Description

TECHNICAL FIELD

[0002] The alarm refers to an apparatus for issuing an alarm signal, which is widely used in perimeter protection, urban security, villa wall, community perimeter, factory warehouse, company, school, family, warehouse, resource, oil and many other fields. When the alarm is used for urban security, the alarm will issue civil air defense alarm signals for early warning, alarm and alarm cancellation.

[0003] In related technologies, when the alarm is used for urban security, in order to enable the alarm terminal device to cover the entire city, the alarm terminal device generally uses a high-power device, and needs to be erected on the top of a high-rise building or in a flat, unobstructed and power environment, thereby increasing the coverage range of the alarm terminal device.

[0004] In view of the above related technologies, the following defects are found: when the alarm terminal device covers the entire city, since the alarm terminal device generally uses a high-power device, the volume of the alarm terminal device is relatively large, the alarm terminal device is easily limited by various factors during installation, and the sound is fan-shaped propagation, which causes adjacent two alarm terminal devices to easily have a coverage dead angle, thereby making the alarm terminal device not easy to effectively cover the entire city, and further reducing the alarm coverage rate of the entire city, which still has room for improvement.

[0130] The prevailing wind influence adjustment method is used to analyze and process the alarm initial installation position point, the prevailing wind direction influence position offset direction information and the prevailing wind force influence position offset value, so as to form a prevailing wind influence adjustment position point, and the prevailing wind influence adjustment position point is used as the alarm preliminary installation position point, so that the obtained alarm preliminary installation position point is affected by the prevailing wind of the current city, thereby improving the accuracy of the obtained alarm preliminary installation position point.

[0131] In Figure 1 In order to further ensure the rationality of the alarm influence position point, further separate analysis and calculation of the alarm influence position point is required, which is specifically described in the steps shown in Figure 3 .

[0132] Referring to Figure 3 , the alarm influence position confirmation method is used to analyze and process the overall building layout information of the current city to form an alarm influence position point, including the following steps:

[0133] Step S410, according to the preset building height feature, the building height influence position point is selected from the overall building layout information of the current city.

[0134] The building height feature refers to a feature for indicating the height of the building, and the building height feature is obtained by querying a database storing the building height feature.

[0135] The building height influence position point refers to the position point of the installation position of the electro-acoustic alarm device after being affected by the height of the building.

[0136] The building height feature is used to analyze and select the building height influence position point from the overall building layout information of the current city, thereby facilitating subsequent use of the building height influence position point.

[0137] Step S420, according to the preset regional scene type feature, the regional scene type influence position point is selected from the overall building layout information of the current city.

[0138] The regional scene type feature refers to a feature for indicating the specific use type of the region, and the regional scene type feature includes central business district, administrative district, industrial district, cultural and entertainment district, residential district, warehouse and wharf district, recreation district and suburb, etc.

[0139] The regional scene type influence position point refers to the position point of the installation position of the electro-acoustic alarm device after being affected by the specific use type of the region.

[0140] The region scene type influence position points are selected from the current city overall house layout information by the region scene type features, so that the region scene type influence position points are conveniently used subsequently.

[0141] For example, because the noise of the industrial area is larger than that of the residential area and the suburb, the region scene type influence position points in the industrial area are more than those in the residential area and the suburb.

[0142] In step S430, the house height influence position points and the region scene type influence position points are taken as the alarm influence position points.

[0143] The house height influence position points and the region scene type influence position points are taken as the alarm influence position points, so that the alarm influence position points are affected by the house height and the region scene type near the installation position, and the accuracy of the obtained alarm influence position points is improved, and the alarm coverage rate of the whole city is finally improved.

[0144] In Figure 1 In order to further ensure the rationality of the alarm final installation position points, further separate analysis and calculation of the alarm final installation position points are needed, and the steps are shown in Figure 4 The steps are described in detail.

[0145] Referring to Figure 4 According to the preset alarm final installation position confirmation method, the alarm preliminary installation position points and the alarm influence position points are analyzed and processed to form the alarm final installation position points for installing the electro-acoustic alarm device, and the steps include the following steps:

[0146] In step S510, it is judged whether the alarm influence position points are region scene type influence position points. If yes, step S520 is executed; if no, step S530 is executed.

