In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
It is appreciated that term " first " used in this application, " second " etc. can be used to describe various elements herein,
But these elements should not be limited by these terms.These terms are only used to distinguish the first element from the other element.
The application provides the intelligence control system in a kind of data center computer room, which includes multiple control devices, the number
Multiple regions are divided into according to each column cabinet in computer room, the multiple region and the multiple control device correspond,
Each control device is used to control the lighting device in data center computer room in corresponding region.For example, including 40 in a column cabinet
A control device is arranged using every 5 cabinets in a column cabinet as a region to control the photograph in this region in cabinet
Bright device, such column cabinet need to be divided into 8 regions, need 8 control devices altogether.
As shown in Figure 1, each control device include sequentially connected gravity sensor 1, relay control module 2 and after
Electric appliance 3；Wherein:
The gravity sensor 1, is arranged on the ground of corresponding region, the pressure being subject to for detecting corresponding region ground
Value generates corresponding electric signal according to the pressure value, and the electric signal is sent to the relay control module 2；
The relay control module 2, for generating corresponding relay control signal according to the electric signal, and by institute
It states relay control signal and is sent to the relay 3；
The relay 3 connects the lighting device in corresponding region, for according to relay control signal control pair
Answer the light on and off of the lighting device in region.
For example, when nobody steps on the ground provided with gravity sensor 1, pressure that gravity sensor 1 detects
Power is 0 or very little, and when someone steps on the ground provided with gravity sensor 1, the pressure that gravity sensor 1 detects becomes
Greatly, the electric signal that gravity sensor 1 can be different according to different pressing creations, and then relay control module 2 is according to different
Electric signal generates different relay control signals, and the contact of different relay control signal control relays 3 enters difference
State, different contacts status can control the light on and off of lighting device.
In some embodiments, the gravity sensor 1 may include the first output end and second output terminal, the gravity
Inductor 1 is specifically used for: the pressure value that detection corresponding region ground is subject to passes through if the pressure value is greater than preset threshold
First output end exports the first level, if the pressure value is less than or equal to the preset threshold, passes through described second
Output end exports second electrical level.
It will be appreciated that when pressure value is greater than preset threshold, it is believed that someone, which has stepped on, is arranged gravity sensor 1
On ground, and it can consider that nobody steps on when pressure value is less than or equal to the preset threshold and gravity sensor 1 be set
On ground.First level is high level and second electrical level is low level, alternatively, the first level is low level and second electrical level is high
Level.For example, with reference to Fig. 2, gravity sensor 1 can use SY-8411L-D, and 2 pins can export low level, and 5 pins can
To export high level, different level is exported by different pins, i.e., the first output end can be 5 pins at this time, and second is defeated
Outlet can be 2 pins, be highly convenient for distinguishing.From figure 2 it can be seen that 1 pin and 6 pins of SY-8411L-D are hanging, 2 pipes
Foot and 5 pins connect subsequent conditioning circuit, and 3 pins connect driving voltage, 4 pins ground connection.
Here gravity sensor exports two different level using two output ends, certainly can also be using only one
The gravity sensor of a output end.
In some embodiments, referring to fig. 2, the relay control module 2 may include:
AD conversion unit 21, for converting corresponding digital signal for the electric signal；
Signal generation unit 22 is controlled, is connect with the output end of the AD conversion unit 21, in the digital signal
To export first control signal when the first preset number signal, the is exported when the digital signal is the second preset number signal
Two control signals；Wherein, the first preset number signal is the first control described in the corresponding digital signal of first level
Signal be control the relay 3 contact R L be closed state signal, the second preset number signal be described second
The corresponding digital signal of level, the second control signal be control the relay 3 contact R L be off-state signal；
When the contact R L of the relay 3 enters closed state, the lighting device that the relay 3 connects is lighted, the relay 3
When contact R L enters off-state, the lighting device that the relay 3 connects is knocked out.
