It is an invention to be made.

  For taxis, tourist buses, and long-distance trucks that drive throughout the day and night, it is extremely important to prevent car accidents, and there should be no drunk driving or drunk driving. For this reason, the operation manager is subject to strict HR management responsibilities that prevent employees from driving drunk. As an invention that may be used in a system that prevents such drunk driving, a mobile phone with an alcohol detection function has been proposed (Patent Document 1).

JP 2001-313696 A

  However, the present invention is originally intended for a simple warning device for individuals, and is not applicable to crew members of business vehicles such as buses, trucks, and trains. That is, it is not considered at all that the alcohol sensor deteriorates due to daily use, and it cannot be used at all for management of business vehicles. Moreover, since the entire system is integrated, it is almost impossible to modify the equipment to improve the accuracy of alcohol testing. The problem is that the equipment that was prepared first must be discarded or used with low functionality. There is also.

  The present invention has been made in view of the above-described problems, and provides an operation management system capable of performing a high-precision alcohol test and easily adding and improving functions as necessary. Is an issue. Another object of the present invention is to provide an inspection adapter and a program used in such an operation management system.

In order to solve the above problems, the present invention has a camera capable of photographing a subject, can transmit and receive data via a mobile communication network, and is equipped with an application program for operation management. And a detection sensor capable of detecting the alcohol concentration, and one or a plurality of related sensors capable of detecting the expiration behavior of the subject in the detection sensor, and between the portable handset without using a wiring cable An operation management system comprising: a test adapter that performs data transmission / reception processing; and a management computer that receives transmission data related to a breath test of a subject who is a crew member from a portable handset, and manages a breathing abnormality of the crew member. And an imaging means for acquiring a camera image of the subject after prompting the subject to perform an operation necessary for the breath test, which is executed by the portable cordless handset, and a breath test An acquisition unit that is executed by the test adapter that has started the operation, determines the breathing behavior of the subject based on the output of the related sensor, and acquires the breathing test data of the subject based on the output of the detection sensor at that timing; The first transmission means for transmitting the breath test data to the portable handset and the portable means for receiving the breath test data from the test adapter. And a second transmission means for transmitting to the management computer together with the camera image photographed, the subject's ID information, and the time information .

  In the present invention, since the inspection adapter and the portable child device are separate, each can be freely maintained. For example, it is easy to replace a deteriorated sensor unit, and it is very easy to add or change functions by improving an application program.

  In the present invention, the measurement target during passenger expiration is not particularly limited, but includes at least the alcohol concentration. By using ethanol or the like as a measurement target, it is possible not only to detect a drunk state or hangover, but also to detect abnormalities in the stomach and intestines, which greatly contributes to the health management of the passenger. Moreover, in order to detect alcohol concentration in exhalation reliably, any one or more of temperature sensor, humidity sensor, pressure sensor, and flow sensor is used in combination with the alcohol sensor. Is preferred. When one or more sensors are used in combination, the spraying operation can be confirmed by the output of the plurality of sensors changing synchronously.

  Also preferably, the two alcohol sensors should be placed out of position. In this case, the main sensor is arranged at the optimum position, while the sub sensor is arranged at a position away from the optimum position. The deterioration of the main sensor can be immediately detected by constantly comparing the detection levels of the two sensors.

  In the present invention, preferably, the portable cordless handset and the inspection adapter are each provided with a transmission / reception unit that enables infrared communication. In addition, the inspection adapter is connected to a shut-off circuit that controls the start of the vehicle, and if the exhaled data of the vehicle occupant is at an abnormal level, operating the vehicle to prohibit the start of the vehicle Can be perfect. The application program is preferably configured to operate on a JAVA (registered trademark) virtual machine. In this case, the same application program can be used regardless of the model.

  The information for identifying the crew member is preferably ID (identification) information of the crew member and / or image data of the crew member obtained during the inspection operation. Further, it is simple that the portable handset is composed of any one of a mobile phone, a PHS (Personal Handy-phone System), and a PDA (Personal Digital Assistant).

  Moreover, this invention is also a portable cordless handset used with said operation management system, and an application program used with this portable cordless handset. Furthermore, the present invention is also an inspection adapter used in the above operation management system.

