Hereinafter, a wireless remote control for driving record of the present invention will be described in detail with reference to the accompanying drawings.

The present invention is a wireless remote control for vehicle driving record, which is designed to be suitable for the characteristics of the vehicle driving record data transmission, which is an improvement of the wireless communication method, which requires a lot of communication time and does not have good radio wave efficiency by being performed by the conventional two-way transmission and reception.

The wireless remote control for vehicle driving record of the present invention is, first, conventional 1: many communication is possible only in a general communication program, but in the present invention, the communication time can be reduced because the characteristics of the radio wave are maximized, not the communication program. By using this same radio wave, it can be effectively used. Second, the data transfer is accurate because there is no error by determining the transmission order of the vehicle by the sequential random number generation method in the control unit (CPU) included in the transmitting unit of the transmitting apparatus without depending on a complicated communication program. Third, unlike the conventional vehicle operation data device includes both a transceiver and a vehicle according to the present invention, the transmission unit is installed and the receiver is installed at a remote location, thereby reducing the manufacturing cost.

1A is a block diagram showing a communication state between a vehicle equipped with a wireless remote controller of the present invention and a vehicle driving record receiving base station (usually installed in an office of a transportation company). As shown, the transmitters A-0, A-1, A-2, B-0, B-1, of the wireless remote control apparatus, which are used to transmit vehicle driving record data, although not shown in individual vehicles. And the like, and the transmitting apparatus is a device which transmits and transmits vehicle driving record data unilaterally without being transmitted / received with the vehicle driving record receiving base station apparatus. The transmitter is connected to a tachometer of a bus or a meter of a taxi to transmit various types of driving data.

According to the present invention, a computer and a display unit are connected to the receiving apparatuses A-M, B-M, C-M, .. of the base station. The computer 45 (in FIG. 4) is used to process and process data in a required form, and can generate data in a required file. In addition, the display unit may display driving data directly to the driver using a monitor of a PC or using a display means such as an electronic sign.

2 and 4 are schematic structural diagrams of a receiver and a transmitter of the present invention as described above. First, the transmission device mounted on a vehicle for transmitting the tachometer data includes an interface unit 22 for transmitting data of the tachometer control unit 21 that stores and processes the vehicle operation data generated from the tachometer 20 in accordance with a standard. And a transmitter 23 for transmitting data transmitted from the interface unit 22, and a receiver 24 for identifying a radio transmission / reception state from another vehicle and controlling a radio transmission state of the transmitter 23. do.

The tachometer 20 is a device for recording the driving state of the vehicle as known, and detects various driving record data such as driving time, stop time, driving speed and transmits it to the tachometer controller 21. The tachometer controller 21 sequentially stores the transmitted data in a memory device installed therein. In this state, the vehicle driving state is stored in the tachometer control unit 21, and the vehicle returns to the company for shifting the vehicle at a predetermined time. After returning to the company, a control signal is inputted to transmit driving data by the vehicle driver or assistant. According to the present invention, it is also possible to input a timer function to automatically transmit vehicle driving data at the time when the vehicle shift time, for example, 3-4 pm is the vehicle shift time instead of the input of the control signal by the driver or assistant. It will be apparent to those skilled in the art.

When the transfer request of the vehicle driving record data is input, the controller 21 transmits the stored data to the transmitter 23 through the interface unit 22. The transmitted data is temporarily stored in the transmitter 23. At the same time, the transmitter 23 transmits a communication status signal between radio stations from the receiver 24 connected thereto to confirm whether communication between the receiver for current driving record data (installed in the office as a base station of the vehicle) and other vehicles is being performed. Get input. The receiver 24 may be configured to detect that the communication between the other vehicle and the base station is being performed when the signal strength, that is, the electric field strength, is 2 μV or more.

If communication with another vehicle is being performed, the transmission signal from the other vehicle is received by the receiver 24, so that the transmission data from the tachometer controller 21 is not transmitted wirelessly and is in a standby state. This can be achieved by a control unit (microcomputer) provided in the transmission unit 23.

When the other vehicle and the base station receiver are in communication, the transmitter which attempted the communication generates a random number after 10 ms for data transmission. The random number is a means for distinguishing a signal between the present vehicle and another vehicle, and the transmission apparatus of the vehicle which attempts to transmit by the random number generation is sequentially given a transmission time after confirming its ID. This makes it possible to communicate very effectively when multiple vehicles are mixed and attempting to communicate. This is illustrated well in the flowchart of FIG. 3. Random number generation is performed by a program stored in the microcomputer (CPU).

After that, the transmitter 23 detects the communication state again and maintains the standby state when the communication state is detected. Otherwise, random number generation is started, data is output, and the driving record data is transmitted to the receiving apparatus located in the base station. The random number generation is generated from all of the plurality of vehicles, but since the random number generation state is set in advance so as not to be the same, the ID of each vehicle is not confused. That is, it is set to the order of stopping wearing or the order of turning off the engine first after stopping.

In addition, referring to Figure 4, the receiving device of the present invention, the receiving unit 40 for receiving a signal transmitted from the transmitting device, the interface unit 41 for transmitting the signal from the receiving unit 40 in accordance with the standard and And a main controller 42 for receiving and processing a signal from the interface unit 41, a display unit 43 for displaying a signal output from the main controller 42, and an output from the main controller 42. It consists of a data output section 44 for printing the data.

As described above, when the vehicle driving record data is input from the vehicle transmission apparatus, it is received by the receiver 40 and then inputted to the controller 42 while being processed through the interface 41. At this time, since the driving record data inputted are all distinguished by random number generation as described above, there is no fear of confusion in the main control unit 43. 5 is a flowchart showing an operating state of a receiving apparatus.

6, 7, and 8 are detailed circuit diagrams of the transmission apparatus of the present invention, respectively. FIG. 6 shows a scheme using a PLL circuit and FIG. 8 shows a configuration using X-tal. Its operating state is as follows.

First, referring to FIG. 6, the circuit block 63 checks a communication state of another vehicle from the circuit block 62A for detecting a field strength of 2 μV as a circuit for checking a reception state. 7 also checks the reception state at the microcomputer CPU2 of the circuit block 72 and starts random number generation. 8 is a control unit of the transmitter of the present invention, which checks the reception state at the microcomputer CPU2A of the circuit block 84 and generates a random number when communication with another vehicle is detected.

If the communication state with the other vehicle is not detected, the transmission unit 23 of the transmitting device wirelessly transmits the vehicle driving record data stored in the tachometer control unit 21. At this time, the wireless data transmitted is inserted into the front and rear ends of the signal and the initial password and the cipher read signal generated by the random number generation for vehicle identification. The vehicle driving record data received by the receiver 40 may be temporarily stored in the main controller 42 and visually displayed by the display unit 43. In addition, it can be stored in the PC 45 as a data file to be used later for data processing, and the result can be output through the data output unit 44.

As described above, according to the present invention, since a plurality of communication can be performed without a special communication program, the communication time can be reduced and the radio waves can be efficiently used. In addition, by generating a sequential random number at the time of data transmission has the advantage of performing the correct data transmission by specifying the rank of the wireless communication. Moreover, since only one transmitting unit is required on one side and only the receiving unit on the other side, manufacturing costs are reduced, and an installation method and a use method are also easy and convenient.

Although the invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that modifications and variations can be made within the spirit and scope of the invention, and such variations or modifications will belong to the appended claims. .
