Abstract
The utility model discloses a light return circuit intelligent control module, including LCD display screen, button, CPU and work power supply circuit, CPU connects LCD display screen, button, IV conversion equipment, VI output conversion equipment, VI conversion equipment, relay output device, DI input device, sample current input device and work power supply circuit respectively. The utility model discloses light loop control module can realize that the switch in return circuit, the control of realization illumiinance require, edit and use the scene, edit and use chronogenesis, longitude and latitude time schedule control, solve the too single shortcoming of module function, have zero passage judgement technique simultaneously, increased the life of inside relay, from taking short -circuit protection, to depend on the limitation of outside short -circuit protection equipment when solving the short circuit completely, from taking the signal input function, can gather on -the -spot incoming signal, like the fire alarm signal, light light intensity sensor signal, human sensing signal etc..
Description
Technical field
This utility model relates to a kind of control module, specifically a kind of lighting circuit intelligent control module.
Background technology
Existing lighting circuit intelligent control module function is the most single, only the Push And Release function in loop, and cannot be at mould
Realize on block, system control to be formed, it is necessary to coordinate the control of host computer, such as upper dynamo-electric brain, touch screen panel, button
Panel etc..
The shutoff in existing lighting circuit intelligent control module loop is bringing onto load switch off current, and relay contact has phenomenon of arc discharge,
In the course of time, relay contact can form matsurface, causes contact resistance to become big, forms vicious cycle, relay contact occur
Locking (switch can not be disconnected, and is bonded together), has a strong impact on the service life of product.
Short-circuit protection is not done, the protection facility of the outside that places one's entire reliance upon inside existing lighting circuit intelligent control module.If outward
Portion's protection facility lost efficacy or did not installed, and just had the risk of scaling loss route and equipment.
Existing lighting circuit intelligent control module there is loop output function, as to external sensor or passive switch point signal,
Must additional enlargement module.
Summary of the invention
The purpose of this utility model is to provide a kind of lighting circuit intelligent control module, to solve to propose in above-mentioned background technology
Problem.
For achieving the above object, this utility model following technical scheme of offer: a kind of lighting circuit intelligent control module, including
LCD display, button, CPU and working power circuit, described CPU connects LCD display respectively, button, I/V turn
Changing device, V/I output conversion device, V/I conversion equipment, relay output device, DI input equipment, sample rate current input dress
Put and working power circuit.
As further program of the utility model: described LCD display uses the LCD screen of 128X64, with described CPU
Connected by SPI interface.
As further program of the utility model: described button uses 5 contact buttons, passes through I/O port with described CPU
Connect.
As further program of the utility model: described I/V conversion equipment is by using sampling with high precision resistance, by 4-20mA
Current signal is connected to the input port of the inside AD of cpu chip by operational amplifier after being converted into voltage signal.
As further program of the utility model: described sample rate current input equipment is by using current sample chip by electric current
After sampling, more directly it is connected with the AD input port of CPU by operational amplifier.
As further program of the utility model: described relay output device is directly exported by the I/O port of cpu chip,
And carry out power amplification through driving chip, then drive output relay.
As further program of the utility model: described working power circuit by power conversion chip outside is inputted straight
Stream 24V voltage is converted to DC5V voltage.
Compared with prior art, the beneficial effects of the utility model are: this utility model lighting circuit control module is capable of
The switch in loop, realize illuminance and control to require, edit and call scene, edit and call sequential, longitude and latitude sequencing contro, solve
The shortcoming that certainly functions of modules is the most single；There is zero passage judgment technology simultaneously, add the service life of internal relay；Carry
Short-circuit protection, solves the limitation of external short circuit to be placed one's entire reliance upon protection equipment during short circuit；From band signal input work energy,
Can be with the input signal of collection site, such as fire alarm signal, illuminance sensor signal, human-induced signal etc..