  According to the present invention described above, it is possible to realize an operation management system that can perform a high-accuracy alcohol test and can easily add and improve functions as necessary. Moreover, the test | inspection adapter and program which are used with such an operation management system are realizable.

It is a block diagram which shows the safe driving management system which concerns on an Example. It is a block diagram which shows the internal structure of a test | inspection adapter and a mobile telephone. It is a flowchart explaining the operation | movement content of a mobile telephone. It is a flowchart explaining the operation | movement content of a test | inspection adapter. It is a time chart explaining an infrared wireless communication concretely.

  Hereinafter, the present invention will be described in more detail based on examples. FIG. 1 is a block diagram showing the overall configuration of the safe driving management system SYS. This safe driving management system SYS is applied to, for example, the transportation industry such as long-distance buses and long-distance trucks, and is used for ensuring safe driving by reliably preventing drunk driving by bus or truck drivers. .

  As shown in the figure, the safe driving management system SYS according to the embodiment outputs a general-purpose mobile phone 1 possessed by a driver (vehicle occupant), a test adapter 2 for measuring a driver's breath alcohol concentration, and a test adapter 2. A shut-off circuit 3 for shutting off the energization of the cell motor by a control signal to prohibit the start of the vehicle, and a management computer 4 for receiving transmission information from the mobile phone 1 via the mobile communication network MMET and the Internet line INET , Mainly. The mobile phone 1 is wirelessly connected to the wireless base station 5 of the mobile communication network MNET and wirelessly connected to the inspection adapter 2 by infrared rays. The inspection adapter 2 operates by receiving the battery voltage of the automobile.

  FIG. 2 is a block diagram showing circuit configurations of the mobile phone 1 and the inspection adapter 2. The mobile phone 1 realizes a photography function, an information transmission function, an infrared communication function, and the like by a main control unit 10 that is a computer circuit including a CPU and a memory.

  The photography function is realized by the CCD camera 11, the camera interface unit 12, and the main control unit 10, and the acquired image data is temporarily stored in the memory of the main control unit 10.

  The information transmission function is realized by the main control unit 10 and the wireless transmission / reception unit 13, and in this embodiment, the image data acquired from the CCD camera 11 and the inspection data acquired from the inspection adapter 2 are appended with additional information. Information is transmitted to the management computer 4.

  Specifically, the client 1 (mobile phone) executes a “PUT operation request” to the server 4 (management computer) according to a procedure according to HTTP (Hyper Text Transfer Protocol), and header information (object name) , Type, size, timestamp, etc.) along with the object body (transmission information). Upon receiving this, the server 4 returns a response status to the client 1 by a “PUT operation response”.

  The infrared communication function is realized by the main control unit 10 and the infrared communication module 14, and specifically, conforms to the IrDA (Infrared Data Association) standard with other infrared communication modules by using infrared light with a wavelength of 850 to 900 nm. Realized optical communication. The communication method is a half-duplex serial method, and the communication range is about 1 m.

  In addition, the mobile phone 1 exhibits an image display function on the liquid crystal display unit LCD and a voice call function, but the illustration of the other components except the display control unit 15 is omitted. .

  By the way, the mobile phone 1 is configured to incorporate a JAVA virtual machine 100 and to execute an application program described in JAVA language. Here, the JAVA virtual machine means a software environment in which JAVA byte code (intermediate execution code generated by a JAVA compiler) is converted into native code unique to each CPU in an interpreter format and executed.

  The above-described photography function, infrared communication function, and information transmission function are realized on the JAVA virtual machine by an application program composed of JAVA byte codes together with other functions. That is, the JAVA virtual machine 100 is provided with an inspection processing guidance processing unit, a camera drive processing unit, an inspection data acquisition processing unit, and a transmission information transmission processing unit. In addition, it is natural that all the processes are actually executed in the main control unit 10.

  On the other hand, the inspection adapter 2 includes a microcontroller (one-chip microcomputer) 20 that supervises the entire operation of inspection processing, an infrared communication module 21 that realizes half-duplex serial communication between the mobile phone 1, an alcohol sensor AS, Receives an instruction signal from a concentration detection circuit 22 that measures the alcohol concentration in the subject's breath by receiving an analog signal from the humidity sensor HU, an LED circuit 23 that drives the LED lamp group, and a test start switch SW that also serves as a power switch. A switch circuit 24, a power supply circuit 25 that steps down or boosts a DC voltage received from the automobile battery and supplies the voltage to each unit, and a 7-segment LED display unit 26 are included.

