Product Overview

WE-T72 long-distance range electron label is specially uses to the personnel or the article to carry on the localization electron label. The electronic label regularly broadcasts the label ID information to the outside wireless, sends the distance openly up to 300 meters. The label reads the card not only can receive to the nearby label's ID information, but also can calculate according to the wireless signal's field strength the label from the reads the card the distance. By comprehensively analyzing the data received from multiple readers, the specific location of the tag can be derived.
Can use the supporting bolt to fix the label on the safety helmet, also can use the screw or 3M adhesive to fix the label on the articles (vehicles), in order to realize the effective management of the workers, articles and vehicles. When the electronic label is applied in the intelligent construction site project, only a small number of base stations need to be deployed to realize the positioning of the workers in the whole construction site, and the label's one-key call for help can enable the workers to be rescued in time.
The tag uses an ER14505 battery with a power of 2700mAh and no less than 70 million wireless transmissions (default transmission frequency 1Hz). There is an undervoltage reminder when the battery power is not enough, you can replace the battery yourself. Wide operating temperature range (-40 ℃ ~ 85 ℃), IP67 protection grade, can work in a variety of harsh conditions.
The electronic label has the movement detection function, the long time is stationary (default 10 minutes) automatically stops working, the maximum degree saves the electric energy.

Application Industries

Management of people, goods and vehicles on site and at construction sites

Positioning principle

ZIGBEE localization technology and application of WorldTech

Label Ranging Formula

BTS accepts tag field strength as a function of distance

Measurement of the wireless signal field strength of the tag to calculate the distance between the tag and the antenna, distance and wireless signal strength for the exponential curve relationship between

There are 3 values that we need to measure and calibrate over and over again

1, L0: the signal strength when the distance between the tag and the reader is 0 cm, the measured value is -8dBm.
2、 L1: The signal strength when the distance between the tag and the reader is 40 centimeters, the measured value is -20dBm.
3, L2: label and reader distance of 100 cm when the signal strength, measured value of -30dBm

Based on these three values, the derived equation is as follows.

Due to chart size limitations, only correspondences within a distance of 6 meters are shown

Label Positioning Principle

Approximate location for installing base station measurement tags

In the warehouse, the workshop's surroundings installs the good localization base station (reads the card) to be able to measure the label's approximate position. In the effective range of each base station will get the electronic label and their own distance, according to the 2 ~ 3 closest to the electronic label of the base station's test value, may get the electronic label in the space of the approximate position. Positioning accuracy 1~3 meters

Motion Detection Improves Label Life

Selects "the movement detects" the working mode electronic label, the label long time does not have the movement (the default 10 minutes), the label automatically stops working. This can effectively save power, greatly prolongs the label to use the time. When the label is used as the personnel, the vehicle localization, the recommendation chooses "the movement detects" the working mode electronic label. Tag from the motion state to the stationary state of the detection time default for ten minutes (can be customized to 1 ~ 60 minutes). Stationary state tag default does not work (can be customized to work slowly, 1 ~ 60 seconds to send a). Need to customize and our customer service contact after the order!

Find labels directly with handhelds

Without a locator system installed, it is still possible to find a tag using only the handheld. Directly in the handheld enter the label ID, or use inventory software to send the label ID of the item to the handheld, the handheld to start looking for, you can confirm that the label is in the vicinity of the label to confirm the initial location of the label, so that the handheld to send commands to activate the label, through the sound and light reminder can be easily find the label. Methods are as follows:
Turn on the handheld, enter the "Find" page, enter the corresponding label code, click the "Start" button, you can find whether the label is nearby. If you find the label in the vicinity, the handheld will display the actual distance between the label and the handheld, you can judge the distance value of the label near and far, to quickly determine the label in which area, to improve the efficiency of the search for items.

The found tag glows (blinks continuously) to remind the user of the tag's location. If you still can't find it, you can click the horn button at the bottom right, the tag will beep, beep, beep, beep, beep, beep, beep to make you find the tag more conveniently.

Industry Application Notes

Production management system call tags

The label positioning function is implanted into the production management system, the management system can not only know the location of the label, if necessary, you can directly call the label, so that the label luminous, sound, through the sound and light reminder to easily determine the location of the items, the production process is more accurate and efficient.
The production management system sends the call command to the tag positioning system, the tag positioning system according to the current location of the tag, the closest base station (reader) to the tag to send call commands, the called tag sends sound and light reminders.

Hospital equipment asset management

Hospital asset management includes: ① general office equipment, refers to commonly used office and business equipment; ② special equipment, refers to all the equipment belonging to the hospital specifically for a particular job; ③ medicines and displays and other management. These items are many and varied, manual management is time-consuming and laborious, and each inventory is prone to errors!

The use of ZIGBEE locator tags and readers from WorldTech, combined with the software process can be paired with a complete system.

attribute byte (computing)

The data sent wirelessly by the tag mainly includes tag ID, tag type, undervoltage reminder, extended data, etc. Different types of tags have the same format except for "extended data". Different types of tags, in addition to the "extended data", the format of the other data are the same.

Extended Data Length: 1, Fixed 1-byte extension byte indicating current power level and status of the call button.
Campaign Logo:: 1 (motion), 0 (stationary, one minute of inactivity to stationary)
Label Type:: 0 (general labeling)
undervoltage sign: 1 (undervoltage), 0 (normal)
Extended Data Bytes::

 

BIT0: SOS alarm
1: Alarm
0: Normal
Pressing the SOS alarm for more than 0.5 seconds will trigger the SOS distress alarm, and the tag will report the data with the SOS logo in the following 10 seconds. During the alarm process, the buzzer inside the tag continuously emits a "beep beep beep" sound to remind the caller that the SOS alarm message is being sent.

BIT 4~7: Remaining power

battery indicator: 0~A, indicating the power of 0%~100% respectively. For example, a power indication of 6 means that the tag still has 60% of power left.

Note: Refer to the reader's instruction manual for the format of the complete tag packet read by the reader.

 

Motion Detection Mode

When the tag has no movement for a long time (default 10 minutes), the tag automatically stops working. This can effectively save power and significantly extend the time of use of the label, especially suitable for the label in the personnel, vehicle positioning applications.
The detection time for the label to switch from motion to stationary state, in other words, the time to switch to stationary state when no motion event is detected for a long time in the motion state, the factory default is ten minutes. If you need to modify the length of detection time, you can contact our customer service.
After entering the stationary state, the tag stops working by default (no ID information is emitted), if the user needs the tag to still keep working slowly in the stationary state, he can contact our customer service, and the working frequency can be selected as 1 time in 1 second~1 time in 60 seconds.
