DETAILED DESCRIPTION
[0016] For the purpose of making the content of the present application more easily understood, the present application is further described in detail below according to the specific embodiments and in conjunction with the accompanying drawings.
[0017] Figure 1 A schematic diagram of the intelligent street lamp control system based on the network module provided in the present application is shown in the figure. The system includes a network control module, a relay module, a contactor module, and a power module. The network control module receives the remote control signal transmitted by the master control end, controls the relay module to operate, and makes the contactor coil of the contactor module be powered on or powered off, so as to make the contactor contact in series in the street lamp control loop be closed or opened, thereby realizing the remote control of the street lamp.
[0018] Specifically, the network control module receives the remote control instruction transmitted by the remote control terminal, and controls the relay module to operate. The network control module supports the MQTT / HTTP protocol.
[0019] In the present embodiment, the network control module includes an ESP32 module or a 4G DTU module.
[0020] The relay module includes a low-power relay, which is controlled by the network control module and outputs a 12V DC signal.
[0021] Preferably, optical coupling isolation is adopted between the network control module and the relay module.
[0022] The contactor module includes a contactor coil and a contactor contact. The contactor coil is connected with the relay module and is controlled by the relay module to be powered on or powered off. The contactor contact is connected in series in the street lamp control loop. At this time, the contactor contact is equivalent to the control switch of the street lamp control loop. When the contactor coil is powered on, the contactor contact is closed, at this time, the street lamp control loop is turned on, and the street lamp is on; when the contactor coil is powered off, the contactor contact is opened, at this time, the street lamp control loop is disconnected, and the street lamp is off.
[0023] It should be noted that the network control module only controls the low-power relay, which can avoid strong electric interference, and the contactor module serves as the control of the high-power load and bears the large current.
[0024] Meanwhile, the contactor module also has the expansibility and supports the PWM dimming of the photosensitive sensor.
[0025] The power module is used for supplying power for the network control module and the relay module.
[0026] In addition, the intelligent street lamp control system based on the network module further comprises a cloud management module connected with the network control module, and is used for realizing data interaction between the two, and then realizing remote monitoring and fault diagnosis.
[0027] The embodiment of the present application further provides an intelligent street lamp control method based on a network module, which is based on the intelligent street lamp control system based on the network module. Step S101: The network control module receives the remote control instruction sent by the host end. Step S102: The network control module controls the relay module to supply power or cut off power for the contactor coil. Step S103: The contactor coil is driven by the relay module, so that the contactor contact is closed or opened, the street lamp control loop is turned on or turned off, and the street lamp remote control is realized.
[0028] Therefore, the technical scheme of the present application realizes the remote control of the street lamp by controlling the relay module to operate through the network control module, and controlling the operating state of the contactor module through the relay module. In the above control logic, the network control module only controls the low-power relay, avoids strong electric interference, and bears the large current switch through the contactor module, so that the service life can be improved by more than three times. At the same time, the combination of the contactor module and the relay module is used to control the street lamp, and the cost is 30% lower than that of the intelligent circuit breaker.
[0029] In addition to the above-mentioned embodiments, the present application can have other implementation manners; any technical scheme formed by equivalent replacement or equivalent transformation falls within the protection scope required by the present application.
