In one embodiment, the step of acquiring the self-information of the user is performed when the environment information conforms to any early warning source. Alternatively, the user's own information is acquired at the time of acquiring the environment information, that is, the step of acquiring the user's own information is executed at the time of executing the step of acquiring the environment information. For example, as shown in fig. 2, the near electricity warning method includes the following steps: acquiring environmental information; and judging whether the environmental information accords with any early warning source, if so, acquiring the self information of the user, then judging whether the self information accords with the preset early warning condition of the near-electricity position, and if so, giving an alarm. For example, when any early warning source is detected, the self information of the user is acquired; and then, alarming when the self information is judged to accord with the preset near-electricity position early warning condition. This has the advantage of saving power consumption and thus better providing longer term safety protection. One example is a near-electricity warning method, which includes the following steps: presetting a path range and a plurality of early warning sources in the path range; acquiring environment information according to a preset path range; alarming when the environment information is judged to accord with the preset near-electricity environment early warning condition; wherein, judge and report to the police when environmental information accords with and presets nearly electric environment condition, specifically include the following step: and polling the plurality of early warning sources in the preset path range, and giving an alarm when the environmental information accords with any early warning source, so that the polling comparison alarm efficiency can be greatly improved, and when the environmental information of a user accords with any early warning source in the preset path range, the alarm can be given in time or even early warning is given in advance, and the method is particularly suitable for fixed path patrol.
For example, before obtaining the self-information of the user, the near-electricity early warning method further includes the steps of: positioning labels are respectively arranged on the safety helmet and the identity card; the acquiring of the self information of the user specifically comprises acquiring the self information of the user through a positioning label of the safety helmet and a positioning label of the identity card respectively; for another example, before obtaining the self-information of the user, the near-electricity early warning method further includes the steps of: setting a positioning label on the mobile phone; the method for acquiring the self-information of the user further comprises the step of acquiring the self-information of the user through a positioning label of the mobile phone.
For another example, before obtaining the self-information of the user, the near-electricity early warning method further includes the steps of: the method comprises the following steps that a safety helmet and an identity card are respectively provided with a near-electricity early warning device, wherein the near-electricity early warning device comprises a controller, a near-electricity early warning chip and an ultra-wideband (UWB) chip, and the near-electricity early warning chip and the UWB chip are connected with the controller; the method comprises the steps of acquiring self information of a user, specifically acquiring the self information of the user through a near-electricity early warning device of a safety helmet and a near-electricity early warning device of an identity card respectively; for another example, before obtaining the self-information of the user, the near-electricity early warning method further includes the steps of: arranging a near-electricity early warning device on the mobile phone; the method for acquiring the self information of the user further comprises the step of acquiring the self information of the user through a near-electricity early warning device of the mobile phone. For example, the near-electricity early warning device or the mobile phone has a rechargeable battery, and the near-electricity early warning device acquires environmental information and gives an alarm when the environmental information meets preset near-electricity environmental early warning conditions.
For example, for overhead line tower construction, the acquiring of the self information of the user includes acquiring the self information of the user through a near-electricity early-warning device of a mobile phone, and specifically includes that a mobile phone sleeve type near-electricity early-warning device is sleeved on the mobile phone and matched with a mobile phone APP and GPS positioning to acquire the self information of the user; for another example, for the work of the transformer substation, the obtaining of the self information of the user includes comparing the multi-dimensional information of the near electric early warning device of the safety helmet, the near electric early warning device of the identity card and the near electric early warning device of the mobile phone through the near electric early warning device of the safety helmet, the near electric early warning device of the identity card and the near electric early warning device of the mobile phone respectively in cooperation with the server and the UWB positioning, so as to obtain the self information of the user.
