Therefore, in the case of abnormal lifting barrier, the barrier with the circuit can also meet the use demand of user.
[0054] When the environment of the parking lot is dark, the master control module can output a first LED lamp driving signal, which is used to drive the white light LED lamp to light up. Because the master control module can drive the white light LED lamp to emit light, the barrier gate with the circuit can effectively avoid the problem that the barrier rod is easily broken in a dim environment or at night. Therefore, the barrier gate with the circuit can meet the needs of users in a dim environment or at night. Moreover, the master 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, which are used to prompt whether there is a vehicle in the turning vehicle channel. Thus, it is beneficial to guide the traffic in the parking lot, and effectively avoids the problem that the parking lot is prone to traffic congestion. The barrier gate with the circuit is provided with multiple functions, and effectively solves the technical problem that the existing barrier gate has a single function. Therefore, the barrier gate with the circuit can match the diverse needs of users.
[0055] In summary, although the utility model has disclosed as above with preferred embodiments, the above preferred embodiments are not used to limit the utility model, the ordinary skilled in the art can make various changes and decorations without departing from the spirit and scope of the utility model, therefore the protection scope of the utility model is the range defined by claims.
