Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of medical industry logistics, and more particularly, to a single-line conveying line hospital box logistics method with dynamic switching of forward and reverse modes. BACKGROUND

[0002] This background section generally presents the context of the present disclosure. To the extent the work of the present inventors in the making of the disclosure and to the extent the descriptions in this background section are not considered prior art by virtue of their date, they are neither expressly nor impliedly admitted to be prior art against the present disclosure.

[0003] In the existing hospital box logistics system, the horizontal exchange layer is usually connected to the vertical sorting machine system of the vertical exchange layer of different areas by double-line conveying lines (two groups of horizontally arranged or vertically arranged main horizontal conveying sorting lines).

[0004] However, due to the complexity of the structure of the hospital building (for example, ducts such as air ducts and fire ducts occupy space) and the requirement of the hospital for the net height of the floor, some areas of the hospital cannot deploy a double-line system (cannot be connected by two groups of horizontal conveying sorting lines) and have to use a single-line conveying line (only one group of horizontal conveying sorting lines) to connect each area.

[0005] However, the existing single-line conveying line control scheme has defects: a certain direction (such as the dispatching direction) is the default direction, and the other direction (such as the return direction) needs to be manually requested to switch or switched at a fixed time (fixed time period for dispatching, such as 8:00-10:00 for dispatching only), and the switching process needs to wait for the current task to be completely emptied; therefore, the efficiency is low, and the actual utilization rate of the transport capacity is reduced, and resources are idle; moreover, when the accumulated transfer boxes on one side exceed the capacity of the buffer area (such as the return boxes in the ward accumulating ≥20 boxes), the logistics system is in a deadlock, and manual intervention is required.

[0006] In view of the above deficiencies, it is necessary to develop a single-line conveying line hospital box logistics method with dynamic switching of forward and reverse modes to improve the operation efficiency and stability and reduce the risk of system congestion failure. SUMMARY

[0007] One object of the present disclosure is to solve the operation efficiency and stability of the hospital box logistics system, reduce the risk of system congestion failure, and develop a single-line conveying line hospital box logistics method with dynamic switching of forward and reverse modes.

[0008] In order to achieve the above-mentioned purpose, the first aspect of the present disclosure proposes a single-line conveying line hospital box logistics method for dynamically switching forward and reverse modes, which is applied to a single-line conveying line hospital box logistics system comprising a controller and a forward and reverse conveying section, wherein the box logistics method comprises the following steps:

[0009] The controller dynamically switches the forward and reverse conveying section to a forward mode or a reverse mode, so as to bidirectionally transport the transfer box between the inpatient pharmacy and the inpatient ward via the forward and reverse conveying section;

[0010] In the forward mode, the transfer box is transported from the inpatient pharmacy to the inpatient ward via the forward and reverse conveying section; in the reverse mode, the transfer box is transported from the inpatient ward to the inpatient pharmacy via the forward and reverse conveying section.

[0011] In summary, compared with the prior art, the beneficial technical effects of the present disclosure mainly lie in the following aspects:

[0012] Based on the real-time transfer box quantity statistics and the target section vacancy, the forward and reverse modes are dynamically switched, avoiding the idle of transport capacity caused by fixed time period mode, improving the transport efficiency of single conveying line, and reducing the idle time of single conveying line. For the direction with high priority, preferential scheduling is performed. The dynamic switching forward and reverse mode of the single conveying line is actively managed, the priority order can be set to ensure that critical tasks are executed in time.

[0013] The photoelectric switch has high precision and can accurately detect the number of transfer boxes and the number of vacancies in real time, thereby improving the accuracy of logistics transmission and reducing the risk of transfer box jamming or damage. The combination of high-precision sensors (such as photoelectric switches) and intelligent algorithms improves the accuracy of logistics transmission.

[0014] Significantly reduces downtime and the number of manual interventions, eliminates the risk of system deadlock: through the active congestion prediction mechanism, it prevents global paralysis caused by one-sided transfer box backlog. Improves the operation efficiency of the hospital logistics system. The transfer box can smoothly enter and exit the forward and reverse conveying section, improving the speed and reliability of logistics transmission. Prolong the service life of the equipment, reduce the dependence on professional maintenance personnel.

