Description

自動除濕控制裝置Automatic dehumidification control device

本發明是有關於一種裝置，特別是指一種用於發光二極體顯示螢幕的自動除濕控制裝置。The present invention relates to a device, in particular to an automatic dehumidification control device for a light-emitting diode display screen.

現有發光二極體（Light Emitting Diode，LED）顯示螢幕係由數量龐大的LED所組裝而成，每一LED可對抗之溫度、濕度、環境變化均不相同，為了避免該LED顯示螢幕於開機過程中因LED內部存在濕氣而短路，因此在開啟已關閉一段時間之該LED顯示螢幕時，會先透過一外部發射器內的一控制單元於一預設緩啟動時間產生一亮度控制信號來將每一LED的亮度調低（即，一預設緩啟動操作），並於該預設緩啟動時間結束後才將每一LED的亮度逐漸調高至一初始預設亮度，以排除每一LED內部的濕氣，進而保護該LED顯示螢幕的壽命。Existing Light Emitting Diode (LED) display screens are assembled from a large number of LEDs, and each LED can resist temperature, humidity, and environmental changes differently. In order to avoid the LED display screen during the boot process Due to the existence of moisture inside the LED, there is a short circuit, so when the LED display screen that has been turned off for a period of time is turned on, a control unit in an external transmitter will first generate a brightness control signal at a preset slow start time to Turn down the brightness of each LED (ie, a preset slow-start operation), and gradually increase the brightness of each LED to an initial preset brightness after the preset slow-start time expires to exclude each LED moisture inside, which in turn protects the life of the LED display screen.

然而，在上述除濕方法中，由於該預設緩啟動時間為一固定值，該預設緩啟動時間不會隨該LED顯示螢幕關閉時間的長短而改變，因此在某些情況下，例如該LED顯示螢幕關閉時間過長，造成該預設緩啟動時間不足以排除每一LED內部濕氣，如此將縮短該等LED壽命或使該等LED因濕氣短路而燒毀。此外，若遇到瞬間跳電且該LED顯示螢幕短時間重啟時，該控制單元仍會對每一LED重新執行該預設緩啟動操作，在此期間，將導致該LED顯示螢幕亮度無法達到該初始預設亮度，影響使用者的視覺效果。However, in the above dehumidification method, since the preset slow start time is a fixed value, the preset slow start time will not change with the length of time the LED display screen is turned off. Therefore, in some cases, for example, the LED If the display screen is turned off for too long, the preset slow start time is not enough to remove the moisture inside each LED, which will shorten the life of the LEDs or cause the LEDs to be burnt due to short circuit of moisture. In addition, if there is a momentary power outage and the LED display screen is restarted for a short time, the control unit will still re-execute the preset slow start operation for each LED, during this period, the brightness of the LED display screen will not reach the required level. The initial preset brightness affects the user's visual effect.

因此，本發明的目的，即在提供一種能夠克服先前技術缺點的自動除濕控制裝置。Therefore, the purpose of the present invention is to provide an automatic dehumidification control device which can overcome the disadvantages of the prior art.

參閱表1，其列出該查找表的一實施態樣，但不限於此。Please refer to Table 1, which lists an implementation aspect of the lookup table, but is not limited thereto.

表1：      預設緩啟動         時間(hr) 預設時間 差範圍(days) 2~4hr 4~6hr 6~8hr 8~10hr 10~12hr 12~14hr Cr＜1 初始預設亮度 2＜Cr＜3 25% 50% 100% 初始預設亮度 4＜Cr＜5 10% 25% 50% 75% 100% 初始預設亮度 Table 1: Preset slow start time (hr) Preset time difference range (days) 2~4hr 4~6hr 6~8hr 8~10hr 10~12hr 12~14hr Cr<1 Initial preset brightness 2<Cr<3 25% 50% 100% Initial preset brightness 4<Cr<5 10% 25% 50% 75% 100% Initial preset brightness

