TECHNICAL FIELD
[0001] The utility model relates to the field of ship intelligent control, especially to a ship's bridge inside visual field intelligent control system and ship. BACKGROUND
[0002] When driving a ship, the driver usually observes the visual field of the driving direction through the front windshield of the ship's bridge, so the visual field of the driving direction is very important, and therefore the front windshield and other windows of many ship's bridges are made of large-area glass to improve the driver's visual field.
[0003] However, since the ship is driven on the lake, river or sea, especially in winter, the water surface is cold, humid or has a large temperature difference, which can easily cause the glass to produce fog or dew, thereby blocking the driver's visual field and affecting the driver's visual field and endangering the safety of navigation. The existing de-fogging methods include manual methods or adding de-fogging devices, such as a portable ship's bridge glass window de-fogging device with patent application number 201820011555.X, which includes a fourth flushing water pipe, a fourth water pipe support frame, a second roof de-fogging device, a main water pipe support frame, a first roof de-fogging device, a first water pipe support frame, a water droplet pipe type de-fogging device, a first flushing water pipe, a third flushing water pipe, a folding device, the lower part of the fourth flushing water pipe is connected to the upper part of the fourth water pipe support frame, the lower part of the fourth water pipe support frame is installed on the upper part of the second roof de-fogging device, the two sides of the second roof de-fogging device are welded to the inner side of the second roof de-fogging device, the lower surface of the main water pipe support frame is connected to the water droplet pipe type de-fogging device, and the two sides of the first water pipe support frame are embedded and installed in the interior of the first roof de-fogging device.

[0004] Manual wiping can achieve de-fogging, but the efficiency is low. Although the de-fogging state disclosed in the above patent can achieve de-fogging to a certain extent, the cost is high, especially in some special cases, the de-fogging device is damaged or cannot completely remove the water mist or frost on the glass due to the weather, which can also affect the driver's visual field to a certain extent. Therefore, how to maximize the driver's visual field in the bridge is the basis for safe driving, and the existing technology cannot reliably transmit the visual field to the driver due to the fog produced by the glass or the de-fogging effect caused by the fog on the glass, which affects the safety of the ship.

BRIEF DESCRIPTION OF DRAWINGS
[0016] The content expressed by each drawing of the present application and the marks in the drawings are briefly described as follows:
[0017] Figure 1 It is a structure principle diagram of the control system of the utility model. DETAILED DESCRIPTION
[0018] The specific embodiments of the present application are further described in detail by comparing the drawings and describing the optimal embodiments.
[0019] The embodiment mainly solves the problem of the field of view obstruction of the driver in the cab through the intelligent control system of the ship cab; since the field of view in the cab generally views the front obstacles of the proceeding direction through the front windshield, but due to the environment of the ship navigation, the front windshield may be fogged to cause the front view to be unclear, therefore, in order to avoid the influence on the field of view in the cab or reduce the influence on the field of view, the present scheme adopts two ways to process: way 1: defogging, reducing the fogging of the front windshield to cause the front view to be unclear; way 2: automatically opening the digital camera, in the case that the defogging cannot be completed or the defogging effect is poor, the front picture collected through the camera can be used to solve the problem of the field of view. The specific scheme is as follows:
[0020] As shown in Figure 1 A ship cab intelligent control system, comprising a control unit, resistance wires arranged on a front windshield of the cab, and an NTC temperature sensor; wherein the control unit is used as a core controller, which is realized by using an embedded controller DSP or a single-chip microcomputer development board, and the core control function of the present application is realized by using a DSP controller or a single-chip microcomputer.
[0021] The number of the resistance wires is multiple, which are distributed on the front windshield, and the resistance wires play a heating role and can heat the front windshield in the cockpit after being electrified, and the setting position is attached to the inner side of the front windshield, in order to reduce the influence of the resistance wires on the field of view on the glass, the setting position can be considered and can be dispersedly arranged around the front windshield, so that the driver can view the front water surface condition through the middle position, and the specific arrangement can be set according to actual requirements.
[0022] The NTC temperature sensor is used to collect the glass temperature and the temperature outside the cab, and the output thereof is connected to the control unit; the NTC temperature sensor is a conventional temperature sensor which is used to convert the temperature value according to the resistance value change, and the NTC temperature sensor can be at least two, which are arranged on the glass outside and inside the cab respectively, so as to collect the inside and outside temperature data, and then the inside and outside temperature difference data can be calculated according to the inside and outside temperature data, because the inside and outside temperature difference is the condition of the glass fogging, so the working state of the resistance wire is controlled according to the collected inside and outside temperature difference, and the control unit controls the working state of each resistance wire according to the temperature difference between the collected glass temperature and the temperature outside the cab; when the temperature difference is greater than the set threshold, the resistance wire is started to work, and when the temperature difference is less than the set threshold, the working of the resistance wire is turned off; in the control process, the resistance wire is controlled through the electronic switch, and the like, because the resistance wire only needs to be powered to work, and the electronic switch is arranged in series in the power supply circuit of the resistance wire, so that the working of the resistance wire is controlled.
