A type fixed hard intelligent isolation fence is an intelligent isolation fence based on a UWB electronic tag microcontroller. The micro-controller based on the UWB electronic tag is short in charging time and high in cruising ability, can be continuously used for 4-6 months under the condition of 5000mA of the lithium battery, obtains the electric quantity condition of the battery in real time through a passenger flow management and control terminal system, has a low-electric-quantity reminding function, and can be repeatedly used after the replaced battery is charged when the electric quantity is lower than a certain value. When the intelligent isolation fence is installed, the microcontrollers based on the UWB electronic tags are vertically fixed on the intelligent isolation fence, the joints are reinforced by adopting non-conductor firmware, and in addition, a protective cover is installed for each microcontroller in a matched mode. Fig. 2 is a design plan view of an a-type fixed hard intelligent isolation fence with a UWB positioning function, wherein two microcontrollers based on UWB electronic tags are respectively installed at the left and right parts of the isolation fence.

The device is mainly characterized in that the hard isolation rod on the isolation fence can automatically extend out or retract, the base is movably connected with the vertical rod, the device has an automatic rotation function, and the direction of the hard isolation rod can be conveniently adjusted to switch different passenger flow dispersion management and control routes. For type B intelligent isolation barriers, the charging and endurance efficacies of a microcontroller based on a UWB electronic tag are the same as those of type A isolation barriers. Fig. 3-4 are schematic diagrams of B-type intelligent isolated column with UWB positioning function, wherein the core working elements are an electro-hydraulic rod and a microcontroller based on UWB electronic tags. Including base 1, stand 2, hydraulic stem driving motor 5, a plurality of isolation rod 3, a plurality of electronic hydraulic stem 4, based on UWB electronic tags's microcontroller 6 and rotation motor 7. The upright post is provided with a plurality of isolating rods, one end of each isolating rod is connected to the upright post, and an electric hydraulic rod is arranged between the upright posts. In one embodiment the spacer rods are two, the electro-hydraulic rods are two, and the spacer rods are positioned 180 ° from each other after horizontal opening. The number of the isolation rods is set according to the requirement, and the isolation rods can be 1, and also can be 4, which are symmetrically arranged at an angle of 90 degrees. The isolation rod is a hard isolation rod, and the length of the isolation rod is 80-200 cm. The hydraulic rod driving motor drives the electric hydraulic rod to compress or stretch; when the electric hydraulic rod is compressed, the isolating rod sags and retracts, and when the electric hydraulic rod is stretched, the isolating rod is driven to be in a horizontal opening state, so that an isolating function is realized. The connection between the electric hydraulic rod and the upright post and between the electric hydraulic rod and the isolating rod are rotatable round buttons and are connected through bearings, and the purpose of the design is that when the electric hydraulic rod is stretched, the hard isolating rod is enabled to realize corresponding mechanical action through the connection of the rotatable round buttons.
The microcontroller 6 of the electronic tag continuously transmits data frames with repetition of UWB pulses, these UWB bursts being received by the positioning base station. Each base station measures the time of a data frame of each microcontroller based on a UWB electronic tag to reach a receiver antenna by using a high-sensitivity short pulse detector, the passenger flow management and control terminal refers to calibration data sent by the microcontroller, the time difference of the microcontroller reaching different positioning base stations is determined, the position of the microcontroller is calculated, namely the position of the intelligent isolation fence is found, and therefore the positioning of the intelligent isolation fence is achieved. A microcontroller 6 of the electronic tag receives the control signal sent by the passenger flow management and control terminal, and controls the hydraulic rod driving motor to drive the electric hydraulic rod to compress or stretch based on the control instruction; when the electric hydraulic rod is compressed, the isolating rod sags and retracts, and when the electric hydraulic rod is stretched, the isolating rod is driven to be in a horizontal opening state. And receiving a rotation instruction sent by an upper computer, and controlling a rotating motor to drive the upright post to rotate around the axis of the upright post.

