[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In the current common aircraft take-off mode, the aircraft's refueling volume is usually limited based on factors such as the aircraft's flight characteristics, airport runway length, and cargo loading capacity, and does not need to be confirmed and reviewed before take-off. However, in short-distance taxi take-off or special take-off modes, the aircraft's refueling volume and take-off weight need to be confirmed and reviewed before take-off. In this case, ground staff need a weight display board such as the utility model to quickly and accurately complete the take-off weight review work.

[0029] (I) System composition

[0030] The utility model mainly includes a power supply unit, a digital display module, a power switch, a dimming knob and a key unit. The power supply unit includes a battery and a charging adapter; the digital display module is composed of a 9-digit digital tube; the key unit is composed of 8 pairs of "+", "-" keys and "lock", "unlock" and "reset" keys.

[0031] 1. Power supply unit

[0032] In order to achieve the portability of the display panel, the display panel is powered by a battery, and the power supply unit consists of a charging adapter, a charging splitter, and a battery.

[0033] The display panel system uses a battery pack to output 12VDC for power supply. Considering the equipment's power storage capacity, appearance size, weight and other factors, the battery capacity is 90Wh, which has the characteristics of reliable quality, high energy density and high safety. Through the design of the single-chip computer and control circuit, the power consumption calculation analysis of the digital LED module and the actual verification of similar projects, it can be fully charged within 1 hour. When fully charged, it can work and display continuously for 12 to 18 hours when powered by the battery alone. Secondly, in order to extend the continuous use time of a single display panel, the battery is designed to be replaceable.

[0034] 2. Digital display module

[0035] The display board displays the required onboard weight of the staff in 9 digits, and 7 of the displayed digits are designed to be adjustable. The adjustable digital LED module with RS485 communication is selected. By sending RS485 instructions to the adjustable digital LED module, the display shift output chip inside the display module is controlled to realize the numerical display of the display board. The brightness of the module can be set, and the current display brightness can be adjusted by the dimming knob outside the display board.

[0036] In order to present the numbers intuitively, the 9-digit number is designed as a double-layer digital display according to the aircraft's takeoff fuel volume and total weight (empty weight + loading / mounting + takeoff fuel volume). The upper layer displays 4 digits in the form of "x / y / z / 0" from left to right. The first three digits "x / y / z" are adjustable, and the last digit is fixed to "0". This layer of data is used to display the aircraft's takeoff fuel volume; the lower layer displays 5 digits in the form of "a / b / c / d / 0" from left to right. The first four digits "a / b / c / d" are adjustable and have accumulation and carry calculation functions. The last digit is fixed to "0". This layer of data is used to display the total weight (empty weight + loading / mounting + takeoff fuel volume). The digital display is as follows: Figure 1 shown.

[0037] The design of accumulation and carry function is mainly to complete the final display of total weight, and total weight is the sum of all weights (empty weight + loading / mounting + takeoff fuel). The adjustable digital LED module in the display panel can accumulate the numbers according to the corresponding digits through the designed "+" and "-" buttons. When the accumulated numbers of a single digital LED module exceed the number "9", it will automatically carry forward through internal program control. In the second-layer display digital design, the design can automatically accumulate the first-layer data. When the first-layer data is entered, the second layer will make a corresponding accumulation calculation of the current display data and the first-layer data. Enter one bit, accumulate one bit, and automatically carry when the number exceeds "9". (Note: The second-layer digits accumulate and calculate the total amount. The first-layer input numbers will not change with the accumulation of the second-layer numbers, and will be displayed according to the input numbers.)

[0038] In order to ensure that the digital display module is still clearly visible when observed from a distance, a 9-bit ultra-large adjustable digital LED module is selected. The size of a single digital display is 140mm×105mm×15mm, and a dimming function is designed so that the display can adjust the brightness according to the use environment during the day or at night, allowing users to clearly see the display content 10 meters away from the display board. The power consumption of a single digital LED module is 66mW, the brightness can be set, and the software and hardware dual watchdogs ensure that there will be no downtime. The package size of the digital tube is a standard size, and it is easy to buy the device on the market, which is convenient for maintenance and replacement. Its appearance is as follows Figure 2 shown.

[0039] 3. Button unit

[0040] It is composed of a microcontroller, a key acquisition circuit and keys. The microcontroller realizes the acquisition and conversion of the entire system. The display board processes the key values ​​collected by the microcontroller to realize operations such as carry, accumulation, locking, unlocking, and resetting of the displayed values. The key acquisition circuit is composed of multiple optocoupler acquisition circuits. When the user presses the corresponding key, the optocoupler circuit outputs different coding values ​​to the microcontroller. The microcontroller sends corresponding instructions to the digital display module in response to different codes, so that the digital display module displays the corresponding values, thereby realizing the change of the displayed values.

[0041] Take the acquisition unit of one pair of buttons as an example, the schematic diagram is as follows Figure 3 As shown. Connect the end of the push button switch to the acquisition unit. When the push button switch on the device is pressed, the corresponding circuit will be powered on. After the signal is isolated by the optical coupler, it is input to the microcontroller for measuring the switch signal. There are 17 switch signal acquisition channels in total, of which 14 channels are used to set the "+" and "-" values, and 3 channels are used for "lock", "unlock" and "reset" operations respectively.

[0042] There are corresponding buttons on the top, bottom, left and right sides of the display panel. The top side has 3 pairs of "+" and "-" buttons, which change the first 3 digits of the first line respectively; the bottom side has 4 pairs of "+" and "-" buttons, which change the first 4 digits of the second line respectively; on the right side there is a "-" button for changing the second digit of the first line, and a "reset" button; on the left side there is a "+" button for changing the second digit of the first line, and "lock" and "unlock" buttons. Buttons such as Figure 5-7 shown.

[0043] (II) Structural design

[0044] The main body of the display panel is designed with composite materials, the panel is made of organic high-transparency Mobi, and the panels are bonded with high-viscosity, high-strength silicone rubber, which has a certain degree of explosion-proof.

[0045] ≤580mm×340mm×20mm, weight ≤10kg. The whole device adopts a fully sealed design, and the waterproof and dustproof level of the whole device reaches IP55 level.
