Fig. 1 is a schematic structural view of a livestock delivery prompting system according to an embodiment of the present invention. Fig. 4 is a flow chart of a method for prompting delivery of livestock according to an embodiment of the invention. As shown in the figure, the specific embodiment of the invention comprises a livestock delivery prompting method, which comprises the following steps:
A. after detecting the livestock delivery process by using the livestock delivery detection device, sending a trigger signal through a first broadcast channel;
B. after the signal relay device detects the trigger signal, connection is established with the livestock delivery detection device through a second communication channel, and detection information and control information are interacted;
C. the signal relay device communicates with the remote server through a third communication channel, and sends the received detection information and the information of the signal relay device to the remote server.
The specific implementation mode of the invention is characterized in that a triple nested network is used, and the first broadcast channel has the characteristics of wide transmission range, low power consumption, strong signal anti-interference performance, low speed and no need of handshaking, is suitable for the livestock delivery detection device to send a trigger signal to the surrounding, announces the existence of the device and has information to be processed. The second communication channel has the advantages of low power consumption, ad hoc network, simple protocol and the like, and is suitable for information interaction between the livestock delivery detection device and the signal relay device.
The livestock delivery detection device is, for example, a device provided in a livestock delivery passage, senses a livestock delivery process due to a sudden change in external pressure when discharged from the delivery passage, and needs to report a livestock delivery event to a surrounding signal relay device in the form of a trigger signal. In addition to pressure detection, characteristic information such as body temperature and heart rate of livestock can be detected, and in addition to detection, warning information such as light or alarm sound can be sent to the outside. The livestock delivery detection device is not provided with an external power supply and is driven by a battery arranged in the livestock delivery detection device, so that low power consumption is a basic requirement; as also shown in fig. 1, the specific delivery location and time of livestock is both occasional and random. Based on the above factors, the livestock delivery detection device adopts the first broadcast channel with wide transmission range, low power consumption, strong signal anti-interference performance, low speed and no need of pre-handshake to broadcast the trigger signal, and performs information interaction with the signal relay device through the second communication channel with low power consumption, ad hoc network, simple protocol and stable signal.
For the signal relay device, the signal relay device can be a ground device which is fixedly arranged, and is convenient for wiring and obtaining power, so that a third communication channel is utilized to communicate with each other or a remote server besides the two communication channels, and the third communication channel has the characteristics of large channel capacity, high speed, mature network architecture and the like.
Therefore, through the triple nested communication channels, the method and the system well solve the requirements of sporadic performance, randomness and power consumption persistence in the livestock delivery prompting process, and are suitable for a special application scene of large-scale livestock cultivation.
The information of the signal relay device comprises an identification symbol, specific position, current report time information and the like of the signal relay device, so that the remote server can comprehensively know the delivery specific information of the livestock.
Fig. 2 is a schematic view showing a part of a livestock delivery prompting system according to an embodiment of the present invention. As shown in the figure, in the livestock delivery prompting method of the specific embodiment of the invention, the first broadcast channel is a Bluetooth low-power consumption channel, the livestock delivery detection device is a Bluetooth low-power consumption slave device, and the signal relay device is a Bluetooth low-power consumption master device; when the livestock delivery detection device detects the livestock delivery process, a trigger signal is sent on a Bluetooth low-power consumption channel in a time interval mode, wherein the trigger signal comprises an identification symbol of the livestock delivery detection device; the signal relay device periodically monitors the Bluetooth low-power consumption channel according to a preset time interval and receives a trigger signal.
The Bluetooth low energy channel BLE is different from the traditional Bluetooth, 79 channels of the traditional Bluetooth are divided into 40 channels, and the bandwidth is changed from 1MHz to 2MHz. 37, 38, 39 as the primary broadcast channel, and when a BLE device is in broadcast mode, it periodically transmits broadcast messages on each broadcast channel. The time interval between every two sets of broadcast messages consists of a fixed interval and a random delay. This is mainly used to reduce the probability of signal collision between devices and improve the reliability of BLE connections.
The BLE broadcast message is composed of four parts, namely a preamble, an access address, a protocol data unit and a CRC check code, and in the specific embodiment of the present invention, the livestock delivery detection device may carry its own identification in the protocol data unit to conform to the ID, so as to enable the surrounding signal relay devices to find themselves. The current BLE broadcasting capacity can be increased to 256 bytes, and the effective transmission distance can exceed 300 meters, so that the requirements of the first broadcasting channel with wide transmission range, low power consumption, strong signal anti-interference performance, low speed and no handshake are satisfied.