  The inspection start switch SW also serves as a power switch, and functions as a power-on switch when the power of the inspection adapter 2 is shut off. On the other hand, after the power is turned on, the subject functions as an inspection start switch that instructs the inspection adapter 2 to start the inspection operation.

The alcohol sensor AS is not particularly limited, but in this embodiment, a “surface-controlled semiconductor gas sensor” that utilizes the fact that gas (here, ethanol) undergoes an adsorption reaction on the surface of an oxide semiconductor and changes its electrical resistance. I use it. Note that an n-type semiconductor such as SnO ₂ or ZnO is used as the oxide semiconductor. Since the surface-controlled semiconductor gas sensor needs to be heated to a predetermined temperature, a heater circuit HT is provided close to the alcohol sensor AS, and the alcohol concentration is measured on the condition that the alcohol sensor AS has reached the predetermined temperature. Like to do.

  In this embodiment, two alcohol sensors AS1 and AS2 are provided. 1st alcohol sensor AS1 is arrange | positioned in the position which captures expiration in the optimal position as a main sensor. On the other hand, the second alcohol sensor AS2 is disposed as a sub sensor on the downstream side of the main sensor as viewed from the subject. Therefore, the second sensor AS2 cannot accurately measure the alcohol concentration of the subject, but on the other hand, the subject's saliva and sigh condensation do not adhere, and the progress of deterioration is less than that of the first sensor. Very slow. Therefore, in this embodiment, the first and second sensor outputs are always compared, and the deterioration of the main sensor is determined based on the comparison result. If the deterioration is found, the main sensor is replaced with the sub sensor.

  On the other hand, the humidity sensor HU is a sensor that detects that the subject blows exhaled breath on the alcohol sensor AS, and the output of the alcohol sensor AS is captured in accordance with the timing at which the output signal from the humidity sensor HU changes. In this embodiment, an “impedance change sensor” is used as the humidity sensor. Here, the impedance change sensor means a substance whose electrical resistance changes depending on humidity, such as an electrolyte, a polymer, and a metal oxide (ceramic). A wind pressure sensor or a temperature sensor may be provided in place of or in addition to the humidity sensor.

  The LED lamp group includes a power lamp PWR indicating a power-on state, a ready lamp RDY indicating that the alcohol sensor AS has reached a predetermined temperature by turning on the inspection start switch SW, and normal indicating that the inspection process has been completed normally. The lamp is OK. When the inspection process is completed normally, the ready lamp RDY is turned off and the normal lamp OK is turned on. However, if the alcohol test cannot be performed successfully, the ready lamp RDY remains turned on and the normal lamp OK flashes. ing. Therefore, when the normal lamp OK is blinking, the subject presses the switch SW again and re-executes the inspection process.

  The 7-segment LED display unit 26 is a part that numerically displays the inspection result. When the inspection data cannot be normally acquired, an error notification to that effect is executed.

  The microcontroller 20 includes an A / D converter 201 that converts an analog signal received from the concentration detection circuit 22 into a digital signal, a first output port 202 that outputs drive data to the LED circuit 23, and an operation from the switch circuit 24. The first input port 203 that receives the start signal, the serial input / output port 204 connected to the infrared communication module 21, the second output port 205 that outputs drive data to the 7-segment LED display unit 26, and the cutoff circuit 3 A third output port 206 that outputs a control signal, a CPU core 200 that controls the operation of each unit, a ROM 207 that stores a control program that defines the operation content of the CPU core 200, and a work area in the control operation of the CPU core 200 And a RAM 208.

  Next, an operation method of the safe driving management system SYS having the above configuration will be described. The long-distance bus and truck are each equipped with an inspection adapter 2 and a shut-off circuit 3, and it is obliged to always carry the portable handset 1 when the driver is engaged in long-distance work. And it is obliged to perform an alcohol test several times a day (for example, after a meal).

  In the alcohol inspection, an application program for inspection support installed in the portable handset 1 is activated. As described above, the inspection support program functions on the JAVA virtual machine. FIG. 3 is a flowchart showing the operation content.

