The present application first provides a gate device, as shown in fig. 1, fig. 1 is a schematic structural diagram of an embodiment of the gate device of the present application. The gate device (not shown) of the present embodiment includes: the infrared transceiver module comprises a main control module 10, a transceiver bus 20, at least two voltage dividing resistors R1 and at least two infrared transceiver modules 30; the main control module 10 is provided with a first I/O port a for outputting a control signal; one end of the transceiving bus 20 is connected to the first I/O port a, and inputs a voltage signal under the control of the control signal; at least two voltage dividing resistors R1 are serially arranged on the transceiving bus 20, and one end of the first voltage dividing resistor R1 is connected with the first I/O port a through the transceiving bus 20; the external transceiver module 30 is disposed corresponding to the voltage dividing resistor R1 and connected to the other end of the corresponding voltage dividing resistor R1, and the infrared transceiver module 30 automatically generates address information according to the voltage at the other end of the corresponding voltage dividing resistor R1 under the control of the control signal.
The main control module 10 of the present embodiment may be in the form of a simple circuit, a simple chip, an integrated circuit, or an integrated chip.
Different from the prior art, the present embodiment connects the voltage dividing resistor R1 in series on the transceiving bus 20, connects the infrared transceiving module 30 with the voltage dividing resistor R1, and automatically generates the address information of the infrared transceiving module 30 by using the voltage at the other end of the voltage dividing resistor R1; therefore, the present embodiment can realize address allocation and identification of the infrared transceiver module 30 on the transceiver bus 20 through a bus voltage dividing mechanism, and compared with the prior art that address allocation and identification are performed by using a dial switch or an extended I/O port, the present embodiment can simplify the hardware structure of the gate device, simplify installation and maintenance operations, and improve the scalability of the gate device.
In the embodiment, the adaptation of the infrared transceiving modules 30 of different models and different manufacturers can be completed through the bus protocol design, and the infrared transceiving modules 30 of different models or different manufacturers can be compatible only by the infrared transceiving modules 30 compatible with the address learning circuit and the protocol logic, so that the later maintenance and the equipment hardware upgrade are facilitated; in addition, the infrared transceiver module 30 can be mounted on the transceiver bus 20, so that the design of the infrared adapter plate can be reduced, and the internal space of the gate device can be saved.
Optionally, the infrared transceiver module 30 of this embodiment is provided with a second I/O port b, a pull-down resistor R2 and a first detection circuit 31, one end of the pull-down resistor R2 is connected to the second I/O port b, the other end of the pull-down resistor R2 is connected to the first detection circuit 31, and the other end of the voltage-dividing resistor R1 is connected to the other end of the pull-down resistor R2; when the second I/O port b is pulled down to ground, the first detection circuit 31 obtains a voltage division value of the pull-down resistor R2 for the voltage signal, and generates address information of the infrared transceiver module 30 according to the voltage division value.
In this embodiment, at least two voltage dividing resistors R1 are serially connected to the transceiving bus 20, one end of the first voltage dividing resistor R1 is connected to the first I/O port a of the main control module 10 through the transceiving bus 30, and the other end of the pull-down resistor R2 in each infrared transceiving module 30 is connected to one end of the corresponding voltage dividing resistor R1, which is far away from the first I/O port a of the main control module 10, so that the voltage dividing resistor R1 and the pull-down resistor R2 form a conductive path.
When the second I/O port b of the infrared transceiver module 30 is pulled down to ground, the pull-down resistor R2 and the voltage dividing resistor R1 are connected in series to form a conductive path, and the voltage dividing value of the pull-down resistor R2 on the voltage signal can be obtained through the first detection circuit 31. The second I/O port b of each infrared transceiver module 30 may be sequentially pulled down to ground, and the corresponding first detection circuit 31 may obtain a voltage division value of the pull-down resistor R2 on the voltage signal on the transceiver bus 30, so as to obtain address information of each infrared transceiver module 30.
Optionally, a collision avoidance strategy is adopted to pull down the second I/O port b of each infrared transceiver module 30 to ground in sequence.
Specifically, the infrared transceiver modules 30 generate a random number of 1-100 by the true random number generator, each infrared transceiver module 30 determines an address information reporting time slot by the true random number, the infrared transceiver modules 30 determine whether the transceiver bus 20 is idle (described in detail below) by monitoring the voltage state of the transceiver bus 20 (by the second detection circuit 11) before reporting, and when the transceiver bus 20 is not idle, that is, when other infrared transceiver modules 30 operate the transceiver bus 20, the infrared transceiver modules 30 continue to wait for the next reporting time slot on the basis of the random number until the transceiver bus 20 is idle, and report the address information.
