Abstract
The utility model discloses a remote fault diagnosis device for a hydraulic system of a forklift. The remote fault diagnosis device comprises a PLC. The PLC is connected with an extension module, a displayer, a buzzer and a GPRS wireless data communication module. The other end of the extension module is connected with an oil temperature sensor, an oil pressure sensor and a displacement sensor. The GPRS wireless data communication module is connected with a remote computer through a GPRS network, an ADSL modulator-demodulator and a firewall. The remote fault diagnosis device is high in communication speed, good in real-time performance and high in reliability, and can learn the operating state of the hydraulic system of the forklift in time, determine the fault point of the forklift in time through remote analysis of operating parameters, provide the information such as related fault reasons and fault occurrence portions for maintainers, provide technical support for early discovery of the faults, maintenance and repair for the forklift, improve the work efficiency of service staff, reduce the loss of users and avoid the faults.
Description
Technical field
The utility model belongs to fork truck manufacturing technology field, relates to a kind of forklift hydraulic system remote fault diagnosis device.
Background technique
Fork truck is industrial transportation vehicle, refer to member pallet cargo load and unload, the various wheeled carrying vehicle of stacking and short distance hauling operation.Forklift hydraulic system is the important component part of fork truck.But the pipeline circulatory system of hydraulic pressure system subordination sealing, hydraulic system fault is stealthy, failure reason analysis difficulty is large, be difficult to diagnosis.And common way has two kinds: the one, applying unit is equipped with a professional equipment and safeguards troop, but due to the restriction of personnel and fund, there is blind spot in a lot of applying units in this regard; The 2nd, manufacturer selects and appoints attendant to go on site fault clearing, but due to ageing and restriction Economy, is also difficult to meet the needs of applying unit, has also increased manufacturer's maintenance cost simultaneously.
Model utility content
The purpose of this utility model is to provide a kind of forklift hydraulic system remote fault diagnosis device, the technical problem that maintenance difficult, maintenance efficiency are low, maintenance cost is high existing to overcome prior art.
The technological scheme that the utility model adopts is, a kind of forklift hydraulic system remote fault diagnosis device, its feature is: comprise PLC controller, PLC controller is connected with expansion module, remote control respectively, and the other end of expansion module is connected with oil temperature sensor, displacement transducer and some oil pressure sensors.
The utility model compared with prior art tool has the following advantages: the utility model is by the Real-Time Monitoring to each operation parameters state of forklift hydraulic system, analyze, can understand in time the running state of fork truck, and can pass through the remote analysis to Operational Limits, determine in time the fault point of fork truck, for maintainer provides relevant failure cause, the information such as fault happening part, early detection to fork truck fault, maintenance, safeguard with reparation technical support is provided, can not only improve attendant's working efficiency, reduce user's loss, after can also avoiding fault to occur, work on, cause larger fault, extension device working life, in addition, GPRS network has that transfer rate is fast, turn-on time is short, networking is simply changeable, charging policy is flexible, anti-lightning strike and without advantages such as link maintenance work, so native system communication speed is high, real-time good, reliability is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