[0023] A digital camera is arranged at the head of the ship, that is, the control system further comprises a digital camera, the digital camera is arranged at the head of the ship, the digital camera is used to collect the video signal of the ship running direction, the digital camera is connected to the monitoring large screen through the LVDS interface circuit, and the monitoring large screen is arranged in the cab; the output of the control unit is connected to the monitoring large screen to start the monitoring large screen. The digital camera adopts a conventional camera to collect the video data in front of the ship running direction, and is connected to the monitoring large screen through the LVDS interface circuit, so that the video picture in front of the ship running direction can be displayed as long as the monitoring large screen is started, so that the digital conversion of the front view is realized, and the view is convenient to check. The working linkage defogging function is that when the control unit judges whether to start the resistance wire according to the temperature difference, the monitoring large screen is started through the temperature difference linkage control, that is, when the temperature difference is greater than the set threshold, the working of the resistance wire is started, and the working of the monitoring large screen is started at the same time, so that the resistance wire reduces the fogging of the front windshield glass through heating to realize the defogging function, improves the front view, and displays the video picture in front of the running through the monitoring large screen, so that the driver can check conveniently, and the purpose of double guarantee of the view is realized. Even if the defogging effect is not good or the defogging is not timely, the view of the driver is not affected. Even if the glass has fog and affects the view, the image collected by the camera can provide a relatively clear view through the display mode of the monitoring large screen in the cab, so that the view guarantee of the ship is realized.
[0024] In a preferred embodiment, the control unit is connected with a manual switch, and the operation of the resistance wire is controlled by the manual switch. The manual switch can be a button, a key, a knob or the like, and the control unit is triggered by the button to actively open and close the resistance wire. In some cases, the automatic opening by temperature difference detection cannot meet the requirements of defogging opening, and the manual opening function is provided for easy opening. The control unit controls the opening of the monitoring large screen at the same time of manually opening the resistance wire.
[0025] In order to avoid the out-of-control operation of the resistance wire, the control unit is connected with a power regulation module in the scheme, and the power regulation module is arranged in series in the loop between each resistance wire and its power supply. The working current / voltage of each resistance wire is adjusted by the power regulation module, so as to avoid the risk of glass overheating caused by resistance wire overheating, and the working current of the resistance wire is limited in a set range. At the same time, the working of the power regulation module can be controlled according to the glass temperature collected by the NTC thermistor temperature sensor.
[0026] In the embodiment, in order to improve the accuracy of the control unit in judging the possibility of fogging, an air humidity sensor is arranged in the cab. The air humidity sensor is used to detect the air humidity in the cab, and its output end is connected to the control unit. The judgment of the possibility of fogging by temperature difference alone can realize the judgment of fogging in most cases, but the fogging condition not only contains temperature difference, but also contains air humidity. Therefore, in a preferred scheme, the control unit judges whether there is a risk of fogging according to the two parameters of temperature difference and air humidity, and controls the working of the resistance wire according to the judgment result, so as to realize the accurate function of automatic opening of the defogging function.
[0027] In another preferred embodiment of the application, a rain sensor is arranged outside the ship's bridge, and the arrangement position includes the top of the ship and the like, which is used to monitor whether the current weather is in the state of raining, and its output end is connected to the control unit. The control unit controls the start of the monitoring large screen according to the raining state. Since the visibility in the cab is also affected when it rains, in order to solve the limitation of the visibility when it rains, the monitoring large screen is also automatically opened in the scheme, so as to provide a double checking way for the visibility of the driver in the cab, and ensure the visibility of the driver in the cab.
[0028] In the scheme, the power supply of the control system is realized by the shipboard power supply or the newly added storage battery, and the stable 24V DC power supply is provided by the power supply module to supply power to the resistance wire and the controller. Through the cooperative work of the distributed resistance wire, the NTC temperature sensor, the power supply and the controller, the efficient defogging, temperature control and energy-saving operation of the window are realized to realize the guarantee of the visibility in the bridge.
[0029] The arrangement of the resistance wires is set based on the view of the driver through the glass, and can be arranged on the surface of the inner side of the window glass, and is arranged in a grid or parallel line shape in a uniform distribution to ensure uniform heating of the entire surface, and is set based on the view of the glass. During the heating process, the NTC sensor continuously responds to temperature changes and provides real-time feedback of the current temperature through changes in resistance. The controller dynamically adjusts the heating power of the resistance wires according to the temperature changes. For example, when the glass temperature approaches the target value or the temperature difference is less than the set threshold, the controller maintains a constant temperature by reducing the current or intermittently supplying power to avoid overheating. When the circuit current exceeds the safe range or the temperature exceeds the limit, the system reduces the heating power or directly disconnects the circuit to prevent system damage or glass overheating. When the surface temperature of the glass reaches the target value (usually slightly higher than the indoor temperature) and the fog is completely eliminated, the controller cuts off the heating circuit, and the system enters a low-power standby state, which can be controlled manually or automatically.
[0030] The embodiment also provides a ship comprising the intelligent control system in the above embodiment, and since the ship has all the features of the intelligent control system, it also has the technical advantages thereof: for improving the view of the driver in the driver's cabin, reducing the influence of fog and the like on the view of the driver, and through the simple and low-cost line-of-sight defogging of the designed defogging system, and in order to reduce the view obstruction caused by poor defogging effect or other reasons, a linkage digital camera is additionally arranged to collect image pictures, so as to reduce the influence of the view obstruction on the safety of the ship as much as possible.
[0031] Obviously, the specific implementation of the present application is not limited to the above-mentioned manner, and various non-essential improvements made by adopting the method concept and technical solution of the present application are within the protection scope of the present application.
