Referring to fig. 1, fig. 1 is a schematic flow chart of a communication method of an electronic dosimeter according to an embodiment of the present invention, where the method is applied to an electronic dosimeter to achieve efficient, low-cost, and secure communication between the electronic dosimeter and a dosimeter reader at present, and includes steps S101 to S105.
In step S101, the electronic dosimeter establishes a near field communication connection with the dosimeter reader.
In the related technology, the electronic dosimeter and the dosimeter reader are directly communicated, when certain communication requirements are met, the two communication modes are kept, such as infrared ray and radio frequency communication, only the requirement that the electronic dosimeter and the dosimeter reader are in communication distance (the communication distance of the infrared ray and the radio frequency can be expanded to several meters) is met, once an infrared ray and radio frequency transmitting module of the electronic dosimeter approaches the electronic dosimeter reader, information can be automatically sent unconditionally, the electronic dosimeter and the reader are always in a working state, the energy consumption requirement is increased, the electronic dosimeter is always in an active communication state, when measurement data are sent to the dosimeter reader, whether the reader is legal or not cannot be determined, and the effect of safety protection on the monitoring data of the electronic dosimeter cannot be achieved.
In this embodiment, a Near field communication connection is established between the electronic dosimeter and the dosimeter reader, specifically, a Near field communication module is disposed in the electronic dosimeter and the dosimeter reader, and a communication connection between the electronic dosimeter and the dosimeter is established through the Near field communication module, where Near field communication (NFC for short) includes three operation modes, namely an active mode, a passive mode, and a bidirectional mode, and in practical application, NFC is mainly applied to Near field wireless communication, where NFC and wireless communication modes such as infrared and radio frequency are applied to the electronic dosimeter, and compared with the case where the NFC and the wireless communication modes are applied to the electronic dosimeter, at least the following advantages exist:
(1) NFC communication mode diversity: there are three modes of operation for NFC, namely active, passive and bidirectional. Different working modes can be selected according to actual needs. Infrared communication relies primarily on communication between transmitting and receiving modules, and two communication devices must have separate sets of transmitting and receiving devices if two-way communication is required. The radio frequency is mainly applied to the field of identification as an electronic tag and is not communication in the true sense.
(2) The NFC communication capability is outstanding: the transmission of infrared rays and radio frequency has higher directivity requirements on a transmitting device and a reader-writer, signals are easily blocked by an object, and the NFC has no special requirements for the transmission. NFC, as a new communication technology developed on the basis of radio frequency communication, is downward compatible with radio frequency communication and can provide more data exchange than radio frequency technology. In addition, under the active and passive communication mode of NFC, the time for establishing communication connection is less than 0.1 second, and the electronic dosimeter is favorable for quick passing of personnel and improves the working efficiency in the application of sanitary entrances and exits of nuclear power plants in scenes with more electronic dosimeters.
(3) Safety: NFC communication needs to be carried out within the range of about ten centimeters of near field distance, communication cannot be carried out beyond the near field distance, and the communication distance of infrared rays and radio frequency can be expanded to several meters. The infrared and radio frequency transmitting modules can automatically send out information unconditionally once approaching the reader-writer, so that whether the reader-writer is legal or not can not be determined, and the safety protection NFC for the monitoring data of the electronic dosimeter has obvious advantages.
(4) Equipment cost: according to market research conditions, compared with infrared and radio frequency devices, NFC devices are lower in cost and energy consumption. The electronic dosimeter can be used as target equipment and adopts an NFC passive working mode, power supply is not needed when no communication requirement exists, and the radio frequency field energy of initiating equipment can be converted into a self power supply during data communication.
In step S102, the electronic dosimeter receives access from a dosimeter reader, so that the dosimeter reader accesses the electronic dosimeter, and based on the access result, sends authorization information and an activation instruction to the electronic dosimeter and starts an access control system of a workspace.
In radiation working environment such as nuclear power plant, when the staff gets into the work area, need wear the electron dosimeter and get into access control system, the staff can get into the work area when access control system passes through, and the electron dosimeter measures staff's radiation dosage parameter in the work area. Specifically, the electronic dosimeter is divided into a working area inlet activation and a triggering opening access control use in actual use, dosage measurement data are uploaded at a working area outlet, and correspondingly, the dosimeter reader sends authorization information and an activation instruction to the electronic dosimeter at the working area inlet and triggers the opening access control system, and the dosage measurement data transmitted by the electronic dosimeter are obtained at the working area outlet and sends a closing instruction.