舉例來說，表1之初始預設亮度為使用者原本對該LED顯示螢幕2的亮度所設定的預設值。當該比較結果Cr所指示之時間差小於一天時（即，表1之Cr＜1，對應該LED顯示螢幕2關閉時間在1天內），該LED顯示螢幕2無須進行除濕且直接根據該初始預設亮度發光，因此，該緩啟動控制器171根據該比較結果Cr及該查找表所產生的該緩啟動控制信號Sc中，該預設緩啟動時間為零，且其所對應的LED亮度變化為該初始預設亮度。當該比較結果Cr所指示之時間差大於二天且小於三天時（即，表1之2＜Cr＜3，對應該LED顯示螢幕2已經關閉2~3天內），開啟該發射器10及該LED顯示螢幕2時，初始的該LED顯示螢幕2在開啟的2~4小時間的亮度僅有總亮度的25%，在開啟的4~6小時間的亮度會提升至總亮度的50%，在開啟的6~8小時間的亮度會提升至總亮度（即，100%）。當開機超過8小時後，該LED顯示螢幕2亮度會回歸至該初始預設亮度。因此，該緩啟動控制器171根據該比較結果Cr及該查找表所產生的該緩啟動控制信號Sc中，該預設緩啟動時間為8小時，且其所對應的LED亮度變化分別為2~4小時間為總亮度的25%、4~6小時間為總亮度的50%、6~8小時間為總亮度的100%、超過8小時後為該始預設亮度。For example, the initial preset brightness in Table 1 is the default value originally set by the user for the brightness of the LED display screen 2 . When the time difference indicated by the comparison result Cr is less than one day (that is, Cr<1 in Table 1, corresponding to the closing time of the LED display screen 2 within 1 day), the LED display screen 2 does not need to be dehumidified and directly Set the brightness to emit light, therefore, in the slow-start control signal Sc generated by the slow-start controller 171 according to the comparison result Cr and the look-up table, the preset slow-start time is zero, and the corresponding LED brightness change is The initial preset brightness. When the time difference indicated by the comparison result Cr is greater than two days and less than three days (that is, 2<Cr<3 in Table 1, corresponding to the LED display screen 2 has been turned off within 2~3 days), turn on the transmitter 10 and the When the LED display screen 2, the initial brightness of the LED display screen 2 is only 25% of the total brightness during the 2~4 hours of opening, and the brightness will increase to 50% of the total brightness during the 4~6 hours of opening. The brightness will be boosted to the full brightness (ie, 100%) during the 6~8 hours of turning on. When the power is turned on for more than 8 hours, the brightness of the LED display screen 2 will return to the initial preset brightness. Therefore, in the slow-start control signal Sc generated by the slow-start controller 171 according to the comparison result Cr and the look-up table, the preset slow-start time is 8 hours, and the corresponding LED brightness changes are respectively 2~ 4 hours is 25% of the total brightness, 4~6 hours is 50% of the total brightness, 6~8 hours is 100% of the total brightness, and the default brightness is the default after more than 8 hours.

該畫面控制器172產生該時間同步信號St並輸出至該時間計數單元14之該時間取得器141，且電連接該緩啟動控制器171及該LED顯示螢幕3。該畫面控制器172接收來自該緩啟動控制器171的該緩啟動控制信號Sc，並根據該緩啟動控制信號Sc產生該亮度控制信號Lc，且將該亮度控制信號Lc輸出至該LED顯示螢幕3，以調整該LED顯示螢幕3的亮度以進行除濕。The screen controller 172 generates the time synchronization signal St and outputs it to the time acquirer 141 of the time counting unit 14 , and is electrically connected to the slow start controller 171 and the LED display screen 3 . The screen controller 172 receives the slow-start control signal Sc from the slow-start controller 171 , generates the brightness control signal Lc according to the slow-start control signal Sc, and outputs the brightness control signal Lc to the LED display screen 3 , to adjust the brightness of the LED display screen 3 for dehumidification.

