[0029] A multifunctional barrier gate, comprising any of the above-mentioned multifunctional barrier gate drive circuits with anti-power-off function.

[0030] Compared with the prior art, the present invention has the following beneficial effects: the present invention provides a multifunctional barrier gate drive circuit that can prevent power failure, and the multifunctional barrier gate drive circuit that can prevent power failure includes a main control module, a drive module, a dial module and an output module. The main control module can output a first control signal and a second control signal, the drive module can generate a first drive signal based on the first control signal, and the drive module can generate a second drive signal based on the second control signal. The first drive signal can drive the barrier gate to perform a gate-lifting operation, and the second drive signal can drive the barrier gate to perform a gate-lowering operation. The dial signal can call the parameters of the main control module to adjust the output time of the second control signal. If the barrier gate is abnormally lifted, the main control module outputs the second control signal after the time set by the abnormal gate lift based on the dial signal. Therefore, after the barrier gate is abnormally lifted, the main control module controls the barrier gate to perform a gate-lowering operation based on the dial signal. If a toll parking lot is installed with a barrier gate with the circuit, losses caused by abnormal gate lift can be effectively avoided. Even if the barrier gate is abnormally lifted, the multifunctional barrier gate drive circuit can recover automatically. The gate with this circuit can maintain normal working state, and the user does not need to inspect and repair the gate. Therefore, in the case of abnormal gate lifting, the gate with this circuit can also meet the user's usage needs.

[0031] When the parking lot environment becomes dark, the main control module can output a first LED lamp driving signal, and the first LED lamp driving signal is used to drive the white light LED lamp to light up. Because the main control module can drive the white light LED lamp to emit light, the gate of this circuit can effectively avoid the problem that the gate pole is easily broken in a dim environment or at night. Therefore, the gate with this circuit can meet the needs of users in dim environments or at night. Moreover, the main control module can output a second LED lamp driving signal. The second LED lamp driving signal can drive a red light LED lamp or a green light LED lamp, and the red light LED lamp and the green light LED lamp are used to prompt whether there is a car in the turning vehicle channel. Thereby, it can be helpful to divert traffic in the parking lot and effectively avoid the problem of easy traffic congestion in the parking lot. The gate with this circuit is set with multiple functions, which effectively solves the technical problem that the existing gate has a relatively single function. Therefore, the gate with this circuit can match the diverse needs of users.

[0032] In addition, the anti-power-off multifunctional gate driving circuit also includes a main power supply, a backup power supply, a voltage sampling module, a step-down module, a step-up module, and a voltage conversion module. The main power supply can output a first voltage, and the backup power supply can output a second voltage. The voltage sampling module can perform a voltage division operation on the first voltage, and the voltage sampling module can generate a sampled voltage. The main control module can compare the voltage value of the sampled voltage with the set value. If the voltage value of the sampled voltage is greater than the set value, the main control module outputs a control signal. When the step-down module does not receive the control signal, the step-down module performs a step-down operation on the first voltage, and the step-down module can generate a third voltage. When the step-down module receives the control signal, the step-down module performs a step-down operation on the second voltage, and the step-down module can generate a fourth voltage. The step-up module can perform a step-up operation on the third voltage or the fourth voltage, and the step-up module can generate a first supply voltage, which is used to power the driving module. The voltage conversion module can perform a voltage conversion operation on the third voltage or the fourth voltage, and the voltage conversion module can generate a second supply voltage, which is used to power the main control module. Therefore, in the event of an abnormal power outage, the multifunctional barrier drive circuit can also convert the second voltage output by the backup power supply into the first power supply voltage and the second power supply voltage, thereby maintaining the power supply to the barrier. This effectively solves the technical problem that the existing barrier cannot work in the event of an abnormal power outage. If a toll parking lot is equipped with a barrier with this circuit, it can effectively avoid losses caused by abnormal power outages. In addition, the barrier can also maintain a stable working state for a long time without sudden power outages. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the anti-power-off multifunctional barrier drive circuit 10 can expand the output to the function of driving an inductive load such as a clutch and an electric lock.

[0083] The working principle of the present invention is as follows: when the parking lot is powered normally, the gate can work normally, and at this time, the main power supply 11 can output a first voltage. The voltage sampling module 13 can perform a voltage division operation on the first voltage, and the voltage sampling module 13 can generate a sampling voltage. The main control module 14 can compare the voltage value of the sampling voltage with the set value. If the voltage value of the sampling voltage is greater than the set value, the main control module 14 outputs a control signal. When the step-down module 15 receives the control signal, the step-down module 15 performs a step-down operation on the first voltage, and the step-down module 15 can generate a third voltage. The boost module 16 can perform a step-up operation on the third voltage, and the boost module 16 generates a first supply voltage, and the first supply voltage is used to power the driving module 18. The voltage conversion module 17 can perform a voltage conversion operation on the third voltage, and the voltage conversion module 17 can generate a second supply voltage, and the second supply voltage is used to power the main control module 14.

[0084] When the vehicle approaches the barrier, the main control module 14 may output a first control signal, the driving module 13 may generate a first driving signal based on the first control signal, and the first driving signal may drive the barrier to perform a gate-lifting operation. When the vehicle is away from the barrier, the main control module 14 may output a second control signal, the driving module 13 may generate a second driving signal based on the second control signal, and the second driving signal may drive the barrier to perform a gate-lowering operation. The multifunctional barrier driving circuit 10 is provided with a dialing module 141, and the dialing module 141 may output a dialing signal. When the barrier is abnormally lifted, the main control module 14 outputs a second control signal based on the dialing signal after the time set for the abnormal gate lifting, so that the second driving signal may drive the barrier to perform a gate-lowering operation. Therefore, even if the barrier is abnormally lifted, the multifunctional barrier driving circuit 10 may recover by itself. Furthermore, the barrier with the circuit may maintain a normal working state, and the user does not need to overhaul the barrier. When the parking environment becomes dark, the main control module 12 may output a first LED lamp driving signal, and the first LED lamp driving signal may drive the white light LED lamp to light up. In addition, the main control module 14 can also output a second LED light driving signal. Even in a dim environment, the gate with the circuit can be used normally. The second LED light driving signal can drive a red LED light or a green LED light, and the red LED light and the green LED light can indicate whether there is a vehicle in the turning vehicle channel. The multifunctional gate driving circuit 10 can guide the traffic in the parking lot through the red LED light and the green LED light, avoiding the problem of easy traffic congestion in the parking lot.

[0085] When the parking lot has an abnormal power outage, the backup power supply 12 can output a second voltage. The main power supply 11 does not output the first voltage, so the voltage sampling module 13 does not generate a sampling voltage. Therefore, if the voltage value of the sampling voltage is less than the set value, the main control module 14 does not output a control signal. When the step-down module 15 does not receive the control signal, the step-down module 15 performs a step-down operation on the second voltage, and the step-down module 15 can generate a fourth voltage. The boost module 16 can perform a step-up operation on the fourth voltage, and the boost module 16 generates a first supply voltage, and the first supply voltage is used to power the drive module 18. The voltage conversion module 17 can perform a voltage conversion operation on the fourth voltage, and the voltage conversion module 17 can generate a second supply voltage, and the second supply voltage is used to power the main control module 14.

[0086] In summary, although the present invention has been disclosed as above in terms of preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention.
