The utility model so can communicate by letter with the central management PC by the mode of wireless networking, need not wiring owing to comprise main control MCU and wireless transceiver circuit, and is easy for installation, uses manpower and material resources sparingly.
The advantage of the gate control system that the utility model and central management PC are formed is:
1. traditional cable network gate control system installation work amount is big, and netting twine is subject to the people and destroys, and destroy not easy-to-search of trouble spot, back, and the gate control system of wireless networking can be evaded above problem, and it is interconnected, easy for installation that management end and each gate inhibition's terminal are passed through wireless network.
2. adopt traditional wired networking (such as 485 networkings etc.), if the communication link of node existing problems can have influence on the communication of overall network, and adopt wireless networking, single node damages the communication that can not influence whole network, and the system communication robustness is good.
3. system compatibility and expansibility are good, traditional wired networking mode is when increasing gate inhibition's terminal node newly, again topological network changes the network form, and adopts the wireless networking mode, when increasing node newly, in the zone of node in the network coverage, only need in network in the management end software communication of new registration ID number, just can realize interconnected, can not influence the total arrangement and the structure of network, newly-increased node is flexible.
Description of drawings:
Fig. 1 is the frame structure synoptic diagram of the utility model embodiment;
Fig. 2 is the primary control program process flow diagram of the utility model embodiment.
Embodiment:
The CONSTRUCTED SPECIFICATION of the utility model embodiment is described in detail in detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model comprises main control MCU, IC-card card reader, memory circuit, circuit driven by electromagnetic means, electromagnetic lock, clock circuit, LED display circuit, warning circuit and wireless transceiver circuit, described main control MCU connects IC-card card reader, memory circuit, circuit driven by electromagnetic means, clock circuit, LED display circuit, warning circuit and wireless transceiver circuit respectively, and described circuit driven by electromagnetic means connects electromagnetic lock.
Main control MCU adopts microprocessor chip, bears IC-card scanning and read-write, and with the radio communication and the data transmission of central management PC management end, and the legitimacy of IC gate inhibition's card is differentiated functions such as recording storage; The IC-card card reader mainly is the signal of IC-card in the intermittent scanning zone, if there is IC-card, just reads corresponding information and pays MCU and discern; Wireless transceiver circuit mainly is responsible for the communications and data transmission of the utility model terminal node, adopts the NRF24L01 radio frequency chip, and communications band is 2.4G.Memory circuit is mainly used to store the record that opens the door, and by reading the temporal information of clock circuit, additional period information is stored together, so that verify in the future, memory circuit adopts the CAT24WC64 storage chip of CATALYST company production as system film; Clock circuit is used to produce and the temporal information of additional gate inhibition record; Circuit driven by electromagnetic means adopts the ULN2003 chip for driving, and five locks, the three tongue linkage structures that electromagnetic lock is adopted international standards are the motor-driven Electromagnetic lock of axial type, and circuit driven by electromagnetic means drives the electromagnetic lock action.
As shown in Figure 2, be the primary control program process flow diagram of the utility model embodiment, at first carry out initialization after powering on, check whether cold start-up, if the internal memory self check is then carried out in cold start-up, and self-detection result exported with buzzer alarm circuit, otherwise skip self check, only the self-detection result preserved of output.Check whether power on for the first time then, if power on for the first time, host computer central management PC does not also pass parameter down, calls the default parameters subroutine.The setting of each address can only be after powering on, after handling above incident, program enters recurrent state, whether inquiry needs Card Reader processing, wireless communication process, other processing successively, if have, then enter in the corresponding processing subroutine, if Card Reader processing, wireless communication process, other processing are arranged, then corresponding the interruption can wake up procedure.
The utility model is unlatching according to control gate with the card number of user's IC-card, card has adopted sophisticated semiconductor manufacturing technology and information security technology, utilize electronic loop and inductive coil to produce special concussion frequency in card reader itself, when entering the card reader energy range, card produces resonance, induction current makes electronic loop transmit signals to card reader, to receive that through card reader conversion of signals becomes card data, and deliver to main control MCU and judge, make a strategic decision.
For the gate control system of the utility model and central management PC composition, the main control MCU of each gate inhibition's terminal all has a mutual different address number, distinguishes the sign of different gate inhibition's terminals as the central management PC.Before gate inhibition's terminal was enabled, at first to the prior every operational factor that is provided with of gate inhibition's terminal transmission, just can use to the user through after the above-mentioned initialization by gate inhibition's terminal through wireless communication interface for the central management PC.Usually gate inhibition's terminal is in waiting status, when people's Card Reader, card reader is transferred to the main control MCU of gate inhibition's terminal through its interface with card number, in main control MCU card number, card mode, current control time, current control module is compared, differentiates draw allowance whether result.This result is sent in the card reader, sends the acousto-optic indication to the Card Reader people.When the result was allowance, main control MCU drove electromagnetic lock by circuit driven by electromagnetic means and withdraws from the state of locking a door, and finishes the whole process that Card Reader opens the door.Simultaneously main control MCU becomes a logout to get off this process prescription, can incident uploaded when the central management PC is communicated by letter.
The central management PC of control center can be downloaded legal card number (or blacklist) to the utility model by the wireless networking mode, the utility model also can be uploaded to the central management PC by the Wireless Networking mode record (card number and time) that will open the door, can realize password and blacklist setting, gradable, timesharing control.
