BRIEF DESCRIPTION OF THE DRAWINGS The technical solutions in the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative work are within the scope of the present invention.

The International Telecommunication Union Telecommunication Standardization Sector (ITU) has introduced in its Recommendation K.52 guidelines for compliance with the limits of personal exposure in electromagnetic fields, and introduces EMF (Electromagnetic Fields). Electromagnetic radiation) A method of evaluating the exposure of a cartridge and providing a calculation for calculating the intensity of electromagnetic radiation at a location (also known as "power density"). The embodiment of the present invention provides a method and a mobile terminal capable of facilitating the user to evaluate the current position of the electromagnetic radiation of the base station antenna at any time based on the ITU-T Recommendation K.52.

Referring to Figure 1, there is shown a flow diagram of a first embodiment of a method of assessing the safety of electromagnetic radiation in accordance with the present invention. The executor of the method embodiment of FIG. 1 may be a mobile terminal such as a mobile phone that can implement functions such as making a call, sending and receiving text messages, and wireless Internet access. The method flow of Figure 1 includes:

Step S11, acquiring a radiation power value of the base station antenna at the current location, and a base station antenna and a current location. - - Relative location information.

The current location refers to the location where the current moment of the mobile terminal of the embodiment is executed. The radiated power value is also called "the signal strength received by the mobile phone". This value is one of the necessary parameters for the normal communication of the mobile phone. Generally, the ordinary mobile phone does not directly provide the user interface to display the parameter, and the smart phone generally provides the user interface to display the parameter. The parameter, for example, shows: "The current signal strength is -56dBm"; therefore, when the mobile phone of this embodiment needs to evaluate the electromagnetic radiation safety of the current position, the radiant power value of the base station at the current position can be directly queried by the query procedure.

The relative position information of the base station antenna and the current position includes: a linear distance between the base station antenna and the current position, and an angle of the base station; the relative position information is calculated or directly obtained by other information obtained, for example:

In some embodiments, the relative position information of the base station antenna and the current position is obtained according to the user input. As shown in FIG. 2, the user can estimate the horizontal distance between the base station antenna (the illustrated position Α) and the current position of the user (the illustrated position Β). X and vertical distance h, then input the estimated horizontal distance X and vertical distance h to the information input interface provided by the mobile phone, then the mobile phone can calculate the base station antenna and the current position according to the preset formula: r ² = h ² + x ² The straight line distance r, and the angle Θ of the base station antenna is calculated according to the preset formula: Θ =tan ⁴ (x/h). It should be noted that if the vertical distance h in the above formula refers to the distance between the base station antenna and the ground, then the above formula can also consider the height hi of the mobile phone from the ground, that is, replace h in the above formula with (h-hl). The height hi can be input by the user, or preset to 1. 6m or preset to other values.

2 is a case where the user is in the ground, and FIG. 3 can be referred to when the user is on the floor. In this scenario, the user can evaluate the height h of the base station antenna (position A in the illustration), the horizontal distance X of the base station antenna from the current position of the user (position B in the figure), and the height hi of the floor, when the mobile phone receives When the user types these evaluation values through the provided input interface, the mobile phone can according to r ² = ( h-hl ) ² + X ² , the angle of the antenna e

Calculate the linear distance r between the base station antenna and the current position and the angle of the base station antenna. Of course, the height of the mobile phone from the top surface of the floor can be further considered in the above formula.

In some embodiments, the relative position information of the base station antenna and the current location may be acquired by the base station. These embodiments mean that the base station can set certain location parameters to indicate the base station antenna and the mobile phone. - The relative position information of the current location; then, after receiving the request of the mobile phone for obtaining the relative location information, the base station can assist the positioning function, such as GPS (Global Positioning System), determining the base station antenna and the mobile phone Relative position information of the current location and sent to the phone via the location parameter.

In some embodiments, the relative position information of the base station antenna and the current location may also be obtained by the user's movement relative to the base station.

As shown in Fig. 4, the horizontal distance between the base station antenna and the current position of the user is difficult to evaluate due to the user, and the evaluation accuracy is poor. Thus the user can move relative to the base station antenna (position A in the illustration), for example horizontally towards the base station antenna or away from the base station antenna, and input the predicted base station antenna height h and the relative base station antenna movement to the handset. The distance x2, when the mobile phone receives the information, can calculate x2 according to the radiation power values of the two points before and after the recorded movement (position B and position C in the figure), and then calculate the relative according to the calculation methods of the previous two embodiments. Location information (rl or r2, θ 1 or Θ 2 ).

