  FIG. 1 is a block diagram conceptually showing a pollution evaluation system according to the present invention. The contamination evaluation system includes a contamination evaluation device 1, a position detector 2 and a database 3.

  The position detector 2 can detect the current position and detects the current position as the position x. Then, the position x is given to the contamination amount evaluation apparatus 1 together with the detected time t. The position x indicates a room such as a public facility or an outdoor place.

  For example, a portable global positioning system receiver can be adopted as the position detector 2. FIG. 2 shows a case where the global positioning system receiver 2 is carried by a movable unit 100 that is a position detection target. The global positioning system receiver 2 receives the radio wave R1 emitted from the artificial satellite 22, and detects the position based on the radio wave R1. That is, the position of the movable body 100 that carries the position detector 2 is detected.

  The movable body 100 that is the position detection target may carry a portable transmitter 21. FIG. 3 shows this case. The position detector 2 is provided at a position different from the movable body 100. And the radio wave R2 generated from the transmitter 21 is received, and the position of the transmitter 21 is detected based on the radio wave R2. That is, the position of the movable body 100 including the transmitter 21 is detected. The transmitter 21 can be, for example, a mobile phone or a personal handyphone system (PHS) terminal device.

  The contamination amount evaluation apparatus 1 includes a position storage unit 11, a data acquisition unit 12, and a calculation unit 13. The position storage unit 11 stores the position x and time t given from the position detector 2.

  The data acquisition unit 12 reads the position x and the time t from the position storage unit 11 and acquires data S about the contamination intensity C at the position x at the time t from the outside. Here, the contamination intensity C represents the dose C1 per unit time for electromagnetic waves such as radioactivity, and the concentration C2 for chemical substances such as dioxin. The data S may include intensities for each of the plurality of types of contamination, for example, the dose C1 and the concentration C2, or may include only one of the intensities.

  The data S is stored in, for example, the database 3 outside the contamination amount evaluation apparatus 1. Then, the data acquisition unit 12 acquires data S from the database 3. This case is shown in FIGS.

  The contamination intensity C acquired as data S by the data acquisition unit 12 may be, for example, a value actually measured at the position x at time t, or may be a value obtained by simulation. A method for obtaining the contamination intensity C, particularly the concentration of a chemical substance or the like by simulation is disclosed in, for example, Patent Document 1 described above.

  The calculation unit 13 acquires the time t and the data S from the data acquisition unit 12, and based on these, the movable body 100 (FIG. 2) carrying the position detector 2 or the movable body 100 carrying the transmitter 21 (FIG. 3). ) Calculate the amount of contamination exposed. Specifically, it is calculated as follows.

  For example, when the movable body 100 is exposed by electromagnetic waves such as radiation, the dose C1 per unit time is adopted as the contamination intensity. And the calculating part 13 calculates the total amount L1 of the exposed electromagnetic waves as the amount of contamination which the movable body 100 exposed, for example by integrating the dose C1 per unit time at the time t.

  For example, when the movable body 100 is exposed by a chemical substance, the chemical substance concentration C2 is adopted as the intensity of contamination. For example, when the movable body 100 is a person, the calculation unit 13 multiplies the respiration rate and the concentration C2 per unit time of the person, and the unit that the person ingests, that is, the person exposes per unit time. Find the amount of contamination per hour. Then, the total amount L2 of the exposed chemical substance is calculated as the amount of contamination exposed to the movable body 100 by integrating the amount of contamination per unit time at time t.

  The respiration rate per unit time described above can be grasped as the sensitivity a to the contamination of the movable body 100. At this time, the above-described content can be grasped when the calculation unit 13 obtains the contamination amount L2 to which the movable body 100 is exposed based on the contamination intensity C2, the time t, and the sensitivity a.

  FIGS. 4 and 5 show cases where the contamination amount evaluation apparatus 1 shown in FIGS. 2 and 3 further includes a sensitivity storage unit 14. The sensitivity a is stored in the sensitivity storage unit 14, for example. The calculation unit 13 acquires the sensitivity a from the sensitivity storage unit 14 and calculates the amount of contamination that has been exposed as described above.

  The calculation unit 13 may further calculate the probability that the state of the movable body 100 such as a person will deteriorate based on the contamination amounts L1 and L2. According to this, the probability that the state of the movable body 100 is deteriorated can be known, and for example, it is possible to cope with the deteriorated state in advance.

  The sensitivity a described above may be, for example, the sensitivity of the movable body 100 to contamination, specifically, the degree of an allergic reaction that a person exhibits with respect to predetermined contamination. For example, if the degree of allergic reaction to a given contamination is high, it can be considered that a greater amount of contamination has been exposed by multiplying the amount of contamination actually exposed by the given contamination by a factor greater than 1, for example. Good.

  According to such estimation of the amount of contamination, the sensitivity to the contamination of the movable body 100 is taken into account, so that the probability that the state of the movable body 100 is deteriorated can be known more accurately.

  According to the above-described technology for evaluating the amount of contamination, the amount of contamination exposed to the movable body 100 can be obtained without using an exposed badge. Furthermore, it is possible to know the probability that the state of the movable body 100 will deteriorate based on the amount of contamination. In addition, since the amount of contamination can be obtained for each type, the influence of a plurality of types of contamination on the movable body 100 can be estimated without using a plurality of types of exposure badges.

  Here, the case where the movable body 100 is mainly a person has been described as an example. However, it is obvious that other movable bodies, such as work robots, may be used. For example, the present invention can also be applied when the components of the work robot are deteriorated by a specific chemical substance such as sulfide.

It is a figure which shows notionally the movable body 100 which carries a global positioning system receiver.