[0147] The alarm influence position points are region scene type influence position points, so that it is convenient to judge whether the installation position of the electro-acoustic alarm device needs to be further analyzed subsequently.

[0148] In step S520, the alarm influence position points are replaced to the alarm preliminary installation position points, and the alarm preliminary installation position points and the alarm influence position points which are not replaced are taken as the alarm final installation position points.

[0149] When the alarm influence location point is a region scene type influence location point, it is not necessary to further analyze the installation position of the electro-acoustic alarm device, so the alarm influence location point directly replaces the alarm preliminary installation location point, and the alarm preliminary installation location point and the alarm influence location point which are not replaced are used as the alarm final installation location point, thereby improving the accuracy of the obtained alarm final installation location point.

[0150] In step S530, the distance value between the alarm preliminary installation location point and the alarm influence location point is calculated according to the alarm preliminary installation location point and the alarm influence location point, and is used as the alarm influence actual distance value.

[0151] The alarm influence actual distance value refers to the actual distance value between the preliminary installation location point and the alarm influence location point.

[0152] When the alarm influence location point is not a region scene type influence location point, it is necessary to further analyze the installation position of the electro-acoustic alarm device, so the distance value between the alarm preliminary installation location point and the alarm influence location point is calculated, thereby the distance value between the alarm preliminary installation location point and the alarm influence location point is used as the alarm influence actual distance value, and the alarm influence actual distance value is used for subsequent use.

[0153] In step S540, the distance influence adjustment location point is obtained according to the judgment result of whether the alarm influence actual distance value is greater than the preset alarm influence reference distance value, and the distance influence adjustment location point is used as the alarm final installation location point.

[0154] The alarm influence reference distance value refers to the reference distance value between the preliminary installation location point and the alarm influence location point, and the alarm influence reference distance value is obtained from a database in which the alarm influence reference distance value is stored.

[0155] The distance influence adjustment location point is obtained according to the judgment result of whether the alarm influence actual distance value is greater than the preset alarm influence reference distance value, and the distance influence adjustment location point is used as the alarm final installation location point, thereby improving the accuracy of the obtained alarm final installation location point.

[0156] In Figure 4 In step S540 shown in FIG. 8, in order to further ensure the rationality of the distance influence adjustment location point, it is necessary to further analyze and calculate the distance influence adjustment location point, and the specific steps are described in detail as follows. Figure 5

[0157] Referring to Figure 5 ​According to the judgment result of whether the alarm influence actual distance value is greater than the preset alarm influence reference distance value, the distance influence adjustment position point is analyzed and acquired, including the following steps:

[0158] In step S541, it is judged whether the alarm influence actual distance value is greater than the preset alarm influence reference distance value. If yes, step S542 is executed; if no, step S544 is executed.

[0159] The alarm influence actual distance value is greater than the preset alarm influence reference distance value, so that it is judged whether the distance influence adjustment position point needs to be further analyzed.

[0160] In step S542, the influence house height value is acquired.

[0161] The influence house height value refers to the height value of the house which influences the installation position of the electro-acoustic alarm device. The influence house height value is acquired from the database in which the influence house height values are stored.

[0162] When the alarm influence actual distance value is greater than the preset alarm influence reference distance value, it is not easy to directly replace the alarm influence position point with the alarm preliminary installation position point, and the distance influence adjustment position point needs to be further analyzed, so the influence house height value is acquired.

[0163] In step S543, according to the corresponding relationship between the alarm influence actual distance value, the influence house height value and the preset house height influence adjustment position point, the house height influence adjustment position point corresponding to the alarm influence actual distance value and the influence house height value is analyzed and acquired, and the house height influence adjustment position point is taken as the distance influence adjustment position point.

[0164] The house height influence adjustment position point refers to the position point which is adjusted after being influenced by the house height. The house height influence adjustment position point is acquired from the database in which the house height influence adjustment position points are stored.

[0165] The house height influence adjustment position point is analyzed and acquired according to the alarm influence actual distance value and the influence house height value, and the house height influence adjustment position point is taken as the distance influence adjustment position point, so that the accuracy of the acquired distance influence adjustment position point is improved.

[0166] In step S544, the alarm influence position point is replaced with the alarm preliminary installation position point and taken as the distance influence adjustment position point.

