Description
Technical field
This utility model is related to prison monitoring field, more particularly, to a kind of prison video monitoring system.
Background technology
Less radio-frequency is a kind of contactless automatic identification technology, and it passes through radiofrequency signal automatic identification destination object,
Item tracing data exchange can rapidly be carried out.Identification work, without manual intervention, is operable with various adverse circumstances.Wirelessly
Radio-frequency technique can recognize that high-speed moving object and can identify multiple labels simultaneously, swift and convenient to operate.Wireless radio-frequency is born
During World War II, it is the successor of traditional bar code technology, is also called " electronic tag ".
The basic functional principle of wireless radio-frequency is simultaneously uncomplicated：After label enters magnetic field, what reception plug-in reader sent penetrates
Frequency signal, sends out storage product information in the chips by the energy that faradic current is obtained（Passive label or passive mark
Sign）, or the signal actively being sent a certain frequency by label（Active Tag, active label or active tag）, plug-in reader reading
Win the confidence breath after decoding, deliver to CIS and carry out relevant data processing.
The radio frequency system of complete set, is soft by reader and electronic tag i.e. so-called transponder and application
Three parts of part system are formed, and its operation principle is the radio wave energy that Reader launches a characteristic frequency, in order to drive
Internal data is sent by circuit, now Reader just received in sequence unscrambling data, gives application program and does corresponding process.
With generally permissible from the point of view of the communication between less radio-frequency card reader and electronic tag and energy-sensitive mode
It is divided into：Inductively and back scattering couple two kinds.The less radio-frequency of general low frequency mostly adopts the first formula, and higher-frequency is big
Adopt the second way more.
Reader is different with technology according to the structure using can be to read or read/write device, be radio frequency system information
Control and processing center.Reader is generally made up of coupling module, transceiver module, control module and interface unit.Reader and
Typically enter row information using half-duplex operation mode between transponder to exchange, reader carries by being coupled to passive balise simultaneously
Energizing quantity and sequential.In actual applications, Ethernet or WLAN etc. can be passed through further to realize object identification information is adopted
The management functions such as collection, process and teletransmission.Transponder is the information carrier of radio frequency system, and transponder is by coupling mostly
Original paper（Coil, microstrip antenna etc.）Form parasitic element with microchip.
Less radio-frequency has following Performance Characteristics：
1. quickly scan, radio frequency identification device can recognize the several radio frequency labels of reading simultaneously.
2. volume miniaturization, various shapes, less radio-frequency is not limited with shape by size on reading, and is not required to
Coordinate fixed dimension and the press quality of paper in order to read degree of accuracy.Additionally, radio frequency label more can toward miniaturization with
Various Form Development, to be applied to different product.
3. contamination resistance and durability, the carrier of conventional barcode is paper, is therefore easily contaminated, but wirelessly penetrates
Frequency has very strong repellence to materials such as water, oil and chemical drugss.Further, since bar code is attached to plastic bag or overwrap
On case, so being particularly susceptible to lose；Less radio-frequency label is to deposit in the chips by data, therefore can be against being stained.
4. reusable, bar code printing now just cannot be changed up afterwards, and radio frequency label then can weigh
Increase, change, deleting the data of storage in less radio-frequency label again newly, facilitating the renewal of information.
5. penetrance and no barrier are read, and in the case of capped, less radio-frequency can penetrate paper, timber and plastics
Etc. nonmetallic or nontransparent material, and penetrance communication can be carried out.And bar code scanner must closely and also do not have
In the case of having object to stop, just can distinguish wanding.
6. the memory capacity of data is big, and the capacity of one-dimensional bar code is 50Bytes, and the maximum capacity of two-dimensional bar can store up
Deposit 2 to 3000 characters, the maximum capacity of less radio-frequency then has the development with memory carrier for several MegaBytes., data capacity
Also there is the trend of continuous expansion.The data quantity carrying needed for following article can be increasing, and label can be expanded with the need of capacity
Ask and also accordingly increase.
7. safety, due to less radio-frequency carry is electronic type information, its data content can via cryptoguard so as to
Content is difficult to be forged and alters.The characteristics such as remote reading that less radio-frequency possesses because of it, high storage capacity and get most of the attention.
It not only can help an enterprise that the efficiency of goods, information management is greatly improved, and can also allow sale enterprise and manufacturing enterprise
Interconnection, thus more accurately receiving feedback information, demand for control information, optimizes whole supply chain.
Existing prison monitoring system generally rely on traditional electronic warning station for example video monitoring system, warning system,
Gate control system, this seems at complicated scene and is difficult for independent, even multiple system is applied simultaneously, very multi-functional
Dynamic combination above can not accomplish seamless combination, because monitoring camera is excessive, limited police strength cannot monitor each people that serves a sentence simultaneously
The immediate status of member, the quantity of information faced by prison officer is excessive it is impossible to real-time grasp each controlled area prison in prison
The details of convict and number, cause some potential safety hazards to highlight.
Also there are some prison monitoring systems to employ bracelet that convict is positioned, but convict can not be prevented by bracelet
Disassemble.
