Wireless communication packet-oriented security device

This creation relates to a security device, and more particularly to a security device with a wireless communication packet guide.

The wireless communication system can include a number of repeaters to assist in communication between the source and destination. The signal sent by the source carries information to be transmitted to the destination, and is transmitted in a wireless network environment in the form of a packet. Therefore, when the signal sent by the source is not strong enough, the packet cannot be sent to the destination, so the repeater receives the packet during transmission, and then sends the packet to the wireless network environment with a certain signal strength. The packet can be delivered to the destination.

Basically, the repeater can be unidirectional or bidirectional. That is, the repeater can amplify the signal only in a single direction (eg, from the transmitting end to the receiving end) or bi-directionally amplify the signal (eg, from the transmitting end to the receiving end or the receiving end to the transmitting end). A packet is a material that is passed over a wireless network.

In general, the source (such as a security host or wireless sensor) or the sender (such as a security host, wireless repeater, or wireless sensor) sends a certain signal strength, so that the communication distance is limited, and modern Most of the buildings are constructed of reinforced concrete to reduce the effective distance of wireless communication. Therefore, in order to establish a complete wireless network environment within the signal strength allowed by regulations, many wireless repeaters must be installed within the protection range of the security device.

However, in a wireless network environment, multiple wireless repeaters transmit packets to each other, which easily lead to packet divergence, which affects communication quality and communication time.

Therefore, how to efficiently transmit a packet via a wireless repeater in a wireless network environment is a subject that the creators of the present invention and those skilled in the related art are eager to improve.

In view of this, the present invention proposes a security device with a wireless communication packet guide, including a security host, a wireless repeater, and a wireless sensor. The security host has a security level number, and the security host generates a packet and fills in the security level number in the packet. The wireless repeater has a relay level number, the wireless repeater receives the packet and checks the security level number of the packet, and the wireless repeater fills in the relay level number in the packet and transmits the packet. The wireless sensor has a perception level number and the wireless sensor receives the packet to process the packet. The packet has a perceptual level number, a security level number, or a relay level number.

In one embodiment, a security device with a wireless communication packet guide includes a security host, a plurality of wireless repeaters, and a wireless sensor. The security host generates a packet. Each wireless repeater has a relay level number, and each wireless repeater fills in a relay level number in the packet when transmitting the packet, wherein the wireless repeaters determine whether to transmit the packet according to the relay level number of the packet . The wireless sensor receives the packet and acknowledges the relay level number of the packet to process the packet.

This creation can be used for the perceived level number, security level number or relay of the packet. The level number, so that a plurality of wireless repeaters can determine whether to send a packet, thereby converging the amount of packets in the wireless network environment. Moreover, the relay pre-receipt level of the wireless repeater can be set, so that the wireless repeater checks whether the packet's sensing level number, security level number, or relay level number meets the pre-received level before processing the packet and sending the packet. Packets, while converging the amount of packets in the wireless network environment and reducing the time spent processing packets, thereby maintaining good communication quality and improving effective communication time.

FIG. 3 is a schematic diagram of a third embodiment of a wireless communication packet-oriented security device. The embodiment of the third embodiment can be substantially the same as the second embodiment, wherein the security device 1 with wireless communication packet guidance further has a wireless repeater 203, a wireless sensor 304 and a wireless sensor 305.

Referring to FIG. 3 and FIG. 4, the wireless repeater 201 and the wireless repeater 203 are both located in a communication effective range that can receive the packet D transmitted by the security host 10, and the pre-receive level 203a of the wireless repeater 203 can be set. To secure the level number 11 or the awareness level number 314. The relay pre-receive level 202a of the wireless repeater 202 can be set to the relay level. The unique number 211, the perceived level number 313, or the perceived level number 314. The wireless sensor 304 receives the packet D and checks the packet D that carries the relay level number 213 and confirms that it is the desired processing. The wireless sensor 305 receives the packet D and checks the packet D that carries the relay level number 212 and confirms it to be the desired processing.

