Description
本發明涉及一種監視模組,特別是關於一種固態繼電器的監視模組及具有監視模組的加熱爐裝置。 The present invention relates to a monitoring module, in particular to a monitoring module of a solid state relay and a heating furnace device having the monitoring module.
固態繼電器(Solid State Relay,SSR)具有無火花、無雜訊、開關速度快等特點,不像傳統電磁繼電器在快速ON/OFF週期時有容易損壞的問題,已逐漸取代傳統電磁繼電器。固態繼電器具有輸入端與輸出端,輸入端與輸出端中間以光隔離元件隔離,並在信號由輸入端輸入之後,使輸出端從開路(斷路)轉變成短路(通路)狀態,進而導通高功率之輸出電流,但有時會因負載電流過大或溫度過高而故障,使得固態繼電器的輸出端一直保持短路或開路,而無法關斷或接通。 Solid State Relay (SSR) has the characteristics of no spark, no noise, fast switching speed, etc. Unlike traditional electromagnetic relays, which are easily damaged during fast ON/OFF cycles, it has gradually replaced traditional electromagnetic relays. Solid-state relays have input and output ends, which are isolated by optical isolation elements. After the signal is input from the input end, the output end changes from open circuit (broken circuit) to short circuit (passed) state, thereby conducting high-power output current. However, sometimes it will fail due to excessive load current or high temperature, causing the output end of the solid-state relay to remain short-circuited or open-circuited, and cannot be turned off or turned on.
申請人曾提出一種「固態繼電器的監視模組及具有該監視模組的加熱爐」(TW I632581),該固態繼電器設於控制器與負載之間,該監視模組包含一輸入端信號偵測單元、一輸出端電流偵測單元、一警示輸出單元、及處理單元,可透過輸入端信號偵測單元偵測控制器輸入至固態繼電器輸入端的控制信號,並對應產生一信號偵測結果,又透過輸出端電流偵測單元偵測固態繼電器的輸出端的電流,並對應產生一電流偵測結果,使處理單元能根據接收的信號偵測結果及電流偵測結果即時判斷固態繼電器的故障,並能 在固態繼電器故障時立即通報。 The applicant once proposed a "monitoring module of a solid-state relay and a heating furnace with the monitoring module" (TW I632581).

[實施例的有益效果] [Beneficial effects of the embodiment]
本發明的有益效果在於,本發明所提供的固態繼電器的監視模組及具有監視模組的加熱爐裝置,本發明可透過固態繼電器溫度偵測單元的第一偵測器及第二偵測器偵測固態繼電器的輸出端溫度,並透過固態繼電器溫度偵測單元的第三偵測器偵測固態繼電器溫度,第一偵測器、第二偵測器及第三偵測器偵測溫度,並對應產生一溫度偵測結果,使處理單元能根據接收的溫度偵測結果即時判斷固態繼電器、輸出端是否過熱,並能在固態繼電器、輸出端過熱時立即通報。 The beneficial effect of the present invention is that the solid-state relay monitoring module and the heating furnace device with the monitoring module provided by the present invention can be used through the first detector and the second detector of the solid-state relay temperature detection unit. Detect the temperature of the output end of the solid-state relay, and detect the temperature of the solid-state relay through the third detector of the solid-state relay temperature detection unit. The first detector, the second detector and the third detector detect the temperature, And correspondingly generates a temperature detection result, so that the processing unit can instantly determine whether the solid-state relay and the output terminal are overheated based on the received temperature detection result, and can immediately report when the solid-state relay and the output terminal are overheated.
再者,監視模組連接於控制器及固態繼電器的輸入端之間,因固態繼電器輸入控制信號,是由監視模組發出,所以只要有任何警報,均可立即切斷固態繼電器的控制信號,使其不動作,保護更完整。 Furthermore, the monitoring module is connected between the controller and the input terminal of the solid-state relay. Since the input control signal of the solid-state relay is sent by the monitoring module, as long as there is any alarm, the control signal of the solid-state relay can be cut off immediately. Make it inactive and the protection is more complete.
