BRIEF DESCRIPTION OF THE DRAWINGS

[0065] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments or the prior art descriptions are briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention, and for ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0066] Figure 1 It is the overall module block diagram of the present invention. DETAILED DESCRIPTION

[0067] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0068] The present invention will be further described below in conjunction with the embodiments.

[0069] Example 1 (see Figure 1): A chemical park safety early warning platform, comprising at least:

[0070] The status monitoring module is used to deploy multiple data collectors in the park, including but not limited to data collectors set up in the park's operating area. It should be noted that the data collector in this solution is usually a sensor, which collects various information data in the park. The information data includes temperature, pressure, gas concentration, wind speed, etc., and is synchronously displayed on the control terminal corresponding to the early warning platform to form a visual supervision of the park's status safety.

[0071] Referring to the above, various status data in the park can be monitored by deploying data collectors. At the same time, the data collectors have corresponding coordinate positions, and in this solution, each coordinate position includes multiple data collectors, so that the actual status of the park in the corresponding area can be clarified through data collectors at different coordinate positions.

[0072] Furthermore, in this solution, the output end of the status monitoring module is connected to a risk determination module, which is used to receive information data collected by the triggering warning status data collector during the process of the data collector collecting various status data in the park, thereby marking the data collector corresponding to the information data as a target collector, and obtaining the detection type of the target collector, wherein:

[0073] If the target collector is a smoke collector, and there are multiple smoke collectors in the park that have triggered the warning state, it is necessary to clarify whether the smoke is the same and harmful. If it is the same and harmful, it means that it is the same smoke. Considering that it will cause harm to the operating personnel and operating equipment in the park, therefore:

[0074] The coordinate positions of multiple smoke collectors are obtained, and the risk area is constructed by connecting them according to the coordinate positions of the smoke collectors. Considering that there is smoke between other smoke collectors in the risk area, but it is not detected due to low concentration, therefore:

[0075] Obtain the smoke collectors outside the risk area that have not triggered the warning state and mark them as edge smoke collectors, and obtain the coordinate position of the edge smoke collectors. From this, the risk area is combined with the edge collectors to construct the smoke risk area ;

[0076] The early warning platform determines the smoke risk area Execute risk warning to indicate the smoke risk area When the operators leave and the risk warning is executed, the warning platform will simultaneously The corresponding operating equipment should be shut down in time to prevent the interior from being corroded by harmful smoke.

[0077] It is worth noting that when the smoke is in the process of flowing, the smoke risk area can also be predicted by Fick's second law. , the specific method is:

[0078] Determine the safe threshold of smoke concentration ;

[0079] Solve the diffusion equation analytically:

[0080] according to:

[0081]

[0082] The analytical solution is:

[0083]

[0084] In the formula, For the location x and time t The gas concentration on D is the diffusion coefficient, is the initial concentration;

[0085] Set up the equation:

[0086] The concentration in the analytical solution Set as safety threshold ,get:

[0087]

[0088] Solving for location x： Rearrange equations to solve them x :

[0089]

[0090] Therefore, the time is calculated t The smoke concentration reaches the safety threshold Location x;

[0091] By location x Constructing smoke risk areas .

[0092] Associated risk control module, which is used in smoke risk areas When the operating equipment is closed, the closed operating equipment containing the chemical products to be processed is obtained, and the subsequent corresponding production process steps of the closed operating equipment are obtained (the production process steps contain the operating equipment for production or processing), thereby marking the closed operating equipment as closed operating equipment, and obtaining the same closed operating equipment in the park and not in the smoke risk area The operating equipment in the closed operation equipment is marked as the chemical products to be disposed of, and the disposal queue is constructed with the products to be disposed of. , and then, the coordinate position of the corresponding product to be processed is determined according to the coordinate position of the closed operation equipment. Therefore, different products to be processed have different coordinate positions. Therefore, in order to ensure that the products to be processed are processed in time, this solution also includes the following steps:

[0093] S100, obtaining a material dispatcher (AGV transport equipment) whose transport path passes through both the coordinate positions of the products to be processed and the coordinate positions of the operating equipment at the current time, so as to clarify whether different coordinate positions of the products to be processed and the coordinate positions of the operating equipment can all be passed by the corresponding material dispatcher;

[0094] S200: If the material dispatching machine can access the coordinate position of the product to be processed and the coordinate position of the operating equipment, obtain the material dispatching machine that accesses the coordinate position of the product to be processed and the operating equipment, and determine the remaining capacity volume in the material dispatching machine. ;

[0095] S300: Obtain the coordinate position of the product to be processed and the operating equipment passed by the material dispatcher, and determine the single volume of the product to be processed corresponding to the coordinate position of the product to be processed ,thus:

[0096] when When Can at least meet the needs of a single product to be disposed of Loading, in order to improve transportation efficiency:

[0097] Get the total volume of the product to be disposed corresponding to the coordinate position of the product to be disposed (Volume to be processed times the quantity of product to be disposed of);

[0098] If exists When The corresponding material dispatcher is pre-marked as a replacement material dispatcher;

[0099] If not present When When The corresponding material dispatcher is marked as the successor material dispatcher;

[0100] Furthermore, in order to ensure that the replacement material dispatcher can safely perform the transportation operation of chemical products, the following steps need to be performed:

[0101] S400: Determine whether the transport path of the replacement material dispatcher passes through the smoke risk area ,in:

[0102] S410A, if not passing through the smoke risk area hour,:

[0103] Mark the coordinate positions of the products to be disposed and the coordinate positions of the operating equipment as execution points, and transmit the execution points to the successor material dispatcher to enable it to perform the transportation operation;

[0104] S410B, if passing through a smoke risk area hour:

[0105] Determine the operation point where the material dispatcher needs to perform operations (the operation point refers to the coordinate position where the material dispatcher loads and unloads chemical products and performs other handling and loading), and determine whether the operation point is in the smoke risk area If there is:

[0106] You will be in the smoke risk area The operation points in the process are marked as invalid operation points (and transmitted to the replacement material dispatcher, and no operation is performed on the invalid operation points), so as to exclude the other operation points of the invalid operation points from being marked as execution operation points (including the coordinate position of the product to be disposed and the coordinate position of the running operation equipment to load or unload the chemical product and the original historical operation point of the replacement material dispatcher), and avoid the smoke risk area To regenerate the transportation path that takes over the material dispatcher (the transportation path can be determined by using Dijkstra algorithm or Bellman-Ford algorithm, etc., which will not be described in detail here);

[0107] S420. Obtain the latest processing time of the product to be processed , to obtain the time it takes for the replacement material dispatcher to arrive at the coordinate position of the operating equipment along the transportation path ,in:

[0108] S420A, , it means that The replacement material dispatcher is sufficient to transport the product to be processed to the coordinate position of the operating equipment, so as to facilitate the processing of the product to be processed, so that the replacement material dispatcher can perform the transportation operation;

[0109] S420B, , it means that The material dispatcher can transport the product to be processed to the coordinate position of the operating equipment to facilitate the processing of the product to be processed, so that the material dispatcher can perform the transportation operation;

[0110] Among them, but because , which may cause delays. In order to ensure that the replacement material dispatcher can transport the products to be disposed to the coordinate position of the operating equipment, other material dispatchers other than the replacement material dispatchers in the park are obtained to generate avoidance instructions for the replacement material dispatcher and transmit them to other material dispatchers. Thus, other material dispatchers are rebuilt with the transportation path avoided according to the transportation path of the replacement material dispatcher, thereby ensuring that the replacement material dispatcher in this case can complete the transportation of the products to be disposed;

[0111] Among them, the time for other material dispatchers to execute the avoidance instructions of the replacement material dispatcher is , so in After that, there is no need to execute it, so as to form an accurate and reasonable execution of the avoidance instruction of the material dispatcher;

[0112] S420C, , it means that The successor material dispatcher cannot transport the product to be processed to the coordinate position of the operating equipment, which is inconvenient for processing the product to be processed. The successor material dispatcher is prohibited from performing the transportation operation, so steps S100-S400 are re-executed and other successor material dispatchers are determined.