[0015] Further areas of applicability will become apparent from the description provided herein. It should be understood that the description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.

[0061] In one embodiment of the present disclosure, the pharmacy transfer machine is connected to the pharmacy dispatch section or the pharmacy return section at one end and to the positive and negative rotation conveying section at the other end. The pharmacy transfer machine is located on the inpatient pharmacy side and is used to vertically lift the transfer box transmitted from the pharmacy dispatch section to the positive and negative rotation conveying section when the single-line conveying line hospital box logistics system is switched to the positive rotation mode.

[0062] In one embodiment of the present disclosure, the ward transfer machine is connected to the ward dispatch section or the ward return section at one end and to the positive and negative rotation conveying section at the other end. The ward transfer machine is located on the inpatient ward side and is used to vertically lift the transfer box transmitted from the ward return section to the positive and negative rotation conveying section when the single-line conveying line hospital box logistics system is switched to the negative rotation mode.

[0063] In one embodiment of the present disclosure, the positive and negative rotation conveying section is used to horizontally transmit the transfer box between the pharmacy transfer machine and the ward transfer machine in the positive rotation mode or the negative rotation mode; wherein a second photoelectric sensor is provided, which is used to monitor and count the number of transfer boxes C 正反2 and the number of empty spaces S 正反2 in the positive and negative rotation conveying section in real time. Wherein the number of empty spaces S 正反2 in the positive and negative rotation conveying section = T 正反2 - C 正反2 . Wherein T 正反2 is the total number of box positions of the positive and negative rotation conveying section.

[0064] In one embodiment of the present disclosure, in the positive rotation mode, the pharmacy dispatch section is used to horizontally transmit the transfer box from the inpatient pharmacy to the pharmacy transfer machine; wherein a first photoelectric sensor is provided, which is used to monitor and count the number of transfer boxes C 发1 and the number of empty spaces S 发1 in the pharmacy dispatch section in real time. Wherein the number of empty spaces S 发1 in the pharmacy dispatch section = T 发1 - C 发1 . Wherein T 发1 is the total number of box positions of the pharmacy dispatch section.

[0065] In one embodiment of the present disclosure, in the positive rotation mode, the ward dispatch section is used to horizontally transmit the transfer box from the ward transfer machine to the inpatient ward; wherein a third photoelectric sensor is provided, which is used to monitor and count the number of transfer boxes C 发3 and the number of empty spaces S 发3 in the ward dispatch section in real time. Wherein the number of empty spaces S 发3 in the ward dispatch section = T 发3 - C 发3 . Wherein T 发1is the total number of box positions of the ward box sending section.

[0066] In one specific embodiment of the present disclosure, in the reverse mode, the ward box returning section is used for horizontal transfer of transfer boxes from the inpatient ward to the ward transfer machine; wherein a fourth photoelectric sensor is arranged for real-time monitoring and counting the number C 返4 of transfer boxes in the ward box returning section and the number S 返4 of empty positions. Wherein the number S 返4 of empty positions in the ward box returning section is S 返4 = T 返4 -C 返4 . Wherein T 返5 is the total number of box positions of the ward box returning section.

[0067] In one specific embodiment of the present disclosure, in the reverse mode, the pharmacy box returning section is used for horizontal transfer of transfer boxes from the pharmacy transfer machine to the inpatient pharmacy; wherein a fifth photoelectric sensor is arranged for real-time monitoring and counting the number C 返5 of transfer boxes in the pharmacy box returning section and the number S 返5 of empty positions. Wherein the number S 返5 of empty positions in the pharmacy box returning section is S 返5 = T 返5 -C 返5 . Wherein T 发3 is the total number of box positions of the pharmacy box returning section.

[0068] In one specific embodiment of the present disclosure, the controller is configured to switch the forward mode or the reverse mode according to the number of transfer boxes.

