[0021] The detection sensor is placed on the side surface of the garbage bin, and the detection sensor is located at 7 / 8 of the garbage bin body, and is used to detect whether the garbage bag is installed properly. The garbage bin is placed on the crawler.

[0022] A method for primary treatment of medical waste using the above-mentioned intelligent trash can comprises the following steps: sequentially cycling through a disinfection stage, a crushing stage, a compression stage, and a capacity detection stage, wherein each time medical waste enters the trash can, the method sequentially cycles through the above stages until the trash can is detected to be full during the capacity detection stage, and then enters a trash bag replacement stage;

[0023] The specific process of the disinfection stage is as follows: when the medical waste enters the waste bin, the pressure measured by the pressure sensor on the pressure plate suddenly increases, wait for 1-2 seconds, and then the power of the ultraviolet lamp is turned on;

[0024] The specific process of the crushing stage is as follows: the moving plate returns to the first positioning origin, which is the uppermost end of the guide rail that the moving plate can reach, and the moving plate moves to a preset position, which is a position where the blade is 5-10 cm away from the plane where the second positioning origin is located. The motor at the upper end of the blade drives the blade to rotate horizontally, and the servo at the moving plate runs to drive the moving plate to rotate left and right. The blade rotates for about 3 seconds, and the time can be set by yourself. The moving plate rotates back to the horizontal position, the blade stops rotating, and the moving plate returns to the first positioning origin; the second positioning origin is the uppermost position of the screw rod that the slide can reach;

[0025] The vertical difference between the second positioning origin and the first positioning origin is the height of the first layer of the trash bin;

[0026] The specific process of the compression stage is as follows: the slide and the pressure plate return to the positioning origin 2, that is, the uppermost end of the screw rod that the slide can reach, the pressure plate rotates to a vertical state, that is, the pressure plate rotates 90 degrees, and the crushed medical waste will fall into the trash bag. When all the medical waste falls into the trash bag, that is, when the pressure plate is empty, the pressure measured by the pressure sensor is equal to the pressure on the pressure plate when it is rotated 90 degrees, and the pressure plate rotates back to a horizontal state, that is, the pressure plate rotates to 0 degrees, the stepper motor rotates, the slide and the pressure plate move down, and when the stall current in the stepper motor reaches the threshold, the slide and the pressure plate no longer move down, the compression stops, and the slide and the pressure plate return to the second positioning origin;

[0027] The detection capacity stage includes: a distance measurement method of a distance sensor and an accumulation method of a pressure sensor,

[0028] The specific process of the distance measuring method using the distance measuring sensor is as follows: when the pressing plate is rotated 90 degrees, the distance measuring sensor detects the height of the medical waste in the garbage bag, and the approximate medical waste capacity can be obtained by multiplying the height by the bottom area of ​​the garbage bin;

[0029] The specific process of the pressure sensor accumulation method is as follows: after replacing the garbage bag, the pressure measured by the pressure sensor on the pressing plate when the pressing plate rotates to 0° after the first crushing is recorded as F1, and the pressure measured by the pressure sensor on the pressing plate when the pressing plate rotates to 0° after the second crushing is recorded as F2, and so on. The calculation of Ftotal = F1 + F2 + ... + Fn is performed, and the weight of the medical waste in the garbage bag can be obtained by dividing Ftotal by the acceleration of gravity.

[0030] The garbage bag replacement stage is: when the medical waste capacity reaches the garbage bin capacity setting value or the medical waste weight reaches the weight setting value, the smart garbage bin 1 sends a signal, the garbage bin door opens, the garbage bin is moved out of the garbage bin body, and the personnel replaces the garbage bag on the garbage bin and installs the garbage bag correctly, that is, the infrared sensor on the garbage bin body detects the garbage bag, the track reverses, the garbage bin barrel returns to the garbage bin body, and the garbage bin door closes.

[0031] A medical waste recycling device, comprising an integrated management platform 2 and a plurality of smart trash bins according to claim 1, wherein the integrated management platform is connected to the plurality of smart trash bins via wireless communication;

[0032] The integrated management platform 2 includes a communication module, a storage module, a processing module and a display screen. The processing module is connected to the communication module, the storage module and the display screen respectively. The processing module is connected to the communication transmission device of the intelligent trash can through the communication module.