That is, when gravity sensor 1 exports the first level, control signal generation unit 22 output the first control letter
Number, which can control the contact R L closure of relay 3, so that it is bright for controlling lighting device；In the output of gravity sensor 1 the
When two level, control signal generation unit 22 exports second control signal, and the contact R L of the signal control relay 3 is disconnected, from
And controlling lighting device is to go out.In contact R L closure, the circuit closed of lighting device, therefore lighting device is lighted, in contact R L
When disconnection, the circuit of lighting device is disconnected, therefore lighting device knocks out.
It will be appreciated that when the signal that control signal generation unit 22 receives is the corresponding digital signal of the first level
When, it is known that the pressure that ground is subject at this time is greater than preset threshold, i.e. someone steps on the ground provided with gravity sensor 1, this
When need that lighting device is made to brighten, that is, need to make the contact R L of relay 3 to be closed, thus control signal generation unit 22 output control
The contact R L for making the relay 3 enters the first control signal of closed state.It is received when control signal generation unit 22
When signal is second electrical level corresponding digital signal, it is known that the pressure that ground is subject at this time is less than or equal to preset threshold, that is, does not have
Someone steps on the ground provided with gravity sensor 1, does not need that lighting device is made to brighten at this time, that is, needs to make relay 3
Contact R L is disconnected, so the contact R L that the control output of signal generation unit 22 controls the relay 3 enters the of off-state
Two control signals.
Wherein, control signal generation unit 22 can be using AT89C51 system (without integrated in AT89C51 system
Converter), AD conversion unit 21 and control signal generation unit 22 are two independent modules, i.e., the described control signal at this time
Generation unit 22 is the single-chip microcontroller independently of the AD conversion unit 21 (for example, ASDC0809).Certainly, some single-chip microcontroller (examples
Such as, STC89C51) in be integrated with converter, at this time AD conversion unit 21 and control signal generation unit 22 be integrated into
The single-chip microcontroller of one.The pre-configured programmed logic on single-chip microcontroller, can export pair when receiving different input signals
The control signal answered.
In some embodiments, movement is just had since relay coil needs to flow through biggish electric current (for example, 50mA),
Therefore one current amplification circuit 242 can be set before relay 3.That is, referring to fig. 2, the relay control module 2 is also
May include: the first amplifying unit 23, be arranged in it is described control signal generation unit 22 output end and the relay 3 it is defeated

In practical applications, control signal generation unit 22 specific structure can there are many, one of which is described below
Structure: the first amplifying unit 23 includes triode Q1, first resistor R1 and second resistance R2；Wherein: the first resistor R1 is set
It sets between the input terminal of first amplifying unit 23 and the base stage of the triode Q1, the second resistance R2 is arranged in institute
It states between the base stage and ground terminal of triode Q1, the emitter of the triode Q1 connects the ground terminal, the triode Q1
Extremely described first amplifying unit 23 of current collection output end；The resistance value of the first resistor R1 and the second resistance R2 can
The triode Q1 is set to enter saturation shape when the input terminal of first amplifying unit 23 receives the first control signal
State makes the triode Q1 enter cut-off when the input terminal of first amplifying unit 23 receives the second control signal
State.
Wherein, the value of first resistor R1 and second resistance R2 must satisfy: in the input of first amplifying unit 23
Termination makes the triode Q1 enter saturation state when receiving the first control signal, in the defeated of first amplifying unit 23
Entering makes the triode Q1 enter off state when termination receives the second control signal, specific value can be according to reality
Situation determines.
It will be appreciated that relay coil is arranged between the collector and positive supply of triode Q1, therefore relay coil
Collector load as triode Q1.When the first amplifying unit 23 inputs second control signal, triode Q1 is cut-off, after
Electric apparatus coil no current passes through, then contact R L is disconnected, and then lighting apparatus does not work；When the first control of the first amplifying unit 23 input
When signal, triode Q1 is saturated, and has comparable electric current to pass through on relay coil, and contact R L is closed at this time, and then lighting device
It lights.
