Description

Technical Field

[0001] The present invention belongs to the technical field of emergency communication guarantee, and in particular relates to an emergency communication guarantee scheduling method based on backup power duration and travel time. Background Art

[0002] When a major natural disaster such as an earthquake or mudslide occurs, it is extremely important to quickly and effectively restore communication base stations, complete power backup for the base stations, and restore communications as soon as possible. In the event of a mains power outage, there are currently two main solutions for base station power backup:

[0003] (1) The backup power supply for communication base stations is mainly provided by dispatching maintenance orders through the backend, and then the backup power supply is provided to the base stations through diesel generators.

[0004] (2) Install a cloud-controlled oil generator and remotely start the oil generator for backup power.

[0005] Although the above existing solutions can meet the daily base station maintenance needs, they still have the following shortcomings:

[0006] (1) The dispatch efficiency of maintenance personnel is low. When a major natural disaster occurs, the distribution of nearby maintenance personnel cannot be determined in a timely manner, and the corresponding personnel cannot be dispatched from the nearest place to rush to the disaster site as soon as possible, thus missing the best rescue time.

[0007] (2) Lack of understanding of existing resources. When a major natural disaster occurs, it is impossible to organize the dispatch of emergency resources in a timely and effective manner to achieve rapid power backup and emergency repairs for the affected base stations.

[0008] (3) There is no accurate data support for the power backup status of existing base stations and the travel time to the base stations; for the power backup guarantee of base stations, it is impossible to distinguish the priority data in a short period of time and it is impossible to take the overall situation into consideration, resulting in the situation of neglecting one thing while focusing on another.

[0009] Therefore, how to overcome the shortcomings of existing technologies is an urgent problem to be solved in the field of emergency communication support technology. Summary of the Invention

[0010] The purpose of the present invention is to solve the deficiencies of the prior art and provide an emergency communication guarantee scheduling method based on backup power time and travel time.

[0011] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0012] The emergency communication guarantee scheduling method based on the backup power time and the travel time includes the following steps:

[0013] Step 1: Obtain the emergency events and response levels that need to be protected. Based on the areas involved in the emergency events, determine the number and location distribution of communication base stations to be protected. At the same time, combined with the protection levels of the communication base stations, finally determine the list of communication base station sites to be protected as the emergency protection task list; establish a protection task list database to store the basic data of the communication base station sites to be protected;

[0014] Step 2: Establish a material reserve database, then query the emergency material reserve points in the area involved in the emergency incident, as well as the material reserve status of each reserve point, and determine whether the emergency material reserve status meets the emergency material reserve guarantee requirements for the emergency incident that needs to be guaranteed obtained in step 1;

[0015] The material reserve database includes information on the location of material storage, the type of material, the information on emergency material custodians, and the conditions for obtaining and using the material;

[0016] Step 3: Establish an emergency support personnel information database, then query the information of emergency support personnel in the area involved in the emergency event, and determine whether the emergency support personnel information meets the emergency support personnel protection requirements for the sudden emergency event that needs to be protected obtained in step 1;

[0017] Among them, the emergency support personnel information database includes basic personnel information, personnel location information and personnel's emergency skills;

[0018] Step 4: Based on the emergency support task list determined in step 1, query the location information of the emergency support material storage, the location information of the emergency support personnel, and the location information of the communication base station sites in the task list, calculate the travel time Tf to each target communication base station in the emergency support task list, and store it in the support task list database;

[0019] Step 5: Calculate the backup power time Tb of each base station in the proposed emergency support task list based on the backup power data information of each communication base station site in the emergency support task list, and store it in the support task list database;

[0020] Step 6: Based on the backup power time and the travel time of the base station, generate the optimal protection path map for each communication base station site in the emergency protection task list, as well as the corresponding emergency protection materials and emergency protection personnel, to form a protection plan for a single site; calculate the score of each communication base station site in the emergency protection task list, generate a score table for each communication base station site in the emergency protection task list, and store it in the protection task list database; based on the optimal protection path map, calculate the Tb-Tf difference table for each communication base station site in the protection task list, and store it in the protection task list database;

[0021] Step 7: Execution of the protection plan. Based on the importance of the event to be protected and the economic feasibility of the protection event, choose one of the following two strategies to implement the corresponding protection plan;

[0022] The first strategy is to calculate the ranking of the sites in the security task list based on their importance, and then implement the security plans in each security task list in descending order.

[0023] The second strategy is to sort by the time difference Tb-Tf, from small to large, and execute the support plans in each support task list in sequence.