In addition, in the livestock delivery prompting method according to the specific embodiment of the invention shown in fig. 2, the signal relay device distributes a plurality of sectors according to a preset angle, and different sectors are distinguished according to different signal frequency points of the bluetooth low energy channel; the livestock delivery detection devices corresponding to different sectors send trigger signals according to the signal frequency of the sector; and the signal relay device monitors sequentially according to different frequency points in a preset time interval and receives the trigger signal omnidirectionally.
In order to reduce the interference of the coverage area of each signal relay device and realize a simple networking relation as much as possible, in the specific embodiment of the invention, a first broadcast channel is established by utilizing a sector mode, in this case, the signal relay device distributes three sectors according to 120 degrees, and different sectors are distinguished according to different signal frequency points of a Bluetooth low-power consumption channel, for example, 37, 38 and 39 broadcast channels are respectively adopted; while the adjacent signal relay devices are also distributed in three sectors at 120 degrees, but are offset from each other in position. An area is covered by the broadcast channel No. 37 for the adjacent first signal relay device and the broadcast channel No. 38 or 39 for the adjacent second signal relay device, which has the advantage that when the livestock delivery detection device corresponding to the first signal relay device transmits the trigger signal in this area, the trigger signal is preferentially detected by the first signal relay device, the network complexity is reduced, and the possibility of forwarding the trigger signal between the signal relay devices is reduced.
As described above, the first broadcast channel is a BLE communication channel, which has an advantage in that a transmission distance is long, and no prior handshake is required. Therefore, blind spots are not caused, but a problem is that a trigger signal transmitted by one livestock delivery detection device may be received by a plurality of signal relay devices, so as to reduce network complexity and improve reliability, in the embodiment of the invention, a corresponding relationship is established between the livestock delivery detection device and the signal relay devices, for example, the first signal relay device corresponds to the livestock delivery detection device with identification symbols of 0001-0008; when the first signal relay device detects the trigger signal sent by the livestock delivery detection device with the identification symbol of 0009, the trigger signal is not in information interaction or control information sending with the livestock delivery detection device through the second communication channel, but is broadcasted and forwarded to other signal relay devices through the third communication channel, as shown in fig. 3 and 5. After receiving the forwarded trigger signal, the other signal relay devices find the corresponding relation between the signal relay devices and the livestock delivery detection device, find that the livestock delivery detection device belongs to the corresponding livestock delivery detection device, for example, the second signal relay device has the corresponding relation with the 0009 livestock delivery detection device, and directly interact information and send control information with the 0009 livestock delivery detection device through a second communication channel.
In order to reduce the number of such broadcast forwarding occurrences, the present embodiment employs a sector configuration of the first broadcast channel, with one region belonging to the coverage of the broadcast channel No. 37 for the adjacent first signal relay device and belonging to the coverage of the broadcast channel No. 38 or 39 for the adjacent second signal relay device. As previously described, this has the advantage that when the livestock delivery detection means corresponding to the first signal relay means transmits a trigger signal in this region, it is preferentially detected by the first signal relay means, reducing the complexity of the network and reducing the likelihood of the trigger signals being forwarded to each other between the respective signal relay means.
In addition, in the livestock delivery prompting method, after the livestock delivery detection device detects the delivery process of the livestock, trigger signals are sent at intervals according to a mode of adding random delay to declaration intervals; in the process of sending the trigger signal by the livestock delivery detection device, gradually reducing the declaration interval and the range of random delay according to the time interval between the current sending of the trigger signal and the first sending of the trigger signal; or the range of announcement intervals and random delays is reduced according to the condition that the livestock delivery detection device detects the livestock delivery process.
When a BLE device is in broadcast mode, it periodically transmits broadcast messages on the broadcast channel. The time interval between every two groups of broadcast messages is composed of a fixed interval and a random delay, wherein the fixed interval is in a value range of 20 milliseconds to 10.24 seconds, the step length is 0.625 milliseconds, and the random delay is a pseudo-random value in a value range of 0 to 10 milliseconds, and the pseudo-random value is automatically generated by the system and added into the broadcast interval. This is mainly used to reduce the probability of signal collision between devices and improve the reliability of BLE connections.
Since the livestock delivery detection device has low power consumption and complex surrounding conditions, there is a possibility that the transmission signal is not detected by the signal relay device corresponding to the device at the first time, and thus the trigger signal needs to be broadcast for a plurality of times. In a specific embodiment of the present invention, the livestock delivery detection device is specifically configured to gradually reduce the announcement interval and the range of random delay according to the time interval between the current transmission trigger signal and the first transmission trigger signal; or the range of announcement intervals and random delays is reduced according to the condition that the livestock delivery detection device detects the livestock delivery process.
