Description
Technical Field
The invention discloses a sidewalk system easy to deice, and particularly relates to an improvement aspect of a deicing structure design of the sidewalk system.
Background
When the temperature is lower than zero degrees centigrade in winter, particularly in the regions with much water in the south, roads are easy to freeze, great inconvenience is brought to the trip of people, vehicles and pedestrians are blocked to pass, and traffic accidents are easy to cause. So that the road is usually deiced in winter. Typical methods of deicing include mechanical deicing, spreading of snow-melting agents, thermal deicing.
The methods have the advantages and the disadvantages that when the pavement is deiced, the pavement is relatively narrow and blocked by greening trees, large deicing equipment cannot play a role, and the snow-melting agent has too high salt content and can generate adverse effects on peripheral greening and water environment. The harm is reduced by adopting a snow melting agent and an artificial deicing method.
On the other hand, when a snow melting agent and manual deicing are adopted for a frozen sidewalk or deicing operation is carried out, the ice layer is formed by water freezing and is tightly combined with the road surface, the road surface is easily damaged by mechanical deicing, and the later repair is time-consuming and labor-consuming.
The key to solving this problem is the control of the road surface temperature and the drainage of the accumulated water. If the ice layer can be easily removed by heating the road surface in time after freezing to melt and destroy the ice layer and separate the ice layer from the road surface. If ponding can discharge again, then there is not ponding on the road surface, has just reduced the possibility of icing again.
Disclosure of Invention
The pavement can adopt a material with a water permeable function as a surface layer due to no rolling of heavy vehicle machinery so as to achieve the function of water drainage, and the pavement system cannot control the temperature of a road surface due to the absence of a temperature control device, so that the deicing operation cannot be realized.
In order to achieve the purpose, the invention adopts the following technical scheme:
the invention discloses a sidewalk system easy to deice, which is characterized in that: comprises a surface layer, a hydrophobic base layer, a temperature sensor, a heating grid and a controller module; the surface layer is provided with a porous structure, and liquid can permeate into the hydrophobic base layer through the surface layer; the hydrophobic base layer has a drainage function, and liquid is drained into a drainage system through the hydrophobic base layer; the temperature sensors are sequentially arranged below the surface layer at intervals and on the right side of the heating grid, and the temperature sensors are connected with the controller module through data lines; the heating grid is positioned in the leveling layer of the hydrophobic base layer below the surface layer and is connected with the controller module through a lead.
In the invention, the heating grids are in a grid shape and are multiple, the surface layer is made of heat conduction materials, and the interior is provided with an electric heating component.
In the invention, the electric heating component in the heating grid can be a resistance wire made of alloy materials or a PTC ceramic electric heating component.
In the invention, the controller module can be welded with one or a combination of a plurality of components of a key switch, a wireless communication module and a measurement and control component on a control panel thereof, and is used for controlling the working state of the system.
The manner of opening and closing the heater grid is different according to the type of the controller module:
the controller module is provided with a key switch, so that the on-off of the heating grid is controlled by a mechanical switch;
the wireless communication module is in remote communication control with the external control component, and the power on and off of the heating grid is controlled by the external control component;
the controller is provided with a measurement and control component, so that the on-off of the heating grid is controlled by the measurement and control component on the controller module;
if the combination of various components exists, the priority order is that the mechanical switch has priority over the measurement and control component, and the measurement and control component has priority over the wireless communication module.
The invention has the beneficial effect that the ice layer of the sidewalk can be easily removed.

Detailed Description
The invention will be described in detail with reference to the drawings and specific embodiments, which are illustrative of the invention and are not to be construed as limiting the invention.
Example (b):
a walkway system that is susceptible to deicing, characterized by: the device comprises a surface layer 1, a hydrophobic base layer 2, a temperature sensor 3, a heating grid 4 and a controller module 5; the surface layer 1 has a porous structure, and liquid can permeate into the hydrophobic base layer through the surface layer; in the example, the surface layer 1 is a water permeable brick layer, the hydrophobic base layer 2 has a drainage function, and liquid is drained into a drainage system through the hydrophobic base layer; the top of the hydrophobic base layer is a leveling layer 201, the temperature sensor 3 and the heating grid 4 are both buried between the leveling layer 201 of the surface layer 1 and the hydrophobic base layer 2, and the leveling layer 201 in the example is sand with the particle size of 0.3-5 mm.
The temperature sensors 3 are sequentially and alternately positioned below the surface layer 1 and on the right side of the heating grid 4, the temperature sensors 3 are used for sensing the working state of the heating grid 4 and transmitting electric signals to the controller module 5 through data lines, and temperature values are calculated by a program burnt in the control module 5.
In this example, the controller module 5 is provided with a plurality of key switches 501 on the housing, wherein the key switches 501 are connected to the controller module 5 through data lines, and each key switch 501 corresponds to one heating grid 4; in addition, the controller module 5 is also provided with a wireless communication module as an external input for the controller module 5 to communicate with an external control component.
In this example, therefore, the operation of the heater grid 4 is controlled by a combination of two control modes, namely, a push switch 501 on the controller module 5 and a wireless communication module. The output end of the wireless communication module and the output end of the key switch 501 are both connected to the IO port of the controller module 5. In this example, the wireless communication module is a communication module based on a 4G network and a service system thereof.
The keyswitch 501 is connected in series between the high level and the IO port. Initial state: the key switches are all in the off state, the heater grid 4 does not work, and the control program C0 of the controller module 5 to the heater grid 4 works as follows:
s1: reading the level state of the IO port corresponding to the key switch 501, controlling the corresponding heating grid 4 to start working if the key switch 501 is pressed down, stopping heating if the key switch 501 is disconnected, and then sequentially executing S2;
s2: and reading the output of the wireless communication module, controlling the corresponding heating grille 4 to start or stop heating after reading the heating or stopping instruction, and not acting if no instruction exists.
In the process of executing S2, the key switch 501 is turned on or off to execute the corresponding procedure of S1.
The heating grids 4 are positioned in the leveling layer 201 between the hydrophobic base layers 2 below the surface layer 1 and are connected with the controller module 5 through leads. The heating grids 4 are in a grid shape and are multiple, the surface layers are made of heat conduction materials, the interior of each heating grid is provided with an electric heating assembly, alloy resistance wires are arranged inside the heating grids 4 in the example, and heat conduction ceramics are arranged outside the heating grids. Setting the threshold value of the internal temperature to 10 degrees centigrade

The internal program of the CPU module on the controller module 5 after power-on executes the following steps:
s1: a control program C0 for the heater grid 4 executed by the controller module 5;
s2: and sequentially reading the temperature values measured by the temperature sensors between the leveling layer 201 and the surface layer 1, controlling the corresponding heating grids 4 to stop working when the temperature values exceed a threshold value (10 ℃), and continuing heating when the temperature values do not exceed the threshold value.
The heating routine in S1 executes the following steps:
the control module 5 outputs PMW chopped waves to the heating grids 4 through the I/O port, controls the resistance wires in the corresponding heating grids 4 to heat until the threshold temperature (10 ℃) is reached, and starts the heating program again when the temperature is lower than the threshold temperature.
After the embodiment is implemented, even if the sidewalk is covered with snow, the heating grid 4 is used for continuously heating, and heat is conducted to the surface of the sidewalk to melt the snow ice layer. The melted water is not accumulated above the surface layer 1 but is discharged into a sewer system.
