Technical Field
[0001] This utility model belongs to the field of airport monitoring technology, specifically relating to a tower cabin device that supports remote adjustable air volume air knife and temperature-controlled glass heating. Background Technology
[0002] For remote airports, mosaic cameras are typically deployed in a centralized, high-point configuration, operating outdoors. Given the wide distribution of airports in my country and the diverse climates across different regions and seasons, high demands are placed on the reliability and stability of outdoor equipment. Therefore, a dedicated structural design is needed for the mosaic cameras to meet the angle requirements of each camera in panoramic stitching while providing comprehensive and intelligent protective features to ensure stable operation under various weather conditions, including rain, fog, snow, sandstorms, strong winds, and low temperatures.
[0003] Currently, the existing technology has designed a tower cabin with a frustum-shaped structure, with an installation platform on the inside for installing camera brackets and cameras to achieve 360-degree monitoring without blind spots; the bottom of the tower cabin is also equipped with a temperature-controlled semiconductor air conditioner to cool or heat the interior of the tower cabin under different temperature conditions.
[0004] The existing technology has the following problems and drawbacks:
[0005] 1. Glass windows are easily affected by rain, snow, and dust, and over time water stains or dust accumulation will appear. In areas with good ecology, glass windows are also easily blocked by mosquitoes.
[0006] 2. In autumn and winter or in some cold regions, glass windows are easily blocked by frost, freezing rain, and freezing snow; when there is a large temperature difference between the inside and outside of the cabin and the ambient humidity is high, the glass windows are prone to fogging.
[0007] However, the aforementioned truncated cone-shaped tower cabin only provides a relatively stable ambient temperature for the interior space of the tower cabin through temperature-controlled semiconductor air conditioning, which cannot effectively solve the above problems. As a result, the environmental adaptability and regional adaptability of the tower cabin are generally poor, and it cannot cope with complex natural conditions. Summary of the Invention
[0008] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a tower chamber device that supports remote adjustable air volume air knife and temperature-controlled glass heating, so as to solve the problems in the prior art where the glass window is easily blocked by rain, snow, dust and mosquitoes, and the glass window is easily affected by frost, freezing rain, freezing snow or fog.
[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0010] This utility model discloses a tower chamber device that supports remote adjustable air volume air knife and temperature-controlled glass heating, comprising: tower chamber body, air compressor, air tank, reducing tee, pressure reducing valve, pneumatic control valve, DC power supply, regulator, programmable controller, air distribution valve, control terminal, electrically heated glass, air knife, temperature transmitter, push button switch and selection button;
[0011] The air compressor's output port is connected to the air tank's input port. The air tank's output port is connected to the input port of a reducing tee via a hose. The first output port of the reducing tee is connected to the input port of a pneumatic control valve via a hose. The second output port of the reducing tee is connected to the input port of a pressure reducing valve via a hose. The pressure reducing valve's output port is connected to the pneumatic control input port of the pneumatic control valve via a hose. The pneumatic control valve's signal control terminal is connected to the regulator's signal output terminal and the programmable controller's analog output terminal, respectively. The pneumatic control valve's output port is connected to the input port of a distribution valve via a hose. The distribution valve's multi-port output ports are connected to multiple [other valves / ports] via hoses. The air knife has an input port; the air distribution valve, electrically heated glass, air knife, and temperature transmitter are all located in the tower body; a DC power supply powers the pneumatic control valve, regulating valve, programmable controller, electrically heated glass, and temperature transmitter; the DC power input terminal of the electrically heated glass is connected to the output terminal of the push-button switch, the output terminal of the relay in the programmable controller, and the external power supply terminal; the input terminal of the push-button switch and the input terminal of the relay in the programmable controller are connected to the two output terminals of the selector switch, and the input terminal of the selector switch is connected to the external power supply terminal; the programmable controller also communicates with the control terminal via a network cable.
[0012] Furthermore, the live wire of the DC power supply used for the electrically heated glass is connected to the output terminal of the push-button switch and the relay output terminal in the programmable controller, respectively, and the neutral wire of the DC power supply is connected to the neutral wire of the external power supply. The neutral and live wires of the DC power supply used for the programmable controller are connected to the external power supply, respectively, and the positive and negative terminals of the DC power supply are connected to the positive and negative terminals of the programmable controller's power supply, respectively. The programmable controller also communicates with the control terminal via a network cable.
[0013] Furthermore, the positive terminal of the analog input terminal of the programmable controller is connected to the negative terminal of the temperature transmitter, the positive terminal of the temperature transmitter is connected to the positive terminal of the DC power supply output, and the negative terminal of the DC power supply output is connected to the negative terminal of the analog input terminal of the programmable controller.
[0014] Furthermore, the number of electrically heated glass pieces is several, and the positive and negative terminals of each electrically heated glass piece are connected in parallel to the output terminal of a DC power supply.
[0015] Furthermore, the selector switch switches the circuits of the push-button switch and the programmable controller to ensure that only one circuit is powered at any given time.
[0016] Furthermore, the gas distribution valve is fixed to the top of the tower body by a bracket, and the hose connected to the output port of the gas distribution valve is connected to each air knife along the outer wall of the tower body. A U-shaped iron plate is fixed on the outer wall of the tower body to fix the hose. The electrically heated glass is embedded in the glass window installed on each tower body and is clamped and fixed by two bent frames. The air knife is fixed above the glass window on each tower body by an adjustable angle structure. The temperature transmitter is installed on the upper half of the inner wall of the tower body by a stainless steel clamp.
