Embodiment
It is below in conjunction with the accompanying drawings and specific real to make those skilled in the art be better understood from the technical solution of the utility model
Example is applied to elaborate to the utility model.
Embodiment of the present utility model discloses a kind of accuracy monitoring applied to aerial work platform weighing sensor and filled
Put, as illustrated, it include controller 1, control unit interface module 2, pressure sensor 1, pressure sensor 24, circuit 5,
Fix bar 6, force rod 7, vehicle frame 8, undercarriage 9 and job platform 10,
The top outer surface of vehicle frame 8 is fixed with undercarriage 9, and the top of undercarriage 9 is fixed with job platform 10；Rise and fall
The middle part of frame 9 is fixed with force rod 7, and one end of force rod 7 is fixedly connected with undercarriage 9, and the other end bottom of force rod 7 is with consolidating
One end of fixed pole 6 is fixedly connected；The other end of fix bar 6 is fixedly mounted on the top outer surface of vehicle frame 8；Force rod 7 is close to solid
One end of fixed pole 6 is fixed with pressure sensor 1 and pressure sensor 24；The inside of vehicle frame 8 is provided with controller 1 and controller
Interface module 2.
In the present embodiment, pressure sensor 1 and pressure sensor 24 pass through the access controller interface module of circuit 5
2；The access controller 1 of control unit interface module 2.
In the present embodiment, pressure sensor 1 and pressure sensor 24 are electrically connected with controller 1.
In the present embodiment, the weighing system on aerial work platform is that the pressure sensor being equipped with by measuring on oil cylinder is surveyed
In-oil cylinder pressure value, the pressure value of collection is converted into sensor into voltage signal that system can identify or electric current is believed
Number.This collection voltages signal or current signal pass to control unit interface module input controller simultaneously, and controller is to two-way
Collection signal is compared contrast, and two sensor signals mutually verify detection, if voltage or electricity between two sensors
Flow difference within a certain fixed value either the voltage of two paths of signals or current value and in a certain defined scope, system
Normally, without any alarm signal, if readings exceedes defined intrinsic scope, system thinks to have all the way that sensor accuracy is not
Standard, system have error signal；Now user needs to check installation and its precision of weighing sensor in time；There is this mutually school
Function is tested, reduces measured deviation and false alarm that single sensor is brought.
The utility model is described in detail above by embodiment, but the content is only of the present utility model shows
