Description

  The present invention relates to wireless communication technology, and more particularly to a portable information transmitting / receiving apparatus.

During large-scale disasters, how to collect information on the safety of disaster victims and how to communicate them to third parties are important issues. In recent years, due to the rapid spread of mobile radio communication systems such as mobile phones and PHS, opportunities to use mobile radio communications for emergency communications such as disasters have increased (for example, see Patent Document 1). Wireless communication such as regional disaster prevention radio is also used in public disaster emergency communication systems. However, due to a sudden increase in communication traffic at the time of a disaster, congestion occurs and the problem of communication failure occurs frequently. In a fixed telephone that is wired communication, not only congestion, but also a communication failure occurs due to a physical disconnection of a telephone line that constitutes a communication network due to a disaster. In an emergency such as a disaster, it is important to transmit information about the victim easily, quickly and reliably by means of communication that avoids communication failures.

  Next, using the flowchart shown in FIG. 7, focusing on the first portable information transmitting / receiving device 10 in the first communication area 603 of FIG. 5, the operation of the first portable information transmitting / receiving device 10 will be described.

  (A) As shown in FIG. 7, the first portable information transmitting / receiving device 10 of FIG. 4 receives emergency disaster information transmitted from the disaster information transmitting station 604 shown in FIG. 5, creates a safety information response message, and records it. In the steps up to transmission to the predetermined transmission destination, step S210 is added as shown in FIG. 7, and the processing content of step S206 is changed. That is, steps S101 to 105 and steps S107 to 109 shown in FIG. 4 and steps S201 to 205 and steps S207 to 209 shown in FIG. However, step S106 creates a safety information response message composed of the personal information of the user of the first portable information transmitting / receiving device 10, a response message template, and emergency disaster additional information, whereas step S206 is step S106. The processing content of step S206 is changed from step S106 in that a safety information response message is created with a configuration in which the location information detected by the location information detection unit 201 is added to the safety information response message created in step S106.

(B) In step S210, the first portable information transmitting / receiving apparatus 10 of FIG. 6 receives radio waves output from a plurality of satellites, and is calculated by the GPS function from the orbit information of each satellite. The position information of the device 10 is detected. The detected location information of the first portable information transmission / reception device 10 is sent from the location information detection unit 201 as the location information of the first portable information transmission / reception device 10 to the message creation unit 105b. In step S206, the message creation unit 105b that has received the location information of the first portable information transmission / reception device 10 receives the personal information of the user of the first portable information transmission / reception device 10, a response message template, and the contents and location of the emergency disaster additional information. A safety information response message is created from the position information received from the information detection unit 201 and recorded in the message storage unit 106.

Information is detected and added to the safety information response message. Therefore, the safety information response message recipient who can receive and browse the safety information response message from the disaster victim compares the disaster area information with the location information of the disaster victim, and more specifically determines the safety of the disaster victim. I can grasp it.

  The first portable information transmission / reception device 10 has been described above, but the same applies to other portable information transmission / reception devices such as the second portable information transmission / reception device 20 and the third portable information transmission / reception device 30.

(Third embodiment)
The wireless communication system using the portable information transmitting / receiving apparatus according to the third embodiment of the present invention shown in FIG. 5 has the same area configuration as FIG. In this area configuration, the safety information response message from the portable information transmitting / receiving device in the first communication area 603 is relayed to the first communication base station 605 via the wireless transmission path and transmitted to the communication network 601.

  The details of the first portable information transmitting / receiving apparatus 10 arranged in the first communication area 603 of FIG. 5 which is the portable information transmitting / receiving apparatus according to the third embodiment are as shown in FIG. This is a device in which a disaster impact assessment determination unit 301 is added to the information transmitting / receiving device 10. The disaster impact assessment determination unit 301 includes the type and scale of the disaster constituting the emergency disaster additional information, which is additional information included in the emergency disaster information, and the local information on the disaster area and the first portable information detected by the location information detection unit 201 The position information of the transmission / reception device 10 is compared, evaluated, and determined based on a pre-defined index recorded in the disaster impact assessment determination unit 301, and the processing after step S312 is limited. The index defined in advance is set as an index value that serves as an evaluation criterion when the disaster impact evaluation determination unit 301 compares, evaluates, and determines.