  As shown in the figure, first, a process (ST1) for specifying a subject is started. Specifically, an input of an ID (identification) number assigned to each driver is accepted. Since the mobile phone 1 is lent to all drivers and the ID number registered first is stored as a default value, in the process of step ST1, it is actually checked whether the default value is correct. (ST1). However, if the own ID number is different from the default value, the correct ID number is re-input and set.

  Subsequently, for example, “Please press the power switch of the test adapter until it beeps briefly” is displayed on the liquid crystal display LCD (ST2). Next, the power switch SW of the inspection adapter 2 is turned on, and the apparatus waits until the heater HT is heated to a predetermined temperature (ST3, ST4). Specifically, it waits to receive “ready data” from the inspection adapter 2 via the infrared communication module 14.

  In the infrared communication modules 14 and 21 of this embodiment, a carrier wave of about 25 KHz to 50 KHz is PPM (Pulse Code Modulation) modulated by a control signal (FIG. 5A), and a PPM phase modulated wave (FIG. 5B). Is formed. Infrared data transmission is realized by irradiating infrared light corresponding to the PPM phase modulation wave. Here, infrared data transmission is executed in units of data frames including a start unit, a stop unit, and a main unit (FIG. 5C). The start part is composed of an H level section of a predetermined time T1 and an L level section of a predetermined time T2, and the stop section is composed of an H level section of a predetermined time T3.

  Therefore, the standby processing of steps ST3 and ST4 ends when “preparation completion data” of a predetermined bit pattern is acquired in the processing of step ST43 of FIG. However, there is a possibility that "preparation completion data" will not be received no matter how long it waits due to a driver's operation error, etc. In the case of such a time over error, an error is notified to the liquid crystal display LCD and processed. Finish.

  In normal cases, preparation completion data is received within a predetermined time. Next, a message such as “Check the alcohol with the camera facing your face” is displayed on the LCD. Then, the shooting operation by the camera is started (ST6). After that, when the camera preparation operation is completed, the camera shutter is automatically released to photograph the test operation of the subject, and the acquired photographing data is stored (ST7).

  After that, it waits for the inspection adapter 2 to transmit inspection data, and the transmitted inspection data is sequentially stored in the memory (ST8). When reception of all the check data is completed, it is confirmed that there is no reception abnormality by cyclic redundancy check (CRC) or the like (ST9). If there is a communication abnormality, the inspection data is received again. Note that the inspection adapter 2 is configured to repeatedly transmit inspection data unless it receives a normal acquisition response from the mobile phone (ST26 to ST29 in FIG. 4).

  As a result, if the CRC values of the received inspection data match, OK data indicating that the inspection data has been successfully received is transmitted to the inspection adapter 2 (ST11). On the other hand, if a time-over error occurs in which the inspection data cannot be acquired normally even after a predetermined time has elapsed, an error notification is given to the liquid crystal display LCD, and the process is terminated.

  If the process of step ST11 is completed due to the normal completion of the reception process, then necessary data is transmitted to the management computer 4. The transmission information transmitted here includes an alcohol concentration as a test result, a driver ID, a test time, and imaging data. Here, the alcohol concentration is a detection value of the main sensor and a reference detection value of the sub sensor. Therefore, the management computer 4 can grasp the deterioration state of the main sensor by comparing the detection values of the main sensor AS1 and the sub sensor AS2.

  If the current position of the mobile phone can be acquired by the application program, the current position data is transmitted in addition to the above data. As described above, the transmission process is executed as a “PUT operation request” for the server 4.

  Then, since the response status is returned from the server 4 as a “PUT operation response”, if the status is abnormal, the retransmission processing is executed, and if the status is normal, the communication processing is terminated. Then, the fact that all the processes have been normally completed is displayed on the liquid crystal display unit LCD, and the process ends.

  The application program (inspection support program) has been specifically described above. In the JAVA virtual machine 100, the inspection processing guidance processing units (ST1 to ST6), the camera drive processing unit (ST7), and the inspection data acquisition processing The units (ST8 to ST11) and the transmission information transmission processing units (ST12 to ST13) are each realized by processing in parentheses.

