The first network interface unit 141 transmits the number of parking spaces 31 in each road area 3 from each area server 13 through the communication network 5 and each area device, and the number of new remaining parking spaces 31 enters the road area 3 The number of vehicles inside 2! The vehicle identification information is then temporarily stored in the storage unit 142. In this example, the hidden portion 142# takes a rewritable memory as an example, and stores a re-reading discriminating program. The control unit 143 corrects the above-mentioned various kinds of information according to the corresponding road area 3, and under the execution of the above-described repeated reading determination program, the control unit 143 determines whether or not there is a different area server 13 repeatedly receiving the same vehicle identification, two ? Shape, right to determine this situation' can be deducted according to the preset rule, for example, the preset rule can be the first to receive the vehicle identification: the road area 3, and then receive the same vehicle The road area 3' of the identification information is added to the number of remaining parking spaces 31, respectively, and the number of vehicles 2 entering the road area 3 is reduced by one. 200844917 After the above determination and correction procedure, the control unit 143 transmits the number of parking spaces 31 in each road area 3, the number of newly remaining parking spaces 31, and the number of vehicle auxiliary 2 entering the road area 3 through the second network interface unit 144. And - the communication network 6 is transmitted to the digital broadcasting station 15. In this example, Tongjian Road 6 is also a wired Internet, but not limited to this. The digital broadcast station 15 receives the above-mentioned various amounts of information from the central server 14 and, after appropriate processing, digitally broadcasts the digits of the digital broadcast. ^ ^ In this example, the broadcast receiver 16 is portable for the driver of the vehicle to carry around, but not limited to this. The broadcast receiver 16 receives the quantity information from the digital broadcasting station 15 and directly plays it on a display screen (not shown) in a text format. For other financial purposes, the broadcast receiver 16 can be combined with the existing navigation function: the electronic map of each of the road areas 43 is built therein, and the number of parking spaces 31 and the latest remaining parking spaces 31 in each road domain 3 can be set. The number of vehicles 2 entering the road area 3 is displayed on the corresponding electronic map for the driver's reference. As shown in the flowchart of FIG. 5, in accordance with the above system, the present invention also discloses a digital broadcast parking information providing method combining radio frequency identification technology. The main implementation steps of the preferred embodiment are as follows: The reader 12 in the road area 3 continues to issue the interrogation signal; as shown in steps 902, 903, when the vehicle 2 enters the road area 3 & /, the attached radio frequency identification tag 11 will receive the reader 12 After the verification of the probe signal, the built-in vehicle identification information is transmitted to respond to 12 200844917 to the reader 12; as shown in step 904, after the reader 12 receives the vehicle identification information from each vehicle 2, the vehicle is The identification information is transmitted to the area server u; as shown in step 905, after receiving the vehicle identification information from each reader a, the area server 13 determines whether the same vehicle identification information is received twice or more before a predetermined time; In step 906, if the determination result exceeds the preset time, the vehicle 2 corresponding to the vehicle identification information is regarded as having stopped the parking space 31 in the road area 3, and will be stored in advance. The number of all parking spaces in the road area 3 is deducted by one to obtain the actual number of remaining parking spaces 31 in the road area 3 as shown in step 907, and vice versa.
