However, if the GSM / GPRS signal is unstable or there is no signal, it may be the reason for insufficient GSM / GPRS signal coverage, or it may be the reason for man-made malicious shielding of the GSM / GPRS signal, or even the removal of the GPS device. Out of the monitoring center's "field of view", in some cases, it will cause property damage. For example, due to the arrears of the vehicle's balance payment and cannot be repaid, the method of interfering with the normal operation of the GPS terminal is used to maliciously block the GSM / GPRS signal, so that the monitoring center cannot Determining the location of construction machinery vehicles

Embodiment 1
[0023] Such as figure 2 Shown, embodiment one of the self-locking method of engineering machinery vehicle described in the present invention, this real embodiment adopts such as figure 1 The shown self-locking system realizes, and it comprises the following steps:
[0024] Step 10, the GPS terminal 22 installed on the engineering vehicle 20 attempts to communicate with the remote monitoring center 10 through the GPRS network within each predetermined time interval T1.
[0025]In order to send the current state of the engineering vehicle 20 and relevant engineering data to the monitoring center 10 in time, the GPS terminal 22 attempts to communicate with the monitoring center 10 through the GPRS network. The time length of the time interval T1 can be set by the monitoring center 10, for example, T1 is a time interval of 1 minute or 5 minutes.
[0026] Step 20, if the GPS terminal 22 is successfully connected to the monitoring center 10 through the GPRS network, then go to st...
Embodiment 2
[0044] Such as image 3 As shown, the present invention provides another embodiment of the self-locking method for construction machinery vehicles. The difference between this embodiment and the first embodiment lies in: between step 20 and step 30 .
[0045] In this example,
[0046] Step 20, the monitoring center 10 and the GPS terminal 22 are successfully connected through the GPRS network.
[0047] Step 25, if there is a record of the connection between the GPS terminal 22 and the monitoring center 10 through the GSM network within the predetermined time interval T5, then go to step 50, otherwise go to step 30.
[0048] Step 30 , the monitoring center 10 and the GPS terminal 22 of the engineering vehicle 20 perform data interaction through the GPRS network, and go to step 10 after the communication is completed.
[0049] And step 10, step 40 to step 90 are consistent with the first embodiment. Therefore, by adopting the judging method in step 25, it is possible to avoi...

Abstract
The invention discloses a self-locking method and system for engineering mechanism vehicles. The system includes a remote monitoring center, a GPS terminal installed on the engineering vehicle and electrically connected to each other, a wireless communication module, and a vehicle-mounted controller; the monitoring center passes through the wireless communication module. Communicate with the GPS terminal to obtain the current status information of the engineering vehicle; the wireless communication module includes a GPRS communication module working in the GPRS working mode and a GSM communication module working in the GSM working mode; the wireless communication module determines its own status according to the stable state of the wireless network. working mode, and notify the on-board controller to control the self-locking / unlocking state of the engineering vehicle. Using the above scheme, when the GPRS / GSM network signal is continuously low, the GPS terminal will self-lock the engineering vehicle through the on-board controller to prevent the engineering vehicle from leaving the monitoring center's "vision" and causing property damage.
Description
technical field [0001] The invention relates to a self-locking method and system for engineering mechanism vehicles. Background technique [0002] With the continuous development of GPS vehicle terminal technology, it has been widely used in the construction machinery industry. Construction machinery vehicles are generally complex in structure and expensive, so they are often sold on the basis of mortgage and installment payment. The manufacturer or seller of engineering vehicles will install the GPS terminal on the engineering vehicle as a means of remote monitoring of the vehicle, and upload the location information and engineering data of the vehicle to the monitoring center in real time, and remotely control the operation of the vehicle according to the instructions of the monitoring center if necessary. For example, the GPS terminal performs the operation of locking the car according to the instructions of the monitoring center. In this way, it can ensure that the dri...