In this embodiment, when the staff wears the electronic dosimeter and enters into workspace access control system, the dosimeter reader initiatively visits the electronic dosimeter, the electronic dosimeter is in the passive communication state in near field communication at this moment, the electronic dosimeter is as the communication target equipment, the dosimeter reader visits the information of the electronic dosimeter, wherein, the electronic dosimeter stores the information such as basic information and identification code of relevant staff, the dosimeter reader visits the electronic dosimeter through the electronic dosimeter to identify whether the electronic dosimeter is legal or not, when the electronic dosimeter is verified to be legal, the electronic dosimeter is issued authorization information and an activation instruction, the workspace access control system is opened simultaneously, the staff can enter into the workspace. It should be noted that in the initial state, the electronic dosimeter and the dosimeter reader are in passive communication, that is, the electronic dosimeter only passively receives access from the dosimeter reader and does not directly communicate with the dosimeter reader.
In step S103, the electronic dosimeter obtains authorization information and an activation instruction sent by the dosimeter reader, and enters a working state.
In the embodiment, the electronic dosimeter enters a working state after acquiring the authorization information and the activation instruction sent by the dosimeter reader through near field communication, at the moment, the electronic dosimeter is converted into three communication modes, namely an active communication mode, a passive communication mode and a two-way communication mode, through passive communication in an inactivated state, and the electronic dosimeter can select different working modes according to actual requirements.
In a specific embodiment, after obtaining the authorization information and the activation instruction sent by the dosimeter reader and entering the working state (i.e., step S101), and before continuously collecting the dose measurement data (i.e., step S103), the method further comprises the steps of:
and receiving the measurement parameters sent by the dosimeter reader.
Specifically, the dosimeter reader receives measurement parameters sent by the dose monitoring network device and transmits the measurement parameters to the electronic dosimeter, wherein the measurement parameters are set according to the radiation condition of a working area.
In step S104, after the electronic dosimeter enters the working area, the electronic dosimeter continuously collects dose measurement data.
In this embodiment, the electronic dosimeter continuously collects various dose measurement data of human body radiation based on measurement parameters sent by the dosimeter reader, and specifically, collects various dose measurement data of human body chest.
In step S105, after the electronic dosimeter leaves the workspace, the electronic dosimeter accesses the dosimeter reader and uploads the acquired dose measurement data to the dosimeter reader.
In this embodiment, after the staff leaves the workspace, the electronic dosimeter actively accesses the personal dose reader and uploads the dose measurement data to the dosimeter reader, and the dosimeter reader records the dose measurement data of the staff.
In a specific embodiment, after the electronic dosimeter leaves the workspace, the dosimeter reader is accessed and the dose measurement data is uploaded to the dosimeter reader (i.e., after step S105), the method further comprises step S106:
in step S106, the electronic dosimeter receives access of the dosimeter reader again, and acquires a shutdown command sent by the dosimeter reader to stop working.
It should be noted that step S106 may be performed after step S105, or may be performed simultaneously, where the electronic dosimeter and the personal dose reader complete bidirectional communication — the electronic dosimeter accesses the personal dose reader to upload measurement data, and the personal dose reader accesses the electronic dosimeter and issues a shutdown command, and the electronic dosimeter stops working after receiving the shutdown command.
Specifically, the electronic dosimeter is used as a target device in passive communication, and external power supply is not needed during non-data transmission. When the dosimeter reader is used as data transmission initiating equipment to read data of the electronic dosimeter of the target equipment, the electronic dosimeter of the target equipment can convert Radio Frequency field (RFfield) energy of the initiating equipment into a Direct Current (DC) power supply to supply power to the electronic dosimeter of the target equipment by utilizing a full-wave rectification line, and finally data communication between the target equipment and the initiating equipment is completed. The communication mode reduces the energy consumption level of the dosimeter, so as to prolong the service time of a battery of the electronic dosimeter and reduce the operation cost.
In a specific embodiment, the communication method further includes the following steps:
establishing a data storage area, wherein the data storage area comprises a public data area, a wireless data area and a dosage data area;
storing the current running state information into a public data area;
storing the received command information from the dose reader in the wireless data area; and the number of the first and second groups,