[0033] A medical waste collection and transportation method using the above-mentioned medical waste recycling device includes the following steps: a communication transmission device in a waste bin sends location and collection and transportation information to an integrated management platform; a communication module of the integrated management platform receives the information and stores it in a storage module; a processing module calculates an optimal collection and transportation route using a medical waste recycling dynamic scheduling algorithm based on particle swarm optimization; and a display screen displays the optimal collection and transportation route, collection and transportation time, and collection and transportation order.

[0034] According to the above technical solution, the medical waste recycling dynamic scheduling algorithm includes the following steps:

[0035] Step 1: If the vehicle load is less than the total amount of garbage in all the garbage bins to be cleaned, the garbage bins with more garbage will be prioritized, and the garbage bins with less garbage will be eliminated in turn until the vehicle load is greater than or equal to the total amount of garbage to be collected and transported.

[0036] If the vehicle's load is greater than or equal to the sum of the garbage in all the bins to be cleaned, when new garbage bin collection information is received, the vehicle's load is calculated based on the vehicle's load. The vehicle's position may not be at the collection starting point, and the current position is defined as the new starting point.

[0037] Step 2: Based on the location of the collection and transportation vehicles, the location of the medical waste treatment station, and the location and capacity of each garbage bin, a weighted undirected graph is established, and multiple initial solutions are determined using the improved circle algorithm;

[0038] Step 3, using multiple initial solutions, calculate the optimal route through genetic algorithm;

[0039] Step 4: Output and display the results.

[0040] If there are multiple collection vehicles, the following steps are also included before step 1: first, the collection and transportation range of all garbage bins is divided into multiple areas according to the number of collection vehicles, ensuring that each collection vehicle is responsible for one area.

[0041] According to the above technical solution, in step 2, a weighted undirected graph is established based on the location of the collection and transportation vehicle, the location of the medical waste treatment station, and the location and capacity of each garbage bin, and the specific process of determining multiple initial solutions using the improved circle algorithm is as follows:

[0042] Step 2.1: Define the starting position of the collection vehicle as V1, the positions of each garbage bin as V2, ...Vi...Vj..., Vn-1, and the position of the medical waste treatment station as Vn; 1<i<n, 1<j<n, where n is the last station before returning to the starting point;

[0043] Step 2.2, generate the initial circle path: C = V1…V i-1 V i V i+1 …V j-1 V j V j+1 …Vn, and randomly change the order between i and j to get a new path: V1…V i-1 V j V i+1 …V j-1 V i V j+1 …Vn;

[0044] Step 2.3, calculate △f=d Vi-1Vj d ViVj+1 -d Vi-1Vi d VjVj+1 , where d Vi-1Vj Indicates the position point V i-1 and position point V j The distance between ViVj+1 Indicates the position point V i and position point Vj+1 The distance between Vi-1Vi Indicates the position point V i-1 and position point V i The distance between VjVj+1 Indicates the position point V j and position point V j+1 the distance between them;

[0045] If △f < 0, the new path replaces the old path until a feasible solution is obtained without modification;

[0046] Step 2.4, repeat steps 2.1-2.3 to obtain multiple feasible solutions;

[0047] In step 3, the process of calculating the optimal route using a genetic algorithm with multiple initial solutions is as follows:

[0048] Step 3.1: Convert multiple feasible solutions into chromosome codes, forming multiple random number sequences M1…Mk…Mn as chromosomes, where 0<Mk<1 (k=2, 3, …, n-1), M1=0, Mn=1, and Mk represents the random assignment of each trash bin position; each random sequence is regarded as an individual in a population, and multiple random number sequences form the initial population. The encoding position k is the target k, and the random number at position k represents the order of the target k in the tour;

[0049] Step 3.2, calculate the fitness of each individual in the population through the fitness function, the fitness function is where d ViVi+1 Indicates the position point V i and position point V i+1 the distance between them;

[0050] Step 3.3, iterate the population multiple times, calculate the fitness of the population through the fitness function after each iteration, and record it until the number of iterations reaches the set maximum value;

[0051] Step 3.4, select the feasible solution corresponding to the minimum value of the fitness function as the final solution;

[0052] In the step 3.3, the specific process of iteration is: select two parent individuals f1=M1M2…Mn, f2=M1'M2'…Mn', randomly select the tth gene as the crossover point, and then the offspring individuals s1 and s2 obtained after the crossover operation, the genes of s1 are composed of the first t genes of f1 and the last 102-t genes of f2, and the genes of s2 are composed of the first t genes of f2 and the last 102-t genes of f1. There are many options for crossover operations, and the best crossover method should be selected as much as possible to ensure that the offspring can inherit the excellent characteristics of the parent; at the same time, the crossover operation here also implies a mutation operation.