  Here, the index value as an evaluation criterion can be flexibly changed by the user of the first portable information transmitting / receiving device 10 in consideration of the magnitude of the influence of the disaster scale. For example, the index location can be defined as an average value of two values including “disaster information reception area range” and “disaster scale”. The evaluation condition can be defined as “evaluation target value at the time of disaster occurrence ≧ index value”. In this case, for example, if the constituent element [disaster information reception area range, disaster scale] of the index value is set to [5, 3], the index value becomes 4. At this time, if the value [disaster information receiving area range, disaster scale] at the time of the disaster is [4, 5], the evaluation target value at the time of the disaster is 4.5 and satisfies the evaluation condition. “Yes”, and the safety information response message is transmitted to the transmission target person. If the value at the time of disaster [disaster information receiving area scale, disaster scale] is [3, 2], the evaluation target value at the time of disaster is 2.5, which does not satisfy the evaluation condition. The answer is “No” and the safety information response message is discarded. Here, for example, the “disaster information reception area range” is “1” when “the distance from the disaster occurrence place to the first portable information transmitting / receiving device 10 is 800 to 1000 km”, and “from the disaster occurrence place to the first portable information transmitting / receiving device 10”. Can be set to "2", ..., "Distance from the disaster occurrence place to the first portable information transmitting / receiving device 10 is 0 to 200km" is "5". In addition, the “scale of disaster” can be set such that “Magnitude 1” is “1”, “Magnitude 2” is “2”,..., “Magnitude 5” is “5”. The types of elements constituting the indexes, such as the above-mentioned rules, set values, evaluation conditions, etc., the weights for each element, the number of elements or the calculation method of the index values, etc. are the disaster evaluation policies of the user of the first portable information transmitting / receiving device 10 It is decided by. If an index value and an evaluation condition serving as an evaluation standard are set as a disaster evaluation policy on the safety side, a safety information response message is transmitted even when a direct disaster does not occur, and the transmission traffic of the message increases. Accordingly, the burden of both the monetary cost of the user of the first portable information transmitting / receiving device 10 and the network cost of the user of the other first portable information transmitting / receiving device 10 using the network increases. On the other hand, if the index value and the evaluation condition that are the evaluation criteria are set on the dangerous side as the disaster evaluation policy, the network cost can be reduced due to the monetary cost and wasted traffic, but the first portable information transmitting / receiving device 10 Even if the user is affected by a disaster, a message may not be transmitted, and the original useful effect of the first portable information transmitting / receiving device 10 may not be obtained. Although not shown, the second portable information transmitting / receiving device 20 and the third portable information transmitting / receiving device 30 have the same configuration as the first portable information transmitting / receiving device 10.

  Next, using the flowchart shown in FIG. 9, focusing on the first portable information transmitting / receiving device 10 in the first communication area 603 of FIG. 5, the operation of the first portable information transmitting / receiving device 10 will be described. In the steps until the first portable information transmitting / receiving device 10 in FIG. 6 receives emergency disaster information transmitted from the disaster information transmitting station 604, creates a safety information response message, and transmits it to the recorded destination. Step S311 and step S312 are added. Note that steps S201 to S210 in FIG. 7 and steps S301 to S310 in FIG. 9 perform the same processing.

  (A) In step S311, the disaster impact assessment determination unit 301 in FIG. 8 types of disasters constituting the emergency disaster additional information that is additional information included in the emergency disaster information transmitted from the disaster information transmission station 604 in FIG. Based on a predetermined index recorded in the disaster impact assessment determination unit 301, the area information regarding the disaster area, the location information of the first portable information transmission / reception device 10 detected by the location information detection unit 201. Compare and evaluate. Here, the pre-defined index recorded in the disaster impact assessment determination unit 301 is the impact of the disaster on the object of comparative evaluation, that is, the user of the first portable information transmitting / receiving device 10 due to the occurrence of the disaster. It is an evaluation standard determined by factors and calculation methods considered to be deaf.

