Description of the invention (1) The present invention relates to a server fault detection system and method, and particularly to a system and method for detecting and recovering a server fault by automatically recovering the faulty server. In recent years, due to the vigorous development of the network, the system management work (M IS) of the overall network system has become increasingly important. At the same time, how to maintain and provide a stable and normal server (Ser v er) at any time and place Working conditions have also become an important issue. In addition, due to the formation of the concept of a global village, long-distance, multinational services, and information services anytime and anywhere have become common work patterns. And in the middle of the night or in the absence of system administrators, if the server temporarily fails, such as improper user operation or system software, etc., the server must be waited for when the server fails. Network management personnel perform troubleshooting and other processing, which in turn causes server service interruption and affects the overall service quality of the system. However, in many cases, the server crash is caused by the detailed design problems of the system software itself, or the user's improper access to the server, and the server can be recovered only by shutting down / booting the server again. Normal service. Therefore, in such a situation that the server can be resolved by simply restarting the server, how to shorten the time from the server crashing to restarting has become another important issue. In view of this, the main object of the present invention is to provide a server that can automatically restart the server when it is down, so as to facilitate the detection and recovery of the restarted service of the failed server. System and method for waiting for server failure, thereby reducing

首先二如步驟SI 〇〇,電源控制電路30中之計數器31之 計數值在^每一秒(既定單位時間)之後,將計數值減去一 (第二既定^值)。之後,如步驟31〇2,判斷此計數值是否 等於零(第三,既定數值),如果計數值不等於零的話,則如 步驟S 1 〇 4,,斷是否有接收到由事件訊號攔截模組2 〇所 送之一計數器重設信號。 若電源控制電路3 0沒有接收到計數器重設信號,則直 接回到步=S/ 0 〇的程序;而若電源控制電路3 〇有接收到 數器重設信號的話,則如步驟s丨0 6,將計數器3丨之計數^ 重新設回180(第一既定數值),再繼續回到步驟§1〇〇的程 序。 另一方面,在步驟51〇2的判斷中,如果計數值等於零 的話,則如步驟S 1 0 8,電源控制電路3 0關閉伺服器之電 源,並將伺服器重新開機,並輸出一故障發生信號(第2圖 中未顯示)’如傳訊(Pager )來通知系統管理人員。 因此’藉由本發明所提供之一種偵測與回復伺服器故 障之系統及方法,可以當伺服器當機時,同時自動通二管 理人員與自動將伺服器重新開機,以便利故障之伺服器^ 最短的時間内重新啟動以恢復服務,進而減少因為伺服器 停止服務後所產生的損失。 雖然本發明已以較佳實施例揭露如上,然其並非用以 限定本發明,任何熟悉此項技藝者,在不脫離本發明之精 神和範圍内’當可做些許更動與潤飾’因此本發明之保護 範圍當視後附之申請專利範圍所界定者為準。 °First, as in step SI 00, the count value of the counter 31 in the power control circuit 30 is reduced by one every second (predetermined unit time) (a second predetermined value). Then, as in step 31〇2, it is determined whether the count value is equal to zero (third, a predetermined value). If the count value is not equal to zero, then in step S1〇4, it is determined whether an event signal interception module 2 has been received. 〇 One of the counter reset signals sent. If the power control circuit 30 does not receive the counter reset signal, it directly returns to the procedure of step = S / 0 〇; and if the power control circuit 30 receives the counter reset signal, it proceeds to step s0 0 , Reset the count ^ of the counter 3 丨 to 180 (the first predetermined value), and then continue to the procedure of step §100. On the other hand, if the count value is equal to zero in step 5102, then in step S108, the power control circuit 30 turns off the power of the server, restarts the server, and outputs a fault. Signals (not shown in Figure 2) ', such as Pager, to notify system administrators. Therefore, with the system and method for detecting and recovering a server failure provided by the present invention, when the server is down, the administrator and the server can be automatically restarted at the same time to facilitate the failed server ^ Restart in the shortest time to restore service, thereby reducing losses due to server outages. Although the present invention has been disclosed in the preferred embodiment as above, it is not intended to limit the present invention. Anyone skilled in the art can 'do some changes and retouching' without departing from the spirit and scope of the present invention. The scope of protection shall be determined by the scope of the attached patent application. °
