Abstract
The utility model discloses a single-pole gate controlled based on a PLC (Programmable Logic Controller) and belongs to the field of gateway control. The gate comprises an enclosure, a PLC, a stepping motor, an intercepting rod, a card reading module and a plurality of diffuse reflection sensors located at the outer side of the enclosure, wherein the PLC controls the stepping motor to work through a pulse signal; and the stepping motor is connected with the end part of the intercepting rod. When no body swipes a card, a gate channel is at a closed state and the intercepting rod is horizontally stopped in the channel. When someone swipes the card, the card reading module detects a card swiping signal and notifies the PLC through a serial communication manner; and the PLC controls the stepping motor to clockwise rotate for 90 degrees and the intercepting rod is recycled to open the channel. When the diffuse reflection sensors detect that someone passes through the channel, the PLC controls the stepping motor to anticlockwise rotate for 90 degrees so that the intercepting rod recovers a horizontal position and the channel is closed.
Description
Technical field
The utility model relates to a kind of single pole gate based on PLC control, belongs to control field, lock road.
Background technology
Gate is pass gates again, is a kind of passage arrester, is used for the management stream of people and standard personnel and comes in and goes out.Now, have a lot of large-scale factories all to use gate as gate control system, the employee need brush employee job card just can enter factory.Existing gate adopts industrial computer as main control unit mostly, adopts the fan door as the passage arrester, and production cost is higher.
The utility model content
The utility model in the background technology problem, a kind of single pole gate based on PLC control is proposed, this gate has stable performance, characteristics with low cost.
The utility model adopts following technical scheme for overcoming the above problems:
A kind of single pole gate based on PLC control, several diffuse reflection sensors that comprise casing, PLC controller, stepper motor, interception bar, card reading module and be positioned at the casing outside; Described PLC controller is by pulse signal control step machine operation; Described stepper motor is connected with the end of interception bar; Described card reading module is connected by serial port communication line with the PLC controller; Described diffuse reflection sensor is connected with the input end of PLC controller respectively.
As scheme optimization, the top of described casing also is provided with alarm lamp; Described alarm lamp is connected with the output terminal of PLC controller.
Technique effect:
1, adopt PLC as main control module, dependable performance, antijamming capability is strong.
2, control principle is simple, and is with low cost, has good market outlook.
3, outward appearance simplicity generosity has good visual effect.

Label title among Fig. 1, Fig. 2: 1, casing; 2, PLC controller; 3, stepper motor; 4, interception bar; 5, diffuse reflection sensor; 6, card reading module; 7, alarm lamp.
Embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is done introduction in further detail:
Structure of the present utility model comprises casing 1, PLC controller 2, stepper motor 3, interception bar 4, card reading module 6 and several diffuse reflection sensors 5 that are positioned at casing 1 outside as shown in Figure 1; Described PLC controller 2 is by 3 work of pulse signal control step motor; Described stepper motor 3 is connected with the end of interception bar 4, and the rotation of tackling bar 4 by control realizes opening wide or closing of passage; The top of described casing 1 also is provided with alarm lamp 7.
Circuit structure of the present utility model as shown in Figure 3, described card reading module 6 and PLC controller 2 are connected by serial port communication line, are used for realizing function of swiping card; Described diffuse reflection sensor 5 is connected with the input end of PLC controller 2 respectively, for detection of the current state of personnel in the passage; Described alarm lamp 7 is connected with the output terminal of PLC controller 2, is used for realizing warning function.
When nobody swiped the card, the gate passage was in closed condition, and interception bar 4 levels are blocked in the passage.When someone swiped the card, card reading module 6 detects swiped the card signal and notifies PLC controller 2 by the mode of serial communication, and 3 dextrorotations of PLC controller 2 control step motors turn 90 degrees, and will tackle bar 4 and regain, and make passage open wide (as shown in Figure 2).After diffuse reflection sensor 5 detected the someone and passes through passage, PLC controller 2 control step motors 3 were rotated counterclockwise 90 degree, made interception bar 4 return to horizontal level, pathway closure.Just do not thrust oneself in passage if someone swipes the card, diffuse reflection sensor 5 can be passed to PLC controller 2 with induced signal, and control alarm lamp 7 glimmered after PLC controller 2 was received signal, to cause the relevant personnel's attention.