  (B) If the evaluation result based on the index that is the evaluation criterion satisfies the evaluation condition, the evaluation result is determined to be “Yes” in step S312, the process proceeds to step S306, and the message creating unit 105b receives the first portable information. A safety information response message composed of the personal information of the user of the transmission / reception device 10, the contents of the emergency disaster additional information, the position information, and the response message template is created. If the evaluation result does not satisfy the evaluation condition, the evaluation result is determined as “No” in step S312, and the process proceeds to step S309, and the process ends without creating a safety information response message.

  As described above, the portable information transmitting / receiving apparatus according to the third embodiment can be set to limit the transmission process of the safety information response message based on the disaster information and the position information of the user of the first portable information transmitting / receiving apparatus 10.

The communication module priority determination method is based on the rules for determining the communication module selection priority set in advance in the communication module priority determination unit 401, and the factors affecting the actual communication such as the disaster status or the communication status. Determined as a parameter. Each of the plurality of communication modules adopts any one of wireless communication methods that the communication unit 109 according to the first embodiment can take. Also, the rule for determining the priority when the communication module priority order determination unit 401 selects a communication module having a communication method that enables optimal communication from a plurality of communication modules is, for example, in the communication area The size, the distance from the first portable information transmitting / receiving apparatus 10 to the communication base station, the disaster situation of the communication base station, and the like are defined as elements. Regarding the communication area, the larger the area, the larger the number of users of the other first portable information transmitting / receiving devices 10 existing in the same area. Therefore, the generated traffic increases and the possibility of communication being restricted increases. . In that case, a communication method with a small communication area is set high as a priority. Further, regarding the distance from the first portable information transmitting / receiving device 10 to the communication base station, the distance from the first portable information transmitting / receiving device 10 from the viewpoint of the possibility of radio wave reflection, diffraction, and the cause of deterioration in communication quality due to distance attenuation. A communication method corresponding to a communication base station having a shorter is set as a higher priority. Furthermore, when the communication base station does not perform the original function as a communication base station due to a disaster, the target communication module is not set as a communication means. When sending a safety information response message, in order to determine the priority order when selecting the communication module that performs the optimal communication, what rule is used, which rule is applied among multiple rules, or multiple Based on past disasters and communication results at the time of a disaster, whether to apply as a new rule by combining these rules, or in which case, to determine which rule combination, etc., determines communication module priorities in advance. It is assumed that it is set in the unit 401.

Steps S411 and S412 are added in the steps from creation to transmission to a predetermined destination. Note that steps S201 to 207 and steps S209 to 210, steps S401 to 407, and steps S409 to 410 perform the same processing. However, step S208 in FIG. 7 and step S408 in FIG. 12 have only one communication module to which step S208 is fixed, and thus attempt to communicate by only one communication means in any disaster situation, communication environment, and communication situation. On the other hand, step S408 has a plurality of communication modules, and is different in that communication can be attempted using a communication means according to the priority order determined by the disaster situation, the communication environment, and the communication situation.

  (A) In step S411, the communication module priority order determination unit 401 in FIG. 11 performs optimal communication in performing communication for transmitting a safety information response message from among a plurality of communication modules constituting the communication unit 109. The priority of selecting a communication module having a communication method for realizing the above is determined according to a preset rule. When the communication module priority order determination unit 401 determines the priority order of communication modules with which communication is performed, the communication unit 109 performs communication using a communication module with a higher priority order. First, communication is attempted using the communication module with the first priority set.

  (B) If the transmission of the safety information response message is successful in step S408, the process proceeds to step S409 based on the result in step S412. If transmission of the safety information response message fails in step S408, the process proceeds to step S411 based on the result in step S412. At this time, in step S411, the communication unit 109 attempts communication using the communication module in which the second priority is set by the communication module priority determining unit 401. As described above, when the transmission of the safety information response message fails, the communication unit 109 communicates the communication modules constituting the communication unit 109 set with the priority by the communication module priority determination unit 401 with high priority communication. The modules are used in order, and communication is repeatedly attempted until the safety information response message is successfully transmitted.
