Embodiment Construction
[0021] The present invention will be further described below in conjunction with the accompanying drawings.
[0022] see figure 1 , a fuse life test system with remote information transmission and control functions, including a local system unit 1, a network system unit 2 and a remote system unit 3, the local system unit 1 is implemented using the prior art, specifically including a life test module, Data acquisition module, life evaluation module, human-computer interaction module, temperature measurement module. The following is a brief description of each module: the life test module is connected with the fuse to be tested, and can provide an accelerated stress test environment for a fuse group formed by multiple fuses to be tested in series. The life test module mainly includes a central control unit, sampling Unit, detection and isolation unit, drive unit, execution unit, the specific composition and working method of the life test module refer to the Chinese patent...

The invention discloses a fuse life test system with remote information transmission and control functions, which includes a local system unit, a network system unit and a remote system unit, and the local data information of each module in the local system unit can be transmitted to the The remote display module of the remote system unit displays, and can send text messages to the mobile phone of the on-duty personnel through the SMS interaction module of the mobile phone, so that the on-duty personnel can know the current working status of each fuse sample (such as whether it is blown) at the first time, and whether there is any abnormality in the system and whether the test meets the cut-off condition. When it is found that the remote display module outputs an alarm message corresponding to an abnormal state, or receives an alarm message through a mobile phone message, the staff does not have to rush to the test site, but can remotely cut off or connect the system power supply through the remote control module or the mobile phone message interaction module. Resolve exceptions.
Description
technical field [0001] The invention relates to a fuse life test system, in particular to a fuse life test system with remote information transmission and control functions. Background technique [0002] A fuse is an electrical component installed in a circuit to ensure the safe operation of the circuit. Its core is a melt, which plays the role of cutting off the current when it is blown. When the current flows through the melt, the melt with a certain resistance value will generate heat, and the heat generation is proportional to the square of the current. When the circuit fails or is abnormal and the current continues to increase, the heat generation of the melt will increase until the circuit is disconnected by fusing, which plays a protective role. [0003] Before this patent, the applicant had previously applied for patents "Intelligent Fuse Life Test System" (publication number: CN101793943A), "fuse life characteristic data test and evaluation system and its evaluati...