The first detection circuit 31 may include an Analog-to-Digital Converter (ADC). The ADC is used for converting the acquired voltage division value in an analog form into a voltage division value in a digital form.
The first detection circuit 31 further converts the divided voltage value outputted from the ADC into corresponding address information (horizontal axis coordinate value in fig. 2) by using the relation curve S1 shown in fig. 2.
Optionally, the infrared transceiver module 30 of this embodiment further includes an encoding circuit 32, which is respectively connected to the first detection circuit 31 and the first I/O port a, and the encoding circuit 32 is configured to encode the address information acquired by the first detection circuit 31, so as to implement infrared encoding transceiving of the infrared transceiver module 30.
As can be seen from the above analysis, the infrared transceiving module 30 can automatically allocate unique address information, so that the infrared signal can be encoded by using the address information and decoded by using the address information, if the decoding is successful, the infrared transmission and the infrared reception of the infrared transceiving module 30 are considered to be matched, and if the decoding is failed, the infrared transmission and the infrared reception are considered to be unmatched; in this way, the signal interference of other infrared transceiver modules 30 to the infrared transceiver module 30 can be filtered out.
Optionally, the gate device of this embodiment further includes: and one end of the pull-up resistor R is connected to the power supply voltage VCC, and the other end of the pull-up resistor R is connected to the first I/O port a of the main control module 10 and is used for generating a voltage signal under the control of the control signal of the main control module 10.
It should be noted that, in order to simplify the calculation, only the second I/O port b of one of the plurality of ir transceiving modules 30 is pulled down to ground at a time, and since the number of pull-down resistors R2 serially connected in the above-mentioned conductive path formed by each ir transceiving module 30 is different, the voltage division signals of the pull-down resistor R2 for the voltage signal in each ir transceiving module 30 are different, and therefore each ir transceiving module 30 can be guaranteed to have unique address information.
When the second I/O port b is grounded through a pull-down resistor R, a voltage dividing resistor R1, and a pull-down resistor R2, the power supply voltage VCC is grounded through the pull-up resistor R, the voltage dividing resistor R1, and the pull-down resistor R2, so that the first detection circuit 31 in the infrared transceiver module 30 can obtain the voltage Vn at the end of the pull-down resistor R2 close to the voltage dividing resistor R1, and according to the voltage dividing rule, when only one second I/O port b of one infrared transceiver module 30 is grounded through a pull-down, the address of the infrared transceiver module 30 on the transceiver bus 20 can be identified according to different voltage dividing signals (voltage dividing values). The address calculation formula is as follows:
where Vn is the voltage division value of the pull-down resistor R2.
When the gate device of this embodiment is powered on for the first time, the main control module 10 sends an address learning instruction to the infrared transceiver module 30 to start the address learning function of the infrared transceiver module 30 (i.e., automatically generate address information); after the address learning is completed, the gate device is turned on and the corresponding infrared transceiver module 30 can be started only by the address query command.
Optionally, the main control module 10 of this embodiment includes a second detection circuit 11, connected to one end of the transceiving bus 20 connected to the first I/O port a, for detecting a voltage on the transceiving bus 20.
The second detection circuit 11 may include an Analog-to-Digital Converter (ADC). The ADC is used to convert the voltage on the transmit receive bus 20 in analog form collected into a voltage in digital form.
The second detection circuit 11 further converts the voltage on the transmission/reception bus 20 into corresponding address information (horizontal axis coordinate value in fig. 2) by using the relation curve S2 as shown in fig. 2.
Optionally, the main control module 10 of this embodiment further includes a main control circuit 12, which is respectively connected to the second detection circuit 11 and the first I/O port a, and is not only used for providing a control signal to the first I/O port a, but also used for processing the voltage on the transceiving bus 20 acquired by the second detection circuit 11 and performing other control of the gate device.
The main control circuit 12 determines whether the voltage on the transceiving bus 20 detected by the second detection circuit 11 is a high level signal, if so, the main control circuit 10 determines that the transceiving bus 20 is in an idle state, and the main control circuit 12 outputs a control instruction to the first I/O port a; the control instruction is a low level signal with preset duration, and the preset durations corresponding to different control instructions are different. The control instruction comprises an address learning instruction, an address inquiry instruction, an infrared scanning instruction and the like.
The main control circuit 12 can send an address signal query instruction to the corresponding infrared transceiver module 30 according to the obtained address information.
