A kind of security protection centralized control system based on ZigBeeTechnical field
The invention belongs to intelligent security-protecting and monitoring technical fields, and in particular to a kind of security protection centralized control system based on ZigBee.
Background technique
Existing most of security protection control systems for being used for family, are monitored only for all devices in family, can notCentralized control is carried out to each household family in entire cell or large buildings, and most of security protection control system needs nowWiring, and data transmission is low with treatment effeciency, leads to not to be transmitted to user in time and remind, causes damages.
Summary of the invention
In view of the deficiencies of the prior art, the present invention proposes a kind of based on CAN bus network and ZigBee-network, towards bigThe building of type and the security protection collection general control system of cell, are added ZigBee-network for household safety-protection equipment, with CAN fieldbusIn conjunction with realizing the intelligence control lump security protection intelligence control system an of large buildings.
In order to solve the above technical problems, the technical scheme adopted by the invention is as follows:
A kind of security protection centralized control system based on ZigBee, comprising: ZigBee-network, home gateway, the first CAN bus, the 2nd CANBus and concentration monitoring room, wherein
The home gateway is connected with the ZigBee-network, for whether just to judge the detection data in the ZigBee-networkOften；
First CAN bus is connected with multiple home gateways respectively, for distributing address to each home gateway,It determines data source, and receives the detection data in the ZigBee-network inputted through the home gateway simultaneously；
Second CAN bus is connected with first CAN bus, for acquire the detection data and with the detection dataThe address information of the corresponding home gateway；
The Centralized Monitoring room is connected with second CAN bus, for monitor the detection data in second CAN bus andAddress information, and wherein abnormal detection data is handled.
Further, the ZigBee-network includes: coordinator, router and security protection detection equipment, wherein the familyGateway is connected with the coordinator, and the coordinator is connected with multiple routers, and each router is connected with multipleSecurity protection detection equipment.
Further, establishing in the home gateway has parameter filter table, when the detection data of the security protection detection equipmentWhen not within the scope of the normal data in the parameter filter table, it will be connected with the ZigBee-network for being equipped with the security protection detection equipmentHome gateway address labeled as abnormal.
Further, the address information includes: labeled as abnormal home gateway address and normal home gatewayLocation.
Further, normal detection data and the normal home gateway corresponding with the normal detection dataAddress is periodically sent to the Centralized Monitoring room through second CAN bus.
Further, further includes: user client is wirelessly connected, for connecing with the Centralized Monitoring roomReceive the prompting of abnormal detection data.
Further, the security protection detection equipment includes: that combustible gas detection device, intrusion detection device and fire alarm detection are setIt is standby.
In another aspect of this invention, it is also proposed that a kind of monitoring method of security protection centralized control system as elucidated before, packetInclude following steps:
S1: whether the security protection detection devices collect data is simultaneously sent to the home gateway, judge detection data in the ginsengWithin the scope of normal data in number filter table: when the detection data is not within the scope of the normal data in the parameter filter tableWhen, by the home gateway address being connected with the ZigBee-network for being equipped with the security protection detection equipment labeled as exception, and will be different by thisNormal detection data is sent to first CAN bus；
S2: first CAN bus is by the detection data of the exception and abnormal family corresponding with the abnormal detection dataFront yard gateway address is sent to second CAN bus；
S3: the Centralized Monitoring room receives the abnormal detection data and abnormal home network in second CAN busAddress is closed, and the abnormal detection data is handled；
S4: the detection data real-time radio of the exception is sent to user client and reminded by the Centralized Monitoring room.
Further, the step S1 further include: when the detection data is in the normal number in the parameter filter tableWhen according in range, second CAN bus by normal detection data and it is corresponding with the normal detection data it is described justNormal home gateway address is periodically sent to the Centralized Monitoring room and carries out data statistics.
Beneficial effects of the present invention include at least:
1) present invention establishes mininet as unit of family, realizes centralized control by CAN bus, and in the reality for not influencing dataUnder the premise of when property and validity, multistage filtering, periodic report method solve Centralized Monitoring room big network Data Concurrent askTopic, improves transmission and the treatment effeciency of data；
2) indoor to use ZigBee wireless device, it is not necessarily to field wiring；
3) can PUSH message is to cell phone client in time, regardless of staying out, user can receive the exception information of push；
4) present invention docking cloud platform realizes long-range monitoring；
5) present invention combines CAN bus, have strong real-time, transmission range farther out, anti-electromagnetic interference capability it is strong, at low cost etc. excellentPoint realizes building intelligent control.

Specific embodiment
In order to make those skilled in the art more fully understand technical solution of the present invention, combined with specific embodiments below to thisInvention is described in further detail.The embodiments described below is exemplary, and for explaining only the invention, and cannot be understoodFor limitation of the present invention.Particular technique or condition are not specified in embodiment, according to the literature in the art described skillArt or condition are carried out according to product description.
According to an embodiment of the invention, Fig. 1 is ZigBee-network structural schematic diagram of the present invention, and it is shown referring to Fig.1, it is describedZigBee-network includes: coordinator, router and security protection detection equipment, wherein and the home gateway is connected with the coordinator,The coordinator is connected with multiple routers, and each router is connected with multiple security protection detection equipment.
According to an embodiment of the invention, Fig. 2 is security protection centralized control system structural block diagram of the present invention, and referring to shown in Fig. 2, the present inventionThe security protection centralized control system based on ZigBee, specifically includes that ZigBee-network, home gateway, the first CAN bus, the 2nd CANBus, Centralized Monitoring room and user client.