舉例來說，參上表1，當該比較結果Cr所指示之時間差小於一天時，該畫面控制器172所產生的該亮度控制信號Lc控制該LED顯示螢幕3無須進行除濕（即，無須進行一預設緩啟動操作）且直接根據該初始預設亮度發光。當該比較結果Cr所指示之時間差大於二天且小於三天時，該畫面控制器172所產生的該亮度控制信號Lc控制該LED顯示螢幕3於該預設緩啟動時間8小時內進行除濕，且控制該LED顯示螢幕3於開機2~4小時間的亮度為總亮度的25%、於開機4~6小時間的亮度為總亮度的50%、於開機6~8小時間的亮度為總亮度的100%、於開機超過8小時後直接根據該初始預設亮度發光。當該比較結果Cr所指示之時間差大於四天且小於五天時，該畫面控制器172所產生的該亮度控制信號Lc控制該LED顯示螢幕3於該預設緩啟動時間12小時內進行除濕，且控制該LED顯示螢幕3於開機2~4小時間的亮度為總亮度的10%、於開機4~6小時間的亮度為總亮度的25%、於開機6~8小時間的亮度為總亮度的50%、於開機8~10小時間的亮度為總亮度的75%、於開機10~12小時間的亮度為總亮度的100%、於開機超過12小時後直接根據該初始預設亮度發光。For example, referring to Table 1 above, when the time difference indicated by the comparison result Cr is less than one day, the brightness control signal Lc generated by the image controller 172 controls the LED display screen 3 without dehumidification (ie, without a Preset slow start operation) and emit light directly according to the initial preset brightness. When the time difference indicated by the comparison result Cr is greater than two days and less than three days, the brightness control signal Lc generated by the image controller 172 controls the LED display screen 3 to dehumidify within the preset slow start time of 8 hours, and Control the brightness of the LED display screen 3 to be 25% of the total brightness during 2~4 hours of power on, 50% of the total brightness during 4~6 hours of power on, and 50% of the total brightness during 6~8 hours of power on 100% of the light, and it will emit light directly according to the initial preset brightness after more than 8 hours of power on. When the time difference indicated by the comparison result Cr is greater than four days and less than five days, the brightness control signal Lc generated by the image controller 172 controls the LED display screen 3 to dehumidify within the preset slow start time of 12 hours, And control the brightness of the LED display screen 3 to be 10% of the total brightness during 2-4 hours of power-on, 25% of the total brightness during 4-6 hours of power-on, and 25% of the total brightness during 6-8 hours of power-on. 50% of the brightness, 75% of the total brightness when powered on for 8~10 hours, 100% of the total brightness when powered on for 10~12 hours, and directly based on the initial preset brightness after more than 12 hours of power on glow.

需補充說明的是，當一設有一發射器控制軟體的外部電腦（圖未示）經由一通用序列匯流排（Universal Serial Bus，USB）電連接至該畫面控制器172，且使用者開啟該發射器控制軟體時，該外部電腦即將該時間同步信號St經由該通用序列匯流排及該畫面控制器172傳輸至該時間取得器141，以進行時間同步更新。此外，該發射器控制軟體的介面具有一個啟動該自動除濕控制裝置1的除濕模式選項，當該除濕模式選項被點選後，該自動除濕控制裝置1即被致能。在本實施例中，該外部電腦並非一直電連接該發射器10，而是須對該發射器10進行參數設定或時間同步時，使用者才將該外部電腦電連接至該發射器10。使用者在利用該外部電腦之該發射器控制軟體對該發射器10進行初始參數設定時，即一併點選該除濕模式選項並致能該自動除濕控制裝置1。It should be added that when an external computer (not shown) provided with a transmitter control software is electrically connected to the screen controller 172 via a Universal Serial Bus (USB), and the user turns on the transmitter When the controller control software is used, the external computer transmits the time synchronization signal St to the time acquirer 141 via the universal serial bus and the screen controller 172 for time synchronization update. In addition, the interface of the transmitter control software has a dehumidification mode option for enabling the automatic dehumidification control device 1. When the dehumidification mode option is selected, the automatic dehumidification control device 1 is enabled. In this embodiment, the external computer is not always electrically connected to the transmitter 10 , but the user can electrically connect the external computer to the transmitter 10 only when the transmitter 10 needs to be parameterized or time synchronized. When the user uses the transmitter control software of the external computer to set the initial parameters of the transmitter 10 , he/she clicks the dehumidification mode option and enables the automatic dehumidification control device 1 .

