· Product Name： T725 Electronic School Badge Tag
· Product Model：
The tag operates in an ‘active or passive mode’. The tag actively transmits a signal or is triggered by an instruction from a reader (or a low-frequency activator) to transmit a signal. The RF frequency is adjustable.
Activators distributed in various zones or inside and outside the access control have been actively transmitting low-frequency signals at a low frequency of 125 KHz. Any dual-frequency tags that pass through the activator signal range can be activated successfully. And the digital number transmitted by the activator is obtained. The RSSI field strength value is calculated. The tag then transmits data such as "tag ID + tag status + activator number + RSSI value" at 2.4 GHz frequency.
The adjacent 2.4GHz reader will upload the received data to the host computer with various standard interfaces such as RJ45 and RS485.
A low-frequency 125KHz activator can be placed respectively inside and outside the access control. The effective activation range could be adjusted by changing the antenna position, adjusting the transmit power, and choosing different antenna shapes and dimensions. The dual-frequency tags will be activated by the activators inside and outside in turn when the tags pass through the access control. According to the activating order, the entry and exit judgment could be accurately made. Also the accurate floor location could be determined.
According to the characteristics of 125 KHz low frequency such as field strength RSSI value, strong penetrating power, clear boundary, easy adjustment of signal range, etc., several activators can be used for real-time locating of RTLS zones more accurately.
When the active tag and the matched the reader communicates, special communication protocol is used to verify the legitimacy of the device. In order to prevent data cracking, the meticulous encryption algorithm is developed to ensure data security in the communication process.
The product fully considers the application requirements of industrial environment such as waterproof, dust-proof and shock protection.
It conforms to ISO18000-4 standard and specification.