[0069] In one specific embodiment of the present disclosure, when the single-line conveying line hospital box logistics system is in the forward mode, the pharmacy box sending section is released to transfer transfer boxes to the pharmacy transfer machine based on the remaining empty positions S 发3 of the ward box sending section (for example, 20), and the number of transfer boxes in the released pharmacy box sending section is not more than the remaining empty positions S 发3 of the ward box sending section. Wherein the calculation of releasing transfer boxes based on the remaining empty positions S 发3 of the pharmacy box returning section includes: based on the total number of box positions T 发3 of the ward box sending section (a preset value, for example, 30) and the current number of boxes C 发3 of the ward box sending section, calculating: the remaining empty positions S 发3 of the ward box sending section S 发3 = the total number of box positions T 发3 of the ward box sending section - the current number of boxes C 发3 of the ward box sending section; the number of transfer boxes in the released pharmacy box sending section is not more than the remaining empty positions S 发3≤5, immediately stop transporting the transfer boxes from the pharmacy return box section to the pharmacy transfer machine in the forward rotation mode.

[0070] Beneficial technical effects: In one specific embodiment of the present disclosure, the number of transfer boxes and the number of empty spaces in the pharmacy return box section, the pharmacy dispatch box section, the forward-reverse rotation conveying section, the ward dispatch box section, and the ward return box section are counted through the photoelectric switch information. The number of transfer boxes in the pharmacy return box section, the pharmacy dispatch box section, the forward-reverse rotation conveying section, the ward dispatch box section, and the ward return box section are counted through the photoelectric switch information. This avoids releasing too many transfer boxes, leading to congestion, and ensures that each conveying section does not exceed the capacity, avoiding a dead loop.

[0071] In one specific embodiment of the present disclosure, when the single-line conveying line hospital box logistics system is in the forward rotation mode, when the number C 返4 of transfer boxes in the ward return box section is greater than or equal to a first preset threshold N1 (for example, 15), the pharmacy dispatch box section temporarily stops transporting transfer boxes to the pharmacy transfer machine, and the pharmacy dispatch box section temporarily stores the transfer boxes, waiting for the forward-reverse rotation conveying section to be emptied. After the number of empty spaces in the forward-reverse rotation conveying section, the pharmacy transfer machine, and the ward transfer machine is zero, the single-line conveying line hospital box logistics system is switched to the reverse rotation mode. After switching the direction, the number of transfer boxes in each conveying section is continuously monitored in real time, and the comparison with the relevant threshold is repeated according to the new data for dynamic switching to achieve efficient and automatic circulation.

[0072] In one specific embodiment of the present disclosure, when the single-line conveying line hospital box logistics system is in the reverse rotation mode, the number of transfer boxes released from the ward return box section to the ward transfer machine is based on the remaining empty spaces S 返5 of the pharmacy return box section (for example, 20). The number of transfer boxes released from the ward return box section does not exceed the remaining empty spaces S 返5 of the pharmacy return box section. 返5 The calculation of releasing transfer boxes based on the remaining empty spaces S 返5 of the pharmacy return box section includes: based on the total number of box spaces T 返5 of the pharmacy return box section (a preset value, for example, 30) and the current number of boxes C 返5 of the pharmacy return box section, calculating: the remaining empty spaces S 返5 of the pharmacy return box section = the total number of box spaces T 返5 of the pharmacy return box section - the current number of boxes C 返5 of the pharmacy return box section. The number of transfer boxes in the released ward return box section does not exceed the remaining empty spaces S 返5 of the pharmacy return box section.

[0073] Beneficial technical effects: avoid releasing too many transfer boxes, causing congestion; ensure that each conveying section does not exceed capacity, avoiding dead loops.

[0074] In one specific embodiment of the present disclosure, when the single-line conveying line hospital box logistics system is in reverse mode, when the number C of transfer boxes in the pharmacy box sending section is greater than or equal to a second preset threshold N2 (for example, 15) 发1 When the number of empty spaces in the forward-reverse conveying section, the pharmacy transfer machine and the ward transfer machine is zero, the single-line conveying line hospital box logistics system is switched to forward mode. After switching the direction, the number of transfer boxes in each conveying section is continuously monitored in real time, and comparisons with the relevant thresholds are repeated according to the new data for dynamic switching to achieve efficient and automated circular operation.

