A seal character recognition method comprises the steps of using the seal character recognition device to recognize a seal, comprising an instruction system, and the recognition method comprises the following steps:
the method comprises the following steps: the instruction system sends an advancing driving instruction to the driving component, and the driving component drives the cargo way belt 104 to advance towards the direction of the stock sensor 102, so that the cargo way belt 104 carries the seal to move to the extreme edge of the identification end of the cargo way, and the seal enters the sensing area and the identification area of the stock sensor 102;
step two: the stock sensor 102 senses the seal and feeds back the seal to the instruction system, the instruction system sends a backward movement driving instruction to the driving assembly, the driving assembly drives the cargo way belt 104 to move backward, the cargo way belt 104 carries the seal to move backward, the seal leaves a sensing area of the stock sensor 102 and is located in an identification area, and the seal waits for identification;
step three: the stock sensor 102 feeds back the seal leaving the sensing area to the instruction system, the instruction system sends a forward movement driving instruction to the driving assembly, and the steps are repeated until the seals on all the cargo channels wait for identification;
step four: the instruction system sends a lifting instruction to the lifting module 2, the lifting module 2 drives the identification module 3 to lift to the corresponding goods way shelf 101, the instruction system sends an identification instruction to the identification module 3, and the identification probe 36 moves left and right along the direction of the lead screw 32 to identify the seal on the goods way.
In this embodiment, after the instruction system sends an advance driving instruction to the driving component, the lane motor 105 drives to drive the lane belt 104 to operate, so as to drive the seal to move towards the direction of the stock sensor 102, since the stock sensor 102 is arranged in front of the identification end of the lane, in order to ensure that the seal can enter the sensing area, the seal needs to move to the extreme edge of the identification end of the lane, and since the range of the identification area is greater than that of the sensing area, the seal inevitably enters the identification area after entering the sensing area;
after the seal is sensed by the stock sensor 102 again, the stock sensor 102 feeds back to the instruction system, after the instruction system receives the feedback, the instruction system sends a backward movement driving instruction to the driving component again, the cargo way motor 105 drives the cargo way belt 104 to operate, and drives the seal to move in a direction far away from the stock sensor 102, so that the seal leaves a sensing area of the stock sensor 102, but the seal does not leave an identification area;
because the stock sensor 102 is arranged in front of the identification end of the goods channel, when the seal enters the sensing area, the stock sensor is located at the edge of the goods channel, the identification module 3 is arranged in front of the goods-to-module 1, if the identification module 3 is started for identification at the moment, the lifting module 2 drives the identification module 3 to lift and the identification module 3 to transversely move along the lead screw 32, the stock sensor is easily knocked off by the identification probe 36, so that the seal falls off from the goods channel, the stock sensor 102 is arranged to drive the seal to move back again after sensing the seal, the identification probe 36 is prevented from being knocked off, and meanwhile, in order to ensure that the seal can be identified by the identification probe 36, when the seal moves back, the seal only needs to move to leave the sensing area, but cannot leave the sensing area.
After the stock sensor 102 senses that the sealing strips leave the sensing area, the feedback is carried out on the instruction system again, the instruction system sends forward movement driving instructions to the driving assembly, and the steps are repeated until the sealing strips on all the goods channels wait for identification;
then, the instruction system sends a lifting instruction to the lifting module 2, the lifting module 2 drives the identification module 3 to lift to the corresponding goods channel shelf 101, the instruction system sends an identification instruction to the identification module 3, and the identification probe 36 moves left and right along the direction of the lead screw 32 to identify the seal on the goods channel;
furthermore, in order to reduce the cost, in this embodiment, only two stock sensors 102 are arranged on each layer of lane shelf 101 and are respectively located on the support pillars 100 at both sides, so that only one lane seal enters the sensing area and can be identified by the stock sensors 102, and therefore, in this embodiment, the one lane seal needs to enter the sensing area and then leave the sensing area again, stay in the identification area to wait for identification, and the other lane seal can move; if the sealing strips of a plurality of goods channels move simultaneously, the stock sensor 102 can only identify the existence of the sealing strips, but the upper sealing strip of which goods channel can not be accurately positioned enters the sensing area, so that the instruction system can not send an instruction of accurate positioning identification to the identification module 3.
In the prior art, the stock sensors 102 are disposed at two sides of the cargo way, but not disposed in front of the cargo way, and there are the following problems: because the edge of the goods way is based on the principle of the sensing area, after the seal moves to the sensing area, the user does not need to worry that the identification probe 36 can knock over the seal, so the seal does not need to retreat, but the seal stays in the sensing area all the time and is sensed by the stock sensor 102, the condition that the seals on other goods ways can not move can not be met, if the seals of other goods ways still move continuously under the condition that the seal of a certain goods way is sensed by the stock sensor 102 continuously, the problem that the stock sensor 102 in the upper part can not accurately position the upper seal of the goods way to enter the sensing area, and further the command system can not send a command of accurate positioning and identification to the identification module 3 can occur, if the seal exits the sensing area after entering the sensing area, the problem can be solved, but at this moment, the stock sensors 102 are arranged at two sides of the goods way, the seal strip continues to retreat, and then the seal strip can be led to exit from the identification area of the identification probe 36, and the seal strip can not be identified, so that in conclusion, the stock sensor 102 is arranged at two sides in front of the goods channel, and the seal strip is retreated out of the induction area again after entering the induction area and stays in the identification area, so that the effect of identifying the seal strip can be perfectly realized under the condition of accurately positioning the goods channel number of the seal strip to be identified.
Preferably, the lifting instruction includes the number of layers of the goods passage shelf 101;
the identification instruction includes a number of lanes.
Further, in this embodiment, since each layer of goods way shelves 101 is provided with a stock sensor 102, the instruction system can generate a lifting instruction containing the number of layers of the corresponding goods way shelves 101 by determining which layer of stock sensor 102 sends a signal;
further, in this embodiment, according to the text identification method for a seal of the present invention, it can be known that the sensing requirement of the seal is satisfied after the sensing of one lane is completed, and then the sensing of the other lane is performed, so through this step, the stock sensor 102 can accurately know on which lane the seal to be identified is located, and the command system can generate the identification command containing the number of the corresponding lanes.
The technical principle of the present invention is described above in connection with specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without inventive effort, which would fall within the scope of the present invention.