It will be appreciated that due to when gravity sensor 1 exports the first level needing that triode Q1 is made to enter saturation shape
State, and then lighting device is lighted, and need formula triode Q1 to enter off state when gravity sensor 1 exports second electrical level,
And then knock out lighting device.And since triode Q1 has different types, to meet requirements above, in the kind of selection triode Q1
Need to consider which is high level in the first level and second electrical level when class, which is low level.If the first level is
High level and second electrical level are low level, and triode Q1 should be NPN triode at this time；And if the first level is low level and the
Two level are high level, and triode Q1 should be PNP triode at this time.
Certainly, the first amplifying circuit 242 not only can realize Current amplifier using triode Q1, can also use other devices
Part realizes Current amplifier, for example, metal-oxide-semiconductor, darlington array ULN2003 etc..
In some embodiments, the electric signal that gravity sensor 1 exports may be fainter, it is therefore desirable to gravity sensing
The electric signal that device 1 exports amplifies, and thus referring to fig. 2, the relay control module 2 can also include: the second amplification list
Member 24, is arranged between the output end of the gravity sensor 1 and the input terminal of the converter, for the gravity-feed tank
The electric signal for answering device 1 to export amplifies.
In practical applications, there are many specific structures of the second amplifying unit 24, when there are two outputs for the tool of gravity sensor 1
When end, referring to fig. 2, the second amplifying unit 24 can be using such as flowering structure: second amplifying unit 24 includes: or 241 He of door
Amplifying circuit 242, described or door 241 first input end connect the first output end of the gravity sensor 1, described or door
241 the second input terminal connects the second output terminal of the gravity sensor 1, puts described in described or door 241 output end connection
The input terminal of big circuit 242.
It will be appreciated that when the tool of gravity sensor 1 is there are two output end, for example, 2 pins of SY-8411L-D can be defeated
Low level out, 5 pins can export high level, when 2 pins export low level, need to 242 input low level of amplifying circuit,
When 5 pins export high level, need to 242 input high level of amplifying circuit, therefore in gravity sensor 1 and amplifying circuit
One or 241 are set between 242, the electric signal that two pins of weight induction device export is input to amplifying circuit 242
In one input terminal.It will be appreciated that there is no need in gravity sensor 1 when if gravity sensor 1 is with an output end
Increase or door 241 between amplifying circuit 242.
Wherein, referring to fig. 2, the specific structure of amplifying circuit 242 can be with are as follows: amplifying circuit 242 includes operational amplifier, electricity
Hinder Rx and resistance Ry；Resistance Rx be arranged in the operational amplifier reverse input end and the operational amplifier output end it
Between, resistance Ry is arranged between the reverse input end and ground terminal of the operational amplifier.The non-inverting input terminal of operational amplifier
For the input terminal of amplifying circuit 242, the output end of operational amplifier is the output end of amplifying circuit 242.
Wherein, operational amplifier can be input to operational amplifier using the signal that amplifier in the same direction or door 241 export
Input terminal, according to the operational formula of amplifier in the same direction: Vout=Vin* (Rx+Ry)/Ry can pass through the resistance value of setting Rx and Ry
The multiple of amplification is arranged.
In some embodiments, referring to fig. 2, the relay 3 may include freewheeling diode 31 and relay coil, institute
It states freewheeling diode 31 and the relay coil is arranged in parallel, and be arranged at the input terminal and forward direction electricity of the relay 3
Between source, contact R L corresponding with the relay coil is arranged in the circuit of lighting device.
It will be appreciated that triode Q1 is by being saturated when the signal for being input to triode Q1 becomes low level from high level
Become ending, the electric current in such 3 inductance coil of relay loses the access of circulation suddenly, if depositing without freewheeling diode 31
, then biggish inverse electromotive force will be generated at relay coil both ends, to be lower just upper negative, voltage value lies prostrate polarity up to more than 100,
This voltage, which adds when positive power supply acts on the collector of triode Q1, can damage triode Q1, therefore the work of triode Q1
With being that this inverse electromotive force is discharged by the direction of arrow meaning, so that the voltage highest of the collector of triode Q1 over the ground
No more than the voltage of the high level of input, to achieve the purpose that protect triode Q1.
