Fig. 1 is the monitoring system of controller switching equipment of the present invention.
Embodiment
The monitoring system that a kind of controller switching equipment is provided of the present invention has low cost, the characteristics of high reliability.
Further describe the technical scheme of this patent below in conjunction with accompanying drawing:
As shown in Figure 1, the invention provides a kind of monitoring system of controller switching equipment, comprise: at least one monitoring equipment, monitoring equipment in the present embodiment comprises monitoring equipment 21, monitoring equipment 22, monitoring equipment 23, monitoring equipment 24, monitoring equipment 25 and monitoring equipment 26, is used for the data of monitoring controller switching equipment; Monitoring front end processor 3 is by communication and the Monitoring Data that receives the monitoring equipment transmission; Monitor server 1 receives the Monitoring Data that described monitoring front end processor 3 sends.
Monitoring equipment comprises: information acquisition unit, for the analog signal data that gathers controller switching equipment; Data processing unit is used for the analog signal data that collects is converted to digital signal; Radio communication unit is used for receiving the digital signal of adjacent monitoring equipment, and the digital signal of self monitoring equipment and the adjacent monitoring equipment that receives is sent to monitoring front end processor or adjacent monitoring equipment; Power subsystem is used to monitoring equipment that power supply is provided.
Wireless communication unit is made of wireless transceiver and relay router, is responsible for carrying out radio communication with other monitoring equipments, and exchange of control information and transmitting-receiving image data are sent in the information data multi-hop with self and adjacent monitoring terminal and forward monitor server to; The transistroute function can realize the advantage of wireless data multi-hop transmission transfer, can pass through the barriers such as floor and wall, can also prolong monitoring equipment simultaneously and dispose scope; Power unit then adopts minicell usually, for the operation of sensor node provides institute's energy requirement.
By adopting relay router, the present invention has adopted based on the impact of route redundancy algorithm by the reduction chain rupture, has reduced the Route establishment process and has promoted intranet security, replenishes its deficiency.Redundant multipath can reduce the impact of chain rupture, has reduced the Route establishment process.Malicious intrusions wants to hinder data and transmits, and need to all have a malicious node at least on every paths, can effectively reduce the probability that the Zigbee network internal node is attacked like this.Even internal node if not on selected path, can not obtain the complete information of communication node, is initiated any attack degree-of-difficulty factor and all will be increased, therefore has higher fail safe.
Data are electric parameter and/or the environmental parameter of controller switching equipment.
What radio communication unit adopted carries out communication for the Zigbee agreement.Radio communication unit adopts 128 AES cryptographic algorithm to be encrypted when communication.
Wireless Zigbee private network is to meet the wireless communication technology of IEEE802.15.4 requirement under 2.4GHz, has realized the MANET mode of dynamic routing, has avoided losing of data message.
The zigbee network has safety guarantee function and has:
(1) refresh function: refresh the attack that inspection can stop forwarding, monitoring equipment keeps input and defeated refresh counter, and when a new Key Establishing was arranged, counter just reset.
(2) packet integrity checking function: in the transmission course, this function stops the assailant to cause the invasion formula to make amendment to data.The integrality option has 0,32,64 or 128, the selection of compromising between data protection and accessing cost for data.
(3) authentication function: authentication has guaranteed the originating end source of data, stops the assailant to revise a device data and imitate another equipment.Authentication can be applicable to network layer and mechanical floor, and the network layer authentication mechanism is by being by using a public netkey, and this has stoped outside attack, its advantage be memory cost seldom.The mechanical floor authentication mechanism is the unique link key of use between 2 equipment, and its advantage is can stop inside and outside attack simultaneously, but needs very high memory cost.
(4) encryption function: stop listener-in's interception data.It uses 128 AES cryptographic algorithm, and this encipherment protection can be applicable to network layer and data-link equipment layer L.Network layer encryption is by using a public netkey, and this has stoped outside attack, and memory cost seldom.It is to use unique link key between 2 equipment that mechanical floor is encrypted, and can stop inside and outside attack, but need very high memory cost.The Zigbee technology can be used 3 kinds of basic keys in data encryption process, be respectively master key, link key and netkey.Master key is the basis of 2 equipment long-term safety communications, also can be used as general link key and uses.So, must safeguard confidentiality and the correctness of master key.Link key is shared by 2 equipment in a Zigbee network, and it can be set up by master key, also can install when device fabrication, and it can be applicable to data link layer.Netkey is applied in, network layer, and application layer link key and netkey constantly periodically upgrade on request.
When implementing, each monitoring equipment not only itself can be monitored the grid equipment object, as connect the transducers such as intelligent electric meter, Temperature Humidity Sensor, water sensor, directly carry out data acquisition and monitoring, automatically transfer and converge other adjacent monitoring equipment and pass the data message of coming, in addition, each monitoring equipment also can be in the scope that own signal covers, and a plurality of other isolated monitoring equipment wireless connections of not bearing network information transfer task.
The function that monitor server possesses Analysis on monitoring data, alarm and checks in good time among the present invention, support forms the dedicated network of Utilities Electric Co. inside.The interconnection of a plurality of Zigbee networks, whole monitoring network can be supported tens transducers and controlled plant, thereby have satisfied that many monitoring terminals of intelligent grid type class is many, zonule or the large requirement of film micro area monitoring of equipment quantity.
Among the embodiment of the present invention, the monitoring main station system can be seen the communications status of wireless communication link at any time, and extended capability is strong, and easy construction has finely been satisfied professional highly reliable, the cheaply transfer of data requirement of monitoring.Simultaneously, this wireless private network transmission equipment is easy to use, installation cost is lower, simple in structure, design science is reasonable, lightweight, volume is little, maintenance maintenance is convenient and cost is lower, is a kind of safe and reliable transmission equipment.
The present invention will reach following technique effect after adopting technique scheme:
1. polymorphic type in a kind of electric power system, zonule or film micro area monitoring of equipment Telecommunication network are provided, solve the many and long problem that causes the communication decay of communication distance of terminal monitoring device category;