以下舉本發明的一實施態樣做說明，但不限於此。詳細來說，該時間取得器141會先根據該時間同步信號St產生該同步時間Ts，且將該同步時間Ts輸出至該計時器142以進行計數。由於該電池單元15持續供電給該計時器142，因此該計時器142得以持續進行計數並產生該計數時間Tc（例如，該計時器142每隔一分鐘即產生該計數時間Tc）。接著，該計時器142將所產生的該計數時間Tc定期地（例如連續地）輸出至該時間取得器141，以致該時間取得器141根據該計數時間Tc對該同步時間Ts進行更新，以產生該第一時間T1。當該發射器電源供應單元2未開啟前，由於該自動除濕控制裝置1已於初始該發射器10進行參數設定階段時被致能，因此在該發射器電源供應單元2前一次斷電時，該電壓偵測單元13所偵測到的該電壓偵測信號Vd的準位為一低邏輯準位（即，該電壓偵測信號Vd的準位為「0」，該發射器電源供應單元2被關閉，且該發射器10及該LED顯示螢幕3關機），該時間取得器141根據該電壓偵測信號Vd將當時的該第一時間T1儲存至該第一記憶體121。An embodiment of the present invention is described below, but is not limited thereto. Specifically, the time obtainer 141 first generates the synchronization time Ts according to the time synchronization signal St, and outputs the synchronization time Ts to the timer 142 for counting. Since the battery unit 15 continues to supply power to the timer 142 , the timer 142 can continue to count and generate the count time Tc (eg, the timer 142 generates the count time Tc every one minute). Next, the timer 142 outputs the generated count time Tc to the time obtainer 141 periodically (eg, continuously), so that the time obtainer 141 updates the synchronization time Ts according to the count time Tc to generate the first time T1. When the transmitter power supply unit 2 is not turned on, since the automatic dehumidification control device 1 is enabled when the transmitter 10 is in the parameter setting stage, when the transmitter power supply unit 2 is powered off the previous time, The level of the voltage detection signal Vd detected by the voltage detection unit 13 is a low logic level (ie, the level of the voltage detection signal Vd is "0", the transmitter power supply unit 2 is turned off, and the transmitter 10 and the LED display screen 3 are turned off), the time acquirer 141 stores the current first time T1 in the first memory 121 according to the voltage detection signal Vd.

接著，當該發射器電源供應單元2被開啟時，該電壓偵測信號Vd的準位從原本的該低邏輯準位轉變為一高邏輯準位（即，該電壓偵測信號Vd的準位為「1」，且該發射器10及該LED顯示螢幕3開機）。該計時器142根據該電壓偵測信號Vd將當前計數的該計數時間Tc作為該第二時間T2，並將該第二時間T2儲存至該第二記憶體122。然後，該比較單元16將該等第一及第二時間T1、T2進行比較，以產生該比較結果Cr。該緩啟動控制器171根據該比較結果Cr及該查找表產生該緩啟動控制信號Sc。最後，該畫面控制器172根據該緩啟動控制信號Sc產生該亮度控制信號Lc來調整該LED顯示螢幕3，以緩慢改變該LED顯示螢幕3的亮度來消除該等LED內的濕氣，進而達到除濕效果。Then, when the transmitter power supply unit 2 is turned on, the level of the voltage detection signal Vd changes from the original low logic level to a high logic level (ie, the level of the voltage detection signal Vd is "1", and the transmitter 10 and the LED display screen 3 are powered on). The timer 142 uses the currently counted count time Tc as the second time T2 according to the voltage detection signal Vd, and stores the second time T2 in the second memory 122 . Then, the comparison unit 16 compares the first and second times T1, T2 to generate the comparison result Cr. The slow-start controller 171 generates the slow-start control signal Sc according to the comparison result Cr and the look-up table. Finally, the picture controller 172 generates the brightness control signal Lc according to the slow start control signal Sc to adjust the LED display screen 3 to slowly change the brightness of the LED display screen 3 to eliminate the moisture in the LEDs, thereby achieving Dehumidifying effect.

