the terminal judges whether abnormal equipment numbers are retrieved in wearable monitoring equipment numbers of other wearers, and if yes, early warning information is sent out.
Because most of the existing wearable devices such as the wristband mainly adopt health management, the wearable devices are mostly used for recording sports and running, and the like, although the wearable devices comprise a positioning function, the wearable devices can perform real-time positioning, tracking and the like on personnel; but wearable equipment such as current bracelet does not contain the range finding function, can't directly record the distance between the two people who wear the bracelet. Therefore, the present embodiment provides a wearable device with a distance measurement function, and the present embodiment takes a bracelet as an example.
The bracelet includes devices such as temperature sensor, bluetooth module, memory and display, and every bracelet all distributes by only serial number, is responsible for the closely contact information of real-time supervision person's of wearing body temperature and other persons of wearing.
Detecting other wearers in a range which can be identified by the Bluetooth signal through a Bluetooth module, obtaining contact distances with other wearers in the contact range based on signal strength RSSI ranging, and recording bracelet numbers which are contacted for a long time in a close range;

in this embodiment, the RSSI ranging is performed by using a bluetooth signal, and the iBeacon mode of bluetooth can broadcast a data packet in real time, as shown in fig. 2, the data packet includes four information, i.e., UUID, Major, Minor, and Tx Power; the UUID is an equipment number, a plurality of equipment can be arranged under each equipment number, the plurality of equipment are grouped, the Major is a group number of the equipment under the equipment number, and the Minor is a specific equipment number in the group, so that the UUID, the Major and the Minor form a unique number of the bracelet and are used for identifying and determining the bracelet; tx Power is the RSSI measured at 1 meter, which can be set manually for calibration; at the iBeacon scanning end, besides the 4 pieces of information, the MAC address of the scanned equipment and the received RSSI value can be obtained, and the corresponding contact distance is calculated according to the data.
The relationship between the received signal strength RSSI and the transmission distance d is:
RSSI＝-(10×n×lgd+A)；
wherein n represents a signal propagation constant, also called propagation coefficient; d represents the distance between the test point and the sender; a represents the signal strength at 1 meter from the sender;
the distance measurement precision is related to the value of n and A, wherein A is an empirical parameter and can be obtained by measuring an RSSI value at a position 1 meter away from a sender; n describes parameters of which the signal strength decreases with the increase of the distance, the size of n depends on a specific environment, and in order to obtain an optimal n value, all reference nodes can be placed at first, the n value is changed continuously, and the optimal n value under the current environment is found.
In the embodiment, the distance measurement is carried out by using an iBeacon mode of Bluetooth; when the short-distance contact person exceeding the preset contact distance exceeds the preset contact time, the bracelet vibrates to remind the wearer, the time and the body temperature of the current wearer are stored in the EEPROM, the contact time is recorded and stored in the EEPROM in real time, and the time unit is second.
It is understood that the preset contact distance can be set by self, and in this embodiment, is set to 1 meter.
It can be understood that, the wearable detection device provided by the embodiment takes a safety bracelet as an example, and an OLED display screen can be arranged in the bracelet and used for displaying information such as body temperature data and time of a wearer and contact time of other people; EEPROM memory stores the above information; the vibration motor can be used for vibrating to remind a wearer when abnormal information exists; the mode switching key can be used for switching display data of the display screen and the like; and the MCU controller controls each unit.
The embodiment can ensure that people are not excessively dense in the epidemic situation period based on RSSI ranging, when a person who contacts in a short distance exists, the distance between the person and the contact time are recorded, the recorded distance is usually less than 1-3 meters under the general condition, and the environment between the distance is not complicated generally; even if the environment is complex enough to influence the RSSI value, a smaller RSSI value is obtained during the measurement, and the calculated distance is larger than the actual distance between the two, in the actual situation, the complex environment of such a degree plays a role in isolating the two, and the equivalent distance for isolating the two is larger than the actual distance, so the influence of the environment on the RSSI is negligible.
In this embodiment, the bracelet sends the contact information that detects to the terminal, and the terminal can be cell-phone, cell-phone APP etc. and the bracelet passes through bluetooth module and binds the cell-phone, with the date of bracelet, the person's body temperature and the contact information of wearing of year, month and day, bracelet serial number, different time quantum promptly closely contact person serial number and contact time and send to the cell-phone, realize the synchronization of cell-phone and bracelet data.
The body temperature and the contact information of the wearer are stored in the mobile phone terminal, the body temperature is judged, and if the body temperature exceeds the preset body temperature, the bracelet number is pushed to the remote management platform.
When a person enters a specific area, the mobile phone is connected with the server in the area for registration, the bracelet is bound with personal information, a plurality of terminals form a cluster, the mobile phone actively pushes related data to the remote management platform, and the abnormal bracelet number is sent to the remote management platform;
after the remote management platform receives the abnormal bracelet number or manually inputs the abnormal bracelet number, broadcasting and pushing the abnormal bracelet number to all mobile phones in the cluster, after the mobile phone end receives the abnormal bracelet number, searching whether the abnormal bracelet number exists in bracelet contact information, and if abnormal conditions exist, alarming and reminding;
when a new mobile phone terminal is accessed, the remote management platform pushes the abnormal bracelet number to the newly accessed mobile phone terminal.
The embodiment is based on RSSI range finding realization under no place limiting condition, accomplishes the distance detection between the mutual moving object, and the remote management platform carries out unified storage management to data, when special personnel need keep apart or backtrack the contact chain, can be timely and accurate confirm closely contact personnel, handle every potential hidden danger, realize the management to personnel in the specific region.
