It should be noted that, for simplicity of description, the method embodiments are shown as a series of acts, but it should be understood by those skilled in the art that the embodiments are not limited by the order of acts, as some steps may occur in other orders or concurrently in accordance with the embodiments. Further, those skilled in the art will appreciate that the embodiments described in the specification are presently preferred embodiments, and that the acts are not necessarily required by the embodiments of the invention.
The embodiment discloses a wireless fire alarm system with terminal awakening function, including: the gateway and front-end equipment comprising a communication board, and an alarm host connected with the gateway;
the communication board is used for monitoring the network state according to a preset rule; when a wake-up packet is monitored, waking up the communication board; sending a wake-up response signal; sending alarm information; after the communication is completed, returning to the monitoring network state according to a preset rule; the gateway is used for sending a wake-up packet; receiving the communication board response data; the communication board is communicated with the communication board and receives alarm information; forwarding the alarm information to the alarm host.
In this embodiment, referring to fig. 3, the gateway is designed to wake up the front-end device including the communication board by using consecutive short packets, and the time t3 of a single short packet is 1.4 seconds, and 5 packets are sent consecutively. The switching interval t4 between packets is about 40 ms. The purpose of this design is that after the gateway finishes sending the two previous short packets, the communication board just wakes up to perform CAD detection (the CAD detection time t1 is not greater than the switching interval t4 between the wake-up packets), then just is the switching interval t4 of the gateway, the communication board does not detect the preamble, the CAD detection time t1 coincides with the switching interval t4, at this time, the communication board cannot be woken up, just misses the time t3 of the wake-up packet from the CAD detection time t1 at the C mark as shown in fig. 3, the communication board continues to enter a sleep time t2, and after switching to the next sleep period interval t2 (the sleep period time t2 is 4 seconds), the short packet of the gateway must be in a data transmission state, so that the front-end device can only reliably receive data, that is, the subsequent CAD detection time t1 needs to correspond to the time t3 of the wake-up packet, and communication can be woken up only partly coincident.
The gateway also sends 3 packets after the communication board misses, where the time relationship must satisfy the relation of Timer2< Timer1< Timer3, where Timer 1=t2 is a sleep period, timer2 is the time from the remaining continuous short packet to the last switching interval, i.e. Timer 2=2×t3+2×t4, and Timer3 is the total time of the remaining continuous short packet after the switching interval t4 is missed, i.e. Timer 3=3×t3+2×t4. Here:
Timer1＝4000ms，
Timer2＝1400×2+2×40＝2880ms，
Timer3＝1400×3+2×40＝4280ms，
the communication board ensures that the communication board can certainly monitor the gateway wakeup packet data after missing the data packet for the first time (no matter at any position of the switching interval) and after the next sleep wakeup. The longer the single short packet, the fewer packets are sent and the shorter the total time. The present solution preferably takes 1.4 seconds as a short packet time, and the total time is 1.4x5+4x0.04=7.16 s, i.e., the wake-up time of the communication board does not exceed 7.16s.
In another embodiment, referring to fig. 4, with a time t3 'of 0.9 seconds as a short packet, the maximum missed switching interval t 4' of the communication board is between the 4 th packet and the 5 th packet sent by the gateway, if the communication board just wakes up to perform CAD detection, (the CAD detection time t1 'is not greater than the switching interval t 4' between wake-up packets), it is just the switching interval t4 'of the gateway, the communication board does not detect the preamble, the CAD detection time t 1' coincides with the switching interval t4 ', the communication board cannot be woken up, the communication board just misses the time t 3' of the packet from the CAD detection time t1 'at the C mark as shown in fig. 4, the communication board continues to enter a sleep time t 2', and after the next sleep period interval t2 '(the sleep period time t 2' is 4 seconds), the short packet of the gateway must be in a data transmission state, so that the front-end device can reliably receive data, that is, and the subsequent CAD detection time t1 'needs to coincide with the wake-up time t 3', at least partially, and the communication board can not wake up from the time t3 'of the CAD detection time at least coincides with the time t 3' of the wake up packet.
As shown in fig. 4, the relationship of time must satisfy the relationship of Timer2 ' < Timer1 ' < Timer3 ', where Timer1 ' =t2 ' is the sleep period, timer2 ' is the time from the remaining continuous short packet to the last switching interval, i.e., timer2 ' =4×t3 ' +4×t4 ', and Timer3 ' is the total time from the remaining continuous short packet after the switching interval t4, i.e., timer3 ' =5×t3 ' +2×t4 '.
The next time the sleep wakes up for CAD detection, the state in which the gateway sends the data must be just at the time the communication board wakes up. Here:
Timer1＇＝4000ms,
Timer2＇＝900×4+4×40＝3760ms,
Timer3＇＝900×5+4×40＝4660ms,
the total time of the whole continuous short packet is 900× 9+8 ×40=8420ms, so the time design of the short packet is not suitable to be too long or too short, the too long time-out time of the front-end device is caused to be too long (the time-out time of the front-end device is required to be longer than the time of the short packet), the too large power consumption of the received data after being awakened by mistake is caused, the too short time is caused to be too long, the gateway issues a command, the response speed of the device is too slow, and the timeliness is affected. That is, the communication board must wake up to receive data the next time after missing a data packet the first time.