As can be seen from the above analysis, when only the second I/O ports b of 1 ir transceiving module 30 are pulled down to ground at the same time, the ir transceiving module 30 can determine its own address information through the first detection circuit 31; at this time, the main control module 10 can also obtain the address information of the infrared transceiving module 30 through the second detection circuit 11. According to the design, the address learning of the infrared transceiving module 30 and the bus communication between the infrared transceiving module 30 and the main control module 10 can be realized.
In this embodiment, the number of the infrared transceiver modules 30 is 4, that is, n is 4, the power supply voltage VCC may be 5V, the resistance of the pull-up resistor R may be 4.2K Ω, the resistance of the voltage dividing resistor R1 may be 1K Ω, the resistance of the pull-down resistor R2 may be 4.2K Ω, the calculated divided voltage values corresponding to the 4 infrared transceiver modules 30 are shown by a curve S1 in fig. 2, and the calculated voltages of the corresponding 4 transceiver buses obtained by the second detection circuit 11 are shown by a curve S2 in fig. 2.
In other embodiments, the number of the infrared transceiver modules and the resistance of each resistor can be adjusted as required.
In an application scenario, the present embodiment may monitor whether the voltage of the transceiving bus 20 is 5V to determine whether the transceiving bus 20 is idle. When the transceiving bus 20 is idle, that is, when neither the first I/O port a of the main control module 10 nor the second I/O port b of the infrared transceiving module 30 is pulled down, the voltage of the transceiving bus 20 is 5V; when the first I/O port a of the main control module 10 pulls down the transceiving bus 20 (may output a low level voltage to the transceiving bus 20), the voltage of the transceiving bus 20 is 0, which is a low level, and the infrared transceiving module 30 on the transceiving bus 20 may measure the duration of the low level on the transceiving bus 20 through the first detection circuit 31 to obtain the instruction issued by the main control module 10; when a second I/O port b of one infrared transceiver module 30 is pulled down, the main control module 10 will monitor the voltage change on the transceiver bus 20 through the second detection circuit 11; in the non-instruction sending state, the main control module 10 monitors the level state of the transceiving bus 20 to determine that the infrared transceiving module 30 responds, and when the main control module 10 is in the address learning state, the main control module 10 monitors the voltage of the transceiving bus 20 through the second detection circuit 11 to determine that the address of each infrared transceiving module 30 exists, and in the address reporting stage, the infrared transceiving module 30 performs self-detection to determine the position of the infrared transceiving module 30 which has a fault. When the infrared scanning stage is performed, the main control module 10 determines the infrared shielding state of the infrared transceiving module 30 by monitoring the voltage of the transceiving bus 20 through the second detection circuit 11.
The present application further proposes another embodiment of a gate device, as shown in fig. 3, fig. 3 is a schematic structural diagram of an embodiment of the gate device of the present application. The main control module 10 of the gate device (not shown) of this embodiment has two first I/O ports a, the infrared transceiver module 30 includes an infrared transmitter module 33 and an infrared receiver module 34, the transceiver bus 20 includes a transmitter bus 21 and a receiver bus 22, the infrared transmitter module 33 has a second I/O port b, a pull-down resistor R2 and a detection circuit 31, the infrared receiver module 33 has another second I/O port b, the emission bus 21 is connected in series with at least two divider resistors R1, the reception bus 22 is connected in series with at least two other divider resistors R1, one of the two first I/O ports a is connected with one end of the divider resistor R1 corresponding to the infrared emission module 33 through the emission bus 21, and the other of the two first I/O ports a is connected with one end of the divider resistor R1 corresponding to the infrared reception module 34 through the reception bus 22; the gate device in this embodiment includes two pull-up resistors R, the main control module 10 includes two second detection circuits 11, one end of each pull-up resistor R is connected to the supply voltage VCC, and the other end of each pull-up resistor R is connected to the two second detection circuits 11 in a one-to-one correspondence manner.
The main control module 10 of this embodiment is connected to at least two infrared transmitting modules 33 through a transmitting bus 21, and connected to at least two infrared receiving modules 34 through a receiving bus 22, so as to form an infrared transmitting branch and an infrared receiving branch, where the circuit structures and the operating principles of the infrared transmitting branch and the infrared receiving branch are similar, and reference may be made to the above embodiments, which are not repeated herein.
The infrared transmitting module 33 and the corresponding infrared receiving module 34 can be matched through address information; the infrared transmitting module 33 and the corresponding infrared receiving module 34 can communicate by infrared code signals.
Specifically, the infrared transmitting module 33 and the infrared receiving module 34 determine their own address information through address learning; the infrared transmitting module 33 performs infrared encoding on the address information and transmits the address information, and the infrared receiving module 34 with the same address information decodes the infrared information and compares the addresses, and if the address information is the same, the communication is successful, and if the address information is different or the receiving time is overtime, the infrared receiving is abnormal. When the infrared receiving is abnormal, the infrared receiving module 34 may preset a time duration by pulling down the corresponding second I/O port b to report the abnormality, and the second detection circuit 11 of the main control module 10 may determine the abnormal position by monitoring the voltage change and the time duration on the receiving bus 22.