Further, step S11 may also acquire type information of the antenna and/or current scene information. The type information of the antenna includes: an omnidirectional antenna or a directional antenna; the current scene information includes: a wilderness scene, a roof scene, an inter-group scene, an indoor scene, or a street scene. This information can be entered by the user or provided to the user with the option of the information, which is selected by the user.

Step S12: Convert the radiant power value of the base station antenna at the current position to the electromagnetic radiation intensity of the base station antenna at the current position according to the information acquired in step S11. Here, it is mainly based on the evaluation method of electromagnetic radiation introduced in the ITU-T Recommendation K.52.

In step S12, the radiation power value of the base station antenna at the current position may be converted into the electromagnetic radiation intensity of the base station antenna at the current position according to the relative position information of the base station antenna and the current position. Or, based on this, the type information of the antenna and/or the current scene information can be further considered to further obtain a more accurate electromagnetic radiation intensity.

Step S13, comparing the electromagnetic radiation intensity obtained in step S12 with the electromagnetic radiation limit line to determine the safety of the electromagnetic radiation at the current position.

Wherein, the electromagnetic radiation limit line which is compared with the electromagnetic radiation intensity may be the electromagnetic radiation limit line specified by WHO, ICNIRP and IEEE, or the electromagnetic radiation limit line established by each region, or according to the user input proportional coefficient The electromagnetic radiation limit line is reduced by 1/n (n is a positive integer, - - For example, the default electromagnetic radiation limit line after n = 10). Further, the electromagnetic radiation limit lines include: worker work limit lines, public limit lines, and the like.

Evaluating the electromagnetic radiation safety of the current location may include: non-safety, worker work safety, public safety, user-set safety, or non-user-set safety. For example: When the electromagnetic radiation intensity is greater than the worker's working limit line, the evaluation is non-safe; when the electromagnetic radiation intensity is less than the worker's working limit line and greater than the public limit line, the evaluation is the worker's working limit line; when the electromagnetic radiation intensity is less than When the public limit line is used, the assessment is public safety; when the electromagnetic radiation intensity is greater than the 1/n electromagnetic radiation limit line set by the user, the evaluation is non-user-set safety; when the electromagnetic radiation intensity is less than the user-set When the 1/n electromagnetic radiation limit line is used, the safety set by the user is evaluated.

Further, please refer to FIG. 5, which is a schematic flowchart of an embodiment of step S13, where the step is performed.

S13 includes:

Step S131: Obtain area information of the current location.

Among them, the regional information of the current location can be obtained by means of GPS positioning, and the information of the region can be national information, or information such as provinces, continents, and cities.

Step S132: Obtain an electromagnetic radiation limit line of a region to which the current location belongs according to the area information. Step S133, comparing the electromagnetic radiation intensity with the acquired electromagnetic radiation limit line to determine the safety of the electromagnetic radiation at the current position.

In this embodiment, the radiation power value of the base station antenna at the current position is converted into the electromagnetic radiation intensity of the base station antenna at the current position, and the electromagnetic radiation intensity of the base station antenna at the current position is obtained, and the obtained electromagnetic radiation intensity and the preset are obtained. The electromagnetic radiation limit lines are compared to determine the electromagnetic radiation safety at the current location. Since the radiant power of the base station antenna at the current location is a necessary parameter for the mobile terminal to communicate with each other, the mobile terminal capable of communicating can obtain the parameter. Therefore, the method of the embodiment of the present invention can be used in a mobile terminal such as a mobile phone. It is easily realized, so that the user can quickly obtain the electromagnetic radiation safety information of the current location through the mobile terminal such as a mobile phone, and improve the transparency of the electromagnetic radiation intensity of the base station antenna.

Referring to Figure 6, a flow diagram of a second embodiment of a method of assessing the safety of electromagnetic radiation of the present invention is shown. Figure 6 differs from Figure 1 in that it also includes:

Step S14, displaying the electromagnetic radiation safety of the current location, and/or, performing an alarm according to the electromagnetic radiation safety of the current location. The alarm includes: prompting the user to leave, prompting the user to not exceed the predetermined value in the current location or prompting the user to secure the current location. For example: When the assessed security is non-secure, the user is prompted to leave; when the assessed security is the worker's work safety, the user is prompted not to exceed 8 hours in the current location.

Further, the alarm may be performed by sending the alarm information to other electronic devices of the user through Bluetooth or infrared technologies, and the alarm is not limited.