[0167] Among them, when the actual distance value of the alarm impact is not greater than the preset alarm impact benchmark distance value, it means that no further analysis of the distance impact adjustment position point is required at this time, so the alarm impact position point replaces the alarm initial installation position point and serves as the distance impact adjustment position point, thereby improving the accuracy of the obtained distance impact adjustment position point.

[0168] exist Figure 1 After step S600, in order to further ensure the rationality of sending the electric alarm control information to the electric alarm device installed at the final installation location of the alarm, it is necessary to perform further separate analysis and calculation after sending the electric alarm control information to the electric alarm device installed at the final installation location of the alarm, specifically through Figure 6 The steps shown are explained in detail.

[0169] Reference Figure 6 The steps after sending the electric alarm control information to the electric alarm device installed at the final installation location of the alarm include the following steps:

[0170] Step S610: Obtain current weather information.

[0171] The current weather information refers to the weather condition information of the current city at the current time, and the current weather information is obtained by querying the weather monitoring database of the current city.

[0172] Step S620: Determine whether the current weather information is the preset charging permission weather information. If yes, execute step S630; if no, execute step S640.

[0173] The charging permission weather information refers to weather condition information that can assist charging. The charging permission weather information is obtained by querying from a database that stores the charging permission weather information.

[0174] By determining whether the current weather information is preset charging permission weather information, it is determined whether the current weather condition can assist in charging the electric sound alarm device.

[0175] Step S630 , sending the preset DC power off control information and the preset solar charging control information to the electric sound alarm device.

[0176] The DC power outage control information refers to control information for controlling the DC power supply to be cut off, and the DC power outage control information is retrieved from a database storing DC power outage control information. The solar charging control information refers to control information for controlling the electric alarm device to be solar-powered and is retrieved from a database storing solar charging control information.

[0177] If the current weather information is the preset charging permission weather information, it indicates that the current weather condition can assist the charging of the electric sound alarm device at this time, and therefore the preset direct current power off control information and the preset solar charging control information are sent to the electric sound alarm device, so as to control the direct current power to be powered off and control the electric sound alarm device to be charged by solar energy, thereby improving the utilization rate of energy and prolonging the use time.

[0178] In step S640, the preset direct current power charging control information and the preset solar power off control information are sent to the electric sound alarm device.

[0179] The direct current power charging control information refers to control information for controlling the electric sound alarm device to be charged by direct current power, and the direct current power charging control information is obtained from a database storing the direct current power charging control information. The solar power off control information refers to control information for controlling the electric sound alarm device to stop charging by solar energy, and the solar power off control information is obtained from a database storing the solar power off control information.

[0180] If the current weather information is not the preset charging permission weather information, it indicates that the current weather condition cannot assist the charging of the electric sound alarm device at this time, and therefore the preset direct current power charging control information and the preset solar power off control information are sent to the electric sound alarm device, so as to control the electric sound alarm device to be charged by direct current power and control the electric sound alarm device to stop charging by solar energy, thereby prolonging the use time.

[0181] In Figure 6 After step S640 shown in FIG. 6, in order to further ensure the rationality after the preset direct current power charging control information and the preset solar power off control information are sent to the electric sound alarm device, it is necessary to make further separate analysis and calculation after the preset direct current power charging control information and the preset solar power off control information are sent to the electric sound alarm device, which is specifically described by the steps shown in Figure 7 .

[0182] Referring to Figure 7 , the steps after the preset direct current power charging control information and the preset solar power off control information are sent to the electric sound alarm device include the following steps:

[0183] In step S641, it is judged whether the direct current power off control information and the solar charging control information are received. If yes, step S641 is executed, and if no, step S642 is executed.

[0184] By judging whether the direct current power off control information and the solar charging control information are received, it is judged whether the charging mode of the electric sound alarm device at the current time is solar charging.

[0185] When the DC power outage control information and the solar charging control information are not received, it indicates that the charging mode of the electric acoustic alarm device at the current time is solar charging, so step S641 is executed.

[0186] In step S642, the current time point is obtained.

[0187] The current time point refers to the time information of the current time, which is obtained by querying the database of the current time.

[0188] When the DC power outage control information and the solar charging control information are received, it indicates that the charging mode of the electric acoustic alarm device at the current time is not solar charging, so the current time point is obtained to facilitate subsequent use.