  FIG. 4 is a flowchart showing the processing of the inspection adapter 2. Corresponding to the inspection process guidance process in the mobile phone 1 described above, when the driver presses the power switch SW of the inspection adapter 2 until a short beep sounds, the heater HT is energized and the alcohol sensor AS is turned on. A heating operation is started (ST20).

  When a predetermined time has elapsed from the start of energization of the heater HT, the microcontroller 20 drives the LED circuit 23 to turn on the ready lamp RDY. Also, preparation completion data is transmitted to the mobile phone 1 (ST22).

  On the other hand, in response to the lighting operation of the ready lamp RDY, the driver seems to blow exhalation toward the test probe in which the alcohol sensor AS and the humidity sensor HU are integrated. Since the signal from the alcohol sensor AS and the signal from the humidity sensor HU are synchronously input to the microcontroller 20, the microcontroller 20 can know the expiration operation by a significant increase in humidity. The density is stored in the RAM 207 (ST23). In accordance with this storage operation, the microcontroller 20 drives the LED circuit 23 to turn off the ready lamp RDY and turn on the OK lamp. The LED display unit 26 displays the stored measurement result as a numerical value. The display is based on the detection result of the main sensor AS1, and the detection result of the sub sensor AS2 is not displayed.

  By the way, when detecting an abnormal situation such as no significant increase in humidity, the microcontroller 20 drives the LED circuit 23 to blink the OK lamp to instruct the subject to perform a retest. (ST25). In addition, a message to that effect is displayed on the LED display 26 (ST25).

  When the alcohol concentration can be normally measured by the above-described inspection process, the microcontroller 20 sends the inspection data indicating the inspection results of the two alcohol sensors AS1 and AS2 to the mobile phone 1 through the infrared communication module 21. Transmit (ST26). And it waits for the OK data which shows a normal reception state to be transmitted from the mobile telephone 1 (ST27).

  When the normal reception state is confirmed, the processing is finished as it is. However, if the communication is abnormal, the abnormality counter ER is incremented by 1 (ST28), and the inspection is repeated unless the counter value exceeds the upper limit MAX. Data is transmitted (ST26). As a result, it seems that the inspection data is transmitted normally, but if the driver cannot receive the OK data due to an operation error such as accidentally terminating the application of the mobile phone, The lamp is displayed to indicate the state, and the process ends.

  In the process of step ST23, after the alcohol concentration is acquired, if it is an abnormal level, a control signal is output to the cutoff circuit 3 and the activation of the cell motor is prohibited. However, a priority switch (not shown) for disabling the shut-off circuit 3 is provided in consideration of the possibility of equipment abnormality of the inspection adapter 2, and after telephone notification to the management headquarters using the mobile phone 1, It is possible to start the car.

  As described above, in this embodiment, by effectively utilizing the mobile phone, it is possible to reliably collect the test results of the alcohol test by the driver, and to reliably prevent drunk driving. Moreover, since the test adapter is separate from the mobile phone, the test adapter 2 and the application program of the mobile phone 1 can be individually upgraded, and the test accuracy of alcohol test can be increased. . Further, since the sub sensor is arranged at a position downstream of the main sensor and hardly deteriorated by the exhalation of the subject, the use limit of the main sensor can be accurately grasped by comparing both levels.

  In addition, since it is not necessary to incorporate an alcohol test circuit in the mobile phone, a commercially available mobile phone can be used. In addition, since it is only necessary to install an application program in the JAVA language in a mobile phone, there is an advantage regardless of the type or the type of CPU as long as the mobile phone is equipped with a JAVA virtual machine.

  During the inspection operation, the camera built in the portable handset is activated to automatically photograph the subject's inspection scene, and this is transmitted along with the inspection data to the management computer. Can be prevented.

  Although the embodiments of the present invention have been described above, the specific contents do not particularly limit the present invention. For example, in the embodiment, data is transmitted and received between the mobile phone and the inspection adapter using infrared communication. Instead, in accordance with a short-range wireless communication standard such as Bluetooth or ZigBee (each is a registered trademark). You may connect. Here, Bluetooth is a wireless communication technology specialized for connection to a short-distance device using the 2.4 GHz frequency band, and is standardized by IEEE 802.15.1. Also, ZigBee uses IEEE 802.15.4 for the physical layer interface and uses the 2.4 GHz frequency band.
