Description

Technical Field

[0001] The present invention belongs to the technical field of medicine dispensing error correction software system and hardware technology, and specifically relates to an intelligent medicine dispensing error correction and review method, system and equipment. Background Art

[0002] At present, the vast majority of existing smart medicine machines on the market do not have an automatic review function and only use manual review. Even a small number of smart medicine machines with a review function only perform a simple review at the medicine outlet of the smart medicine machine. If a user purchases multiple boxes of medicines, they will be stacked at the medicine dispensing port. The accuracy of the review is not high. There is a lack of counting and checking when dispensing medicines. When medicines on the aisles stick together, it is easy to cause multiple injections. At the same time, when some aisles malfunction, the robot fails to clear the faulty medicine aisle, resulting in the inability to dispense medicines normally, which gives users a bad experience. Summary of the Invention

[0003] 1. Purpose of the invention

[0004] In response to the above technical problems, the present invention provides a smart drug dispensing error correction and review method, system and equipment to solve the technical problems mentioned in the background technology that the existing smart medicine machines have low review accuracy, no counting and checking, no real-time inventory of drug channel inventory, and the inability of the drug dispensing operation to tolerate faulty channels.

[0005] 2. Technical solution

[0006] In order to achieve the above object, the present invention provides a technical solution: a smart medication error correction and review method, comprising the following steps:

[0007] Step 1: When picking up medicine, the robot moves to the designated aisle;

[0008] Step 2: Use a high-definition camera to take pictures of the medicine in the designated channel and compare them with the pictures of the medicines to be picked up in the database for verification. If the image verification shows that it is not the medicine to be picked up, the robot transfers the cached medicine to the medicine outgoing warehouse, then returns to remove the incorrect medicine from the medicine channel and transfers it to the recycling warehouse;

[0009] Step 3: When the image review is correct, the robot's high-speed drug feeding mechanism will feed the drugs into the drug hopper. When the drugs fall into the drug hopper, the feeding sensor will count the drugs that fall into the hopper.

[0010] Step 4: The laser rangefinder will take inventory of the actual inventory before and after the medicine is delivered from the cargo channel. The actual number of medicines delivered is obtained by subtracting the inventory after the medicine is delivered from the inventory before the medicine is delivered. If the count finds that the number of medicines dropped into the medicine hopper is less than the number of medicines to be taken, the medicine will be delivered again. If the number of medicines dropped into the medicine hopper is greater than the number of medicines to be taken, all the medicines in the medicine hopper will be transferred to the recycling warehouse and the medicine will be delivered again.

[0011] Preferably, if the same channel fails to deliver medicines for a fixed number of consecutive times, the channel is marked as a faulty channel. The next time medicines are delivered, the faulty channel is filtered out and only medicines from normal channels are delivered.

[0012] The present invention provides a smart medication dispensing error correction and review system, which includes

[0013] Medicine feeding module: The robot moves the medicine to the designated aisle for subsequent retrieval;

[0014] Image review and processing module: Use a camera to take pictures of medicines in a designated aisle and compare them with the pictures of medicines to be picked up in the database;

[0015] Medicine counting module: When the image verification is correct, the robot will transfer the medicine to the medicine hopper. When the medicine falls into the medicine hopper, the feeding sensor will count the medicine that falls into the medicine hopper.

[0016] Laser ranging module: It will take inventory of the actual inventory before and after the medicine is delivered from the cargo channel, and subtract the inventory after the medicine is delivered from the inventory before the medicine is delivered to obtain the actual number of medicines delivered. If the count finds that the number of medicines dropped into the medicine hopper is less than the number of medicines to be taken, the medicine will be delivered again. If the number of medicines dropped into the medicine hopper is greater than the number of medicines to be taken, all the medicines in the medicine hopper will be transferred to the recycling warehouse and the medicine will be delivered again.

[0017] Preferably, in the image review processing module, if the image review finds that the drug is not the drug to be taken, the robot transfers the cached taken drug to the drug output warehouse, then comes back to take out the wrong drug on the drug path and transfers it to the recovery warehouse.

[0018] Preferably, if the same channel fails to deliver medicines for a fixed number of consecutive times, the channel is marked as a faulty channel. The next time medicines are delivered, the faulty channel is filtered out and only medicines from normal channels are delivered.

[0019] Preferably, in the laser ranging module, the measured distance difference is compared with the thickness of the medicine box entered in the database to calculate the current inventory. If the current medicine route is not enough to meet the medicine order, the total inventory of the remaining medicine routes is calculated to see whether it meets this order. If it cannot be met, the order is returned. If it meets the current order, you can start taking the medicine.

[0020] Preferably, the distance is measured again after the medicine is taken, and the correct amount of medicine is calculated based on the value. If too much is taken, the medicine in this medicine bucket is transferred to the recycling warehouse. If the amount of medicine taken is correct, it is transferred to the medicine taking port to complete the order.

[0021] The present invention provides an intelligent drug dispensing error correction and review device, which includes a high-speed drug feeding mechanism, a feeding induction sensor, a high-definition camera and a laser rangefinder. The high-definition camera is used to take pictures of drugs in a designated cargo channel and pictures of drugs to be picked up in a database for review. When the image review is correct, the robot in the high-speed feeding mechanism will feed the drugs into the medicine hopper. When the drugs fall into the medicine hopper, the feeding induction sensor will count the drugs that have fallen into the hopper.

[0022] Preferably, it also includes a full material detection grating, which is arranged at the bottom of the feed induction sensor and is used to detect medicines falling onto the medicine path.

