Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-5, the present invention provides a technical solution: a signal simulation box for testing a gas cylinder cabinet controller comprises a signal simulation box 11, a gas cylinder cabinet controller 21 and a gas cylinder cabinet 22, wherein the signal simulation box 11 is connected with the gas cylinder cabinet controller 21 through a lead, and the gas cylinder cabinet controller 21 is detachably connected with the gas cylinder cabinet 22;
the signal simulation box 11 is used for simulating and outputting a controller signal according to the gas cylinder cabinet controller 21;
the controller signal includes a digital signal and an analog signal;
the signal simulation box 11 includes a digital signal toggle switch 31, an analog signal knob 32, a fixed resistor 52 and a variable resistor 53; the gas cylinder cabinet controller 21 comprises a programmable logic controller 51;
the digital signal toggle switch 31 and the analog signal knob 32 are connected to the programmable logic controller 51 respectively;
the programmable logic controller 51 comprises a circuit interface, and the fixed resistor 52 and the variable resistor 53 are respectively connected in series with the circuit interface;
the fixed resistor 52 and the variable resistor 53 are used for providing analog output voltage, and the output voltage range is 0-10V.
In a further embodiment, the digital signal toggle switch 31 comprises an ON key and an OFF key;
the ON key is used for controlling the passage of the circuit;
and the OFF key is used for controlling the disconnection of the circuit.
In a further embodiment, the resistance of the fixed resistor 52 is a fixed value of 10 Kohm; the resistance condition of the variable resistor 53 ranges from 0Kohm to 10 Kohm.
In a further embodiment, the fixed resistor 52 and the variable resistor 53 are provided in pairs, and the number of loops formed by the fixed resistor 52 and the variable resistor 53 is at least one.
It should be noted that the signal simulation box 11 provides a simulation output for the signal required by the gas cylinder cabinet controller test. The controller signals have 2 types, one is a digital signal and the other is an analog signal. As shown in FIG. 3, the upper row of toggle switches 31 can provide digital signals; the lower knob 32 can provide analog signal;
referring to FIG. 4, for digital signals, the sources of such signals are: remote Shutdown (RSD), toxic gas leak alarm, earthquake alarm, flame detection alarm, of the on/off nature, simulated 31 with a toggle switch on the simulation box. When the shifting lever is shifted upwards to On, a passage is formed, and when the shifting lever is shifted to Off, the circuit is broken. The whole control circuit thereof;
for analog signals, the external sources of such signals are gas pressure readings and gas cylinder weight readings. Most of the present gas cylinder cabinet controllers adopt Programmable Logic Controllers (PLC) (51) as core operations, so the simulator performs simulation with 0-10V Analog Input (AI) in cooperation with PLC. The simulation box simulates the voltage variable by a variable resistor to achieve the analog value required by the controller. The control circuit is shown in fig. 5. In order to generate a voltage output of 0-10V, a loop is designed, 1 fixed resistor 52 of 10Kohm is connected in series with a 24V circuit, then 1 variable resistor 53 of 0-10Kohm is connected in series, and then the voltage before and after the variable resistor is accessed, so that a voltage output value of 0-12V can be obtained, which just meets the voltage input value of 0-10V interval accepted by a PLC. In fig. 5, one of the loops is made, the other loops are all the same, and the number of the loops is adjusted according to the actual requirement of the controller;
in addition, as shown in fig. 1, after the signal of the gas cylinder cabinet controller simulation box 11 is connected to the controller, various analog and digital signals required in the gas cylinder cabinet control program test can be simulated, so that the gas cylinder cabinet controller does not need to be installed on the gas cylinder cabinet, and the software program can be tested.