[0017] In this invention, the pneumatic control valve can be remotely controlled by sending commands through a regulator, or by sending commands to a programmable logic controller (PLC) via a control terminal, which then sends analog signals to the pneumatic control valve to achieve remote control. These two methods are redundant, improving the reliability of remote air volume regulation.
[0018] In cases of heavy rain or snow, a high-flow-rate purging method is required to quickly remove water droplets or snowflakes. By sending corresponding instructions through the regulator or programmable controller, the pneumatic control valve opens the pneumatic control input port. The gas in the gas tank passes through the reducing valve after passing through the reducing valve and then enters the pneumatic control input port, thereby increasing the gas volume and increasing the valve opening of the pneumatic control valve, thus increasing the flow rate through the valve.
[0019] In situations requiring dust accumulation or insect repellent, a low-flow purging method can be used to avoid unnecessary consumption and extend the lifespan and maintenance cycle of the air compressor. By sending corresponding commands through a regulator or programmable controller, the pneumatic control valve opens its pneumatic control output port, discharging a certain amount of air, thereby reducing the valve opening and decreasing the flow rate through the valve.
[0020] When the required flow rate of the air knife remains constant, there is no need to control the pneumatic control valve or continuously supply air to it; the valve opening remains unchanged.
[0021] The number of air distribution valves is selected according to the number of air knives, and the air distribution valves are connected in series through hoses.
[0022] Among them, the electric heating glass adopts double-layer tempered glass laminated resistance heating. The positive and negative electrodes of the electric heating glass are sealed in the glass interlayer with glue and led out from the upper and lower sides of the glass. They are connected in parallel to the power supply trunk line inside the tower body. The power supply trunk line is laid around the cable tray on the inner wall of the tower body and then connected to the DC power output terminal.
[0023] The DC power supply has a 220V input. The neutral wire is connected to the neutral wire of the external power supply. Two live wires are connected to the output of the push-button switch and the output of the relay in the programmable controller, respectively. The live wires of the push-button switch input and the relay input in the programmable controller are connected to the two outputs of the selector switch, which switches between them. Only one line is energized at any given time. The input of the selector switch is connected to the live wire of the external power supply.
[0024] The temperature transmitter is fixed on the inner wall of the tower body. The positive terminal of the analog input terminal of the programmable controller is connected to the positive terminal of the temperature transmitter, the negative terminal of the temperature transmitter is connected to the positive terminal of the DC power supply output, and the negative terminal of the DC power supply output is connected to the negative terminal of the analog input terminal of the programmable controller.
[0025] The temperature transmitter collects the real-time temperature inside the tower compartment and converts it into an analog signal, which is then transmitted to the programmable controller. The programmable controller communicates with the control terminal via a network cable, and the control terminal controls the programmable controller to set the temperature threshold for turning the electric heating function of the electric heating glass on or off.
[0026] Turn the selector switch to the live wire of the relay input terminal in the programmable controller. When the programmable controller detects that the temperature collected by the temperature transmitter has reached the temperature required to turn on or off the glass electric heating, it controls the output terminal of the relay to turn on or off the DC power supply, thereby turning the electric heating of the glass on or off.
[0027] The beneficial effects of this utility model are:
[0028] 1. This utility model addresses the problem of glass windows being easily obstructed by rain, snow, dust, and insects. It designs an air blade to blow clean the outer surface of the glass window, preventing rain, snow, dust accumulation, or insects from obstructing or interfering with the camera's view. Simultaneously, a remotely adjustable pneumatic control valve allows for flexible adjustment of the airflow rate. For different scenarios, a high-flow rate can be used in heavy rain or snow to quickly remove water droplets or snowflakes; while a low-flow rate can be used to prevent dust accumulation and repel insects, avoiding unnecessary consumption, extending the lifespan and maintenance cycle of the air compressor, and generating certain economic benefits.
[0029] 2. This utility model addresses the issue of glass windows being easily blocked by frost, freezing rain, and snow during autumn and winter or in some cold regions. It features a temperature-controlled electric glass heating system that automatically activates in low-temperature conditions to prevent these problems. Furthermore, the electric glass heating system supports remote manual control. In situations where temperature control is not suitable, such as high humidity in summer and large temperature differences between the inside and outside of the cabin, fogging can easily occur; in such cases, manual activation of the electric heating system can be used to defog the windows.
[0030] In summary, this invention effectively improves the environmental adaptability of the tower, provides a good environment for the stable and reliable operation of the camera, and facilitates remote operation, avoiding the waste of time and manpower in on-site operation.

[0043] In cases of heavy rain or snow, a high-flow-rate purging method is required to quickly remove water droplets or snowflakes. By sending corresponding instructions through the regulator or programmable controller, the pneumatic control valve opens the pneumatic control input port. The gas in the gas tank passes through the reducing valve after passing through the reducing valve and then enters the pneumatic control input port, thereby increasing the gas volume and increasing the valve opening of the pneumatic control valve, thus increasing the flow rate through the valve.
[0044] In situations requiring dust accumulation or insect repellent, a low-flow purging method can be used to avoid unnecessary consumption and extend the lifespan and maintenance cycle of the air compressor. By sending corresponding commands through a regulator or programmable controller, the pneumatic control valve opens its pneumatic control output port, discharging a certain amount of air, thereby reducing the valve opening and decreasing the flow rate through the valve.
[0045] When the required flow rate of the air knife remains constant, there is no need to control the pneumatic control valve or continuously supply air to it; the valve opening remains unchanged.
[0046] The number of air distribution valves is selected according to the number of air knives, and the air distribution valves are connected in series through hoses.
[0047] Among them, the electric heating glass adopts double-layer tempered glass laminated resistance heating.