[0023] Preferably, it also includes a transmission gear mechanism to drive the medicine to move to the designated channel

[0035] Example 1

[0036] This embodiment provides a smart medication dispensing error correction and review method, including the following steps:

[0037] Step 1: When picking up medicine, the robot moves to the designated aisle;

[0038] Step 2: Use a high-definition camera to take pictures of the medicine in the designated channel and compare them with the pictures of the medicines to be picked up in the database for verification. If the image verification shows that it is not the medicine to be picked up, the robot transfers the cached medicine to the medicine outgoing warehouse, then returns to remove the incorrect medicine from the medicine channel and transfers it to the recycling warehouse;

[0039] Step 3: When the image review is correct, the robot's high-speed drug feeding mechanism will feed the drugs into the drug hopper. When the drugs fall into the drug hopper, the feeding sensor will count the drugs that fall into the hopper.

[0040] Step 4: The laser rangefinder will take inventory of the actual inventory before and after the medicine is delivered from the cargo channel. The actual number of medicines delivered is obtained by subtracting the inventory after the medicine is delivered from the inventory before the medicine is delivered. If the count finds that the number of medicines dropped into the medicine hopper is less than the number of medicines to be taken, the medicine will be delivered again. If the number of medicines dropped into the medicine hopper is greater than the number of medicines to be taken, all the medicines in the medicine hopper will be transferred to the recycling warehouse and the medicine will be delivered again.

[0041] Among them, if the same cargo channel fails to deliver medicines for a fixed number of consecutive times, the cargo channel will be marked as a faulty cargo channel. The next time medicines are delivered, the faulty cargo channel will be filtered out and only medicines from normal cargo channels will be delivered.

[0042] Example 2

[0043] Focus on reference Figure 1 This embodiment provides a smart medication dispensing error correction and review system, which includes

[0044] Medicine feeding module: The robot moves the medicine to the designated aisle for subsequent retrieval;

[0045] Image review and processing module: Use a camera to take pictures of medicines in a designated aisle and compare them with the pictures of medicines to be picked up in the database;

[0046] Medicine counting module: When the image verification is correct, the robot will transfer the medicine to the medicine hopper. When the medicine falls into the medicine hopper, the feeding sensor will count the medicine that falls into the medicine hopper.

[0047] Laser ranging module: It will take inventory of the actual inventory before and after the medicine is delivered from the cargo channel, and subtract the inventory after the medicine is delivered from the inventory before the medicine is delivered to obtain the actual number of medicines delivered. If the count finds that the number of medicines dropped into the medicine hopper is less than the number of medicines to be taken, the medicine will be delivered again. If the number of medicines dropped into the medicine hopper is greater than the number of medicines to be taken, all the medicines in the medicine hopper will be transferred to the recycling warehouse and the medicine will be delivered again.

[0048] In a preferred embodiment, in the image review processing module, if the image review finds that the drug is not the drug to be taken, the robot transfers the cached taken drug to the drug output warehouse, then comes back to take out the wrong drug on the drug path and transfers it to the recycling warehouse.

[0049] In a preferred embodiment, if the same channel fails to deliver medicines for a fixed number of consecutive times, the channel is marked as a faulty channel. The next time medicines are delivered, the faulty channel is filtered out and only medicines from normal channels are delivered.

[0050] In a preferred embodiment, in the laser ranging module, the measured distance difference is compared with the thickness of the medicine box entered in the database to calculate the current inventory. If the current medicine route is not enough to meet the medicine collection order, the total inventory of the remaining medicine routes is calculated to see whether it meets this order. If it cannot be met, the order is returned. If it meets the current order, you can start collecting medicine.

[0051] Among them, after the medicine is taken, the distance is measured again, and the number of medicines taken is calculated based on the value. If too much is taken, the medicine in this medicine bucket will be transferred to the recycling warehouse. If the number of medicines taken is correct, it will be transferred to the medicine taking port to complete this order (medicine taking review process).

[0052] Example 3

[0053] Focus on reference Figure 2This embodiment provides a smart medication dispensing error correction and review device. Before medication is dispensed, a high-definition camera 7 takes a picture of the medicine box and compares it with the database information to determine whether the medicine box is in the designated medicine lane. After the review is completed, laser rangefinder 1 5 and laser rangefinder 2 6 measure the distance between the two positions in the figure and calculate the difference. The difference is compared with the thickness of the medicine box entered into the system to calculate the current inventory. If the current medicine lane is insufficient to meet the medication order, the total inventory of the remaining medicine lanes is calculated to see if it can meet the order. If not, the order is returned. If the current order is met, medication can be dispensed.

[0054] The high-speed drug feeding mechanism 2 starts to operate, driving the front conveyor belt transmission gear mechanism 1 to operate, thereby pushing the drugs forward and dropping them into the medicine hopper. After the priority feeding sensing sensor 3 senses that drugs have fallen, the conveyor belt transmission gear mechanism 1 stops immediately, and the full-material detection grating 4 also detects that the drugs have fallen into the medicine channel, and it can be determined that one box of drugs has been successfully taken; if there are still remaining quantities on the prescription that have not been taken, continue with the above steps; after the drugs are taken, the distance is measured again, and the correct number of drugs taken is calculated based on the numerical value. If too much is taken, the drugs in this medicine hopper will be transferred to the recovery warehouse. If the number of drugs taken is correct, they will be transferred to the drug taking port to complete the order.

[0055] The above-mentioned embodiments only express a certain implementation method of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent of the present invention shall be based on the attached claims.
