Abstract
The utility model discloses an isolation power circuit of a plant controller. The isolation power circuit comprises at least two wide voltage power isolation modules and at least two voltage stabilizers, wherein after being input, external power is connected with the two wide voltage power isolation modules respectively; each wide voltage power isolation module is connected with one voltage stabilizer and supplies working voltage to the voltage stabilizer; and the output end of each voltage stabilizer is connected with electric appliance equipment. By the isolation power circuit of the plant controller, one wide voltage power isolation module is used for supplying 12V voltage to one voltage stabilizer; meanwhile, the other wide voltage power isolation module supplies direct current (DC) 5V voltage to the other voltage stabilizer, therefore, the working voltage input by a power supply of a mainboard is wide, and phenomena of mixing and burning which are caused by mis-operation are avoided; the isolation power circuit is relatively high in anti-interference capacity; the service life of the power supply is prolonged; and the production cost is correspondingly reduced.
Description
Technical field
The utility model relates to a kind of plant controller insulating power supply circuit.
Background technology
Along with the development of China's agricultural science and technology, reading intelligent agriculture is come into people's life just gradually.Family expenses plant walls, senior office club plant walls, outdoor large landscape plant wall etc. are more and more, and plant walls is just progressively come into the different places such as family, high-end office space, vacation tourism place.And the power supply input service voltage of existing plant walls mainboard is narrower, and antijamming capability is relatively poor, if during operating personnel's misoperation, very easily causes mixed electricity to burn the unfavorable conditions such as sheet, has reduced power supply useful life, has correspondingly increased equipment cost.
The utility model content
The purpose of this utility model namely is to overcome the deficiencies in the prior art, and a kind of plant controller insulating power supply circuit is provided, and the power supply input service voltage of mainboard is wide, has prevented that the mixed electricity that misoperation causes from burning the situations such as sheet, has stronger antijamming capability.
The purpose of this utility model is achieved through the following technical solutions: plant controller insulating power supply circuit, it comprises at least two wide voltage source isolation modules and at least two pressurizers, be connected with two wide voltage source isolation modules respectively after the external power source input, each wide voltage source isolation module is connected with a pressurizer respectively, for pressurizer provides operating voltage, the output of pressurizer is connected with power consumption equipment.
The beneficial effects of the utility model are: the utility model provides a kind of plant controller insulating power supply circuit, the power supply input service voltage of mainboard is wide, prevented that the mixed electricity that misoperation causes from burning the situations such as sheet, has stronger antijamming capability, prolong power supply useful life, correspondingly reduced production cost.
Description of drawings
Fig. 1 is structured flowchart of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described, but protection range of the present utility model is not limited to the following stated.
As shown in Figure 1, plant controller insulating power supply circuit, it comprises at least two wide voltage source isolation modules and at least two pressurizers, be connected with two wide voltage source isolation modules respectively after the external power source input, each wide voltage source isolation module is connected with a pressurizer respectively, for pressurizer provides operating voltage, the output of pressurizer is connected with power consumption equipment.
The wide voltage source isolation module of the course of work of the present utility model: B1212SDC-DC provides 12V voltage for the ASM1117-5 pressurizer, the wide voltage source isolation module of B1205S provides DC5V voltage for the ASM1117-3.3 pressurizer, so that the power supply input service voltage of mainboard is wide, insulating power supply can prevent that the mixed electricity that misoperation causes from burning the situations such as sheet, and has stronger antijamming capability.
