In the present embodiment, the first relay 21 and the second relay 22 are switching relays.

切換裝置100的工作原理如下：The working principle of the switching device 100 is as follows:

當用戶在串口選擇區域211中選擇檢測串口S3時，電子設備200輸出第二訊號為低電平的選擇訊號。因此，第二引腳P2為低電平，使得第一線圈Z1通電，第一動觸點Z11與第一靜觸點Z12斷開，與第二靜觸點Z13閉合。此時，第三引腳P3與檢測串口S3的數據傳輸引腳Pa電性連接，即檢測設備T3的檢測數據被傳送到電子設備200並顯示於數據顯示區域212中。在本實施方式中，第一訊號可以為高電平也可以為低電平。When the user selects the detection serial port S3 in the serial port selection area 211, the electronic device 200 outputs a selection signal whose second signal is a low level. Therefore, the second pin P2 is at a low level, so that the first coil Z1 is energized, the first movable contact Z11 is disconnected from the first stationary contact Z12, and the second stationary contact Z13 is closed. At this time, the third pin P3 is electrically connected to the data transmission pin Pa of the detection serial port S3, that is, the detection data of the detecting device T3 is transmitted to the electronic device 200 and displayed in the data display area 212. In this embodiment, the first signal may be a high level or a low level.

當用戶在串口選擇區域211中選擇檢測串口S2時，電子設備200輸出第一訊號為低電平，第二訊號為高電平的選擇訊號。因此，第一引腳P1為低電平，第二引腳P2為高電平。使得第一線圈Z1不通電，第二線圈Z2通電；進而使得第一動觸點Z11與第一靜觸點Z12閉合，與第二靜觸點Z13斷開；第二動觸點Z21與第三靜觸點Z22斷開，與第四靜觸點Z23閉合。此時，第三引腳P3與檢測串口S2的數據傳輸引腳Pa電性連接，即檢測設備T2的檢測數據被傳送到電子設備200並顯示於數據顯示區域212中。When the user selects the detection serial port S2 in the serial port selection area 211, the electronic device 200 outputs a selection signal in which the first signal is a low level and the second signal is a high level. Therefore, the first pin P1 is at a low level, and the second pin P2 is at a high level. The first coil Z1 is not energized, and the second coil Z2 is energized; thereby, the first movable contact Z11 and the first stationary contact Z12 are closed, and the second stationary contact Z13 is disconnected; the second movable contact Z21 and the third The stationary contact Z22 is open and closed with the fourth stationary contact Z23. At this time, the third pin P3 is electrically connected to the data transmission pin Pa of the detection serial port S2, that is, the detection data of the detecting device T2 is transmitted to the electronic device 200 and displayed in the data display area 212.

當用戶在串口選擇區域211中選擇檢測串口S1時，電子設備200輸出第一訊號為高電平，第二訊號也為高電平的選擇訊號。因此，第一引腳P1與第二引腳P2均為高電平。使得第一線圈Z1與第二線圈Z2同時不通電，進而使得第一動觸點Z11與第一靜觸點Z12閉合，與第二靜觸點Z13斷開；第二動觸點Z21與第三靜觸點Z22閉合，與第四靜觸點Z23斷開。此時，第三引腳P3與檢測串口S1的數據傳輸引腳Pa電性連接，即檢測設備T1的檢測數據被傳送到電子設備200並顯示於數據顯示區域212中。When the user selects the detection serial port S1 in the serial port selection area 211, the electronic device 200 outputs a selection signal in which the first signal is a high level and the second signal is also a high level. Therefore, the first pin P1 and the second pin P2 are both at a high level. The first coil Z1 and the second coil Z2 are not energized at the same time, so that the first movable contact Z11 and the first stationary contact Z12 are closed, and the second stationary contact Z13 is disconnected; the second movable contact Z21 and the third The stationary contact Z22 is closed and disconnected from the fourth stationary contact Z23. At this time, the third pin P3 is electrically connected to the data transmission pin Pa of the detection serial port S1, that is, the detection data of the detecting device T1 is transmitted to the electronic device 200 and displayed in the data display area 212.

如此，只要在串口選擇區域211中選擇目標檢測設備Ta，電子設備200就會輸出相應的選擇訊號，進而將目標檢測設備Ta的檢測數據傳送給電子設備200並顯示於數據顯示區域212中，從而避免了習知技術中需要手動將每一台目標檢測設備Ta與電子設備200進行連接的操作，節省了時間，提高了檢測效率。In this manner, if the target detection device Ta is selected in the serial port selection area 211, the electronic device 200 outputs a corresponding selection signal, and then transmits the detection data of the target detection device Ta to the electronic device 200 and displays it in the data display area 212, thereby The operation of manually connecting each of the target detecting devices Ta and the electronic device 200 is avoided in the prior art, which saves time and improves the detection efficiency.
