System 100 may also include a GPS satellite 10 and mounted on the machine 60 the global positioning device (GPS device) 70 (Figure 2 shown), in order to obtain the position information of the machine. The position information of the machine may be forwarded to the control center 30 and/or management center 50. When there is access to the machine when a request for location information, GPS device 70 will begin with the GPS satellite 10 dialogue. Such a request can be in a certain moment planned to send, for example, once per hour. When the time position information is sent to the control center 30, and the information obtained in the other time will be stored in the GPS device 70 until the from the control center 30 of the command.

Figure 2 is shown in the machine according to the present invention is 60 the GPS device 70 illustrative diagram. GPS device 70 can be composed of a battery power supply, usually in the battery when the machine is working the power system by the machine (as shown in the Figure) for charging. Once the machine 60 shut-down, if there is no the present invention provides energy-saving strategy, electric quantity of the battery will be sustained exertion, or even final position information acquisition of the machine will not be given access to. Therefore, in order to avoid stored in the GPS device 70 the data loss in, when the machine is shut down, GPS device 70 must be converted to a sleep mode or standby mode.

GPS device 70, including through the GPS satellite 10 communication to obtain the position information of the position information of the machine module 204. GPS device 70 also comprises the machine 60 and the control center 30 needs to be transmitted between the machine information and/or instruction communication module 202. As shown in Figure 2, GPS device 70 further comprises a CPU210, memory 206 and is used for the machine 60 such as the other components of the sensor by the engine 80 of the engine communication input/output bus 212.

CPU210 as a part of executing a function, can make a request for location information of the machine, and from a position information module 204 information and, through input/output bus 212 from an engine sensor 80 of the machine work information. CPU210 can also be received from the communication module 202 instruction, based on machine position information and/or engine sensor information generating instruction. CPU210 can also manage machine information and instruction in the storage device such as memory 206 in the memory. Furthermore, CPU210 can be detected from the signal of the machine part, such as engine sensor 80, and turns off the GPS device 70 of one or a plurality of functions to power-saving and the more effective with the remote entity communication. For example, when the machine 60 shut down, CPU210 can be only closed position information module 204, hold the control center 30 and machine 60 communication between the.

In one embodiment, GPS device 70 can also include a sent to the CPU210 for generating the signal device, such as a timer 208, the purpose of this signal is the GPS device 70 to return to the working mode. Furthermore, GPS device 70 may also include a sensor for monitoring whether the mobile machine, such as a mobile sensor 214. Mobile sensor 214 can be through the input/output bus 212 with the CPU210 communication. From the mobile sensor 214 can be the signal of the CPU210 detection, and used for activating the GPS device 70 re-start data collection.

Now to Figure 3 the GPS device 70 the sleep mode is determined by the illustrative method. When the machine 60 runtime, GPS device 70 is in a working mode, the sleep mode is not activated. For example, in the working mode, position information module 204 to obtain the position information of the machine, and according to the CPU210 order of, these information is stored in the memory 206 in, so that the communication module 202 after information to the control center of the machine 30. Through the inspection engine sensor 80 signals sent, CPU210 can confirm the machine 60 is closed. If there is no engine signal, such as steps 306 GPS device shown in 70 will enter the sleep mode. Otherwise, GPS device 70 will continue to in working mode.

When the machine 60 is not in operation, GPS device 70 is to enter the sleep mode and one or more of its parts will be closed in order to save energy. Usually the communication module 202 and position information module 204 requires relatively more power, so that when the design needs to be power-saving the CPU210 closing the two element. Clearly, for this field in terms of technical personnel, other components can also be closed in order to minimize power consumption, such as memory 206 also may be closed. However, if the control center 30 requests to the machine 60 uninterrupted communication, the communication module 202 can not be closed. Because the control center 30 through the communication module 202 communicates with the machine, for example, transmit activation GPS device 70 of the instruction, the communication module 202 using more of short cycle timer in order to save the electric quantity.

