Abstract

A wireless warning system (100) includes a primary terminal (10) and a secondary terminal (20). The primary terminal includes a first alarm apparatus (11) and a first communicating apparatus (12). The secondary terminal includes a second alarm apparatus (21) and a second communicating apparatus (22). The first communicating apparatus and the second communicating apparatus contact with each other and respectively calculate a distance between the primary terminal and the secondary terminal. The first alarm apparatus and the second alarm apparatus alarm when the calculated distance being beyond a predetermined safe distance.

Claims

1. A wireless warning system, comprising:

a primary terminal which comprise a first alarm apparatus and a first communicating apparatus connected to the first alarm apparatus; and

a secondary terminal which comprise a second alarm apparatus and a second communicating apparatus connected to the second alarm apparatus;

the first communicating apparatus and the second communicating apparatus communicating with each other thereby cooperatively calculating a distance between the primary terminal and the secondary terminal, the first alarm apparatus and the second alarm apparatus alarming when the calculated distance is beyond a predetermined safe distance.

2. The wireless warning system as claimed in claim 1, wherein the first communicating apparatus includes an operating module used to set the predetermined safe distance.

3. The wireless warning system as claimed in claim 1, wherein the first communicating apparatus includes a first transceiver module, a first searching module and a first matching module;

the first transceiver module sends wireless signals to the secondary terminal and receives wireless signals from the secondary terminal, the first searching module searches the secondary terminal in a wireless network, the first matching module matches the primary terminal with the secondary terminal for establishing an interactive wireless communication.

4. The wireless warning system as claimed in claim 3, wherein the first communicating apparatus includes a first controlling module electronically connected to the first transceiver module.

5. The wireless warning system as claimed in claim 4, wherein the first controlling module periodically receives an instantaneous RSSI numerical value of the wireless signals sent by the secondary terminal from the first transceiver module, thus calculates a distance between the primary terminal and the secondary terminal according to the RSSI numerical value of the wireless signals.

6. The wireless warning system as claimed in claim 3, wherein the first alarm apparatus includes a first reproducer and a vibrating member.

7. The wireless warning system as claimed in claim 1, wherein the second communicating apparatus includes a second transceiver module, a second searching module and a second matching module;

the second transceiver module sends wireless signals to the primary terminal and receives wireless signals sent from the primary terminal, the second searching module searches the primary terminal in a wireless network, the second matching module matches the secondary terminal with the primary terminal for establishing an interactive wireless communication.

8. The wireless warning system as claimed in claim 7, wherein the second alarm apparatus includes a second reproducer and an alarm apparatus, which is a lamp.

9. The wireless warning system as claimed in claim 8, wherein the second controlling module periodically receives an instantaneous RSSI numerical value of the wireless signals sent by the primary terminal from the second transceiver module, thus calculates a distance between the primary terminal and the secondary terminal according to the RSSI numerical value of the wireless signals.

10. The wireless warning system as claimed in claim 7, wherein the second alarm apparatus includes a second reproducer, which is electronically connected to the second communicating apparatus.

14. The wireless warning method as claimed in claim 1, wherein the step of activating the first communicating apparatus and the second communicating apparatus to communicate with each other thereby calculating a distance between the first user and the second user includes a substep of respectively receiving an instantaneous RSSI numerical value of the wireless signals sent by each other, thus respectively calculating the distance between the primary terminal and the secondary terminal according to the RSSI numerical value of the wireless signals.

15. The wireless warning method as claimed in claim 14, wherein the period of the primary terminal and the secondary terminal receiving an instantaneous RSSI numerical value of the wireless signals sent by each other is approximately 4-6 seconds.

11. A wireless warning method, comprising the steps of:

providing a primary terminal carried by a first user and a secondary terminal carried by a second user, the primary terminal comprising a first alarm apparatus and a first communicating apparatus, the secondary terminal comprising a second alarm apparatus and a second communicating apparatus;

setting a predetermined distance recorded in the primary terminal and recording the predetermined distance in the secondary terminal;

activating the first communicating apparatus and the second communicating apparatus to communicate with each other thereby calculating a distance between the first user and the second user; and

activating the first alarm apparatus and the second alarm apparatus to alarm when the distance calculated between the first user and the second user is beyond the predetermined distance.

12. The wireless warning method as claimed in claim 11, further comprising a step of interactive detecting between the primary terminal and the secondary terminal after the step of providing a primary terminal carried by a first user and a secondary terminal carried by a second user.

13. The wireless warning method as claimed in claim 12, further comprising a step of matching the primary terminal and the secondary terminal for establishing a special wireless contact after the step of interactive detecting between the primary terminal and the secondary terminal.

16. The wireless warning method as claimed in claim 11, wherein the first alarm apparatus and the second alarm apparatus are activated to alarm when the distance between the primary terminal and the secondary terminal is calculated to be beyond the predetermined distance.