[0024] Furthermore, in step 1, the response levels for emergencies include Level I, Level II, Level III, and Level IV;

[0025] The basic data of the communication base station site includes: base station name, communication equipment resource data involved in the base station, base station load data, base station code, base station location information, base station security level and base station coverage scenarios.

[0026] Furthermore, in step 2, the location information of material storage includes longitude, latitude, and specific storage address; the types of materials include backup batteries, generators, emergency kits, vehicles, satellite phones, walkie-talkies, and kayaks; the information of the person in charge of emergency materials includes name and contact information; and the conditions for obtaining materials include the approval process and the person in charge.

[0027] Furthermore, in step three, the basic information of the personnel includes name, gender, ethnicity, age, affiliation, contact number and emergency contact number;

[0028] Personnel location information is the real-time location information of personnel;

[0029] The emergency skills of the personnel include: oil engine power generation and troubleshooting skills, battery installation and troubleshooting skills, switching power supply installation and troubleshooting skills, and power cable laying and handling skills.

[0030] Further, in step five:

[0031] If the communication base station uses battery backup, the backup time = battery pack capacity multiplied by battery pack voltage divided by equipment power multiplied by power factor;

[0032] If the communication base station uses cloud-controlled oil generator backup power, the backup power duration is calculated based on the oil reserve of the oil generator;

[0033] If the communication base station uses both batteries and cloud-controlled oil generators for backup power, the backup time is the sum of the battery backup time and the cloud-controlled oil generator backup time.

[0034] Furthermore, in step 6, the specific method for calculating the score of each communication base station site in the emergency support task list is:

[0035] If the communication base station site is a custom priority site, the communication base station site score is 100 points; otherwise, it is calculated according to the following formula:

[0036] The communication base station site score = the communication base station site scenario weight value score + the emergency material storage weight value score in the site's security plan + the communication base station site power backup time weight value score + the emergency support personnel travel time weight value score in the site's security plan.

[0037] Furthermore, in step seven, if the time difference calculated by the second strategy is within a range of plus or minus 10 minutes, the protection plan is executed according to the first strategy.

[0038] In step 2 of the present invention, it is determined whether the emergency material reserve situation meets the emergency material reserve guarantee requirements of the sudden emergency event that needs to be guaranteed obtained in step 1, that is, it is determined whether the emergency material reserve situation matches the emergency event and the response level.

[0039] In step three of the present invention, it is determined whether the emergency support personnel information meets the protection requirements of the emergency support personnel for the sudden emergency event that needs to be protected obtained in step one, that is, it is determined whether the personnel location information and the emergency skills they possess match the protection requirements of the above-mentioned emergency support personnel.

[0040] In step three of the present invention, the personnel location information includes longitude and latitude, which must be the personnel's real-time location information. The personnel's location information can be read in real time through mobile phone positioning or other positioning devices.

[0041] In step seven of the present invention, the first strategy is to prioritize the importance of security, and the second strategy is to take economic efficiency into consideration while ensuring the importance of security.

[0042] The present invention establishes the following contents:

[0043] (1) Establish an emergency support personnel information database and a material reserve database: Use GPS or Beidou to locate the positions of emergency support personnel and emergency support materials, store and present them in the system, and grasp the distribution of emergency resources in real time.

[0044] (2) Establish basic data to ensure the backup power time of base stations: Calculate the backup power time of base stations based on the capacity of the backup batteries of existing base stations and the load conditions of the base stations, store and present them in the system, and grasp the distribution of the backup power time of base stations in real time.

[0045] (3) Establish travel time data between the support base station and the support personnel: Determine the target site that needs to be protected, and calculate the travel time data based on the location information of the support personnel and the target base station.

[0046] (4) Based on the backup power time and travel time of the base station, generate the best support path map for each communication base station site in the emergency support task list, as well as the corresponding emergency support materials and emergency support personnel, to form a support plan for a single site; calculate and generate a score table for each communication base station site in the emergency support task list, and a Tb-Tf difference table for each communication base station site in the support task list, and execute the support task based on the above two tables.

[0047] The present invention can achieve the following: (1) real-time monitoring of the emergency support personnel and the storage location of emergency supplies, and presenting their locations in real time in the system. (2) in the event of a major natural disaster, timely production of the best support path, rapid dispatch of existing resources and existing support personnel to meet the needs of timely and rapid power backup for multiple base stations, and immediate restoration of base station communications.

[0054] The present invention is described in further detail below with reference to the embodiments.

[0055] Those skilled in the art will understand that the following examples are intended to illustrate the present invention only and should not be construed as limiting the scope of the present invention. Where specific techniques or conditions are not specified in the examples, the techniques or conditions described in the literature in the art or in the product specifications were used. Materials or equipment used without manufacturer identification are commercially available conventional products.

