摘要： PURPOSE:To improve monitoring accuracy, in a monitoring device of frame stress in a truck or the like, by constituting the device in such a manner that frame stress is arithmetically obtained from pressure applied to a suspension and a pulse signal is output for within a range of prescribed stress to generate a display and alarm. CONSTITUTION:Pressure applied to each suspension is detected by sensors 11-14 and input to an adder 23 through amplifier circuits 15-18, respectively having a prescribed amplification factor, and high frequency component removing filters 19-22. The adder 23 inputs a stress detection signal Ssigma to a sample holding circuit 25 through an absolute value forming circuit 24. Output of the circuit 25 is compared with limit value of level setters 30-32 in comparators 27-29. In accordance with this condition, a pulse signal PO of an oscillator circuit 39 is applied to multivibrator circuits 40-42 to drive counters 43-45 and turn on a lamp 52 through a driver circuit 51 and relay 50. In this constitution, a display is performed simultaneously monitoring accuracy can be improved.

摘要： PURPOSE:To set the transfer rate of transmission unit in optimum state, by including the transfer rate in the transmission information so that the transfer rate can arbitrarily be changed. CONSTITUTION:When the system power supply is turned on, transfer is started with the reference transfer rate To together with the master station 1 and slave stations 2, 3. The information A from the master station includes the control information to the slave station and the transfer rate information. The transfer information is similarly included in the information fed from the master to slave station and this is the confirmation response signal to the master station. When the master station receives information from the slave station, the confirmation response signal is delivered to the slave station, and the transfer rate is selected to Ta after a given time. When the slave station receives the confirmation response signal from the master station, the transfer rate is immediately selected to Ta. Thus, the master and slave station forms the transmission system of the transfer rate Ta and it is kept if the transfer rate alteration instruction is not delivered from the master station. As to other slave stations, this can be applied similarly.

摘要： PURPOSE:To enable continuous and dynamic monitoring and facilitate the diagnosis of abnormalities, by sampling the wave form of feeding of a sheet at a prescribed rate to determine the difference between the wave form and a reference wave form to identify the excess of the difference over an allowable limit with an abnormality. CONSTITUTION:When a training button 8 is pressed after the starting of the feeding of a sheet in a set mode, the wave form of the feeding of the sheet is sampled at a rate set by a timer circuit 7 and the sampled wave form is stored in a random access memory 4. The stored wave form is set as a reference pattern for the following wave form of the feeding. The stored and the following wave forms are compared with each other. When the difference in command speed between the time series of both the wave forms has exceeded an allowable value, it is diagnosed as an abnormality and warning is given. The feeding of the sheet is thus continuously and dynamically monitored to facilitate the diagnosis of the abnormality.

摘要： PURPOSE:To simplify the adjustment of velocity pattern, and to facilitate the alteration of the velocity pattern, by carrying out the setting process for the velocity pattern of the feed roll and the velocity change pattern with the aid of microcomputer. CONSTITUTION:The difference between the feedback pulse train PL2 and the velocity command pulse train PL1 is counted by the deviation counter 12 through the synchronous circuit 11, and is converted to the analog value by D/A 13; this analog value is inputted to the servo-amplifier 15 through the nonlinear amplifier 14. The velocity command pulse train PL1 is generated by the pulse distributer 16 which receives the clock pulse CL2. The pulse distributer 16 changes the distribution rate of the clock pulse CL2 according to the velocity control pattern signal inputted through the input and output port 17. The CPU20 stores position command information in the RAM19 through the input and output port 17 and the internal bus 21, and reads information of ROM18 and RAM19, and produces it as the velocity control pattern signal BP which is thereupon inputted to the pulse distributer 16 through the internal bus 21 and the input and output port 17.

摘要： PURPOSE:To prevent a reckless run by automatically a process by inserting a specific instruction for a reckless-run check into a processing program and then by executing this routine once in a certain time without fail. CONSTITUTION:In processing program PGM, a specific reckless-run check instruction RCD is written at a fixed address. In a certain processing time, this routine containing this reckless-run check instruction is executed once without fail. Then, actuating a computer clears counters CUT1 and CUT2 by power-feeding signal PO and CUT1 starts counting clock pulses Pc. The computer, on the other hand, executes instructions according to processing program PGM. Through the execution of instruction RCD in PGM, counters CUT1 and CUT2 are cleared by a signal from decoder DEC and carry signal CA2 is not outputted. Once a reckless run occurs, instruction RCD is not executed, and consequently counter CUT2 overflows to output signal CA2, causing an actuation stop.

摘要： PURPOSE:To surely perform detection of stress which is applied on a frame of a dump truck or so by detecting each of pressure respectively applied on four suspension devices which support the frame and computing the stress applied thereon on the basis of the detected values. CONSTITUTION:A pressure susceptive member is disposed at each of air extraction valves of four suspensions filled with a gas not illustrated, and pressure sensors 6-9 are arranged. The pressure sensors 6-9 detect pressures P1-P4 which are applied on the suspensions, respectively and input into an adder 18 via amplification circuits 10-13 of which each has an amplification ratio determined by a construction of a car body and characteristics of the suspensions and via filters 14-17 which remove signals produced by vibration of the car body or other reasons. The adder 18 adds up those four inputs and generates a stress detective signals Ssigma to actuate a needed device such as a display or so. Hence, the fitting is easy and the stress applied on the frame may be surely detected.