In the wireless communication packet-oriented security device 1, if the security host 10 wants to transmit the packet D to all the wireless sensors (the example is the wireless sensor 303, the wireless sensor 304, and the wireless sensor 305), the security can be saved. The level number 11 is filled in the address field D0, and the packet D is received by the wireless repeater 201, and the relay level number 211 is filled in the address field D0 to enable the wireless repeater 202 to receive the packet D, and then After receiving the packet D, the wireless repeater 202 fills in the relay level number 212 in the address field D0, and causes the wireless sensor 303 and the wireless sensor 305 to receive the packet D and check that the relay level number 212 is carried. The packet D to be processed, and the packet D received by the wireless repeater 203 is filled in the relay level number 213 in the address field D0 to enable the wireless sensor 304 to receive the packet D and check that the relay level number 213 is carried. It is confirmed as the packet D to be processed.

Alternatively, the security level number 11 can be entered in the source end field D1, and all the wireless perceptrons (in this example, the wireless sensor 303, the wireless sensor 304, and the wireless sensor 305) are indicated in the destination field D2. The packet D is sent from the source end to the destination end through the wireless repeater. The manner in which the wireless repeater operates to send the packet D has been described in the second embodiment and will not be described herein.

Furthermore, if the security host 10 only transmits the packet D to the specific wireless sensor, such as only to the wireless sensor 303 and the wireless sensor 304, the destination port of the packet D can be used. When the bit D2 is filled with the sensing level number 313 and the sensing level number 314, the wireless repeater 201 and the wireless repeater 203 automatically check whether the destination end field D2 is the relay prefetch level after receiving the packet D. At this time, the wireless repeater 203 determines that the sensing level number 314 of the destination end field D2 is the relay pre-receive level, fills in the relay level number 213 and transmits the packet D to the wireless network environment, and the wireless repeater 201 It is also determined that the sensing level number 313 of the destination end field D2 is the relay pre-receiving level, and the packet D is sent to the wireless network environment. That is to say, the relay pre-receive level of each wireless repeater may be provided with the sensing level number of the transmission packet D path, and it is determined whether to send the packet D.

In some implementations, the wireless repeater is subject to a possibility of failure. Therefore, the packet D may have a count value C, and if the packet D is transferred to one of the wireless repeaters to another wireless repeater of the same relay level number, the count value C of the packet D is changed.

For example, when the wireless repeater 201 fails, the wireless sensor 303 and the wireless sensor 305 cannot receive the packet D and reply the acknowledgement signal, resulting in a timeout reply, so that the security host 10 resends the same packet D. At this time, since the wireless repeater 201 and the wireless repeater 203 are both located within the communication valid range in which the packet D transmitted by the security host 10 can be received, the relay level number 213 can be set to be equal to the relay level number 211. The packet D is transferred to the wireless repeater 203, and the count value C of the packet D is changed, and is incremented by 1 from the originally set count value C equal to 0. Moreover, when the count value C of the packet D is greater than 0, the wireless repeater 203 can replace the wireless repeater 201 and maintain the operation of the security device 1 with wireless communication packet guidance.

Wherein, the same packet D can be indicated by the packet sorting number. Based on the sequence number of the packet, the wireless repeater determines whether the packet of the same sequence number has been received in the timeout reply time according to the sequence number of the packet, and does not repeatedly transmit the packet.

The packet D of the wireless repeater transmitting the source end from the destination end may be a packet forwarded according to the receiving end packet, or the packet D may be added only to the level number or covered in the corresponding field, and no packet is sent in the corresponding packet. The packet transmitted to the destination data.

In some implementations, the security host, the wireless repeater, and the wireless sensor can support one or more of various wireless communication technologies, protocols, or standards such as CDMA, TDMA, OFDM, OFDMA, WiMAX, or Wi-Fi. .

The creation can utilize the sensing level number, the security level number or the relay level number of the packet, so that a plurality of wireless repeaters can determine whether to send the packet, thereby converging the amount of packets in the wireless network environment. Moreover, the relay pre-receipt level of the wireless repeater can be set, so that the wireless repeater checks whether the packet's sensing level number, security level number, or relay level number meets the pre-received level before processing the packet and sending the packet. Packets, while converging the amount of packets in the wireless network environment and reducing the time spent processing packets, thereby maintaining good communication quality and improving effective communication time.