[0053] The present invention has the following beneficial effects:

[0054] 1. The present invention has the function of automatically compressing and crushing garbage, which can maximize the use of the storage space of the garbage box. At the same time, it can preliminarily crush medical waste, prevent abnormal utilization, and have the effect of reducing emissions.

[0055] 2. The present invention provides alcohol spraying for the required personnel to implement, ensuring the cleanliness and safety of personnel when discarding medical waste. At the same time, the pushing and installation functions of the trash can ensure the convenience and reliability of personnel installing garbage bags.

[0056] 3.

The calculation of Ftotal = F1 + F2 + ... + Fn is performed, and the weight of the medical waste in the garbage bag can be obtained by dividing Ftotal by the acceleration of gravity.

[0103] The garbage bag replacement stage is: when the medical waste capacity reaches the garbage bin capacity setting value (the capacity setting value is 3 / 4 of the garbage bin capacity) or the medical waste weight reaches the weight setting value (the weight setting value is 3 / 4 to 7 / 8 of the garbage bag weight limit), the intelligent garbage bin 1 sends a signal through the power supply control module, and the garbage bin door automatically opens. The same structure as the pressure plate rotation can be used here. The garbage bin door is connected to the door drive motor, the DC motor is running, the crawler track rotates forward, and the garbage bin is pushed out. When the personnel replaces the garbage bag on the garbage bin and installs the garbage bag correctly, that is, the infrared sensor on the garbage bin body detects the garbage bag, the crawler track reverses, the garbage bin barrel returns to the garbage bin body, and the garbage bin door closes.

[0104] Furthermore, the method for initial treatment of medical waste also includes an induction cleaning stage. The specific process of the induction cleaning stage is: whenever a person places his hand on the right side of the trash can opening, the infrared sensor on the upper right side of the trash can opening detects the alcohol sprayer and sprays alcohol.

[0105] A medical waste recycling device comprises an integrated management platform 2 and a plurality of the above-mentioned intelligent waste bins, wherein the integrated management platform is connected to the plurality of intelligent waste bins via wireless communication;

[0106] The integrated management platform 2 includes a communication module 201, a storage module 202, a processing module 203 and a display screen 204. The processing module is connected to the communication module 201, the storage module 202 and the display screen respectively, and the processing module is connected to the communication transmission device of the intelligent trash can through the communication module.

[0107] A medical waste collection and transportation method using the above-mentioned medical waste recycling device includes the following steps: a communication transmission device in a waste bin sends location and collection and transportation information to an integrated management platform; a communication module of the integrated management platform receives the information and stores it in a storage module; a processing module calculates an optimal collection and transportation route using a medical waste recycling dynamic scheduling algorithm based on particle swarm optimization; and a display screen displays the optimal collection and transportation route, collection and transportation time, and collection and transportation order.

[0108] The dynamic scheduling algorithm for medical waste recycling includes the following steps:

[0109] In step 1, only one collection vehicle is considered in each garbage collection area. If the vehicle's load is less than the total amount of garbage in all the garbage bins that need to be cleaned, the garbage bins with more garbage will be given priority, and the garbage bins with less garbage will be eliminated in turn (a garbage bin with less garbage can be defined as a garbage bin with more than 40% of its capacity remaining). The garbage bins that are eliminated will have more garbage in the next collection, and will be included in the range that needs to be collected, until the vehicle's load is greater than or equal to the total amount of garbage to be collected;

[0110] If the vehicle's load is greater than or equal to the sum of the garbage in all the bins to be cleaned, when new garbage bin collection information is received, the vehicle's load is calculated based on the vehicle's load. The vehicle's position may not be at the collection starting point, and the current position is defined as the new starting point.