[0075] Figure 1 A flowchart of a dynamic switching forward-reverse mode single-line conveying line hospital box logistics method according to one specific embodiment of the present disclosure. As shown in Figure 1 In one specific embodiment of the dynamic switching forward-reverse mode single-line conveying line hospital box logistics method of the present disclosure, in forward mode, the running route direction of the transfer box is: from the pharmacy box sending section to the ward box sending section through the pharmacy transfer machine, the forward-reverse conveying section and the ward transfer machine. As shown in Figure 1 The running route from the pharmacy box sending section to the ward box sending section through the pharmacy transfer machine, the forward-reverse conveying section and the ward transfer machine is the forward direction; the forward direction is from the inpatient pharmacy to the inpatient ward.

[0076] As shown in Figure 1 In one specific embodiment of the dynamic switching forward-reverse mode single-line conveying line hospital box logistics method of the present disclosure, in reverse mode, the running route direction of the transfer box is: from the ward box returning section to the pharmacy box returning section through the ward transfer machine, the forward-reverse conveying section and the pharmacy transfer machine. The running route from the ward box sending section to the pharmacy box returning section through the ward transfer machine, the forward-reverse conveying section and the pharmacy transfer machine is the reverse direction; the reverse direction is from the inpatient ward to the inpatient pharmacy.

[0077] Beneficial technical effects: the present disclosure actively optimizes the use of transport capacity by pausing or releasing the transfer of transfer boxes and dynamically switching the forward-reverse direction running route, to avoid transfer box congestion (such as too many transfer boxes on one side causing box congestion).

[0078] In one specific embodiment of the present disclosure, when the pharmacy dispatching section and the ward returning section have transport boxes arriving at the same time, the priority of the two horizontal conveying sections, the pharmacy dispatching section and the ward returning section, is compared, and the transport box in the horizontal conveying section with higher preset priority is conveyed first. For example, if the pharmacy dispatching section has higher priority, the transport box in the pharmacy dispatching section is conveyed first; if the ward returning section has higher priority, the transport box in the ward returning section is conveyed first.

[0079] Beneficial technical effects: flexible handling of peak periods when the pharmacy dispatching section and the ward returning section request to convey transport boxes at the same time, improving overall efficiency. Overcomes the low efficiency problem caused by the lack of priority in the prior art, optimizes resource allocation.

[0080] In one specific embodiment of the present disclosure, if there is a transport box arriving in the pharmacy dispatching section and the pharmacy dispatching section has high priority, the positive and negative conveying section is switched to continue running in the positive direction; at this time, the transport box from the ward returning section is paused into the ward transfer machine and waits in the ward returning section; at the same time, the number of transport boxes and the number of empty positions in the ward returning section are counted through the photoelectric switch signal.

[0081] If the cumulative number of transport boxes in the ward returning section is greater than or equal to the set threshold, the transport of the pharmacy dispatching section into the pharmacy transfer machine is paused, and the number of transport boxes and the number of empty positions in the pharmacy dispatching section are counted through the photoelectric switch signal.

[0082] After the transport boxes that have entered the positive and negative conveying section completely arrive in the ward dispatching section, the current positive and negative conveying section is switched to the reverse mode to transport a part of the transport boxes in the ward returning section to the pharmacy returning section. The number of transport boxes transported is determined according to the remaining empty positions of the pharmacy returning section.

[0083] If the remaining empty positions of the pharmacy returning section are insufficient, the transport of the transport boxes from the ward returning section into the ward transfer machine is paused to prevent too many transport boxes in the positive and negative conveying section and to avoid causing the positive and negative conveying section to be blocked.

[0084] If the cumulative number of transport boxes in the pharmacy dispatching section is greater than or equal to the set threshold, the transport of the transport boxes from the ward returning section into the ward transfer machine is paused.

