When being embodied as, infrared sensor is at least 4, keeps the distance effect of 30 centimetres to 50 centimetres preferably between two adjacent sensors.
First embodiment is to install 4 infrared sensors, and the distance between adjacent sensor is 40 centimetres, and the distance between first sensor to the 4th sensor is 120 centimetres. First sensor is in storehouse door the inside, and the 4th (last) sensor is at storehouse door outermost. Namely the distance between last infrared sensor and first infrared sensor to meet the space restriction of storehouse, warehouse door, and less than the length of target object.
Timing acquisition object goes out to block when putting in storage the signal that blocks of infrared sensor situation, forms one and blocks sequence. Block sequence from having one or more infrared sensor to be blocked, until all infrared sensors are all without being blocked.
Owing to large-sized object is when going out to put in storage, translational speed is maximum reaches 5 meter per seconds, according to the distance between adjacent infrared sensor 40 centimetres, it is possible to calculate object by the time that 40 cm distance need be 0.4/5=0.08 second=80 milliseconds. Therefore, processing device should every less than 80 milliseconds (such as, 50 milliseconds), the inquiry situation that once whether each infrared sensor is blocked. Often inquire about once, one can be obtained and block signal, for instance: (sensor 1 is blocked), (sensor 1 is blocked, sensor 2 is blocked), (sensor 1 is blocked, sensor 2 is blocked, sensor 3 is blocked), (sensor 1 is blocked, sensor 3 is blocked) etc. These block signal can be abbreviated as (1), (12), (123), (13) respectively.
When process device inquire block signal designation have infrared sensor to be blocked time, begin to a storage blocking sequence, every 50 milliseconds of inquiries once, if to block signal with last time identical for this signal that blocks inquired, then this blocks signal and does not just store and block in sequence. When process device inquire block signal designation do not have infrared sensor to be blocked time, just terminate one and block sequence, following steps judge.
For 4 infrared sensors, a possible sequence of blocking is: (2), (1), (12), (123), (23), (1234), (34), (234), (34), (4), (3). The first of normal outbound blocks sequence: (1), (12), (123), (1234), (234), (34), (4). The second of normal storage blocks sequence: (4), (34), (234), (1234), (123), (12), (1).

(4) if reverse search original position is k, then from blocking sequence (k-1) individual position, to blocking first position of sequence, find and block signal (1). Without finding, then terminate reverse search; If blocking m-th in sequence to block signal for (1), then F adds 1, and terminates reverse search;
(5) if forward lookup original position is i, then from blocking sequence (i+1) individual position, to blocking last position of sequence, find and block signal (234). Without finding, then labelling forward lookup original position r=i; If blocking the individual signal that blocks of r in sequence for (234), then F adds 1, and labelling forward lookup position is r;
(6) if forward lookup original position is r, then from blocking sequence (r+1) individual position, to blocking last position of sequence, find and block signal (34). Without finding, then labelling forward lookup original position s=r; If blocking the individual signal that blocks of s in sequence for (34), then F adds 1, and labelling forward lookup position is s;
(7) if forward lookup original position is s, then from sequence (s+1) individual position, to last position of sequence, find and block signal (4). Without finding, then terminate forward lookup; If blocking the individual signal that blocks of t in sequence for (4), then F adds 1, and terminates forward lookup.
(8) if blocking and sequence occurring multiple block signal (1234), then each signal (1234) that blocks is calculated its outbound signal-count F, select maximum outbound signal-count F as last outbound signal-count F.

To install 5 infrared sensors for the second embodiment, the distance between adjacent sensor is 40 centimetres, and the distance between first sensor to the 5th sensor is 160 centimetres. First sensor is in storehouse door the inside, and the 5th (last) sensor is at storehouse door outermost. Namely the distance between last infrared sensor and first infrared sensor to meet the space restriction of storehouse, warehouse door, but less than the length of target object.
Timing acquisition object goes out to block when putting in storage the signal that blocks of infrared sensor situation, forms one and blocks sequence. Block sequence from having one or more infrared sensor to be blocked, until all infrared sensors are all without being blocked.
Owing to large-sized object is when going out to put in storage, translational speed is maximum reaches 5 meter per seconds, according to the distance between adjacent infrared sensor 40 centimetres, it is possible to calculate object by the time that 40 cm distance need be 0.4/5=0.08 second=80 milliseconds.Therefore, processing device should every less than 80 milliseconds (such as, 50 milliseconds), the inquiry situation that once whether each infrared sensor is blocked. Often inquire about once, it is possible to obtain one and block signal.
When process device inquire block signal designation have infrared sensor to be blocked time, begin to a storage blocking sequence, every 50 milliseconds of inquiries once, if to block signal with last time identical for this signal that blocks inquired, then this blocks signal and does not just store and block in sequence. When process device inquire block signal designation do not have infrared sensor to be blocked time, just terminate one and block sequence, following steps judge.