All the electric hydraulic rods can be driven by one motor, and each electric hydraulic rod can also correspond to the driving motor respectively, so that each isolating rod can be controlled independently.
Preferably, a manual switch is further arranged and used for manually controlling the hydraulic rod driving motor to drive the electric hydraulic rod to compress or stretch.
The hard isolation rod on the B-type intelligent isolation fence can automatically extend out or retract, the base is movably connected with the vertical rod, an automatic rotating function is achieved, and the direction of the hard isolation rod is convenient to adjust so as to switch different passenger flow dispersion management and control routes. In addition, under emergency, such as fire alarm or terrorist attack, the electric hydraulic rod can be quickly restored to a compressed state through the instruction sent by the passenger flow management and control terminal, the hard isolation rod is retracted, the isolation function of the isolation fence is removed, and passengers can be evacuated in the shortest time. When the passenger flow management and control route needs to be changed under some special conditions, the direction of the hard isolation rod can be changed by rotating the vertical rod, so that different management and control routes can be adjusted to meet the requirements of the conditions. Since the isolation fence usually needs to be folded only in emergencies or special cases, the required power supply times are very few, and the power consumption is not needed in general cases, so the overall power consumption is low.
The C-type intelligent isolation fence is an intelligent isolation fence which realizes the isolation effect by utilizing the combined action of a microcontroller based on a UWB electronic tag and a direct-current push-pull electromagnet.
With reference to fig. 5, the device comprises a base 2-1, a column 2-2, a bump 2-3, a telescopic belt 2-4, an electromagnet 2-5 and a microcontroller 2-6 based on a UWB electronic tag;
the base 2-1 is used for supporting the upright post 2-2; the base may be a disc, rectangular block, or the like, providing stable support for the upright 2.
A plurality of lugs 2-3 are arranged on the upper part of the upright post 2-2 along the circumferential direction; the lug is provided with a slide rail, the buckle is provided with a slide groove, and the slide groove is vertically inserted and positioned along the slide rail. In one embodiment, the number of the lugs is 4, and the lugs are evenly distributed along the circumferential direction of the upright column.
One end of the telescopic belt is fixed to the upright post, the other end of the telescopic belt is provided with a buckle, the buckle is matched with the lug, and the telescopic belt of one isolation fence is fixed to the lug of the other isolation fence through the buckle to realize cascade connection of the isolation fences; the telescopic band is an elastic band, the elastic band retracts and winds to the inside of the stand column under the action of elastic force after unlocking, and the buckle is exposed outside the stand column.
The electromagnet moves up and down after being electrified to drive the buckle to be separated from the convex block, so that unlocking between the two isolation fences is realized. With reference to fig. 6-7, in one embodiment, the electromagnet is a dc push-pull electromagnet, and moves vertically upward, and is disposed below and outside the protrusion, and corresponds to the position of the buckle after connection.
And the micro controllers 2 to 6 based on the UWB electronic tags receive the control signals sent by the passenger flow management and control terminal and control the electromagnet to move after being electrified based on the control instructions.
Furthermore, a manual switch can be arranged for manually controlling the electromagnet to move up and down.
If the isolation fence is in a working state of isolating passenger flow, the convex block of the other isolation fence is vertically inserted downwards through the buckle of the telescopic belt, and at the moment, two adjacent isolation fences are connected through the telescopic belt to play a role in isolating passenger flow; when the isolation function of the isolation fence needs to be released, the buckle of the telescopic belt needs to be separated from the convex block, and the telescopic belt is in a retraction state. The telescopic band is fixedly connected with the buckle, the buckle can be vertically downwards inserted into one of the 4 lugs in different directions at the top of the isolation fence, and the buckle and the direct-current push-pull electromagnet are designed to meet the requirement that after the buckle is inserted, the slide rod of the push-pull electromagnet can push the buckle out of the lug after moving, so that the buckle is separated from the vertical rod.

For the C-type intelligent isolation fence, the charging and endurance effects of the microcontroller based on the UWB electronic tag are the same as those of the A-type isolation fence.
The A-type isolation fence belongs to a fixed type hard isolation fence, and is used for dredging routes with large range and longer communication area due to the characteristics of large volume, heavy weight and difficulty in moving, and is particularly suitable for occasions where the dredging routes are not easy to change. The B-type and C-type isolation fences belong to adjustable isolation fences, and the adjustable isolation fences are suitable for the inlet and outlet of a dredging route by virtue of the advantages of strong flexibility, small volume, easy movement and easy extension, and can also be used at the curve part of a transfer line to achieve the purpose of flexibly changing the curve route. In addition, considering emergency, the adjustable intelligent isolation fence can automatically shrink the isolation belt or retract the isolation fence, so that the requirement of rapid evacuation of passengers is met.