[0189] In step S643, the time period between the current time point and the solar power outage time point is analyzed and calculated as the solar power outage actual time period.

[0190] The solar power outage time point is defined as the time point when the solar power outage control information is received, which is obtained by querying the database when the solar power outage control information is received.

[0191] The solar power outage actual time period refers to the actual duration of stopping using solar energy for charging. The time period between the current time point and the solar power outage time point is analyzed and calculated, and the time period is taken as the solar power outage actual time period, to facilitate subsequent use of the solar power outage actual time period.

[0192] In step S644, it is determined whether the solar power outage actual time period is greater than the preset solar power outage reference time period. If yes, step S645 is executed, and if no, step S642 is executed.

[0193] The solar power outage reference time period refers to the reference duration of stopping using solar energy for charging, which is obtained by querying the database where the solar power outage reference time period is stored.

[0194] By determining whether the solar power outage actual time period is greater than the preset solar power outage reference time period, it is determined whether the DC power source still has power to charge the electric acoustic alarm device.

[0195] When the solar power outage actual time period is not greater than the preset solar power outage reference time period, it indicates that the DC power source has power to charge the electric acoustic alarm device, so step S642 is executed.

[0196] Step S645, send the preset low power alarm information to the terminal held by the manager.

[0197] The low power alarm information refers to the alarm information for prompting the low power of the DC power supply, and the low power alarm information is obtained from a database storing the low power alarm information.

[0198] When the actual solar power outage time period is greater than the preset solar power outage reference time period, it indicates that the DC power supply does not have power to charge the electric sound alarm device at this time, and therefore the preset low power alarm information is sent to the terminal held by the manager, so that the manager can understand the state of the electric sound alarm device in time, and then supplement the power of the electric sound alarm device in time, so that the electric sound alarm device can always be in a working state, and finally the purpose of improving the alarm coverage rate of the entire city is achieved.

[0199] Further, in order to improve the alarm coverage rate of the entire city, the following steps are further included after step S645. Obtain an abnormal position point corresponding to the sending of the preset low power alarm information; according to the corresponding relationship between the abnormal position point and the preset peripheral installation position point, analyze and obtain the peripheral installation position point corresponding to the abnormal position point; according to the peripheral installation position point and the abnormal position point, analyze and calculate the distance value between the peripheral installation position point and the abnormal position point as the peripheral installation distance value; according to the corresponding relationship between the peripheral installation distance value and the preset power adjustment information, analyze and obtain the power adjustment information corresponding to the peripheral installation distance value, and send the power adjustment information to the electric sound alarm device at the peripheral installation position point.

[0200] The peripheral installation position point refers to a position point located around the abnormal position point and used for installing the electric sound alarm device, and the peripheral installation position point is obtained from a database storing the peripheral installation position point. The peripheral installation distance value refers to the distance value between the peripheral installation position point and the abnormal position point, and the power adjustment information refers to the adjustment information for adjusting the power of the electric sound alarm device located at the peripheral installation position point, and the power adjustment information is obtained from a database storing the power adjustment information. By obtaining the abnormal position point, analyzing the peripheral installation position point from the abnormal position point, analyzing and calculating the distance value between the peripheral installation position point and the abnormal position point and taking the distance value as the peripheral installation distance value, analyzing and obtaining the power adjustment information from the peripheral installation distance value, and sending the power adjustment information to the electric sound alarm device at the peripheral installation position point, the working power of the electric sound alarm device at the peripheral installation position point is adjusted, so that the electric sound alarm device at the peripheral installation position point covers the range covered by the electric sound alarm device at the abnormal position point when it works, thereby reducing the generation of dead angles and improving the alarm coverage rate of the entire city.

[0201] exist Figure 6 After step S630 or step S640 shown, in order to further ensure the rationality of sending the preset DC power supply power-off control information and the preset solar charging control information to the electric alarm device, or after sending the preset DC power supply charging control information and the preset solar power-off control information to the electric alarm device, it is necessary to perform further separate analysis and calculation after sending the preset DC power supply power-off control information and the preset solar charging control information to the electric alarm device, or after sending the preset DC power supply charging control information and the preset solar power-off control information to the electric alarm device, specifically through Figure 8 The steps shown are explained in detail.