The infrared transmitting module 33 and the infrared receiving module 34 can pull down the corresponding bus voltage through the corresponding first I/O port a when the computer is started, so as to determine the unique address information of the computer in the bus, and implement power-down storage to reduce the starting time after subsequent startup; the infrared receiving module 34 can normally receive the infrared signal generated by the infrared transmitting module 33 with the matched address information and can filter the non-matched infrared signal. When the gate equipment is started, the position of the infrared transceiving module 30 with a fault can be determined according to the address learning state, the infrared transceiving module 30 determines whether the infrared transmitting module 33 or the infrared receiving module 34 with the fault is adopted, and then the corresponding replacement and electrification are carried out; the number of the infrared transceiving modules 30 can be freely increased or decreased according to product requirements, and the infrared transceiving modules are only required to be mounted on or pulled out of the corresponding buses, do not need to be additionally configured, and are convenient to maintain and expand.
The embodiment uses an infrared coding mechanism and an address matching mechanism, realizes address matching of the infrared transmitting module 33 and the infrared receiving module 34 at the same position, effectively improves the infrared anti-interference capability of the gate equipment, solves the alignment problem of the infrared transmitting module 33 and the infrared receiving module 34, and reduces the requirement of the gate equipment on the installation precision.
From the above analysis, after the first power-on address learning is completed, the infrared transceiver module 30 can be started only by the address query instruction when the subsequent gate device is started; if the infrared transceiver module 30 is detected normally, it is not necessary to perform address learning again, and the process supports monitoring the on-line status of the infrared transceiver module 30 and detecting an abnormal infrared transceiver module 30, and the initialization process is shown in fig. 4. After the gate device completes power-on initialization, the infrared transmitting module 33 and the infrared receiving module 34 complete address matching; the matched infrared receiving module 33 can distinguish whether the infrared signal comes from the paired infrared transmitting module 32, thereby completing the filtering of the infrared interference signal.
Specifically, as shown in fig. 4, after the gate is powered on, the main control module 10 sends an address query instruction to the infrared transceiver modules 30, and if all the infrared transceiver modules 30 respond, it determines whether the sequence of the detected address information is continuous; if not all the infrared transceiving modules 30 completely respond or the sequence of the detected address information is discontinuous, judging whether the number of address learning times is greater than the preset number of times, such as 3 times; if the address learning times are less than or equal to the preset times, performing address learning, and sending an address query instruction to the infrared transceiving module 30, if the address learning times are greater than the preset times, determining that the self-checking fails, and ending the control; if the sequence of the detected address information is continuous, controlling the infrared transceiving module 30 to perform infrared scanning and judging whether infrared is not blocked; if the shielding does not exist, judging that the self-checking is passed, and finishing the control; if the shielding exists, giving an alarm to prompt that the channel exits, and continuously presetting the time length, and if the channel does not exist, judging whether the channel exists or not in 10 s; if the shielding exists, the self-checking is judged to fail, the control is finished, and if the shielding does not exist, the infrared scanning is continued.
Different from the prior art, the infrared transceiver module is characterized in that a divider resistor is connected in series on the transceiver bus, the infrared transceiver module is connected with the divider resistor, and the address information of the infrared transceiver module is automatically generated by using the voltage at the other end of the divider resistor; therefore, the address allocation and identification of the infrared transceiving module on the transceiving bus can be realized through the bus voltage division mechanism, and compared with the scheme of performing address allocation and identification in a mode of using a dial switch or expanding an I/O port in the prior art, the address allocation and identification method can simplify the hardware structure of the gate equipment, simplify the installation and maintenance operation and improve the expandability of the gate equipment.
Furthermore, the address learning mode is used, so that the gate equipment can be adapted to infrared receiving and transmitting modules (an infrared receiving module and an infrared transmitting module) which conform to the same protocol and are of different models or different manufacturers, the number of the infrared receiving and transmitting modules can be freely increased or decreased, and the compatibility and the universality of the system are improved; through address matching of the infrared transceiving module, the infrared transceiving module filters received infrared signals through address information, the infrared anti-interference capability is improved, and the alignment requirement of the infrared transceiving module is reduced; the address information of the problem infrared receiving and transmitting module is judged through an address query mechanism in the power-on initialization process of the gate equipment, and the power-on self-test of the gate equipment is realized.