[0085] After the transport boxes that have entered the positive and negative conveying section completely arrive in the pharmacy returning section, the current positive and negative conveying section is switched to the positive mode to transport a part of the transport boxes in the pharmacy dispatching section to the ward dispatching section, and the specific number is determined according to the remaining empty positions of the ward dispatching section; this cycle is repeated.

[0086] In one specific embodiment of the present disclosure, if there is a transfer box arriving in the ward return box section and the priority of the ward return box section is high, the positive and negative reverse conveying section switches to the reverse direction to continue running; at this time, the transfer box from the pharmacy box sending section is paused to enter the pharmacy transfer machine and waits in the pharmacy box sending section; at the same time, the number of transfer boxes and the number of empty positions in the pharmacy box sending section are counted through the photoelectric switch signal.

[0087] If the cumulative number of transfer boxes in the pharmacy box sending section is greater than or equal to the set threshold, the transportation of the ward return box section into the ward transfer machine is paused, and the number of transfer boxes and the number of empty positions in the ward return box section are counted through the photoelectric switch signal.

[0088] After the transfer boxes that have entered the positive and negative reverse conveying section completely arrive in the pharmacy return box section, the current positive and negative reverse conveying section is switched to the positive mode to transport a part of the transfer boxes in the pharmacy box sending section to the ward box sending section. The number of transported transfer boxes is determined according to the remaining empty positions of the ward box sending section.

[0089] If the remaining empty positions of the ward box sending section are insufficient, the transfer of the transfer boxes from the pharmacy box sending section into the pharmacy transfer machine is paused to prevent too many transfer boxes in the positive and negative reverse conveying section and to avoid causing the positive and negative reverse conveying section to be blocked.

[0090] If the cumulative number of transfer boxes in the ward box sending section is greater than or equal to the set threshold, the transportation of the transfer boxes from the pharmacy box sending section into the pharmacy transfer machine is paused.

[0091] After the transfer boxes that have entered the positive and negative reverse conveying section completely arrive in the ward box sending section, the current positive and negative reverse conveying section is switched to the positive mode to transport a part of the transfer boxes in the pharmacy box sending section to the pharmacy box sending section, and the specific number is determined according to the remaining empty positions of the pharmacy box sending section; this cycle is repeated.

[0092] In the first specific embodiment, the box sending and returning is performed in time periods.

[0093] The connection scheme between the inpatient pharmacy and the inpatient ward is as follows: the pharmacy return box section contains 15 box positions, the pharmacy box sending section contains 15 box positions, the positive and negative reverse conveying section contains 30 box positions, this section is designed for positive and negative reverse, the ward box sending section contains 20 box positions, and the ward return box section contains 20 box positions; the pharmacy transfer machine and the ward transfer machine are respectively combined top lifting transfer machines.

[0094] From 8:00 to 10:00 in the morning is the box sending time period; from 10:00 to 12:00 is the empty box returning time period; in the morning, there are 50 boxes of medicines to be sent in the inpatient pharmacy, so during the period from 8:00 to 10:00, the system can only perform the conveying task of sending from the pharmacy to the inpatient ward, and the empty transfer boxes after the sending are completed need to wait until 10:00 to start returning to the inpatient pharmacy.

[0095] Disadvantages: If all the transfer boxes are sent out, the hospital pharmacy may have new requirements for sending boxes, and there may be no transfer boxes available; at the same time, from 10:00 to 12:00, if the hospital pharmacy still needs to send boxes, it can only be sent by manual delivery; the convenience and availability of the hospital box logistics system are greatly reduced; and the system cannot be fully utilized.

[0096] In a second specific embodiment, a conventional automatic switching mode is used.

