblocking step, if alarm took place before deblocking, then must sound all clear earlier and could carry out unsealing operation.
Safe and intelligent of the present utility model is locked to has following advantage less.
1, safe and intelligent lock of the present utility model is realized alarm detection and status detection function by movable part, first sense switch and second sense switch are set, the detecting unit of locking bar separates with locking bar, transmit signal by simple mechanical device (movable part) between the two, make that this safe and intelligent lock construction is simple, the signal transmission is stable.
2, because an end of connecting line links to each other with roating sphere free to rotate, so locking bar can freely rotate with respect to lock body and not be subjected to the restriction of rotational angle.
3, break down or after locking bar cut off when the electronic control system of safe and intelligent lock, can directly change electronic control system or locking bar and need not reconnect the circuit line, convenience easy to maintenance.
The above only is preferable possible embodiments of the present utility model, and unrestricted protection domain of the present utility model.Every equivalent structure or equivalent flow process conversion that utilizes the utility model manual and accompanying drawing content to do, or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