[0056] The emergency communication support scheduling method based on backup power duration and travel time proposed in this invention is mainly based on the base station backup power duration data and the travel time of the maintenance personnel to the base station. The two time points are compared, and the communication base stations that need to be protected are comprehensively considered. The priority of the protection is evaluated and the final protection plan is output. The specific method is as follows:

[0057] Step 1: Obtain the emergency events and response levels that need to be protected. Based on the areas involved in the emergency events, determine the number and location distribution of communication base stations to be protected. At the same time, combined with the protection levels of the communication base stations, finally determine the list of communication base station sites to be protected as the emergency protection task list; establish a protection task list database to store the basic data of the communication base station sites to be protected;

[0058] Step 2: Establish a material reserve database, then query the emergency material reserve points in the area involved in the emergency incident, as well as the material reserve status of each reserve point, and determine whether the emergency material reserve status meets the emergency material reserve guarantee requirements for the emergency incident that needs to be guaranteed obtained in step 1;

[0059] The material reserve database includes information on the location of material storage, the type of material, the information on emergency material custodians, and the conditions for obtaining and using the material;

[0060] Step 3: Establish an emergency support personnel information database, then query the information of emergency support personnel in the area involved in the emergency event, and determine whether the emergency support personnel information meets the emergency support personnel protection requirements for the sudden emergency event that needs to be protected obtained in step 1;

[0061] Among them, the emergency support personnel information database includes basic personnel information, personnel location information and personnel's emergency skills;

[0062] Step 4: Based on the emergency support task list determined in step 1, query the location information of the emergency support material storage, the location information of the emergency support personnel, and the location information of the communication base station in the task list, calculate the travel time Tf to each target communication base station in the emergency support task list, and store it in the support task list database; the calculation process is as follows: Figure 1As shown, it is preferred to use existing map software to calculate the travel time Tf according to relevant means of transportation, and select the shortest time as the travel time Tf.

[0063] Step 5: Calculate the backup power time Tb of each base station in the proposed emergency support task list based on the backup power data information of each communication base station in the emergency support task list, and store it in the support task list database; the calculation process is as follows: Figure 2 shown.

[0064] Step 6: Based on the backup power time and the travel time of the base station, generate the optimal protection path map for each communication base station site in the emergency protection task list, as well as the corresponding emergency protection materials and emergency protection personnel, to form a protection plan for a single site; calculate the score of each communication base station site in the emergency protection task list, generate a score table for each communication base station site in the emergency protection task list, and store it in the protection task list database; based on the optimal protection path map, calculate the Tb-Tf difference table for each communication base station site in the protection task list, and store it in the protection task list database;

[0065] Step 7: Execution of the protection plan. Based on the importance of the event to be protected and the economic feasibility of the protection event, choose one of the following two strategies to implement the corresponding protection plan;

[0066] The first strategy is to calculate the ranking of the sites in the security task list based on their importance, and then implement the security plans in each security task list in descending order.

[0067] The second strategy is to sort by the time difference Tb-Tf, from small to large, and execute the support plans in each support task list in sequence.

[0068] In step one, the response levels for sudden emergency events include Level I, Level II, Level III, and Level IV. Specifically, the emergency response levels are usually determined based on existing published documents or defined by the units that ensure the needs. From high to low, they are mainly divided into: Level I (red), Level II (orange), Level III (yellow), and Level IV (blue). The activation standards are shown in Table 1.

[0069] Table 1 Emergency Response Levels

[0070]

[0071] The basic data of the communication base station site includes: base station name, communication equipment resource data involved in the base station, base station load data, base station code, base station location information, base station security level and base station coverage scenarios.

[0072] Among them, the communication equipment resource data involved in the base station mainly includes: equipment asset card, network access years, purchase price, operating hours, etc.

[0073] The location information of a base station includes longitude and latitude.

[0074] The security level of a base station is customized when the base station is built.

[0075] The base station covers scenarios including schools, public management departments, subways, airports, railway stations, docks, large shopping malls, large venues, hospitals, etc.

[0076] In step 2, the location information of material storage includes longitude, latitude, and specific storage address; the types of materials include backup batteries, generators, emergency kits, vehicles, satellite phones, walkie-talkies, and kayaks; the information of the person in charge of emergency materials includes name and contact information; the conditions for obtaining materials include the approval process and the person in charge.

