Abstract
Provided is a guest room controller with a forced-on relay, so that an illuminating lamp in a guest room can be turned on as needed under the condition of commercial power. The guest room controller is characterized in that a self-locking key and a Darlington matrix circuit are added to the guest room controller; a CPU microprocessor is connected with a power supply, the self-locking key and a power logic device; the self-locking key is connected to the input end of a Darlington matrix; and the output end of the Darlington matrix is connected to a coil of the relay. Power is input to the input end of the Darlington matrix through the self-locking key, and one level is output to the coil of the relay to control the on/off state of the relay, so that the load illuminating lamp is controlled to be turned on/off.
Description
One, art
Patent of the present invention relates to a kind of intelligent guest room controller, particularly relates to a kind of guest-room controller with forcing open relay.
Two, background technology
Along with expanding economy, hotel industry is just progressively marched toward intellectuality, existing guest room control system collection signal light control, and airconditioning control is in one.But when system debugging in early stage and the system failure, the light fixture in guest room can not normally use.Current guest room control system, due to lighting connecting system during debugging in early stage, but does not complete due to system program, lighting in guest room can not be used, bring very burden to commissioning staff; During later stage uses, work as system malfunctions, when guest-room controller is not controlled, in guest room, lighting also can not normally use, and can cause very large puzzlement for the person of moving in.
Three, summary of the invention
For to solve in existing guest room control system existing debugging in early stage and when the system failure, normally can not use this problem of indoor illumination light fitting, the invention provides a kind of guest-room controller with pressure open relay.This guest-room controller when there being civil power, can provide normal illumination.
The technical solution adopted for the present invention to solve the technical problems is: the mode that controller adopts Darlington matrix and self-locking button to cooperatively interact, when civil power is normal, press self-locking button, switch on power to Darlington matrix power, Darlington internal matrix is 8 triodes arranged side by side, when transistor base is high level, export as low level, the output of Darlington matrix is connected to the coil of relay, coil obtains electric, thus relay adhesive, connect load, lighting is lighted.No matter be debugging in early stage, or when controller is abnormal, all can when there being civil power, power to Darlington transistor by connecting self-locking button, thus relay coil obtains electric, the load in lighting loop will be opened, and can normally use.
The invention has the beneficial effects as follows, the lighting load during debugging in early stage of objective Ore-controlling Role normally can be used, facilitate commissioning staff to debug, improve debugging efficiency; When later stage controller failure, staff can positive opening relay, for guest room provides illumination, does not conveniently move in person and changes room, improves the service of hotel side, also for subsequent maintenance provides illumination, improves maintenance efficiency.

Four, embodiment
In Fig. 1, a kind of guest-room controller with forcing open relay, mainly comprise CPU microprocessor 1, clock controller 2, bus circuit 3, RS232 interface circuit 4, memory 5, shift-register circuit 6, power circuit 7, self-locking button 8, Darlington matrix 9, relay circuit 10, logical power chip 11, digital input circuit 12.CPU microprocessor 1 is responsible for process and receives various data, and memory 5 is used for storing the data received and after process; Clock controller 2 provides system clock, for various timing; Bus circuit 3 is used as system bus, for linking of each controller and host computer; RS232 interface 4 is for the download of program; Shift register 6 is for the infrared reception in guest room; Power supply power supply 7 provides operating voltage to each chip; Power logic device 11 provides logic low and high level to relay coil, the break-make of control relay, thus the switch of control load; Self-locking button 8, Darlington matrix 9 are used to provide fixed level to relay coil, make relay be in attracting state always, make lighting be in normal bright state.
Power circuit 7 in Fig. 2, self-locking button 8, Darlington matrix 9 and relay circuit 10 are the Key Circuit of inventing, and self-locking button 8 is access failure power supply when not pressing down, relay 10 is by the control of CPU microprocessor 1, and CPU microprocessor 1 is by logical power chip 11 control relay state.When self-locking button 8 is pressed, now connected the input of 12v power supply to Darlington matrix 9, GND is switched to Darlington matrix 9 logically, according to the internal structure principle of Darlington matrix 9, now Darlington matrix 9 exports as low level, and relay adhesive, load is opened.
Fig. 3 is the cut-away view of Darlington matrix 9, can refer to " electronic circuit " Electronic Industry Press and publishes.
