Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] The gist of the present invention is to realize the self-verification of the security device through an online verification method, so that it can be applied to the management of the Internet of Things, which specifically includes the following steps:

[0032] (1) The management master station sends a verification instruction to the controller through a wireless signal;

[0033] (2) The controller sends a control signal according to the received verification instruction, connects the electronic control switch in the safety device with a through line, bypasses the electronic control switch from the control circuit, and avoids the disconnection issued by the safety device during the verification process. The signal affects the normal power transmission of the line, so as to realize the verification without power failure.

Abstract

The invention discloses a protector suitable for the Internet of Things and an online verification method thereof and belongs to the technical field of emergency protection circuit devices. The protector comprises a protector body comprising a current sensor and an electronic control switch, is characterized in that two ends of the electronic control switch are connected in parallel with a straight-through line, and the straight-through line is connected in series with a first switch; the protector further comprises a controller and a management master station, the management master station is in wireless communication with the controller, the controller is in control connection with a current generator, the current generator provides detection current for the current sensor through a second switch, the detection current adapts to rated action current of the protector body, and the controller controls on-off of the first switch and the second switch; the controller also detects an on-off state and the off response time of the electronic control switch, and determines whether the protector body is qualified or not according to the detection information. On the premise that normal transmission of electric energy in a power transmission line is not affected, the protector can automatically check whether the protector can reliably send out a cut-off signal or not under rated action current.

Description

technical field [0001] The invention belongs to the technical field of emergency protection circuit devices, and in particular relates to a security device suitable for the Internet of Things and an online verification method thereof. Background technique [0002] The safety device is also called a leakage protector or a leakage switch. It generally detects the zero-sequence current in the line through the primary coil of the current transformer. Under normal circumstances, the current in the line is the same in magnitude and opposite in direction, and its zero-sequence current is almost zero. When electric shock or other phenomena in the line lead to current leakage, the above balance will be destroyed, resulting in an induced current in the secondary coil, and based on the induced current, a control signal to automatically cut off the power supply is issued. Therefore, the security device is recognized as an effective protection device. [0003] At present, the low-voltag...
