Detailed Description
In order to make the technical problems, technical schemes and beneficial effects to be solved more clear, the invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
The relay is widely applied to air-conditioning products, for example, the relay is used for controlling the on-off of an external load so as to realize the effect of controlling strong electricity by weak electricity. However, the relay in the prior art has no function of feedback of the load signal, and cannot monitor and feed back the operation condition of the load during operation.
Therefore, in order to solve the technical problem that the relay in the prior art cannot monitor the operation condition of the feedback load, the invention provides a load feedback type relay device, which comprises:
the control end of the relay is connected with the signal output end of the controller, the controlled end of the relay is connected with an external load, and the control signal output by the controller drives the external load to operate through controlling the relay;
and the feedback circuit is connected with the controlled end of the relay and the signal detection end of the controller and transmits an electric signal generated when an external load operates to the controller.
Therefore, the invention optimizes the traditional relay, and compared with the traditional relay, the invention is additionally provided with the feedback circuit which is used for feeding back the electric signal during load operation to the controller, so that the load feedback type relay provided by the invention can monitor and feed back the operation condition of the load in real time under the working state.
The principles and structures of the present invention are described in detail below with reference to the drawings and the examples.
As shown in fig. 1 and 2, the present invention proposes a load feedback type relay device including:

and the feedback circuit is connected with the controlled end of the relay and the signal detection end of the controller, and transmits an electric signal generated when the external load operates to the controller, and the controller receives and analyzes the electric signal to acquire the operation condition of the load.
Specifically, as shown in fig. 1, in one embodiment, the relay includes: electromagnetic coil L3 and electromagnetic switch K1 that connect through electromagnetic coupling, electromagnetic coil L3 sets up the control end at the relay, and electromagnetic switch K1 sets up the controlled end at the relay. One end of the electromagnetic coil L3 is connected with the signal output end of the controller, the other end of the electromagnetic coil L3 is grounded, and two ends of the electromagnetic switch K1 are connected with an external load. The feedback circuit includes: a first coupling element and a second coupling element connected by electromagnetic coupling. The first coupling element is an electromagnetic coil L1, and the second coupling element is an electromagnetic coil L2. The electromagnetic coil L1 is connected with the electromagnetic switch K1 in series, one end of the electromagnetic coil L2 is grounded, the other end of the electromagnetic coil L2 is connected with a signal detection end of the controller, and a filter is connected between the electromagnetic coil L2 and the signal detection end of the controller.
Therefore, when the signal output end of the controller outputs a control signal (which may be a high level signal), the electromagnetic coil L3 is energized, the electromagnetic switch K1 is closed, and the external load operates, at this time, a voltage signal/current signal is generated on the electromagnetic coil L1, the voltage signal/current signal generated by the electromagnetic coil L1 is coupled to the electromagnetic coil L2, the voltage signal/current signal generated by the electromagnetic coil L1 is rectified and filtered by the filter, and then transmitted to the controller, and the controller analyzes the voltage signal/current signal to obtain information of the external load. Meanwhile, if the power supply is alternating current in the external load operation process, the voltage signal/current signal generated by the electromagnetic coil L1 in the external load operation process is continuously changed, and the controller can analyze the change condition of the signal to judge whether the external load operation condition is normal or not.
Specifically, as shown in fig. 2, in another embodiment, the relay includes: electromagnetic coil L3 and electromagnetic switch K1 that connect through electromagnetic coupling, electromagnetic coil L3 sets up the control end at the relay, and electromagnetic switch K1 sets up the controlled end at the relay, and electromagnetic coil L3's one end connection director's signal output part, electromagnetic coil L3's the other end ground connection, electromagnetic switch K1's both ends are connected external load. The feedback circuit includes: a first coupling element and a second coupling element connected by electromagnetic coupling.

Therefore, when the signal output end of the controller outputs a control signal (which can be a high-level signal), the electromagnetic coil L3 is electrified, the electromagnetic switch K1 is closed, and an external load operates, at this time, a voltage signal/current signal is generated when the electromagnetic switch K1 is closed, the voltage signal/current signal generated when the electromagnetic switch K1 is closed can be coupled to the electromagnetic coil L2, the voltage signal/current signal generated when the electromagnetic switch K1 is closed is rectified and filtered by the filter and then transmitted to the controller, the controller analyzes the voltage signal/current signal to acquire information of the external load, and the controller can judge whether the external load is in an operating state or in a shutdown state by judging whether the voltage signal/current signal is received.