In this embodiment, the display and/or the alarm can enable the user to quickly understand the electromagnetic radiation safety of the current location, and avoid the user being in an environment with low electromagnetic radiation safety, thereby avoiding the user being subjected to high-intensity electromagnetic radiation mapping, which is beneficial to the user. To ensure the health of the user. An application of this embodiment is to monitor the electromagnetic radiation safety of the location at any time when the mobile phone is in normal standby, and prompt the user to leave as soon as possible after detecting low security, such as non-security or worker work safety.

Please refer to FIG. 7, which is a schematic flow chart of a third embodiment of the method for estimating the safety of electromagnetic radiation of the present invention. The method flow of Figure 7 includes:

Step S101: Obtain a base station radiation power value of a current location of the mobile phone.

Wherein, when the user's request for determining the electromagnetic radiation security of the current location is received, step S101 is performed, or step S101 is periodically performed. Since the base station radiated power value of the current location of the mobile phone is an essential parameter for the mobile phone to communicate, there is a record in the mobile phone; therefore, step S101 can directly query the recorded base station radiated power value by using the query program.

In step S102, the user selects the mode of inputting the parameter. If the user selects manual input, the process goes to step S103. If the user selects automatic acquisition, the process goes to step S104.

Step S103, the user inputs the horizontal distance, the height of the base station antenna, the height of the base station, selects the type of the antenna and the type of the scene, and proceeds to step S105.

The user input horizontal distance, the height of the base station antenna, and the height of the base are corresponding to the scenarios described in FIG. 2 and FIG. 3, and the relative position information of the user and the base station antenna is calculated according to the user input horizontal distance, the height of the base station antenna, and the height of the base station.

Step S104: Acquire and input through relative movement by the base station or the user, and go to step S105. Step S104 is to obtain relative position information of the user and the base station antenna by using the base station, or acquire the relative position information of the user and the base station by using the scenario of FIG. 4 . It should be noted here that step S104 is only partial automatic acquisition, and some parts require user input or selection, for example: base station antenna in FIG. - The height of the antenna, the type of antenna, and the type of scene the person is in.

Step S105, evaluating the electromagnetic radiation field strength of the current environment, and proceeding to step S106.

Step S201: Query the embedded GPS or base station positioning system settings, and query the country.

Wherein, when it is required to evaluate the electromagnetic radiation safety of the current location, step S201 is performed.

Step S202, querying the country limit line and the 1/n field strength limit line, and providing step S106. Wherein, according to the national information queried in step S201, the electromagnetic radiation limit line of the country is queried; if the country does not have the electromagnetic radiation limit line, the internationally accepted ICNIRP limit line is used. Here, if the user sets the 1/n parameter, the 1/n field strength limit line is also obtained.

Step 106, whether the limit line is exceeded.

The electromagnetic radiation intensity of step S105 is compared with the limit line of step S202 to evaluate the electromagnetic radiation safety.

Step S107, displaying and/or alarming.

Same as step S14.

The terminal that executes the above method flow is described below corresponding to the above method flow.

The obtaining unit 11 is configured to obtain a radiation power value of the base station antenna at the current location and relative position information of the base station antenna and the current location.

The current location refers to the location where the mobile terminal 1 is currently located. The radiated power value is also called "the signal strength received by the mobile phone". This value is one of the necessary parameters for the normal communication of the mobile phone. Generally, the ordinary mobile phone does not directly provide the user interface to display the parameter, and the smart phone generally provides the user interface to display the parameter. The parameter, for example, shows: "The current signal strength is -56dBm". When the mobile phone of this embodiment needs to evaluate the electromagnetic radiation safety of the current location, the radiant power value of the base station at the current location can be directly queried by the query procedure.

The relative position information of the base station antenna and the current position includes: a linear distance between the base station antenna and the current position, and an angle of the base station.

X and the vertical distance h, then the mobile phone can calculate the linear distance r between the base station antenna and the current position according to the preset formula: r ² = h ² + x ² , and according to the preset formula: e ^an—^x/ h), calculate the angle Θ of the base station antenna. It should be noted that if the vertical distance h in the above formula refers to the distance between the base station antenna and the ground, then the above formula can also consider the height hl of the mobile phone from the ground, that is, replace h in the above formula with (h-hl). The height hi can be input by the user, or preset to 1. 6m or preset to other values.

2 is a case where the user is in the ground, and FIG. 3 can be referred to when the user is on the floor.

In some embodiments, the relative location information of the base station antenna and the current location may be obtained by the base station. These embodiments mean that the base station can set certain location parameters to indicate the relative location information of the base station antenna and the current location of the mobile phone.
