Further, also comprise: wireless communication module; Described processor is connected with the wave point of described host computer by described wireless communication module.
Further, described crystal oscillator chip is passive crystal oscillator.
Further, the antenna of described antenna-feedback system is the right-handed circular polarization antenna.
The beneficial effects of the utility model are:
The parking lot read write line that is applicable to the ETC electronic tag that the utility model provides can reduce the use cost of vehicle on the one hand.On the other hand, because the ETC electronic tag has uniqueness, so the application by the parking lot read write line that is applicable to the ETC electronic tag that the utility model is provided has not only realized the effective management to the parking lot, thereby stopped the generation of the phenomenon of parking lot management confusion, and safe.The utility model is rational in infrastructure, and effect is remarkable, and is practical.
Description of drawings
The structured flowchart of the parking lot read write line that is applicable to the ETC electronic tag that Fig. 1 provides for the utility model embodiment.
The structured flowchart of radio circuit in the parking lot read write line that is applicable to the ETC electronic tag that Fig. 2 provides for the utility model embodiment.
Embodiment
For the further the utility model of setting forth is to reach technological means and the effect that predetermined utility model purpose is taked, below in conjunction with accompanying drawing and preferred embodiment, embodiment and principle of work according to the parking lot read write line that is applicable to the ETC electronic tag that the utility model proposes are elaborated.
As shown in Figure 1, the parking lot read write line that is applicable to the ETC electronic tag that the utility model provides comprises: processor, 24V1A power module, radio circuit, wireless communication module, antenna-feedback system and relay; Processor is connected with 3V output terminal, radio circuit and the relay of 24V1A power module respectively; Processor also is connected with the wave point of host computer by wireless communication module, is embedded in the automobile door control system at host computer.The 5V output terminal of 24V1A power module is connected with radio circuit, and radio circuit also is connected with antenna-feedback system; Relay also is connected with banister.
As shown in Figure 2, radio circuit comprises: PA chip, radio frequency chip and crystal oscillator chip; Radio frequency chip is connected with the 5V output terminal of processor, crystal oscillator chip, 24V1A power module and the receiving antenna of antenna-feedback system respectively; Radio frequency chip also is connected with the emitting antenna of antenna-feedback system by the PA chip.
Preferably, in the present embodiment, the crystal oscillator chip is passive crystal oscillator, and the receiving antenna of antenna-feedback system and emitting antenna are the right-handed circular polarization antenna.
The use prerequisite of the parking lot read write line that is applicable to the ETC electronic tag that the utility model provides is the ETC electronic tag to be housed at each automobile through the parking lot banister, and comprises the information such as MAC Address, vehicle and license plate number at the ETC electronic tag.
The parking lot read write line that is applicable to the ETC electronic tag that the utility model provides is when work, at first by the 24V1A power module alternating current of access is converted to the direct current of 24V, and the direct current that the direct current of 24V converts 5V to outputed to radio circuit, the direct current that also direct current of 24V is converted simultaneously to 3V outputs to processor.When vehicle arrives the banister place, at first by emitting antenna the signal of 5.8GHz is sent to the ETC electronic tag of automobile by antenna-feedback system, and receive the signal of the 5.8GHz that is responded by the ETC electronic tag by the receiving antenna of antenna-feedback system.By radio circuit the response signal that antenna-feedback system receives is carried out the processing of power amplification, voltage stabilization and current stabilization again, the signal after then will processing sends in the processor; Processor intercepts out MAC Address data, model data and license number data again from the signal that receives, and with the data transmission that intercepts out to host computer.Automobile door control system in the host computer according to the data that receive judge the vehicle that has this ETC electronic tag whether be authorized to by.Can pass through the lock road if judge the vehicle that has this ETC electronic tag, then host computer will be opened a sluice gate command to processor, and processor will be opened a sluice gate command again to relay, and relay receives the order closure, thereby banister is risen; Can not pass through the lock road if judge the vehicle that has this ETC electronic tag, then host computer will not opened a sluice gate instruction is transferred to vehicle by the emitting antenna of antenna-feedback system ETC electronic tag.
Because the ETC electronic tag has uniqueness, so application by the parking lot read write line that is applicable to the ETC electronic tag that the utility model is provided, on vehicle, only need to install the ETC electronic tag, and just be used with the parking lot read write line that is applicable to the ETC electronic tag that the utility model provides and can pass through the parking lot banister, so just reduced the expense of read write line had been installed at vehicle originally, thereby reduced the use cost of vehicle.Simultaneously, also realize the effective management to the parking lot, thereby stopped the generation of the phenomenon of parking lot management confusion, and safe.In addition, the automobile door control system of the parking lot read write line that is applicable to the ETC electronic tag that provides based on the utility model can store vehicles while passing and location information into database, thereby can realize the trajectory analysis to the vehicle that the ETC electronic tag is installed, such as flow analysis and jam situation analysis.The utility model is rational in infrastructure, and effect is remarkable, and is practical.