In one embodiment, the self information further includes current dressing information; after self information of a user is acquired, the near-electricity early warning method further comprises the following steps: alarming when the self information is judged to accord with preset dressing early warning conditions; for example, when the current dressing information in the self information is judged to accord with the preset dressing early warning condition, an alarm is given. Therefore, when the user wears the protective clothing, whether the current dressing meets the dressing requirement can be automatically judged, and when the current dressing does not meet the dressing requirement, namely the current dressing information in the self information meets the preset dressing early warning condition, an alarm is given. For example, the preset dressing warning condition includes whether to activate at least two positioning tag devices, where each positioning tag device is configured to provide positioning tag information; the preset dressing early warning condition further comprises whether the distance between any two positioning label devices is larger than a preset distance threshold value, for example, the preset distance threshold value is 10 cm, 20 cm, 30 cm or 60 cm, the three-point three-dimensional positioning can be well realized through the enough preset distance threshold value, the positioning precision is favorably improved, and the problem that the positioning precision is reduced due to the fact that a single positioning label device is shielded is solved. For another example, the preset dressing early warning condition further includes whether positioning label devices in a plurality of specific positions are worn in place, for example, whether helmets, protective clothing, gloves and/or shoes are worn in place, which is beneficial to further reducing the work risk of users, and multi-point positioning avoids the problem of positioning accuracy reduction caused by shielding, and the density of the positioning base station does not need to be increased. For example, RFID tags are provided on a helmet, an identification card (i.e., a work card), a work suit, and/or a safety belt, respectively.
For example, as shown in fig. 3, a user's safety helmet, work card, work clothes, safety belt, gloves, and insulating shoes are respectively provided with a positioning tag or a proximity sensor for providing positioning tag information, and each positioning base station determines whether the user is located in a safety area outside an electronic fence according to the wireless positioning tag information, and gives an alarm when the user leaves the safety area and enters the electronic fence or crosses the electronic fence.
In one embodiment, the self information further includes current behavior information; after self information of a user is acquired, the near-electricity early warning method further comprises the following steps: alarming when the self information is judged to accord with the preset behavior early warning condition; for example, the current behavior information is obtained by acquiring current sensor information and combining the sensor information; for example, when the current behavior information in the self information is judged to accord with the preset behavior early warning condition, an alarm is given. Therefore, when the user has abnormal behaviors, whether the current behaviors meet the behavior requirements or not can be automatically judged, and when the current behaviors do not meet the behavior requirements, namely the current behavior information in the self information meets the preset dressing early warning conditions, an alarm is given. As an example, the predetermined behavior warning condition may include too fast or too slow speed, abnormal position of the limb, and/or deviation from a predetermined path range, for example, the user may suddenly run fast, the user may suddenly fall down, and/or the user may leave a certain area during working hours. Therefore, when abnormal behaviors occur under the condition that the user voluntarily or involuntarily, the alarm can be given in time, so that the user behaviors are normalized or the user in danger is rescued in time.
In one embodiment, the environment information is acquired when the action is determined to occur, for example, when no change occurs in video monitoring, the step of acquiring the environment information does not need to be executed; for another example, when the sensor is not changed, the step of acquiring the environmental information is not required to be executed; both for the monitoring of the positioning base station and for the monitoring of the user's own equipment, respectively. Therefore, the user does not need to acquire the environmental information when the user is stationary, so that the energy can be saved, the energy consumption can be reduced, and the service life can be prolonged. In one embodiment, the near-electricity early warning method further comprises the following steps: and stopping obtaining the environmental information when the static state lasts for the preset time period. For example, when the static state is determined to continue for a preset time period, the acquisition of the environment information is stopped, and when the motion is determined to occur, the acquisition of the environment information is determined. For example, the preset time period is 5 seconds, 10 seconds, or 30 seconds, and if the still continues for 5 seconds, 10 seconds, or 30 seconds, the acquisition of the environmental information is stopped, and once the operation occurs, the acquisition of the environmental information is started. For example, the motion includes upper and lower limb motion. For another example, the action is implemented by a sensor, for example, the sensor is a vibration sensor, and when the vibration amplitude is greater than a vibration threshold, the action is determined to occur, otherwise, the user is determined to be stationary, that is, the user is in a stationary state. For example, when the static state is determined to continue for a preset time period, the acquisition of the environment information is stopped, the sleep state is entered, and when the action is determined to occur in the sleep state, the environment information is started to acquire.
In one embodiment, the near-electricity early warning method further comprises the following steps: when the wireless charging signal is sensed, charging is carried out.