[0097] The connection scheme between the hospital pharmacy and the hospital ward is as follows: the pharmacy return box section contains 15 box positions, the pharmacy sending box section contains 15 box positions, the positive and negative conveying section contains 30 box positions, this section is designed for positive and negative conversion, the ward sending box section contains 20 box positions, and the ward return box section contains 20 box positions; the pharmacy transfer machine and the ward transfer machine are respectively combined top lifting transfer machines;

[0098] Initially, the default position is the direction from the hospital pharmacy to the hospital ward; after the hospital pharmacy sends boxes to the hospital ward, the hospital ward can also return empty boxes at any time, and the empty boxes returned from the hospital ward can be temporarily stored in the ward return box section; at the same time, when the photoelectric switch near the position of the ward transfer machine on the ward return box section detects that there is a transfer box, it sends a request for return box and requests switching to reverse mode, i.e., from the hospital ward return box to the hospital pharmacy; when the system checks that the positive and negative conveying section, the pharmacy transfer machine and the ward transfer machine are all empty, it can be switched to reverse mode, and the empty boxes are sent back to the hospital pharmacy;

[0099] Disadvantages: If the hospital pharmacy is continuously sending boxes, even if the ward return box section has a return box request, it cannot be returned, and when the number of transfer boxes in the ward return box section reaches 20, the subsequent empty boxes returned from the hospital ward cannot be unloaded from the hospital ward to the ward return box section, causing the hospital ward elevator to stop working; the transfer boxes sent to the hospital ward elevator will also stay in the ward sending box section; this system is blocked into a dead loop state, and the transfer boxes in the ward return box section need to be manually processed to restore operation.

[0100] In one specific embodiment of the present disclosure, when the hospital pharmacy starts sending transfer boxes to the hospital ward, if the number of transfer boxes on the ward return box section is less than 15 and the number of transfer boxes on the pharmacy sending box section is greater than 1, the transfer boxes on the pharmacy sending box section are preferentially conveyed, and the transfer boxes run in the positive direction.

[0101] In one specific embodiment of the present disclosure, if the number of transfer boxes on the ward return box section is greater than or equal to 15, then the transfer of the transfer boxes from the pharmacy return box section to the ward transfer machine is temporarily suspended. When the positive and negative transfer section, the pharmacy transfer machine and the ward transfer machine are empty, and the motor is no longer running, the hospital box logistics system switches to the reverse direction operation; at the same time, according to the current remaining box number of the pharmacy return box section, such as there are currently 10 empty positions, the transfer of the transfer boxes from the ward return box section to the ward transfer machine is temporarily stopped.

[0102] In one specific embodiment of the present disclosure, if the number of transfer boxes on the pharmacy return box section is less than 15, then the reverse direction operation is maintained. In one specific embodiment of the present disclosure, if the number of transfer boxes on the pharmacy return box section is greater than 15, then the transfer of the transfer boxes from the ward return box section to the ward transfer machine is temporarily suspended. When the positive and negative transfer section, the pharmacy transfer machine and the ward transfer machine are empty, and the motor is no longer running, the hospital box logistics system switches to the forward direction operation; at the same time, according to the current remaining box number of the pharmacy return box section, such as there are currently 10 empty positions, the transfer of the transfer boxes from the pharmacy return box section to the pharmacy transfer machine is temporarily stopped.

[0103] In one specific embodiment of the present disclosure, by the above control method, the inpatient pharmacy can send out boxes at any time, or receive returned empty boxes at any time; the inpatient ward can also receive the transfer boxes sent by the inpatient pharmacy at any time, and return the empty boxes at any time.

[0104] The present disclosure solves the problem of time limitation of the first specific embodiment of receiving and sending boxes; at the same time, the present method actively controls the transfer boxes entering the positive and negative transfer section, and ensures that the positive and negative transfer section is always kept empty.

[0105] Therefore, the present disclosure also solves the problem of the second specific embodiment that after the positive and negative transfer section is occupied, not only the positive and negative switching cannot be performed, but also the system enters a dead loop state when the ward return box section or the pharmacy box section is full.

[0106] Through the present disclosure, the positive and negative transfer section can be used efficiently, and manual intervention for handling the blocked boxes is avoided, the overall use efficiency is improved, and the user can perform the receiving and sending box task processing at any time.
