Problems solved by technology

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 As shown, the first embodiment of the self-locking method for construction machinery and vehicles according to the present invention, this embodiment adopts figure 1 The implementation of the self-locking system shown includes 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 via the GPRS network within each predetermined time interval T1.

[0025] In order to be able to send the current status of the engineering vehicle 20 and related engineering data to the monitoring center 10 in time, the GPS terminal 22 attempts to communicate with the monitoring center 10 through a 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] In step 20, if the GPS terminal 22 and the monitoring center 10 are successfully connected through the GPRS network, then...

Embodiment 2

[0044] Such as image 3 As shown, the present invention provides another embodiment of a 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 embodiment,

[0046] Step 20: The monitoring center 10 and the GPS terminal 22 are successfully connected through the GPRS network.

[0047] Step 25: There is a record of the connection between the GPS terminal 22 and the monitoring center 10 via the GSM network in the predetermined time interval T5, then go to step 50, otherwise go to step 30.

[0048] In step 30, the monitoring center 10 and the GPS terminal 22 of the engineering vehicle 20 exchange data through the GPRS network, and go to step 10 after the communication ends.

[0049] Step 10, step 40 to step 90 are consistent with the first embodiment. Therefore, the judgment method in step 25 can be used to prevent the GPRS network from temporarily recovering and enter...

Abstract

The invention discloses a self-locking method and a self-locking system of an engineering machinery vehicle. The system comprises a monitoring center located remotely, a GPS (global positioning system) terminal, a wireless communication module and a vehicle-mounted controller, the GPS terminal, and the wireless communication module and the vehicle-mounted controller are mounted on the engineering vehicle and electrically connected with one another. The monitoring center communicates with the GPS terminal through the wireless communication module so as to acquire current state information of the engineering vehicle. The wireless communication module comprises a GPS communication module working in a GPS working mode and a GSM (global system for mobile communications) communication module working in a GSM working mode, determines a self working mode according to a stable state of a wireless network, and informs the vehicle-mounted controller of controlling self-locking / unlocking states of the engineering vehicle. By the scheme, when GPRS (general packet radio service) / GSM network signals are detected to be weak continuously, the GPS terminal performs self-locking control on the engineering vehicle through the vehicle-mounted controller, and accordingly the engineering vehicle is prevented from being out of a 'vision field' of the monitoring center to cause property loss.

Description

Technical field [0001] The invention relates to a self-locking method and system for vehicles of engineering institutions. 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 by mortgage and installment payments. The manufacturer or seller of construction vehicles will install GPS terminals on construction vehicles as a means of remotely monitoring vehicles, and upload the vehicle's positioning information and engineering data to the monitoring center in real time, and remotely control the operation of the vehicles according to the instructions of the monitoring center when 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 driver can keep in to...