For example, the first time of sending the trigger signal by the livestock delivery detection device is t0, and then the second time of trigger signal is sent in a mode of randomly delaying according to a 10-second announcement interval+ (0-10 milliseconds); the third trigger signal … … is then sent in a random delay of 9.5 seconds + (0-9.5 milliseconds), which has the advantage of alerting the signal relay device more and more urgently, and as the delivery process continues, the situation becomes more and more urgent, requiring the trigger signal to be scanned by the signal relay device more quickly.
In another case, the announcement interval and the range of random delay are also reduced when the livestock delivery detection device detects information such as abnormal temperature of the livestock body, abnormal heart rate, etc. The probability and priority of the trigger signal being sensed is increased. Therefore, the invention can improve the safety of livestock delivery and reduce the accident rate of the livestock delivery process.
In addition, fig. 5 is a schematic flow chart of a method for prompting delivery of livestock according to an embodiment of the invention. As shown in the figure, in the livestock delivery prompting method according to the embodiment of the invention, the signal relay devices comprise a plurality of signal relay devices which are communicated with each other according to a third communication channel; a corresponding relation is preset between each signal relay device and a plurality of livestock delivery detection devices arranged around the signal relay device; when a signal relay device receives a trigger signal of a livestock delivery detection device, and the livestock delivery detection device is identified to not belong to the livestock delivery detection device meeting the preset corresponding relation through an identification symbol of the livestock delivery detection device in the trigger signal, the signal relay device broadcasts and forwards the trigger signal of the livestock delivery detection device in a plurality of signal relay devices through a third communication channel; after receiving the triggering signal of the livestock delivery detection device forwarded by the broadcast, the signal relay device meeting the preset corresponding relation with the livestock delivery detection device is connected with the livestock delivery detection device through a second communication channel, and the detection information and the control information are interacted.
In order to reduce the complexity of the second communication channel network, improve the reliability of communication in the embodiment of the invention, ensure the safety of the communication channel and improve the safety of livestock delivery, in the embodiment of the invention, a corresponding relationship is established between the livestock delivery detection device and the signal relay device, for example, the first signal relay device corresponds to the livestock delivery detection device with the identification symbol of 0001-0008; the second signal relay device corresponds to the livestock delivery detection device … … with the identification number of 0009-0016. Each signal relay device only interacts detection information and sending control information with the livestock delivery detection device meeting the corresponding relation through the second communication channel, and the arrangement has certain difference with the basic networking mode of ZigBee, so that the safety, reliability and instantaneity of information transmission can be better ensured. In practice, the livestock delivery detection device adopts the first broadcast channel to send the trigger information, and the trigger information is easily detected by the signal relay device without correspondence, and although the possibility is reduced by setting the first broadcast channel in a sector manner, the possibility still cannot be completely eradicated. In this case, the present invention adopts a method of broadcasting and transmitting the trigger signal to the plurality of signal relay apparatuses, thereby ensuring that the signal relay apparatus corresponding to the livestock delivery detection apparatus can receive the trigger signal. And then the detection information and the transmission control information are interacted through the second communication channel.
In addition, in the livestock delivery prompting method of the specific embodiment of the invention, the second communication channel is a ZigBee communication channel, the signal relay device is used as a ZigBee network coordinator, and a beacon is continuously transmitted by using a preset ZigBee channel; after the livestock delivery detection device sends the trigger signal, the livestock delivery detection device is used as a node in the ZigBee network to scan and search the ZigBee network coordinator by using a preset ZigBee channel before the trigger signal is sent next time; if the beacon is detected within the scanning period, an association request is sent to the ZigBee network coordinator to establish ZigBee network connection, and then the signal relay device and the livestock delivery detection device interact with detection information and control information; the third communication channel is a local area network and a wide area network, the signal relay device is used as a site in the local area network to communicate with a network connection unit in the local area network, and the received detection information and the information of the signal relay device are transmitted to a remote server; the remote server transmits the detection information and the information of the signal relay device to an operator through a wireless access network or the Internet, for example, to a computer or an intelligent mobile terminal of the operator, and reports the delivery information of the livestock to the operator in real time.
