Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below with reference to fig. 1-3 and the embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The embodiment of the application discloses a multi-output solar charging and discharging controller. Referring to fig. 1, the multi-output solar charging and discharging controller includes a control module 1 and a multi-output line 2. The multi-output solar charging and discharging controller is usually used as a preset distributor arranged in a household, and is mainly used for converting mains supply and outputting various levels of voltage through the multi-output line 2 when the mains supply is connected into the household, so that power is provided for other external load equipment such as a plurality of household appliances. The control module 1 is connected with the multi-output circuit 2 to control the on-off of each output circuit.

In addition, the control module 1 has a storage unit 11 capable of storing data of other external load devices such as home appliances connected to the multi-output line 2. Specifically, during the use of other external load devices such as home appliances, various data generated can be uploaded and stored in the storage unit 11 for the user to copy.

It is understood that the multi-output solar charging and discharging controller should be maintained and overhauled periodically during use to maintain good power supply efficiency. Therefore, the multi-output solar charging and discharging controller in the embodiment of the application adopts a control mode of independently controlling the on-off state between each output line and the external voltage 3 connected with the output line to form a plurality of independent output power supplies, and further can reduce the influence of power failure on users to the maximum extent when the power failure occurs.

The embodiment of the application can realize multiple independent output power supplies, so that each independent output power supply is correspondingly controlled by the control module 1. Therefore, one output line and the control module 1 form a control subsystem. Since the operation principle of each control subsystem is the same, the embodiment of the present application only describes one control subsystem in detail.

The multiplexed output line 2 includes a plurality of output sockets 21 for supplying power to other external loads such as an accessed home appliance. The output socket 21 and the external voltage 3 connected with the output socket can be communicated to form a loop, so that the output socket 21 can lead out the external voltage 3, and other external load equipment such as household appliances can be connected. In consideration of the safety of the output socket 21, that is, when the loop formed by the output socket 21 and the external voltage 3 is conducted, to avoid the situation that a user accidentally touches the output socket 21 to cause an electric shock when the output socket 21 is not connected to other external load devices such as a household appliance, a switch element S should be further provided in the conducted loop to facilitate the control of the on-off state between the output socket 21 and the external voltage 3 connected thereto, thereby improving the safety of the output socket 21.

The switching element S is mainly used to control the on/off state between the output socket 21 and the external voltage 3 connected thereto, and when the output socket 21 is not connected to other external load devices such as a home appliance, the switching element S may be turned off so that the external voltage 3 is not drawn out when the output socket 21 is connected to the external voltage 3. Specifically, when the switching element S is in a closed state, the loop in which the output socket 21 is located is turned on, and the output socket 21 draws the external voltage 3, which can supply power to other external load devices such as an accessed household appliance; when the switching element S is in an open state, the circuit in which the output socket 21 is located is disconnected, and the output socket 21 does not draw the external voltage 3 and cannot supply power to other external load devices such as an accessed household appliance.

In order to realize the automatic control of the switching element S, each output line may further include a micro relay KM instead of the switching element S. The miniature relay KM is switched into the loop in which the output socket 21 and the external voltage 3 are located, i.e. the normally open contact of the miniature relay KM is switched into the loop in which the output socket 21 and the external voltage 3 are located. When the armature in the miniature relay KM is attracted to the electromagnet, the normally open contact is closed, so that a loop where the output socket 21 is located is conducted, and then the output socket 21 can lead out external voltage 3 for normal work of other external load equipment such as accessed household appliances. On the contrary, when the armature in the micro relay KM is far away from the electromagnet, i.e. the normally open contact is opened, so that the loop where the output socket 21 is located is open, the output socket 21 cannot draw the external voltage 3.

It can be understood that the multi-output solar charging and discharging controller in the embodiment of the present application may have two control modes, namely, a local control mode and a remote control mode, and the two modes may be switched. When switching to local control mode promptly, remote control is invalid to the field maintenance personnel of avoiding taking place the danger of electrocuteeing, and then has improved its security.

The power supply end is connected with an external voltage 3 and is supplied with power by the external voltage 3. The pin I/0 is connected to the miniature relay KM and is used for independently controlling the miniature relay KM correspondingly connected with the pin I/O so as to control the output socket 21 correspondingly controlled by the miniature relay KM.

Referring to fig. 1 and 2, the I/O pin of the CPLD may be connected to the micro relay KM through an opto-isolator U1 to achieve isolation of circuits of different voltage classes. The anode input end of the optical isolator U1 is connected with an I/O pin, the anode output end is connected with external voltage 3, the external voltage 3 supplies power to the output end of the optical isolator U1, and the cathode output end is connected with the miniature relay KM.

The control module 1 is connected with the plurality of switching keys 4, the plurality of switching keys 4 correspond to the plurality of output lines 2 one by one, and the control module 1 can control the on-off of each output line according to the plurality of switching keys 4. Specifically, the switch button 4 is connected to an input pin of the control module 1. When the switch key 4 is in an open state, the control module 1 controls the output socket 21 connected to the corresponding I/O pin, so that the corresponding output socket 21 is connected to the external voltage 3 and is turned on, and the output socket 21 corresponding to the switch key 4 can supply power. On the contrary, the switch button 4 is in the off state, and the output socket 21 corresponding to the switch button 4 does not output voltage. The local control mode enables control of multiple power supplies by manual control.

The communication interface is connected to the communication module 5 to receive a remote control command. When the CPU receives the remote control instruction, the CPU controls the CPLD to control the miniature relay KM. The main controller 13 and the communication module 5 can be connected in a wired, wireless and serial manner.

The multi-output solar charging and discharging controller may also be provided with a display module 6. The display module 6 is connected with the CPU and is used for displaying the operating state data of the output socket 21. When power is supplied to a certain output socket 21 by local control or remote control, the CPU can acquire the operating state of the output socket 21 through the CPLD, thereby displaying corresponding state data through the display module 6. The display module 6 may be an LCD display screen.

In the state of the local control mode, the embodiment of the present application may further include an emergency stop button 7. The emergency stop key 7 is connected with the auxiliary controller 12 and is used for controlling the working state of all the miniature relays KM by one key so as to control all the output sockets 21 to switch on or switch off the external voltage 3.

When the CPU receives that all the output sockets 21 are in a state of not outputting voltage, the CPU can control the I/O pin of the CPLD to be set to a low level, so as to reduce the probability of secondary electric shock, thereby improving the safety of the CPLD.
