For small portable equipment such as a mobile hard disk, a special battery needs to be designed for the small portable equipment to complete basic functions such as message response, a destruction position and the like, and if the residual electric quantity cannot ensure that data is completely destroyed, the equipment can judge the destruction identification position after being powered on and continue to complete the rest operation. If the portable equipment cannot complete the response of the destruction instruction due to the exhaustion of the electric quantity, the portable equipment is intentionally or unintentionally powered on at the later stage and then is firstly reported to the server, and the server continues to issue the destruction instruction after receiving the power-on information of the portable equipment. In terms of software functions, the destroying operation is mainly divided into two modes: (1) actively destroying remote data, wherein a server administrator inquires the real-time position of the portable equipment and issues a destroying instruction when the equipment is out of control; (2) according to the safe distance judgment threshold value, automatic destruction is carried out, the distance threshold value is set when the portable equipment is registered through the server management computer, the threshold value is stored in the management computer and the portable equipment for redundancy judgment, when the portable equipment is in work, the two parties share position information through respective Beidou communication units, and when any party finds that the actual distance exceeds the threshold value, information destruction is carried out on the portable equipment. The method comprises the steps that the portable equipment sends a file identification code in a storage area to a server before destruction operation is completed, a result is fed back to a management system server after destruction is completed, and an administrator can check the identification code, registration information, the file identification code before destruction, a destruction state and position information of the portable equipment through list information of the server;
the destroying module comprises a control chip, a destroying device and a storage area.
The control chip is used for analyzing message commands of the server and issuing commands, and meanwhile, monitoring the destruction condition of the storage area and reporting results to the server;
the destroying device is used for erasing the storage area by software, and can be converted into a physical destroying device if the energy of the portable equipment is sufficient.
In the embodiment of the invention, before using the management system, an administrator needs to register the portable equipment, the portable equipment is connected to the management computer through the USB interface, the computer reads the unique identification code and the equipment information in the control chip of the portable equipment and completes the registration, the service end issues an instruction to activate the Beidou communication unit of the client, the service end and the client start to share the position information, and the administrator sets the safety distance judgment threshold according to the management requirement.
After the registration is completed, the equipment is used in a safe distance threshold range, Beidou positioning is performed by adopting an RNSS + RDSS combined working mode, the mode enables a ground operation control system to have information processing and operation control capabilities at the same time, has user signal random access capability, can process short burst information, completes information exchange from a user to a central control system, signals of the two can be used for navigation and communication information at the same time, a terminal user has RNSS and RDSS functions at the same time, and continuous positioning, speed measurement, communication and position reporting are realized at the same user terminal.
And the RNSS is used for system positioning, the hot start time of the first positioning is not more than 15s, the warm start is not more than 120s, and the refresh period is 1 s. The RDSS is used for communication and positioning, the first capture time is not more than 2s, and the lock losing recapture time is not more than 1 s. Taking client positioning as an example, after the Beidou system is started, the RNSS is started immediately to capture a satellite, position information is calculated through the acquired satellite signal and then sent to the RDSS, and a short message is sent in the RDSS to inform a server system. If the RNSS does not receive the location information within a specified time, that is, within one minute of starting to acquire the satellite, the RNSS switches to the active location method adopted by the RDSS to acquire the satellite again, sends a signal, receives the satellite location information, calculates the location information, and then sends the information, wherein the RNSS work flow is as shown in fig. 3, and the RDSS work flow is as shown in fig. 4.
After the position sharing and the short message communication establishment are successful, the system enters a destruction waiting state, the process is as shown in fig. 5, when the calculated distance between the server and the client exceeds the threshold, the destruction operation is started, and the server records the event. If the distance between the two parties is within the threshold range, the administrator starts a remote active destruction function according to the out-of-control state of the portable equipment, the server side records the event, and the client side starts destruction operation. Before destruction, the client reports the electronic file information to the server, after destruction is completed, the client reports the server destruction result through the Beidou communication unit, and if destruction is not completed all the time and exceeds a time threshold, the client reports an overtime judgment result and a destruction progress to the server.