[0077] In step 3, basic personnel information includes name, gender, ethnicity, age, affiliation, contact number, and emergency contact number;

[0078] Personnel location information is the real-time location information of personnel, which can be read in real time through mobile phone positioning or other positioning devices;

[0079] Emergency response skills include: diesel generator generation and troubleshooting, battery installation and troubleshooting, switching power supply installation and troubleshooting, and power cable routing and handling. Emergency support personnel performing support tasks must possess the relevant skills required for emergency support, matched to the specific emergency event.

[0080] In step 5, if the communication base station uses battery backup, the backup duration = battery pack capacity (Ah) multiplied by battery pack voltage (V) divided by device power (W) multiplied by power factor Q;

[0081] If the communication base station uses cloud-controlled oil generator backup power, the backup power duration is calculated based on the oil reserve of the oil generator;

[0082] If the communication base station uses both batteries and cloud-controlled oil generators for backup power, the backup time is the sum of the battery backup time and the cloud-controlled oil generator backup time.

[0083] In step 6, the specific method for calculating the score of each communication base station site in the emergency support task list is as follows:

[0084] If the communication base station site is a custom priority site, the communication base station site score is 100 points; otherwise, it is calculated according to the following formula:

[0085] The communication base station site score = the communication base station site scenario weight value score + the emergency material storage weight value score in the site's security plan + the communication base station site power backup time weight value score + the emergency support personnel travel time weight value score in the site's security plan.

[0086] The concept of the above calculation method is shown in Table 2.

[0087] Table 2

[0088]

[0089] Communication base station site scenario weights: Based on the degree of social impact of the protected site, the level of the site to be protected is determined, and weights are assigned to it based on its importance; details are shown in Table 3.

[0090] Table 3

[0091]

[0092] The weight of emergency material reserves in the site support plan: Based on the demand for emergency materials corresponding to the emergency event, the reserve situation of the materials is analyzed, and weights are assigned based on the adequacy of the reserves; the details are shown in Table 4.

[0093] Table 4

[0094]

[0095] Weight of the backup power supply duration of the communication base station site: Based on the backup power supply duration of the base station and the importance of the corresponding protection requirements, weights are assigned to determine the priority of the protection site. The shorter the backup power supply duration, the higher the level and the greater the score; the details are shown in Table 5.

[0096] Table 5

[0097]

[0098] The weight of the travel time of emergency personnel in the site support plan: According to the emergency personnel to be selected, the travel time to the site to be supported is used to assign corresponding permissions and score them. The optimal support candidate is determined through this plan. The shorter the travel time, the more suitable the personnel for support and the higher the corresponding score; the details are shown in Table 6.

[0099] Table 6

[0100]

[0101] In step seven, if the time difference calculated by the second strategy is within plus or minus 10 minutes, the protection plan is executed according to the first strategy.

[0102] 1) Determine the safeguard dispatching decision point: The backup power duration is denoted as Tb, and the travel time is denoted as Tf. When a sudden natural disaster occurs, an emergency event is triggered and the emergency response is initiated. The time point when Tf = Tb is the dispatching decision time point for this event. The emergency dispatching and command department should make an emergency dispatching decision before this emergency dispatching time point at the latest. From the perspectives of economy and timeliness, making a dispatching decision at this time point and implementing the emergency plan is the optimal dispatching plan, as shown in Figure 3 as follows.

[0103] 2) The time period when Tf < Tb is the emergency preparation time point. During this time period, emergency support personnel should promptly make emergency preparations, quickly formulate an emergency support plan, confirm the emergency content in a timely manner, clarify the emergency objectives, and identify the personnel, materials, vehicles, etc. for implementing the emergency support tasks to form the best emergency support plan.

[0104] 3) When an emergency support event occurs, if Tb = 0 or Tf > Tb, the emergency department needs to make an emergency decision immediately, and at the same time, activate other emergency plans or seek other emergency support channels, such as cross-region support, cross-unit support, etc.

[0105] Application Example

[0106] A magnitude 6.7 earthquake occurred in a certain city, resulting in a power outage in a township and the entire township being in a state of communication disconnection. A total of 28 communication base stations in the earthquake-stricken area need to be promptly safeguarded.

[0107] Generate a safeguard plan for a single site according to this invention and execute the safeguard plan according to the first strategy. The safeguard execution order for 28 sites is shown in Table 7.

[0108] Table 7

[0109]

[0110] Execute the safeguard plan according to the second strategy. The safeguard execution order for 28 sites is shown in Table 8.

[0111] Table 8

[0112]

[0113] In this example, priority is given to safeguarding importance, and the first strategy is selected for safeguarding, optimizing the emergency support dispatching, saving safeguard resources to the greatest extent. The safeguard resources are saved by approximately 20%, the safeguard cost is saved, and the safeguard cost is saved by approximately 30%, greatly improving the safeguard effect.