[0113] In this way, the products to be disposed in the closed operation equipment can be distributed and processed continuously, ensuring the uninterrupted production and processing of chemical products, while avoiding the situation where chemical products cannot be processed and cause material damage, resulting in resource cost loss;

[0114] It is worth mentioning that, here, the replacement material dispatcher determined by limiting method can realize the reasonable utilization of the material dispatcher to the greatest extent, while reducing the utilization loss of resources.

[0115] In the above, the replacement material dispatcher relies on the smoke risk area After reconstructing the transportation route, obtain the estimated operation time of the replacement material dispatcher at the historical operation point (Time spent initially operating on the transport path), where:

[0116] When the early warning platform is in early warning, according to the smoke risk area The early warning platform generates corresponding disposal plans (such as spraying purifiers, etc.) for the affected state. The disposal plan refers to the treatment of the smoke risk area. The response plan for internal smoke elimination and purification is matched according to different smoke presets, and the smoke risk area is judged according to the execution of the disposal plan. Purification time when the air is purified (According to the time of executing the disposal plan, go to the smoke risk area time when the indoor air reaches the safety standard), according to the smoke risk area The time required for purification in the area with the highest smoke concentration is determined to ensure sufficient safety in the park. Therefore:

[0117] When , the running path of the succeeding material dispatcher remains unchanged;

[0118] At After Marked as safe time, After that, the material dispatcher that takes over the smoke risk area The transportation route is rebuilt based on the shortest path. It should be noted that in the smoke risk area After the release, it is also necessary to The equipment in the internal working area is monitored for status. Therefore, the original invalid coordinate points of the successor material dispatcher continue to be marked and not released. The release is executed when the early warning platform confirms that it is correct, and then the successor material dispatcher re-determines the transportation route.

[0119] Finally, the estimated operation time of the replacement material dispatcher at the historical operation point When confirmed:

[0120] Obtained under the reconstructed transport path:

[0121] The execution operation point includes the time to reach the coordinate position of the operating equipment (determined according to the constructed transportation path and calculated according to the preset driving speed of the successor material dispatcher) and the time to operate at the coordinate position of the operating equipment (determined according to the time of unloading of the successor material dispatcher, usually the preset unloading time), the time to reach the effective operation point and the preset operation time at the effective operation point (preset operation time). The sum of multiple time lengths is the actual estimated operation time. ,in:

[0122] When, according to and Make a difference to get continuous allocation time xt (It should be noted that by Applied to the current world time, we can determine The corresponding actual world time, thus obtaining the continuous distribution time xt corresponding world time) to continuously distribute time xtAllow this replacement material dispatcher to perform other transportation operations, so that the coordinate position of the replacement material dispatcher completing the operation under the transportation path can be used to obtain the products to be disposed of that are not currently being transported, in combination with the continuous allocation time. xt and Latest processing time of products to be disposed of Determine whether to perform transportation (continuous allocation time) xt Once the world time is determined, you can perform comparison and continuously distribute time xt Indicates the current replacement material dispatcher can continue to perform the transportation operation to reach the world time), if the continuous allocation time xt Latest processing time , it will take over the material dispatching machine to execute the transportation operation, otherwise it will not execute it. This will form a reasonable scheduling and utilization of the material dispatching machine that takes over, save resources and the early warning platform from the tediousness of frequently allocating operations to the material dispatching machine, and improve the immediate efficiency of the operation.

[0123] When this occurs, the taking-over material dispatcher is not allowed to perform other transportation operations.

[0124] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