According to fig. 3 in the step 308, CPU210 determines whether received signal, the signal can be from the timer 208 signal, engine sensor 80 signal, or a mobile sensor 214 of the signal. In the absence of any signal, GPS device 70 will continue to is in a sleep mode. Step 310, if there is a signal, GPS device 70 will be activated. The element is off will be re-power supply. In the power, position information module 204 by the GPS satellite 10 receives real-time position information of the machine, in order to ensure that the machine is not ultra-range mobile. Furthermore, preferably, the communication module 204 will be stored in the memory 206 in which all the machine information is sent to the control center 30.

In steps 312 illustrated, will confirm whether there is a predetermined event. A predetermined event in the more specific explanation will be made, can be, for example, in mobile machine to operate, however, the situation is not detected, mean that the machine may be stolen. If a predetermined event occurs, it is necessary to the control center 30 communication. Otherwise, CPU210 will go back and executing step 304, that is, : can be from the engine by detecting whether the sensor 80 to detect whether the signal of the work machine.

At step 312 the more specific of the combined Figure 4 carry out. Such a predetermined event may be the possible theft 401. If CPU210 detects from the mobile sensor 214 of the signal, but not with a view to the engine sensor 80 signal, can be considered in the transport of the machine, may indicate a possible occurrence of theft. GPS device 70 to the control center 30 report machine 60 and the location information of the wait for further instructions.

Furthermore, a predetermined event may be, if CPU210 detects that the GPS device 70 to the capacity of the battery is extremely low level or "a preset percentage" 402, such as to reduce to the maximum amount of 10%. In this circumstances, CPU210 will require communication module 202 immediately to the control center 30 of the report all updated information of the machine, in the GPS device 70 and stored machine power-off is not possible before the data of the data record. Furthermore, the control center 30 to the machine 60 the operating staff send information replacing or charging the battery.

Furthermore, a predetermined event can also is that the control center 30 requests communication 403. For example, the control center 30 can be preprogrammed in a preset time point, such as one time every two hours, automatically collect data of the machine continuously and not collect, in order to save power consumption and mobile communication system 20 of a plurality of communication resources. If the GPS device 70 in the pre-set of the machine information report time point is activated, communication module 202 the machine all the information will be sent to the control center 30.

Although the above description of the disclosed embodiment of machine and system, but this invention can be suitable for any of the GPS system to use the local wireless communication system from the environment or circumstances, the GPS of the machine through the installation apparatus and processing data communication with control center. The below described industrial practicability of the present invention.

In the application, comprises communication module 202 and position information module 204 of the GPS device 70 may be mounted on machine 60 in, used for machine 60 and a control center 30 communication between the. The machine 60 operates, GPS device 70 is in a working mode, that is, : position information module 204 periodically receiving location information of the machine, these information can be via the communication module 202 are transmitted to the control center 30. In this way, the hope that GPS device 70 by the full battery power supply, because the alternating current generator or a generator of an intermittent charging the battery. When the machine 60 or is turned off is power-off, GPS device 70 can only by the battery power supply, and if the GPS device 70 does not stop during the collection of data, there will be fear that the battery of the invention.

According to fig. 3, when detecting the machine 60 when the stop operation, GPS device 70 will enter to a sleep mode in order to save battery power. In the sleep mode, one or more elements will be shut off, for example, position information module 204 and communication module 202. Only when the signal is received the, GPS device 70 will be activated. Such signal can be from a mobile sensor 214 signal, engine sensor 80 signal, or a timer 208 signal. When the GPS device 70 is activated, will judge whether a predetermined event occurrence. If there is a predetermined event, GPS device 70 with the control center 30 communication and wait for the arrival of the instruction.

As shown in Figure 4, a predetermined event may be referred to possible theft 401, power level 402, the communication or request 403. For example, engine sensor 80 no signal but the mobile sensor 214 with a signal, stealing will be taken into account. GPS device 70 to the control center 30 report, in order to protect the property, the control center 30 may send a command to lock the machine or so that the machine is not able to work, or tracking movement of the machine, or transmitting the warning message to the local police authorities, so as to protect the machine.

The invention provides a system and a method can be passed, in the sleep mode and a work mode switch mechanism between the modes, the electricity consumption of the battery of GPS device. And this invention the provision of the predetermined event can prevent the machine from being stolen, this is the risk of the emerging market there is a huge problem, remote control center monitoring the capacity of the machine. Furthermore, as can be seen, the technical scheme of the invention can in the local cellular communication system, communication cost is low.