當該發射器電源供應單元2再次被關閉時，此時該電壓偵測信號Vd的準位從該高邏輯準位轉變為該低邏輯準位，該時間取得器141根據該電壓偵測信號Vd將此時的該第一時間T1儲存至該第一記憶體121。當該發射器電源供應單元2再次被開啟時，該計時器142根據該電壓偵測信號Vd將當前計數的該計數時間Tc作為該第二時間T2並儲存至該第二記憶體122。重複執行上述比較及輸出另一個亮度控制信號Lc。When the transmitter power supply unit 2 is turned off again, the level of the voltage detection signal Vd is changed from the high logic level to the low logic level, and the time obtainer 141 is based on the voltage detection signal Vd The first time T1 at this time is stored in the first memory 121 . When the transmitter power supply unit 2 is turned on again, the timer 142 stores the counted time Tc currently counted as the second time T2 in the second memory 122 according to the voltage detection signal Vd. The above comparison is repeatedly performed and another luminance control signal Lc is output.

綜上所述，本發明該自動除濕控制裝置1是根據該發射器電源供應單元2的關閉與開啟間的時間差（即，對應該發射器10與該LED顯示螢幕3的關機時間長短）自動對該LED顯示螢幕3進行除濕控制，且該緩啟動控制信號Sc中的該預設緩啟動時間會隨該比較結果Cr的改變而變化，其並非如現有技術的預設緩啟動時間為一固定值，如此一來，當該發射器電源供應單元2的關閉時間過長時，該預設緩啟動時間也會對應增加，進而有足夠的緩啟動時間可供該LED顯示螢幕3排除每一LED內部濕氣，避免縮短該等LED壽命或使該等LED因濕氣短路而燒毀。此外，若遇到瞬間跳電且該發射器電源供應單元2短時間重啟時，由於該比較結果Cr所指示之時間差小於一最低預設時間差（在表1中，該最低預設時間差為一天，但不限於此），該畫面控制器172所產生的該亮度控制信號Lc控制該LED顯示螢幕3無須進行除濕且直接根據該初始預設亮度發光，進而可避免影響使用者的視覺效果。To sum up, the automatic dehumidification control device 1 of the present invention automatically adjusts the power supply unit 2 according to the time difference between turning off and turning on the transmitter power supply unit 2 (ie, corresponding to the length of the off time of the transmitter 10 and the LED display screen 3). The LED display screen 3 performs dehumidification control, and the preset slow-start time in the slow-start control signal Sc changes with the comparison result Cr, which is not a fixed value as in the prior art. In this way, when the power supply unit 2 of the transmitter is turned off for a long time, the preset slow start time will also increase accordingly, so that there is enough slow start time for the LED display screen 3 to exclude the interior of each LED Moisture, to avoid shortening the life of the LEDs or causing the LEDs to burn out due to short-circuiting by moisture. In addition, if there is an instantaneous power outage and the transmitter power supply unit 2 is restarted for a short time, since the time difference indicated by the comparison result Cr is less than a minimum preset time difference (in Table 1, the minimum preset time difference is one day, But not limited to this), the brightness control signal Lc generated by the image controller 172 controls the LED display screen 3 without dehumidification and directly emits light according to the initial preset brightness, thereby avoiding affecting the user's visual effect.