Generally, building a complete zigbee mesh network includes two steps: network initialization, node joining the network. Wherein joining a node to a network includes two approaches: network access is provided by interfacing with the coordinator and network access is provided by the existing parent node. The Zigbee network is established by a network coordinator, and any Zigbee node has to meet the following two requirements to establish a network:
(1) The node is a full-function node and has the capability of a zigbee network coordinator;
(2) The node has not yet been connected to other networks, and when the node has been connected to other networks, the node can only act as a child node of the network, because there is one and only one network coordinator in one zigbee network. After the network coordinator finds the appropriate channel, the network coordinator will select a network identifier (PAN ID, value < = 0x3 FFF) for the network, which ID must be unique in the channel used and cannot collide with other zigbee networks. The PAN ID may be obtained by listening to the IDs of other networks and then selecting an ID that does not collide, or may be determined by manually designating a scanned channel and then determining the PAN ID that does not collide with other networks.
There are two address modes in zigbee networks: an extended address (64 bits) and a short address (16 bits), wherein the extended address is assigned by the IEEE organization for unique device identification; the short address is used for device identification in the local network, in one network the short address of each device must be unique, assigned by its parent node when the node joins the network and communicated by using the short address. For the coordinator, the short address is typically set to 0x0000.
After the above steps are completed, the zigbee mesh network is successfully initialized, and then the joining of other nodes is waited. When the node is connected to the network, a preset network coordinator is selected to join the network, and after success, a network short address is obtained and data is sent and received through the address.
After the node coordinator determines, the node first needs to establish a connection with the coordinator to join the network.
Specifically, the specific procedure of joining a node to a network may be divided into the following steps:
(1) The network coordinator is looked up.
First, the surrounding network coordinators are actively scanned and searched, if a beacon is detected within the scanning period, the relevant information of the network coordinators is obtained, and then an association request is sent to the network coordinators. After selecting the appropriate network, the upper layer will request the MAC layer to set the PIB attributes of the physical layer PHY and phyCurrentChannel, macPANID of the MAC layer accordingly. If not, the node reinitiates the scan after a period of time.
(2) And sending an association request command.
The node sends an association request command to the network coordinator, and the network coordinator replies an acknowledgement frame (ACK) immediately after receiving the association request command, and simultaneously sends a connection indication primitive to its upper layer, indicating that a connection request of the node has been received. But this does not mean that a connection has been established, but only that the coordinator has received a connection request for a node. When the mac layer of the coordinator receives the connection indication primitive, it will decide whether to agree with the join request of the node according to its own resource condition (storage space and energy), and then send a response to the mac layer of the node.
(3) Waiting for the network coordinator to process.
After the node receives the ACK of the coordinator joining the association request command, the node mac waits for a period of time, and accepts the connection response of the network coordinator. If a connection response is received within a predetermined time, it announces this response to its upper layers. The network coordinator sets a waiting response time for the mac layer of the node to wait for the network coordinator to process the joining request command, if the resources of the network coordinator are enough, the network coordinator allocates a 16-bit short address to the node and generates a connection response command containing the new address and the connection success state, and the node can successfully establish a connection with the coordinator and can start communication. If the resources of the network coordinator are insufficient, the node to be added will resend the request information, and the direct network access is successful.
In the specific embodiment of the invention, the signal relay node is only communicated with the livestock delivery detection device meeting the preset corresponding relation through the second communication channel, so that the network establishment and joining processes are correspondingly simplified: the signal relay device is used as a ZigBee network coordinator and continuously transmits a beacon by utilizing a preset ZigBee channel; the preset ZigBee channels of adjacent signal relay devices are spaced apart from each other and predefined with the corresponding livestock delivery detection devices.
After sending the trigger signal, the livestock delivery detection device is used as a node in the ZigBee network to search the ZigBee network coordinator by utilizing the preset ZigBee channel scanning before sending the trigger signal next time; if the beacon is detected within the scanning period, an association request is sent to the ZigBee network coordinator to establish ZigBee network connection, and then the signal relay device and the livestock delivery detection device interact with detection information and control information.
Because the ZigBee communication channel or ZigBee network adopted in the specific embodiment of the present invention is different from the ad hoc network mode in the prior art to some extent, for example, the signal relay node only establishes connection and communication with the livestock delivery detection device meeting the preset correspondence, the signal relay node communicates with the livestock delivery detection device meeting the preset correspondence according to the preset channel, the preset channels of each adjacent signal relay node are distinguished from each other, and the like, which is a ZigBee network with "stricter", the networking flexibility is reduced, but the advantage is brought that:
(1) The network coordinator (signal relay node) has enough resources, the condition of insufficient resource allocation and the condition of reconnection generally do not occur;
(2) The network coordinator (signal relay node) adopts a preset channel to establish a network without considering the problem of channel conflict with surrounding network coordinators;
