Embodiment 1

[0039] Such as figure 1 As shown, a real-time current-based medical equipment fault detection system in this embodiment includes a current detection module, a processing module and a wireless module.

[0040] The current detection module is used to collect the input current of the equipment in real time. In this embodiment, the current detection module adopts a PZEM-002 electric power monitor with a working voltage of 80-260V and a current of 20A, which can meet the detection requirements of general medical equipment. When in use, connect the current detection module in series with the power line of the medical equipment to be detected.

[0041] The processing module includes a processing unit and a storage unit. The storage unit is used to store the fault current characteristics; the fault current characteristics include the fault current waveform data from before the fault occurs to the moment when the fault occurs; the processing unit is used to obtain the input current fr...

Embodiment 2

[0049] The difference between this embodiment and Embodiment 1 is that in this embodiment, a real-time current-based medical equipment fault detection system also includes a terminal module and / or a central server, both of which are used to receive the information sent by the wireless module. critical result. In this embodiment, all of the above are included.

[0050]In this embodiment, a real-time current-based medical device fault detection method further includes step S4, where the terminal module and / or the central server are used to receive the judgment result sent by the wireless module.

Embodiment 3

[0052] The difference between this embodiment and Embodiment 2 is that in this embodiment, in a real-time current-based medical equipment fault detection system, the storage unit uses a Flash chip. The central server is also used to send fault current feature update information to the wireless module, and the processing unit is used to update the fault current feature in the storage unit according to the fault current feature update information.

Abstract

The invention relates to the field of equipment maintenance, and particularly discloses a medical equipment fault detection system and method based on real-time current. The system comprises: a current detection module, which is used for collecting the input current of equipment in real time; a processing module, which is used for acquiring the input current from the current detection module, comparing and analyzing the input current and a pre-stored fault current characteristic, judging whether the equipment has a fault at present, and outputting a judgment result; and a wireless module, which is used for sending a judgment result to the outside when the equipment breaks down. The technical scheme adopted by the invention can detect the current change of the medical equipment in real timeand automatically judge the fault type.

Description

technical field [0001] The invention relates to the field of equipment maintenance, in particular to a medical equipment fault detection system and method based on real-time current. Background technique [0002] At present, the way to deal with faulty equipment is to repair after the event, that is, to check the equipment phenomenon, fault location and reverse the cause of the fault after the fault occurs, and finally give the fault solution. Such a processing method results in much time-consuming and low efficiency from fault discovery to troubleshooting. [0003] At present, no matter whether it is a large tertiary hospital, a second-level hospital or a community hospital, there are many medical equipment, and they are all facing great pressure on equipment maintenance and guarantee. Due to the rapid growth of equipment and the shortage of maintenance engineers, it is difficult to meet the needs of these hospitals in the traditional way of after-the-fact maintenance to d...