[0202] Reference Figure 8 The steps after sending the preset DC power supply off control information and the preset solar charging control information to the electric alarm device, or after sending the preset DC power supply charging control information and the preset solar power off control information to the electric alarm device include the following steps:

[0203] Step S631, determine whether infrared remote control information is received. If yes, go to step S632; if not, go to step S634.

[0204] The infrared remote control information refers to the control information for infrared remote control of the electroacoustic alarm device, and the infrared remote control information is detected and acquired through an infrared remote control module preset on the electroacoustic alarm device.

[0205] By judging whether the infrared remote control information is received, it is judged whether the manager performs infrared remote control on the electric sound alarm device.

[0206] Step S632: Acquire wireless microphone demand information.

[0207] The wireless microphone demand information refers to the voice playback demand information received from the wireless microphone, and the wireless microphone demand information is detected and acquired by a wireless microphone receiving module preset on the electro-acoustic alarm device.

[0208] When the infrared remote control information is received, it indicates that the administrator is performing infrared remote control on the electric alarm device, so the wireless microphone demand information is obtained, thereby facilitating subsequent use of the wireless microphone demand information.

[0209] Step S633 , according to the correspondence between the wireless microphone demand information, the preset sound amplification demand information and the preset sound amplification control information, analyze and obtain the sound amplification control information corresponding to the wireless microphone demand information and the sound amplification demand information, and send the sound amplification control information to the electric sound alarm device.

[0210] The sound amplification demand information is demand information for amplifying the received wireless microphone demand information, and is obtained from a database in which sound amplification demand information is stored.

[0211] The sound amplification control information is control information for controlling the electric sound alarm device to amplify the received wireless microphone demand information. The sound amplification control information is obtained from a database in which sound amplification control information is stored.

[0212] The sound amplification control information is obtained by analyzing the wireless microphone demand information and the sound amplification demand information, and is sent to the electric sound alarm device, so that the electric sound alarm device plays the wireless microphone demand information, thereby improving the utilization rate of the electric sound alarm device.

[0213] In step S634, the preset sleep control information is output to the electric sound alarm device.

[0214] The sleep control information is control information for controlling the electric sound alarm device to sleep, and is obtained from a database in which sleep control information is stored.

[0215] When the infrared remote control information is not received, it indicates that the manager does not control the electric sound alarm device by infrared remote control at this time, so the preset sleep control information is output to the electric sound alarm device, thereby controlling the electric sound alarm device to sleep and prolonging the use time of the electric sound alarm device.

[0216] After step S634 shown in Figure 8 , in order to further ensure the rationality after the preset sleep control information is output to the electric sound alarm device, further separate analysis and calculation are required after the preset sleep control information is output to the electric sound alarm device, which is specifically described by the steps shown in Figure 9 .

[0217] Referring to Figure 9 , the steps after the preset sleep control information is output to the electric sound alarm device include the following steps:

[0218] In step S6341, it is determined whether wireless remote control demand information is received. If yes, step S6342 is performed; if no, step S6343 is performed.

[0219] The wireless remote control demand information is demand information for wirelessly remotely controlling and playing the electric sound alarm device, and is obtained by detecting a wireless remote control receiving module preset on the electric sound alarm device.

[0220] By determining whether the wireless remote control demand information is received, it is determined whether the wireless remote control demand information needs to be played.

[0221] Step S6342, according to the preset remote control analysis method to analyze and process the wireless remote control demand information to form wireless remote control information, and send the wireless remote control information to the electric sound alarm device.

[0222] Wherein, the remote control analysis method refers to the method for analyzing the wireless remote control demand information, and the remote control analysis method is obtained from the database storing the remote control analysis method.

[0223] Wireless remote control information refers to the control information for playing back the control of the wireless remote electric sound alarm device.

[0224] When receiving the wireless remote control demand information, it means that the wireless remote control demand information needs to be played at this time, so the remote control analysis method is used to analyze and process the wireless remote control demand information, thereby forming the wireless remote control information, and sending the wireless remote control information to the electric sound alarm device, and then controlling the electric sound alarm device to play the wireless remote control demand information.

[0225] Step S6343, jump to step S634.

[0226] Wherein, when no wireless remote control demand information is received, it means that the wireless remote control demand information does not need to be played at this time, so jump to step S634.
