Abstract

The utility model relates to the field of fork-lift truck remote control and discloses a remote monitoring system of an electric fork-lift truck. The remote monitoring system of the electric fork-lift truck comprises a control unit, a master controller, a communication module and a positioning module, wherein the control unit controls a fork-lift truck controller of the electric fork-lift truck, the positioning module acquires position information, the communication module transmits and receives information, and the master controller reads the information and an instruction received by the communication module to perform distinguishing and judgment and execute corresponding operation. The master controller controls the control unit which is a metal-oxide-semiconductor field effect transistor (MOSFET), and the MOSFET controls connection and disconnection of a signal line of the fork-lift truck controller. The remote monitoring system can perform remote control to stop the electric fork-lift truck timely by means of the MOSFET and a global system for mobile communication (GSM) network. Besides, the position and track records of the fork-lift truck can be seen through the GSM network, so that real-time monitoring on the fork-lift truck can be performed.

Description

The electri forklift long distance control system

Technical field

The utility model relates to the fork truck remote control field, particularly a kind of electri forklift long distance control system.

Background technology

In the process of the lease of fork truck or hire-purchase fork truck, fork truck travels outside, controls at any time vehicle in order to ensure its security needs; And often need to grasp in real time to look into fork truck present position and vehicle operating track, in order to understand fork truck trend and use state etc.If the abnormal situation needs in time to control the operation of fork truck or stop.

Summary of the invention

The utility model is for the deficiencies in the prior art, provide a kind of can Real Time Monitoring fork truck present position and the electri forklift long distance control system that stops of vehicle operating track and the operation of control fork truck.

The electri forklift long distance control system, comprise control module, the fork truck controller of control module control electri forklift, also comprise master controller, communication module, locating module, locating module obtains positional information, and communication module sends and receives information, and master controller reads information and the instruction that communication module receives, identify judgement, carry out accordingly operation; Main controller controls control module, control module are MOSFET, the break-make of the signal wire of MOSFET control fork truck controller.MOSFET(is metal-oxide half field effect transistor, and Metal-Oxide-Semiconductor Field-Effect Transistor is a kind of field-effect transistor that can be widely used in mimic channel and digital circuit).

As preferably, communication module is sent to client mobile phone with short message mode with positional information by the GSM network.

As preferably, then the master controller process information is sent to server end by GPRS network.

The utility model is shut down by MOSFET and the at any time remote control of GSM network, can see by GPRS network position and the track record of fork truck simultaneously, and fork truck is carried out Real Time Monitoring.

Description of drawings

Fig. 1 is schematic flow sheet of the present utility model.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing, but be not limited to this.

Electri forklift is provided with fork truck controller, and fork truck controller has a signal wire, and this signal wire is exported from fork truck controller, gets back at last fork truck controller; The closed and disconnected of the control module control signal wire of electri forklift long distance control system, thus control fork truck operation and stop.

As shown in Figure 1, the electri forklift long distance control system comprises master controller, communication module, locating module and control module.

Locating module obtains positional information, and locating module is realized obtaining of positional information by the GPS positioning system.

Communication module mainly is responsible for sending and receiving information.Positional information after communication module is processed master controller is sent to server end by GPRS network, and the client is by using the client software access server to obtain positional information; Communication module also can be sent to client mobile phone with short message mode with positional information by the GSM network.Communication module can receive the instruction to the client, and master controller can be carried out corresponding operation.

Master controller is core, and it reads information and the instruction that communication module receives, and identifies judgement, carries out accordingly operation.Simultaneously master controller is crossed communication module with some information exchanges and is sent, and reads the positional information of locating module such as master controller, sending by communication module after processing.

The main controller controls control module, the break-make of control module control electric forklift controller signal wire.The control function of control module is realized by MOSFET, the break-make of MOSFET control signal.MOSFET is the switch of a power consumption control, and is little than the relay volume, and switch motion can not sound, and when a small size voltage is applied on the MOSFET, MOSFET is closed conducting, otherwise then disconnects.The small size voltage of main controller controls, slightly voltage is 48V.

Master controller receives cut-offing instruction, and the main controller controls control module disconnects MOSFET, thereby signal wire is disconnected, and fork truck controller is not worked, and fork truck quits work; Master controller receives operating instruction, and the MOSFET of main controller controls control module is closed, and the signal wire input end is small size voltage, and controller can be carried out operation.

In sum, the break-make of this long distance control system by this signal wire of control realize the Long-distance Control fork truck work whether.