[0111] Step 2: Based on the location of the collection and transportation vehicles, the location of the medical waste treatment station, and the location and capacity of each garbage bin, a weighted undirected graph is established, and multiple initial solutions are determined using a modified circle algorithm. When the garbage in the garbage bin reaches approximately 80% of its capacity, a collection information is sent to the collection and transportation platform.

[0112] Step 3, using multiple initial solutions, calculate the optimal route through genetic algorithm;

[0113] Step 4: Output and display the results.

[0114] If there are multiple collection vehicles, the following steps are also included before step 1: first divide the collection and transportation range of all garbage bins into multiple areas according to the number of collection vehicles, ensuring that each collection vehicle is responsible for one area. This situation is the same as when there is only one collection vehicle.

[0115] Furthermore, in step 2, a weighted undirected graph is established based on the location of the collection and transportation vehicle, the location of the medical waste treatment station, and the location and capacity of each garbage bin, and the specific process of determining multiple initial solutions using the improved circle algorithm is as follows:

[0116] Step 2.1: Define the starting position of the collection vehicle as V1, the positions of each garbage bin as V2, ...Vi...Vj..., Vn-1, and the position of the medical waste treatment station as Vn; 1<i<n, 1<j<n, where n is the last station before returning to the starting point;

[0117] Step 2.2, generate the initial circle path: C = V1…V i-1 V i V i+1 …V j-1 V j V j+1 …Vn, and randomly change the order between i and j to get a new path: V1…V i-1 V j V i+1 …V j-1 V i V j+1 …Vn;

[0118] Step 2.3, calculate △f=d Vi-1Vj d ViVj+1 -d Vi-1Vi d VjVj+1 , where d Vi-1Vj Indicates the position point V i-1 and position point Vj The distance between ViVj+1 Indicates the position point V i and position point V j+1 The distance between Vi-1Vi Indicates the position point V i-1 and position point V i The distance between VjVj+1 Indicates the position point V j and position point V j+1 The distance between the two points; the path between the two points can be converted into the shortest path, and then the corresponding distance is used to replace the corresponding path;

[0119] If △f < 0, the new path replaces the old path until a feasible solution is obtained without modification;

[0120] Step 2.4, repeat steps 2.1-2.3 to obtain multiple feasible solutions;

[0121] In step 3, the process of calculating the optimal route using a genetic algorithm with multiple initial solutions is as follows:

[0122] Step 3.1, convert N feasible solutions into chromosome codes, forming random number sequences M1…Mk…Mn as chromosomes, where 0<Mk<1(k=2, 3, …, n-1), M1=0, Mn=1, Mk represents the random assignment of each trash bin position; each random sequence is regarded as an individual in a population, multiple random number sequences form the initial population, the encoding position k is the target k, and the random number at position k represents the order of the target k in the tour; ensure that M1 and Mn are in the same order after the tour. N The position is fixed and corresponds to V1 (the starting point of collection and transportation) N The order of (collection and transportation destination) in the route remains unchanged, achieving the effect of starting from the starting point and ending at the destination;

[0123] Step 3.2, calculate the fitness of individuals in the population through the fitness function, the fitness function is where d ViVi+1 Indicates the position point V i and position point V i+1 the distance between them;

[0124] Step 3.3,

[0125] The population is iterated multiple times. After each iteration, the fitness of the population is calculated using the fitness function and recorded until the number of iterations reaches the set maximum value.

[0126] Step 3.4, select the feasible solution corresponding to the minimum value of the fitness function as the final solution;

[0127] Furthermore, the maximum number of iterations is set to 40-60, and the optimal value of the number of iterations can be selected as 50;

[0128] In the step 3.3, the specific process of iteration is: select two parent individuals f1=M1M2…Mn, f2=M1'M2'…Mn', randomly select the tth gene as the crossover point, and then the offspring individuals s1 and s2 obtained after the crossover operation, the genes of s1 are composed of the first t genes of f1 and the last nt genes of f2, and the genes of s2 are composed of the first t genes of f2 and the last nt genes of f1. There are many ways to choose the crossover operation, and the best crossover method should be selected as much as possible to ensure that the offspring can inherit the excellent characteristics of the parent; at the same time, the crossover operation here also contains the mutation operation.

[0129] The above are only preferred embodiments of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope of protection of the present invention.
