Description
Technical Field
The utility model relates to a thing networking field, specific saying so relates to an intelligence fortune dimension remote control circuit for case in this field.
Background
The Chinese utility model patent CN209709755U discloses an intelligent operation and maintenance box, which comprises a box body, wherein a 220V access port is arranged on the box body, a 220V output port is arranged on the box body, and a control panel is arranged in the box body; the power supply box is characterized in that a communication assembly is arranged on the box body and comprises a power supply socket, an uplink port and a network port, the power supply socket, the uplink port and the network port are all arranged on the surface of the box body, and the power supply socket is electrically connected with the uplink port and the network port and is connected to the control panel. Although the intelligent operation and maintenance box realizes centralized and unified management of all the acquisition terminals, the upper computer can not remotely control all the loads after the power supply of the power grid is lost.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that an intelligence fortune dimension remote control circuit for case is provided.
In order to solve the technical problem, the utility model discloses a following technical scheme:
the utility model provides an intelligence fortune dimension remote control circuit for case, its improvement lies in: the intelligent operation and maintenance box comprises two diodes which are connected in parallel, the anode of one diode is electrically connected with a power grid power supply, the anode of the other diode is electrically connected with a backup power supply, the cathodes of the two diodes are electrically connected with a 24V power supply, the 24V power supply is electrically connected with a control center and supplies power to the control center, the control center is electrically connected with a relay driving chip and is communicated with an upper computer through a network card, and each load in the intelligent operation and maintenance box is electrically connected with an interface of the relay driving chip through a relay.
Furthermore, a backup power supply in the intelligent operation and maintenance box is electrically connected with a charger, and the charger is electrically connected with a power grid power supply and continuously charges the backup power supply.
Further, the backup power source is a super capacitor or a battery.
Furthermore, the control center is a singlechip.
Further, the model of the relay driving chip is ULN 2003A.
The utility model has the advantages that:
the utility model discloses an intelligence fortune dimension remote control circuit for case loses the back at the electric wire netting mains operated of intelligence fortune dimension case, can continue to be the control center power supply by the reserve power supply, makes it still can with host computer communication, and the host computer also can continue each load work of remote control. Based on the characteristic that the voltage of the power grid is slightly higher than that of the backup power supply, the power grid power supply is preferentially supplied with power by the power grid power supply under the condition that the power grid power supply is normal by utilizing the high-voltage selection characteristic of the diode, and the power grid power supply is automatically switched to the backup power supply for power supply after being lost.
Drawings
Fig. 1 is a schematic circuit connection diagram of a remote control circuit for an intelligent operation and maintenance box disclosed in embodiment 1 of the present invention;
fig. 2 is a pin diagram of the relay driver chip ULN2003A used in embodiment 1 of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present 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 merely illustrative of the invention and are not intended to limit the invention.
In the embodiment, the backup power supply 3 in the intelligent operation and maintenance box is electrically connected with the charger 11, and the charger is electrically connected with the power grid power supply and continuously charges the backup power supply. The backup power supply is a super capacitor or a battery. The control center is a singlechip. The model of the relay driver chip is ULN2003A, and a pin diagram of the relay driver chip is shown in FIG. 2.
The working process of the circuit disclosed by the embodiment is as follows: the two diodes which are connected in parallel can play a role in high voltage selection, when the power grid power supply is electrified, the voltage of the power grid power supply is higher than that of the backup power supply, the power grid power supply supplies power for the 24V power supply, the 24V power supply supplies power for the control center and each load in the intelligent operation and maintenance box, and when the backup power supply does not supply power, the backup power supply is continuously charged by the charger to enable the backup power supply to be in a floating state, so that the service life of the backup power supply is prolonged.
The control center is communicated with the upper computer through the network card so as to receive instructions sent by the upper computer, and the relay driving chip is controlled to open or close the relay electrically connected with the corresponding load according to the instructions, so that each load in the intelligent operation and maintenance box can operate or stop according to the remote instructions of the upper computer, and remote control is realized. After the power supply of the power grid is lost, the power supply can be automatically switched to a backup power supply to supply power, so that the control center in the intelligent operation and maintenance box can continuously work, and the upper computer can also continuously remotely control each load in the intelligent operation and maintenance box to work after the power supply of the power grid is lost.
